Old boy network

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Old_boy_network

An old boy network (also known as old boys' network, old boys' club) is an informal system in which wealthy men with similar social or educational background help each other in business or personal matters. The term originally referred to social and business connections among former pupils of male-only elite schools, though the term is now also used to refer to any closed system of relationships that restrict opportunities to within the group. The term originated from much of the British upper-class having attended certain fee-charging public schools as boys, thus former pupils are "old boys".

This can apply to the network between the graduates of a single school regardless of their gender. It is also known as an old boys' society and is similar to an alumni association. It can also mean a network of social and business connections among the alumni of various prestigious schools. In popular language, old boy network or old boys' society has come to be used in reference to the preservation of social elites in general; such connections within the British Civil Service formed a primary theme in the BBC's satirical comedy series Yes Minister. The phrase "It's not what you know, it's who you know" is associated with this tradition.

Australia

In Australia, the term "Old Boy" is used to describe a male alumnus of some prestigious state and private schools. The term "Old Girl" is similarly used for a female alumna of such schools. Both "Old Girl" and "Old Boy" are sometimes used as a reference to someone's parents.

Canada

The term is also used in Canada, where the alumni of such schools as St. Andrew's College, Trinity College School, Crescent School, St George's School, Vancouver College, Stratford Hall, Bishop's College School, Hillfield Strathallan College, Collège Jean-de-Brébeuf, Lower Canada College, and Upper Canada College are known as Old Boys. Other influential private schools with powerful alumni networks may have become co-ed, such as Appleby College or University of Toronto Schools, but operate similarly in which large numbers of alumni all work for the same organization.

Finland

In Finland, the Finnish term hyvä veli -verkosto (literally dear brother network) is used to refer to the alleged informal network of men in high places whose members use their influence to pervert or circumvent official decision-making processes to the members' mutual benefit. As such, the term is pejorative.

The term derives from the salutation "Hyvä veli!", or "Dear brother!", traditionally used to open a letter to a not quite intimate friend. The implication is that since the elites of all fields are drawn from a fairly small pool of people who are mostly more or less acquainted with each other, they can and often do manage public and private affairs amongst themselves, off the record, and outside public scrutiny as they like. As the word "brother" implies, the network is usually presumed to be consisting of males, and thus the term is also sometimes used to refer to the marginalization of women and their exclusion from high positions in both the public and private spheres. There is an equivalent term, hyvä sisko ("dear sister"), used in reference to informal networks of women in high positions.

President Urho Kekkonen was notable for directly communicating with senior officials (past his cabinets) by means of letters, which famously began with the salutation "Hyvä veli". These have been published in three volumes.

Hong Kong

The term can also refer to the networks that are set up in the more elite secondary schools, such as Diocesan Boys' School, Queen's College, Ying Wa College, La Salle College and Saint Joseph's College.

India

The Doon School maintains its own old boys' society (The Doon School Old Boys' Society) for social connections and fundraising on behalf of the School. Graduates of The Doon School are known as Doscos, or simply, Old Boys.

Former students of the Welham Boys School refer to their society as the Welham Old Boys Society. Though the school was founded in 1937, the society was not founded until 1983. The group is intended to encourage Welham graduates to aid in the school's success through their union; they have established scholarships and bursaries for deserving students. The Welham Old Boys Network has established definite membership criteria, as well as requiring a subscription fee.

Former pupils of Bishop Cotton School are referred to as Old Cottonians. The Old Cottonians Association was started in 1910 when 17 Old Cottonians assembled in the Freemason's Hall in Shimla. The Old Cottonians Association is spread all over the world.

Similarly, the Old Boys of Sainik School Rewa in Madhya Pradesh call their Old Boys Association as "Sainwinians".

Aligarh Muslim University Alumni had established AMU alumni associations all over India and elsewhere.

Some of the other schools to use the term are La Martiniere Calcutta, La Martinière College Lucknow, Mayo College, Mayo College Girls School, St. Paul's School Darjeeling, St. Edward's School Shimla, The Lawrence School Sanawar, Bishop Cotton Boys' School.

New Zealand

In New Zealand, many schools maintain old boys/girls/students associations, but the term "old boy network" is typically used in reference to the elite public and private secondary schools such as Auckland Grammar School, King's College, Sacred Heart College, Christ's College and Scots College.

Switzerland

In Switzerland, the term can be used for the networks set up by the alumni organizations of private boarding schools such as Institut Le Rosey, Aiglon College, College Alpin International Beau Soleil, and College du Leman. These elite Swiss private schools are considered to have among the most prestigious alumni registries, with Switzerland having the highest private school fees in the world; these institutions attract the children of royalty, celebrities, political leaders and business executives. Strong old boys/girls network also exist in private universities, notably École hôtelière de Lausanne and Les Roches International School of Hotel Management.

United Kingdom

In the United Kingdom, the "old boy network" is seen as existing primarily among those educated at the fee-paying independent schools (public schools) of the Eton Group and the Rugby Group including, but not limited to, Charterhouse School, Eton College, Harrow School, Oundle School, Radley College, Rugby School, Sherborne School, Shrewsbury School, Stowe School, Wellington College, Westminster School and Winchester College, as well as at the colleges of Oxford and Cambridge, although to some extent such networks exist for all institutions producing large numbers of "old boys" and girls. The existence of "old boy" networks is often blamed for the high proportion of former pupils of high-status schools and universities in high-status positions in government, business, and other professions. For instance, between them, Harrow and Eton have 26 British prime ministers among their old boys. In practice, attendance at certain educational institutions is typical of the British "ruling class" and upper middle class, and where nepotism exists it may be driven more often by personal relationships than by educational networks.

An organisation called Future First promotes the use of such networks among those educated at state schools.

United States

In the United States, the "Old Boys Network" is a term more focused on the inside track with connections to powerful and ambitious individuals formed through work, professional and community service organizations, and private clubs. However, the original term of being associated with education has sometimes also been used in this context.

Muscle cell

From Wikipedia, the free encyclopedia

Muscle cell
General structure of a skeletal muscle cell and neuromuscular junction:
  1. Axon
  2. Neuromuscular junction
  3. Skeletal muscle fiber
  4. Myofibril A muscle cell, also known as a myocyte, is a mature contractile cell in the muscle of an animal. In humans and other vertebrates there are three types: skeletal, smooth, and cardiac (cardiomyocytes). A skeletal muscle cell is long and threadlike with many nuclei and is called a muscle fiber. Muscle cells develop from embryonic precursor cells called myoblasts.

Skeletal muscle cells form by fusion of myoblasts to produce multinucleated cells (syncytia) in a process known as myogenesis. Skeletal muscle cells and cardiac muscle cells both contain myofibrils and sarcomeres and form a striated muscle tissue.

Cardiac muscle cells form the cardiac muscle in the walls of the heart chambers, and have a single central nucleus. Cardiac muscle cells are joined to neighboring cells by intercalated discs, and when joined in a visible unit they are described as a cardiac muscle fiber.

Smooth muscle cells control involuntary movements such as the peristalsis contractions in the esophagus and stomach. Smooth muscle has no myofibrils or sarcomeres and is therefore non-striated. Smooth muscle cells have a single nucleus.

Structure

The unusual microscopic anatomy of a muscle cell gave rise to its terminology. The cytoplasm in a muscle cell is termed the sarcoplasm; the smooth endoplasmic reticulum of a muscle cell is termed the sarcoplasmic reticulum; and the cell membrane in a muscle cell is termed the sarcolemma. The sarcolemma receives and conducts stimuli.

Skeletal muscle cells

Diagram of skeletal muscle fiber structure

Skeletal muscle cells are the individual contractile cells within a muscle and are more usually known as muscle fibers because of their longer threadlike appearance. A single muscle such as the biceps brachii in a young adult human male contains around 253,000 muscle fibers. Skeletal muscle fibers are the only muscle cells that are multinucleated with the nuclei usually referred to as myonuclei. This occurs during myogenesis with the fusion of myoblasts each contributing a nucleus to the newly formed muscle cell or myotube. Fusion depends on muscle-specific proteins known as fusogens called myomaker and myomerger.

A striated muscle fiber contains myofibrils consisting of long protein chains of myofilaments. There are three types of myofilaments: thin, thick, and elastic that work together to produce a muscle contraction. The thin myofilaments are filaments of mostly actin and the thick filaments are of mostly myosin and they slide over each other to shorten the fiber length in a muscle contraction. The third type of myofilament is an elastic filament composed of titin, a very large protein.

In striations of muscle bands, myosin forms the dark filaments that make up the A band. Thin filaments of actin are the light filaments that make up the I band. The smallest contractile unit in the fiber is called the sarcomere which is a repeating unit within two Z bands. The sarcoplasm also contains glycogen which provides energy to the cell during heightened exercise, and myoglobin, the red pigment that stores oxygen until needed for muscular activity.

The sarcoplasmic reticulum, a specialized type of smooth endoplasmic reticulum, forms a network around each myofibril of the muscle fiber. This network is composed of groupings of two dilated end-sacs called terminal cisternae, and a single T-tubule (transverse tubule), which bores through the cell and emerge on the other side; together these three components form the triads that exist within the network of the sarcoplasmic reticulum, in which each T-tubule has two terminal cisternae on each side of it. The sarcoplasmic reticulum serves as a reservoir for calcium ions, so when an action potential spreads over the T-tubule, it signals the sarcoplasmic reticulum to release calcium ions from the gated membrane channels to stimulate muscle contraction.

In skeletal muscle, at the end of each muscle fiber, the outer layer of the sarcolemma combines with tendon fibers at the myotendinous junction. Within the muscle fiber pressed against the sarcolemma are multiply flattened nuclei; embryologically, this multinucleate condition results from multiple myoblasts fusing to produce each muscle fiber, where each myoblast contributes one nucleus.

Cardiac muscle cells

The cell membrane of a cardiac muscle cell has several specialized regions, which may include the intercalated disc, and transverse tubules. The cell membrane is covered by a lamina coat which is approximately 50  nm wide. The laminar coat is separable into two layers; the lamina densa and lamina lucida. In between these two layers can be several different types of ions, including calcium.

Cardiac muscle like the skeletal muscle is also striated and the cells contain myofibrils, myofilaments, and sarcomeres as the skeletal muscle cell. The cell membrane is anchored to the cell's cytoskeleton by anchor fibers that are approximately 10  nm wide. These are generally located at the Z lines so that they form grooves and transverse tubules emanate. In cardiac myocytes, this forms a scalloped surface.

The cytoskeleton is what the rest of the cell builds off of and has two primary purposes; the first is to stabilize the topography of the intracellular components and the second is to help control the size and shape of the cell. While the first function is important for biochemical processes, the latter is crucial in defining the surface-to-volume ratio of the cell. This heavily influences the potential electrical properties of excitable cells. Additionally, deviation from the standard shape and size of the cell can have a negative prognostic impact.

Smooth muscle cells

Smooth muscle cells are so-called because they have neither myofibrils nor sarcomeres and therefore no striations. They are found in the walls of hollow organs, including the stomach, intestines, bladder and uterus, in the walls of blood vessels, and in the tracts of the respiratory, urinary, and reproductive systems. In the eyes, the ciliary muscles dilate and contract the iris and alter the shape of the lens. In the skin, smooth muscle cells such as those of the arrector pili cause hair to stand erect in response to cold temperature or fear.

Smooth muscle cells are spindle-shaped with wide middles, and tapering ends. They have a single nucleus and range from 30 to 200 micrometers in length. This is thousands of times shorter than skeletal muscle fibers. The diameter of their cells is also much smaller which removes the need for T-tubules found in striated muscle cells. Although smooth muscle cells lack sarcomeres and myofibrils they do contain large amounts of the contractile proteins actin and myosin. Actin filaments are anchored by dense bodies (similar to the Z discs in sarcomeres) to the sarcolemma.

Development

A myoblast is an embryonic precursor cell that differentiates to give rise to the different muscle cell types. Differentiation is regulated by myogenic regulatory factors, including MyoD, Myf5, myogenin, and MRF4. GATA4 and GATA6 also play a role in myocyte differentiation.

Skeletal muscle fibers are made when myoblasts fuse together; muscle fibers therefore are cells with multiple nuclei, known as myonuclei, with each cell nucleus originating from a single myoblast. The fusion of myoblasts is specific to skeletal muscle, and not cardiac muscle or smooth muscle.

Myoblasts in skeletal muscle that do not form muscle fibers dedifferentiate back into myosatellite cells. These satellite cells remain adjacent to a skeletal muscle fiber, situated between the sarcolemma and the basement membrane of the endomysium (the connective tissue investment that divides the muscle fascicles into individual fibers). To re-activate myogenesis, the satellite cells must be stimulated to differentiate into new fibers.

Myoblasts and their derivatives, including satellite cells, can now be generated in vitro through directed differentiation of pluripotent stem cells.

Kindlin-2 plays a role in developmental elongation during myogenesis.

Function

Muscle contraction in striated muscle

Skeletal muscle contraction

When contracting, thin and thick filaments slide concerning each other by using adenosine triphosphate. This pulls the Z discs closer together in a process called the sliding filament mechanism. The contraction of all the sarcomeres results in the contraction of the whole muscle fiber. This contraction of the myocyte is triggered by the action potential over the cell membrane of the myocyte. The action potential uses transverse tubules to get from the surface to the interior of the myocyte, which is continuous within the cell membrane. Sarcoplasmic reticula are membranous bags that transverse tubules touch but remain separate from. These wrap themselves around each sarcomere and are filled with Ca2+.

Excitation of a myocyte causes depolarization at its synapses, the neuromuscular junctions, which triggers an action potential. With a singular neuromuscular junction, each muscle fiber receives input from just one somatic efferent neuron. Action potential in a somatic efferent neuron causes the release of the neurotransmitter acetylcholine.

When the acetylcholine is released it diffuses across the synapse and binds to a receptor on the sarcolemma, a term unique to muscle cells that refers to the cell membrane. This initiates an impulse that travels across the sarcolemma.

When the action potential reaches the sarcoplasmic reticulum it triggers the release of Ca2+ from the Ca2+ channels. The Ca2+ flows from the sarcoplasmic reticulum into the sarcomere with both of its filaments. This causes the filaments to start sliding and the sarcomeres to become shorter. This requires a large amount of ATP, as it is used in both the attachment and release of every myosin head. Very quickly Ca2+ is actively transported back into the sarcoplasmic reticulum, which blocks the interaction between the thin and thick filament. This in turn causes the muscle cell to relax.

There are four main types of muscle contraction: twitch, treppe, tetanus, and isometric/isotonic. Twitch contraction is the process in which a single stimulus signals a single contraction. In twitch contraction, the length of the contraction may vary depending on the size of the muscle cell. During treppe (or summation) contraction muscles do not start at maximum efficiency; instead, they achieve increased strength of contraction due to repeated stimuli. Tetanus involves a sustained contraction of muscles due to a series of rapid stimuli, which can continue until the muscles fatigue. Isometric contractions are skeletal muscle contractions that do not cause movement of the muscle. However, isotonic contractions are skeletal muscle contractions that do cause movement.

Cardiac muscle contraction

Specialized cardiomyocytes in the sinoatrial node generate electrical impulses that control the heart rate. These electrical impulses coordinate contraction throughout the remaining heart muscle via the electrical conduction system of the heart. Sinoatrial node activity is modulated, in turn, by nerve fibers of both the sympathetic and parasympathetic nervous systems. These systems act to increase and decrease, respectively, the rate of production of electrical impulses by the sinoatrial node.

Evolution

The evolutionary origin of muscle cells in animals is highly debated: One view is that muscle cells evolved once, and thus all muscle cells have a single common ancestor. Another view is that muscles cells evolved more than once, and any morphological or structural similarities are due to convergent evolution, and the development of shared genes that predate the evolution of muscle – even the mesoderm (the mesoderm is the germ layer that gives rise to muscle cells in vertebrates).

Schmid & Seipel (2005) argue that the origin of muscle cells is a monophyletic trait that occurred concurrently with the development of the digestive and nervous systems of all animals, and that this origin can be traced to a single metazoan ancestor in which muscle cells are present. They argue that molecular and morphological similarities between the muscles cells in Cnidaria and Ctenophora are similar enough to those of bilaterians that there would be one ancestor in metazoans from which muscle cells derive. In this case, Schmid & Seipel argue that the last common ancestor of Bilateria, Ctenophora and Cnidaria, was a triploblast (an organism having three germ layers), and that diploblasty, meaning an organism with two germ layers, evolved secondarily, because of their observation of the lack of mesoderm or muscle found in most cnidarians and ctenophores. By comparing the morphology of cnidarians and ctenophores to bilaterians, Schmid & Seipel were able to conclude that there were myoblast-like structures in the tentacles and gut of some species of cnidarians and the tentacles of ctenophores. Since this is a structure unique to muscle cells, these scientists determined based on the data collected by their peers that this is a marker for striated muscles similar to that observed in bilaterians. The authors also remark that the muscle cells found in cnidarians and ctenophores are often contested due to the origin of these muscle cells being the ectoderm rather than the mesoderm or mesendoderm.

The origin of true muscle cells is argued by other authors to be the endoderm portion of the mesoderm and the endoderm. However, Schmid & Seipel (2005) counter skepticism – about whether the muscle cells found in ctenophores and cnidarians are "true" muscle cells – by considering that cnidarians develop through a medusa stage and polyp stage. They note that in the hydrozoans' medusa stage, there is a layer of cells that separate from the distal side of the ectoderm, which forms the striated muscle cells in a way similar to that of the mesoderm; they call this third separated layer of cells the ectocodon. Schmid & Seipel argue that even in bilaterians, not all muscle cells are derived from the mesendoderm: Their key examples are that in both the eye muscles of vertebrates, and the muscles of spiralians, these cells derive from the ectodermal mesoderm, rather than the endodermal mesoderm. Furthermore, they argue that since myogenesis does occur in cnidarians with the help of the same molecular regulatory elements found in the specification of muscle cells in bilaterians, that there is evidence for a single origin for striated muscle.

In contrast to this argument for a single origin of muscle cells, Steinmetz, Kraus, et al. (2012) argue that molecular markers such as the myosin II protein used to determine this single origin of striated muscle predate the formation of muscle cells. They use an example of the contractile elements present in the Porifera, or sponges, that do truly lack this striated muscle containing this protein. Furthermore, Steinmetz, Kraus, et al. present evidence for a polyphyletic origin of striated muscle cell development through their analysis of morphological and molecular markers that are present in bilaterians and absent in cnidarians, ctenophores, and bilaterians. Steinmetz, Kraus, et al. showed that the traditional morphological and regulatory markers such as actin, the ability to couple myosin side chains phosphorylation to higher concentrations of the positive concentrations of calcium, and other MyHC elements are present in all metazoans not just the organisms that have been shown to have muscle cells. Thus, the usage of any of these structural or regulatory elements in determining whether or not the muscle cells of the cnidarians and ctenophores are similar enough to the muscle cells of the bilaterians to confirm a single lineage is questionable according to Steinmetz, Kraus, et al. Furthermore, they explain that the orthologues of the Myc genes that have been used to hypothesize the origin of striated muscle occurred through a gene duplication event that predates the first true muscle cells (meaning striated muscle), and they show that the Myc genes are present in the sponges that have contractile elements but no true muscle cells. Steinmetz, Kraus, et al. also showed that the localization of this duplicated set of genes that serve both the function of facilitating the formation of striated muscle genes, and cell regulation and movement genes, were already separated into striated much and non-muscle MHC. This separation of the duplicated set of genes is shown through the localization of the striated much to the contractile vacuole in sponges, while the non-muscle much was more diffusely expressed during developmental cell shape and change. Steinmetz, Kraus, et al. found a similar pattern of localization in cnidarians except with the cnidarian N. vectensis having this striated muscle marker present in the smooth muscle of the digestive tract. Thus, they argue that the pleisiomorphic trait of the separated orthologues of much cannot be used to determine the monophylogeny of muscle, and additionally argue that the presence of a striated muscle marker in the smooth muscle of this cnidarian shows a fundamental different mechanism of muscle cell development and structure in cnidarians.

Steinmetz, Kraus, et al. (2012) further argue for multiple origins of striated muscle in the metazoans by explaining that a key set of genes used to form the troponin complex for muscle regulation and formation in bilaterians is missing from the cnidarians and ctenophores, and 47 structural and regulatory proteins observed, Steinmetz, Kraus, et al. were not able to find even on unique striated muscle cell protein that was expressed in both cnidarians and bilaterians. Furthermore, the Z-disc seemed to have evolved differently even within bilaterians and there is a great deal of diversity of proteins developed even between this clade, showing a large degree of radiation for muscle cells. Through this divergence of the Z-disc, Steinmetz, Kraus, et al. argue that there are only four common protein components that were present in all bilaterians muscle ancestors and that of these for necessary Z-disc components only an actin protein that they have already argued is an uninformative marker through its pleisiomorphic state is present in cnidarians. Through further molecular marker testing, Steinmetz et al. observe that non-bilaterians lack many regulatory and structural components necessary for bilaterians muscle formation and do not find any unique set of proteins to both bilaterians and cnidarians and ctenophores that are not present in earlier, more primitive animals such as the sponges and amoebozoans. Through this analysis, the authors conclude that due to the lack of elements that bilaterian muscles are dependent on for structure and usage, nonbilaterian muscles must be of a different origin with a different set of regulatory and structural proteins.

In another take on the argument, Andrikou & Arnone (2015) use the newly available data on gene regulatory networks to look at how the hierarchy of genes and morphogens and another mechanism of tissue specification diverge and are similar among early deuterostomes and protostomes. By understanding not only what genes are present in all bilaterians but also the time and place of deployment of these genes, Andrikou & Arnone discuss a deeper understanding of the evolution of myogenesis.

In their paper, Andrikou & Arnone (2015) argue that to truly understand the evolution of muscle cells the function of transcriptional regulators must be understood in the context of other external and internal interactions. Through their analysis, Andrikou & Arnone found that there were conserved orthologues of the gene regulatory network in both invertebrate bilaterians and cnidarians. They argue that having this common, general regulatory circuit allowed for a high degree of divergence from a single well-functioning network. Andrikou & Arnone found that the orthologues of genes found in vertebrates had been changed through different types of structural mutations in the invertebrate deuterostomes and protostomes, and they argue that these structural changes in the genes allowed for a large divergence of muscle function and muscle formation in these species. Andrikou & Arnone were able to recognize not only any difference due to mutation in the genes found in vertebrates and invertebrates but also the integration of species-specific genes that could also cause divergence from the original gene regulatory network function. Thus, although a common muscle patterning system has been determined, they argue that this could be due to a more ancestral gene regulatory network being coopted several times across lineages with additional genes and mutations causing very divergent development of muscles. Thus it seems that the myogenic patterning framework may be an ancestral trait. However, Andrikou & Arnone explain that the basic muscle patterning structure must also be considered in combination with the cis regulatory elements present at different times during development. In contrast with the high level of gene family apparatuses structure, Andrikou and Arnone found that the cis-regulatory elements were not well conserved both in time and place in the network which could show a large degree of divergence in the formation of muscle cells. Through this analysis, it seems that the myogenic GRN is an ancestral GRN with actual changes in myogenic function and structure possibly being linked to later coopts of genes at different times and places.

Evolutionarily, specialized forms of skeletal and cardiac muscles predated the divergence of the vertebrate / arthropod evolutionary line. This indicates that these types of muscle developed in a common ancestor sometime before 700 million years ago (mya). Vertebrate smooth muscle was found to have evolved independently from the skeletal and cardiac muscle types.

Invertebrate muscle cell types

The properties used for distinguishing fast, intermediate, and slow muscle fibers can be different for invertebrate flight and jump muscle. To further complicate this classification scheme, the mitochondrial content, and other morphological properties within a muscle fiber, can change in a tsetse fly with exercise and age.

Race and sports

From Wikipedia, the free encyclopedia

Issues related to race and sports have been examined by scholars for a long time. Among these issues are racial discrimination in sports as well as the observation that there are overrepresentations and underrepresentations of different races in different sports.

Participation and performance disparities

Sprinting

In 1991, Namibian (formerly South-West Africa) Frankie Fredericks became the first sub-10-second 100 metres runner of non-West African heritage and in 2003 Australia's Patrick Johnson (who has Irish and Indigenous Australian heritage) became the first to achieve the feat without an African background.

In 2010, Frenchman Christophe Lemaitre became the first white European under ten seconds, (although Poland's Marian Woronin had unofficially surpassed the barrier with a time of 9.992 seconds in 1984). In 2011, Zimbabwean Ngonidzashe Makusha became the 76th man to break the barrier, yet only the fourth man not of West African descent. No sprinter from South Asia, East Africa or North Africa has officially achieved this feat. In 2015 Su Bingtian of China became the first ethnic East Asian athlete to officially break the 10 second barrier and British athlete Adam Gemili—who is of mixed Iranian and Moroccan descent—became the first athlete with either North African or Middle Eastern heritage to break the ten second barrier. Before the 2004 Athens Games, 494 of the top 500 times for the 100m were held by sprinters who were of West African descent.

Olympic 100 m medallists in the early phase of the Modern Olympic Games were principally white, Western sprinters of European descent, largely reflecting the euro-centric make up of the nations that took part and the ideological environment of racial segregation at the time. As the Olympic competition began to attract wider international participation, athletes with African heritage began to reach and eventually dominate the 100 m Olympic podium, particularly African-Americans and Afro-Caribbeans.

Eddie Tolan became the first non-white winner of the event in 1932 and this signified the start of a prolonged period of success by black male sprinters; since 1932 only five men's Olympic champions in the event have not had significant African heritage. The women's event was dominated by runners of European descent until Wilma Rudolph won the title in 1960. Soviet and German women returned to the podium in the period from 1972 to 1980, but since then African-American and Jamaican women have won the great majority of 100 m medals. Dominance in the men's event has been particularly pronounced from 1984 to 2016, during which time in a span of almost 40 years all the men's Olympic 100 m finalists have been of African heritage.

In the 2020 Olympics, Chinese sprinter Su Bingtian ran 9.83 in his semi-final heat and became the first athlete without African heritage to run sub-9.90 or sub-9.85 and the first athlete without African heritage to reach the final since 1980 within the span of 40 years, setting the fastest 60 metres split record en route. 9.83 is also the second fastest semi-final time and made him the fifth fastest man in the history of 100 metres at the Olympics behind Usain Bolt, Yohan Blake, Justin Gatlin and Marcel Jacobs.

Endurance running

Many Nilotic groups also excel in long and middle distance running. Jon Entine has argued that this sporting prowess stems from their exceptional running economy. This in turn is a function of slim body morphology and slender legs, a preponderance of slow twitch muscle fibers, a low heart rate gained from living at high-altitude, as well as a culture of running to school from a young age. A study by Pitsiladis et al. (2006) questioning 404 elite distance runners from Kenya found that 76% of the international-class respondents hailed from the Kalenjin ethnic group and that 79% spoke a Nilotic language.

Joseph L. Graves argues that Kenyan athletes from the African Great Lakes region who have done well in long distance running all have come from high-altitude areas, whereas those from low-altitude areas do not perform particularly well. He also argues that Koreans and Ecuadorians from high-altitude areas compete well with Kenyans in long-distance races. According to Graves, this suggests that it is the fact of having trained in a high altitude, combined with possible local level physiological adaptations to high-altitude environments that is behind the success in long distance running, not race.

Graves also argues that while it is superficially true that most of the world record-holders in the 100-meter dash are of West African heritage, they also all have partial genetic heritage from Europe and Native America, they have also all trained outside of West Africa, and West African nations have not trained any top-level runners. Graves says these factors make it impossible to say to which degree the success is best attributed to genetic or to environmental factors. But later Graves found it possible: "Endurance runners are more likely to come from East Africa and sprinters from West Africa. That’s a fact. Genes play a major role in this.”

Views in the United States

Various individuals, including scholars and sportswriters, have commented on the apparent over-representations and under-representations of different races in different sports. African Americans accounted for 75% of players in the National Basketball Association (NBA) near the end of 2008. According to the latest National Consortium for Academics and Sports equality report card, 65% of National Football League players were African Americans. However, in 2008, about 8.5% of Major League Baseball players were African American (who make up about 13% of the US population), and 29.1% were Hispanics of any race (compared with about 16% of the US population). In 2020, less than 5% of the National Hockey League (NHL) players are black or of mixed black heritage.

NCAA sports have mirrored the trends present in American professional sports. During the 2005–2006 season, black males comprised 46.9 percent of NCAA Football Bowl Subdivision (FBS) and 58.9 percent of NCAA Division I basketball. The NCAA statistics show a strong correlation between percentage of black athletes within a sport and the revenue generated by that sport. For example, University of North Carolina's 2007–2008 men's basketball team (the team was 59% black relative to the 3.7% black population of the institution as a whole) generated $17,215,199 in revenue, which comprised 30 percent of the school's athletic revenue for the year. Given NCAA rules prohibiting the payment of players, some have come to see the structure of NCAA athletics as exploitative of college athletes. Some believe that since black athletes comprise a high percentage of athletes in high revenue college sports (FBS football and Division I Men's basketball), they are therefore the biggest losers in this arrangement. Billy Hawkins argues that "the control over the Black male's body and profiting off its physical expenditure is in the hands of White males." His position refers to a very high percentage of Division I universities controlled by white administrations that prosper greatly from the free labor produced by the revenue sports that are heavily populated by black athletes. This claim is substantiated by statistics, such as the 2005–2006 NCAA Division I men's basketball tournament in which games started, and minutes played for black athletes were over double that of their white counterparts, with 68.7 percent of scoring in the tournament coming from black players.

Despite the frequency of such speculation, suggestions of biological differences in athletic ability between racial groups are considered unscientific.

"Black athletic superiority"

"Black athletic superiority" is the theory that black people possess certain traits that are acquired through genetic and/or environmental factors that allow them to excel over other races in athletic competition. Whites are more likely to hold these views; however, some blacks and other racial groups do as well. A 1991 poll in the United States indicated that half of the respondents agreed with the belief that "blacks have more natural physical ability".

Various hypotheses regarding racial differences of black and white people and their possible effect on sports performance have been put forth since the later part of the nineteenth century by professionals in many various fields. In the United States, attention to the subject faded over the first two decades of the twentieth century as black athletes were eliminated from white organized sport and segregated to compete among themselves on their own amateur and professional teams. Interest in the subject was renewed after the 1932 Summer Olympics in Los Angeles and Jesse Owens's record-breaking performances at the 1935 Big Ten Track Championships. Regarding Jesse Owens's impressive four-gold medal performance in the following 1936 Olympics, the then U.S head coach remarked that "The Negro excels. It was not long ago that his ability to sprint and jump was a life-and-death matter to him in the jungle. His muscles are pliable, and his easy going disposition is a valuable aid to the mental and physical relaxation that a runner and jumper must have."

In 1971, African-American sociologist Harry Edwards wrote: "The myth of the black male's racially determined, inherent physical and athletic superiority over the white male, rivals the myth of black sexual superiority in antiquity." Later in 2003, the JBHE Foundation published an article in The Journal of Blacks in Higher Education, where they pushed back against this idea of a "black gene" leading to black superiority in athletics, a concept referred to here as "Racist Theory". The JBHE contended that "If there is a 'black gene' that leads to athletic prowess, why then do African Americans, 90 percent of whom have at least one white ancestor, outperform blacks from African nations in every sport except long distance running?"

"East Asian athletic views"

In the United States, East Asians are stereotyped as being physically and athletically inferior to other races. This has led to much discrimination in the recruitment process of professional American sports, which contributes to Asian American athletes being highly underrepresented in the majority of professional sports teams (a fact that has been noted by many sources). Professional basketball player Jeremy Lin believed that one of the reasons why he wasn't drafted by an NBA team was his race. This belief has been reiterated by sports writer Sean Gregory of Time magazine and NBA commissioner David Stern. In 2012, despite making up 6% of nation's population Asian American athletes only represented 2% of the NFL, 1.9% of the MLB and less than 1% of the NBA and NHL. Brandon Yip was the only player of Chinese descent playing professional hockey in the NHL in 2011. Basketball is a sport that noted for the fact that it has one of the lowest numbers of Asian athletes. This is despite the fact that the sport's color barrier was broken by Wataru Misaka in 1947, an Asian American athlete who was the first American racial minority to play in the NBA.

In American sports, there has been a higher representation of Asian American athletes who are of mixed racial heritage in comparison to those of full racial heritage such as former football player Roman Gabriel who was the first Asian-American to start as an NFL quarterback. Another fact to note is that a majority of Asian American athletes who are currently drafted/recruited to compete professionally tend to be in sports that require little to no contact.

Chinese views

The idea among Chinese people that "genetic differences" cause Asian athletes to be "slower at sprinting" than their American, African or European rivals is "widely accepted". The People's Daily, a Chinese newspaper, wrote that Chinese are "suited" to sports that draw upon "agility and technique", such as table tennis, badminton, diving, and gymnastics. The newspaper said that Chinese people have "congenital shortcomings" and "genetic differences" that meant that they are disadvantaged at "purely athletic events" when competing against "black and white athletes". The success of hurdler Liu Xiang was explained by the hurdles event requiring technique which fit with the stereotype that Chinese are disciplined and intelligent. However, the recent successes of Chinese lightweight and middleweight weightlifters contradicts conventional belief, as weightlifting is one of the sports that demonstrates raw strength and explosive power best. Chinese and Korean professional weightlifters are especially overrepresented in olympic weightlifting, dominating international competitions such as weightlifting at the Summer Olympics and the International Weightlifting Federation.

Li Aidong, a researcher with the China Institute of Sports Science, said that sports coaches believed that Chinese athletes could have success in long jumping, high jumping and race walking. However, Li doubted that Chinese could compete in "pure sprinting", although there did not exist any "credible scientific studies" which supported the idea that "Asians" were disadvantaged in "sprinting". Professional sprinters Su Bingtian of China and Yoshihide Kiryū of Japan have contradicted this view of East Asians struggling to achieve quick footspeed, as both have broken the 10-second barrier in the 100 m and Su has ranked in the top five all-time fastest runners over 60 metres.

Explanations for participation and performance disparities

Physiological factors

A 1994 examination of 32 English sport/exercise science textbooks found that seven suggested that there are biophysical differences due to race that might explain differences in sports performance, one expressed caution with the idea, and the other 24 did not mention the issue.

Socioeconomic factors

In Stuck in the Shallow End: Education, Race, and Computing, UCLA researcher Jane Margolis outlines the history of segregation in swimming in the United States to show how people of colour have been affected up to the present day by inadequate access to swimming facilities and lessons. Margolis asserts that physiological differences between ethnic groups are relatively minor and says: "In most cases of segregation, stereotypes and belief systems about different ethnic gender groups' genetic make-up and physical abilities (and inabilities) emerge to rationalize unequal access and resulting disparities." According to Margolis, views regarding "buoyancy problems" of African Americans are merely part of folklore which have been passed down from generation to generation. Joan Ferrante, a professor of sociology at Northern Kentucky University, suggests that geographic location, financial resources, and the influence of parents, peers, and role models are involved in channeling individuals of certain races towards particular sports and away from others.

Haplogroup inheritance

Elite athletic capacity has also been correlated with differing patterns of haplogroup inheritance. Moran et al. (2004) observed that among Y-DNA (paternal) clades borne by elite endurance athletes in Ethiopia, the E*, E3*, K*(xP), and J*(xJ2) are positively correlated with elite athletic endurance performance, whereas the haplogroup E3b1 is significantly less frequent among the elite endurance athletes.

Citing haplogroup data from various previous studies, Ahmetov and Fedotovskaya (2012) report that the mtDNA (maternal) haplogroups I, H, L0, M*, G1, N9, and V have been positively correlated with elite athletic endurance performance, whereas the mtDNA haplogroups L3*, B, K, J2, and T are negatively correlated with athletic endurance performance. Japanese sprinters were also found to have a higher distribution of the mtDNA F.

Racial prejudices, discrimination, segregation, and integration

The baseball color line, which included separate Negro league baseball, was one example of racial segregation in the United States.

In the United States, a study found that a form of racial discrimination exists in NBA basketball, as white players received higher salaries than do blacks related to actual performance. Funk says this may be due to viewer discrimination. Viewership increases when there is greater participation by white players, which means higher advertising incomes. This explains much of the salary gap.

Researchers have looked at other evidence for sports consumer discrimination. One method is comparing the price of sports memorabilia, such as baseball cards. Another is looking at fan voting for all-star teams. Still another is looking at willingness to attend sporting events. The evidence is mixed, with some studies finding bias against blacks and others not. A bias, if it exists, may be diminishing and possibly disappearing, according to a study on fan voting for baseball all-star teams.

Major League Baseball

Jackie Robinson was the first African American to play a major league game on April 15, 1947. Jackie loved the sport of baseball but that wasn't his only goal to make the majors. He wanted to make a way for more African Americans to join the league. However, with struggles of people being racist in the stands, players spouting off racial slang words to other players or fans, etc. Jackie wasn't discouraged to the hate as he was not only one of the best African Americans to play the game but one of the best in the history of baseball.

Blacks in American baseball
Year Major leagues Population Ratio
1945 2% 10% 1:5
1959 17% 11% 3:2
1975 27% 11% 5:2
1995 19% 12% 3:2

The under-representation of Blacks in U.S. baseball ended during the early years of the civil rights movement. The representation of different races in Major League Baseball has been increasing since 1947 according to Mark Armour and Daniel R Levitt of the Society for American Baseball Research. According to their research, African American representation reached its peak in 1984 when it reached 18.4%. However, the African American representation has been steadily decreasing since that point. As of 2016, the African American representation was down to 6.7%.

According to Armour and Levitt, the Latino representation has been steadily increasing since 1947. That year, the representation was only at 0.7%. Since that time, the Latino representation in baseball has increased substantially. As of 2016, the Latino representation was at 27.4%.

Asian American representation in baseball has been much less abundant throughout the game's history according to Armour and Levitt. Their representation in the Major League did not get over 1% until 1999 when their representation was at 1.2%. While the representation is increasing, it is doing so significantly slower than the other races. As of 2016 Asian American representation was only at 2.1%, a small increase from 1999.

According to Armour and Levitt, Whites make up the largest portion of the different races represented in the Major League. However, their representation has been steadily declining as the African American, Asian, and Latino representation has been steadily on the rise. The Society for American Baseball research shows that white representation was at 98.3% in 1947. Since then, representation has decreased to 63.7% in 2016.

In a journal titled Using Giddens's Structuration Theory to Examine the Waning Participation of African Americans in Baseball, it says "Numerous studies have shown that African-American youths are more likely than Whites to be encouraged and even directed to play basketball over other sports."

National Basketball Association

Although Japanese-American Wataru Misaka broke the National Basketball Association's color barrier in the 1947–48 season when he played for the New York Knicks, 1950 is recognized as the year the NBA integrated. That year African-American players joined several teams; they included Chuck Cooper with the Boston Celtics, Nat "Sweetwater" Clifton with the New York Knicks, and Earl Lloyd with the Washington Bullets.

In another example from an interview with NBA Hall of Famer Kareem Abdul-Jabbar he states "For people of color, professional sports has always been a mirror of America's attitude toward race: as long as Black players were restricted from taking the field, then the rest of Black Americans would never truly be considered equal, meaning they would not be given equal educational or employment opportunities." Jabbar played in the NBA for 20 seasons dating back to 1969.

National Football League

Black players participated in the National Football League from its inception in 1920; however, there were no African-American players from 1933 to 1946. There is a great deal of speculation as to why this "gentleman's agreement", as it came to be called, was implemented during this era. Some argue that it was purely because of the Great Depression. Jobs were difficult to come by, and thus race relations became increasingly strained as African-Americans, and other minorities, became perceived as "threats". Finally, in 1946, the Los Angeles Rams broke this unofficial "agreement" and drafted Kenny Washington along with Woody Strode in the same year. The final NFL team to break this agreement was the Washington Redskins, who signed Bobby Mitchell in 1962.

In October 2018, George Taliaferro, the first African American who played in the NFL died at the age of 91. While George was the first African American drafted to play in the NFL, the first African American would not be drafted as the Quarterback until 1953, when Willie Thrower was drafted to play with the Chicago Bears. It wouldn't be for another 14 years, 1967, until the first African American, Emlen Tunnell, would be elected for the NFL Hall of Fame.

National Hockey League

On November 16, 1926, Native American Taffy Abel joined the New York Rangers, breaking the NHL color barrier and making history as the first ever Native American to play in the National Hockey League since its founding in 1917. On January 18, 1958, Willie O'Ree joined the Boston Bruins in a game against the Montreal Canadiens, making history as the first ever black person to play in the National Hockey League.  Some 16 years later, Mike Marson became the second black player to join the league with his expansion to the Washington Capitals. Decades later, a 2020 analysis revealed that people of color still comprise less than 5% of players in the National Hockey League and that out of 377 head coaches hired over 102 years, only one has been black.

Though black people are evidently under-represented in the National Hockey League, this is not at all reflective of their involvement in the sport and its development. In 1895–22 years before the establishment of the National Hockey League—the Colored Hockey League took form in Nova Scotia, Canada. This was hockey's first ever organized league, and at its peak contained hundreds of players throughout more than a dozen teams. The season ran from late January to early March as they were only allowed access to the ice rinks when the white-only leagues finished their seasons, leaving the Colored Hockey League with the worst of the ice conditions and subsequently with a much shorter season. Political and racial tensions forced the league to disintegrate in 1905 as they were no longer allowed to use arenas at all, regardless of the time of year. In 1921, the league re-formed on a smaller scale with just three teams but struggled to gain and keep traction. By the mid-1930s, the National Hockey League had become hugely popular while the Colored Hockey League had disappeared altogether.

Despite the many barriers imposed on the Colored Hockey League, they were reportedly just as competitive as the white-only leagues while demonstrating a faster and more aggressive style of play and making revolutionary contributions to the sport. The illustrious slapshot, for example, was invented by Colored Hockey League star Eddie Martin and later popularized by white players in the National Hockey League. Additionally, Henry "Braces" Franklyn was the first goalie to go down on to the ice to make saves; this 'butterfly style' was also popularized many years later by white players and remains a staple of the modern game.

Professional Golfers Association

In 1961, the "Caucasians only" clause was struck from the Professional Golfers' Association of America constitution.

Throughout the game's history, golf has not included many African-American players, and they were often denied the opportunity to golf. However, many found a way to play the game anyway. According to an article by the African-American Registry titled African-Americans and Golf, a Brief History, "the Professional Golf Association of America (PGA) fought hard and until 1961, successfully maintained its all-white status. Black golfers (then) created their own organization of touring professionals."

Tiger Woods has had a major impact on the game of golf, especially among minorities. The article, African-Americans and Golf, a Brief History, states "With the ascent of Tiger Woods and his golf game comes an increased interest and participation from young minorities in the game. He himself envisions this impacting in the next ten years as they come of age and develop physically as well." Woods hopes minority participation will continue to increase in the future.

The research surrounding descriptions employed about White and Black athletes in the media and how the stereotypes of Black athletes has affected Tiger Woods in a majority white sport, because Tiger Woods was the only Black golfer on the PGA tour, he received different comments related to Black stereotypes that the other golfers on the tour did not.

African American participation in golf has been increasing. In a journal titled African American Culture and Physical Skill Development Programs: The Effect on Golf after Tiger Woods, it says "Smith (1997) reported data from a National Golf Foundation (NDF) study in the United States indicating there are 676,000 African-American golfers (2.7% of the 24.7 million golfers)."

As African-American participation increased, Asian participation in professional golf has also increased. According to an article by Golfweek titled Record Number of Asian Golfers Compete for Masters Glory, there were 10 golfers which was a tournament record.

According to the article Where are all the black golfers? Nearly two decades after Tiger Woods' arrival, golf still struggles to attract minorities, As of 2013 there were 25.7 million golfers: this was composed of 20.3 million whites, 3.1 million Hispanics, 1.3 million African-Americans, and 1 million Asian-Americans. The lack of diversity is still very apparent in golf today.

Positions of power: coaching and administration

Referring to quarterbacks, head coaches, and athletic directors, Kenneth L. Shropshire of the Wharton School of the University of Pennsylvania has described the number of African Americans in "positions of power" as "woefully low". In 2000, 78% of players in the NBA were Black, but only 33% of NBA officials were minorities. The lack of minorities in positions of leadership has been attributed to racial stereotypes as well "old boy networks" and white administrators networking within their own race. In 2003, the NFL implemented the Rooney Rule, requiring teams searching for a new head coach to interview at least one minority candidate.

With an inadequate number of minorities in executive positions in the NFL, the NFL decided to revise the Rooney Rule to include teams to interview minorities for general manager positions. There has been backlash on how effective this rule has been and if there needs to be more revisions to this rule. As of 2022, there are only six minority head coaches in the NFL: Lovie Smith, Mike Tomlin, Ron Rivera, Robert Saleh, Todd Bowles, and Mike McDaniel. Because of racial discrimination, which AAP News & Journal defines as, "a form of social inequality that includes experiences resulting from legal and nonlegal systems of discrimination", it has resulted in unequal outcomes and a power struggle. A vast majority of the representation of minority coaches are held at positional or assistant coaches. With a lot of people [minorities] competing for head coaching positions with only a limited supply, it allows the very few minority head coaches to get handsomely salaries while the rest get average or low pay. Not only are finances an issue, the talent that is being presented is ultimately looked over because minorities coaches are not being hired and the NFL is meeting their status quo, of at least interviewing minorities for head coaching and general manager positions. Social networks also play a big role in how coaches are hired.

The power dynamics between the owners and players in the NFL has created racial inequality between the two groups. 30 owners are white while only two owners are of color (one is from Pakistan and one is Asian American). Richard Roth, sports attorney who has represented Peyton Manning, claimed, "22 of the teams in the NFL have been owned by the same person or family for at least 20 years". Dr. Richard Lapchick, director of the Institute for Diversity and Ethics in Sports, claimed, "Who owners invite into their fraternity-and its overwhelmingly a fraternity-is self-selective". Owners of teams must be very wealthy as teams "Cost upwards of $1B". Due to wealth inequality in the United States, there are few black billionaires who could be potential candidates. Furthermore, from a social class standpoint, it is very difficult for there to be a black owner as "very few black people are part of these billionaires' boys' clubs".

Many of the racial problems shown in sports are present because of the lack of diversity in ownership. The predominant presence of white male owners in sports drives a wedge between members of the organization. The narrative portrayed by ownership in sports paints the same picture of slave and owner from 400 years ago. NBA player Draymond Green ignited debates on the relationship between team ownership and players. In 2017, Green stated that the NBA should really consider the term "owner" and its usage dating back to chattel slavery, considering the majority of NBA players are black and nearly all team ownership is white. This has been a fact virtually the entire history of sports organizations. In 1994, Black people accounted for 80% of the NFL players, 65% of the NBA players, and 18% of the MLB players, but less than 10% of team ownership. 25 years later, the percentage of black athletes and team owners has not changed much with Black people accounting for 70% of the NFL players, 81% of the NBA players, and 8% of the MLB players. Team ownership is still below 10%. However, one thing that changed with time is the term for ownership in the NBA: NBA commissioner Adam Silver declared in June 2019 that the organization will no longer use the term "owner" and will now refer to owners as governors and partial owners as alternate governors.

Aside from a lack of black owners, owners make hundreds of times what the players make. This is similar to the NFL disparity between owners and the players. According to a report by the Green Bay Packers, the NFL earned $7,808,000 from TV deals, and split it among its 32 teams evenly. This means that each NFL owner "made $244m last year in 2016". By contrast, the "average NFL player made $2.1m in 2015". The owners of these teams are making hundreds of times what the players are. This is similar to the difference in pay between CEOs and average workers of corporations. Professor Pfeffer, a social inequality professor at the University of Michigan, claimed, "CEOs make more than 350 times what the average worker makes". The work of the owners is not hundreds of times more valuable than that of the players. However, it is the power dynamics and politics of the league structure that allow owners to make so much more.

Similar to the discrepancy between participation and leadership of blacks in American professional sports leagues, NCAA sports also have had a low percentage of administrators and coaches relative to the number of athletes. For example, during the 2005–2006 academic year, high revenue NCAA sports (basketball and football) had 51 percent black student athletes, whereas only 17 percent of head coaches in the same high revenue sports were black Also, in the same 2005–2006 year, only 5.5 percent of athletic directors at Division I "PWIs" (Primarily White Institutions), were black. Terry Bowden, a notable white Division I football coach, suggests that the reason many university presidents will not hire black coaches is "because they are worried about how alumni and donors will react." Bowden also refers to the "untapped talent" existing within the ranks of assistant coaches in Division I football. The data backs up this claim, with 26.9 percent of Division I assistant coaches during the 2005-06 year in men's revenue sports being black, a notably higher percentage than of head coaches. In terms of administrative positions, they have been concentrated largely in the hands of whites. As recently as 2009, 92.5 percent of university presidents in the FBS were white, 87.5 percent of athletic directors were white, and 100 percent of the conference commissioners were white. Despite these statistics, black head coaches have become more prevalent at the FBS level. As of 2012, there are now 15 black head coaches in FBS football, including now 3 in the SEC, a conference that did not hire its first black head coach until 2003.

Segregated seating

In 1960, the Houston Oilers implemented a policy at Jeppesen Stadium to segregate the black fans from the white fans. Clem Daniels, Art Powell, Bo Roberson, and Fred Williamson of the Oakland Raiders refused to play in a stadium that had segregated seating. The 1963 game against the New York Jets was relocated to a different stadium.

Mascot controversies

The use of Native American names and imagery for sport mascots or in franchise memorabilia is an issue of ongoing discussion and controversy in American sports, as some Native American representatives have objected to such use without explicit negotiation and permission.

Washington Redskins

In July 2020, due to mounting pressure from FedEx, who owned the naming rights of their stadium and dozens of shareholders, the Washington Redskins changed their team name to the Washington Football Team. The name was considered racist by many Native American groups. In 2022, they rebranded as the Washington Commanders.

Controversy within The Atlanta Hawks

The Atlanta Hawks has had multiple cases where racial discrimination has become an issue with the organization. In 2012 Bruce Levenson, majority ownership holder in the Atlanta Hawks NBA franchise, gave an evaluation in an email to other administration on the progress of the Atlanta Hawks game operations. In the email, Levenson states originally that game operations was not a concern but is now due to the lack of a season ticket base caused by the demographics of attendants at games and those involved with game operations. Levenson claims he was told because white males around 35–55 years of age and corporations are not the target of all aspects of game operations season tickets would not sell. When pressed for answers no one would not give Levenson any further assistance figuring out the issue. It was then he noticed 70% black attendees at games, black cheerleaders at the games, the music was hip-hop, customers at the arena bars were 90% black, few fathers and sons, and the concerts after games were either hip-hop or gospel.

Despite the email being sent to staff in 2012 it was not revealed until in an investigation of a second incident that included racist remarks in regards to Luol Deng (a British NBA player born in what is now South Sudan). In 2014 Danny Ferry was the President of the Atlanta Hawks franchise. In a scouting report on Luol Deng he stated that Deng displayed good traits on the outside but despite seems like a good person he's an African. Ferry goes on to compare Deng to "African store front that looks great but there's black market section in the back".

These problematic statements by both Danny Ferry and Bruce Levenson became the driving force behind the sell of the Atlanta Hawks.The Atlanta Hawks would be bought for approximately $730 – 850 million by Tony Ressler. Due to being overshadowed by a racial incident between Donald Sterling and the Los Angeles Clippers, the Hawks organization did not receive much publicity.

Promoting racial harmony and breaking stereotypes

Racial differences in the NFL are also evident between player positions. According to an Undefeated article, all positions have remained strongly overrepresented by African American players in the period between 1999 and 2014, with African Americans outnumbering white Americans in several positions. However, this effect has been less pronounced for the center and quarterback positions: in 1999, the percentage of white players in the center position was 75% compared to 20% for African Americans, while the percentage of white players in the quarterback position was 81% compared to 18% for African American; though white Americans outnumbered African Americans in these positions, the percentages nonetheless showed significant overrepresentation of African Americans (~13% of the total population of the US) among both center and quarterback players compared to white Americans (~82% of the total population). In 2014, the center position showed more proportionate representation―with 81% being white and 16% African American―while the number of white quarterback players had decreased slightly within the same time frame (coinciding with a 1% increase in black quarterbacks). A study by the University of Colorado examining racial stereotypes towards NFL quarterbacks found that "black participants stereotyped both races more strongly...suggesting that black players may not believe they are cut out to be a professional quarterback". The study goes on to say that, "the terms physical strength and natural ability were more associated with the black quarterbacks while leadership and intelligence was more associated with white quarterbacks". These biases are thought to reflect how football players are viewed by the general populace, and ostensibly have an impact on perceptions among adolescents as well.

According to William Jeynes, a professor of education at California State University, Long Beach, the gathering at the first Thanksgiving in the United States was an attempt to create racial harmony through games and sporting contests that included running, shooting and wrestling. Huping Ling, a professor of history at Truman State University, has asserted that the participation of Chinese students in sports helped break local stereotypes in the St. Louis area during the 1920s. This history of racial tension in the competition between whites and minority groups shows an attempt to prove the humanity, equality, and even occasionally their superiority on the playing field. By doing so, groups of minorities hoped that sports would serve as a source for racial pride that would eventually lead to upward social mobility. However, as early as 1984, criticism has been levied against these ideas. Sports sociologist Harry Edwards openly criticized African Americans as being "co-conspirators" in their own children's exploitation by the white dominated sports establishment. Edwards asserted that stereotypes such as the “dumb jocks” were not born but rather socially created and fuelled by low expectations, their communities, and educational institutions that overly encourage athletic persists. Despite the perception of a white dominated sports establishment, research has shown that there is greater emphasis on sports as a potential career path in the African American community compared to the White community. Edwards continued by arguing that placing so much emphasis on sports achievement as a way for minority groups, specifically referring to African Americans, to achieve some level of prominence is de-emphasizing the importance of intellectual pursuits. John Hoberman, in Darwin’s Athletes: How Sport Has Damaged Black America and Preserved the Myth of Race, suggest that this fixation on the importance of athletic ability in the African American community has steered many youth away from more realistic occupational pursuits. He suggests that this idea is further reinforcing the concept of innate black athletic superiority.  Despite the conflicting perceptions of sports as a harmonizing instrument, many researchers still believe that not much has changed to alleviate the racially tense landscape many believe to be inherent in current day society.

Black Women + Bobsledding

Bobsledding has much representation for Black women. At the 2018 Winter Olympics, Nigerian and Jamaican bobsled teams debuted. The United States, Britain, Canada, and Germany also have Black women compete in bobsledding at the Olympic level. The high diversity is somewhat due to bobsledding recruiting athletes from other sports, especially track.

Black women who have competed in bobsled include: Vonetta Flowers, Elana Meyers Taylor, Lauryn Williams, and Sylvia Hoffman.

Racial activism in American professional sports

Racial activism has been found in many of professional sports leagues such as the National Basketball Association and the National Football League.

National Basketball Association

Following the emergence of the Trayvon Martin case, NBA players including LeBron James, Dywane Wade, Chris Bosh, and other Miami Heat players at the time posed for a picture in hoodies, the outfit that Trayvon Martin was wearing when killed. In December 2014, LeBron James and other Cleveland Cavaliers including Kyrie Irving wore black t-shirts featuring the quote "I CANT BREATHE" following the death of Eric Garner who was put in a choke hold by a New York police officer. Since then, LeBron James has been in public disputes Via Twitter and Instagram, shaming Donald Trump and news analyst Laura Ingraham who openly told LeBron James to "shut up and dribble", suggesting that LeBron is only good for his athletic abilities. LeBron then went and turned that slogan "Shut up and dribble" into the Title of his Showtime Series that aired in October 2018. The show focuses on athletes who are shifting the narrative of what it means to be a black athlete in the sense that nowadays more and more athletes are speaking up on political and racial topics going on in the United States.

National Football League

In a 2016 pre-season game against the San Diego Chargers, Colin Kaepernick, a quarterback for the San Francisco 49ers, chose to kneel instead of standing in solidarity with his teammates for the National Anthem. He did this to raise awareness for victims of police brutality and oppression of minorities in America. Many people believe Kaepernick is a hero for raising awareness for important social issues. However, his actions caused a massive backlash by fans and the media who decried him for acting anti American and disrespecting American troops. Furthermore, players from other teams began to kneel instead of stand with the national anthem. When questioned by the media, he claimed, "I am not going to stand up to show pride in a flag for a country that oppresses black people and people of color." He continued, "If they take football away, my endorsements from me, I know that I stood up for what is right." According to NFL policy, "There is no rule saying players must stand during the national anthem".

Kaepernick's act inspired many other players to also kneel during the national anthem. Bob McNair, owner of the Houston Texans, claimed, "They can't have the inmates running the prison" during a meeting with owners and no current players. After the meeting finished, Troy Vincent, former cornerback for the Miami Dolphins, claimed, "In all my years of playing in the NFL, I have been called every name in the book, including the N-word-but never felt like an inmate". Many players took to social media to protest the racist rhetoric of Bob McNair. Richard Sherman tweeted in response, "I can appreciate ppl being candid. Don't apologize! You meant what you said. Showing true colors allows ppl to see you for who you are". Damon Harrison Sr. tweeted, "...Did that wake some of y'all up now?".

Kaepernick claimed to be blackballed by all 32 teams following being released for his on the field protest in support of the Black Lives Matter movement. Ads following his release have focused on a simple tagline "Believe in something. Even if it means sacrificing everything." In 2019, Hip Hop artist and businessman Jay-Z partnered with the NFL in promoting their social justice efforts. As a supporter Kaepernick's efforts to protest police brutality against the black people of America, Jay-Z became an intermediary between the NFL and the black community. Alongside NFL commissioner Roger Goodell, Jay-Z has made efforts to make things right in the relationship between Kaepernick and the NFL by arranging a workout for the former 49ers QB to showcase his talents to all teams in need of a Quarterback. Later in 2019, Kaepernick and the NFL agreed to hold a workout session to showcase Kaepknick's talents as a competitive Quarterback and potential Super Bowl contender. Many disagreements about the transparency of the workout and accusations that Kaeperknick simply wants to manipulate the situation for profit circulate around social media. Kaeperknick remains without a team despite many teams' need for a Quarterback.

Issues in sports commentating

Racial remarks have been made about athletes of color throughout history. Radio host Don Imus described the Rutgers University women's basketball team as "nappy-headed hos" on his radio program "Imus in the Morning" in 2007. Later on he proclaimed that the match-up between Rutgers and their opponents looked like a showdown of the "jigaboos versus the wannabes."

In 1988 sports commentator Jimmy "the Greek" Snyder proclaimed his theory on why Black Americans are more athletic than White Americans: "The black is a better athlete to begin with because he's been bred to be that way, because of his high thighs and big thighs that goes up into his back, and they can jump higher and run faster because of their bigger thighs and he's bred to be the better athlete because this goes back all the way to the Civil War when during the slave trade … the slave owner would breed his big black to his big woman so that he could have a big black kid …"

Snyder would later express regret for his comments shortly after they aired, telling The Washington Post that "I thought I was being instructive, when in fact, I was destructive".

Snyder was later fired by CBS.

Sherman Maxwell was the first African American sports broadcaster. He began his career in 1929 on WNJ radio. He was known as "the voice of Newark".

Portrayals in film

While there are discrepancies in "based on a true story" sports movies, the movies are still representing the harsh realities of race and sports well. The US-set films Hoosiers and Rudy have been described as memorializing the "golden age of sports" as a time of white prevalence and dominance, while Glory Road showed a white coach helping to dissolve the color barrier in college basketball.

Another movie that received critical acclaim was 42. This movie was the Jackie Robinson story, a young man who was the first black player in the MLB. This movie focused on the journey Robinson took throughout his first year in the major leagues, going through the ups and downs. There were some moments that critics felt like producers could have given more depth to different characters, but overall the film represented that time in America and sports well.

Invictus deals with the subject of the 1995 Rugby World Cup in post-apartheid South Africa.

Some movies about black athletes don't focus completely on the aspect of race. The 2001 movie Ali, a film about great boxer Muhammed Ali, was another story about the journey through his life, but only briefly focused on racial aspects. There were mentions of some of his career being after the assassinations of Malcolm X and Martin Luther King Jr, but most of the film reflected on Ali and his personal journey that had little to do with the color of his skin. In 2022 a film was announced about the 1956 Sugar Bowl, which included the first black player to play in a college bowl game in the deep south.

Australia

Inequality in sport for the Aboriginal Australians exists due to material barriers. A 2007 report by the Australian Human Rights Commission suggested that fear of "racial vilification" was partly responsible for the under-representation of Aboriginal and other ethnic groups in Australian sports.

In the recent years, the influence of Polynesian players on the NRL National Rugby League has grown, with figures from the 2011 season showing that 35% of NRL players and over 45% of NRL Under-20s players are of Polynesian background. (By way of comparison, less than 3% of the Australian population identified themselves as Polynesian in the 2021 Australian census). This increase in Polynesian players has been blamed for the decline of Indigenous players, dropping from 21% in the 1990s to 11% for the 2009 season.

At the elite level of the game, Aboriginal Australians represented 35% of the roster for the Kangaroos, 21% of players at the 2012 State of Origin series, 12% of NRL players and a further 8% of the NRL Under-20s players. By way of comparison, 2.3% of the Australian population identified themselves as Indigenous in the 2006 Australian census.

South Africa

In South Africa, black representation on the cricket and rugby national sports teams is ensured via the introduction of quotas.

United States

Discussions of race and sports in the United States, where the two subjects have always been intertwined in American history, have focused to a great extent on African Americans. Depending on the type of sport and performance level, African Americans are reported to be over- or under-represented. African Americans compose the highest percentage of the minority groups active at the professional level, but are among those who show the lowest participation overall. And though the list of African Americans in professional sports remains high, it only represents a small fraction of aspiring black athletes. The Journal of African American History’s (JAAH) Special Issue on African American participation in sports in the 19th and 20th centuries demonstrates that African Americans have often used sports to challenge the social subjugation of their communities and stigma of the society. 

In 2013, while 2.8% of full-time degree-pursuing undergraduates were black men, the group comprised 57% of college football teams, and 64% of men's basketball players, according to Shaun R. Harper. While blacks predominate in football and basketball, whites predominate in all other regulated sports.

A 2001 study indicated that black high school students play harder than white students, because the former were more likely to perceive sports as a venue to success. The study denies that racial characteristics, per se, are a factor in success in sports. Despite such evidence, pseudo-scientific conceptions of race continue to play a role in the way many in the United States understand African-American contributions to sports.


For all races and sports, from 3.3% (basketball) to 11.3% (ice hockey) are successful in making the transition from high school varsity to an NCAA team. From .8% (men's ice hockey) to 9.4% (baseball) successfully transition from NCAA to professional teams. Therefore, the overall success rate of high school athletes progressing to professional athletes was from .03% (men and women's basketball) to .5% (baseball). The annual number of NCAA athletes drafted into professional sports annually varied from seven (men's ice hockey) to 678 (baseball).

Unlike black athletes, blacks as a group have not perceived sports as an important venue to prosperity. There are higher participation rates by blacks as well as higher numbers of people in non-athletic endeavor, such as policy, teaching, physicians, lawyers, engineers, and architects.

Athletics have been increasingly subsidized by tuition. Only one in eight of the 202 Division I colleges actually netted more money than they spent on athletics between the years 2005 and 2010. At the few money making schools, football and sometimes basketball sales support the school's other athletic programs. The amount spent on an athlete in one of the six highest-profile football conferences, on average, is six times more than the amount spent to educate the non-athlete. Spending per student varied from $10,012 to $19,225; cost per athlete varied from $41,796 to $163,930.
