White Men Can’t Jump, Black Men Can’t Shot-Put.

The present work distinguishes four basic racial groups — Europeans, Northeast Asians, West Africans, and East Africans — and describes the peculiarities of each group as they relate to athletic performance. Most other populations can be treated as clines between these main groups.

Relevant physical traits include body type, height, lung capacity, musculature, length of limbs, reaction time, and testosterone levels.

Three fundamental body types, or somatotypes, are distinguished: (1) endomorph, or fat and stocky; (2) ectomorph, or slim; and (3) mesomorph, or muscular. Actual persons are commonly mixtures of these three types in variable proportion.

Broadly speaking, West Africans are mesomorphic, with leaner bodies, more muscle containing a higher proportion of fast-twitch fiber, and narrow hips. Their relatively small lung capacity keeps them from success at endurance-based competition, but they dominate sports requiring short bursts of power or speed. High plasma testosterone levels make them good at aggressive contact sports.

East Africans, or more specifically those whose ancestors lived in the highlands of East Africa for an evolutionarily significant period of time, are similar in many respects to West Africans, but are more ectomorphic, with greater lung capacity, more efficient processing of oxygen, and more slow-twitch muscle tissue. These traits make them well-adapted to long-distance running. Since the 1960s, a single East African group, the Kalenjin of Kenya, have come to dominate international long-distance running competitions despite a tendency to invest modestly in training. Their homeland lies 8,000 feet above sea level.

Europeans fall between West and East Africans with regard to lung capacity and the distribution of fast-twitch and slow-twitch muscle fiber. They fall between Africans and Northeast Asians in many other traits. They have superior upper-body strength and a tendency to endomorphy. Field events such as shot-putting and hammer-throwing are dominated by Europeans, especially Northern Europeans.

Northeast Asians are even more endomorphic than Europeans, with a thicker layer of subcutaneous fat and less muscle tissue. Their strengths include quick reflexes, flexibility, and visuospatial skills. The sport in which they are best known for excelling is table tennis, but badminton is even better suited to their particular strengths.

Dutton and Lynn examine women’s sports as well. Since men are better at all kinds of athletic contests than women, the women who achieve at the highest levels tend to be less feminine than average. Also significant are racial differences in sexual dimorphism: African women and others from tropical regions are less distinct from their men than are women closer to the Arctic.

Dutton and Lynn examine data concerning the best male and female performers in over fifty sports and compare them with predictions based on the physical traits of each of these racial groups. The results are extremely impressive, although they provide no proof that the predictions were made independently of the data by which they are tested. This is an issue mainly in regard to ad hoc explanations of exceptional cases; in the main lines, the predictions that would follow from racial differences are clear enough.
