The usual reason given for Black athletic success is that Blacks have little chance to get
ahead elsewhere. But Entines new book (Taboo) shows that in sports, Blacks have a genetic edge.
The physical facts Entine reviews are quite well known. Compared to Whites, Blacks have
narrower hips which gives them a more efficient stride. They have a shorter sitting height which provides
a higher center of gravity and a better balance. They have wider shoulders, less body fat, and more
muscle. Their muscles include more fast twitch muscles which produce power. Blacks have from 3 to
19% more of the sex hormone testosterone than Whites or East Asians. The testosterone translates
into more explosive energy.
