I think you will find too much variation in limb proportions, hip proportions, calf insertion points, and fast twitch/slow twitch muscle rations among just the black population for any of these absurd generalizations to hold up. For example, Dial_tone or GJohnson probably have little in common, physically, with either a 7' NBA player or a Kenyan long distance runner.
