Why the average black male is faster than males of other races, i think its because of a few reasons... One because of soemthing already proven that blacks have denser muscle composition with less fat in between the muscles, two because of the fast twitch muscles, and 3 my own opinion, is because of the body porportions...A black male is more biased lower body while the majority of the other races are more upper body biased, for instance, stand an equal weight and height black and white man next to each other and the white mans hips will sit lower on his body with a longer mid section and wider torso. Another example is a white man and black man of equal size sitting down next to each other in a chair, the white man will be noticably taller in the seat. .Blacks tend to have longer legs ( more stride in there run) while having shorter upper body. Now this could effect a blacks overall upper body potiential as far as heavy weight lifting, but this is more than likely why the black man is more dominante and more biased towards sports or events that require anything were running and jumping is required. This is directly related to the black mans natural ability to jump higher as well as less upper body weight giving a more balanced porportion to push upwards since jumping mainly focases on the legs. Also longer legs means more muscle mass devoted thru the legs.I see it as running really fast with shorter legs takes more energy and less graceful motion as the legs have to sped up to match the same distance covered due to shorter stride. In example to my theory, running with your pants pulled half way down you cant stretch your legs as far and get up to the same speeds. Same theory in comparison to shorter legs vs longer legs...Thats my opinion off of personal analysis which i find to be at least somewhat correct...
