Re: Why black people are so talented in 100m run?
I remember doing this back in sport science, like 9 years ago. The reason is because blacks have a higher red blood cell count then whites, and if I remember rightly, it gives a better oxygen rate. Also I think there's something to do with a greater muscle percentage, and that they have longer legs, and shorter upper bodies then whites, which sees blacks excel in sprinting and the likes, but not so much in swimming. I also think that whites have a smaller achilles tendon, which is a major cause for this
