i know that whites and blacks are not the same, white people have rounder shorter muscles, where as blacks have longer skinny ones. football trainers and shit did a big thing bout 8 years ago on it when talking about the giants cb jason sehorn. he being white and playing a position that is made up of mostly black guys. nothing was said about strength but speed was in favor of the black guys. i would imagine that white guys would have the upper hand in the upper strength, where as black guys would be faster, and looking at runners in the world and all the strong man stuff i would say that is what it is. no clue if that helps, and just fyi, i am a half black, and white. so i am not trying to start any thing just putting that out there.
thank you for not killing me
