Gymnastics isn't a purely explosive sport, ok. But I don't say 'HEY ONLY WHITES AND ASIANS GET MEDALS. BLACK PEOPLE JUST AREN'T THAT COORDINATED.' There are alternate explanations (societal, cultural) and I can't tell which one is the RIGHT one just by guessing.
Also oly weightlifting IS an explosive sport with not much technique and all the greats are white, arabic, asian, etc, not black. I don't say 'WHITE PEOPLE ARE STRONGER' because there are too many alternate explanations that i can't rule out. get what i'm saying? maybe white/asian people ARE better gymnasts, maybe black people ARE better sprinters/football players, but I'm just saying there's not really a way to be SURE about it currently though you can make conjectures.
