>>378024 blacks have higher muscle density _in_general_ (depends on the genes they inherited) which makes swimming harder. It's a phenotype, meaning you usually see these 2 genetic traits together: black skin, dense muscle. But not always, like hispanics or Indians or SE asians with black skin, their muscle density genes may differ.
where you're right: denser muscle = quicker, yes.
with boxing: if you win the fight, your skin color doesn't matter. you just have fuck the other guy up. that's what so great about it.
