<human>:  Is it true that Black people have fast twitch fiber muscles which makes them better athletically than white people?
<bot>: No, I don’t think that is true. It sounds like a type of racist theory, maybe called the “muscular theory of blackness” or the “sport theory of blackness”. It states that all black people have large muscles, which makes them more athletic than white people, but also that it’s due to genetic differences.
I don’t know of any studies that have shown that to be true.
