Why cant white mean find success in the 100m but can in the 400m?

Question

This is not a racist question, i am looking for an explanation for why a white man has never ran the 100m in 10 secs but have great success in the 400m(jeremy wariner). Is it genetics? Are black people just faster then white people or do they just have better acceleration? Do you think there will be any white men to run the 100m in 9.7 without any extra technology?

Answer 1

Honestly Jeremy Wariner is the first to be great in the 400m. He's been the best since Michael Johnson the current 400m WR holder. And Jeremy is being trained by Michael. So it's hard to say. Genetics and everything.

Answer 2

Genetics & environment are the 2 biggest factors.

All the dark skinned people are related and I think the american ones came from n area of africa where there are more sprinters. They essentially have more fast twitch fibres than a lot of european types. Research shows that you can may slow twitch think it is fast twitch. Perhaps it is a case of white americans thinking they can't be sprinters so do not try.

Environment is another factor. The africans can improve their lifestyle by being good runners. Kenyans live in a high altitude area so with them naturally running everywhere they are genetically adapted over many years to be good fast endurance beings.

And of course you will always get the exceptions.
