Not really. Kenyans can keep up their initial burst of speed longer because of increased lung capacity though. They live at higher altitudes than most people so their lungs adapt. A lot of athletes spend time in pressure tanks now to get the same effect. Interestingly enough, higher altitude also means thinner air, which is the reason why so many jumping records were broken at the 1968 Mexico Olympics.rednose1 said:Some people have just very odd beliefs that they hold true, no matter what. I knew a guy that would argue against anyone that black people could run faster because they had an extra leg muscle.
But I digress.
