Do African-Americans have an advantage in sports? Like in the Olympics?

Question

I'm watching the Olympics, and I barely ever see any white people in things like 100m dash, long jump, high jump, etc. Why is that?

Answer 1

 African americans have a greater number of Fast-twitch muscle fibres. This is why they are seen to dominate the sprinting world.

When it comes to long distance, the environment has a lot to do with there success. Higher altitudes and harsher conditions gives them a higher VO2 max so they are able to run longer distances at higher paces before they begin to fatigue.
