<BR><BR>Actually I think it's genetics that provide a lot of "red muscle" slow-twitch muscle tissue which provide for longer endurance over fast-twitch (white tissue). But altitude has a lot to do with it too.
No, there is no genetical differences that makes anyone have any greater amount of either fast or slow twich muscle tissue, it is in training and diet, you could take one of them, feed them a bodybuilders bulk diet and have them train with heavy weights, short workouts with high intensity and they would have as much fast twitch as anyone else doing it.
Remember that the best bodybuilder of all times, Lee Haney, was black.
Altitude training is like blood doping, more red blood cells to bring the oxygen to the muscles will result in better endurance, there is no question if it works, it does.
