Is I caused by the same factors as in a marathon (26 miles)? What about 100-200 meters? What are the best and most efficient methods of training athletes for their respective sports? What makes the elite or super athlete? Can he/she be identified physiologically? Can average people reach elite status by training? o Muscle Fiber Types o Fast twitch (FT) o Slow twitch (ST) Effects of environment on performance?
