Document Summary

As intensity of exercise increases, the muscles will reduce the fat and use more glycogen. If the exercise is long and intense enough that glycogen depletion might occur, then cho in the diet will be very important. Glycogen depletion = critical low levels of glycogen in the muscles that are being exercised. When muscles run out, individual has hit the wall" > the muscles only have fat left to burn. Fat can only be burned in oxygen. (fat can only be used by the muscles when oxygen is available) = an aerobic fuel. Exercise in hot conditions, muscles will use more glycogen. Exercise in cool conditions, muscles will use more fat: what is the training status of the athlete? (how t the person is) Those who exercise regularly, muscles will burn fat more easily. Your muscles adapt to burn more fat, so you spare the glycogen.
