Describe the appropriate procedure for carbohydrate loading


Carbohydrate loading—a practice that endurance athletes use to trick their muscles into storing extra glycogen—may not be beneficial for people who exercise less than 90 minutes per workout at a low intensity, although competitive athletes who exercise at a high intensity for more than 90 minutes at a time may benefit from carbohydrate loading. Muscles typically have enough glycogen to fuel 1.5 to 2-hour bouts of activity.

An athlete who follows the glycogen-loading technique in preparation for an upcoming event will first exercise intensely without restricting carbohydrates and then gradually cut back on exercise the week before the competition, rest completely the day before, and eat a very high-carbohydrate diet. Endurance athletes who follow this plan can keep going longer than their competitors without ill effects. In a hot climate, extra glycogen offers an additional advantage. As glycogen breaks down, it releases water, which helps meet the athlete's fluid needs.
