Carbohydrate loading is a strategy used by endurance athletes to maximize muscle glycogen stores before an event. This involves increasing carbohydrate intake several days before competition while tapering training intensity. Proper carbohydrate loading can enhance endurance performance, delaying fatigue and improving overall energy levels during long-duration activities. However, it’s important for athletes to practice this strategy in training to determine their optimal intake and avoid gastrointestinal discomfort on race day.
