Carbohydrates play a crucial role in athletic endurance by providing the primary source of fuel for high-intensity activities. They are easily converted to glucose, which is essential for energy production during prolonged exercise. Maintaining adequate carbohydrate intake helps to replenish glycogen stores in muscles and the liver, enhancing performance and delaying fatigue during endurance activities. Proper carbohydrate consumption before, during, and after exercise supports optimal strength and endurance levels. A balanced diet including carbohydrates ensures athletes can sustain energy levels for both training sessions and competitive events.
