Carbohydrates play essential roles in endurance sports by serving as the primary energy source during prolonged activities. They are stored as glycogen in muscles and the liver, providing quick access to energy when required. Adequate carbohydrate intake before, during, and after endurance events helps maintain performance, sustain energy levels, and expedite recovery. Different types of carbohydrates, including simple sugars for immediate energy and complex carbs for longer-lasting fuel, are important for optimal athletic performance. Therefore, proper carbohydrate management is crucial for endurance athletes aiming to achieve peak performance.
