The role of carbohydrates in muscle glycogen synthesis is significant, as they serve as the primary energy source for high-intensity exercise. After physical activity, muscle cells replenish glycogen stores by absorbing glucose. Consuming carbohydrates post-exercise facilitates this process, enhancing recovery and preparing muscles for future workouts. It is essential to consume adequate amounts of carbohydrates, especially for athletes or those engaged in regular strenuous exercise, to maintain optimal performance and muscle recovery while preventing fatigue.
