Carbohydrates play a crucial role during prolonged exercise by serving as a primary energy source. They are stored in the muscles and liver as glycogen, which the body utilizes during sustained physical activity. Consuming an adequate amount of carbohydrates before and during exercise can help maintain energy levels, improve performance, and delay fatigue. They also assist in faster recovery post-exercise by replenishing glycogen stores. Therefore, strategically integrating carbohydrates into the diet is essential for endurance athletes and physically active individuals to optimize performance and recovery.
