Carbohydrate intake significantly influences exercise performance by providing the primary source of energy for working muscles. During high-intensity activities, carbohydrates are crucial for maintaining stamina and optimizing performance. Adequate carbohydrate consumption before, during, and after exercise helps replenish glycogen stores, supports recovery, and improves endurance. Individual needs may vary based on the type and duration of the exercise, highlighting the importance of tailored nutritional strategies to enhance athletic performance effectively.
