Carbohydrates play a vital role in improving performance during endurance activities. They serve as the body’s primary energy source, especially during prolonged exercise. Consuming adequate carbohydrates before and during activities helps maintain optimal blood glucose levels, providing sustained energy. This can delay fatigue and enhance athletic performance. Additionally, carbohydrates are essential for replenishing glycogen stores post-exercise, aiding recovery. Therefore, athletes should focus on incorporating complex carbohydrates such as whole grains, fruits, and vegetables into their diets for optimal endurance performance.
