Carbohydrates play a vital role in athletic performance by serving as the body's primary energy source. During exercise, especially high-intensity activities, carbohydrates are metabolized into glucose, which fuels muscle contractions. Adequate carbohydrate intake supports glycogen stores, determining endurance and recovery. Consuming carbohydrates before and after workouts can enhance performance and facilitate quicker recovery from fatigue. Athletes should focus on complex carbohydrates like whole grains, fruits, and vegetables for sustained energy release while also incorporating simple carbohydrates for quick energy replenishment during prolonged activities.
