In sports nutrition, carbohydrates serve as the primary energy source for athletes. They provide the fuel needed for high-intensity and endurance activities, replenishing glycogen stores in muscles and the liver. Including carbohydrates in meals before and after workouts enhances performance and recovery. Complex carbohydrates, such as whole grains, fruits, and vegetables, are preferred for sustained energy release. Proper carbohydrate intake promotes optimal performance, reduces fatigue, and supports long-term training goals. Balancing carbohydrate consumption with other macronutrients enables athletes to maintain energy levels and overall fitness.
