Carbohydrates serve as a primary energy source during exercise, particularly for high-intensity activities. They are broken down into glucose, which is readily accessible for muscle fuel. Consuming carbohydrates before and during prolonged workouts can help sustain energy levels, improving performance and delaying fatigue. The storage form, glycogen, is crucial for endurance athletes, as it provides the necessary energy for extended exertion. Employing a well-rounded diet with adequate carbohydrates allows athletes to optimize their performance and recovery.
