Glucose is essential for physical performance as it serves as a key energy source for muscle cells during exercise. Carbohydrates are broken down into glucose, which is then used to fuel high-intensity workouts. Maintaining adequate glucose levels is crucial for sustaining performance, as insufficient glucose can lead to fatigue and decreased endurance. The timing of carbohydrate intake, both before and after exercise, can also influence performance and recovery. Consuming the right amount of carbohydrates helps replenish glycogen stores, thereby enhancing overall physical capability during subsequent sessions.
