Glucose is a crucial source of energy during workouts, particularly for high-intensity exercises. It is the primary fuel used by muscles for contractions and is stored in the form of glycogen. When performing strenuous activities, glucose levels can deplete rapidly, leading to fatigue. Consuming carbohydrates before exercise can help to maintain energy levels and enhance performance. In addition, adequate glucose supply aids in muscle recovery post-workout, balancing blood sugar levels, and improving overall endurance.
