Glucose plays a vital role in energy production during exercise, serving as the primary fuel source for most physical activities. When carbohydrates are consumed, they are broken down into glucose, which is then utilized by muscles for ATP (adenosine triphosphate) production during high-intensity workouts. Maintaining optimal glucose levels through balanced nutrition is crucial to enhance endurance and performance, especially in prolonged or vigorous exercise. Inadequate glucose can lead to fatigue, decreased performance, and impaired recovery.
