What role do carbohydrates play during exercise?

Carbohydrates are recognized as the primary fuel source during exercise, particularly during moderate to high-intensity activities. When the body engages in strenuous physical activity, it relies on carbohydrates in the form of glucose for energy. This glucose is derived from the glycogen stored in muscles and the liver.

During exercise, the body prioritizes carbohydrates for quick energy because they can be broken down into glucose more rapidly than fats or proteins, making them crucial for sustaining performance. The ability to readily use carbohydrates helps maintain stamina and prevent fatigue.

While other nutrients like proteins are essential for muscle repair and fats serve as an energy source during low-intensity activities, they do not provide the immediate energy demands necessary for most exercise regimens. Hydration, though vital for overall performance, does not directly supply energy in the same way carbohydrates do. Carbohydrates are, therefore, indispensable for athletes and individuals engaging in physical activities that require endurance and strength.
