Carbohydrates play a crucial role in providing energy, especially during exercise. When the body engages in physical activity, it relies on glucose, which is derived from carbohydrates, as a primary fuel source. This is because carbohydrates are easily broken down into glucose, making them readily available for immediate energy use.

During high-intensity exercise, the demand for energy increases and the body preferentially utilizes carbohydrates over fats due to their faster conversion to energy. This quick energy provision is vital for maintaining performance and endurance. Furthermore, the availability of carbohydrates can influence the overall workout efficiency, delaying fatigue and enhancing recovery post-exercise as glycogen stores are replenished.

Hydration is essential for exercise, but it is primarily maintained through fluids rather than carbohydrates. While digestion is important for nutrient absorption, it doesn't directly supply energy during exercise. Tissue repair occurs after physical activity, supported by proteins and other nutrients rather than carbohydrates. Therefore, the primary function of carbohydrates during exercise is to serve as a quick energy source.
