The primary function of carbohydrates in relation to exercise is to provide a quick and readily available source of energy. During physical activities, especially high-intensity workouts, the body relies on carbohydrates for fuel. They are converted into glucose and stored as glycogen in muscles and the liver, which is then used during exercise. Consuming adequate carbohydrates enhances performance and aids in recovery post-exercise by replenishing glycogen stores. A diet rich in complex carbohydrates helps sustain energy levels for prolonged activities and ensures optimal athletic performance.
