Question: 1 / 400

What role do carbohydrates play in exercise?

They provide a primary source of fuel for high-intensity exercise

Carbohydrates serve as the primary source of energy for the body during high-intensity exercise. When engaging in activities that demand quick bursts of energy, such as sprinting or heavy lifting, carbohydrates are broken down into glucose, which can be rapidly utilized by the muscles. This swift availability of energy is crucial for sustaining performance and preventing fatigue during intense physical activities.

In addition to this primary function, carbohydrates play a significant role in restocking energy stores post-exercise, which is vital for recovery. However, they do not primarily enhance muscle recovery; instead, protein is more directly associated with muscle repair and growth. While hydration is essential during workouts, carbohydrates do not directly contribute to hydration. Lastly, carbohydrates themselves do not build muscle mass; instead, they provide the energy necessary for strength training, which, in conjunction with adequate protein intake, contributes to muscle hypertrophy. Thus, the statement about carbohydrates being a key source of energy for high-intensity exercise is aligned with their physiological role in sports nutrition.
