After an exhaustive aerobic session, why is a 400-500 calorie carbohydrate meal recommended?

A 400-500 calorie carbohydrate meal after an exhaustive aerobic session is primarily recommended to replenish muscle glycogen. During prolonged aerobic exercise, the body utilizes glycogen, which is stored in the muscles and liver, as a key energy source. After such intense and extended physical activity, glycogen stores can become significantly depleted, which can hinder recovery and performance in subsequent workouts or activities.

Carbohydrates consumed after exercise help to restore these glycogen levels effectively. It is generally recommended to consume carbohydrates within a certain window post-exercise, often referred to as the "glycogen recovery window," to optimize the replenishment process. Eating a meal rich in carbohydrates ensures that the muscles receive the necessary nutrients to recover fully.

The focus of the other options does not align with the primary role of carbohydrates post-exercise recovery. While hydration is important, it is not the main goal of consuming a carbohydrate-rich meal. The statement about the liver and bloodstream being depleted by a specific calorie count is not accurate in the context of post-exercise recovery. Promoting fat loss is not the immediate priority after an exercise session where the body's primary need is to recover and restore energy levels. Thus, the best choice revolves around the replenishment of muscle glycogen, which is
