Chocolate milk is an excellent recovery choice. After a hard workout, your muscles want carbs to refuel and high quality protein to build and heal. Rather than buy an expensive engineered sports food, enjoy a tall glass of low fat chocolate milk (or any flavored milk, for that matter).
In a study with cyclists who:
--depleted their muscles during an exhaustive bike ride, and then
--refueled with equal amounts of carbs in chocolate milk or a commercial recovery drink,
--then the next day did a time trial,
the cyclists gained no performance benefits from the commercial drink.
The bottom line: Save your moneyand also nourish your body with a whole food that offers far more life-sustaining nutritional value than just carbs and protein. Likely tastes better, too!
