Whey Vs. Chocolate Milk

Whey Vs. Chocolate Milk You've probably heard that chocolate milk has a suitable amino acid profile for kick-starting post-workout protein synthesis while the fast-carbs from chocolate help replenish the glycogen your body uses for short intense bursts of energy. A study published in the Journal of Undergraduate Kinesiology Research compared the attributes of chocolate milk to whey protein using 15 college students.

For 4 weeks, these volunteers worked out with weights 3 times a week. Each session lasted 30 to 45 minutes and encompassed 8 to 10 upper and lower body exercises. They did 3 sets of each exercise for 12 to 15 reps. Within 30 minutes of completing each training session, subjects received a 24 gram whey protein shake or a glass of chocolate milk containing 16 grams of protein.

Students who drank whey protein were able to perform 29 push ups on average compared to their pre-training limit of 20, and they gained over an inch of shoulder girth. That didn't happen for the chocolate milk drinkers, who managed only a statistical tie for wall-sit time with the whey drinkers.

True Strength Moment: It might have been the increased protein in the whey that helped develop muscle size and strength measurably better than chocolate milk, or it could be the highly refined nature of whey protein. Whatever it was, the whey shake drinkers probably also consumed fewer calories and a lot less fat and sugar in their recovery drinks.
