Chocolate Milk: The New Sports Drink? - UK-Muscle Body Building Community

Feb. 24, 2006 -- During a 2004 Summer Olympics awash in controversies over steroids and supplements, one sportswriter wryly noticed that top American swimmer Michael Phelps was playing it safe -- he preferred to drink Carnation Instant Breakfast between races.

Now it appears that the six-time gold medalist may have been onto something. A new study shows that plain old chocolate milk may be as good -- or better -- than sports drinks like Gatorade at helping athletes recover from strenuous exercise.

The study, published in the International Journal of Sport Nutrition and Exercise Metabolism, was small in scale; it was partially funded by the dairy industry. But dietitians say the study should help to counter the notion that high-tech, expensive supplements are better than whole foods when it comes to athletic performance. They also note that milk contains key nutrients, such as calcium and vitamin D, in quantities that sports drinks can't match.

"[Milk] is a sports drink 'plus,'" Keith Ayoob, EdD, a registered dietitian and associate professor of pediatrics at the Albert Einstein College of Medicine, tells WebMD. "It will supply you with things you need whether or not you're working out."

The study builds on findings that intense endurance exercise reduces the muscles' supply of stored glucose, or glycogen, a key source of fuel for exercise. To maximize glycogen replacement, the American College of Sports Medicine and the American Dietetic Association recommend taking in a serving of carbohydrates within 30 minutes after a long and vigorous workout.

Milk vs. Sports Drinks

Common sports drinks such as Gatorade supply those carbs, as well as fluids and electrolytes lost through sweat. However, more recent research suggests that adding protein to the mix may further hasten recovery. Hence the new wave of drinks such as Endurox R4 that include protein as well as higher doses of carbs.

In the study, nine male cyclists rode until their muscles were depleted of energy, then rested four hours and biked again until exhaustion. During the rest period, the cyclists drank low-fat chocolate milk, Gatorade, or Endurox R4. During a second round of exercise, the cyclists who drank the chocolate milk were able to bike about 50% longer than those who drank Endurox, and about as long as those who drank the Gatorade.

The findings suggest that chocolate milk has an optimal ratio of carbohydrates to protein to help refuel tired muscles, researcher Joel M. Stager, PhD, Indiana University kinesiology professor, tells WebMD.

But the most puzzling result of the study, experts say, was why Endurox -- which has the same carb-to-protein ratio as the chocolate milk -- fared so poorly. Researcher Jeanne D. Johnston, MA, tells WebMD it may have to do with the different composition of the sugars in the milk. Another theory is that the sugars in the milk may be better absorbed in the gut than those in the Endurox.

Edward F. Coyle, PhD, a researcher on exercise and hydration at the University of Texas, tells WebMD the trial would have been stronger if the researchers had also tested the effect of flavored water or another dummy (placebo) drink.

The study was partly funded by the Dairy and Nutrition Council, an industry group. Coyle says that the study's reliance on industry funding is not unusual in the world of sports research, as federal funding for such research is hard to come by.

A Cheaper Alternative?

While rapid nutrient replacement may not be important for casual exercisers, it can make a big difference in performance for competitive athletes who work out vigorously once or twice a day, says Roberta Anding, a sports dietitian and spokeswoman for the American Dietetic Association.

Anding has long recommended chocolate milk for young athletes who come to her practice at Texas Children's Hospital in Houston. For children and teenagers from lower-income families, it doesn't make sense to spend serious money on sports drinks when they can get milk as part of a subsidized lunch program, she tells WebMD. The only advantage of sports drinks, she notes, is that they never spoil.

Ayoob estimates that more than two-thirds of teenagers should be drinking more milk anyway because they don't get enough calcium in their diets. He also recommends milk for its vitamin D and potassium content. "For me, this is a no-brainer," he says.

Cool, thanks.

Milk is a fast carbohydrate. Diabetics can only drink 4 oz a meal.
I have a hard time with milk for rehydration after a serious work-out.. It is too thick and creamy and sticks in my throat and sits heavy on my stomach and makes me more thirsty.

But I can see how it could be considered a good alternative to sports drinks. It contains protein and has a fast GI, GL, II.

It just doesnt' satisfy my thirst and isn't for me after a hard work-out.

Interesting post.
I love chocolate milk fortified with chocolate whey and Instant Breakfast for breakfast.

Seems that the things our grandparents ate are coming back into vogue and have value.

I like that for some reason.
