Drink of Champions: Chocolate Milk?

Several years ago, a high-school swimmer in Bloomington, Ind., handed
his coach a sports drink to see what he thought of the beverage. The
ingredients looked familiar to Joel Stager, an exercise physiologist at
Indiana University Bloomington and director of the Counsilman Center for
the Science of Swimming. But it took a trip to the grocery store to
find the supplement's nonsynthetic cousin, chocolate milk.
Soon Stager was handing his swimmers, many of whom struggled with
their twice-a-day practices, a glass of chocolate milk after their early
morning workouts. The effect was dramatic. Many of their problems
disappeared "almost immediately," he says.
The benefits did not escape the swimmers' parents, who didn't need
academic research to convince them that low-tech chocolate milk was a
super fuel for exhausted muscles, and kids.
"When I'd get to practice in the morning, there would be a couple of
gallons of chocolate milk waiting for me," Stager recalls. "It was
great. It sent a good message to the athletes that eating well is
important."
Stager took chocolate milk into the controlled setting of his IU
laboratory and tested its effect on cyclists. It performed as well as
Gatorade and almost twice as well as another sports recovery drink,
Endurox.
The results--which might seem too good to be true to the legions who
consider chocolate milk an indulgence--were reported in newspapers
across the country, magazines such as
Sports Illustrated, on NPR's Morning Edition, and on health Web sites such as WebMD. In spring 2006, the findings were published in the
International Journal of Sport Nutrition and Exercise Metabolism,
resulting in a promotional campaign by the Milk Processor Education
Program (Got Milk?). After that campaign overstated chocolate milk's
performance compared to Gatorade, somewhat defiant Gatorade spokesmen
entered the media fray, generating even more attention.
Stager is surprised by the amount of interest from researchers and
practitioners since he first presented his research two years ago at an
American College of Sports Medicine conference.
"This isn't Nobel Prize research. The basic premise was already in
the literature in terms of what's appropriate post-exercise nutrition,"
he says. "But nobody ever thought, 'Gee, here's something that could
work that everyone's familiar with. It's easily accessible, tastes good,
and sends the right message.'"
As a result of news coverage for his research, Stager says, more
people may now be aware of the importance of nutrition immediately after
exercise. His research points to a short but critical window for
refueling muscles, within 45 minutes to one hour of exercise. Beyond
this window, the refueling effect of the chocolate milk or other
recovery products is not as effective.
Stager, a coach, competitive swimmer, and professor in the IU
Bloomington Department of Kinesiology, says the lure of sports drinks
and supplements can lead athletes down a dangerous path as they look for
any performance advantage.
"It doesn't take much for athletes to look for the silver bullet, the
edge," he says. "Many think they can get it through a specifically
geared product on the market. From the scientific side, most of these
products don't have any beneficial effects."
Good nutrition, on the other hand, can make a big difference on
performance. Some swimmers are talented from the beginning, while others
have to work hard to be good. Coaches, Stager says, can change an
athlete's performance "rather quickly" simply by teaching them how to
eat well. Another Counsilman Center philosophy encourages athletes to be
athletes 24/7, not just during practices. Eating right, Stager says, is
part of being an athlete.
The Los Angeles Times began its piece about Stager's
research with this: "One little milk study and everyone's having a cow."
What's next for this noisy little milk study? More research. Stager
plans to take a closer look at what makes chocolate milk so effective,
examining all its different components, from the proteins to the
chocolate. He wants to make comparisons with more sports products,
particularly those that replace carbohydrates, and use more test
subjects.
"It should help us come up with the answer to the question, 'What is the best way to refuel?'" he says.
