An abstract of 'Chocolate Milk as a Post-Exercise Recovery Aid' can be found here:
The full paper needs to be paid for.
The report is by exercise kinesiology professor Joel Stager and colleagues from Indiana University.
Nine male cyclists performed a strenuous lab workout then drank one of three drinks: chocko-milk,?Gatorade and a carbo/protein sports drink.
After a rest period, the cyclists did ramp tests again, this time to exhaustion.
Stager's report said that cyclists who drank choco-milk at the break were able to continue cycling about 50?percent longer than those who drank the carbo/protein drink and about as long as those who drank Gatorade.
The dairy industry moo-ed its approval of the the report. Gatorade said the report was flawed.
The CEO of the US sports drink maker cited in the report told the Los Angeles Times the study was "like a cigarette manufacturer concluding that smoking is good for you.
Sports nutritionists say the study is too small to be truly worthwhile and were perplexed by the results for Gatorade, which is not a recovery drink.
