English researchers pronounce chocolate milk the ultimate sports drink

You' ve probably never sat around discussing the virtues of chocolate milk as a sports drink.
You probably also never had a conversation that went something like this, "Say Bruce, what do you think is the best sports drink? Do you suppose it is that purple stuff that has lots of salt or perhaps that orange stuff that' s supposed to increase your performance, or---do you think it could be chocolate milk?"
But that' s exactly the conversation that researchers had in England at Northumbria University recently when they compared the effects of three beverages on performance in a cycling endurance test.
The three beverages were chocolate milk, a commercially available
sports drink, and a commercially available fluid replacement drink.
And by now you' ve guessed that chocolate milk came out on top.
"On three occasions, nine trained male cyclists completed a glycogen
depletion workout, drank one of the three test beverages during a
four-hour recovery period, and then cycled in an endurance capacity
When the cyclists were given chocolate milk, they were
able to cycle 51 percent longer in the endurance test before exhaustion
than they did when they were given the sports drink and 43 percent
longer than when they were given the fluid replacement drink.
researchers noted that participants cycled longer after drinking
chocolate milk than after sports drink, despite the beverages having
very similar calorie (or energy) contents. They said the difference
could be due to differences in carbohydrate type and (or) fat content
between the beverages."
