Added carbs from drinks would be useful only after several hours of exertion, when the body starts to draw upon its stored glucose, known as glycogen, for energy. But the subjects in the study were showing improved times and greater power in sessions lasting 60 minutes or less. Were they experiencing a sugar rush from the beverages they were gulping...

The experimenters say BZL101 works by preventing cancer cells from undergoing glycolysis, a process of glycogen breakdown that accounts for as much as 85% of cancer cells' energy supply...
...first day is survival for me because everyone is so amped and they go out fast," says Rusch of the five-man, one-woman team she leads. "I'm just hanging on so I don't fall back." After just two hours, she has used up most of her glycogen--a form of energy derived from sugar and stored in muscles and certain organs--and her body starts running on fat and whatever calories she gets from the food she eats while racing.
