GLUCOSE ONLY VS GLU-FRUCTOSE SPORTS BEVERAGE: WHICH IS BETTER?

Fructose has been getting a lot of bad press recently, with excessive amounts linked to rising obesity rates and cardiovascular disease in the general population.  Current opinion by health experts suggests that athletes may be protected from the adverse effects of fructose because it is used for energy during exercise by working muscles. Avoiding fructose by using a glucose-only sports drink may be one way to eliminate the negative effects of fructose.  When this idea was tested with nine well-trained cyclists performing a 100-km time trial using a glucose-fructose drink, and then a glucose-only drink, the results were clear.   All 9 cyclists completed the 100-km time trial significantly faster using the glucose-fructose drink.
