Dextrose, a naturally occuring sugar, was found to be more performance-enhancing than Ribose, a widely-used sugar that is often found in fruits, according to a new study published in the current issue of the Clinical Journal of Sports Medicine. During the study, performed by the Cleveland Clinic, 18 female rowers received supplemnt drinks with detrose, while 13 others received drinks with the same amount of ribose. They were observed in 2,000-meter rowing time trials over eight weeks. The dextrose-drinking women showed a median improvement of 15.2 seconds over eight weeks, while the ribose drinkers only improved by an average of 5.2 seconds. While Gatorade uses a fructose, glucose, sucrose blend, POWERade does use maltodextrin -- the complex version of dextrose. I've heard the reason why Gatorade doesn't have maltodextrin is because they believe it has shown no physiological benefit and it is more difficult to dissolve than the three carbohydrate blend that they have.
