What's the Best Exercise Drink?

The best drink to take when you exercise is the one you like best. A study from Gatorade Sports Sciences shows that the rate the rate that fluid leaves the stomach is not dependant on the concentration of sugar or salt, or the temperature. Glucose and fructose drinks are absorbed equally because fructose is converted immediately to glucose in the intestine or liver.

Previous studies showed that carbon dioxide bubbles in soft drinks do not affect absorption either. Cold drinks are warmed above 30 degrees centigrade in fewer than five minutes. The most important rule for taking fluids during athletic competition that lasts more than an hour is take as much fluid as possible and this study supports many other studies to show that the drink that you drink the most of is the one that you like the best.
