It has been widely established that the ingestion of carbohydrate (CHO) pre-, during and post-exercise can improve exercise performance in intense events that lasting longer than 60 to 90 minutes.CHO provides most of the energy for high-intensity endurance exercise (85% to 100% VO2max) [1], maintains blood glucose, and possibly spares endogenous glycogen stores [2]. Consequently, CHO supplementation could be appropriate for athletes competing in endurance events. Fluid intake is a one frequent way to deliver CHO before, during and after exercise. However, the disadvantages of CHO-beverage are the monosaccharide and disaccharide composition which making the beverage very sweet [1] and the rate of gastric emptying and intestinal absorption are too slow compare to other form of CHO [3].
