It is well known that ingesting GES drinks during prolonged exercise may help spare muscle glycogen and prevent dehydration. However, the use of GES drinks during endurance exercise has also been shown to blunt increases in FFAs and attenuate increases in the ratio of free tryptophan to BCAAs, enhancing endurance capacity. These findings suggest that the use of GES drinks during endurance exercise may be an effective nutritional strategy to delay the onset of fatigue via both peripheral and central mechanisms. Additionally, there is some recent evidence that suggests ingesting GES drinks during exercise may lessen the effects that intense exercise has on the immune system. Theoretically, use of GES drinks during training may help an athlete maintain glycogen and hydration levels, delay peripheral and central fatigue, and/or stay healthier. However, although there is a significant body of evidence to support use of GES drinks during prolonged intermittent and endurance exercise, there is little evidence that use of GES drinks during training will help athletes tolerate training to a greater degree and/or lessen the severity of symptoms of overtraining. Nevertheless, we believe that if an athlete is training more than 1 hour per day, frequent use of GES drinks or gels should be encouraged, particularly when training in hot and humid environments.
