The Facts:
Only consuming water is not an optimal nutritional strategy in most cases, except when engaging in low intensity aerobic training (aerobic lipolytic training). In most cases, even during high-intensity training when the body primarily relies on stored glycogen for fuel, exercise-induced adaptations and performance can be enhanced through following very specific nutritional strategies taking into consideration the type and intensity of the training. Furthermore, athletes often engage in multiple training sessions during a day and recovery after training sessions is of paramount importance. Appropriate nutrition during training can enhance recovery after training and can for e.g. assist to spare glycogen that may be required during subsequent training bouts.
