This study tests whether Gatorade could ensure a better rehydratation than water. The rapid and efficient replacement of the fluid sweat lost is an important means for maintaining effort capacity. An optimal rehydration beverage must fulfill more requirements: to encourage consumption, to ensure a quick intestinal absorption and a slow urine elimination rate. The study assessed whether replacing sweat losses with sodium-free fluid can lower the plasma sodium concentration and can lead to losing more fluid during exercise, with negative effects on cardiovascular activity and physiological stress.

Measurements of sweat loss, diuresis, natremy, fluid ingestion and heart rate were some of the parameters that demonstrated Gatorade’s efficiency as a rehydratation fluid. Based on the results of the study, we can appreciate the benefits of the Gatorade fluid replacement during aerobic gymnastic training.

Key words: 

rehydratation, GATORADE
