- In athletics, performance may be inhibited by as little as a 2% decrease in body weight due to hydration loss. Water has traditionally been the primary mode of hydration, but recently, carbohydrate-electrolyte sports drinks (CESD) and carbohydrate protein drinks (CPD) have started to gain popularity due to their inclusion of nutrients that may aid in performance. This study’s aim was to determine the effects of different modes of hydration on anaerobic performance following aerobic fatigue among physically active individuals. It was hypothesized that ingesting a CESD rather than water or a CPD prior to all activity would lead to lower times and greater distances. Seventeen recreationally active collegiate students were recruited for this study. This was a cross-over study that used a within-participant design in which subjects drank one of three drink conditions (300 milliliters of water, 355 milliliters of CESD (Gatorade), or 355 milliliters of CPD (Accelerade)). Following consumption of the beverage, subjects waited 30 minutes to ensure absorption, ran for 30 minutes, and then completed three trials each of three anaerobic tests: a 10-yard sprint, an agility drill, and a broad jump. One-way ANOVA revealed no significant difference in anaerobic performance under any drink condition. These data indicate that for short duration aerobic exercise followed by anaerobic activity, different types of drinks have no effect on performance in physically active individuals. Future research could investigate trained athletes instead of recreationally active or utilize a longer period of aerobic fatigue that would more closely mimic typical competition game play.
