dc.description.abstract Sweat production during exercise results in a loss of electrolytes, particularly chloride, sodium and potassium ions as well as a loss of water. Sports drinks attempt to give athletes the proper ions needed to replenish the body, as well as increase the osmolality to improve fluid balance. Research in this field currently focuses on the effects of consumption of different rehydration solutions used both preand post-exercise. However, the analysis and comparison of concentrations of ions in different sports rehydration drinks has not been performed by third parties. This experiment focused on comparing the concentrations of chloride, sodium and potassium ions of Gatorade, Powerade, HyVee, All Sport, Propel, Muscle Milk and milk; when possible, we compared fluid versus powdered forms also. Samples from each type of sports drink were diluted and analyzed using EasyLyte Plus(TM), an electrolyte analyzer, examining concentrations of chloride, sodium and potassium ions. Significant differences were found between levels of sodium and potassium of (1) Gatorade Endurance and Gatorade, (2) Gatorade and Propel,(3) milk and all sports drinks, (4) Muscle Milk and all sports drinks. Differences in chloride levels were found in all of the above, except between Gatorade Endurance and Gatorade. No differences in electrolyte concentrations were found between liquid and powder versions of sports drinks. Concentrations of electrolytes differed in some rehydration drinks and could impact ion concentration and resultant fluid balance in athletes and dehydrated individuals. en_US
