Summary

Athletes participating in multiple training sessions a day can be at increased risk of suboptimal hydration and heat illness during their second training session, especially when the environment is hot and humid. With the exception of the absolute volume of water delivered by a rehydration beverage, characteristics of the beverage consumed play a role in the recovery and completeness of rehydration. The amount of sodium in the beverage has been shown to be a primary factor in rehydration. Recently, an effect of the carbohydrate concentration of the beverage was been reported, with its effects mediated by the renal system in response to elevated serum insulin. The purpose of this study is to compare sodium and carbohydrate effects on rehydration and recovery.
