The present study will assess the effects of two different hydration solutions compared to water on hydration measures. It will follow the same approach as used by Maughan and colleagues (2016) to measure the fluid balance (the difference between the amount of water consumed and passed as urine) and beverage hydration index (the relative amount of urine passed after consumption of a drink compared to water) including time in positive fluid balance. Additionally, hydration status will be assessed with mood and digestive health questionnaires and blood pressure urine electrolyte concentrations, specific gravity, and osmolality determinations. The two oral rehydration solutions (Berry Propel Fitness Water and Essentia Hydroboost Raspberry Pomegranate) will be compared to the control (Smart Water). The purpose is to assess whether the changes in beverage composition improve the BHI above water alone for both treatments, with an hypothesized greater improvement in BHI observed with the Essentia Hydroboost Raspberry Pomegranate, due to the addition of carbohydrate.
