Exercising in hot and humid environmental conditions produces high sweat rates and may lead to significant dehydration and decline in athletic performance. Hyperoxygenated beverages have been on the market for several years claiming hydration and health benefits and even enhanced athletic performance. The addition of vitamins and minerals increases osmolality, which may result in physiological responses that could enhance hydration status. To date, no research has provided evidence to support the claims, nor demonstrated any negative side effects, from drinking a hyperoxygenated beverage enhanced with vitamins and trace minerals. Purpose: When compared with water, our objective was to determine if a commercially available hyperoxygenated beverage (O2water), would limit dehydration when consumed during a sub-maximal running bout in hot and humid conditions. Methods: Experienced male runners (N = 12, Mean age = 24.2 years, VO2 = 61.9 VO2 ml/kg/min, height = 1.8 m, body mass = 75.1 kg, and percent body fat = 12.4%) completed two 45-minute runs at 70% of their pre-determined VO2max in a temperature and humidity controlled environmental chamber. Conditions were set to 30° C and 50% humidity. Subjects were randomly provided either O2water or water during their first run, and were permitted to consume ad libitum. For the second run, subjects were prescribed the same volume they consumed in the first run of the alternate beverage. Hydration status was determined via plasma osmolality pre-run and 30, 60, and 90 minutes post-run. Pre- and post-run nude body weight was used to measure sweat rate and fluid retention. Results: Average sweat rate and fluid consumption for subjects was 1,377 mL and 508 mL, respectively. Post urination body weight indicated greater fluid retention (52g), when consuming Oxywater water versus plain tap water. Pre-run osmolality averaged 288.3 mOsm/kg. When subjects consumed water, 90 minute post-run plasma osmolality increased 2.97 mOsm/kg. Conversely, when subjects consumed O2water, plasma osmolality increased 1.89 mOsm/kg. Conclusion: Compared with water, O2water does not limit dehydration for experienced male runners in hot humid conditions
