Study Details

The aim of the present study is to evaluate the effectiveness of a milk permeate-based sports drink on hydration, carbohydrate oxidation, exercise performance, vigilance, and reaction time in the heat. We anticipate that the milk permeate, with 44 g per liter and high sodium and potassium, will lead to better hydration, energy delivery, and physical and cognitive performance.
