NCT07658820

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Time to completion of 5 kilometer cycling time trial

    cycling performance expressed as time to completion.

    Five minutes after completion of the two-hour cycling protocol

  • Psycho-motor Vigilance test

    Psycho-motor Vigilance test measured by reaction time in milliseconds

    Five minutes after completion of the 5-kilometer cycling test

Secondary Outcomes (2)

  • Plasma Osmolality

    Plasma osmolality at 0, 30, 60, 90, and 120 minutes of the 2-hour steady cycling, at the end of the 5-kilometer cycling time trial, and within 2 minutes after the cognitive test.

  • Carbohydrate oxidation rate during exercise

    At minutes 15, 60, and 120 of the 2-h steady-state cycling exercise
