Summary

The study will examine the impact of the Nuun Sport tablets, as compared to water only, on heart rate, perceived exertion, and related outcomes in male and female runners, during and following the performance of a 60-minute treadmill run.

Detailed description

As discussed in our prior applications (protocol FY2020-327 and FY2021-96), maintaining adequate hydration is essential to optimal health (Perrier, 2017), as well as athletic performance (Nuccio et al., 2017). When individuals exercise (in particular in a warm environment), they can lose excessive amounts of fluids through sweating, along with necessary electrolytes (e.g., sodium, potassium, chloride). With dehydration, individuals may feel sluggish and can experience impaired physical performance. (Kenefick, 2018) Many attempts have been made to improve and measure the hydration status of active individuals (Love et al., 2018). This typically involves the ingestion of fluids leading up to activity (typically plain water), as well as the ingestion of fluids during the activity itself (water, along with a diluted carbohydrate/electrolyte beverage). During aerobic exercise, the shift in fluid (intake versus losses) can affect electrolyte balance, with dehydration and potential adverse effects on performance and health (Perrier et al., 2021; Armstrong et al. 2021). A better understanding of rehydration methods and resultant efficacy would permit selection by an athlete of the optimal method for preventing dehydration to optimize physical performance and reduce potential deleterious effects. It is well-accepted that electrolyte replenishment is of importance, both during and following exercise-to aid in rehydration for subsequent bouts. Electrolytes (sodium in particular) have been used for decades to aid athlete hydration and this has led to the development of various sport drinks-which also include small amounts of carbohydrate (e.g., Gatorade, Powerade). The present study will examine the impact of the Nuun Sport tablets, as compared to water only, on heart rate, perceived exertion, and related outcomes: changes in body mass, changes in plasma volume, post-exercise urine volume, and changes in urine specific gravity in male and female runners, during and/or following the performance of a 60-minute treadmill run.

Interventions

Type	Name	Description
DIETARY_SUPPLEMENT	Nuun Sport Drink	Subjects will consume a total of 24 ounces water and 1.5 tablets of Nuun SPORT. Specifically, subjects will drink 12 ounces of Nuun drink 15 minutes prior to the 60 min run and 4 ounces of Nuun drink at 15 min, 30 min, and 45 min during the run.
DIETARY_SUPPLEMENT	Control	Subjects will consume a total of 24 ounces water. Specifically, subjects will drink 12 ounces of water 15 minutes prior to the 60 min run and 4 ounces of water at 15 min, 30 min, and 45 min during the run.
