Beverage Hydration Index: Assessment of Four Rehydration Solutions

Not Applicable
Completed
Conditions
Hydration
Registration Number
NCT06272435
Lead Sponsor
University of Memphis
Brief Summary

No studies to date to evaluate the effects of the three different liquid IV electrolyte products on the beverage hydration index (BHI). Therefore, the purpose of this study is to determine the impact of three different LIV products (Hydration multiplier, Sugar Free formulation with Amino Acids, and Sugar Free with allulose) on hydration status in young and active men and women compared to a control (water). The study 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 BHI (the relative amount of urine passed after consumption of a drink compared to water) including time in positive fluid balance, as well as determining electrolyte concentrations, osmolality, specific gravity, and sodium and potassium in urine.

Detailed Description

Many attempts have been made to improve and measure the hydration status of active individuals. 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). This approach seems to work well; however, some debate remains over what the best fluid is to consume, in particular related to the macronutrient type and the specific electrolyte mix.

Primary Outcome Measures
NameTimeMethod
Beverage Hydration Index240 minutes after beverage consumption

Beverage Hydration index calculated as mass of urine collected following control (water) consumption divided by the mass of urine collected following treatment.

Secondary Outcome Measures
NameTimeMethod
Urine Specific Gravity240 minutes after beverage consumption urine

Urine Specific Gravity will be measured via refractometry.

Sodium balance240 minutes after beverage consumption

Sodium Balance will be calculated subtracting total sodium in urine from total sodium consumed in beverage.

Body Mass240 minutes after beverage consumption

Body Mass in kilograms will be measured using a digital scale

Net Fluid Balance240 minutes after beverage consumption

Net Fluid balance will be calculated subtracting total urine collected from total liquid consumed

Mood and Digestive Questionnaire240 minutes after beverage consumption

Subjects will be asked to self-assess their mood and digestive state via a visual analog scale questionnaire with scale 0 (None) to 10 (Extreme)

Urine Potassium240 minutes after beverage consumption

Urine Potassium will be measured in millimoles per liter.

Urine Sodium240 minutes after beverage consumption

Urine Sodium will be measured in millimoles per liter.

Potassium balance240 minutes after beverage consumption

Potassium Balance will be calculated subtracting total potassium in urine from total potassium consumed in beverage.

Urine Osmolality240 minutes after beverage consumption

Urine Osmolality will be measured in milliosmoles per kilogram of water.
