Brief Summary

The present study aims to measure the impact of consuming a lower sugar flavored water compared to an equal amount of plain water during exercise on selected rehydration markers in healthy children. Participants will complete two experimental visits designed to examine the differentiating effects of one of two selected beverages (1) lower sugar flavored water beverage and 2) plain water) on certain hydration markers and related perceptual variables during repeated bouts of exercise in a warm environment to induce mild dehydration.

Conditions

Dehydration in Children; Dehydration Following Exertion (Disorder)

Outcome Measures

Primary Outcomes (1)

• Net fluid balance (according to body weight change) from baseline to 3 hours post exercise

  Net fluid balance (according to body weight change) attributable to sweat/body water losses/additions by control of food/beverage intake and urine/fecal output; post 3 hour post exercise body weight (180min) - baseline body weight (0 minutes) = net fluid balance.

  baseline to 3 hours post exercise

Secondary Outcomes (3)

• Hydration status change (according to urine concentration) from baseline to 3 hours post exercise

  baseline to 3 hours post exercise

• Total and compartmental body water change (according to bioelectrical impedance spectroscopy) from baseline to 3 hours post-exercise

  baseline to 3 hours post exercise

• Hydration-related perceptual variable change (thirst, mouth dryness, taste pleasantness) from baseline to 3 hours post-exercise

  baseline to 3 hours post exercise

Other: Lower sugar flavored water

Plain Water

ACTIVE COMPARATOR

Plain water (bottled, spring).

Other: Plain Water

Eligibility Criteria

• Age: 8 Years - 10 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17)

You may qualify if:
