Study Details

Study Description

Brief Summary

The purpose of this study was to determine if rapid changes in hydration status could be determined by urine color expressed in CIE color space

Condition or Disease	Intervention/Treatment	Phase
Dehydration	Other: dehydration and rehydration	N/A

Detailed Description

The study will examine if urine color expressed in CIE color space can reflect hydration status. Hydration staus will be rapidly altered via exercise in the heat.
