Summary

Dehydration is defined as the state of water deficit due to excessive water losses and/or small water intake. Underhydration is the result of inadequate water intake leading to activation of water hormonal homeostasis, characterized by elevated vasopressin, lower urinary output, and concentrated urine without any measurable changes in total body water. It is well established that dehydration (water deficit) decreases exercise performance and worsens mood, mainly in women. However, the impact of increased water intake in underhydrated individuals on their exercise capacity and mood is not known. The aim of the proposed study is to investigate the impact of increased water intake in underhydrated individuals on aerobic exercise performance and mood in both women and men.

Conditions

• Dehydration
• Mood

Interventions

Type	Name	Description
BEHAVIORAL	Increase water consumption	The underhydrated individuals will be instructed to increase their water intake for one week in order to meet the following two criteria: a) urinate at least 7 times per day and b) have straw-like color urine. A 2-mile run will be completed before and after the 7-day intervention.
BEHAVIORAL	Maintain adequate water consumption	The subjects that are classified as euhydrated will be asked to maintain high water intake for one week to ensure proper hydration. A 2-mile run will be completed before and after the 7-day intervention.
