NCT04502238

Brief Summary

The primary aim of this study is to assess cardiovascular changes (blood pressure, heart rate, electrocardiogram/ECG) in response to mild fluid-restriction dehydration and subsequent rehydration in healthy young and old people. Secondary aims are to assess changes in body composition, mood, and hunger in response to mild dehydration and rehydration.

Outcome Measures

Primary Outcomes (1)

  • Cardiovascular changes

    Changes in QRS waveforms will be assessed using electrocardiograms (ECG) before and after dehydration (fluid restriction)

    change from baseline to dehydration (+13 hours) and then rehydration (+15 hours)

Secondary Outcomes (3)

  • Changes in perception of thirst and hunger

    change from baseline to dehydration (+13 hours) and then rehydration (+15 hours)

  • Changes in body composition

    change from baseline to dehydration (+13 hours) and then rehydration (+15 hours)

  • Changes in mood

    change from baseline to dehydration (+13 hours) and then rehydration (+15 hours)

Interventions

Study participants will refrain from drinking fluids overnight to facilitate 1-2% fluid loss from baseline

Sampling MethodProbability Sample
Study Population

Healthy (i.e. does not take any regular prescription medications) adults between the ages of 18-70 years, who can walk comfortably on a treadmill for 1-hour (to enhance fluid loss before the rehydration period).

You may qualify if:

  • Healthy (no regular prescription medication usage)
  • Able to walk continuously on treadmill for 60 minutes

You may not qualify if:

  • Confirmed or suspected pregnancy
  • Chronic medical condition
  • Regular prescription medication use
