Hemodynamic Effects During Land vs Water Exercise for Older Adults With Orthostatic Hypotension

Not Applicable

Completed

• Conditions: Orthostatic Hypotension
• Interventions: Behavioral: Land exercise; Behavioral: Water exercise

• Registration Number: NCT05233865
• Lead Sponsor: University of Texas at Austin

Brief Summary

The purpose of the study is to understand how blood pressure, heart rate, and symptoms of low blood pressure (such as dizziness or nausea) are affected by positional changes and exercise when on land or in the water for people who tend to experience orthostatic hypotension.

Arm && Interventions

Group	Intervention	Description
Land condition	Land exercise	Participants blood pressure, heart rate and self-reported symptoms (such as dizziness) will be collected multiple times during sitting, standing, and walking conditions when on land.
Water condition	Water exercise	Participants blood pressure, heart rate and self-reported symptoms (such as dizziness) will be collected multiple times during sitting, standing and walking conditions when in a pool.

Primary Outcome Measures

Name	Time	Method
Systolic blood pressure (mmHg)	<1 minute upon standing	Blood pressure will be taken with an automated blood pressure device
Diastolic blood pressure (mmHg)	<1 minute upon standing	Blood pressure will be taken with an automated blood pressure device
Self-reported orthostatic hypotension symptoms	2 minutes	A self-reported instrument assessing symptoms from low blood pressure experienced upon standing or after prolonged upright activities. Possible scores range from 0 (no symptoms) to 10 (worse possible symptoms)
