Sex and Exercise-mode Differences in Post Exercise Blood Pressure and Heart Rate Variability Responses During Workday

Not Applicable

Completed

• Conditions: Hemodynamic; Exercise
• Interventions: Other: Aerobic exercise; Other: Resistance exercise; Other: Control session

• Registration Number: NCT03080636
• Lead Sponsor: Federal University of Uberlandia

Brief Summary

The present study compared the acute effects of Sex and exercise mode on subsequent blood pressure (BP) and heart rate variability (HRV) responses during daily work in healthy adults. All subjects did 3 sessions: aerobic exercise on a treadmill, resistance exercise at the gym and a seated control session.

Detailed Description

Resting blood pressure and heart rate variability are simple and non-invasive methods to evaluate cardiovascular risk after different exercise sessions. Thus, exercise can reduce these risk factors in the short and long term, but these responses can be different between sex in different exercise sessions.

Arm && Interventions

Group	Intervention	Description
Men	Aerobic exercise	11 men randomly underwent three experimental sessions in early morning prior to their work routine.
Men	Control session	11 men randomly underwent three experimental sessions in early morning prior to their work routine.
Women	Aerobic exercise	9 women randomly underwent three experimental sessions in early morning prior to their work routine.
Women	Control session	9 women randomly underwent three experimental sessions in early morning prior to their work routine.
Men	Resistance exercise	11 men randomly underwent three experimental sessions in early morning prior to their work routine.
Women	Resistance exercise	9 women randomly underwent three experimental sessions in early morning prior to their work routine.

Primary Outcome Measures

Name	Time	Method
Heart Rate Variability	Change from baseline Heart Rate Variability components to 15, 30, 45 and 60 minutes after exercise/control session	The HR was recorded by a heart rate monitor (sampling frequency = 1000Hz) in a beat-by-beat basis. HR was registered in a seat position during 15 minutes for each measure.
Resting blood pressure	Change from baseline Systolic and Diastolic Blood Pressure to 15, 30, 45, 60, 210, 360 and 540 minutes after exercise/control session	During all sessions, systolic (SBP) and diastolic blood pressure (DBP) were triplicate measured by an automatic blood pressure analyzer after rest in seated position.
