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.

Conditions

Hemodynamic; Exercise

Keywords

Post-exercise hypotension; Aerobic Exercise; Resistance Exercise; Autonomic Stress; Heart Rate Variability; Sex difference

Outcome Measures

Primary Outcomes (2)

• Resting blood pressure

  During all sessions, systolic (SBP) and diastolic blood pressure (DBP) were triplicate measured by an automatic blood pressure analyzer after rest in seated position.

  Change from baseline Systolic and Diastolic Blood Pressure to 15, 30, 45, 60, 210, 360 and 540 minutes after exercise/control session

• Heart Rate Variability

  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.

  Change from baseline Heart Rate Variability components to 15, 30, 45 and 60 minutes after exercise/control session
