Study Overview
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.

Outcomes
Primary Outcomes
Heart Rate Variability
Time Frame: 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
Time Frame: 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.
Secondary Outcomes
No secondary outcomes reported
