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

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.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Able to practice aerobic and resistance exercise at moderate intensity;
  • Men and women;
  • Normotensive, pre-hypertensive or hypertensive stage 1.

Exclusion criteria

  • Renal pathologies;
  • Using beta blockers;
  • History of stroke or acute myocardial infarction;
  • Smokers.

Treatment and study plan

Aerobic Exercise

Other

30 minutes of treadmill exercise at 60-70% of heart rate reserve

Resistance Exercise

Other

30 minutes of circuit resistance session at 40% of 1 maximun repetition test

Control Session

Other

30 minutes seated resting

Primary outcomes

  1. 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.

  2. 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.
