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.
Interventions
OTHERAerobic exercise
30 minutes of treadmill exercise at 60-70% of heart rate reserve
OTHERResistance exercise
30 minutes of circuit resistance session at 40% of 1 maximun repetition test
OTHERControl session
30 minutes seated resting

Intervention model description
20 healthy adults, public servants (9W and 11M), randomly underwent three experimental sessions in early morning prior to their work routine: a circuit resistance session at 40% of 1RM, a treadmill exercise session at 60-70% of heart rate reserve and a resting control session.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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. |
| 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. |
