Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Intervention Model

CROSSOVER

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.
