Official Title: Resistance Exercise Modify Cardiovascular Responses of Professors During Teaching and Sleep
Brief Summary: Both work activity and reduced nocturnal dipping of blood pressure are related to increased cardiovascular risk. The aim of the present study was to assess the hemodynamic and autonomic responses of university professors during teaching and sleeping times after different resistance exercise intensities. Ten normotensive professors (33.6±3.4 years, 82.4±12.4 kg; 177.0±7.5 cm) randomly underwent control and resistance exercise before initiating their daily activities. Resistance exercise consisted of a circuit training lasting 40min at 40% and 80% of one repetition maximum test. Systolic blood pressure and diastolic blood pressure as well as heart rate variability indicators in the time and frequency domains (Low Frequency, High Frequency, Low Frequency:High Frequency ratio) were evaluated on resting and 24 hours after the sessions. The average day-time, night-time and nocturnal blood pressure fall of systolic blood pressure and diastolic blood pressure were calculated.
