Exercise lowers blood pressure in university professors during subsequent teaching and sleeping hours

Abstract

Background

University professors are subjected to psychological stress that contributes to blood pressure (BP) reactivity and development of hypertension. The purpose of this study was to investigate the effects of exercise on BP in university professors during teaching and sleeping hours.

Methods

Twelve normotensive professors (42.2 ± 10.8 years, 74.2 ± 11.2 kg, 172.8 ± 10.4 cm, 20.1% ± 6.7% body fat) randomly underwent control (CONT) and exercise (EX30) sessions before initiating their daily activities. EX30 consisted of 30 minutes of cycling at 80%–85% of heart rate reserve. Ambulatory BP was monitored for 24 hours following both sessions.

Results

BP increased in comparison with pre-session resting values during teaching after CONT (P < 0.05) but not after EX30. Systolic, diastolic, and mean arterial BP showed a more pronounced nocturnal dip following EX30 (approximately –14.7, –12.7, and –9.6 mmHg, respectively) when compared with CONT (approximately –6, –5 and –3 mmHg).

Conclusion

Exercise induced a BP reduction in university professors, with the main effects being observed during subsequent teaching and sleeping hours.
