Abstract

Background

To date, few studies have analyzed postexercise hypotension (PEH) in hypertensive patients with different levels of physical fitness.

Aim

Therefore, this study aimed to compare PEH in trained and sedentary hypertensive individuals.

Methods

Fifty-one well-controlled hypertensive patients of both sexes were assigned to a trained group [60.4±9.4 years; resting blood pressure (BP)=126.3±5.4/75.0±6.3 mmHg; VO2peak=27.3±4.6 ml kg/min] and 58 sedentary hypertensive patients of both sexes were assigned to a sedentary group (63.1±8.9 years; resting BP=134.1±4.2/82.9±5.8 mmHg; VO2peak=20.6±5.5 ml/kg/min). In a cross-sectional design, the individuals were randomized to perform an aerobic exercise session (treadmill; 40 min; 55% VO2peak) and a control session on two different days in the morning. After each session, participants wore an ambulatory BP device for 12 h.

Results

Although no significant differences were identified in BP after the control session, after the experimental session, the trained participants presented lower values than the sedentary participants for systolic (124.1±6.3 vs. 133.4±5.2 mmHg, P<0.01) and diastolic BP (73.1±4.4 vs. 85.5±6.4 mmHg, P<0.01) over the course of 12 h monitoring. For the trained participants, significant correlations were also identified (P<0.05) between the VO2peak and systolic (R=−0.68) and diastolic BP (R=−0.61) 12 h monitoring.

Conclusion

In conclusion, the training level of hypertensive patients influences PEH.
