Purpose: Acute reduction in blood pressure (BP) following an exercise session is evidenced in controlled settings with formal supervision in hypertensive older populations. This study investigated the effect of a self-selected exercise (SSE)-intensity session on ambulatory BP in hypertensive older women in a “real-world” setting.
Methods: Twenty inactive older women with hypertension (64.9±4.5 years) were included in this randomized, controlled, crossover trial. After baseline assessments, participants performed 30 minutes of an SSE-intensity session on an outdoor track and a control session, separated by 7-10 days. Heart rate (HR), rating of perceived exertion (RPE), and affective response were assessed. Ambulatory BP was monitored for 20 hours following both sessions. Paired t-tests and generalized estimation were used for data analysis.
Results: Participants exercised at 5.1±1.1 km/h, spent ∼90% of the exercise time at moderate–vigorous intensity (≥40% of heart rate reserve). SSE-intensity session was reported as light (RPE 11.0±1.5) and pleasant (affect 3.4±1.2). SSE-intensity session elicited reductions in systolic BP in the first 6 hours postexercise (6.0 mmHg, CI 2.7–9.3 mmHg; P<0.001). Average systolic BP in the 20-hour (−3.4 mmHg, CI −5.9 to −0.9 mmHg; P=0.010) and awake (−4.0 mmHg, CI −6.4 to −1.6 mmHg; P=0.003) periods were lower following SSE-intensity session compared to control session. No differences were observed in average systolic BP during asleep period and diastolic BP during the 20-hour awake and asleep periods between the SSE-intensity session and control session (P>0.05).
Conclusion: An SSE-intensity session elicited a reduction in ambulatory systolic BP in inactive older women with hypertension during awake and 20-hour periods. Also, the SSE-intensity session was reported as light and pleasant.
