Acute effect of bodyweight-based strength training on blood pressure of hypertensive older adults: A randomized crossover clinical trial

Abstract

ABSTRACT Background: Strength Training (ST) reduces the cardiovascular risk of hypertensive elderly people; however, there is a need for efficient and low-cost ST programs that aim to reduce blood pressure (BP) in elderly people with adherence and affectivity in this population. Objective: Evaluate the acute effect on BP and satisfaction with the practice of bodyweight-based strength training (BWST) in hypertensive older adults. Methods: Participants performed a BWST session and a control session (CS). The BWST consisted of six exercises, with three sets of 30 seconds. In the CS, no activity was performed. BP was measured before and at 0, 10, 20, and 30 minutes post-session. Participants’ satisfaction was assessed. Results: Eleven older adults (65.8 ± 4.6 years; 7 men) participated in the study. There was an increase (p = .028) in systolic BP immediately after BWST, returning to baseline values in the intervals 10, 20, and 30 post-section. In the CS there was an increase (p = .009) 30 minutes post-session compared to 20 minutes. Between sessions, a lower systolic BP was found in BWST (−6.54 ± 3.31; p = .048) 30 minutes post-sessions. For satisfaction, 82% of participants were “totally satisfied” with BWST. Conclusion: The SBP is lower 30 minutes after BWST session than control session, and BWST promoted a pleasant affective response in hypertensive older adults.
