Key result
Resistance training significantly lowered systolic blood pressure by 7.25 mmHg (95% CI -14.04 to -0.45; p=0.04) compared to control in physically-inactive postmenopausal women.
Why the study?
The study aimed to examine the literature regarding the effects of resistance training on blood pressure in postmenopausal women.
Does resistance training reduce blood pressure in physically-inactive postmenopausal women not on hormone replacement therapy?
Meta-Analysis
Does resistance training reduce blood pressure in physically-inactive postmenopausal women not on hormone replacement therapy?
Resistance training significantly lowers systolic blood pressure in physically inactive postmenopausal women not undergoing hormone replacement therapy.
RT may lower BP in sedentary postmenopausal women without HRT; extends evidence supporting resistance exercise in this population.
Aim: This systematic review and meta-analysis aimed at examining the literature regarding the effects of resistance training (RT) on blood pressure (BP) in postmenopausal women. Methods: The Pubmed, Scopus, Embase, and BVS databases were accessed by two independent reviewers between July 2020, and June 2021 to search for studies that investigated the effects of RT on BP. The eligibility criteria were determined by the PICOT strategy. P: postmenopausal women, I: RT, in which training variables are presented, C: presence of a control group that does not receive any type of intervention, O: BP measured in both groups, at least before and after the intervention, T: randomized controlled trial. For the studies included in the meta-analysis, we calculated the effects sizes based on the net changes in the systolic (SBP) and diastolic (DBP) BP for a random effect model with a confidence interval of 95% and a statistical significance of p < 0.05. Results: The RT group presented a significantly lower SBP (−7.25 mmHg [95% CI: −14.04, −0.45], p = 0.04), while DBP was not statistically significantly different compared to controlled conditions (−2.54 mmHg [95% CI: −5.52, 0.44], p = 0.09). Conclusions: Physically-inactive postmenopausal women who did not take hormone replacement but performed RT exercise had a lower BP value when compared to the control group.

Bertochi et al. (2022) conducted a meta-analysis in Physically-inactive postmenopausal women not taking hormone replacement therapy. Resistance training vs. No intervention control was evaluated on Systolic blood pressure (SBP) (MD -7.25, 95% CI -14.04 to -0.45, p=0.04). Resistance training significantly lowered systolic blood pressure by 7.25 mmHg (95% CI -14.04 to -0.45; p=0.04) compared to control in physically-inactive postmenopausal women.
