Exercise lowers blood pressure after menopause, and more is not always better

Blood pressure tends to climb through the menopausal transition and afterwards, adding cardiovascular risk at a stage of life when many women are re-evaluating their health habits. Exercise is a standard recommendation, yet guidance rarely specifies which type of exercise, or how much per week, works best for this group. Trials in peri- and postmenopausal women have tested everything from land-based training to aquatic classes at very different weekly volumes. This analysis set out to map the dose-response relationship: how blood pressure changes as weekly exercise dose rises, and whether some modalities outperform others.

The authors searched four databases up to March 2026 for randomised controlled trials of exercise lasting at least 4 weeks in peri- or postmenopausal women. To limit dose misclassification, they calculated weekly dose only from trials reporting frequency, intensity and session duration, expressing it in METs-min per week and adjusting for attendance where reported. Seventy-four trials involving 3,573 women, with a mean age of 59.5 years, were included, and 70 of them enrolled postmenopausal women exclusively. A Bayesian dose-response network meta-analysis was fitted, testing eight candidate curve shapes and retaining the quadratic model as the best fit.

Blood pressure reductions rose with dose and then appeared to level off. The largest predicted drops were 6.70 mmHg systolic at 1,400 METs-min per week and 4.20 mmHg diastolic at 1,500 METs-min per week. Aquatic exercise produced the largest model-estimated point reductions at its highest observed dose of 800 METs-min per week, at 11.63 mmHg systolic and 7.73 mmHg diastolic, but only three trial arms contributed, so the authors label that ranking exploratory. Age, baseline blood pressure and intervention length did not significantly change the results, and the apparent tail-off at higher doses depended on the model used. Certainty of evidence ranged from very low to low.

Exercise guidance around menopause has tended to be generic, and this analysis extends earlier work by putting numbers on the dose curve specifically for postmenopausal women, a group often folded into broader adult populations. The suggestion that benefits plateau rather than climb indefinitely complicates the more-is-better assumption, though the authors stress this curve shape is model-dependent. The aquatic exercise signal is a genuinely open thread, resting on too few trials for a confident ranking. Whether any of this holds for perimenopausal women remains unanswered, since only four of the 74 trials included them.

For postmenopausal women, this is a reason to believe a solid weekly exercise habit is associated with meaningful blood pressure reductions, and that piling on ever more volume may not buy more. The aquatic exercise finding is intriguing rather than conclusive, resting on only three trial arms. Because the certainty of evidence is low and the exact sweet spot depends on modelling choices, the specific figures are better treated as a rough map than a prescription. Perimenopausal women, meanwhile, remain largely unstudied on this question.
