Aerobic Exercise Lowered Systolic Pressure 8.98 mmHg in 1,135 Postmenopausal Women

A systematic review released this week pooled 23 randomized trials of aerobic training in postmenopausal women living with hypertension. Systolic pressure fell by close to 9 mmHg against non-exercising controls, HDL cholesterol edged up, and the individual trials disagreed sharply with one another.

Postmenopausal Women with hypertension who completed at least eight weeks of aerobic exercise finished their programs with markedly lower blood pressure than women assigned to no exercise at all, according to a systematic review and meta-analysis published on 03 November 2026 in BMC Sports Science, Medicine and Rehabilitation. The pooled drop in systolic pressure came to 8.98 mmHg.

The review was assembled by Zhihao Qi, Xiangyun Xu and Xianyang Xin of Capital University of Physical Education and Sports in Beijing, with corresponding author Jun Xie of Shenzhen University of Advanced Technology. The authors state that the work followed PRISMA guidance and was registered in PROSPERO under the identifier CRD420251251858.

PubMed, the Cochrane Library, Web of Science and Embase were searched from inception to January 2, 2026. Eligible studies were randomized controlled trials running at least eight weeks, in women who met the diagnostic criteria for hypertension, with control groups that received no exercise.

Twenty-three trials cleared those rules, contributing 25 comparisons and 1,135 postmenopausal women in total. Pooled across them, aerobic exercise reduced systolic pressure by 8.98 mmHg (95% CI −11.83 to −6.12) and diastolic pressure by 4.64 mmHg (95% CI −6.31 to −2.97).

What the 23 Trials Asked of Participants

The entry rules were narrow in two useful ways. Participants had to be postmenopausal women who met the review definition of hypertension, set at systolic pressure of 130 mmHg or above and diastolic pressure of 80 mmHg or above. Interventions had to be aerobic exercise, or programs built predominantly on aerobic training.

The eight-week floor matters as well. Blood pressure responds to training over weeks rather than days, so short pilot studies can register changes that have not yet stabilized. By requiring two months of exercise, the review limited itself to trials in which postmenopausal women had time to accumulate a training effect.

Control groups received no exercise. That design choice makes the comparison cleaner than a trial pitting one program against another, though it also means the pooled figures describe exercise against inactivity rather than exercise against an alternative therapy.

The Blood Pressure Numbers for Postmenopausal Women

Systolic pressure carried the largest and most quotable effect: a mean difference of 8.98 mmHg, with a confidence interval running from 11.83 mmHg down to 6.12 mmHg of reduction. The interval never crosses zero, which is why the authors describe the reduction as clinically meaningful for postmenopausal women in their conclusion.

Diastolic pressure moved less, at 4.64 mmHg, with an interval of 6.31 to 2.97 mmHg. The ratio between the two is typical of aerobic training studies, where the systolic number tends to shift further than the diastolic one.

Lipids Moved Less, and Less Convincingly

HDL cholesterol rose by 0.10 mmol/L, with a confidence interval of 0.04 to 0.17. That is a real signal but a small one, and the review flags moderate heterogeneity behind it, with I² of 50.3 percent.

LDL cholesterol is the weaker half of the story. The pooled estimate was a reduction of 0.11 mmol/L, but the interval ran from 0.30 mmol/L of reduction to 0.07 mmol/L of increase. Because that range includes no change at all, the authors call the LDL result inconclusive and downgrade it for imprecision.

Readers used to seeing exercise framed as a lipid treatment should sit with that distinction. In this body of trials, the pressure effect in postmenopausal women is the firm finding and the cholesterol effect is partial.

Why the Trials Disagreed With Each Other

The heterogeneity statistics are hard to miss. I² reached 80.9 percent for systolic pressure and 74.8 percent for diastolic pressure, meaning most of the variation between trial results reflects genuine differences between studies rather than chance.

Part of that spread appears to be the exercise itself. The review reports that exercise modality was associated with differences in blood pressure responses, with a between-group P value below 0.0001. The abstract does not name which specific modality produced the largest reduction, so the ranking question stays open.

Publication bias, at least, did not look like a driver. Begg and Egger tests both returned P values above 0.05, which the authors read as no significant evidence of small-study distortion in this set of trials.

Starting Pressure Predicted the Size of the Drop

One meta-regression result deserves attention. Higher baseline diastolic pressure was associated with greater reductions in diastolic pressure, with a coefficient of −0.31 and a P value of 0.004.

That pattern is familiar across blood pressure research and it has a practical reading: pooled averages understate what happens to the participants who start highest and overstate what happens to those who start near the threshold. Postmenopausal women entering a trial at 95 mmHg diastolic are not the same test case as those entering at 81 mmHg.

How It Sits Beside Earlier Exercise and Pressure Research

Trials of exercise and blood pressure have accumulated for decades, but most of the large pooled analyses mix men and women, and mix hypertensive with normotensive volunteers. Restricting the question to postmenopausal women with an established diagnosis is the contribution here, because it removes two sources of confusion in one step.

The background the authors offer for that focus is hormonal. They note that postmenopausal women experience a decline in estrogen levels, which weakens vascular protection, and that framing is why the population is treated as distinct rather than as a subgroup of adults in general.

What the review cannot do is rank itself against drug therapy or diet. No head-to-head comparison of that kind was eligible, because control groups had to be non-exercising. The result is a clean estimate of a narrow question, which is both its strength and the reason it answers less than a casual reading might suggest.

What the Review Can and Cannot Tell Postmenopausal Women

Read conservatively, the review supports a modest claim: in trials of at least eight weeks, aerobic exercise lowered blood pressure in postmenopausal women with hypertension more than doing nothing did, and it nudged HDL cholesterol upward. It does not establish a best modality, a best dose, or a timeline.

It also cannot speak to medication. Participants in these trials were women with hypertension, and the review does not report how many were taking antihypertensive drugs, so the pooled numbers should not be read as a substitute for prescribed treatment. Our earlier report on how interval training interacts with antihypertensive medication covers that question directly.

For readers who want the general-population picture, the site has previously covered how often isometric training has to be done to move blood pressure and what aerobic exercise does to blood vessel function. A separate trial examined aerobic exercise after menopause and executive function, a different outcome in a related population.

A few points are worth holding on to, none of them individualized advice:

• The eight-week minimum in this review is a reminder that blood pressure changes are measured in months, not sessions.
• Pooled averages hide variation; people starting with higher readings changed more in these trials.
• Blood pressure and cholesterol did not respond to the same degree, and LDL cholesterol did not respond reliably at all.
• Anyone with diagnosed hypertension should discuss starting or changing an exercise program with the clinician managing it.
