Cardio lowers blood pressure by 4.5 points in postmenopausal women

The years after menopause bring hormonal changes that raise risks to both cardiovascular and mental health, which makes this a period where effective, accessible interventions matter most. Aerobic exercise is the obvious candidate, but its effects have been tested across dozens of scattered trials measuring different things. This review set out to pull those trials together and answer a practical question: how much does aerobic exercise actually move blood pressure, cholesterol, triglycerides, anxiety and depression in postmenopausal women? Pooling the evidence gives a far more reliable estimate than any single trial can.

The reviewers searched four databases, PubMed, Embase, SportDiscus and PsycINFO, from inception to December 18, 2024, for randomised controlled trials of aerobic exercise in postmenopausal women. Sixty-one trials qualified, covering 4,100 women, of whom 2,356 were assigned to exercise and 1,744 to control conditions. Two reviewers independently selected studies, extracted data and assessed risk of bias, with a third resolving disagreements. Certainty of the evidence was formally graded, and outcomes covered blood pressure, the lipid profile, triglycerides, anxiety and depression.

Aerobic exercise reduced systolic blood pressure by 4.5 mm Hg and diastolic blood pressure by 2.4 mm Hg compared with control. HDL cholesterol, the kind generally considered protective, rose by 2.4 mg/dL, while LDL cholesterol fell by 3.6 mg/dL and triglycerides by 7.7 mg/dL. Total cholesterol did not significantly change. On the mental health side, anxiety scores improved by a small margin of 0.2 standard deviations, while the effect on depression was not statistically significant. So the cardiovascular picture is consistently positive, and the psychological picture is more mixed.

These results confirm what smaller trials have long suggested and put firmer numbers on it: aerobic exercise reliably improves blood pressure and most of the lipid profile in postmenopausal women. The blood pressure reduction is in the range that matters for cardiovascular risk, though the review itself stresses that these are intermediate markers. The authors call for further research on long-term, hard outcomes, meaning events like heart attacks and strokes rather than numbers on a chart. The null result for depression and the small anxiety effect leave the mental health case less settled than the cardiovascular one.

For a postmenopausal reader, this is about as solid as exercise evidence gets short of outcome trials: regular aerobic activity shifted blood pressure, LDL, HDL and triglycerides in the right direction across a large pooled population. It is a reason to think of cardio as working on the specific risks that rise after menopause, not just general fitness. The mental health findings are worth holding more lightly: a small improvement in anxiety, no clear effect on depression. Nothing here says how much or what kind of cardio is optimal; the trials varied, and this review did not settle that question.
