Cardio plus weights cut blood pressure after menopause, but only by a whisker

Blood pressure tends to climb after menopause, and with it the risk of cardiovascular disease, which is why exercise is so consistently recommended to postmenopausal women. Programmes that combine aerobic work with resistance training are popular because they cover endurance, strength and bone in one package. What has been much less clear is how much blood pressure such combined training actually shifts in this specific group, and whether the blood vessels themselves change. This review set out to put honest numbers on both questions.

The authors searched five electronic databases up to November 2020 and included 11 randomised controlled trials of combined aerobic and resistance exercise in postmenopausal women. Results were pooled using a random-effects model, and the review was registered in advance on PROSPERO. Beyond systolic and diastolic blood pressure, the analysis covered brachial-to-ankle pulse wave velocity, a measure of arterial stiffness, and resting heart rate. Subgroup analyses examined age, weight, baseline blood pressure and features of the training itself, such as weekly frequency, weekly minutes and programme duration.

Combined training significantly lowered systolic blood pressure by 0.81 mmHg and diastolic by 0.62 mmHg compared with control: statistically real, but small changes at the group level. Arterial stiffness improved by 1.18 m/s on the pulse wave velocity measure, and resting heart rate fell by 0.22 beats per minute. Subgroup analyses suggested women aged 60 and over, those who were overweight, and those with normal baseline blood pressure were more responsive. Training fewer than 3 times per week, accumulating at least 150 minutes weekly, or continuing for 12 weeks appeared more effective for blood pressure.

The finding confirms the familiar message that exercise nudges blood pressure in the right direction, while sizing that nudge more honestly than the message usually is: fractions of a point on average, smaller than many would assume. The clearer improvement in arterial stiffness is arguably the more interesting signal, since stiffening arteries are part of how cardiovascular risk accumulates with age. Open questions remain over which protocols, and which women, achieve reductions large enough to matter clinically, and the subgroup patterns here need confirming.

If you are postmenopausal and train with a mix of cardio and weights, this is a reason to keep going: the direction of every measured outcome favoured exercise, and the arteries appeared to benefit beyond the pressure reading itself. It is equally a reason not to expect training alone to transform a blood pressure number, since the average change here was under one point. The two ideas coexist comfortably: real benefit, honestly sized.
