The Claim
Aerobic training reduces 24-hour systolic blood pressure by approximately 4.7 mm Hg and diastolic blood pressure by 2.8 mm Hg in adults with hypertension, based on pooled data from 17 randomized trials.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults with high blood pressure, regular aerobic exercise lowers average 24-hour systolic blood pressure by 4.7 mm Hg and diastolic blood pressure by 2.8 mm Hg.
See the scientific wording
Aerobic training reduces 24-hour systolic blood pressure by approximately 4.7 mm Hg and diastolic blood pressure by 2.8 mm Hg in adults with hypertension, based on pooled data from 17 randomized trials, indicating a clinically meaningful effect on ambulatory blood pressure control that is more reliable than office measurements.
Repeated aerobic exercise increases blood flow along artery walls, which triggers cells lining the arteries to produce more nitric oxide. This gas tells the muscle around the arteries to relax, making the arteries wider. Wider arteries reduce the pressure needed to push blood through them, lowering blood pressure all day and night.
What the research says
1 studyThis study found that regular aerobic exercise like walking or cycling lowers average blood pressure over a full day by about 5 mm Hg systolic and 3 mm Hg diastolic in people with high blood pressure — exactly what the claim says.
