The Claim
High-intensity interval training reduces 24-hour systolic blood pressure by 5.7 mm Hg and diastolic blood pressure by 4.6 mm Hg in adults with hypertension, with effects comparable to aerobic training.
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 hypertension, high-intensity interval training lowers 24-hour systolic blood pressure by 5.7 mm Hg and diastolic blood pressure by 4.6 mm Hg, with effects similar to those of aerobic training.
See the scientific wording
High-intensity interval training reduces 24-hour systolic blood pressure by 5.7 mm Hg and diastolic blood pressure by 4.6 mm Hg in adults with hypertension, with effects comparable to aerobic training, though evidence is limited by low sample sizes and very low confidence ratings.
Repeated bursts of intense exercise press blood harder against artery walls, which triggers the inner lining of arteries to release a chemical that tells blood vessels to relax. This relaxation lowers the resistance to blood flow, which brings down blood pressure throughout the day and night.
What the research says
1 studyThis study found that doing short bursts of intense exercise with rest in between lowered average daily blood pressure in people with high blood pressure by about 6 mm Hg systolic and 5 mm Hg diastolic — just like the claim says. It’s about as effective as steady cardio, but the results aren’t super precise because not many people were studied.
