The Claim

Supervised intensive aerobic exercise reduces 24-hour systolic blood pressure variability (SBP-SD) by 0.95 mmHg compared to home-based walking in postmenopausal women with hypertension, and this reduction is associated with improved cardiovascular autonomic regulation, which is linked to a lower risk of stroke and heart attack.

In plain English

In postmenopausal women with hypertension, supervised intensive aerobic exercise lowers 24-hour systolic blood pressure variability by 0.95 mmHg more than home-based walking, and this change is associated with better regulation of heart and blood vessel function, which corresponds to a reduced risk of stroke and heart attack.

See the scientific wording

Supervised intensive aerobic exercise reduces 24-hour systolic blood pressure variability (SBP-SD) by 0.95 mmHg more than home-based walking in postmenopausal women with hypertension, suggesting improved cardiovascular autonomic regulation, which may lower stroke and heart attack risk.

Why this might work

Intense aerobic exercise increases blood flow through arteries, which stretches the vessel walls and triggers the release of a chemical that improves the body's ability to detect and correct blood pressure changes. This allows the brain to better control heart rate and blood vessel tone, resulting in less fluctuation in blood pressure over 24 hours.

  1. Study: Improving cardiovascular autonomic function in postmenopausal women with hypertension: a pilot study of supervised versus home-based aerobic exercise.

    Women with high blood pressure who did supervised aerobic workouts had more stable blood pressure throughout the day than those who walked at home, which means their hearts and blood vessels were working more smoothly. This could help lower their risk of heart attacks and strokes.
