The Claim

A six-week supervised moderate-intensity aerobic Zumba program conducted twice weekly significantly reduced resting heart rate by 2.80 bpm, systolic blood pressure by 7.13 mmHg, and diastolic blood pressure by 2.07 mmHg in 15 sedentary university employees, with effect sizes indicating moderate to large practical significance.

In plain English

Twice-weekly supervised Zumba sessions for six weeks lowered resting heart rate and blood pressure in sedentary university employees.

See the scientific wording

A six-week supervised moderate-intensity aerobic Zumba program conducted twice weekly significantly reduced resting heart rate by 2.80 bpm, systolic blood pressure by 7.13 mmHg, and diastolic blood pressure by 2.07 mmHg in 15 sedentary university employees, with effect sizes indicating moderate to large practical significance, suggesting that structured workplace-based aerobic exercise can improve cardiovascular efficiency and reduce blood pressure in sedentary adults.

Why this might work

Regular aerobic exercise increases blood flow through blood vessels, which triggers the lining of the vessels to release a chemical that makes them wider. This reduces the force needed to pump blood, lowering blood pressure. At the same time, the nervous system shifts to a calmer state, slowing the heart rate so the heart does not need to beat as often to maintain normal circulation.

  1. Study: CARDIO-FIT U program: Cardiovascular fitness improvement for university employees

    After six weeks of twice-weekly exercise at work, employees’ hearts and blood pressure got healthier—just like the claim says. Even if it wasn’t exactly Zumba, it was similar kind of workout that helped.
