The Claim

In middle-aged, obese adults with prehypertension, aerobic exercise reduces blood pressure more than isometric handgrip exercise, and neither exercise modality alters arterial stiffness to a degree that explains the difference in blood pressure response.

How it works
1 study reviewed
In plain English

In middle-aged, obese adults with prehypertension, aerobic exercise lowers blood pressure more than isometric handgrip exercise, but neither exercise changes arterial stiffness enough to account for the difference in blood pressure reduction.

See the scientific wording

The antihypertensive effect of aerobic exercise in middle-aged, obese adults with prehypertension is not mirrored by isometric handgrip exercise, and the two modalities do not differ in their effect on arterial stiffness, suggesting blood pressure changes are not mediated by acute changes in arterial stiffness.

Why this might work

Aerobic exercise makes blood vessels relax by increasing a chemical that tells them to widen, which lowers blood pressure. Isometric handgrip does not do this, and neither exercise changes how stiff the arteries are, so the pressure drop comes from better vessel relaxation, not stiffer or softer arteries.

  1. Study: THE ANTIHYPERTENSIVE EFFECTS OF AEROBIC VERSUS ISOMETRIC HANDGRIP RESISTANCE EXERCISE

    Aerobic exercise like biking lowered blood pressure in obese adults with high blood pressure, but squeezing a handgrip didn’t help—and neither exercise changed the stiffness of arteries. This means the blood pressure drop from biking must be due to something else, not less stiff arteries.
