The Claim

High-intensity resistance training performed three times per week for 3 to 12 months reduces systolic blood pressure by an average of 3.68 mmHg in middle-aged and older adults with type 2 diabetes, and is the only exercise modality with statistically significant reduction supported by low-certainty evidence.

In plain English

In middle-aged and older adults with type 2 diabetes, performing high-intensity resistance training three times per week for 3 to 12 months lowers systolic blood pressure by an average of 3.68 mmHg, and among exercise types, only this form shows a statistically significant reduction based on low-certainty evidence.

Why this might work

Lifting heavy weights repeatedly causes blood to flow forcefully through arteries during muscle contractions and relaxations. This pushes on the inner lining of arteries, triggering the production of a chemical that makes the artery walls relax and widen. As the arteries become more flexible and open wider, the pressure inside them drops, especially when the heart pumps blood.

  1. Study: Comparative effects of different intensities of aerobic and resistance exercise on glycemic control and cardiorespiratory fitness in middle-aged older patients with type 2 diabetes: a network meta-analysis

    This study found that lifting heavy weights three times a week lowered blood pressure in older adults with type 2 diabetes — and no other type of exercise in the study did. The evidence isn’t super strong, but it’s the only exercise that helped.
