Squeeze your way to better health? handgrip exercise trial for seniors with high blood pressure
NCT ID NCT07648498
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a short, supervised handgrip exercise program is practical and enjoyable for older adults (65+) with high blood pressure. Thirty participants will do handgrip exercises twice a week for 4 weeks. Researchers will check if the program is easy to stick with and if it leads to any improvements in blood pressure and cognitive function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- isometric handgrip exercise using the Zona Plus device
- What this could lead to
- If this works, it could offer a simple, low-cost exercise option to help older adults manage blood pressure and potentially boost cognitive function.
- What could go wrong
- This is a very small, early feasibility study with only 30 participants. It is not designed to prove the exercise works, only that it is acceptable and practical. Results may not apply to all older adults.
