Squeezing a hand device at home lowered systolic pressure
In Thailand, 30 older adults with hypertension were randomized. After eight weeks, systolic pressure fell more with grip exercises than with no-resistance gripping.
The study, in plain language
The idea fits at home: squeeze a grip device without moving the wrist or arm. In Thailand, a trial randomized 30 people over 60 with hypertension, 15 per group. One group did these exercises for eight weeks, while the other did gripping without resistance.
In the exercise group, systolic and diastolic pressure fell, and the systolic decrease was larger than in the comparison group. Grip strength improved in both groups, so the contrast favoring training was in systolic pressure. There are limitations: a small sample, office blood-pressure measurements on the same arm used for exercise, and no long-term follow-up.
The key idea
After eight weeks of at-home grip exercises, systolic pressure fell more than in the comparison group. Grip strength improved in both.
Something to think about
When an exercise is said to change blood pressure, ask how many people tested it and for how long. Here, it was 30 people over eight weeks.
