Resumen
Isometric handgrip or (wall) squat exercise performed three times per week produces
reductions in systolic blood pressure (SBP) in adults with hypertension. We aimed to
compare these interventions and the potential to retain benefits with one exercise session
per week. We compared blood pressure changes following handgrip and squat
isometric training interventions with controls in a randomized controlled multicentre
trial in 77 unmedicated hypertensive (SBP ≥ 130 mmHg) adults. Exercise sessions
were performed in the workplace and consisted of four repetitions—three sessions per
week for the first 12 weeks (phase 1), and one session per week for the subsequent
12 weeks (phase 2). Office blood pressure (BP) was measured at baseline, post-phase
1 and post-phase 2. Post-phase 1, mean reductions in SBP were significantly greater
in handgrip (–11.2 mmHg, n = 28) and squat (–12.9 mmHg, n = 27) groups than in
controls (–.4 mmHg; n = 22) but changes in DBP were not. There were no significant
within-group changes during phase 2 but SBP was 3.8 mmHg lower in the wall
squat than the handgrip group—a small magnitude but clinically important difference.
While both interventions produced significant SBP reductions, the wall squat appears
to be more effective in maintaining benefits with a minimal training dose. The low
time investment to achieve and retain clinically significant SBP reductions—42 and 12
min, respectively—and minimal cost, particularly of the wall squat, make it a promising
intervention for delivery in public health settings.
