Abstract

Background: Elderly people are particularly affected by rising systolic blood pressure (SBP). We performed a study to test our hypothesis that resting blood pressure (RBP) reducing isometric exercise training (IET) can be delivered in a group setting with older adults.
Methods: Participants (63-88yrs; N=19) completed IET at 30%MVC, 3 days a week for 12-weeks. RBP was measured weekly throughout, plus 6-weeks post-training. Control participants did not engage in IET (N=5). Changes in RBP were assessed using a two-way repeated measures ANOVA.
Results IET induced significant reductions in SBP (-10.5mmHg; P<0.05), but SBP also declined unexpectedly in the control group (-4.5mmHg; P<0.05). DBP declined in the IET group only (-4.7mmHg; P<0.05). There were no significant differences between groups for SBP or DBP (P>0.05). 6-weeks post-training, SBP was still 9.4mmHg below baseline in the IET group only. A unique finding was that the clinically significant RBP reductions persisted for 6 weeks after IET.
Conclusions: Handgrip IET may be an effective anti-hypertensive intervention, which persists for several weeks in older adults, even when training ceases.
