Summary

Research has shown that isometric (constant squeeze) exercise training using an isometric handgrip (IHG) device lowers resting blood pressure (BP) in those with and without high BP. The purpose of this study is to explore if IHG training will lower resting BP in people doing cardiac rehabilitation more than doing only cardiac rehabilitation. Once eligibility is confirmed participants will be randomly assigned to one of two groups for the study. One group will do IHG training in addition to cardiac rehabilitation (Group 1), and the other group will do only cardiac rehabilitation (Group 2). Participants assigned to Group 1 will be asked to do IHG training on their own with an inflatable ball three days per week for 12 weeks with intensity set based on rating of perceived exertion (RPE) or rating of effort. Participants will self-measure and report their resting BP to investigators. The acceptability of doing IHG training will also be explored by conducting interviews with participants as will the impact that IHG training may have on psychological wellbeing by administering surveys to participants.
