Overview
Brief Summary
The aim of this project is to conduct a randomised controlled trial to assess the effect of performing isometric exercise using a handgrip dynamometer on blood pressure.
Detailed Description
Recent meta-analyses suggest isometric resistance training (IRT) may be superior to aerobic exercise for lowering blood pressure. A randomised controlled study will be conducted with participants who are either pre-hypertensive, blood pressure between 120/80 and 140/90, or on medication to control their blood pressure. Previous studies have utilised a sedentary control so we intend to use a sham group to determine if it can be used as a working control for future studies.

Eligibility Criteria
Inclusion Criteria
- •Those within the required age limits, both normotensive, pre-hypertensive, and those medicated for blood pressure management.
Exclusion Criteria
- •Younger than 30 years and older than 70 years; those deemed not to have the capacity to voluntarily participate, unable to participate under their doctor's recommendation, or with arthritis or carpal tunnel syndrome who may aggravate their condition with handgrip exercise.
Outcomes
Primary Outcomes
Change in systolic and diastolic blood pressure
Time Frame: Baseline and 8 weeks
Secondary Outcomes
- Compare and contrast blood pressure changes between the 30% maximum voluntary contraction (MVC) hypertensive and 30% MVC normotensive groups(Baseline and 8 weeks)
- Compare and contrast changes in blood pressure between the 5% maximum voluntary contraction (MVC) and 30% MVC hypertensive groups(Baseline and 8 weeks)
