Effects of Isometric Handgrip Training Among People Medicated for Hype
Effects of Isometric Handgrip Training Among People Medicated for Hypertension: A Multilevel Analysis

Objective: To examine the longitudinal effects of isometric handgrip (IHG) exercise training on blood pressure using hierarchical linear modelling.

Methods: Data from 43 participants who were medicated for hypertension at the time of training were amalgamated from three previous investigations. In each study, IHG training was completed 3 days/week for 8 weeks at 30% of maximal voluntary contraction and resting blood pressure was assessed at twice-weekly intervals throughout.

Results: Hierarchical linear modelling analysis revealed a linear pattern of blood pressure decline over time with estimated reductions of 5.7 and 3 mmHg reductions in systolic and diastolic pressure, respectively. Participants with higher initial systolic pressure showed greater rates of blood pressure decline (r=−0.67), inferring that individuals with higher blood pressure stand to achieve greater benefits from this method of training.

Conclusions: These results provide further evidence that IHG training lowers resting blood pressure among persons medicated for hypertension.
