Clinical Trial Summary

New data suggests that isometric handgrip training (IHT) might become a novel tool in the treatment of hypertension. The main purpose of this research project is to evaluate the effects of home-based IHT on ambulatory blood pressure in older adults with pre-hypertension and hypertension. Eighty-four older adults with pre-hypertension and hypertension will be randomly distributed to one of three groups: home-based IHT, home-based aerobic exercise training (AET), or attention-control group (CON). Each intervention will have a total duration of 8 weeks. At baseline and after completing the intervention, patients will undergo the following evaluations: 24-hour ambulatory blood pressure, cardiorespiratory fitness, endothelial function, damage and repair, arterial stiffness, inflammatory biomarkers, autonomic function, physical activity levels, dietary intake and quality of life. A qualitative analysis will also be applied to enhance the understanding of the efficacy of this intervention from the patient's perspective.
