Feasibility of a Community-Integrated Isometric Handgrip Exercise Program and Its Preliminary Effects on Blood Pressure and Cognitive Function in Older Adults (NCT07648498)
🩺 Plain-English Summary (8th-Grade Level)
The goal of this clinical trial is to evaluate whether a short, supervised isometric handgrip exercise program is feasible and acceptable for older adults with elevated blood pressure or hypertension. It will also explore whether this type of exercise may improve blood pressure and cognitive function. The main questions it aims to answer are: * Is this handgrip exercise program practical and acceptable for older adults to participate in within a community exercise setting? * Does participation in the program lead to changes in blood pressure and cognitive function? Researchers will compare two handgrip devices to determine whether the method of delivering the exercise influences feasibility and outcomes. Participants will: * Be randomly assigned to use one of two handgrip devices. * Complete supervised exercise sessions twice per week for 4 weeks. * Perform brief handgrip contractions at a set intensity during each session. * Complete blood pressure and cognitive assessments before and after the program.
