What this trial studies

This feasibility study tests a mobile health solution that uses AI to tailor exercise prescriptions for older adults, delivered through a wearable device and fitness app. It evaluates feasibility, acceptability, appropriateness, and preliminary efficacy on physical activity, mental health, and quality of life. The study follows a stage 1b NIH framework, focusing on implementation processes, user engagement, and potential signals of benefit. Eligible participants are adults 65 and older who own a smartphone, have internet access, and can safely participate in physical activity. Outcomes will inform refinement of the AI-based intervention before larger trials.
