Summary

This study tests whether an AI-driven mobile app, paired with a Fitbit, can deliver personalized exercise plans that older adults find feasible and acceptable. Over 8 weeks, participants aged 65 and older will receive daily and weekly exercise prescriptions tailored to their activity levels and well-being. The study will also explore preliminary effects on physical activity, sleep, mental health, and quality of life.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
AI-powered mobile app (sFitRx) with a Fitbit wearable for personalized exercise prescriptions
What this could lead to
If successful, this could pave the way for a scalable, personalized exercise program that helps older adults stay active, improve mental health, and enhance quality of life.
What could go wrong
This is a small feasibility study with only 20 participants, so results may not apply broadly. It focuses on whether the approach is practical and acceptable, not on proving health benefits.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
