Do men and women maintain physical activity and fitness during and after cardiac rehabilitation?

Official title: Sex Differences in Barriers and Participation in Physical Activity During and Following Cardiac Rehabilitation

Run by Duke University · NCT07214350 · Data updated 2026-11-12

This project will test whether men and women enrolled in cardiac rehabilitation keep up their physical activity and fitness during rehab and in the six months after completing it.

Is this trial a fit for you?

Likely a good fit

Adult patients (18+) who have started cardiac rehabilitation within the past month and can use a smartphone or tablet are the intended participants.

Probably not a fit

Patients with severe mobility limitations, end-stage kidney disease, recent stroke-related impairment, heart transplant or LVAD, those planning to relocate, or anyone with a medical condition that would prevent completing the protocol are unlikely to benefit from participation.

What this trial studies

The SPARC protocol tracks physical activity and functional fitness for adults enrolled in cardiac rehabilitation by collecting data during rehab, immediately after completion, and six months later. Participants complete three in-person study visits, may take part in up to two qualitative interviews, and use a mobile app on their smartphone or tablet to support activity tracking. Fitness testing is done in person and carries common risks such as physical discomfort, falling, or shortness of breath. Investigators will compare activity and fitness patterns by sex to identify whether men and women differ in maintaining gains from cardiac rehabilitation.

Why it matters

Potential benefit: If successful, findings could help tailor cardiac rehabilitation programs so men and women have better long-term activity and fitness outcomes.

How similar studies have gone: Prior observational work has reported sex differences in activity after cardiac events, but this focused longitudinal tracking during and after formal cardiac rehabilitation is relatively novel.
