Study Details

Brief summary:

The SPARC study will measure physical activity and functional fitness during cardiac rehabilitation, right after completion of cardiac rehabilitation, and 6 months later. This will help investigators learn if men and women maintain physical activity levels and functional fitness differently during and after they complete cardiac rehabilitation. Participants in this study will have three in-person study visits and may complete two qualitative interviews over a 10-month study period. The greatest risks during the study include physical discomfort, falling, and/or shortness of breath during the fitness testing.
