A Study to Objectively Measure Physical Activity and Sedentary Behavior During Cardiac Rehabilitation

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess exercise patterns during home-based or center-based cardiac rehabilitation participation.

Detailed Description
-----------------
Participants enrolled in either home-based or center-based cardiac rehabilitation will be instructed to wear an accelerometer device for 7-days at baseline, 4-weeks, 8-weeks, and 12-weeks, to objectively measure their physical activity level during the cardiac rehabilitation program. A questionnaire will also be completed by the participant at baseline and 12-weeks to subjectively measure their physical activity level, based on self-report activities over the previous 7-days. Enrollment in home-based versus center-based cardiac rehabilitation will be based on the availability of cardiac rehabilitation facilities and/or patient preference. There is no random allocation or assignment to groups by the study team.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in minutes spent in moderate-vigorous physical activity, measured by accelerometry | Change in minutes at a moderate-vigorous activity intensity are objectively measured by an accelerometer device that senses movement. The device captures the number of minutes a participant spends in moderate-vigorous activities per day, and will be worn by the participant for 7-days. A higher number of minutes per day indicates a greater physical activity level. | Baseline, 4-weeks, 8-weeks, and 12-weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in minutes spent in moderate-vigorous physical activity, measured by questionnaire | Change in minutes at a moderate-vigorous activity intensity are subjectively measured (self-reported) using the International Physical Activity Questionnaire (IPAQ). The IPAQ captures the number of minutes a participant spends in moderate-vigorous activities per day, based on participant's reporting of the previous 7-days. A higher number of minutes per day indicates a greater physical activity level. | Baseline, 12-weeks | 
| Change in minutes spent in inactive (sedentary) behavior, measured by accelerometry. | Change in minutes spent in inactive (sedentary) behavior, measured by an accelerometer device that senses movement. The device captures the number of minutes a participant spends inactive per day, and will be worn by the participant for 7-days. A higher number of minutes per day of inactive time indicates increased sedentary behavior. | Baseline, 4-weeks, 8-weeks, and 12-weeks |
