AI-Summary

What this Trial Is About

There is strong evidence for the association between sedentary behaviors and cardiovascular diseases such as coronary heart disease and stroke. However, the public currently has no clear guidance on how to limit or interrupt their sedentary behaviors. This study will identify and test the physiological effects of several sedentary behavior interruption strategies and explore the feasibility (i.e., likelihood of an individual performing the requested activities) of those strategies to inform the development of public policy surrounding sedentary behavior interruption. Long-term, the findings of this study will inform a large clinical trial that can test whether sedentary behavior reduction can decrease cardiovascular disease risk.
