研究概览
简要总结
The purpose of this study is to determine the efficacy of performing "exercise snacks" (short movement breaks throughout the day) on various measures of cardiometabolic health.
详细描述
After being informed about the study and potential risks, all eligible participants who have provided consent will undergo a baseline visit to assess pre-intervention basic anthropometrics, cardiorespiratory fitness, and provide a blood sample. Participants will then be randomized in a 1:1 ratio to one of two groups: 1) Mobility movement breaks (stretching or range of motion exercises); or 2) Cardiovascular movement breaks (designed to raise heart rate). Both groups will be encouraged to perform 3-4 daily movement breaks on at least 3 days of the week with support from an online platform and app that provides video instructions and reminders to complete the movement breaks. After 12 weeks, participants will be asked to return to the lab for the same testing performed at baseline.
