Title: The Effects of Short, Frequent Breaks in Sitting Versus Longer, Planned Breaks in Sitting on Sedentary Behavior and Metabolic Health Among Inactive Females Working Sedentary Jobs
Brief Summary: The purpose of this study is to determine whether varying the frequency and length of activity breaks during the workday will differentially impact sedentary behavior and health outcomes. Participants will be randomly assigned to take short, frequent breaks (i.e., 1 minute every half hour) or longer, planned breaks (i.e., two 15-minute walks) from sitting during the workday. They will be instructed to follow the assigned protocols for an 8-week intervention and the effects of their participation on sedentary behavior and a variety of health outcomes will be assessed. The investigators anticipate participants in both intervention arms will demonstrate significant reductions in daily sitting time, bit do not have an a priori hypothesis regarding the relative effectiveness of each approach.
