No results posted yet for this study

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.

Conditions

  • Sedentary Lifestyle

Interventions

BEHAVIORAL

Short breaks

Following baseline testing, participants will attend a 30-minute individual orientation session, during which they will complete a planning worksheet with a research assistant. They will identify specific strategies they will use to accomplish the pre-specified goal (i.e., to take a 1-minute active break every 30 minutes during the workday). They will also identify potential barriers they will face and devise strategies for overcoming them. The intervention will officially start the Monday after the orientation session and will last for 8 weeks. Participants will receive a weekly email containing tips related to reducing sitting time at work. All participants will complete daily activity logs indicating the time and duration of all breaks from sitting across the 8-week intervention.
