Aim 1 Key Findings
Key findings of our stratified behavioral bout durations analyses included the following:Sedentary bouts: the treadmill desk group engaged in fewer short-duration bouts of <20 minutes relative to the control and sit-to-stand desk groups after M12, but the sit-to-stand desk group had fewer >60-minute bouts relative to the control and treadmill desk groups after M3, M6, and M12.Standing bouts: the treadmill desk group engaged in more prescribed duration (10-30 min) bouts, relative to controls after M6 and M12, and also more prolonged (>30 min) bouts after M3 and M12, relative to controls and the sit-to-stand desk group. In contrast, the sit-to-stand desk group favored increasing standing in prescribed bouts or shorter (1-10 min) after M3 and M12.Stepping bouts: the treadmill desk group engaged in more bouts of prescribed (10-30 min) or shorter durations (1-10 min) as well as longer durations (>30 min), relative to controls and the sit-to-stand desk group at M3, which was not sustained through M12.
