Design outcomes

Primary

Measure	Time frame
1. Change from baseline (0-week) to post-intervention (12-weeks) in accelerometer-measured Total Physical Activity (LPA + MVPA), measured in minutes per day. 2. Change from baseline (0-week) to post-intervention (12-weeks) in accelerometer-measured frequency of 30-minute sedentary bouts.	—

Secondary

Measure	Time frame
1. Change from baseline (0-week) to post-intervention (12-weeks) in accelerometer-measured daily walking steps. 2. Change from baseline (0-week) to post-intervention (12-weeks) in accelerometer-measured Light Physical Activity (LPA), in minutes/day. 3. Change from baseline (0-week) to post-intervention (12-weeks) in accelerometer-measured Moderate-to-Vigorous Physical Activity (MVPA), in minutes/day. 4. Change from baseline (0-week) to post-intervention (12-weeks) in accelerometer-measured total Sedentary Time (ST), in minutes/day. 5. Change from baseline (0-week) to post-intervention (12-weeks) in accelerometer-measured total time (minutes) in 30-minute sedentary bouts. 6. Change from baseline (0-week) to post-intervention (12-weeks) in accelerometer-measured number of 1-minute sedentary breaks per day.	—
