Physical Activity
Conditions
Brief summary
The study is designed to compare two methods of delivering short (\ 10 min) physical activity breaks that will occur during the regular school day for 3 years. Schools will be randomized to deliver physical activity breaks led by either the regular classroom teacher or by a remote instructor through a video in the classroom. Both delivery methods will promote a variety of whole body movements using large muscle groups. The schools will not be able to choose which group (regular teacher or remote instructor) they will be part of.
Interventions
BEHAVIORALPhysical Activity Across the Curriculum
Activity breaks will be designed for delivery in the classroom without reconfiguration of the classroom space. Activities will emphasize whole body movements, using large muscle groups. Each break includes multiple activities. Each activity lasts about 2 minutes. There will be a total of about 20 minutes of physical activity done each school day.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Moderate-to-vigorous physical activity (MVPA) time during activity breaks | Year 3 | Measure will be calculated as the average number of minutes of moderate to vigorous physical activity (MVPA) during the period of activity breaks. Measure will be captured using an accelerometer. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| MVPA time during the school day | Year 3 | Measure will be calculated as the average number of minutes of moderate to vigorous physical activity (MVPA) during the school day. Measure will be captured using an accelerometer. |
| Total daily MVPA | Year 3 | Measure will be calculated as the average number of minutes of moderate to vigorous physical activity (MVPA) during the entire day. Measure will be captured using an accelerometer. |
| Body mass index (BMI) | Fall Semester Year 1 | Weight and height will be combined to report BMI in kg/m\^2. |
| Energy expenditure of activity breaks | Year 2 | Calculated as the number of calories used during a classroom activity break. |
