Schools can effectively increase the amount of MVPA and decrease sedentary time among the students by implementing Active School Day policies. A limitation to this study is that it only measured total school day physical activity; it did not measure which intervention components were more or less beneficial.
About the Study:
Twenty-six classrooms in six schools in Boston were included in the study from February to June 2011 involving 455 fourth and fifth graders. Accelerometer data was collected for five days during baseline and follow up for 201 intervention students and 192 comparison students.
