Accelerometry-Derived Physical Activity of First Through Third Grade Children During the Segmented School Day

摘要

BACKGROUNDSchools should provide children 30 minutes/day of moderate-to-vigorous-physical-activity (MVPA). Determining school day segments that contribute to children's MVPA can inform school-based activity promotion. The purpose of this paper was to identify the proportion of children accumulating 30 minutes/day of school-based MVPA, and to identify school day segments' contribution to children's MVPA.
