Moderate-to-vigorous physical activity (MVPA) was derived from Actigraph using Freedson adult cutoff (1952 counts/min). A valid day contained a minimum of 8 valid hours of data. To be included in the analyses, participants were required to have at least 4 valid days including one weekend day (7-day) or at least 3 weekday days (weekday in-school and weekday after-school) or at least one weekend day (weekend).

Intrinsic motivation scores ranged from 1-7.
