Physical activity
Adolescents’ daily MVPA was measured using the Actigraph GT3X (ActiGraph LLC). The participants were assigned to wear the accelerometer on their non-dominate wrist for 7 consecutive days for three times (baseline, midpoint, and endpoint) and to remove the device only for water-based activities (e.g., swimming, bathing). The data files were downloaded using ActiLife Software with 10s sampling interval (Version 6.13.3; ActiGraph LLC). Accelerometer data were considered valid only if over 480 min (8h) of recorded data per day for at least 3 days were present [
