  1. Values are means (SD). aAccelerometer non-wear criteria are minutes of consecutive zero counts without any allowance for interruptions above zero counts (10–90) and ≥60 and 90 min of consecutive zero counts with allowance for 1 and 2 min of interruptions above zero counts (60–1, 60–2, 90–1, and 90–2); PA physical activity, cpm counts per minute, SED sedentary time, LPA light physical activity, MPA moderate physical activity, VPA vigorous physical activity, MVPA moderate-to-vigorous physical activity
