aWilcoxon signed-rank tests with P<.025 (planned comparisons T0 vs T1 and T0 vs T1) considered statistically significant. The Wilcoxon signed-rank test was only undertaken when the Friedman test was significant (P<.05).
bMPA: moderate-intensity physical activity.
cVPA: vigorous-intensity physical activity.
dPA: physical activity.
eMET: metabolic equivalent.
fMVPA: moderate-to-vigorous physical activity.
