Statistical analyses
We used the AHA for sample size calculation (α = 0.05, 1 − β = 0.8, δ = 0), which indicated a minimum requirement of 16 participants per group. Considering the likelihood of dropout, we set the sample size to 20 children per group. Baseline outcome measures, accelerometry data, and reported treatment activities were analyzed using T-test or Mann–Whitney comparisons. The effects of both interventions relative to T1 were tested using one-way RMANOVA (or Friedman RMANOVA).Changes observed between testing sessions in both groups (T2–T1 and T3–T1) were compared using non-inferiority statistics analyses [
