* Difference (baseline to FU2), all variables were adjusted for their respective baseline value and age. ANCOVA was used to analyse the data. † n = 41 and 30 at the FU2 for the intervention and the control groups, respectively. PA physical activity, CPM counts per min, MVPA moderate and vigorous physical activity, CI confidence interval. FU1 follow-up 1 (conducted immediately after the intervention), FU2 follow-up 2 (conducted six months after the intervention).
