These are data from the physician questionnaire administered before, at the end of the training, and 3–6 months after

NS not significant, PA physical activity, SD standard deviation, IQR inter quartile range, r effect size measure for Wilcoxon’s signed-rank test, d Coneh’s d effect size measure

^*Significantly different from baseline at p < .001

^aMeasured on a 7-point scale ranging from 1 = Low to 7 = High

^bMeasured on a 5-point scale ranging from 1 = Never to 5 = Always
