Correction

After publication of the article [1], it has been brought to our attention that the values cited under “indices t1-t0” have been reversed and should be displayed in the opposite order. The corrected Table 1 would appear as follows

Table 1 Mean (1 standard deviation) patient characteristics (*p < .05)

Furthermore, the last sentence of Sport club physical activity (minutes per week) that reads “SCPA decreased by 39.3 min per week from t0 to t1 in the young group (F177 = 15.4, df = 1, p < .001).” should in fact say “SCPA increased by 39.3 min per week from t0 to t1 in the young group (F177 = 15.4, df = 1, p < .001).”
