  1. BMI = body mass index, VO2max = maximal oxygen consumption, HRmax = maximal heart rate. Groups are separated by percentile rank of VO2max. Low fit group = <10 MET, Moderate fit group 10–13 MET, High fit group >13 MET. * Significant difference from low fit group, § significant difference from moderate fit group.
