  1. VO2 max (ml/kg/min) values calculated with the Leger formula (28). The values in bold indicate statistical significance at p < 0.05. P values are from parametric test as all variables are normally distributed.
  2. BMI body mass index, VO2 max maximal oxygen intake, LDL-c low-density lipoprotein cholesterol, HDL-c high-density lipoprotein cholesterol.
