Note: Frequencies in brackets represent the proportion of the total sample with data for each variable; Significant between-sex differences (t student or Chi-square; * p < 0.001; ** p < 0.01); a VO2peak (mL·kg−1·min−1) predicted using the Leger et al. equation [27]; b To classify VO2peak, we used the 2011 FITNESSGRAM® standards and healthy fitness zones [28].
