Data presented as percentage or median (interquartile range). BMI indicates body mass index; CRF, cardiorespiratory fitness; DBP, diastolic blood pressure; HDL, high‐density lipoprotein; HOMA‐IR, homeostatic model assessment–insulin resistance; SBP, systolic blood pressure; VO2, peak exercise oxygen uptake; WC, waist circumference.
