YPHV = years from peak height velocity; BMI = body mass index;%FM DEXA = percentage of fat mass using dual x-ray absorptiometry; VO₂max = maximal oxygen consumption; VO₂max-Lean = maximal oxygen consumption adjusted to lean body mass; SD = standard deviation. Independent sample t-test was used for analysis.
