Peak Oxygen Uptake Responses to Training in Obese Adolescents: A Multilevel Allometric Framework to Partition the Influence of Body Size and Maturity Status

The influence of body size and maturation on the responses in peak oxygen uptake (VO 2 ) to a 12-week aerobic training and nutritional intervention in obese boys (; 10–16 years) was examined using multilevel allometric regressions. Anthropometry, sexual maturity status, peak VO 2 , and body composition were measured pre- and postintervention. Significant decrements for body mass, body mass index z -score, and waist circumference and increments...
