Impact of Significant Weight Loss on Maximal Oxygen Uptake in Obese Children and Adolescents

Abstract

We conclude that relative VO2max mL/kg/min is significantly improved in obese youth after significant weight loss with a VLCD and moderate-intensity, progressive exercise. However, because absolute VO2max L/min was unchanged, this improvement seems to result from the reduction in total body weight as opposed to the effect of the moderate-intensity exercise intervention.
