Prediction of Maximal Oxygen Uptake by Bioelectrical Impedance Analysis in Overweight Adolescents

摘要

BACKGROUNDMaximal oxygen uptake (VO2max), the gold standard for measurement of cardiorespiratory fitness, is frequently difficult to assess in overweight individuals due to physical limitations. Reactance and resistance measures obtained from bioelectrical impedance analysis (BIA) have been suggested as easily obtainable predictors of cardiorespiratory fitness, but the accuracy with which ht²/Z can predict VO2max has not previously been examined in overweight adolescents.
