| Popis: | INTRODUCTION Cardiorespiratory fitness (CRF) measured by oxygen consumption (V˙O2) during exercise is an important marker of health. The traditional method of indexing V˙O2 to total body mass is suboptimal because skeletal muscle mass (SMM), rather than fat and extracellular fluid, is the main contributor to CRF. The traditional estimating equations for peak V˙O2 in youth do not account for this. Bioelectric impedance analysis (BIA) is a noninvasive method to accurately measure body composition. The objectives of this study were to 1) examine the relationship of body composition indices and peak V˙O2 in healthy children, adolescents, and young adults, and 2) derive an optimized estimating equation incorporating BIA and compare its performance with traditional estimating equations. METHODS A retrospective, cross-sectional, single-center study of patients |
