The objective of this study was to investigate the characteristics of the submaximal Oxygen Uptake Efficiency Slope (OUES) in a healthy pediatric population. Bicycle ergometry exercise tests with gas-analyses were performed in 46 healthy children aged 7-17 years. Maximal OUES, submaximal OUES, VO(2)peak, V(E)peak, and ventilatory threshold (VT) were determined. The submaximal OUES correlated highly with VO(2)peak, V(E)peak, and VT. Strong correlations were found with basic anthropometric variables. The submaximal OUES could provide an objective, independent measure of cardiorespiratory function in children, reflecting efficiency of ventilation. We recommend expressing OUES values relative to Body Surface Area (BSA) or Fat Free Mass (FFM).
本研究的目的是调查健康儿童群体次极量摄氧效率斜率（OUES）的特征。对46名7至17岁的健康儿童进行了带气体分析的自行车测力计运动测试。测定了最大OUES、次极量OUES、VO₂峰值、V̇E峰值和通气阈值（VT）。次极量OUES与VO₂峰值、V̇E峰值和VT高度相关。发现与基本人体测量变量有很强的相关性。次极量OUES可以提供一种客观、独立的儿童心肺功能测量方法，反映通气效率。我们建议将OUES值表示为相对于体表面积（BSA）或去脂体重（FFM）。
