摘要

心肺适能(CRF)反映了将氧气从大气输送到骨骼肌并利用它来产生能量以支持运动期间肌肉活动的综合能力。峰值摄氧量(VO2)是国际上公认的衡量青少年CRF的标准。有充分的证据表明,在年轻人中,VO2峰值随着性别特异性的增加而增加,同时在一系列年龄和成熟状态驱动的形态和生理协变量中,随着个体特异性变化的时间和速度而变化。然而,最近对从现场测试中预测VO2峰值的兴趣的复苏,以及对VO2峰值与体重成1:1比例的错误解释的持续存在,使对CRF发展的一般理解变得模糊。此外,当比例比例数据与健康相关变量相关时,会产生虚假关系,因此使用这种比例技术混淆了青年CRF与当前和未来健康指标的关系。本文回顾了现有的证据,并得出结论认为,青年CRF的解释和促进年轻人的健康和福祉应该建立在科学事实的基础上,而不是基于有缺陷的方法和似是而非的数据解释的虚构。

Fact and Fiction in youth Cardiorespiratory Fitness
Cardiorespiratory fitness (CRF) reflects the integrated ability to deliver oxygen from the atmosphere to the skeletal muscles and to utilize it to generate energy to support muscle activity during exercise. Peak oxygen uptake (VO2) is internationally recognized as the criterion measure of youth CRF. It is well-documented that in youth peak VO2 increases with sex-specific, concurrent changes in a range of age- and maturity status-driven morphological and physiological covariates with the timing and tempo of changes specific to individuals. However, a recent resurgence of interest in predicting peak VO2 from field test performances and the persistence of fallacious interpretations of peak VO2 in 1:1 ratio with body mass have obfuscated general understanding of the development of CRF. Moreover, as spurious relationships arise when ratio-scaled data are correlated with health-related variables the use of this scaling technique has confounded the relationship of youth CRF with indicators of current and future health. This paper reviews the extant evidence and concludes that the interpretation of youth CRF and the promotion of young people’s health and well-being should be founded on scientific facts and not on fictions based on flawed methodology and specious interpretation of data.
