在肥胖儿童中完成心肺适能测试存在许多局限性。本研究的目的是确定新的健康积极生活和肥胖研究小组（HALO）的次最大心肺适能测试方案是否为肥胖儿童和青少年提供了与使用经验证的最大和次最大，基于方程的方案在肥胖儿科人群中测量的峰值摄氧量相当的估计。一组肥胖儿童（n = 21;所有≥第95个体重指数百分位数;年龄10-17岁）完成了3项运动测试方案。作为正在进行的队列研究的一部分，完成了测试，并在第二次访视期间以随机顺序完成了2次次最大心肺功能测试。在HALO（r = 0.75，p = 0.001）和Nemeth（r = 0.66，p = 0.001）次最大方案中，观察到的峰值摄氧量（mL·min（-1））与预测的峰值摄氧量之间存在显著相关性。在考虑体重后，HALO峰值摄氧量（mL·kg（-1）·min（-1））的测量值和预测值之间存在类似的相关性（r = 0.54，p = 0.01）。HALO预测的峰值摄氧量值显示出显着的相关性时，对测量值绘制（r = 0.99）。Bland-Altman分析发现最大和HALO次最大方案之间一致（平均偏倚= -201.75 mL·min（-1））。HALO次极量方案的峰值摄氧量估计值与最大心肺功能测试期间峰值摄氧量测量值之间存在显著关系，这支持使用HALO次极量方案作为估计肥胖儿童人群最大心肺功能适应性的有效测量值。考虑到本研究的原则目标证明，鼓励未来在肥胖儿童人群中进行研究，以确认该方案的普遍性。
Many limitations exist with completing cardiorespiratory fitness testing in obese children. The aim of this study was to determine if the new Healthy Active Living and Obesity Research Group's (HALO's) submaximal cardiorespiratory fitness testing protocol for obese children and youth provides a comparable estimate of peak oxygen uptake to that measured using validated maximal and submaximal, equation-based protocols in the obese pediatric population. A group of obese children (n = 21; all ≥95th body mass index percentile; aged 10-17 years) completed 3 exercise testing protocols. Testing was completed as part of an ongoing cohort study and 2 submaximal cardiorespiratory fitness tests were completed, in randomized order, during a second visit. Significant correlations were found between observed peak oxygen uptake (mL·min(-1)) and predicted peak oxygen uptake for both the HALO (r = 0.75, p = 0.001) and Nemeth (r = 0.66, p = 0.001) submaximal protocols. A similar correlation was found, after accounting for body mass, between measured and predicted HALO peak oxygen uptake (mL·kg(-1)·min(-1)) values (r = 0.54, p = 0.01). HALO predicted peak oxygen uptake values showed a significant correlation when plotted against the measured values (r = 0.99). A Bland-Altman analysis found agreement between the maximal and HALO submaximal protocols (mean bias = -201.75 mL·min(-1)). The significant relationships found between estimates of peak oxygen uptake from the HALO submaximal protocol and measures of peak oxygen uptake during maximal cardiorespiratory testing support the use of the HALO submaximal protocol as a valid measure to estimate maximal cardiorespiratory fitness within the obese pediatric population. Given the proof of principle goal of this study, future research in the obese, pediatric population is encouraged to confirm the generalizability of the protocol.
