PREDICTIVE EQUATIONS OF MAXIMUM OXYGEN CONSUMPTION BY SHUTTLE RUN TEST IN CHILDREN AND ADOLESCENTS: A SYSTEMATIC REVIEW

ABSTRACT Objective: To systematically review the literature as for the level of evidence of predictive equations of VO2peak through the 20-meter shuttle run test (20m-SRT) in children and adolescents. Data sources: Searches were conducted independently by two researchers, according to the procedures adopted by PRISMA, in the electronic databases MEDLINE via PubMed, ScienceDirect, Web of Science, LILACS and SciELO, for articles published until September 2017 in English and Portuguese. The inclusion criteria were: original studies, abstract available, using predictive equations of VO2peak through 20m-SRT, conducted with adolescents and/or children, non-athletes, and mentioning correlation analysis between predicted and measured VO2peak. The level of evidence of equations was based on the risk of bias of the studies using the following criteria: sample number, sample characteristics, and statistical analysis. Data synthesis: Eighteen studies were selected, in which fifteen equations were found and analyzed. The studies had been conducted with samples composed of subjects of both sexes, aged 8 to 19 years. Equations of Léger and Matsuzaka had their level of evidence classified as high, and estimation ranged between r=0.54-0.90 and r=0.65-0.90. Equations by Ruiz, Barnett and Matsuzaka had their level of evidence classified as moderate, and estimation ranged between r=0.75-0.96, r=0.66-0.84 and r=0.66-0.89, respectively. Conclusions: Matsuzaka’s equation presented satisfactory parameters for estimates of VO2peak in children and adolescents. Although not explored in equations, body adiposity and pubertal stage are significantly associated with cardiorespiratory fitness in children and adolescents.

摘要
研究目的：系统评价通过20米往返跑试验（20-meter shuttle run test, 20m-SRT）建立儿童及青少年峰值摄氧量（VO2peak）预测方程的证据等级水平。
数据来源：由两名研究者严格遵循PRISMA声明的规范流程独立开展文献检索，检索范围涵盖MEDLINE（通过PubMed平台）、ScienceDirect、Web of Science、LILACS及SciELO等电子数据库，检索时限为2017年9月之前发表的英文及葡萄牙语文献。
纳入标准：纳入原创研究、可获取完整摘要、采用20米往返跑试验建立峰值摄氧量预测方程、针对儿童和/或青少年非运动员人群，且报告了预测值与实测峰值摄氧量的相关性分析。
预测方程的证据等级基于对应研究的偏倚风险，结合样本量、样本特征及统计分析三项标准进行评定。
数据综合：最终纳入18项相关研究，共分析得到15个峰值摄氧量预测方程。纳入研究的样本均覆盖8~19岁的男女儿童及青少年。其中Léger与Matsuzaka建立的预测方程证据等级为高水平，其估算相关系数r值范围分别为0.54~0.90与0.65~0.90。Ruiz、Barnett及Matsuzaka建立的预测方程证据等级为中等水平，对应的估算相关系数r值范围分别为0.75~0.96、0.66~0.84及0.66~0.89。
结论：Matsuzaka建立的预测方程在儿童及青少年峰值摄氧量估算中具备良好的参数性能。尽管现有预测方程未纳入相关指标，但体脂量与青春期发育阶段与儿童青少年的心肺适能水平显著相关。
