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
目的：系统评价通过20米折返跑测试（20-meter shuttle run test, 20m-SRT）推导儿童青少年峰值摄氧量（VO2peak）预测方程的证据等级。
资料来源：由2名研究者按照系统评价与荟萃分析优先报告条目（PRISMA）的规范流程，独立检索MEDLINE（通过PubMed平台）、ScienceDirect、Web of Science、LILACS及SciELO等电子数据库，检索时限截至2017年9月，检索语言限定为英语和葡萄牙语。
纳入标准：原始研究、可获取摘要、采用20m-SRT推导峰值摄氧量预测方程、研究对象为儿童和/或青少年非运动员、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纳入研究的偏倚风险，采用以下评价标准：样本量、样本特征及统计学分析方法。
资料综合：最终纳入18项研究，共分析15个峰值摄氧量预测方程。纳入研究的样本均为8~19岁的男女青少年及儿童非运动员。Léger方程与Matsuzaka方程的证据等级为高级，其预测相关系数r值分别为0.54~0.90和0.65~0.90。Ruiz方程、Barnett方程及Matsuzaka方程的证据等级为中级，对应的预测相关系数r值分别为0.75~0.96、0.66~0.84及0.66~0.89。
结论：Matsuzaka方程用于儿童青少年峰值摄氧量预测时具有良好的参数表现。尽管现有预测方程未纳入相关因素，但体脂含量与青春期分期均与儿童青少年心肺适能显著相关。
