The aim of this study was to provide normative data for performance on the 20 m shuttle-run test of cardiorespiratory fitness in English schoolchildren. A total of 7366 10-16 year olds completed the 20 m shuttle-run test. We expressed performance as the number of shuttles completed, test score (shuttles and levels) and estimated peak oxygen consumption (VO2peak). We calculated descriptive statistics for each age-sex group to construct percentile curves and tables. To assess the cardiorespiratory fitness of our sample, we calculated the number of participants who fell below proposed cut-offs for low cardiorespiratory fitness based on either completed shuttles or VdotO2peak. These cut-offs did not agree in terms of frequency of classification. The classification based on estimated VO2peak suggested low fitness was more prevalent in males and that the incidence of low fitness increased with age in both sexes. These are the first normative data for shuttle-run performance in English youth and can now be used to interpret data from this cardiorespiratory fitness test. The two cut-offs used for low fitness did not agree and future research should establish a cut-off for test performance which can predict present or future ill-health.
本研究旨在为英国学童 20 米往返跑心肺适能测试的表现提供规范数据。共有 7366 名 10-16 岁的儿童完成了 20 米往返跑测试。我们将表现表示为完成的往返次数、测试得分（往返次数和级别）和估计的峰值摄氧量（VO2peak）。我们为每个年龄性别组计算了描述性统计数据，以构建百分位曲线和表格。为了评估我们样本的心肺适能，我们根据完成的往返次数或 VdotO2peak 计算了低于低心肺适能建议截止值的参与者人数。就分类频率而言，这些截止值并不一致。基于估计的 VO2peak 的分类表明，男性的低体能更为普遍，而且在两性中，低体能的发生率随着年龄的增长而增加。这是英国青少年 20 米往返跑表现的第一批规范数据，现在可以用于解释该心肺适能测试的数据。用于低体能的两个截止值并不一致，未来的研究应该为可以预测当前或未来健康状况不佳的测试表现建立一个截止值。
