目的建立符合上海市儿童青少年生长发育特点的耐力跑参考值及曲线,为监测该地区儿童青少年心肺耐力变化提供参照。方法以2014年上海市学生体质与健康调研6个区15 308名7~18岁学生为样本,用LMS法建立年龄别耐力跑百分位数值。结果获得上海市中小学生耐力跑百分位数值P_3,P_5,P_(10),P_(15),P_(25),P_(50),P_(75),P_(85),P_(90),P_(95),P_(97)及曲线。2014年上海市7~12岁男、女生耐力跑水平均呈上升趋势,13~18岁男、女生耐力跑水平呈先上升后下降趋势。各年龄组耐力跑的P85,P95均高于全国同期水平。耐力跑百分位数曲线呈现性别、年龄特征,7~12岁男女生百分位数曲线基本一致,13~18岁男生百分位数曲线呈持续性上升,而女生13~15岁上升,15岁之后曲线下降,17~18岁曲线略有上升。结论上海市儿童青少年耐力跑百分位数存在性别差异,儿童青少年耐力跑百分位数曲线图为本地区儿童青少年功能水平测量提供了一种直观评价方式。
Objective To establish a reference value and curve of endurance running in line with the characteristics of growth and development of children and adolescents in Shanghai and provide references for monitoring the cardiorespiratory endurance changes of children and adolescents in this area. Methods A total of 15,308 students aged 7-18 years from 6 districts in Shanghai Physical Fitness and Health Survey were enrolled in this study. The LMS method was used to establish the age-specific endurance run-out percentile. Results The endurance percentile values P_3, P_5, P_ (10), P_ (15), P_ (25), P_ (50), P_ (75), P_ (85) , P_ (95), P_ (97) and curve. In 2014, the endurance levels of boys and girls aged from 7 to 12 years in Shanghai showed an upward trend, and the endurance levels of boys and girls aged 13 to 18 were increased first and then decreased. Endurance runners of all age groups P85, P95 are higher than the national average. The curve of percentile of endurance ran showed gender and age characteristics, and the percentile curves of boys and girls aged 7 ~ 12 were basically the same. The percentile curves of boys aged 13 ~ 18 continued to increase, while the percentage of girls aged 13-15 increased, After the 15-year curve decreased, 17 to 18-year-old curve increased slightly. Conclusions There is a gender difference in the percentile of endurance run of children and adolescents in Shanghai. The curve of percentile of children and adolescent endurance run provides an intuitive evaluation method for measuring the functional level of children and adolescents in this area.
