上海市学龄儿童青少年速度素质百分位数参考值及曲线

建立符合上海市儿童青少年生长发育特点的速度素质参考值及曲线,为完善该地区儿童青少年身体素质评价体系提供参考.方法 以2014年上海市学生体质与健康调研黄浦、徐汇、闸北、闵行、奉贤和浦东6区15 422名7~18岁学生为研究样本,用偏度-中位数-变异系数(LMS)法建立年龄别50 m跑百分位数值.结果 2014年上海市中小学生50 m跑成绩随年龄增长不断提高,各年龄组均为男生高于女生,且均高于全国学生同期水平.获得上海市中小学生50 m跑百分位数值P3,P5,P10,P15,P2.5,P50,P75,P85,P90,P95,P97及曲线.男生随着年龄的增长,50 m跑成绩出现了7~8岁、11~13岁2个显著提高时期,17岁以后曲线趋于平稳;女生随着年龄的增长,50 m跑成绩提高最快的是7~9岁,之后幅度逐渐减小,14岁以后曲线趋于平稳.结论 本研究获得的百分位数及曲线图为儿童青少年速度素质测量提供了直观评价手段,完善了本地区儿童青少年身体素质常模参照评价体系.

Percentile normal values and curves of velocity for school-age children and adolescents in Shanghai

Objective To establish the normal values and curves of the velocity of children and adolescents in Shanghai,and to provide a scientific basis for the evaluation of the physical development of children and adolescents.Methods A total of 15 422 students aged 7-18 selected from Huangpu,Xuhui,Zhabei,Minghang,Fengxian,Pudong district in Shanghai in 2014 were investigated about their physical quality and health.And LMS method (Tim Cole) was applied to establish the percentile value of 50 meters.Results Sex age specific percentiles of P3,P5,P10,P15,P25,P50,P75,Ps5,Pg0,P95,P97 and curve of velocity were recorded.The students in primary and middle schools in Shanghai in 2014 have got increasingly great results with the increase of their age,and the boys were better than girls,and the students in Shanghai achieved higher than the national level.Conclusion The percentile narmal and curves provide a visual assessment for school-age children's velocity.
