中国五大少数民族2014年7~18岁学生耐力素质现状

了解我国五大少数民族2014年7~18岁学生耐力素质现状,为制定干预措施和提高少数民族学生耐力素质提供科学依据.方法 选取2014年全国学生体质与健康调研中蒙古族、回族、维吾尔族、壮族和朝鲜族7~18岁学生作为研究对象,以同年龄、同性别全国汉族学生的耐力跑测试时间的均值和标准差计算Z评分;将耐力跑测试时间≤同年龄、同性别全国汉族学生的耐力跑测试时间第25百分位(P25)时间值确定为耐力素质好.结果 2014年五大少数民族7~12岁学生耐力跑时间男生在120.7~ 132.4 s之间,女生在126.4~ 143.7 s之间,男、女生均以蒙古族学生时间最短,维吾尔族学生时间最长(P值均<0.05);13~15岁学生耐力跑时间男生在272.3~ 309.1 s之间,女生在257.3~286.4 s之间,男、女生均以蒙古族学生时间最短,男生以壮族时间最长,女生以维吾尔族时间最长(P值均<0.05);16~18岁学生耐力跑时间男生在251.1 ~ 282.7 s之间,女生在251.5~271.7 s之间,男生以蒙古族时间最短,女生以回族时间最短,男、女生均以朝鲜族时间最长(P值均<0.05).五大少数民族男生Z评分在-0.29~0.30之间,蒙古族<回族<壮族<维吾尔族<朝鲜族(F--141.236,P<0.05);女生Z评分在-0.10~0.75之间,蒙古族<回族<壮族<朝鲜族<维吾尔族(F=270.137,P<0.05).五大少数民族男生耐力素质好检出率在16.2%~37.0%之间,壮族<维吾尔族<朝鲜族<回族<蒙古族(x2=430.060,P<0.05);女生检出率在10.3% ~ 26.5%之间,维吾尔族<壮族<朝鲜族<回族<蒙古族(x2=272.290,P<0.05).结论 五大少数民族中蒙古族学生耐力素质最高,且高于全国汉族学生;回族学生耐力素质接近全国汉族学生;维吾尔族女生耐力素质低于其他民族学生.

Analysis epidemic status of the physical endurance among Chinese students aged 7-18 years of five ethnic minorities in 2014

Objective To explore the physical endurance among Chinese students of five ethnic minorities aged 7-18 years,and to provide a scientific basis for making interventional measures and improving their endurance.Methods Students aged 7-18 years from Mongolian,Hui,Uygur,Zhuang and Korean ethnic minorities were selected to participate in the 2014 Chinese National Survey on Students' Constitution and Health.The mean and standard deviation of the endurance running time of same gender and age were used to calculate Z score.Good physical endurance was defined as endurance running time ≤P25 of same gender and age.Results The endurance running time of boys aged 7-12 was between 120.7 s and 132.4 s,the girls' was between 126.4 s and 143.7 s.Among the five ethnic minorities,Mongolian students ranked the last both in boys and girls and Uygur students ranked the first both in boys and girls(P<0.05).The endurance running time of boys aged 13-15 was between 272.3 s and 309.1 s,the girls' was between 257.3 s and 286.4 s,and among the five ethnic minorities,Mongolian students ranked the last both in boys and girls Zhuang students ranked the first in boys and Uygur students ranked the first in girls(P<0.05).The endurance running time ot boys aged 16-18 was between 251.1 s to 282.7 s,the girls' was between 251.5 s to 271.7 s,among the five ethnic minorities Mongolian students ranked the last in boys,Hui students ranked the last in girls and Korean students ranked the first both in boys and girls(P<0.05).The Z score of five ethnic minorities was between-0.29 and 0.30 in boys,Mongolian
