Abstract: Objective To analyze the trends on the quality of velocity and endurance among primary and secondary Hui students in Ningxia from 1985 to 2005,and to provide evidence for health promotion of students. Methods The data were collected from the Chinese national survey on students' constitution and health (1985,1991,1995,2000,2005,and 2010),and the grades of students' 50 m dash and endurance running were analyzed. Results From 1985 to 2010,50 m dash among boys decreased by 0.006 s meanwhile decreased by 0.24 s among girls.The score in 2005 was still higher than in 1985,but the score in 2010 was lower than in 1985;Endurance running decreased significantly.50 m×8 to and fro running among 7~12 year-old boys and girls decreased by 7.76 s and 6.68 s (P<0.01),1 000 m running among 13~18 year-old boys decreased by 16.38 s (P<0.01),and 800 m running among 13~18 year-old girls decreased by 15.45 s (P<0.01);From 1985 to 1991,students performed better in 50 m dash and endurance running.But the grade was on the decline from 1991 to 2010.The quality of velocity among urban students was better than rural students while the quality of endurance among rural students was better than urban students. Conclusions Over the past 25 years,the physical function and athletic ability of 7-18 year-old students in Ningxia Hui Autonomous Regions are still not optimistic.Comprehensive and effective measures should be taken to promote the status of students' physical health level.

摘要： 目的 探讨1985-2010年宁夏回族7~18岁中小学生速度素质与耐力素质动态变化趋势,为学校体育工作提供科学依据。方法 利用1985-2010年全国学生体质调查资料,对宁夏回族7~18岁中、小学生50 m跑、7~12岁男女生50 m×8往返跑、13~18岁男生1 000 m跑及女生800 m跑数据进行分析比较。结果 1985-2010年的25年间,宁夏回族7~18岁男、女生50 m跑成绩分别下降0.006 s、0.24 s,2005年成绩尚高于1985年,2010年已低于1985年;耐力跑成绩下降明显,7~12岁男、女生50 m×8成绩分别下降7.76 s、6.68 s(P<0.01),13~18岁男生1 000 m跑成绩下降16.38 s(P<0.01),女生800 m跑成绩下降15.45 s(P<0.01)。1985-1991年间,城男、乡男、城女、乡女学生50 m跑、耐力跑成绩显著提高(P<0.05),1991-2010年间,中小学生50 m跑、耐力跑成绩呈下降趋势;12岁50 m跑城市学生成绩高于乡村,50 m×8往返跑乡村学生成绩高于城市,17岁800 m、1 000 m跑乡村学生成绩高于城市。结论 25年间,宁夏回族中小学生速度素质与耐力素质不容乐观,需采取全面有效的措施促进学生体质健康水平的提高。
