目的 分析1985-2010年藏族中小学生速度和耐力素质动态变化趋势,为采取有效措施促进藏族学生体质健康提供科学依据。方法 采用1985-2010年全国学生体质与健康调研数据,对藏族7~18岁中小学生速度和耐力素质指标进行比较分析。结果 1985-2010年间,藏族7~18岁学生50 m跑成绩显著提高(P＜0.01,男生提高0.76 s,女生提高0.72 s),1985-1995年成绩提高幅度较大,在2000年有所下降的基础上,2000年以来男、女生成绩均有所好转。耐力素质方面,7~12岁藏族学生50 m×8往返跑成绩显著提高(P＜0.01,男生提高2.99 s,女生提高5.03 s),1995年达到25年间最高,2000年男、女生成绩均明显下降,2000年以来有所好转;13~18岁男生1 000 m跑成绩保持持平,女生800 m跑成绩下降了5.28 s(P＜0.01),1995年以来男、女生成绩均明显下滑,女生尤为明显。结论 1985-2010年间藏族学生速度素质有所改善,但近年来13~18岁学生耐力素质的下降趋势不容乐观。应充分认识到耐力素质下滑的原因,采取有效措施全面提高藏族学生体质水平。
Abstract
Objective To analyze the secular trends on the quality of velocity and endurance among Tibetan primary and secondary school students from 1985 to 2010,and to provide scientific basis for taking effective measures to promote Tibetan students' physical fitness. Method The data collected by Chinese national survey on students' physical fitness and health from 1985 to 2010 were used to analyze the quality of velocity and endurance among Tibetan school students aged 7 to 18. Results From 1985 to 2010,50 m dash improved significantly among Tibetan students (P＜0.01,0.76 s' faster among boys and 0.72 s' faster among girls),which improved by a big margin from 1985 to 1995,then on the basis of decline from 1995 to 2000,all students' performances got better since 2000.As for the quality of endurance,50 m×8 shuttle run improved significantly among students aged 7 to 12 (P＜0.01,2.99 s' faster among boys and 5.03 s' faster among girls).In 1995,all students' performances reached a peak among 25 years,while decreased significantly in 2000,then got better since 2000.1 000 m run remained flat among boys aged 13 to 18,while 800 m run among girls dropped by an average of 5.28 s (P＜0.01).All students' performances declined markedly since 1995,in particular with girls. Conclusion The quality of velocity among Tibetan students improved from 1985 to 2010,but we cannot be optimistic about the downward trend of the quality of endurance among students aged 13 to 18.
