两千米跑视角下新疆六民族男大学生有氧耐力的现状

Aerobic Endurance of Male College Students of Six Ethnic Groups in Xinjiang from the Perspective of 2000-meter Running

关注新疆六民族18-20岁男大学生有氧耐力的现状,为改进体育教学,制定体质与健康干预措施提供科学依据。运用文献资料方法和数理统计法,以新疆K大学2011-2012,2012-2013,2013-2014,2014-2015,2015-2016,2016-2017,2017-2018,2018-2019,2019-2020学年度26336名男性大学生为研究对象,对不同民族和地区进行编码,分析不同学期、民族和地区学生有氧耐力的差异。结果表明:(1)9年17个学期的时间跨度,男大学生2000m跑时间平均值增加了34.1s,增幅6.17%。随着学期的增长,2000m跑时间整体呈现缓慢增加趋势,有氧耐力呈缓慢下降趋势,这与全国19-22岁年龄组学生的耐力素质呈下降趋势一致;(2)不同民族男大学生2000m跑时间平均值范围在529.4-588.6s之间,由长到短排列顺序,汉族>蒙古族>回族>维吾尔族>哈萨克族>柯尔克孜族。汉族男生以588.6s高居榜首,有氧耐力最差。柯尔克孜族男生以529.4s用时最短,有氧耐力最好;(3)新疆籍男大学生2000m跑平均值,南疆大幅低于北疆,反映出南疆学生有氧耐力普遍高于北疆学生。

This paper focuses on the status quo of aerobic endurance of male college students aged 18-20 in six major ethnic groups in Xinjiang,and provides scientific basis for improving physical education teaching and formulating physique and health intervention measures.Using the method of literature and mathematical statistics,26,336 male college students from the academic year 2011-2020 in Xinjiang K University were selected as the research objects.The differences in aerobic endurance of students in different semesters,ethnic groups and regions were analyzed by encoding of different ethnic groups and regions.The results showed that:(1)Over the nine years and 17 semesters,the average running time of male college students in 2000 increased by 34.1 seconds,or 6.17%.With the increase of the semester,the whole 2000-meter running time showed a slow increase trend,and the aerobic endurance showed a slow decline trend.(2)The average 2000-meter running time of male college students of different ethnic groups ranges from 529.4 to 588.6 seconds,in order from long to short,Ethnic Han>Mongolian>Hui>Uyghur>Kazak>Khalkhas.Han male students topped the list with 588.6 seconds and had the worst aerobic endurance.Kirgiz boys had the shortest time of 529.4 seconds and the best aerobic endurance.(3)The average of male college students from Xinjiang in 2000-meter race is significantly lower in southern than in northern,which reflects that the aerobic endurance of students from southern Xinjiang is generally higher than that of students from northern Xinjiang.
