采用文献资料法、数理统计、比较分析等方法对2008—2014年全国中学生田径锦标赛投掷项目前8名成绩及运动员区域性分布进行了统计分析,对投掷类项目成绩的递进系数、定基、环比发展态势以及运动员的区域性分布进行了研究。结果表明,从递进系数看,女子投掷类项目和男子铅球项目成绩总体呈现增长趋势,男子铁饼和男子标枪成绩总体呈现下滑趋势;女子投掷类项目成绩定基发展总体呈下滑趋势,全国中学生投掷类项目区域性分布都有较大的差异,男女投掷类项目发展较好的前3名省(直辖市)都是北京、吉林、湖南。
By means of literature review, mathematical statistics and comparative analysis, the author made a statistical analysis on the top eight achievements and the regional distribution of throwing athletes in the 2008-2004 National Athletics Championships. The progressive coefficient, Development trend and the regional distribution of athletes were studied. The results show that, judging from the coefficient of progression, the performance of women’s throwing items and the men’s shot put shows an overall trend of increase, while the results of men’s discus and men’s javelin show a downward trend. The performance of women’s throwing items shows a declining trend, The regional distribution of the projects is quite different. The top three provinces (municipalities directly under the Central Government) that have better developed projects for throwing men and women are Beijing, Jilin and Hunan.
