国内外田径跳跃项群成绩演进轨迹及其动因分析

Achievement evolutionary trace of jump event groups in track and field and its causes at home and abroad

采用文献、数理统计、比较等方法,对1996-2005年世界及中国田径跳跃项群历年各单项前10名的成绩进行分析和处理。结果表明:世界田径跳跃项群各单项成绩处于停滞和下滑阶段,我国田径跳跃项群各单项呈稳步增长的态势;世界田径跳跃项群发展无明显周期规律,我国主要以全运会为周期"波浪式"向前发展;不同性别各单项发展速度是极不平衡的,并有各自的演变趋向及发展空间极限。

By adopting the methods of documentary, mathematical statistics and comparation, the paper analyzes the top ten athletes in each jumps in the track and field in the world and China from 1996 to 2005. It discloses that the achievements for each individual event of the jump event groups in track and field worldwide stay at a stagnation or come down. There is a trend of steady development for that in China. This event group develops without obvious periods and rules, but in China, it has been made develop ment further through the National Games. Although the speed of development of each individual event between different sexes are unbalanced, they have their own evolutionary trends as well as the limits of developing spaces.
