我国跳跃类项群优秀运动员竞技表现研究——基于2015年世界田径锦标赛

Research on Competitive Performance of Elite Athletes in China——Based on the 2015 World Track and Field Championships

运用文献资料、录像观察及数据对比分析,对2015年世界田径锦标赛中我国跳跃类项目运动员竞技表现进行研究分析,结果显示:资格赛中,男子撑杆跳高(99.16%)、跳远(98.79%)运动员的平均发挥率最高;女子跳远和跳高运动员发挥率相对较低;进入决赛的男子跳远、跳高及女子撑杆跳高运动员的发挥率均高于资格赛。资格赛中女子跳跃类项目的成功率均低于男子。决赛阶段跳高运动员仍保持100%的成功率,我们还发现远度项目对成功率的依赖程度明显高于高度项目。男女跳高、三级跳远平均成绩变异系数小,展现良好竞技状态;男子跳远在资格赛、决赛中变异系数均较大,发挥不够稳定,但运动员展现了绝对的竞技能力。

A comparative analysis of literature,video observation and data use,on the2015World Athletics Championships in China jumping athletes athletic performance research and analysis,results showed that:in qualifying,men's pole vault(99.16%),(98.79%)the average long jump athletes to play the highest rate;the women's long jump and the high jump athletes play rate low;play finals in the men's long jump,high jump and pole vault rates are higher than the qualifying.The success rate of women's jumping events in qualifying tournament are lower than that of men.The final stage of the high jump athletes still maintain a100%success rate,we also found that the success rate of the project depends on the degree of success is significantly higher than the height of the project.Male and female high jump,three jump average coefficient of variation is small,show a good competitive state;the men's long jump in the qualifying finals,the coefficient of variation was large,not stable enough to play,but the absolute competitive ability of athletes.
