论第29届北京奥运会男子三级跳远运动员比赛时的表现

On Performance of Men’s Triple Jumpers during the XXIX Olympic Games in Beijing

运用文献资料法、比较分析法、现场测试等研究方法,对第29届北京奥运会男子三级跳远决赛中运动员的基本情况、前后3跳成绩、成功率、速度变化特征等内容进行研究。结果表明:24～30岁是男子三级跳远运动员展示最佳竞技能力的成熟期,第2、3跳是决赛阶段出现最佳成绩的关键跳次,前3跳的成功率普遍高于后3跳,高水平助跑速度仍是取得优异成绩的最关键要素,成绩在17.59 m以上的前3名运动员中,助跑速度均达到8.67 m/s以上。

By means of literature review, comparative analysis, on-the-spot test, etc. , the authors have studied the basic conditions, the first and last three results of jumping, the rate of success and the speed varying characteristics of the men＇s triple jumpers during the final contest of the XXIX Beijing Olympic Games. The following are the results of research. The age of 24-30 is normally the mature stage for men＇s triple jumpers to demonstrate their best competitive ability. The second and third jump are more critical for athletes to achieve best results than other jumps in the final and the success rate of the first three jumps is higher than the last three jumps. It seems that high-level approach-run speed is the key factor to get excellent performance as it is indicated the first three winners,whose jumping results are above 17.59 meters, have reached the approach-run speed of above 8.67m/s.
