本文以第32届奥运会田赛远度项目前八名共48名运动员为研究对象,运用文献资料、数理统计、对比分析等研究方法,对运动员的年龄结构、发挥率、成功率以及决定成绩出现的轮次等进行研究。研究结果:①第32届奥运会田赛远度项目前八名运动员年龄在20~39岁之间,平均年龄为27.44岁,各项目平均年龄顺序为链球>标枪>铁饼>三级跳远>铅球>跳远。②田赛远度项目发挥率均在96.4%以上;跳跃项目发挥率高于投掷项目。③各项目前八名运动员成功率在58.33~84.78之间;前三轮成功率明显高于后三轮;投掷项目的成功率高于跳跃项目。④最好成绩第1~6轮次分布频数为:16、17、24、10、15、15;各项目冠军成绩在1~6轮次中的分布频数为:2、2、2、1、0、5。

This paper takes 48 athletes ranking in the top eight in the distance field events of the 32nd Olympic Games as the research object,and uses the methods of literature review,mathematical statistics and comparative analysis to study the age structure,exertion rate,success rate and the number of rounds that determine the performance of the athletes.The study found that(a)the top eight athletes in the field events of the 32nd Olympic Games were between 20 and 39 years old,with an average age of 27.44 years.The average age order of each event was hammer throw>javelin>discus>triple jump>shot put>long jump.(b)The exertion rate of field events is above 96.4%;the play rate of jumping events is higher than that of throwing events.(c)At present,the success rate of eight athletes is between 58.33 and 84.78;the success rate of the first three rounds was significantly higher than that of the last three rounds;the success rate of throwing events is higher than jumping events.(d)The distribution frequency of the 1st to 6th rounds of the best score is:16,17,24,10,15,15;The distribution frequency of champions in each event in 1~6 rounds is:2,2,2,1,0,5.
