| 摘 要： | 采用文献资料研究、数理统计和逻辑分析等方法,对第13届世界田径锦标赛投掷项目运动员的年龄、身体形态、投掷成功率、比赛发挥、不同投掷次数中出现决定成绩的人数进行统计分析。结果表明,参赛运动员平均年龄为26.64～29.36岁,男子平均年龄稍大于女子;投掷项目男子运动员平均身高在1.87～1.95m之间,呈现出高大化发展特征。资格赛运动员的投掷成功率为79.83%,3次试投的成功率依次下降;决赛阶段运动员投掷的平均成功率为74.57%,6次不同试投的成功率呈现高低交错的"锯齿"状。投掷项群运动员的比赛发挥存在着项目差异,资格赛中,铅球运动员的平均发挥率最高,铁饼运动员发挥率最低;决赛阶段,运动员的发挥率均高于资格赛。资格赛运动员3次试投出现决定成绩的概率分别为44.99%、26.57%和28.44%,呈现出第1次试投成功率和发挥率最高的特点。
