摘要
运用文献资料调研、数理统计、比较和逻辑分析法,以伦敦奥运会田赛项目比赛成绩前8名,共计128名运动员的竞技表现过程为研究对象,对其竞技表现特征进行比较分析。结果表明,伦敦奥运会田赛项目前8名运动员的年龄为24～32岁,平均27.6岁;克托莱指数平均值方面,投掷高于跳跃,同类项目男子高于女子。男、女项目运动员平均成绩的变异系数有显著性差异,男子项目平均成绩的稳定性明显好于女子。田赛各项目发挥率普遍在97%以上,男子项目高于女子项目。田赛远度项目运动员的总成功率在60.9%～81.1%之间,投掷项目的成功率明显高于跳跃项目;远度项目决赛前3轮、中间两轮和最后一轮的成功率呈递减趋势;6个轮次出现运动员最好成绩的几率均等,没有显著性差异;远度项目对成功率的依赖程度明显高于高度项目。运动员成绩的可重复性,男子远度项目远大于女子、田赛投掷项目好于跳跃项目。
By using the methods of documents, mathematical statistics, comparison and logical a- nalysis, this paper studies the competitive performance of the top 8, the total 128 field athletes in London Olympic Games, and makes a comparative analysis of their competitive performance features. The result shows that the age of the top 8 field athletes participating in London O- lympic Games is between 24;32 years, the average is 27. 6;on the average Quetelet index, throwing events are higher than jump, in similar events men higher than women＇s. There are significant differences in the coefficient of variation of the average scores of the male and the female athletes, the stability of the men＇s average scores is significantly better than the women. The play rates of field events are generally above 97;, men higher than women＇s. The total success rate of distance events athletes is between 60.9 %;81.1%, the throwing events＂ sig- nificantly higher than the jump ; in the distance events, the success rate of the first three, the middle two and the last round shows a decreasing trend;Equal chance of athletes in six rounds for the best results, no significant difference, the dependence of the athletes＂ success rate on the distance events is significantly higher than the height events. On the repeatability of athletes achievement, men＇s distance events ; is much larger than the women＇s, the throwing events＇ is better than the jump.
