| 摘 要： | 以奥运会、世界锦标赛跳远前8名运动员为研究对象。运用文献资料法、统计法和归纳法,对跳远决赛过程中成功率、各轮次最优成绩的频数、有效成绩的稳定性(变异系数)等反映跳远竞技表现过程稳定性的参数进行分析。结果表明:近年来男女冠军成绩和前8名平均成绩稳定在一定区间;6轮次跳远成功率总体趋势是逐渐降低,前3轮成功率相对高于后3轮,女运动员下降得更为明显,男运动员在1、2、4、6轮表现出相对稳定的成功率;男运动员在6个轮次中最优成绩的频数没有明显差异,而女运动员在各轮次出现最优成绩的频数差异性非常显著;跳远项目有效成绩的稳定性总体较好,而且男女差别不大,参赛环境的变化对稳定性有一定影响。
