世界优秀男子三级跳远运动员跨步跳技术中生物力学参数及其运动成绩间的灰色关联分析

Gray correlative analysis between biological mechanics parameters of the triple jump contestant stride jumpers in the technology of the world elite men and their achievements

运用灰色关联分析法对世界优秀男子三级跳远运动员跨步跳技术中生物力学参数及其运动成绩间的关系进行分析。结果发现,水平速度是跨步跳阶段决定最终成绩的关键性因素,其次是跨步跳距离;而最小膝角和单脚支撑时间也是影响其最终成绩的重要因素。

With the gray connection analytic method,it analyzed the world elitc men triple jumpers in the technology of the biological mechanic parameters and the movement result relations.The result discovered that the level speed is the stride jumps the stage decision final result crucial factor,next is the stride jumping distance;But the most geniculum angle and the single foot support time also affect its final result.
