通过对收集黄庚的比赛技术参数 ,从绝对速度、助跑最后 10 m的分段速度即节奏和快速起跳的能力三大方面与鲍威尔等世界级运动员进行对比分析 ,发现黄庚除绝对速度明显差于对方外 ,助跑最后 10 m的分段速度由于受绝对速度的影响也均低于鲍威尔等 ,且节奏正好与他们相反 ,呈减速趋势即后 5 m的分段速度低于前 5 m的分段速度。另外 ,由于助跑速度利用率偏高 ,起跳垂直速度所占腾起初速度的份额也少于对方 ,而出现垂直速度、腾起角度的差距 ,最终导致跳远成绩低于对方 0 .5 2 m以上的结果。找出黄庚在技术上存在的差距 ,将有利于他今后有针对性的训练 ,进一步提高运动成绩
Through comparing the technical parameters of Huang Geng with the world class athletes such as Powell from the absolute speed, the final 10 m pitch speed that is rhythm and rapid take-off ability, it is found that Huang Geng is significantly worse than the absolute speed On the other side, the final 10 m block speed of the run was also lower than Powell due to the absolute speed, and the rhythm was opposite to them. The deceleration trend showed that the speed of sub-5 m segment was lower than the first 5 m Segment speed. In addition, due to high utilization rate of run-up, take-off vertical speed accounted for less than the share of the beginning of the speed of the other side, and the vertical speed, angle of the gap, eventually leading to long jump score below 0.52 m result. To find out the technical gap between Huang Geng will be conducive to his future targeted training to further enhance the performance of sports
