摘要
采用Sony录像系统(50 f/s)及高速录像系统(120 f/s)两台摄像机对我国优秀女子三级跳远运动员比赛过程中的助跑与三跳动作过程进行了定点拍摄。通过对动作图像解析与相关技术参数的统计与对比分析,结果发现:目前我国女子三级跳远的助跑速度峰值未能出现在起跳前瞬间或板前3 m(倒数第2步);我国优秀女子三级跳远运动员各跳起跳离地时的水平速度大大低于国外优秀运动员,助跑加速节奏的类型属于"下降型"。为此进一步改进助跑加速节奏,充分发挥助跑水平速度的潜能,是我国女子三级跳远技术改进与提高成绩的关键性问题。
This research, based on China~ female triple jump athletes run up technology and technique of the triple jump process and statistics, the shooting scene to the relevant technical data of foreign athletes, carried out the comparative analy sis between the individuals with the following conclusions ; At present, the Chinese female triple jumpers show the run up speed peak moments before take off or board （penultimate step before 3m）. Run up rhythm accelerate the ＂in type＂. The horizontal velocity taken by China＇s female triple jump athletes when taking off are much slower than that of foreign athletes. Therefore, further activities need to be done to improve run up accelerate rhythm which could give full play to the level of speed. It therefore entail our potential technical training to improve athletic performance.
