摘　　要： 为了探究我国男子三级跳远运动员跨步跳技术落后的原因,采用现场拍摄等研究方法对我国部分优秀男子三级跳远运动员跨步跳当中速度的变化、落地角与起跳角及重心腾起角、摆动腿的摆动、支撑腿的缓冲等相关的数据指标与国外优秀运动员进行比较研究。结果表明:我国运动员跨步跳踏跳过程水平速度损失过大,向上起跳的垂直速度小;踏跳支撑腿膝关节缓冲大,摆动腿后摆不积极,前摆不充分;着地角较小,产生的制动力大。根据分析研究,提出加强运动员专项速度素质和专项弹跳能力的训练、强调控制着地点、加强支撑腿的支撑能力和肌肉的退让性工作能力。 The purpose of this research is to explore the reasons for the backwardness of the step technique for China＇s male triple jump athletes. By using the method of on-spot shooting,etc. ,the relative data and indicators of some Chinese elite male triple jumpers are recorded and compared with that of international elite triple jumpers. The indicators include the speed changes of step, the landing angle, the take-off angle, center of gravity flight angle, swinging leg of the swing and the buffer of the support leg. The results show that the Chinese jumpers tend to suffer a great loss of horizontal speed in the step jump process; they have a slower vertical speed in take-off and too big buffer in the knee of the support leg in stepping; there is not enough back swing of the swinging leg and inadequate front swing, and their landing angel is small with too great braking force. Based on the above analysis and research, it is proposed that training of the special speed quality and special bouncing rate of athletes should be strengthened and control of the landing location, the supporting ability of the supporting leg and the flexibility of muscle capacity be emphasized.
