摘　　要：运用SAFMS-T型六维测力平台测量与平面定点录像解析相结合的研究方法,从冲击阶段、积极缓冲阶段、反射蹬伸阶段、动力蹬伸阶段等,对男子三级跳远运动员跨步跳技术进行分析。结果显示:踏跳着地技术的优劣表现在以髋关节为轴的大腿积极剪绞速度和幅度;踏跳缓冲技术中,形成以膝、踝关节主动缓冲的积极缓冲阶段和以屈踝缓冲为主的反射蹬伸阶段;踏跳蹬伸技术中,反射蹬伸阶段获得垂直速度,动力蹬伸阶段获得水平速度。The research method of measuring on SAFMS—T Six-dimension Force Platform combined with plane pinpoint video analysis was applied to analyzing the step technique of men's triple jumpers from the stages of impact, positive buffer, reflex driving leap, powerful driving leap etc. The results show that the merits and demerits of takeoff landing technique are embodied in the velocity and range of positive thighs scissors move which takes hip as an axis; takeoff buffer technique involves positive buffer stage formed with knee and ankle active buffer and reflex driving leap stage that takes knee-bending buffer as the dominant factor; and in the takeoff driving technique, the vertical velocity is obtained in the reflex driving stage, while the horizontal velocity is gained in the powerful driving stage.
