赵明,男,1963年11月出生,身高1.77米。从1980年开始进行有系统的标枪训练4年,成绩从45米提高到84.38米,成为我国第三个突破80米大关的运动员。本文试图对其投枪最后用力技术进行运动生物力学分析,希望能揭示其运动技术特点。一、研究方法用Photo-Sonic16mm摄影机以100格/秒速度从侧面(运动员投掷右侧)拍摄其投枪的动作。用BR-2三维测力台与微机相连记录最后用力时左脚三维支撑反作用力变化情况及现场处理打印出有关力学数据。在JJT-23J台式投影仪上读出照片中有关关节点的数据。所有数据均在SHAPR-731微机上进行处理。动力测试在本院田径场上进行。研究分两个阶段,
Zhao Ming, male, born in November 1963, 1.77 meters tall. Since 1980, systematic javelin training has been carried out for four years, increasing the score from 45 meters to 84.38 meters and becoming the third player to break the 80-meter mark in our country. This article tries to analyze the kinematic biomechanics of the final force technology of its shooting, hoping to reveal the characteristics of its movement technology. First, the research methods with Photo-Sonic16mm camera at 100 grid / second speed from the side (the athlete throwing the right) to shoot the shooting action. BR-2 three-dimensional load cell connected to the computer records the last force left three-dimensional support reaction force changes and field processing to print out the mechanical data. Read data about the knuckles in the photo on the JJT-23J desktop projector. All data is processed on the SHAPR-731 microcomputer. Power test in our hospital track and field. The research is divided into two stages,
