陕西省优秀跆拳道运动员膝关节等速测试的力学分析

摘要

采用ISOMED2000对陕西省优秀跆拳道运动员进行膝关节等速测试,获得屈伸肌群向心收缩的生物力学参数。结果表明：跆拳道运动员右膝的力量与爆发力强于左膝,建议加强左膝屈伸肌群的力量练习与训练中的实战进攻训练;左右膝关节屈伸肌群力量比值不合理,建议加强屈肌群的力量训练;建议以300o/s屈小腿,可以快速有效的回防并为下次进攻做好准备,建议以300o/s伸小腿,可以发挥小腿伸肌群的爆发能力。%This study adopts isomed2000 system to get the biomechanical characteristics of excellent TKD athletes＇knee muscle group.The right knee strength and explosive strength are bigger than the left knee＇strength, suggesting strengthen the left knee f muscle strength and the attack training exercises; In order to effectively to shorten the action time, We suggest benting the calf at the speed of 300°/s; In order to effectively show the outbreak of the leg, We suggesting extent the calf at the speed of 300°/s.
