1、跆拳道高水平运动员后横踢技术动作肌力特征摘要：运用JE-TB0810八通道肌电采集测试系统和IS0ME：D2000等速测试训练系统，对两名国际健将级貽拳道运动员分别进行肌电和等速肌力测试，旨在确定跆拳道运动员后横踢技术动作的主要发力肌肉、肌肉用力持续时间、肌肉用力大小以及肌肉用力的协调性；其次是诊断影响后横踢技术动作的髋、膝关节在不同运动速度下肌力的屈伸比例、异侧同名肌群的肌力比例和肌肉功率特征。研究发现：在后横踢左脚前右脚后的实战动作技术中，主要发力肌肉是右股二头肌、左右侧臀大肌、右股直肌、左右股内侧肌、左股直肌、腓肠肌。在诊断分析影响后横踢技术动作时，需要考虑髋、膝关节屈伸肌力和做功功率的
2、平衡性，以及左右侧同名肌群肌力和功率的大小。关键词：运动生物力学；跆拳道运动员；后横踢；肌力特中图分类号：G886.9;G804.6文献标识码：A文章编号：1006-7116(2009)09—0110—03Characteristicsofmusclestrengthinthetechnicalmoveofbackwardcross-kickingmadebyhighperformancetaekwondoplayersHUANGBao-hong(SchoolofPhysicalEducation,AnhuiNormalUniversity,Wuhu241000,China)Abstract：
