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:
