| （安徽师范大学 体育学院，安徽 芜湖 241000） 摘 要：运用JE-TB0810八通道肌电采集测试系统和ISOMED2000等速测试训练系统，对两名国际健将级跆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平衡性，以及左右侧同名肌群肌力和功率的大小。 |

Via his study the author revealed that in real competitions, for the technical move of backward cross-kicking in which the left foot steps forward while the right foot steps backward, the major strength exploding muscles are the biceps muscle of the right thigh, the gluteus maximus of the left and right buttocks, the rectus muscle of the right thigh, the inner muscle of the left and right thigh, the rectus muscle of the left thigh, and the gastrocnemius muscle. When diagnosing and analyz-ing factors that affect the technical move of backward cross-kicking, the researcher should consider the balance be-tween the active power and the flexion and extension muscle strength of the hips and knee joints, as well as the magnitude of muscle strength and power of the same muscle group at the left and right sides. |
