摘要
目的:探讨优秀女子武术运动员膝关节肌肉力量的特点。方法:采用等速肌力测试方法,对四名优秀女子武术运动员左、右膝关节进行慢速60°/S和快速240°/S的屈、伸进行定量测试。结果:在60°/S和240°/S测试中,四名运动员屈肌群变化不大,而伸肌群下降较多。相比60°/S测试,在膝关节快速屈伸过程中,膝关节最佳用力角度出现的更早。结论:戴和刘膝关节力量发展较好,屈、伸肌力量和两侧关节同名肌力量发展较均衡,呈现出专项特点。而周的异侧同名肌群比差异大于10%,需加强右侧膝关节股前肌群的锻炼,宋的左膝关节屈肌群需要加强爆发力的练习。
The purpose of the paper is to explore the characteristics of knee joint muscle strength of outstanding fe- male wushu athletes. Isokinetic muscle strength testing method is used to conduct a quantitative test on four outstanding female wushu athletes＇ left and right knees for their slow 60°/s and 240°/s bending and stretching. The results show that the four subjects exhibit little change in their flexor group, but a relatively more decrease in their extensor group. Compared with 60°/s test, the best powering angle of the knee joint appears earlier in the process of fast flexion and ex- tension. The paper draws the conclusion that two of the subjects develop better in their knee joint strength with balanced flexion and extension muscle strength and special characteristics. Another subject shows a bigger different muscle group rate on the opposite side of the same name than 10%, so he needs to strengthen the anterior muscle group of right knee joint, and the last one needs to exercise the explosive power of his left knee joint flexor muscles.
