| 摘 要： | 通过对两名高水平女子链球运动员双侧的髋关节和膝关节进行等速测试,探究运动员髋关节和膝关节周围肌群的生物力学特性,为运动训练和运动康复等提供理论依据。利用等速肌力测试系统对两名运动员的髋关节和膝关节屈伸肌群以及髋关节的旋内旋外肌群进行等速测试。结果发现:两名运动员双侧髋关节和膝关节屈伸肌群以及髋关节的旋内旋外肌群的峰力矩随测试速度的增加呈递减趋势,髋膝关节峰力矩屈伸比和髋关节旋内旋外比随既定测试速度的增加呈递增趋势;同一测试速度下,伸肌肌群的峰力矩大于屈肌肌群,髋关节旋外肌群的峰力矩大于旋内肌群。

| Abstract: | By running an isokinetic test on the hip joints and knee joints at both sides of two high performance fe-male hammer athletes,the authors probed into the biomechanical characteristics of muscles surrounding the hip joints and knee joints of the athletes,so as to provide a theoretical criterion for sports training and sports rehabilita-tion.By utilizing an isokinetic muscle strength testing system,the authors ran an isokinetic test on the flexors and extensors of the hip joints and knee joints as well as the intortors and extortors of the hip joints of the two athletes,and revealed the following findings: the peak moments of the flexors and extensors of the hip joints and knee joints at both sides as well as the intortors and extortors of the hip joints of the two athletes showed a trend of decreasing with the increase of the test speed;the ratio of flexion peak moment to extension peak moment of the hip joints and knee joints and the ratio of intorsion to extorsion of the hip joints showed a trend of increasing with the increase of the set test speed;at the same test speed,the peak moment of extensors was greater than the peak moment of flex-ors,while the peak moment of extortors of hip joints was greater than the peak moment of intortors. |
