目的：通过对湖南师范大学9名北狮运动员双侧膝关节屈伸肌群进行等速测试，为揭示该项运动膝关节肌群收缩的生物力学特性提供实验依据。方法：采用BIODEX SYSTEM3等速测试系统对湖南师范大学北狮运动员膝关节屈伸肌群进行等速测试，测试指标为峰力矩、相对峰力矩、屈伸肌峰力矩比、平均功率及做功疲劳度。结果：1）北狮运动员双侧膝关节屈伸肌峰力矩和相对峰力矩随测试速度的增加呈递减趋势；2）狮头狮尾屈伸肌群峰力矩比值和做功疲劳度无显著性差异；3）狮头狮尾左右膝关节同一肌群峰力矩无显著性差异。结论：舞狮运动员膝关节肌群峰力矩变化随测试速度的增加而减少，平均功率呈现随运动速度的增加而增加。到达一定速度后随速度的增加而减少的特征。

Objective： In order to reveal the characteristics of knee joint＇ s muscle contraction in lion dancing player and provide experimental basis for Scientific training, we explored nine lion dancing players＇ bilateral knee joint in Hunan Normal University by isokinetie machine. Method： The isokinetie explortion was carried out in lion dancing player＇ S knee joint＇ s flexion and extension muscle groups in Hunan Normal university with BIODEX SYSTEM 3. The explortion index are peak torque, peak torque to body weight, flexion and extension peak torque ratio, average power and work fatigue. Result： I } the peak torque and relative peak torque of the lion dancing player＇ s bilateral knee flexion and extension muscles increase with the explortion speed; 2 } there was no signifi- cant difference in average power and in working fatigue between lion head and lion -tail＇ s knee joints. 3 } there was no significant difference in the same muscle＇ s strength of lion head or lion tailed between left and right knee joints . Conclusion ： Lion athletes knee muscle peak torque changes in the rate of increase with the reduction of ve- locity in testing, Changes of average power increases with velocity up to a certain speed and then decrease. Key words： Lion Dance; Knee Joint; Isokinetie Muscle Strength; Coneeutrie Contraction.
