摘　　要：通过对34名大学生双侧膝关节进行的等速测试,本文对膝关节肌群等速向心收缩的力学特征进行分析,以峰力矩为度量指标,研究峰力矩与哪些因素有关,以及其关系的强弱。本文使用数学软件MTLAB进行统计分析计算,结果显示,峰力矩值与性别、体重、屈伸运动有关,峰力矩值在不同运动速度下具有显著差异且与运动速度负相关,峰力矩角度在不同运动速度下的值无显著差异。Through the isokinetic muscle testing of 34 college students ＇bilateral knee,isokinetic contract mechanical features in knee muscles are studied.The peak torque is chosen as a measurement index to study the related factors of it and the relationship between them.Using MATLB for statistical analysis,the results shows that the peak torque is related to gender,weight,and flexion and extension movement.The peak torque has significant negative correlation with different velocities.However,angle of peak torque has no significant difference with different velocities.
