【摘要】：采用德国IsoMed 2000等速肌力测试仪,对17名健将(健将组)和18名一级(一级组)男子举重运动员进行双侧髋、膝和踝关节60°/s、120°/s、180°/s和240°/s向心、离心(每种角速度5次)测试。探讨优秀男子举重运动员下肢关节不同角速度等速肌力的特征,比较健将与一级组间差异,对健将组下肢关节相对峰力矩与相对专项成绩进行Pearson相关分析,并建立抓、挺举与峰力矩多元线性回归方程。结果显示,优秀男子举重运动员的髋关节相对伸爆发力与相对抓举呈高度显著正相关,髋关节中速(120°/s)、膝踝关节相对伸爆发力与相对抓举呈中度显著正相关,而踝关节相对屈绝对力呈中度显著负相关;髋关节相对伸爆发力与相对挺举呈高度显著正相关,左膝(挺举弓步腿)相对中速(120°/s)、爆发力和踝关节相对爆发力与相对挺举呈中度显著正相关。
[Abstract]:Using German IsoMed 2000 isokinetic muscle strength tester, 17 male weightlifters (healthy group) and 18 male weightlifters (level 1) were tested for bilateral hip, knee and ankle joint 60 掳/ s, 180 掳/ s and 240 掳/ s concentric centrifugation (5 times per angular velocity). The bilateral hip, knee and ankle joint 60 掳/ s, 120 掳/ s, 180 掳/ s and 240 掳/ s concentric, centrifugation (5 times per angular velocity) were used to test the bilateral hip, knee and ankle joint 60 掳/ s. To explore the characteristics of isokinetic muscle strength of lower extremity joint of elite male weightlifters with different angular velocity, compare the difference between the general group and the first class group, analyze the correlation between the relative peak torque and the relative special score of the lower extremity joint in the elite male weightlifter group, and establish the multivariate linear regression equation of grasping, lifting and peak torque. The results showed that the relative explosive force of hip joint of elite male weightlifters was highly positively correlated with the relative snatch, and the relative explosive force of knee and ankle joint was positively correlated with the relative snatch, while the relative flexion force of ankle joint was negatively correlated with the relative snatch of the middle speed of hip joint (120 掳/ s),). The relative explosive force of hip joint was positively correlated with the relative clean and jerk, and the relative moderate velocity (120 掳/ s), explosive force of left knee) and the relative explosive force of ankle joint were positively correlated with the relative clean and jerk.
