摘要
目的:探讨优秀男子举重运动员腰背和膝关节等速肌力特征,分析与抓、挺举成绩的相关性。方法:采用IsoMed 2000等速测试仪,对12名受试者的腰背和膝关节进行等速肌力测试。结果:分析了不同角速度测试下的相对峰力矩、拮抗肌与主动肌之比、异侧同名肌比等指标。腰背、膝关节相对峰力矩与受试者抓举/体重、挺举/体重的相关性。结论:(1)受试者腰背屈伸比范围在0.27-0.50,膝关节屈伸比范围在0.41-0.73。多数受试者膝关节异侧同名肌差异在20%以内,但在快速测试中有3名运动员需要加强弱侧肌群的锻炼。(2)抓举/体重与腰背快速伸和膝关节中速屈、膝关节快速伸相对峰力矩值均呈中度显著正相关;挺举/体重与腰背快速伸相对峰力矩值呈中度显著正相关,与膝关节慢速伸相对峰力矩值呈中度显著正相关。建议加强运动员腰背后伸的爆发力、膝关节伸的绝对力量和爆发力练习。
Objective ： The purpose of this paper is to investigate the characteristics of elite male weightlifters＇ trunk and knee isokinetic muscle strength, and analyze their correlation with snatch and clean and jerk performance. Method： IsoMed 2000 is used to conduct isokinetic muscle strength test on12 subjects trunk and knee joint. Results： The indexes of the relative peak torque, untagonist muscle, the ratio of the active muscles and the ratio of side muscle with the same name are analyzed. The correlation between the relative peak torque of the trunk and knee and the subjects＇ snatch / weight, lean and jerk weight/weight are also analyzed Conclusion ： （ 1 ） The subjects F/E ranges from 0.27 to 0.50, H/ Q （0.41 -0.73 ）, with the difference of most subjects＇ side muscle of knee with the same name being within 20%, but in the quick test, 3 players need to strengthen the weaken side muscle group. 2） Snatch/weight demonstrates moderate positive correlation significantly with back extensor and knee medium - speed flexor, knee joint extensor＇ s relative peak torque values. The clean and jerk/weight and the relative peak torque value of jerk trunk extensor have significantly moderate positive correlation with the relative peak torque values of the knee extensor. It is suggested that athletes should strengthen their explosive force of trunk extensor and their absolute strength and explosive powering the knee joint extensor.
