    摘要:

    比较10周不同支撑方式的北欧腘绳肌运动对膝关节离心控制屈曲角度和离心肌力的影响。方法 选取28名高校男子足球运动员,随机分为手支撑组(HS组,n=14)和非手支撑组(NHS组,n=14),进行10周北欧腘绳肌训练,对干预前后的膝关节离心控制屈曲角度和离心肌力进行测试。结果 10周北欧腘绳肌运动后:1)HS组和NHS组膝关节离心控制屈曲角度分别显著减小8°和10°(均P < 0.05),且NHS组比HS组小12°(P < 0.05);2)HS组和NHS组的腘绳肌和股四头肌离心运动峰力矩均显著增加,且NHS组腘绳肌离心运动峰力矩在角速度60°/s和120°/s时分别比HS组高16N和13N(均P < 0.05)。结论 非手支撑方式在改善膝关节离心控制屈曲角度和离心肌力方面均优于手支撑方式。建议将非手支撑的北欧腘绳肌运动作为足球运动员日常训练之一,用于预防腘绳肌损伤。

    Abstract:

    Objective To compare the effects of different support methods on eccentric control angle and muscle strength of knee joint in 10 weeks Nordic hamstring exercise. Methods Twenty-eight college male football players were randomly divided into hand support group (HS group, n = 14) and no hand support group (NHS group, n = 14) for 10 weeks. The eccentric control angle and eccentric muscle strength of knee joint were tested before and after the intervention. Results After 10 weeks of Nordic hamstring training: 1) the eccentric control flexion angle of knee joint in HS group and NHS group was significantly decreased by 8° and 10° (both P < 0.05), and the knee joint in NHS group was 12° lower than that in HS group (P < 0.05); 2) the peak torque of hamstring and quadriceps femoris in both HS and NHS groups was significantly increased, and the peak torque of hamstring centrifugal motion at 60°/s and 120°/s in NHS group was 16N and 13N higher than that in HS group, respectively (all P < 0.05). Conclusions NHS group is better than HS group in improving knee flexion Angle and centrifugal muscle force. It is suggested that Nordic hamstring training should be taken as one of the daily training for football players to prevent hamstring injury.
