| 摘 要： | 运用等速测试系统对备战伦敦奥运会的国家划艇运动员的肩关节、肘关节肌力进行测试与分析。结果表明:1)从力矩角度来看,优秀运动员与一般运动员在肩、肘关节肌力特征中存在显著性差异(P<0.05),且屈肌和伸肌的力矩角度分别呈现不同的特征;2)从峰力矩比值来看,在不同速度运动下,国家队优秀运动员和一般运动员均存在屈伸比的失衡问题,即最大力量上存在屈伸肌群发展的不合理化现象(<50%),随着测试速度的增加,屈伸比呈递减趋势;3)在肘关节两侧同名肌群的比较中同样存在不均衡现象,尤其是伸肌的两侧差值较大;4)肩关节的肌力特征也存在类似的现象,但屈肌明显不如伸肌力量。结论:应逐步加强划艇运动员肩、肘关节同侧屈伸肌群和异侧同名肌群的力量均衡性训练,并提高肩关节的屈肌力量能力。

| Abstract: | Based on the isokinetic testing,this article measured and analyzed the muscle strength feature of elbow and shoulder of elite canoe athletes preparing for the 2012 Olympic Games.The results showed that 1) as far as torque angle is concerned,there are some significant difference between different athletes for elbow and shoulder(P<0.05),and the flexor and extensor torque angle are respectively different;2) the ratio of peak torque is imbalance under different speed movement,that is to say,the maximum force is unreasonable in flexor and extensor,with the increasing of testing velocity;3) the comparison of same muscle group shows the imbalance phenomenon,especially the extensor muscle;4) shoulder joint muscle strength exists a similar phenomenon,but flexor muscle is more worse than extrensor strength.It has been concluded that it should strength the balance training of the flexor and extensor muscles and metachronous contralateral homonymous muscles for shoulder and elbow,meanwhile,to improve the flexor muscle strenght of shoulder. |
