| 中文摘要: |
| 运用CYBEX－Norm型等速肌力测试与康复系统，以上海市优秀田径运动员为研究对象，探讨腘绳肌拉伤后的等速参数变化，分析伤后的恢复情况。结果显示：受伤运动员伤侧腘绳肌峰力矩角度明显增大，表明拉伤腘绳肌达到最大力量的时间明显延长，最大收缩长度发生了改变。建议：在运动实践中，合理运用等速测试的峰力矩角指标作为腘绳肌拉伤后恢复效果的监控指标，并结合适当比例的离心训练，将有助于减少运动中腘绳肌的拉伤。 |
| 英文摘要: |
| Using CYBEX-Norm isokinetic muscle strength test and rehabilitation system and taking the elite athletes of Shanghai as the subjects, the author tries to uncover the changes of isokinetic parameters after the injury of hamstring and evaluate the rehabilitation. The result shows that the peak torque angle of the injured hamstring increases obviously. This proves that the time for the injured hamstring to reach the maximum strength extends apparently and the maximum contract length changes. The paper suggests that the peak torque angle indexes be used appropriately as the indicators for monitoring the rehabilitation effects after the injury of hamstring. And centrifugal training of rational proportion will help reduce the injury of hamstring in exercise. |
