对膝关节损伤运动员屈、伸肌力矩比值的研究

A STUDY OF THE HAMSTRING/QUADRICEPS PEAK TORQUE RATI0

研究了60例膝关节损伤运动员的屈、伸肌力矩比值(H/Q值)、两腿同名肌力矩相差值及康复训练对这些值的影响。运用日本产GH221高级型大腿肌肉训练器,每周训练3次,共8周,结果发现:膝关节损伤运动员患膝的H/Q值也会发生改变,进行有针对性的康复训练,可使H/Q值向50—60%范围发展。患膝H/Q值变化可作为康复训练效果评定的重要指标。

The purpose of this study was to investigate the hamstring/quadriceps peak torque ratio(H/Q), the differences of the quadriceps and the hamstring peak torques (PT) betweenbilateral muscle groups in athletes with the knee joint injuries, and the effects of rehabili-tation training on these values. Sixty male athletes with various knee joint disorders (chon-dromalacia of patella, meniscus injuries, ligamentous injuries) were studied. All the subjectswere trained in progressive resistance rehabilitation exercise, which included 3 times perweek for 7 weeks. The results showed that significant increases in PT of the quadriceps and hamstrings inthe injured knee joint were found after rehabilitation training. The suitable range of theH/Q in Chinese athletes was 50-60%. H/Q ratio trended toward suitable range in athleteswith the knee joint injuries after trainig. The normal value of the differences of PT betweenbilateral muscle groups was under 10% in Chinese athletes, and the value in athletes withthe knee joint injuries tended to the normal value after training.
