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 knee flexion and extensor torque ratio (H / Q), the difference between the same name of the two legs and the influence of rehabilitation training on the knee injury of 60 athletes were studied. The use of Japanese-made GH221 advanced thigh muscle trainer, training 3 times a week for a total of 8 weeks, the results showed that: knee injury athletes knees knee H / Q values ​​will change, targeted rehabilitation training, H / Q values ​​range from 50-60%. Changes in knee H / Q values ​​can be used as an important indicator of rehabilitation training evaluation.
