采用形态学和组织化学方法研究了不同频率跑台运动对制动诱导的大鼠比目鱼肌和腓肠肌萎缩及踝关节挛缩的影响。大鼠右踝关节制动2周。随后，将大鼠随机分为4组，在不同条件下进行6周的运动：自由笼活动和自由再动员（FR），每周一次跑台跑步（低频跑步计划（LFR）），每周三次跑台跑步（中频跑步计划（MFR））和每周六次跑台跑步（高频跑步计划（HFR））组。制动2周后，I型比目鱼肌横截面积显著减小（62%，P
We investigated the effects of different frequencies of treadmill running on immobilization-induced soleus and gastrocnemius muscle atrophy and ankle joint contracture in rats using morphology and histochemistry. The right ankle joint of rat was immobilized for 2 weeks. Thereafter, the rats were randomly assigned to four groups for 6 weeks of exercise under different conditions: free cage activity and free remobilization (FR), once-a-week treadmill running (low-frequency running program (LFR)), three-time-a-week running (middle-frequency running program (MFR)), and six-time-a-week running (high-frequency running program (HFR)) groups. Two weeks of immobilization significantly reduced the cross-sectional area of soleus type I (62%, P
