摘要: Purpose: Persistent quadriceps weakness due to arthrogenic muscle inhibition (AMI) has been reported after anterior cruciate ligament (ACL) reconstruction. Fatiguing exercise shown alter lower extremity function and gait mechanics, which may be related injury risk. The effects of on in the presence AMI are not currently understood. purpose this study was compare effect 30 min soleus motoneuron-pool excitability ACL-reconstructed participants healthy controls. Methods: Twenty-six (13 women, 13 men) 26 recreationally active volunteers were recruited for a case-control laboratory study. All completed continuous including alternating cycles inclined-treadmill walking bouts squats step-ups. Knee-extension torque, central activation ratio (CAR), H:M ratio, V:M ra...
