| Type | MGI:General | Description | EDL and soleus muscles are weak; EDL muscle fibers produce less force at 3, 6, and 9 months of age, EDL and soleus muscles produce less maximal specific force, and have right shifted force-stimulation frequency relationships, with differences seen at 10, 20, 40, and 60 Hz of stimulation, both EDL and soleus muscles have lower twitch-specific force production, and the maximum rate of rise of the twitch responses is 50% slower in muscles the twitch responses are slower relative to wild-type muscles |
