From end of paper: "The fact that MHC I fibers from the vastus lateralis [previously reported research] and soleus muscle atrophy to a similar extent with long duration unloading, but respond differently to the same exercise loading program was an interesting and novel finding. These data suggest that unique and specific exercise regimens for the upper (vastus lateralis) and lower leg (soleus) may be necessary to protect human skeletal muscle during extended unloading periods."
