Structural and metabolic characteristics of rhesus monkey m. soleus after spaceflight.
The effect of microgravity and diminished motor activity on m. soleus fibers of rhesus monkeys was investigated. A significant size reduction of both slow- and fast-twitch fibers was found in the flight animals only. Also, total protein and capillary per fiber number were shown to decrease in the flight animals.
