Structural and metabolic profile of rhesus monkey m. vastus lateralis after spaceflight.
The effect of microgravity on slow- and fast-twitch fibers of m. vastus lateralis of rhesus monkeys was investigated.  After real flight, fibers of both types were reduced in size, whereas after simulated flight, only type I fibers tended to diminish. Oxidative potential decreased in type II fibers of both flight and control animals.
