  Skeletal muscle atrophy can occur due to degenerative processes originating within the skeletal muscle fibers, secondary to denervation (denervation atrophy), or spontaneously in aging rodents. It is a common reaction to any injury that results in the degradation and/or loss of myofiber organelles.

  Even though muscle mass and strength can be regained once astronauts have returned to Earth, maintaining muscle in space is a concern, especially for long-duration space missions. The only way to minimize muscle atrophy in space is through intensive exercise, particularly strength training exercises, combined with an adequate diet.
