| Research Abstract |
Recovery from skeletal muscle atrophy by resistance exercise was examined in mice. After tail suspention, the animals were subjected to resistance exercise(RE). The myofiber thickness of soleus muscle of the mice with RE was significantly greater than that of non RE group, and was not significantly different from normal mice. Intriguingly, the number of myonuclei of the mice with RE was 1.5 times greater than that of non RE mice. We found that the newly-acquired myonuclei were increased within a few days after the onset of RE, suggesting that satellite cells proliferated rapidly after the onset of RE and fused to the myofibers.
