[Effects of different types of exercise on contractile properties and expressions of MuRF1, PGC-1α /FNDC5 in soleus muscle of unloaded rats].

To investigate the effects of aerobic versus resistance exercise on soleus muscle contractile properties and the expressions of MuRF1, PGC-1α and FNDC5 in amyotrophic rats after unloading, and the possible molecular biological mechanisms. Male Wistar rats were randomly divided into recovery group (CT), aerobic exercise group (A), resistance exercise group (R) and control group (C), with 6 rats in each group. The control group did not receive any treatment.
