The influence of magnetic stimulation on muscle atrophy and changes in the composition of skeletal muscle fibers were examined in the rat soleus and plantaris muscles. Rats were divided into control (CON), hindlimb unloading (HU), and hindlimb unloading with magnetic stimulation (HUM) groups. Magnetic stimulation (20 s/time, 20 min) was applied to the posterior aspect of the lower thigh for 13 days. The means of the absolute and relative weights and cross-sectional areas of the soleus and plantaris muscles were not significantly different between the HU and HUM groups. The composition of muscle fiber types of the plantaris muscle in the HUM group were not significantly different from those in the HU group, but the values of type I fiber of the soleus muscle was significantly higher in the HUM group than in the HU group. These results indicate that while magnetic stimulation was unable to reduce muscle atrophy induced by hindlimb unloading, it reduced the changes in the properties of the muscle fibers, which suggests that the mechanism to induce muscle atrophy and to control the composition of skeletal muscle fibers may be different.
