[Subjects and Methods] Thirty 8-week-old male Wistar rats were divided into 4 experimental groups: control, hind-limb suspension (H), hind-limb suspension and stretching for 10 minutes every day (LST), and hind-limb suspension and stretching for 5 minutes every day (SST). At the end of the suspension period, the soleus muscle was excised and cut into proximal, middle, and distal samples, and the cross-sectional area (CSA) was measured. [Results] The cross-sectional area of muscle fibers was significantly higher in the LST and SST groups than in the H group in the middle and distal regions, and it was also higher in the SST group than in the LST group in the distal region. [Conclusion] These results suggest that the effect of intermittent stretching differs among the longitudinal sites of the rat soleus muscle, and depends on the duration of the stretching time., 出版者照会後に全文公開},
