Introduction: uncertainty about the most effective way to muscles remobilization after periods of immobilization. Objective: to evaluate the behavior of swimming remobilization on histomorphometric soleus muscle parameters of ovariectomized rats. Methods: we used 24 Wistar rats divided into four groups: G1: underwent oophorectomy, immobilization for 15 days and remobilized freely; G2: oophorectomy, immobilization and remobilized with swimming for 10 days; G3: pseudo-oophorectomy, immobilization and remobilized freely; G4: pseudo-oophorectomy, immobilization and remobilized with swimming. The right and left soleus muscles were dissected for longitudinal and transverse histomorphometric analysis. The count of sarcomeres occurred at 300 mu m and muscle fiber length was measured by analog caliper. The muscle weight was obtained in an analytical scale and the diameter was performed on 100 fibers per muscle. Results: there was a significant reduction in both, the longitudinal and transversal analysis, when comparing the right with the left soleus muscles of all groups. Conclusion: the immobilization of the soleus muscle of ovariectomized rats and pseudo-ovariectomized cause deleterious effects on muscle morphology and remobilization through swimming was not able to promote the return of the structural patterns of the soleus muscle.
