- Abstract
Objective: to evaluate morphologically the tibialis anterior muscle of rats submitted to axonotmosis and treated with exercise. Methods: 28 Wistar rats were used in groups control (CG), exercise (GE), injury (GL) and injury + exercise (GLE). On the third day after compression, GE and GLE performed climb exercise staircase, with two sets of ten repetitions. After 21 days, the muscle was processed for light microscopy. Results: In the morphological analysis GC presented with morphology characteristic appearance, GE muscle hypertrophy, GL morphological changes like polymorphic fibers and central nucleo, and GLE look similar to the control, but with some changes morphological. In the cross-sectional area and smaller diameter of the GC and GE fiber showed higher values, inversed analysis of blood vessels. For the connective tissue, GE was lower than the GL. Conclusion: Summing up, the exercise promoted improvement in morphological aspects, but not totally reversed the deleterious effects of denervation.
