Until the moment, no study explored conjunctively the physical activity relation, using the inflammatory biomarkers, with the periodontitis. This way, the objective of this experiment was to evaluate the muscular tissue behavior of rats submitted to physical exercise in aquatic environment with experimental disease. Twenty-four male Wistar rats were divided in 4 groups: 1) control and sedentary (CS); 2) control and active (CA); 3) with the periodontal disease and sedentary (PDS); with the periodontal disease and active (PDA). On the group that the periodontitis was induced, it was for ligature and the groups with active swimming activity have practiced it for 4 weeks. At the end of 30 days the animals were euthanized and a portion of the gingival tissue and the soleus muscle were removed and underwent analysis by ELISA and morphological and morphometrical analysis of the muscle. Data drawn from the analysis was analyzed through ANOVA and Tukey. Results have shown that there is a higher expression of TNF-α in the gingival tissue and on the muscular tissue of the rats that underwent the induced periodontitis independently of the physical activity (PDS and PDA), as a meaningful decrease on the conjunctive tissue on the groups with induced periodontitis, that have or have not undergone active swimming activity which could suggest a predisposition to muscular injury or difficulty of muscular recovering on these groups. Therefore, it was possible to highlight a correlation between the periodontal disease and the muscle morphological changes, and, moreover, the physical swimming activity promoting an acceleration of the regeneration of the muscle tissue (AU)
