O treinamento físico (TF) melhora a resposta imune de indivíduos saudáveis e traz benefícios para o paciente asmático, mas seu papel na resposta alérgica é desconhecido. Objetivo: Avaliar o papel do TF de moderada intensidade na inflamação pulmonar alérgica crônica. Métodos: 54 cobaias, divididas em 4 grupos: grupo controle (C) (não sensibilizados e não treinados), grupo OVA (sensibilizados à ovalbumina (OVA) e não treinados), grupo treinamento físico (TF) (não sensibilizados e submetidos a um TF), e grupo OVA+TF (sensibilizados à OVA e submetidos a um TF). A sensibilização à OVA teve duração de 8 semanas e o programa de TF de 6 semanas iniciando 15 dias após o início da sensibilização. Cada grupo foi dividido em 2 subgrupos. No primeiro foi avaliada a inflamação pulmonar e os níveis de óxido nítrico exalado (NOex) e no segundo, a hiperresponsividade brônquica à metacolina (Mch). Resultados: A sensibilização à OVA induziu a um aumento da densidade de eosinófilos e linfócitos, expressão de IL(interleucina)-4 e IL-13 e na espessura do músculo liso na via aerea assim como espessura do epitélio comparado aos animais não-sensibilizados (p<0,05). Os animais do grupo OVA+TF apresentaram uma redução da densidade de eosinófilos, linfócitos, IL-4 e IL-13 comparado com o grupo OVA (p<0,05). Nem a sensibilização crônica a OVA ou TF influenciaram a expressão das citocinas Th1 (IL-2 e IFN-) ou a expressão das citocinas regulatórias (IL-10 e IL-1-ra) e nos níveis de NOex. Os grupos que realizaram TF tiveram aumento na espessura do epitélio quando comparados com grupos não-treinados embora não há diferença entre os grupos na avaliação da hiperresponsividade brônquica. Conclusão: Nossos resultados sugerem que o TF reduz a inflamação alérgica sem modificar a hiperresponsividade brônquica e o remodelamento das vias aéreas / Background: Aerobic training (TF) has a positive effects on health subjects and bring benefits on the immune system of asthmatic patients. However, its role on allergic immune response remains poorly understood. Objective: To evaluate the effects of TF in chronic allergic inflammation. Methods: Fiftyfour animals, divided in 4 groups: non-trained and non-sensitized (C), nonsensitized and aerobic exercise (TF), ovalbumin sensitized and non-trained (OVA), and sensitized and aerobic exercise (OVA+TF). OVA or saline sensitization was performed during 8 weeks. TF was performed in a treadmill during 6 weeks beginning in the 3rd week of sensitization. Each group were divided in two groups. In the first one, it was evaluated airway inflammation and levels of exhaleted oxide nitric (NOex), on the second, airway hyperresponsiveness to a methacholine (Mch). Results: OVA sensitization induced an increase in the eosinophils and lymphocytes counting, expression of IL-4 and IL-13 and the amount of airway smooth muscle and epithelium thickness compared to non-sensitized animals (p<0.05). Sensitized animals submitted to TF presented a reduction in the eosinophil and lymphocyte counting, expression of IL-4 and IL-13 compared with OVA group (p<0.05) but not OVA-induced changes in airway remodeling (p>0.05). Neither OVA nor TF induced any difference in the expression of Th1 (IL-2 and IFN-) and regulatory cytokine (IL-10 and IL1-ra) and the levels of NOex. Trained groups presented an increase in epithelium thickness as compared to the nontrained groups however we did not find difference between groups on hyperresponsiveness avaliation. Conclusion: Our results suggest that TF reduces allergic airway inflammation without changes in bronchial hyperresponsiveness and airway remodeling
