Popis: A growing number of studies have shown that obesity induces airway hyperresponsiveness (AHR). AHR is a hallmark of asthma and several studies show a relation between obesity and development of asthmatic phenotype. Moderate intensity aerobic training (AT) inhibits asthma phenotype in experimental models of asthma, but the effects of AT on pulmonary response in a model of diet-induced obesity are unknown. Thus, 80 C57Bl/6 male mice were distributed in Control Lean (CL), Exercise Lean (EL), Obese (O) and Obese+Exercise (OE) groups (n=20). Obesity was induced by a classical model of diet-induced obesity (DIO) using high fat and hypercaloric diet. Treadmill aerobic training was performed for 4 weeks after the establishment of obesity and DIO remained during the whole protocol. The results demonstrated that AT reduced DIO-induced AHR for 25mg/mL (p
