Regular exercise training attenuates pulmonary inflammatory responses to inhaled alumina refinery dust in mice

► For the first time the interaction between exposure to alumina and exercise is addressed. ► In mice exposed to alumina the viscoelastic component of elastance and the viscoelastic/inhomogeneous pressure augmented. ► In the same animals the lung polymorphonuclear amount, the fraction area of alveolar collapse and TGF-β increased. ► Exercise may mitigate the pro-inflammatory response to inhaled aluminum refinery dust.
