Exercise training prevented endothelium dysfunction from particulate matter instillation in Wistar rats.

Exposure to fine particulate matter (PM) can result in adverse cardiovascular responses including vascular endothelial dysfunction, whereas exercise training can promote cardiovascular health. However, whether exercise training can mitigate adverse vascular response to PM has been less studied. In the present study, we aimed to investigate the preventive effect of exercise training on vascular endothelial dysfunction induced by PM instillation.
