effects of aerobic exercise on NF-kappaB and TNF-alpha in lung tissue of male rat

ABSTRACT

Regular aerobic exercise improves the inflammatory status in different lung diseases. However, the effects of long-term aerobic exercise on the lung response have not been investigated. The present study evaluated the effect of aerobic exercise on the lung inflammatory. 12 adult male Wistar rats were divided to 2 groups A control [n=6], B aerobic exercise [five times per week for 4 week; n=6]. The gene expression of NF-kappaB and TNF-alpha were analyzed in lung tissue by Real time-PCR. In order to determine the significant differences between groups independent t-test were used. Aerobic exercise inhibited the gene expression of NF-kappaB and TNF-alpha. But there was no significant difference between A and B groups for TNF-alpha and NF-kappaB. We conclude that four week aerobic exercise decrease inflammatory status in lung tissue. Our results indicate a need for human studies that evaluate the lung responses to aerobic exercise
