Background: The purpose of this study was to determine the effect of pretreatment of aerobic training on stress and inflammatory indices [heat shock protein-70 (HSP70), superoxide dismutase (SOD), malondialdehyde (MDA) and C-reactive protein (CRP)] induced by doxorubicin in lung tissue of aging male rats.Methods: 16 male rats were randomly divided into aging + doxorubicin (AD) and aging + doxorubicin + training (ADT) groups. The training group ran on a treadmill for three weeks at speeds of 15-17 m/minute for 25-39 minutes and five sessions a week. Subjects received doxorubicin (20 mg/kg) 24 hours after the last training session. The biopsy was taken 48 hours later. Data were analyzed using one-way ANOVA and Scheffe post hoc test via SPSS software.Findings: Three weeks of the aerobic training only resulted in a significant increase of HSP70 and SOD, and decrease of MDA in the lung tissue in the training group compared to the control group.Conclusion: Doing exercises before treatment with doxorubicin appear to be effective in elderly people, probably due to changes in the protective proteins of the cell in inhibiting or reducing oxidative damage.
