Abstract
Background: Chronic obstructive pulmonary disease (COPD) is a main risk for morbidity, associated with alterations in systemic inflammation. Recent studies proved that morbidity and mortality of COPD is related to systemic inflammation as it  contributes to the pathogenesis of atherosclerosis and cardiovascular disease. However, increase of inflammatory cytokines  adversely affects quality of life, alteration in ventilatory and skeletal muscles functions. Moreover, exercise training has many  beneficial effects in correction of the adverse effects of COPD.

Objective: This study aimed to compare the response of inflammatory cytokines of COPD to aerobic versus resisted exercises.

Materials and methods: One hundred COPD diseased patients participated in this study and were randomly included in two
groups; the first group received aerobic exercise, whereas the second group received resisted exercise training for 12 weeks.

Results:The mean values of TNF-α, Il-2, IL-4, IL-6 and CRP were significantly decreased in both groups. Also; there was a  significant difference between both groups at the end of the study with more reduction in patients who received aerobic exercise  training.

Conclusion: Aerobic exercise is more appropriate than resisted exercise training in modulating inflammatory cytokines level in  patients with chronic obstructive pulmonary disease.

Keywords: Aerobic exercise, chronic obstructive pulmonary disease, inflammatory cytokines, resisted exercises.
