There is an association between opioid addiction and dysfunction of various body organs, especially lungs. This study was aimed to determine the effect of sub-maximal aerobic training on pulmonary function tests in addicts. As a quasi–experimental with pre- and post-test designed study, 20 addicted male (20-33 years old) participated in. The participants were divided into exercise-drug supplement (n=10) and drug supplement (n=10) groups. In first group, the subjects consumed 10 milligrams Methadone daily and performed exercise training with 70-75 percent of VO2max as a sub-maximal intensity for twenty sessions. In second group, the participants only consumed 10 milligrams Methadone daily. By the end of study interventions, the pulmonary function indices in subjects were assessed. Finally, data analysis was performed by Stata software. The statistical analysis showed that the pulmonary function tests such as FEV1/FVC, FEV1, PEF, FEF25, FEF25-75, FEF50 and FEF75 were significantly increased in exercise-drug supplement group (p<0.05). In addition, the rate of FEV1/FVC were significantly increased in drug supplement group (p<0.05). Moreover, serum levels of CC16 were significantly decreased in exercise-drug supplement group (P=0.029, t9=2.591). The study results showed that in comparison to only drug supplement, the drug plus exercise supplement is more appropriate for the improvement of pulmonary function in addict subjects. However, further researches are need to confirm the results.
