The aim of this study is to investigate the effectiveness of eccentric exercise in the form of downhill walking (DW) on respiratory capacity, physical function and quality of life (QOL) in patients with COPD. Methods: The randomized controlled trial was carried out during 2014 - 2015 in Hazrat-e-Rasool Hospital in Tehran, Iran. The study design was as an assessor blind RCT on 32 patients with COPD that randomly assigned to the eccentric training (ET) and control (CON) groups. Patients in ET group received a 12-week DW exercise on the treadmill while the patients in the control group were only treated by COPD conventional medications and walked on paved surfaces. Functional tests, FEV1, FEV1 to FVC and St. George’s Respiratory Questionnaire (SGRQ) were used to assess the subject’s physical status and QOL pre and post-intervention. Results: The FEV1 (p=0.008), FEV1/FVC (p=0.002), six-minute walk test (p=0.029), timed up & go test (p=0.023), SGRQ symptom (p=0.022), SGRQ activity (p=0.007), SGRQ impact (p=0.033) and total score of SGRQ (p=0.013) improved significantly in the ET group compare to the CON group. Conclusion: DW could have positive influence on physical status and QOL of patients with COPD. LA eng UL http://mjiri.iums.ac.ir/article-1-4501-en.html M3 10.14196/mjiri.32.49 ER -
