BackgroundPulmonary fibrosis (PF) is easily caused by a variety of factors, resulting in dyspnea, exertion and movement intolerance. This systematic review aims to synthesize evidence on exercise training during rehabilitation for PF in order to improve patients' exercise capacity, quality of life, and lung function.MethodsRetrieved from the Cochrane Library, Web of Science, PubMed, Scopus and Embase from inception until April 2022. Participants: patients with PF; Intervention measures: exercise training; Results: exercise ability, quality of life, lung function and cardiopulmonary endurance. Two reviewers independently screen the title, abstract and full text. Finally, quality evaluation and meta-analysis were conducted.ResultsIn this study, 13 randomized controlled studies from 1468 articles were selected. A total of 456 patients with PF were enrolled. Compared with usual care in the control group, the 6-minute walking distance, predicted forced vital capacity, predicted forced expiratory volume at 1 second and maximal rate of oxygen consumption were increased significantly after exercise training, while there was no significant change in quality of life and predicted diffusing capacity of the lung for carbon monoxide.ConclusionExercise training can significantly improve the exercise capacity, lung function and cardiopulmonary endurance of patients with PF, but has no effect on the quality of life. Exercise training is an effective rehabilitation strategy for PF.Copyright © 2022 the Author(s). Published by Wolters Kluwer Health, Inc.
