ABSTRACT This systematic review aimed to demonstrate the effectiveness of inspiratory muscle training (IMT) in people with chronic obstructive pulmonary disease (COPD), analyzing effects IMT on strength and endurance, exercise tolerance reduction dyspnea. A search was carried out PubMed, Cochrane Lilacs databases, from August 2021 February 2023, searching for studies published 2016. The descriptors used followed description MeSH/DeCS terms, namely: “Pulmonary Disease, Chronic Obstructive,” “Breathing Exercises,” “Exercise Tolerance,” “Dyspnea,” “Muscle strength,” languages: English Portuguese, using Boolean operators “AND” “OR.” Ten met inclusion criteria, including 733 patients. In all examined studies, there a significant increase endurance compared control group; ten analyzed, four showed advances reducing dyspnea tolerance. Notably, is effective improving dyspnea, tolerance, increasing moderate severe COPD.
