Evaluation of the efficacy of inspiratory muscle training in older adults with DPOC

By Azevedo MC, dos Santos NP

Chronic obstructive pulmonary disease (DPOC) is a respiratory condition that progresses over time, characterized by persistent airflow limitation, chronic inflammation, and functional impairment. This disease particularly affects older adults because of the natural changes that occur with aging. Among the main effects of DPOC in this age group, we can highlight respiratory muscle weakness, which is associated with shortness of breath, difficulty performing activities, and a decline in quality of life. In this context, inspiratory muscle training (TMI) has been widely studied as a nonpharmacological approach in pulmonary rehabilitation. The objective of this study was to analyze the efficacy of TMI in respiratory muscle strength, functional capacity, and quality of life in older adults with DPOC through an integrative review of the scientific literature. This review is descriptive and qualitative, based on a search for articles published between 2016 and 2026 in the PubMed and Google Scholar databases. After applying the inclusion and exclusion criteria, 11 studies were selected for analysis. The results showed that TMI leads to a significant increase in maximal inspiratory pressure, improved functional capacity, and reduced shortness of breath in older adults with DPOC. Furthermore, when combined with pulmonary rehabilitation, TMI provided additional benefits for functional performance and well-being. In conclusion, inspiratory muscle training proves to be a safe, effective, and low-cost intervention, representing an important strategy in the physical therapy treatment of older adults with DPOC.
