Chest
Clinical Investigations: COPDThe Effects of 1 Year of Specific Inspiratory Muscle Training in Patients With COPD
Section snippets
Subjects
Forty-two consecutive patients, 32 men and 10 women, with spirometric evidence of significant chronic airflow limitation (FEV1< 50% of predicted, FEV1/FVC < 70% of predicted) with a diagnosis of COPD according to the criteria of the American Thoracic Society14 were recruited from the community. The patients were all new to an IMT program, and none were receiving additional regular exercise or dietary supplements. All were receiving regular long-acting bronchodilators, and 34 patients were
RESULTS
There were no significant differences between the two groups in age, height, weight, mean baseline FEV1and FVC, Pimax, 6MWT, and prior hospital admissions at the beginning of the study. Eleven patients dropped out of the study during the training period: 4 patients from the training group (2 of whom died) and 7 patients from the control group (4 of whom died). The attendance rate of the study was 63 ± 7% in the training group and 59 ± 8% in the control group (p = 0.082)
DISCUSSION
This study shows that in patients with significant COPD, long-term IMT results in an increase in the inspiratory muscle strength. This increase is associated with improved exercise performance, decrease in the sensation of dyspnea while breathing against resistance, improved quality of life, lower rate of primary care consultation, and fewer hospitalization days.
IMT has been extensively investigated in patients with COPD. More than a decade ago, Smith et al21 published the first meta-analysis

2022, Multiple Sclerosis and Related DisordersCitation Excerpt :Respiratory muscle training (RMT) is defined as an exercise that strengthens the respiratory muscles by adding a remarkable load on them (Silva et al., 2013). It may improve respiratory performance by a gradual increase in respiratory muscle strength (Valkenet et al., 2014; Beckerman et al., 2005). The mechanisms described for RMT function include strengthening the respiratory muscles and, consequently, increasing the volume of the lungs and more efficient secretion mobilization.
