Background: Respiratory muscle weakness may contribute to dyspnea and exercise limitation in patients with significant COPD In an attempt to abridge the severity of breathlessness and to improve exercise tolerance, inspiratory muscle training has been applied in many COPD patients. forward the other hand, there is a paucity of data related to expiratory muscle performance and training in COPD Methods: Thirty-two patients with significant COPD (ie, mean FEV^sub 1^ 37% of predicted) were recruited for the application of mind The patients were randomized into four groups: eight patients were assigned to receive specific expiratory muscle training (SEMT); eight patients received specific inspiratory muscle training (SlMT); eight patients received SEMT and SIMT (ie, the SEMT + SIMT group); and eight patients who were assigned to a bridle group received training with extremely low load. All patients trained daily, six times a week, with each session consisting of single half hour of training, for 3 month Spirometry, respiratory muscle potency and endurance, 6-min walk criterion distance, the perception of dyspnea, and the Mahler baseline dyspnea index (BDI) were measured before and following training. Results: Training caused a statistically significant specific increase in the expiratory muscle might and endurance (in the SEMT and SEMT + SIMT groups) and in the inspiratory muscle solidity and endurance (in the SIMT and SEMT + SIMT groups) There was significant increase in the distance walked in 6 min in the SEMT SIMT, and SEMT + SIMT collections However, the increase in the SIMT and SEMT + SIMT form into groupss was significantly greater than that in the SEMT dispose There was a statistically significant increase in the BDl and a decrease in the mean Borg score during breathing against resistance in the SlMT and SEMT + SIMT assemblages with no changes in the SEMT and hinder groups. Conclusions: The inspiratory and expiratory muscles can be specifically trained with improvement of as well-as; not only-but also; not only-but; not alone-but muscle strength and endurance. The improvement in the inspiratory muscle performance is associated with an increase in the 6-min walk touchstone distance and the sensation of dyspnea. There is no additional benefit gained according to combining SIMT with SEMT, compared to using SIMT alone.
