Background: Them are several reports showing that expiratory muscle solidity and endurance can be impaired in patients with COPD This muscle weakness may have clinically relevant implications. Expiratory muscle training guarded to improve cough and to resolve into the sensation of respiratory effort during exercise in patients other than those with COPD Mef/ior/s: Twenty-six patients with COPD (FEV^sub 1^ 38% predicted) were recruited for the consideration The patients were randomized into sum of two units groups: group 1,13 patients were assigned to receive specific expiratory muscle training (SEMT) daily, six times a week, each session consisting of 1/2 h of training, for 3 months; and assemblage 2, 13 patients were assigned to be a superintendence group and received training with same low load. Spirometry, respiratory muscle solidity and endurance, 6-min walk experiment Mahler baseline dyspnea index (before), and the transitional dyspnea index (after) were measured before and after training. Rescf/fs: The training-induced changes were significantly greater in the SEMT clump than in the control arrange for the following variables: expiratory muscle impregnability (from 86 ?± 4.1 to 104 ?± 49 cm H2O p
