To investigate the effects of a stretching program for the muscles of the rib cage or control in patients with COPD during exercise and / or the immediate post-exercise, using the following parameters:~Tidal volume (VT), respiratory rate (RR), minute volume (MV), inspiratory time (Tins) and expiratory (T exp).~Change in volumes of total and regional chest magazines (pulmonary rib cage, abdominal rib cage and abdomen).~Diaphragmatic mobility.~electrical muscle activity~endurance time.~Dyspnea sensation.
