Brief summary: Investigate the effects of stretching the muscles of the rib cage in individuals with COPD during exercise.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

* Smoking history, occupational or environmental exposure to pollutants and / or symptoms of cough, dyspnea or hypersecretion;
* FEV1 \<80% predicted and post-bronchodilator FEV1 / FVC \<70% to confirm the diagnosis of airway obstruction not fully reversible bronchodilator therapy;
* Absence of co-morbidities that does not allow the realization of stress (hypertension, severe pulmonary hypertension, myocardial infarction, congestive heart failure, severe dyspnoea);
* Preserved cognitive functioning;
* Sedentary
* Clinically stable during the study period.

Exclusion Criteria:

* Patients with cognitive, hearing or visual deficit;
* Changes in the neuro-musculo-skeletal system which endangers or impairs the assessment;
* Obese
* Not be able to achieve at least three stages of the incremental test.

Primary outcomes:
measure: Endurance tolerance as measured by the duration of the exercise
timeFrame: Participants will be followed for the duration of the exercise, an expected average of 10 minutes
measure: Dyspnea as measured by Borg Escale
timeFrame: Participants will be followed for the duration of the exercise, an expected average of 10 minutes
Secondary outcomes:
measure: Diaphragm mobility measured by ultrasound
timeFrame: Participants will be followed for the duration of the stretching and the exercise, an expected average of 60 minutes
measure: Volumes of the chest wall measured by pletismography optoelectronic
timeFrame: Participants will be followed for the duration of the stretching and the exercise, an expected average of 60 minutes
measure: Muscle electrical activity measured by surface electromyography
timeFrame: Participants will be followed for the duration of the stretching and the exercise, an expected average of 60 minutes
