Pulmonary Disease, Chronic Obstructive
Conditions
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.
Interventions
OTHERStretching
Stretching of the rib cage muscles
OTHERControl
Rest without stretching (sham)
OTHERExercise
Constant load exercise on a bike

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