Study Overview
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.

Arms & Interventions
Stretching and Exercise
This group undergo a session of stretching aiming flexibility of the rib cage and later at an exercise test with constant load up to the limit of tolerance for exercise bike
Intervention: Stretching (Other)

Intervention: Exercise (Other)
Control and Exercise
This group will carry out the exercise test with constant load up to the limit of tolerance for exercise bike after a period of rest under the same environmental conditions and the experimental group time. During this time the therapist will place their hands but not performing the stretch.

Outcomes
Primary Outcomes
Endurance tolerance as measured by the duration of the exercise
Time Frame: Participants will be followed for the duration of the exercise, an expected average of 10 minutes
Dyspnea as measured by Borg Escale
Time Frame: Participants will be followed for the duration of the exercise, an expected average of 10 minutes
Secondary Outcomes
- 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)
