简要总结
Investigate the effects of stretching the muscles of the rib cage in individuals with COPD during exercise.
详细描述
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.

干预措施: 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.
