Study Design

Allocation randomized
Intervention model crossover assignment
Masking double blind (subject, investigator)
Primary purpose treatment
Arm
(Experimental)
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
stretching
Stretching of the rib cage muscles
exercise
Constant load exercise on a bike
(Sham Comparator)
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.
control
Rest without stretching (sham)
exercise
Constant load exercise on a bike

Primary Outcomes

Measure
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

Measure
Diaphragm mobility measured by ultrasound
time frame: 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
time frame: 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
time frame: Participants will be followed for the duration of the stretching and the exercise, an expected average of 60 minutes

Eligibility Criteria

Male or female participants from 50 years up to 80 years old.

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.

Principal investigator Adriane Cardim, Graduated
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.
