Effects of Respiratory Muscle Training and Respiratory Exercise in Exercise Tolerance, Performing Daily Life Activities and Quality of Life of Patients With Chronic Obstructive Pulmonary Disease

Summary

In patients with chronic obstructive pulmonary disease (COPD) breaths at an abnormally high lung volume causes the inspiratory muscle to operate at non-optimal lengths, which reduce their maximal contractile forces. In addition, causes non thoraco abdominal synchronize, reduced inspiratory muscle strength and is associated with dyspnea and decreased exercise capacity. For these patients inspiratory muscle training (IMT) is a widely employed form of rehabilitation also targeting the respiratory muscle. In addition, patients often experience shortness of breath and a decline in exercise tolerance, resulting in disability in the performance of activities of daily living (ADL). The aims of this trial are to evaluate the effects of inspiratory muscle training associated with aerobic training on strength and endurance of inspiratory muscle, thoracic abdominal synchrony, exercise tolerance and quality of life patients with COPD. To compare the responses with the effects of aerobic training plus exercises of the trunk and upper limbs, and stretching of large muscle groups of the trunk. To compare difference in the perception of dyspnea during the ADL set (Borg Scale) with perception of dyspnea self-reported in the Medical Research Council (MRC), the London Chest Activity of Daily Living (LCADL) and the Pulmonary Functional Status and Dyspnea Questionnaire - Modified version (PFSDQ-M) before start the protocol. To investigate changes on perception of dyspnea (Borg scale), metabolic and ventilatory responses during a standard set of ADL tasks after a physical training and to evaluate and compare changes on perception of dyspnea. The hypothesis are that the ventilatory efficiency during the performance of ADL and the dyspnea reported from borg scale, the LCADL and the PFSDQ-M that quantifies the functional performance (change in activity levels) are improved during the IMT in conjunction with general exercise training in patients with COPD. The MIT increases the strength and endurance of inspiratory muscle, the exercise capacity and the quality of life compared to the general physical training. However, compared to the thorax abdominal synchronizes, higher modification is verified in the general physical training group with specific exercise to torso, limbs and stretching of the higher muscle group.

Conditions

• Chronic Obstructive Pulmonary Disease

Interventions

OTHER

Inspiratory muscle training

A group will be associated with inspiratory muscle training (GTMI). The inspiratory muscle strength training will be done in the POWERbreathe ®, and the patient will breathe for two minutes, seven times with one minute rest between them, with 15% MIP, the first week, then, increased 5-10% to reach 60% of the initial MIP after four weeks. After the first month, every fifteen days the charge will be adjusted to 60% of the new value of MIP. The breathing pattern will remain free

OTHER

Respiratory exercise

Specific exercise program for mobility and biomechanics of the rib cage, as exercises of the trunk and upper limbs, and stretching of large muscle groups of the trunk.
