COPD and Exercise
COPD is a progressive lung disease that causes persistent airway obstruction. This can happen because of emphysema, or chronic bronchitis. A COPD sufferer will have a lot of difficulty in breathing and may have a chronic cough or wheezing. Other signs and symptoms include reduced lung elastic recoil and limitation in air flow; breathing will become much harder to do; the breathing muscles will become weak because of hyperinflation, which overly stresses these muscles; and other ventilation-related signs. People with COPD will have difficulty in emptying their lungs and impaired gas exchange in emphysema because of destruction of the alveolar-capillary membrane.
However, exercise can improve the use of oxygen, exercise (work) capacity, and can lower the anxiety level of COPD patients. Some of the direct benefits of exercise in this case include:
