What is the Next Step in the
Treatment of COPD Therapy?
• New bronchodilator therapy ?
• New anti-inflammatory therapy ?
• Reduction the number of exacerbations
?
• Alveolar grow factor ?

Exercise training has favourable effect in
COPD. High intensity continous training is
more effective compared to low intensity
training.

acidosis and ventilation as a result of exercise training in patients with
chronic obstructive lung disease. Am Rev Respir Dis 1991; 143:9-18.
