Summary
Previous studies suggest that treadmill exercise may be a more relevant exercise stimulus
than the cycle ergometer to demonstrate benefits with bronchodilator therapy in patients with
COPD. The hypothesis of the study is that patients with COPD will exhibit greater
improvements in exercise endurance and breathlessness with arformoterol compared with normal
saline during treadmill walking than with cycle exercise.
