Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Stable subjects will attend for testing on three days. First day, lung function and incremental cycle and treadmill tests to peak work capacity (randomised order) will be performed. On the second and third day, subjects will be randomised to perform 20 minutes of endurance exercise at 60% of peak work capacity on the cycle ergometer and the treadmill.

None
Comparator / control treatment
Control treatment was resting breathing for 20 minutes.
Control group
Placebo
