Exercise limitation in obstructive lung disease.
OBJECTIVE
To study the relationship of resting pulmonary function to maximal exercise power output (Wmax) in obstructive lung disease (OLD).


METHODS
University Hospital Pulmonary Function Laboratory.


METHODS
Twenty-five patients with OLD (6 with asthma and 19 with COPD).


METHODS
Measurement of pulmonary lung function, resting arterial blood gases, and maximal symptom-limited exercise on a cycle ergometer.


CONCLUSIONS
In OLD, the only significant contributor to Wmax was the inspiratory capacity (r2 = 0.66; p < 0.001).
