Exercise limitation in obstructive lung disease

Chest. 1998 Oct;114(4):965-8. doi: 10.1378/chest.114.4.965.


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

Setting: University Hospital Pulmonary Function Laboratory.

Subjects: 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.

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