title: Exercise limitation in obstructive lung disease.
abstract: 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).
