IC was decreased by (median) 580ml (range 90-1180ml) during exercise, indicating dynamic hyperinflation. Inspiratory reserve volume at peak exercise was 445ml (241-1350ml) indicating mechanical constraint on the respiratory system. The exercise tidal flow met or exceeded the expiratory boundary of the maximal flow volume loop over 72% of the expiratory volume (range 40-90%), indicating expiratory flow limitation. Reduced BR as a sole criterion underestimates ventilatory limitation during exercise in mild to modera
