To answer this. At a superficial level a-vO2 difference has not changed so seems like no change in O2 extraction. But arterial O2 flow (QaO2) has doubled from 3 to 6 L/min. To maintain a-vO2 difference, peripheral O2 diffusion (DO2) has to actually double.

Western Health Sciences Juan Murias Faricier Robin International Journal of Cardiology We show that 3/4 of patients referred to cardiac rehab DO NOT achieve a reliable change in VO2peak despite 6 months of aerobic exercise training. We can and must do better!
