Figure 3. Proportional oxygen consumption/ maximal estimated oxygen consumption (VO₂/VO₂max %) ratio at the end of the group of resting activities (A)(lateral and dorsal lying, sitting and standing positions); of personal care (B) (morning hygiene, bathing, putting on and taking off clothes and shoes); of labor activities (C) (domestic and office activities, walking up and down a flight of stairs and ramp); and of efforts activities (D) (walking with 2.5 Kg in each hand and walking with 5.0 Kg in one hand) stratified by the GOLD spirometric classification (mild, moderate, severe and very severe).

Mean±standard error. *p<0.01 - mild vs. moderate, severe and very severe; ^#p<0.01 - moderate vs. severe and very severe; ^$p<0.05 – severe vs. very severe; ** p<0.01 - mild vs. severe and very severe. Short title: Proportional oxygen consumption/ maximal estimated oxygen consumption (VO₂/VO₂max %) ratio after the performed ADL.
