Fig. 2.

Comparisons of pre- versus post-surgery VO₂ at the VT (gray) and at peak exercise (white). VO₂ is expressed in absolute value (a), adjusted for LM (b), and adjusted for body weight (BW) (c). Six months after bariatric surgery, VO₂peak relative to BW increased due to weight loss, absolute VO₂peak, and VO₂ relative to LM remained unchanged and the absolute VT was reduced. *p < 0.05, **p < 0.01.
