Linear regressions between systolic indices, peripheral oxygen extraction, and peak oxygen uptake. A significant positive linear correlation exists between S’ (A) at peak/change in S’ and VO2peak (B), as well as between GLS at 4 min and VO2peak (C) and change in GLS and VO2peak (D). A positive linear correlation was also observed between Δ(a-v)O2 and GLS at 4 min (E) and change in GLS (F)
