Fig. 1 Effects of high-intensity interval training (HIIT) on mitochondrial O2 consumption rate (OCR) and bioenergetics health index of the intact platelets in patients with heart failure. GHC, general health care; ATP, ATP-linked OCR; Leak, proton leak; OCR; RESERVE, the reserve capacity of OCR; ROX, residual O2 consumption. *P < 0.05, Pre-intervention vs. Post-intervention; +P < 0.05, HIIT vs. GHC. Values were mean ± SD. International Journal of Cardiology , DOI: ( /j.ijcard ) Copyright © 2018 Elsevier B.V. Terms and Conditions
