RSH1, RSH2 – participants with RSH training, SIH1, SIH2 – participants with SIH training. ROUTINE respiration (R) and electron transfer capacity (E) were determined as described in the methods section. IO2 – oxygen flow per cell count [amol·s-1·cell-1 = pmol·s-1·10-6 cells], JO2 – oxygen flux per mitochondrial marker citrate synthase activity [pmol·s-1·IU-1] 37. Respiration was corrected for the contribution from PLTs contaminating the PBMC fraction. Rox – residual oxygen consumption.
