A, Power to detect percentage change in mitochondrial respiration (effect size) after a training intervention with n = 20 participants. A minimum of ~11% increase in mitochondrial respiration is needed to be detected at 80% power for both the CI+CIIP and CI+CIIE, if each participant had duplicate respiration measurements. B, Power to detect percentage change in mitochondrial respiration ratios (effect size) after a training intervention with n = 20 participants. A minimum of ~6% increase for PCR phosphorylation control ratio (CI+IIP/CI+IIE) and ~7% increase for SCR substrate control ratio at constant P (CIP/CI+IIP) is required to be detected at 80% power, if each participant had duplicate respiration measurements
