What is the central question of this study? Ischaemic preconditioning is a novel pre‐exercise priming strategy. We asked whether ischaemic preconditioning would alter mitochondrial respiratory function and pulmonary oxygen uptake kinetics and improve severe‐intensity exercise performance. What is the main finding and its importance? Ischaemic preconditioning expedited overall pulmonary oxygen uptake kinetics and appeared to prevent an increase in leak respiration, proportional to maximal electron transfer system and ADP‐stimulated respiration, that was evoked by severe‐intensity exercise in sham‐control conditions. However, severe‐intensity exercise performance was not improved. The results do not support ischaemic preconditioning as a pre‐exercise strategy to improve exercise performance in recreationally active participants.
