Divergent functional responses to hyperoxic versus hypoxic high-intensity interval training: a randomized exploratory active-comparator study
Inspired oxygen fraction (FiO₂) may alter the internal physiological cost of supramaximal interval training. This randomized exploratory active-comparator study compared functional adaptations to hyperoxic versus hypoxic Tabata-format high-intensity interval training (HIIT). Twenty-three physically activ...
