Investigating the reproducibility of maximal oxygen uptake responses to high-intensity interval training

ConclusionsOur ANOVA results confirmed that the three-month washout period returned VO2max and TTF levels to baseline and prevented carryover effects. Contrary to our hypothesis, our results suggest that individual observed VO2max and TTF responses to identical training stimuli are not reproducible.Practical implications•Two four-week periods of high-intensity interval training resulted in similar mean changes in maximal oxygen uptake (VO2max) and time to fatigue (TTF).•However, individual changes in VO2max and TTF following two identical periods of high-intensity interval training were not reproducible.•These findings highlight a potential challenge for determining whether an individual has benefitted from a given exercise prescription.
