“…14 Corroborating to this point of view, Gordon et al 23 concluded that there was an inverse correlation between VO ΔVO 2 and the maximum accumulated oxygen deficit (r=-0.77, p-value=0.008), suggesting that plateau occurrence is dependent on anaerobic metabolism and that the wide range of plateau occurrence found in literature may be consequence of the variety of subjects anaerobic capacity. Refuting these findings, Silva et al 24 , with young male athletes, have shown that the anaerobic capacity is not a decisive factor for VO2max determination, finding a non-significant inverse correlation between VO ΔVO 2 and the accumulated maximum oxygen deficit (r = -0.61, p-value = 0.270). On the other hand, these results were obtained from a sample of physically active individuals and not from highly trained athletes, as presented by Gordon et al 23 .…”

Objective: The classic criterion for VO2máx plateau identification was proposed by Taylor et al. (1955), however, there are many critiques of this method. In this paper, we propose a new statistic-based VO2max plateau identification methodology. In addition, we aim to test for eventual differences between characteristics of the individuals who presented and those who did not present the maximum VO2max plateau. Method: Forty-one (n = 41) physically active men participated. The subjects underwent a cardiopulmonary exercise test using ramp protocol to measure the VO2max and other physiological variables. The identification of VO2max plateau was performed by segmented linear regression with unknown breakpoints for each individual. Results: Although 58.54% (24) of the sample presented VO2max plateau, no significant differences were observed in metabolic, ventilatory and velocity variables between the groups. Conclusion: The methodology presents advantages, since it is adequate to analyze VO2 variations individually and because it is based on statistical techniques, which considers the continuous records of the maximal effort test, not segmenting it in sections for analysis. The comparison between groups, according to the occurrence of the plateau, showed no differences between them.

The Oxygen Uptake Plateau—A Critical Review of the Frequently Misunderstood Phenomenon

2021

A flattening of the oxygen uptake–work rate relationship at severe exercise indicates the achievement of maximum oxygen uptake $$\left({\text{VO}}_{2\max } \right)$$ VO 2 max . Unfortunately, a distinct plateau $$\left( {{{\text{VO}}}_{2} {\text{pl}}} \right)$$ VO 2 pl at $${{\text{VO}}}_{2\max }$$ VO 2 max is not found in all participants. The aim of this investigation was to critically review the influence of research methods and physiological factors on the $${{\text{VO}}}_{2} {\text{pl}}$$ VO 2 pl incidence. It is shown that many studies used inappropriate definitions or methodical approaches to check for the occurrence of a $${{\text{VO}}}_{2} {\text{pl}}$$ VO 2 pl . In contrast to the widespread assumptions it is unclear whether there is higher $${{\text{VO}}}_{2} {\text{pl}}$$ VO 2 pl incidence in (uphill) running compared to cycling exercise or in discontinuous compared to continuous incremental exercise tests. Furthermore, most studies that evaluated the validity of supramaximal verification phases, reported verification bout durations, which are too short to ensure that $${{\text{VO}}}_{2\max }$$ VO 2 max have been achieved by all participants. As a result, there is little evidence for a higher $${{\text{VO}}}_{2} {\text{pl}}$$ VO 2 pl incidence and a corresponding advantage for the diagnoses of $${{\text{VO}}}_{2\max }$$ VO 2 max when incremental tests are supplemented by supramaximal verification bouts. Preliminary evidence suggests that the occurrence of a $${{\text{VO}}}_{2} {\text{pl}}$$ VO 2 pl in continuous incremental tests is determined by physiological factors like anaerobic capacity, $${{\text{VO}}}_{2}$$ VO 2 -kinetics and accumulation of metabolites in the submaximal intensity domain. Subsequent studies should take more attention to the use of valid $${{\text{VO}}}_{2} {\text{pl}}$$ VO 2 pl definitions, which require a cut-off at ~ 50% of the submaximal $${{\text{VO}}}_{2}$$ VO 2 increase and rather large sampling intervals. Furthermore, if verification bouts are used to verify the achievement of $${{\text{VO}}}_{{2{\text{peak}}}}$$ VO 2 peak /$${{\text{VO}}}_{2\max }$$ VO 2 max , it should be ensured that they can be sustained for sufficient durations.
