Abstract
The purpose of this study was to address if there is an association between the plateau at VO2max and the anaerobic capacity. 9 well-trained cyclists (age 22.2 +/- 3.5 yr, height 182.5 +/- 5.0 cm, mass 75.7 +/- 8.7 kg, VO2max 59.3 +/- 4.8 ml/kg/min completed both an incremental step test of 20 W/min starting at 120 W for determination of maximal oxygen uptake (MOU) and a maximally accumulated oxygen deficit (MAOD) trial at 125% MOU for estimation of anaerobic capacity. Throughout all trials expired air was recorded on a breath-by-breath basis. A significant inverse relationship was observed between the MAOD and the Δ VO2 during the final 60 s of the MOU test (r=−0.77, p=0.008). Of the 9 participants it was noted that only 4 exhibited a plateau at MOU. There were non-significant differences for VO2 and the associated secondary criteria for those exhibiting a plateau and the non-plateau responders, despite a significant difference for MAOD (p=0.041) between groups. These data suggest that incidence of the plateau at MOU is dependent on anaerobic substrate metabolism and that ranges of responses reported in the literature may be a consequence of variations in anaerobic capacity amongst participants.
