During exhaustive ramp-incremental cycling tests, the incidence of O₂ uptake (V̇O₂) plateaus is low. To verify the attainment of maximum V̇O₂ (V̇O_2max), it is recommended that a trial at a power output (PO) corresponding to 110% of the ramp-derived peak (PO_peak) is performed. It remains unclear whether verification trials set at this PO can be tolerated for long enough to allow attainment of V̇O_2max. Eleven recreationally-trained individuals performed five ramp tests of varying slope (5, 10, 15, 25, 30 W·min^-1), each followed, in series, by two verification trials: the 1^st at 110%PO_peak of the 25 W·min^-1 ramp and the 2^nd at 110% PO_peak attained in the preceding ramp test. Exercise duration of the 1^st verification trial was on average 81±15 s (CV=9±3%) versus 162±32, 121±24, 103±15, and 73±10 s for the 2^nd verification trials at 110% of PO_peak of the 5, 10, 15, and 30 W·min^-1 ramp tests, respectively (P<0.05). Compared to the highest V̇O₂ recorded during ramp tests, V̇O₂ from the subsequent verification trials were not different for the 5, 10, and 15 W·min^-1 ramp tests (P>0.05), but lower for the 25 and 30 W·min^-1 ramp tests (P<0.05). Verification trials at 110%PO_peak of rapidly-incrementing ramp tests (i.e., 25 W·min^-1) were not sustained for long enough to allow the attainment of V̇O_2max. With commonly used rapidly-incrementing ramp tests engendering exhaustion within 8-12 min, verification trials <PO_peak should be preferred as they can be sustained sufficiently long to allow the attainment of V̇O_2max.

在斜坡增量练习后评估 supra-POpeak 验证试验的适用性，以确认达到最大 O2 吸收。

在详尽的斜坡增量循环测试中，O ₂吸收 (V̇O ₂ ) 平台的发生率很低。为了验证是否达到最大 V̇O ₂ (V̇O _2max )，建议在对应于斜坡衍生峰值(PO _peak ) 110% 的功率输出 (PO) 下进行试验。尚不清楚在此 PO 上设置的验证试验是否可以容忍足够长的时间以允许达到 V̇O _2max。十一娱乐性训练的个体进行变化的坡度的斜坡5个测试（5，10，15，25，30瓦·分钟^-1）由两个验证试验中，每个随后，串联：1^日110％PO_峰的25瓦·分钟^-1斜坡和2^次在110％PO_峰前述斜坡测试实现。^第一次验证试验的运动持续时间平均为 81±15 秒（CV=9±3%），而^第二次验证试验的平均持续时间为162±32、121±24、103±15 和 73±10 秒（110%）分别在 5、10、15和 30 W·min ^-1斜坡试验中的 PO_峰值(P<0.05)。与斜坡测试期间记录的最高 V̇O ₂相比，来自后续验证试验的V̇O ₂在 5、10 和 15 W·min ^-1斜坡测试中没有差异（P>0.05），但在 25 和 30 W 时较低·min ^-1斜坡测试（P<0.05）。110%PO 时的验证试验快速增加斜坡测试的_峰值（即，25 W·min ^-1）没有持续足够长的时间以允许达到 V̇O _2max。由于常用的快速递增斜坡测试会在 8-12 分钟内产生疲劳，因此应首选验证试验 <PO_峰值，因为它们可以持续足够长的时间以达到 V̇O _2max。
