: The incremental exercise test is commonly used to measure maximal oxygen uptake (VOmax), but an additional verification test is often recommended as the "gold standard" to confirm the true VOmax. Therefore, the aim of this study was to compare the peak oxygen uptake (VOpeak) obtained in the ramp incremental exercise test and that in the verification test performed on different days at submaximal intensity. Additionally, we examined the roles of anaerobic performance and respiratory muscle strength. : Sixteen physically active men participated in the study, with an average age of 22.7 ± 2.4 (years), height of 178.0 ± 7.4 (cm), and weight of 77.4 ± 7.3 (kg). They performed the three following tests on a cycle ergometer: the Wingate Anaerobic Test (WAnT), the ramp incremental exercise test (IET), and the verification test performed at an intensity of 85% (VER) maximal power, which was obtained during the IET. : No significant difference was observed in the peak oxygen uptake between the IET and VER ( = 0.51). The coefficient of variation was 3.1% and the Bland-Altman analysis showed a high agreement. We found significant correlations between the total work performed in the IET, the anaerobic peak power (r = 0.52, ≤ 0.05), and the total work obtained in the WAnT (r = 0.67, ≤ 0.01). There were no significant differences in post-exercise changes in the strength of the inspiratory and expiratory muscles after the IET and the VER. : The submaximal intensity verification test performed on different days provided reliable values that confirmed the real VOmax, which was not limited by respiratory muscle fatigue. This verification test may be suggested for participants with a lower anaerobic mechanical performance.
递增运动试验常用于测量最大摄氧量（VO₂max），但通常建议进行额外的验证试验作为“金标准”来确认真正的VO₂max。因此，本研究的目的是比较在递增运动试验中获得的峰值摄氧量（VO₂peak）与在不同日子以次最大强度进行的验证试验中获得的峰值摄氧量。此外，我们还研究了无氧运动能力和呼吸肌力量的作用。
16名身体活跃的男性参与了本研究，平均年龄为22.7±2.4（岁），身高为178.0±7.4（厘米），体重为77.4±7.3（千克）。他们在功率自行车上进行了以下三项测试：温盖特无氧试验（WAnT）、递增运动试验（IET）以及以递增运动试验中获得的最大功率的85%强度进行的验证试验（VER）。
递增运动试验和验证试验之间的峰值摄氧量没有显著差异（P = 0.51）。变异系数为3.1%，布兰德-奥特曼分析显示一致性较高。我们发现递增运动试验中完成的总功、无氧峰值功率（r = 0.52，P≤0.05）以及温盖特无氧试验中获得的总功之间存在显著相关性（r = 0.67，P≤0.01）。递增运动试验和验证试验后吸气肌和呼气肌力量的运动后变化没有显著差异。
在不同日子进行的次最大强度验证试验提供了可靠的值，证实了真正的VO₂max，且不受呼吸肌疲劳的限制。对于无氧机械性能较低的参与者，可能建议进行这种验证试验。
