Submaximal and supramaximal square-wave bouts have been reported to consistently verify 'true' VO2max. Although a direct comparison between both protocols exists, knowledge on the statistical consistency between the protocols using the same group of participants is lacking. The purpose of this study was to conduct an analysis of the submaximal and supramaximal verification bout performed shortly subsequent to a graded exercise test (GXT). On 2 separate occasions, 6 males and 7 females (age: 29±9 years) completed a GXT protocol and an exhaustive, square-wave bout at either end-GXT power minus 2-stages or 105% end-GXT power. No differences (p>0.05) in VO2max were observed between the GXT and square-wave bouts. The typical error (ml/kg/min) for submaximal (1.09) and supramaximal (1.04) trials was similar. Likewise, similar relative measures of consistency were observed for the submaximal (ICC α=0.97, CV=2.4%) and supramaximal trials (ICC α=0.95, CV=2.3%). For a GXT lasting ~10-12 min, the submaximal or supramaximal protocols appear to be equally effective.
短时间的次最大和最大方波冲刺被报道为一致地验证“真实”的最大摄氧量。虽然这两种方案之间存在直接的比较，但对于使用相同参与者组的方案之间的统计学一致性的了解是缺乏的。本研究的目的是分析在递增运动测试（GXT）后立即进行的次最大和最大验证冲刺。在 2 个不同的场合，6 名男性和 7 名女性（年龄：29±9 岁）完成了 GXT 方案和在 GXT 结束功率减去 2 阶段或 105%GXT 结束功率的彻底的、方波冲刺。在 GXT 和方波冲刺之间没有观察到最大摄氧量的差异（p>0.05）。次最大（1.09）和最大（1.04）试验的典型误差（ml/kg/min）相似。同样，对于次最大（ICC α=0.97，CV=2.4%）和最大试验（ICC α=0.95，CV=2.3%），也观察到类似的一致性相对措施。对于持续约 10-12 分钟的 GXT，次最大或最大方案似乎同样有效。
