Maximal oxygen uptake (VO₂max) is strongly associated with endurance performance as well as health risk. Despite the fact that VO₂max has been measured in exercise physiology for over a century, robust procedures to ensure that VO₂max is attained at the end of graded exercise testing (GXT) do not exist. This shortcoming led to development of an additional bout referred to as a verification test (VER) completed after incremental exercise or on the following day. Workloads used during VER can be either submaximal or supramaximal depending on the population tested. Identifying a true VO₂max value in unhealthy individuals at risk for or having chronic disease seems to be more paramount than in healthy and active persons, who face much lower risk of premature morbidity and mortality. This review summarized existing findings from 19 studies including 783 individuals regarding efficacy of VER in unhealthy individuals to determine its efficacy and feasibility in eliciting a ‘true’ VO₂max in this sample. Results demonstrated that VER is a safe and suitable approach to confirm attainment of VO₂max in unhealthy adults and children, as in most studies VER-derived VO₂max is similar of that obtained in GXT. However, many individuals reveal higher VO₂max in response to VER and protocols used across studies vary, which merits additional work identifying if an optimal VER protocol exists to elicit ‘true’ VO₂max in this particular population.

验证测试用于确认不健康参与者达到最大摄氧量的效用：透视审查

最大摄氧量 (VO ₂ max) 与耐力表现和健康风险密切相关。尽管 VO ₂ max 已经在运动生理学中测量了一个多世纪，但不存在确保在分级运动测试 (GXT) 结束时达到VO ₂ max 的稳健程序。这一缺陷导致开发了一个额外的回合，称为在增量练习后或第二天完成的验证测试 (VER)。VER 期间使用的工作负载可以是次最大或超最大，具体取决于测试的人群。识别真正的 VO ₂有慢性病风险或患有慢性病的不健康个体的最大价值似乎比健康和活跃的人更为重要，后者面临的过早发病和死亡风险要低得多。本综述总结了 19 项研究（包括 783 名个体）的现有发现，这些研究涉及 VER 在不健康个体中的功效，以确定其在该样本中引发“真实”最大摄氧量_{2 的}功效和可行性。结果表明，VER 是确认不健康成人和儿童达到 VO ₂ max的安全且合适的方法，因为在大多数研究中，VER 衍生的 VO ₂ max 与在 GXT 中获得的类似。然而，许多人表现出更高的 VO ₂max 响应 VER 和跨研究使用的协议各不相同，这值得进行额外的工作，以确定是否存在最佳 VER 协议以在该特定人群中引发“真实”VO ₂ max。
