| Description | Maximal oxygen uptake $(VO_{2}$max) is strongly associated with endurance performance as well as health risk. Despite the fact that $VO_{2}$max has been measured in exercise physiology for over a century, robust procedures to ensure that $VO_{2}$max 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 $VO_{2}$max 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’ $VO_{2}$max in this sample. Results demonstrated that VER is a safe and suitable approach to confirm attainment of $VO_{2}$max in unhealthy adults and children, as in most studies VER-derived $VO_{2}$max is similar of that obtained in GXT. However, many individuals reveal higher $VO_{2}$max in response to VER and protocols used across studies vary, which merits additional work identifying if an optimal VER protocol exists to elicit ‘true’ $VO_{2}$max in this particular population. |
