Although maximal incremental exercise tests (GXT) are the gold standard for outcome assessment and exercise proscription, they are not widely available in either fitness or clinical exercise programs. This study compared the prediction of VO2max in healthy, sedentary volunteers using a non-exercise prediction (Matthews, Heil, Freedson & Pastides, 1999), RPE extrapolation to 19 & 20 (Eston, Lambrick, Sheppard & Parfitt, 2008) and the Rockport Walking Test (RWT)(Kline et al, 1987) and of VT using the Talk Test (Foster et al., 2018) and RPE @ 13,14,15. Subjects performed treadmill GXT with gas exchange, submaximal treadmill with RPE and Talk Test, the RWT and the Matthews non-exercise estimation. All methods provided reasonable estimates of both VO2max and VT, with correlations >0.75 and SEE ~1 MET. VO2max was best estimated with extrapolation to RPE=19. VT was observed intermediate between the Last Positive & Equivocal stages of the TT and between RPE 13 & 14. Non-maximal evaluation, and even non-exercise equations can be used as a substitude for maximal GXT with gas exchange to make reasonable estimates of both VO2max and VT.

非最大测验估计运动能力的比较

尽管最大增量运动测试（GXT）是评估结果和禁止运动的金标准，但在健身或临床运动计划中并未广泛使用。这项研究使用非运动预测（Matthews，Heil，Freedson＆Pastides，1999），RPE外推至19和20（Eston，Lambrick，Sheppard＆Parfitt，2008）和Rockport比较了健康久坐的志愿者对VO2max的预测。步行测试（RWT）（Kline等，1987）和VT的谈话测试（Foster等，2018）和RPE @ 13,14,15。受试者进行了带有气体交换的跑步机GXT，具有RPE和Talk Test的次最大跑步机，RW​​T和Matthews非运动估计。所有方法均提供了VO2max和VT的合理估计值，相关系数> 0.75且SEE〜1 MET。最好将VO2max估计为RPE = 19。在TT的最后正向和模糊阶段之间以及RPE 13和14之间观察到VT。非最大评估，甚至非运动方程式也可以用作最大GXT的次要条件，可以进行气体交换，从而合理地估算两者VO2max和VT。
