Abstract

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.

评估运动能力的非最大测试的比较

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，但它们在健身或临床运动项目中并不广泛。本研究比较了使用非运动预测（Matthews，Heil，Freedson&Pastides，1999）、RPE外推到19和20（Eston，Lambrick，Sheppard&Parfitt，2008）和Rockport步行测试（RWT）（Kline等人，1987）对健康久坐志愿者的VO2max的预测，以及使用Talk测试（Foster等人，2018）和RPE@13,14,15对VT的预测。受试者进行了带气体交换的GXT跑步机、带RPE和Talk测试的次最大跑步机、RWT和Matthews非运动评估。所有方法都提供了VO2max和VT的合理估计，相关性>0.75和SEE~1MET。VO2max的最佳估计方法是外推到RPE=19。在TT的最后阳性和等声阶段之间以及RPE13和14之间观察到VT。非最大评估，甚至非运动方程可以用作气体交换最大GXT的替代，以对VO2max和VT进行合理估计。

期刊介绍： Kinesiology – International Journal of Fundamental and Applied Kinesiology (print ISSN 1331- 1441, online ISSN 1848-638X) publishes twice a year scientific papers and other written material from kinesiology (a scientific discipline which investigates art and science of human movement; in the meaning and scope close to the idiom “sport sciences”) and other adjacent human sciences focused on sport and exercise, primarily from anthropology (biological and cultural alike), medicine, sociology, psychology, natural sciences and mathematics applied to sport in its broadest sense, history, and others. Contributions of high scientific interest, including also results of theoretical analyses and their practical application in physical education, sport, physical recreation and kinesitherapy, are accepted for publication. The following sections define the scope of the journal: Sport and sports activities, Physical education, Recreation/leisure, Kinesiological anthropology, Training methods, Biology of sport and exercise, Sports medicine and physiology of sport, Biomechanics, History of sport and Book reviews with news.
