The purpose of this study was to develop an age-generalized regression model to predict maximal oxygen uptake (V[O.sub.2max]) based on a maximal treadmill graded exercise test (GXT; George, 1996). Participants (N= 100), ages 18-65 years, reached a maximal level of exertion (mean [+ or -] standard deviation [SD]; maximal heart rate [[HR.sub.max]]= 185.2 [+ or -] 12.4 beats per minute (bpm); maximal respiratory exchange ratio [[RER.sub.max]] = 1.1810.05; maximal rating of perceived ...
