Abstract
Predictions of .ovrhdot.VO2 max [maximal O2 uptake] (l min-1 and ml kg-1 min-1) were obtained via multiple regression procedures from 100 boys, ages 6.7-14.8 yr. Prediction equations for .ovrhdot.VO2 max (l min-1) were obtained from the subjects'' height, and the .ovrhdot.VO2 (l min-1) and heart rate observed during the 3rd min of a treadmill walk (R [multiple regression coefficient] = 0.95; CV [coefficient of variability] = .+-. 9.3%). A similar prediction was obtained when the subjects'' age, height and weight were used (R = 0.94; CV = .+-. 9.7%). .ovrhdot.VO2 max (ml kg-1 min-1) was predicted with similar accuracy (CV = .+-. 8.4%) from age, and heart rate, .ovrhdot.VCO2[maximal CO2 output](l min-1), .ovrhdot.VO2 (ml kg min-1) or from simply age, height and weight) (CV = .+-. 9.2%). Cross-validation of the equations with another sample of 39 boys demonstrated that the prediction equations based on laboratory data were quite stable, % errors approximately 1-2 .+-. 9%. The equations based on age, height and weight underestimated the .ovrhdot.VO2 max slightly, in l min (.hivin.X = -0.09 l min) and ml kg min (.hivin.X = -2.2 ml kg min, P < 0.05). Reasonably reliable and accurate estimates of .ovrhdot.VO2 max for children may be obtained from laboratory data or simply from their age, height and weight.
