BONEN, A., V.H. HEYWARD, K.J. CURETON, R.A. BOILEAU, and B.H. MASSEY. Prediction of maximal oxygen uptake in boys, ages 7-15 years. Med. Sci. Sports. Vol. 11, No. 1, pp. 24-29, 1979. Predictions of V̇o2max (l min-1 and ml kg-1min-1) were obtained via multiple regression procedures from a sample of 100 boys, ages 6.7-14.8 years. Prediction equations for V̇o2max (l min-1) were obtained from the subjects' height, and the V̇o2(l min-1) and heart rate observed during the third min of a treadmill walk (R=0.95; CV= ±9.3%). A similar prediction was obtained when the subjects' age, height and weight were used (R=0.94; CV= ±9.7%). V̇o2max (ml kg-1min-1) was predicted with similar accuracy (CV=±8.4%) from age, and heart rate, V̇CO2(l min-1), V̇o2 (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%. However, the equations based on age, height and weight underestimated the V̇o2max slightly, both in l min (JOURNAL/masis/04.02/00005756-197901110-00006/OV0398/v/2018-02-08T152416Z/r/image-png=-0.09 1 min) and ml kg min (JOURNAL/masis/04.02/00005756-197901110-00006/OV0398/v/2018-02-08T152416Z/r/image-png=-2.2 ml kg min, P<0.05). The results indicate that reasonably reliable and accurate estimates of V̇o2max for children may be obtained from either laboratory data, or simply from their age, height and weight.
