Abstract

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 [latin capital V with dot above]o2max (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 [latin capital V with dot above]o2max (l min-1) were obtained from the subjects' height, and the [latin capital V with dot above]o2(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%). [latin capital V with dot above]o2max (ml kg-1min-1) was predicted with similar accuracy (CV=+/-8.4%) from age, and heart rate, [latin capital V with dot above]CO2(l min-1), [latin capital V with dot above]o2 (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 [latin capital V with dot above]o2max slightly, both in l min ([Latin capital letter X with macron above]=-0.09 1 min) and ml kg min ([Latin capital letter X with macron above]=-2.2 ml kg min, P<0.05). The results indicate that reasonably reliable and accurate estimates of [latin capital V with dot above]o2max for children may be obtained from either laboratory data, or simply from their age, height and weight.
