Abstract
Abstract The purposes of this study were, first, to investigate the relationship between maximal oxygen intake and three submaximal work parameters (heart rate, oxygen intake, and respiratory quotient), and second, to develop regression equations for the estimation of maximal oxygen intake. Sixty boys, ranging in age from 12–15 years, were given a series of treadmill tests designed to elicit submaximal work parameters as well as maximal oxygen intake values. The data were treated by stepwise multiple correlation-regression analysis to obtain correlation coefficients between the various submaximal measures and maximal oxygen intake, and to obtain regression equations for estimating maximal oxygen intake. The .05 level was used to determine the significance of the correlation coefficients. Acceptable regression equations for estimation of maximal oxygen intake required a multiple correlation coefficient equal to or larger than .700. For both groups of boys (12–13 years old and 14–15 years old) only the subm...
