Abstract
The purpose of this study was to develop regression equations to predict (VO2) max and (VO2/kg) max in a cross section of normal, not pre-selected adolescents. Forty students had (VO2) max measured on a cycle ergometer. Age, sex, height, weight, percentage of body fat (estimated), thigh circumference, and anterior thigh skin fold were measured. Sexual maturity rating was estimated using the method of Duke and performance on the 12 minute and 1.5 mile runs was recorded. Of the run performances, 1.5 mile run speed had the highest correlation with (VO2) max (r=0.57) and (VO2/kg) max (r=0.72). Of all variables, height had the highest correlation with (VO2> max (r=0.79). Using multiple stepwise regression analysis, equations were developed to predict (VO2) max and (VO2/kg) max: (VO2) max (liters/min) = -0.56926 x 10−2 (1.5 mile run speed) + 3.4187 x 10−1 (height) 0.41689 (sex) + 0.38177 x 10−1 (thigh circumference) -5.348 (r=0.92, R2=0.85, p<.001). (VO2/kg) max (cc/kg/min) = 0.13499 (1.5 mile run speed) - 2.3233 (age) - 5.3145 (sex) + 59.39 (r=0.82, R2=0.67, p<.001). Estimated sexual maturity rating did not contribute significantly to the variance. These equations were cross validated six months later when all runs and measurements were repeated including (VO2) max. Predicted (VO2) max correlated with measured (VO2) max (r=0.92, R2=0.85, p=10−5) and predicted (VO2/kg) max correlated with measured (VO2/kg) max (r=0.76, R20.58, p=10-5). These results suggest regression equations which can accurately estimate (VO>kg) max and (VO/kg) max in a cross section of normal adolescents.
