The purpose of this study was to determine the validity and reliability of three of the most commonly used field tests to predict maximum oxygen uptake in children and adolescents. VO2max was directly measured during a maximal treadmill test in 90 children (10-18 yrs). Each subject also performed, in duplicate, a timed distance run (1 mile), a step test, and a submaximal cycle ergometer test. A multiple regression equation was developed with directly measured VO2max as the dependent variable and mile-run time, gender, skinfold thickness, and body weight as independent variables. The equation had a multiple R=0.84 and a standard error of estimate of 9%, or 4.3 ml/kg/min. The results suggest that when the three most commonly used field tests to predict aerobic capacity are compared in the same group of children, the timed distance run is superior in both validity and reliability.
