Criterion-related validity of the one-mile run/walk test in children aged 8–17 years

Abstract We assessed the criterion-related validity of Cureton's equation for estimating peak oxygen consumption ([Vdot]O2peak) from the one-mile run/walk test in endurance-trained children aged 8–17 years. Altogether, 66 physically active white children and adolescents (32 girls, 34 boys) completed a graded exercise test to volitional exhaustion and the one-mile run/walk test. Cureton's equation was used to estimate [Vdot]O2peak, and was assessed using several error measures. Agreement between measured [Vdot]O2peak and estimated [Vdot]O2peak was analysed by the Bland and Altman method. The correlation coefficient between measured [Vdot]O2peak and one-mile run/walk time was −0.59 (P < 0.001) and that between measured and estimated [Vdot]O2peak was 0.70 (P < 0.001). The mean difference between measured and estimated [Vdot]O2peak was 10 ml · kg−1 · min−1 (95% CI = 9.2–11.8; P < 0.001). The standard error of the estimate was 3 ml · kg−1 · min−1, and the percentage error was 32%. There was a positive associat...
