The purpose of this study was to develop and cross-validate a generalized equation for predicting VO2peak from 1-mile run/walk (MRW) time and demographic variables in youth and young adults. Data for 753 males and females 8-25 yr of age were divided into validation (N = 495) and cross-validation (N = 258) samples. The validation sample was used to develop a multiple regression equation for predicting treadmill VO2peak (ml.kg-1.min-1) from gender (0 = F, 1 = M), age (yr), body mass index (kg.m-2; BMI) and MRW time (min). The multiple correlation (R) and standard error of estimate (SEE) were: R = 0.71, SEE = 4.8 ml.kg-1.min-1. The accuracy of this equation was confirmed when applied to the cross-validation sample. The regression equation for the total sample was: VO2peak = -8.41 (MRW) + 0.34 (MRW)2 + 0.21 (Age x Gender) -0.84 (BMI) + 108.94, R = 0.72, SEE = 4.8 ml.kg-1.min-1. We conclude that the generalized equation provides valid estimates of VO2peak in youth and young adults. The equation should be useful for educators, clinicians, and researchers who would like to interpret results of the MRW test in terms of VO2peak.
本研究的目的是开发并交叉验证一个通用方程，用于根据青少年和青年的1英里跑/走（MRW）时间及人口统计学变量预测最大摄氧量（VO2peak）。将753名年龄在8至25岁的男性和女性的数据分为验证样本（N = 495）和交叉验证样本（N = 258）。验证样本用于建立一个多元回归方程，以根据性别（0 = 女性，1 = 男性）、年龄（岁）、体重指数（kg·m-2；BMI）和MRW时间（分钟）预测跑步机上的VO2peak（ml·kg-1·min-1）。多元相关系数（R）和估计标准误差（SEE）分别为：R = 0.71，SEE = 4.8 ml·kg-1·min-1。将该方程应用于交叉验证样本时，证实了其准确性。总样本的回归方程为：VO2peak = -8.41（MRW）+ 0.34（MRW）2 + 0.21（年龄×性别）-0.84（BMI）+ 108.94，R = 0.72，SEE = 4.8 ml·kg-1·min-1。我们得出结论，该通用方程能够有效估计青少年和青年的VO2peak。该方程对于希望根据VO2peak来解释MRW测试结果的教育工作者、临床医生和研究人员应是有用的。
