A popular algorithm to predict VO2Peak from the one-mile run/walk test (1MRW) includes body mass index (BMI), which manifests practical issues in school settings. The purpose of this study was to develop an aerobic capacity model from 1MRW in adolescents independent of BMI. Cardiorespiratory endurance data were collected on 90 adolescents aged 13-16 years. The 1MRW was administered on an outside track and a laboratory VO2Peak test was conducted using a maximal treadmill protocol. Multiple linear regression was employed to develop the prediction model. Results yielded the following algorithm: VO2Peak = 7.34 × (1MRW speed in m s(-1)) + 0.23 × (age × sex) + 17.75. The New Model displayed a multiple correlation and prediction error of R = 0.81, standard error of the estimate = 4.78 ml kg(-1) · min(-1), with measured VO2Peak and good criterion-referenced (CR) agreement into FITNESSGRAM's Healthy Fitness Zone (Kappa = 0.62; percentage agreement = 84.4%; Φ = 0.62). The New Model was validated using k-fold cross-validation and showed homoscedastic residuals across the range of predicted scores. The omission of BMI did not compromise accuracy of the model. In conclusion, the New Model displayed good predictive accuracy and good CR agreement with measured VO2Peak in adolescents aged 13-16 years.
一种通过一英里跑/走测试（1MRW）预测最大摄氧量（VO2Peak）的常用算法包含体重指数（BMI），这在学校环境中存在实际问题。本研究的目的是开发一种独立于BMI的青少年1MRW有氧能力模型。收集了90名13 - 16岁青少年的心肺耐力数据。1MRW在室外跑道上进行，实验室VO2Peak测试采用最大跑步机方案。采用多元线性回归来开发预测模型。结果得出以下算法：VO2Peak = 7.34×（1MRW速度，单位：m s(-1)） + 0.23×（年龄×性别） + 17.75。新模型的多重相关系数和预测误差为R = 0.81，估计标准误差 = 4.78 ml kg(-1)·min(-1)，与实测VO2Peak具有良好的标准参照（CR）一致性，且与FITNESSGRAM的健康体适能区相符（卡帕系数 = 0.62；一致性百分比 = 84.4%；Φ系数 = 0.62）。新模型通过k折交叉验证进行了验证，在预测分数范围内显示出同方差残差。省略BMI并未影响模型的准确性。总之，新模型在13 - 16岁青少年中与实测VO2Peak相比显示出良好的预测准确性和良好的CR一致性。
