Abstract

Controversy exists in the literature as to the accuracy of the formulae used in predicting oxygen consumption (VO2) during level walking. The purpose of this study was to develop an equation for use at speeds of 54-130 m min-1. The VO2 and energy expenditure (EE) of 25 healthy subjects were measured while walking on a level, motor-driven treadmill at four varying speeds (54, 81, 107 and 130 m min-1). The regression analyses revealed that a quadratic model was a better predictor (p less than 0.05) of both the VO2 and EE than a linear model. The quadratic equation relating VO2 and EE to walking speed (X) is as follows: VO2 (ml kg-1 min-1) = 17.77 - 0.3023X(m min-1) + 0.0027X2 (R2 = 0.935, SEE = 1.5) EE (kcal min-1) = 6.14 - 0.1076X (m min-1) + 0.00093X2 (R2 = 0.830, SEE = 0.89).

摘要

关于预测平地行走时氧气消耗量（VO₂）所使用公式的准确性，文献中存在争议。本研究的目的是开发一个适用于速度为54 - 130米/分钟的方程。在水平电动跑步机上以四种不同速度（54、81、107和130米/分钟）行走时，测量了25名健康受试者的VO₂和能量消耗（EE）。回归分析表明，对于VO₂和EE，二次模型比线性模型是更好的预测指标（p小于0.05）。将VO₂和EE与行走速度（X）相关联的二次方程如下：VO₂（毫升/千克·分钟）= 17.77 - 0.3023X（米/分钟）+ 0.0027X²（R² = 0.935，标准误 = 1.5）；EE（千卡/分钟）= 6.14 - 0.1076X（米/分钟）+ 0.00093X²（R² = 0.830，标准误 = 0.89）。
