This study developed a formula for calculating the predicted VO₂ max value using a prototype model of foot-based cardiorespiratory exercise. Forty sedentary workers (20 men and 20 women) were enrolled via consecutive sampling. They underwent direct measurement of VO₂ max using spiroergometry as the gold standard; the predicted VO₂ max value was calculated using a prototype model of foot-based cardiorespiratory exercise, which was performed on consecutive days. Multivariate linear regression analysis was used to formulate the equation for the predicted VO₂ max value by including potential contributing variables: gender, body height, body weight and heart rate. Bland–Altman test was used for assessing the agreement level for the predicted VO₂ max value. The equation for the predicted VO₂ max value was formulated as 3.2 + 0.15 optimal exercise heart rate −5.5 sexes (0 for men, 1 for women). The agreement level for the formula was acceptable in all measurement result ranges. The formula developed in this study can be used to measure the predicted VO₂ max value with an acceptable agreement level.

本研究开发了一个公式，用于使用基于足部的心肺运动原型模型来计算预测的 VO _{2最大值。}通过连续抽样招募了 40 名久坐工人（20 名男性和 20 名女性）。他们使用螺旋测功法作为金标准直接测量 VO _{2 max；}预测的 VO ₂最大值是使用连续几天进行的足部心肺运动原型模型计算的。使用多元线性回归分析通过包括潜在影响变量：性别、身高、体重和心率来制定预测VO _{2最大值的方程。}Bland-Altman 检验用于评估预测 VO ₂最大值的一致性水平。_{预测VO 2}最大值的方程被公式化为3.2 + 0.15 最佳运动心率-5.5 性别（0 为男性，1 为女性）。公式的一致性水平在所有测量结果范围内都是可接受的。本研究中开发的公式可用于测量预测的 VO ₂最大值，且具有可接受的一致性水平。
