A mew approach for estimating metabolic rates for manual materials handling jobs is presented. This approach was applied to 48 different jobs. The model validation showed a correlation coefficient of 0.95 between the measured and predicted metabolic rates. The coefficient of variation (standard error/sample mean) was 10.2 percent.
提出了一种估算人工物料搬运工作代谢率的新方法。该方法应用于48种不同的工作。模型验证表明，实测代谢率与预测代谢率之间的相关系数为0.95。变异系数（标准误差/样本均值）为10.2%。
