在整理世界范围内的基础代谢率 (BMR) 测量值时，了解不同仪器之间的比较情况以及方法学错误是否会导致测量的 BMR 差异变得非常重要。使用五种不同仪器的不同组合测量了 34 名健康个体的 BMR。结果表明，oxylog 之间的能量输出相当。 Hartmann 和 Braun Metabolator、通风帐篷和头罩以及全身间接热量计：微小差异（如果有的话）不具有统计显着性。然而，当对不习惯该设备的受试者进行测量时，使用通风帐篷和头罩的受试者与热量计之间存在显着的相互作用。当将氧气消耗测量值转换为能量输出时，一些仪器做出的假设会在最终结果中引入可变误差，这可能会导致在编制人类基础代谢率大型数据库时出现系统误差。
While collating basal metabolic rate (BMR) measurements made worldwide it becomes important to know how different instruments compare with each other and whether errors in methodology could account for the differences in BMRs measured. BMRs of 34 healthy individuals were measured by using five different instruments in various combinations. Results show that energy outputs were comparable between the oxylog. Hartmann and Braun Metabolator, ventilated tent and hood, and whole-body indirect calorimeter: small differences, if any, were not statistically significant. However, significant interactions existed between subjects with the ventilated tent and hood and calorimeter when measurements were taken in subjects who were unaccustomed to the apparatus. When converting O2-consumption measurements to energy output, some instruments make assumptions that introduce a variable error in the final result, which may lead to systematic errors during the compilation of large databases of human BMRs.
