目的：我们进行了一项研究，以确定三轴加速度计在不同运动速度下的最佳佩戴位置。材料和方法：我们对 66 名健康韩国成年人（26 名男性和 40 名女性）进行了一项观察性研究。运动前的静息代谢率 (RMR)、体力活动相关能量消耗 (PARE) 通过心肺气体分析仪和信号矢量幅度 (SVM) 进行测量，同时在四个不同部位（手腕、腰部、上臂和脚踝）佩戴四个三轴加速度计，运动速度为 2-10 km/h。结果：平均 RMR 为 4.03 mL/kg/min，实际 MET（不同运动速度下的耗氧量除以个体 RMR）与计算的 MET（耗氧量除以 3.5 mL/kg/min）相比显示出相对较低的值。当加速度计以低运动速度戴在手腕上时，PAEE 和 SVM 之间的总体相关性最高（r=0.751，p
Purpose: We performed a study to determine the best appropriate wearing site of a triaxial accelerometer at different exercise speeds. Materials and Methods: We conducted an observational study with 66 healthy Korean adults (26 men and 40-women). Resting metabolic rate (RMR) before exercise, physical activity-related energy expenditure (PARE) by cardiorespiratory gas analyzer and Signal Vector Magnitude (SVM) were measured while wearing four triaxial accelerometers on four different sites (wrist, waist, upper arm, and ankle) at exercise speeds from 2-10 km/h. Results: The mean RMR was 4.03 mL/kg/min and Actual METs (oxygen consumption at different exercise speeds divided by individual RMR) compared with the calculated METs (oxygen consumption divided by 3.5 mL/kg/min) showed relatively low value. The overall correlation between PAEE and SVM was highest when the accelerometer was worn on the wrist at low exercise speed (r=0.751, p
