A comparative evaluation of the ability of activity monitors to predict energy expenditure (EE) is necessary to aid in the investigation of the effect of EE on health. The purpose of this study was to validate and compare the RT3, the SWA and the IDEEA at measuring EE in adults and children. Twenty-six adults and 22 children completed a resting metabolic rate (RMR) test and performed four treadmill activities at 3 km.h(-1), 6 km.h(-1), 6 km.h(-1) at a 10% incline, 9 km.h(-1). EE was assessed throughout the protocol by the RT3, the SWA and the IDEEA. Indirect calorimetry (IC) was used as a criterion measure of EE against which each monitor was compared. Mean bias was assessed by subtracting EE from IC from EE from each monitor for each activity. Limit of agreement plots were used to assess the agreement between each monitor and IC. Limits of agreement for resting EE were narrowest for the RT3 for adults and children. Although the IDEEA displayed the smallest mean bias between measures at 3 km.h(-1), 6 km.h(-1) and 9 km.h(-1) in adults and children, the SWA agreed closest with IC at 6 km.h(-1), 6 km.h(-1) at a 10% incline and 9 km.h(-1). Limits of agreement were closest for the SWA at 9 km.h(-1) in adults representing 42% of the overall mean EE. Although the RT3 provided the best estimate of resting EE in adults and children, the SWA provided the most accurate estimate of EE across a range of physical activity intensities.
活动监测仪在预测能量消耗 (EE) 方面的能力比较评估对于研究 EE 对健康的影响是必要的。本研究的目的是验证和比较 RT3、SWA 和 IDEEA 在测量成年人和儿童 EE 方面的能力。26 名成年人和 22 名儿童完成了静息代谢率 (RMR) 测试，并以 3km.h(-1)、6km.h(-1)、6km.h(-1)的坡度为 10%、9km.h(-1)进行了四项跑步机活动。在整个方案中，RT3、SWA 和 IDEEA 评估了 EE。间接测热法 (IC) 作为 EE 的标准测量方法，与每个监测器进行比较。通过从每个活动中从 IC 中减去每个监测器的 EE 来评估平均偏差。使用界限协议图来评估每个监测器与 IC 之间的一致性。休息时 EE 的协议范围最窄的是成人和儿童的 RT3。尽管 IDEEA 在成年人和儿童的 3km.h(-1)、6km.h(-1)和 9km.h(-1)测量中显示出最小的平均偏差，但 SWA 在 6km.h(-1)、6km.h(-1)和 9km.h(-1)的坡度上与 IC 最接近。协议范围最接近 SWA 在成年人中的 9km.h(-1)，占总平均 EE 的 42%。尽管 RT3 为成年人和儿童提供了休息时 EE 的最佳估计值，但 SWA 在各种体力活动强度下提供了最准确的 EE 估计值。
