The SenseWear Pro2 Armband (SWA; BodyMedia, Inc., Pittsburg, PA), the Intelligent Device for Energy Expenditure and Activity (IDEEA; Minisun LLC, Fresno, CA), and the ActiReg (AR; PreMed AS, Oslo, Norway) were compared with indirect calorimetry to determine the ability of these devices to assess energy cost in children during resting and different physical activities.
Fourteen children, 11-13 yr old, wore the SWA, the IDEEA, and the AR during resting, sitting, stationary bicycling, jumping on a trampoline, playing basketball, stair walking, and walking/running along a 50-m track. The Oxycon Mobile portable metabolic system (VIASYS Healthcare, Conshohocken, PA) was used as the criterion method for energy cost.
For resting and sitting, the three activity monitors showed comparable results, but none of them accurately assessed energy cost for stationary bicycling, jumping on a trampoline, or playing basketball. The IDEEA was the only activity monitor that accurately assessed energy cost for stair walking. Also, the IDEEA showed a close estimate of energy cost across the walking and the running intensities, whereas the SWA accurately assessed energy cost for slow to normal walking but showed increased underestimation of energy cost with increasing speed. The AR overestimated energy cost during walking and during slow running but did not respond to increasing running speed.
To be able to capture children's physical activity, all three activity monitors need to be further developed. Overall, the IDEEA showed the highest ability to assess energy cost in this study, but SWA may be more feasible for use in children under free-living conditions.
将SenseWear Pro2臂带（SWA；BodyMedia公司，宾夕法尼亚州匹兹堡）、能量消耗与活动智能设备（IDEEA；Minisun有限责任公司，加利福尼亚州弗雷斯诺）和ActiReg（AR；挪威奥斯陆PreMed公司）与间接量热法进行比较，以确定这些设备评估儿童在休息和不同体育活动期间能量消耗的能力。
14名11至13岁的儿童在休息、坐着、固定自行车运动、在蹦床上跳跃、打篮球、走楼梯以及沿50米跑道行走/跑步时佩戴SWA、IDEA和AR。采用Oxycon Mobile便携式代谢系统（VIASYS Healthcare公司，宾夕法尼亚州康舍霍肯）作为能量消耗的标准测量方法。
在休息和坐着时，三种活动监测仪显示出可比的结果，但它们均未准确评估固定自行车运动、在蹦床上跳跃或打篮球时的能量消耗。IDEEA是唯一能准确评估走楼梯时能量消耗的活动监测仪。此外，IDEEA对行走和跑步强度下的能量消耗估计相近，而SWA能准确评估慢速至正常行走时的能量消耗，但随着速度增加，对能量消耗的低估程度增大。AR在行走和慢跑时高估了能量消耗，但对跑步速度增加无反应。
为了能够记录儿童的身体活动，所有三种活动监测仪都需要进一步改进。总体而言，在本研究中IDEEA显示出评估能量消耗的最高能力，但SWA在自由生活条件下用于儿童可能更可行。
