To examine the validity of SenseWear Pro2 Armband in assessing energy cost of physical activities in children, and to contribute with values of energy costs in an overview of physical activities in children.
Energy cost was assessed by SenseWear Pro2 Armband in 20 healthy children, 11-13 yr, while lying down resting, sitting playing games on mobile phone, stepping up and down on a step board, bicycling on a stationary bike, jumping on a trampoline, playing basketball, and walking/running on a treadmill at the speeds 2, 3, 4, 5, 6, 7, 8, and 10 km x h(-1). During these activities, energy cost was also assessed from VO2 and VCO2 measured by Oxycon Mobile portable metabolic system, which was used as criterion method.
The difference in energy cost between SenseWear Pro2 Armband and Oxycon Mobile was -0.7 (0.5) (P < 0.001) for resting, -2.0 (0.9) (P < 0.001) for playing games on mobile phone, -6.6 (2.3) (P < 0.001) for stepping on the step board, -12.0 (3.7) (P < 0.001) for bicycling, -2.7 (11.9) (P = 0.34) for jumping on the trampoline, and -14.8 (6.4) kJ x min(-1) (P < 0.001) for playing basketball. The difference in energy cost between SenseWear Pro2 Armband and Oxycon Mobile for increasing treadmill speed was 1.3 (3.1) (P = 0.048), 0.1 (2.9) (P = 0.82), -1.2 (2.6) (P = 0.049), -1.6 (3.2) (P = 0.044), -3.1 (3.7) (P = 0.0013), -4.9 (3.7) (P < 0.001), -5.3 (3.7) (P < 0.001), and -11.1 (3.5) kJ x min(-1) (P < 0.001).
SenseWear Pro2 Armband underestimated energy cost of most activities in this study, an underestimation that increased with increased physical activity intensity. A table of energy costs (MET values) of physical activities in children measured by indirect calorimetry is presented as an initiation of the creation of a compendium of physical activities in children.
检验SenseWear Pro2臂带在评估儿童身体活动能量消耗方面的有效性，并为儿童身体活动概述中的能量消耗值提供数据。
使用SenseWear Pro2臂带对20名11 - 13岁的健康儿童在躺卧休息、坐着玩手机游戏、在踏板上上下踩踏、在固定自行车上骑行、在蹦床上跳跃、打篮球以及在跑步机上以2、3、4、5、6、7、8和10 km/h的速度行走/跑步时的能量消耗进行评估。在这些活动期间，还通过Oxycon Mobile便携式代谢系统测量的VO2和VCO2来评估能量消耗，该系统用作标准方法。
SenseWear Pro2臂带与Oxycon Mobile在能量消耗上的差异，休息时为 -0.7(0.5)（P < 0.001），玩手机游戏时为 -2.0(0.9)（P < 0.001），在踏板上踩踏时为 -6.6(2.3)（P < 0.001），骑自行车时为 -12.0(3.7)（P < 0.001），在蹦床上跳跃时为 -2.7(11.9)（P = 0.34），打篮球时为 -14.8(6.4) kJ/min（P < 0.001）。SenseWear Pro2臂带与Oxycon Mobile在跑步机速度增加时的能量消耗差异为1.3(3.1)（P = 0.048），0.1(2.9)（P = 0.82）， -1.2(2.6)（P = 0.049）， -1.6(3.2)（P = 0.044）， -3.1(3.7)（P = 0.0013）， -4.9(3.7)（P < 0.001）， -5.3(3.7)（P < 0.001），以及 -11.1(3.5) kJ/min（P < 0.001）。
在本研究中，SenseWear Pro2臂带低估了大多数活动的能量消耗，且这种低估随着身体活动强度的增加而增大。给出了通过间接测热法测量的儿童身体活动能量消耗（代谢当量值）表，作为创建儿童身体活动简编的开端。
