本研究开发了通过活动监测器预测儿童（n = 24）和成人（n = 24）活动能量消耗（AEE）的算法。每个参与者进行10项活动（仰卧休息，三次坐着，三次打扫房屋和三次运动），同时在脚踝，臀部和手腕上佩戴监测器; AEE根据耗氧量计算。使用回归分析。建立基于Actical（R）输出的AEE预测方程，对于儿童（R-2 = 45-75; p <0.001）和成人（R-2 = 0.001）两者变化相当大。14-85; p < .008）。大多数得到的算法准确地预测了累积的AEE和时间内轻，中度和剧烈的强度类别（p >。05）。Actical（R）监视器可用于预测踝关节、髋关节或腕关节位置的AEE和时间变量。
This study developed algorithms for predicting activity energy expenditure (AEE) in children (n = 24) and adults (n = 24) from the Actical (R) activity monitor. Each participant performed 10 activities (supine resting, three sitting, three house cleaning, and three locomotion) while wearing monitors on the ankle, hip, and wrist; AEE was computed from oxygen consumption. Regression analysis, used. to create AEE prediction equations based on Actical (R) output, varied considerably for both children (R-2 = 45-75; p < .001) and adults (R-2 =. 14-85; p < .008). Most of the resulting algorithms accurately predicted accumulated AEE and time within light, moderate, and vigorous intensity categories (p > . 05). The Actical (R) monitor may be useful for predicting AEE and time variables at the ankle, hip, or wrist locations.
