背景青少年的体力活动(PA)和能量消耗(EE)的评估由于儿童和青春期生长和成熟的内在变异性而变得复杂。本研究描述了7-13岁儿童不同活动类型的EE。方法对105名7-13岁儿童(男孩：57%，女孩：43%，年龄：9.9±1.9)进行了24项活动中的12项活动，并用间接量热法进行监测。结果体力活动中，VO_2ml·kg·min~(-1)、VO_2L·min~(-1)、EE和METS的平均值分别为3.3~53.7ml·kg·min~(-1)、0.15~3.2ml·min~(-1)、在0.7~15.9kcal·min-1之间，1.5~7.8 kcal·min-1。结论不同年龄、性别和BMI状态的活动的能量消耗不同，在检查青年PA的相对强度时，需要考虑调整的必要性。
BackgroundThe assessment of physical activity (PA) and energy expenditure (EE) in youth is complicated by inherent variability in growth and maturation during childhood and adolescence. This study provides descriptive summaries of the EE of a diverse range of activities in children ages 7 to 13.MethodsA sample of 105 7- to 13-year-old children (boys: 57%, girls: 43%, and Age: 9.9 ± 1.9) performed a series of 12 activities from a pool of 24 activities while being monitored with an indirect calorimetry system.ResultsAcross physical activities, averages of VO2ml·kg·min-1, VO2L·min-1, EE, and METs ranged from 3.3 to 53.7 ml·kg·min-1, from 0.15 to 3.2 L·min-1, from 0.7 to 15.9 kcal·min-1, 1.5 MET to 7.8 MET, respectively.ConclusionsThe energy costs of the activities varied by age, sex, and BMI status reinforcing the need to consider adjustments when examining the relative intensity of PA in youth.
