摘要：Benden M, Mancuso L, Zhao H, Pickens A. The Ability of theSenseWear® Armband to Assess a Change in Energy Expenditure inChildren While Sitting and Standing. JEPonline 2011;14(3):1-14.Increasing physical activity levels of children in school has become aprimary method of combating the growing trend of childhood obesity.As part of a large field trial that is currently seeking to evaluate theimpact of the stand-biased desk on children’s energy expenditure inschool, this study first evaluated the degree to which the SenseWear®Armband measures a change in energy expenditure in children whilesitting and standing at a desk in a controlled laboratory environment. Ifthe device is found sensitive enough to detect differences in thelaboratory, the research team plans to use it in the larger schoolstudy. This study was conducted with 21 children between 7 and 10yrs of age. The children wore the SenseWear® Armband while sittingat a traditional desk and while standing at a height-adjusted standingdesk with footrest for 30 min each. The mean energy expenditure forsitting was 0.63 kcal·min-1, ranging from 0.39-1.08. The mean energyexpenditure for standing was 0.71 kcal·min-1(range = 0.40 to 1.10).Paired comparisons indicated that the average energy expenditurewas significantly higher when the subjects were standing versussitting (P<0.0001). Therefore, we concluded that the SenseWear®Armband is sensitive enough to detect changes in energy expenditurein children 7 to 10 yrs of age while sitting and standing. The use ofthe SenseWear® Armband to assess slight changes in energyexpenditure in children is both practical and sensitive.
