BACKGROUND/OBJECTIVE: Obtaining data on the energy expenditure of physical activity (PA) in children and adolescents with obesity is crucial for promoting health in this population through exercise. However, relevant research is limited. This study aimed to determine the energy expenditure characteristics of 37 diverse PAs in children and adolescents with obesity and examine the association between obesity and energy expenditure (EE) characteristics within this cohort.
Three hundred and ninety-seven children and adolescents with obesity aged 9-17 performed various PAs. PA intensity, EE, and body fat (BF) percentage were measured.
The resting oxygen uptake (VO) and resting energy expenditure (REE) of children and adolescents with obesity were 4.23 (3.72-4.84) ml/kg/min and 0.020 (0.018-0.023) kcal/kg/min, respectively, with significant differences between boys and girls ( < 0.05). The metabolic equivalent of task (MET) values for the PAs ranged from 1.12 to 8.14 METs. Regression analyses revealed an inverse association with age, BMI, and percentage BF increased, with resting VO, REE, and average PA energy expenditure (PAEE) during PAs.
(1) Resting VO was lower in children and adolescents with obesity than those with normal weight and higher than in adults. (2) Of the measured PA intensities, 8 were light, 17 were moderate, and 5 were vigorous intensity. (3) The increase in the degree of obesity and age further decreased VO and EE both at rest and during PA. Our results can provide precise guidance for the exercise of children and adolescents with obesity and serve as a reference for the development of physical activity guidelines and compendiums. Future research should further diversify the types of PAs measured.
背景/目的：获取肥胖儿童和青少年体力活动（PA）能量消耗数据对于通过运动促进该人群健康至关重要。然而，相关研究有限。本研究旨在确定肥胖儿童和青少年 37 种不同 PA 的能量消耗特征，并探讨该队列中肥胖与能量消耗（EE）特征之间的关系。
397 名 9-17 岁肥胖儿童和青少年进行了各种 PA。测量 PA 强度、EE 和体脂（BF）百分比。
肥胖儿童和青少年的静息摄氧量（VO）和静息能量消耗（REE）分别为 4.23（3.72-4.84）ml/kg/min 和 0.020（0.018-0.023）kcal/kg/min，男孩和女孩之间存在显著差异（<0.05）。PA 的代谢当量（MET）值范围为 1.12 至 8.14 METs。回归分析显示，随着年龄、BMI 和 BF 百分比的增加，与静息 VO、REE 和 PA 期间平均 PAEE 呈负相关。
（1）肥胖儿童和青少年的静息 VO 低于体重正常者，高于成年人。（2）在所测量的 PA 强度中，8 种为轻度，17 种为中度，5 种为剧烈强度。（3）肥胖程度和年龄的增加进一步降低了休息和 PA 期间的 VO 和 EE。我们的研究结果可以为肥胖儿童和青少年的运动提供精确的指导，并为体力活动指南和纲要的制定提供参考。未来的研究应进一步多样化所测量的 PA 类型。
