This study aims to investigate the potential relationship between energy expenditure, physical fitness level, physical activity, and body mass index among children taking part in a 30 min school recess. A total of 259 participants from three schools were included in this study. Data on energy expenditure during recess, age, gender, anthropometric measurements, global physical fitness, and physical activity index were recorded. The evaluation sessions occurred twice a week on alternate days over two weeks. A significant gender difference was observed in energy expenditure during recess, favoring boys ( < 0.01). The participants classified as very active exhibited significantly higher scores compared to those categorized as sedentary and moderately active, respectively ( < 0.01), with a poor but significant correlation (rho: 0.208; < 0.001). There were significant differences between energy expenditure and cardiorespiratory fitness and energy expenditure and global physical fitness ( < 0.01) with fair (rho: 0.289; < 0.001) and poor (rho: 0.196, = 0.001) correlation, respectively. In contrast, there were no significant differences by body mass index categories ( = 0.571). These results suggest that gender, physical activity index, and global physical fitness were found to influence energy expenditure during a 30 min recess. However, no significant relationships were found with the body mass index.
本研究旨在调查参加30分钟学校课间休息的儿童的能量消耗、体能水平、身体活动与体重指数之间的潜在关系。本研究共纳入了来自三所学校的259名参与者。记录了课间休息期间的能量消耗、年龄、性别、人体测量数据、整体体能和身体活动指数。评估在两周内每周进行两次，隔天进行。课间休息期间的能量消耗存在显著的性别差异，男孩更占优势（<0.01）。与分别被归类为久坐和中度活跃的参与者相比，被归类为非常活跃的参与者表现出显著更高的分数（<0.01），且存在较弱但显著的相关性（rho：0.208；<0.001）。能量消耗与心肺适能以及能量消耗与整体体能之间存在显著差异（<0.01），相关性分别为中等（rho：0.289；<0.001）和较弱（rho：0.196，=0.001）。相比之下，体重指数类别之间没有显著差异（=0.571）。这些结果表明，性别、身体活动指数和整体体能被发现会影响30分钟课间休息期间的能量消耗。然而，未发现与体重指数有显著关系。
