目的：大多数关于儿童情感和身体感觉状态与身体活动相互作用的研究是在实验室条件下进行的，未能捕捉个体内的协变。当前研究使用生态瞬时评估（EMA）双向检验情感和身体感觉状态如何与儿童日常生活中自然环境下客观测量的身体活动相关。方法：儿童（N = 119，年龄9 - 13岁，52%为男性，32%为西班牙裔）完成了8天的EMA监测，每天最多7次测量积极情感（PA）、消极情感（NA）、疲倦感和精力充沛感。EMA反应与每次EMA调查前后30分钟内加速度计评估的中等到剧烈身体活动（MVPA）进行时间匹配。结果：在EMA提示后的30分钟内，精力充沛感评分较高和疲倦感评分较低与更多的MVPA相关。在EMA提示前30分钟内更多的MVPA与更高的PA评分、精力充沛感以及更低的NA评分相关。个体间分析表明，平均每小时休闲时间的MVPA与PA和NA的个体内变异性较小相关。结论：身体感觉状态可预测儿童随后的身体活动水平，而身体活动水平反过来又可预测儿童随后的情感状态。活跃的儿童表现出更高的积极和消极情绪稳定性。尽管这些关联的强度适中，其临床相关性尚不明确，但了解身体活动的前因和后果可能对儿童身体活动的维持和促进以及心理健康具有理论和实践意义。
Objective: Most research on the interplay of affective and physical feelings states with physical activity in children has been conducted under laboratory conditions and fails to capture intraindividual covariation. The current study used Ecological Momentary Assessment (EMA) to bidirectionally examine how affective and physical feeling states are related to objectively measured physical activity taking place in naturalistic settings during the course of children's everyday lives. Methods: Children (N = 119, ages 9-13 years, 52% male, 32% Hispanic) completed 8 days of EMA monitoring, which measured positive affect (PA), negative affect (NA), feeling tired, and feeling energetic up to 7 times per day. EMA responses were time-matched to accelerometer assessed moderate-to-vigorous physical activity (MVPA) in the 30 min before and after each EMA survey. Results: Higher ratings of feeling energetic and lower ratings of feeling tired were associated with more MVPA in the 30 min after the EMA prompt. More MVPA in the 30 min before the EMA prompt was associated with higher ratings of PA and feeling energetic and lower ratings of NA. Between-subjects analyses indicated that mean hourly leisure-time MVPA was associated with less intraindividual variability in PA and NA. Conclusions: Physical feeling states predict subsequent physical activity levels, which in turn, predict subsequent affective states in children. Active children demonstrated higher positive and negative emotional stability. Although the strength of these associations were of modest magnitude and their clinical relevance is unclear, understanding the antecedents to and consequences of physical activity may have theoretical and practical implications for the maintenance and promotion of physical activity and psychological well-being in children.
