Euro积分了解青少年中度至剧烈体力活动（MVPA）和久坐行为的预测因子和后果。方法26名青少年（法师= 15.96，SD = 1.56）被试提供了80份主观状态自评报告和20天内连续的MVPA和久坐行为的客观报告。结果所有的情感和感觉变量预测MVPA的模型都观察到了随机效应。人内积极情感和久坐行为存在负固定效应，而消极情感则呈负相关。人内MVPA是积极情感和能量的显著正向预测因子。人内MVPA和疲劳存在随机效应。有一个显着的随机效应，人内久坐行为预测积极的影响。人内久坐行为是一个显着的负面预测能源。ConclusionsaEuro积分结果突出了主观状态和身体活动之间的关联的内在本质的重要性。
ObjectiveaEuro integral To understand the predictors and consequences of adolescent moderate-to-vigorous physical activity (MVPA) and sedentary behavior in nearly real-time. MethodsaEuro integral Participants were 26 adolescents (Mage = 15.96, SD = 1.56) who provided 80 self-reports of subjective states and continuous objective reports of MVPA and sedentary behavior over 20 days. ResultsaEuro integral Random effects were observed for all of the models with affect and feeling variables predicting MVPA. There was a negative fixed effect for within-person positive affect and sedentary behavior and the inverse association for negative affect. Within-person MVPA was a significant positive predictor of positive affect and energy. There was a random effect for within-person MVPA and fatigue. There was a significant random effect for within-person sedentary behavior predicting positive affect. Within-person sedentary behavior was a significant negative predictor of energy. ConclusionsaEuro integral Findings highlight the importance of the intrapersonal nature of the associations among subjective states and physical activity.
