【摘要】众所周知，情感可以预测一般人群的较高体力活动 (PA) 水平，并且可以通过较高的体力活动 (PA) 水平得到增强。这项二次分析旨在加深对体重较高的成年人中PA与核心情感 (即效价、精力充沛的唤醒和平静) 之间的双向关系的理解。在自然环境中，通过生态瞬时评估对157名参与者 (体重指数：32.99±3.78 kg/m2) 的混合抽样方案进行情感和 PA 评估。多级模型表明，在评估前15分钟内进行更多的身体活动可以预测精力充沛的唤醒增加和平静度的降低。随后，感觉更有活力和更焦躁与接下来15分钟内的PA增加有关。效价 (即愉悦-不愉悦) 与PA无关，也不能预测后续的PA。数字PA干预措施可能旨在增强能量感，并就这些独特的心理益处提供心理教育。

[Abstract] Affect is known to be predictive of and enhanced by higher physical activity (PA) levels in the general population. This secondary analysis aimed to increase the understanding of the bi-directional relationship between PA and core affect (i.e. valence, energetic arousal, and calmness) among adults with higher body weight. Affect and PA were assessed in naturalistic settings via ecological momentary assessment using a mixed sampling scheme from 157 participants (body mass index: 32.99 ± 3.78 kg/m2). Multilevel models revealed that being more physically active in the 15 minutes prior to the assessment predicted an increase in energetic arousal and a decrease in calmness. Subsequently, feeling more energetic and agitated was associated with increased PA within the following 15 minutes. Valence (i.e. pleasure–displeasure) was not associated with PA nor predictive of subsequent PA. Digital PA interventions may target the enhancement of feelings of energy and present psychoeducation about these distinct psychological benefits.
