Few studies have investigated the short-term, momentary relationships between physical activity (PA) and well-being. This study focuses on investigating the dynamic relationships between PA and affective well-being among adults with type 1 diabetes. Participants (n = 122) wore an accelerometer and completed daily EMA surveys of current activities and affective states (e.g., happy, stressed, excited, anxious) via smartphone over 14 days. Within-person, increased sedentary time was associated with less positive affect (r = - 0.11, p < 0.001), while more PA of any intensity was associated with greater positive affect and reduced fatigue, three hours later. Between-person, increased light PA was associated with increased stress (r = 0.21, p = 0.02) and diabetes distress (r = 0.30, p = 0.001). This study provides evidence that positive affect and fatigue are predicted by previous activity regardless of the different activities that people engaged in. Positive affect increased after engaging in PA. However, participants with higher amounts of light PA reported higher stress ratings.
很少有研究调查过身体活动 (PA) 和幸福感之间的短期、瞬间关系。本研究专注于调查 1 型糖尿病成年人中 PA 与情感幸福感之间的动态关系。参与者（n=122）佩戴加速度计，并通过智能手机在 14 天内完成每日 EMA 调查，记录当前活动和情感状态（例如，快乐、压力大、兴奋、焦虑）。个体内，久坐时间的增加与积极情绪减少有关（r=-0.11，p<0.001），而任何强度的 PA 增加都与三小时后积极情绪增加和疲劳减少有关。个体间，轻度 PA 的增加与压力增加（r=0.21，p=0.02）和糖尿病困扰（r=0.30，p=0.001）有关。本研究提供的证据表明，积极情绪和疲劳是由先前的活动预测的，而与人们从事的不同活动无关。PA 后积极情绪增加。然而，进行更多轻度 PA 的参与者报告的压力评分更高。
