【摘要】缺乏身體活動是一個緊迫的社會問題。要充分發揮身體活動（PA）作為關鍵健康資源的潛力，必須理解參與身體活動的機制。實驗室研究和干預研究已證實運動與情感幸福感（AWB）相關，並提示AWB可能影響身體活動行為。數字化技術使得研究日常生活中的身體活動與AWB之間的關係成為可能，但既往單項研究的結論尚不明確。本研究匯總了截至2023年12月的67個數據集（占符合條件記錄的55.2%），涵蓋了321,345次基於智能手機的AWB評分和近100萬小時由加速度計測量的身體活動數據（參與者總數N=8,223），旨在闡明身體活動與AWB之間關聯的性質與程度。基於個體參與者數據的一階段和兩階段薈萃分析顯示，日常生活中的瞬時AWB與先前的身體活動（個體內部：r=0.05，99.2%置信區間[CI] 0.03–0.06；個體之間：r=0.08，99.2% CI 0.04–0.12）及隨後的身體活動（個體內部：r=0.04，99.2% CI 0.03–0.05；個體之間：r=0.08，99.2% CI 0.04–0.13）均存在關聯。在個體內部，身體活動與精力充沛的喚醒狀態（energetic arousal）、積極情感狀態及情感效價（valence）呈正相關，而與平靜感呈負相關。其實際效應量與其他日常生活活動相當，其中精力充沛的喚醒狀態與身體活動的關聯最為顯著。個體間關聯存在的顯著異質性，可部分由社會人口學調節變量來解釋。在個體之間，身體活動與積極情感狀態相關。這些結果證實了身體活動與情感幸福感之間的關係在日常生活中的重要意義。它們有助於健康行為模型的修訂與發展，並為探究身體活動（PA）與情感幸福感（AWB）之間關聯背後的行為、生理及神經機制提供了一個切入點。

[Abstract] Physical inactivity constitutes a pressing societal problem. To realize physical activity’s (PA) potential as a key health resource, mechanisms of PA engagement need to be understood. Laboratory and interventional studies documented that exercise relates to affective well-being (AWB) and suggested that AWB may shape PA behaviour. Digitalization enabled the investigation of how PA relates to AWB in everyday life, but findings from individual studies are ambiguous. Here we compiled 67 datasets (55.2% of eligible records) including 321,345 smartphone-based AWB ratings and nearly 1,000,000 h of accelerometer-measured PA (N = 8,223 participants) until December 2023 to clarify the nature and extent of PA–AWB associations. One- and two-stage individual participant data meta-analyses reveal that momentary AWB is associated with both prior (within, r = 0.05, 99.2% confidence intervals (CI) 0.03 to 0.06; between, r = 0.08, 99.2% CI 0.04 to 0.12) and subsequent (within, r = 0.04, 99.2% CI 0.03 to 0.05; between, r = 0.08, 99.2% CI 0.04 to 0.13) short-term PA in everyday life. Within persons, PA displays a positive association with energetic arousal, positive affective states and valence, yet a negative relation to calmness. The practical effect sizes are comparable to other daily life activities, with energetic arousal evincing the strongest relation to PA. Considerable heterogeneity in associations across individuals can be partially explained by sociodemographic moderators. Between participants, PA relates to positive affective states. The results document the critical relevance of PA–AWB relations in everyday life. They can contribute to the revision and development of health behaviour models and establish a starting point to approach behavioural, physiological and neuronal mechanisms underlying PA–AWB associations.
