There is limited research on how the context in which moderate-to-vigorous physical activity (MVPA) occurs influences the relationship between physical activity and affect. This study aimed to investigate how the social context and physical environment enhance the relationship between MVPA and affect in daily life. Overall, 119 adolescents (mean age = 14.7 years) provided information about their core affect, physical environment and social context on multiple occasions over a 4-day period using ecological momentary assessment. Additionally, participants’ level of MVPA was objectively measured using accelerometers. Level of MVPA was positively associated with energetic arousal, being outdoors was positively associated with valence and energetic arousal, and being with someone else was also positively associated with energetic arousal. Additionally, being outdoors moderated the association between MVPA and tense arousal so that MVPA was only inversely related to tense arousal when outdoors. These findings showed that young people experience more positive valence, greater levels of energetic arousal and less tense arousal when physically active outdoors compared to when indoors and highlight the importance of encouraging young people to participate in physical activity outdoors. Further research is warranted to understand how social contexts may influence the association between MVPA and affect in young people.

关于中度至剧烈体育锻炼（MVPA）发生的背景如何影响体育锻炼与影响之间的关系的研究很少。这项研究旨在调查社会背景和自然环境如何增强MVPA与日常生活之间的关系。总共有119名青少年（平均年龄= 14.7岁）使用生态瞬时评估在4天的时间内多次提供了有关其核心情感，身体环境和社会背景的信息。此外，使用加速度计客观地测量了参与者的MVPA水平。MVPA的水平与精力充沛的唤醒呈正相关，在户外与价和精力充沛的唤醒呈正相关，与其他人在一起也与精力充沛的唤醒呈正相关。另外，在户外时，可以缓解MVPA和时态唤醒之间的关联，因此在户外时，MVPA与时态唤醒仅呈负相关。这些发现表明，与室内运动相比，年轻人在室外进​​行体育锻炼时具有更高的正价，更高的精力旺盛觉醒和较少的紧张觉醒，并强调了鼓励年轻人在户外进行体育锻炼的重要性。有必要进行进一步的研究，以了解社会环境如何影响MVPA之间的关联以及对年轻人的影响。与在室内进行体育活动相比，在户外进行体育活动时，精力充沛的唤醒水平较高，而紧张的唤醒程度较低，这凸显了鼓励年轻人在户外进行体育锻炼的重要性。有必要进行进一步的研究，以了解社会环境如何影响MVPA之间的关联以及对年轻人的影响。与在室内进行体育活动相比，在户外进行体育活动时，精力充沛的唤醒水平较高，而紧张的唤醒程度较低，这凸显了鼓励年轻人在户外进行体育锻炼的重要性。有必要进行进一步的研究，以了解社会环境如何影响MVPA之间的关联以及对年轻人的影响。
