Affective response during physical activity may influence motivation to perform future physical activity behavior. However, affective response during physical activity is often assessed under controlled laboratory conditions. The current study used ecological momentary assessment (EMA) to capture affective responses during free-living physical activity performed by adults, and determined whether these affective responses predict future moderate-to-vigorous physical activity (MVPA) levels after 6 and 12 months.
At baseline, electronic EMA surveys were randomly prompted across 4 days asking about current activities and affective states (e.g., happy, stressed, energetic, tired). Affective response during physical activity was operationalized as the level of positive or negative affect reported when concurrent physical activity (e.g., exercise or sports) was also reported. Data were available for 82 adults. Future levels of moderate-to-vigorous physical activity (MVPA) were measured using accelerometers, worn for seven consecutive days at 6 and 12 months after the baseline assessment.
Feeling more energetic during physical activity was associated with performing more minutes of daily MVPA after both 6 and 12 months. Feeling less negative affect during physical activity was associated with engaging in more daily MVPA minutes after 12 months only.
This study demonstrated how EMA can be used to capture affective responses during free-living physical activity. Results found that feelings more energetic and less negative during physical activity were associated with more future physical activity, suggesting that positive emotional benefits may reinforce behavior.
体育活动中的情感反应可能会影响未来进行体育活动行为的动机。然而，体育活动中的情感反应通常是在受控的实验室条件下进行评估的。本研究采用生态瞬时评估（EMA）来捕捉成年人在自由生活体育活动中的情感反应，并确定这些情感反应是否能预测6个月和12个月后未来的中度至剧烈体育活动（MVPA）水平。
在基线时，电子EMA调查在4天内随机提示，询问当前的活动和情感状态（如快乐、压力大、精力充沛、疲惫）。体育活动中的情感反应被定义为报告同时进行体育活动（如锻炼或运动）时所报告的积极或消极情感水平。共有82名成年人的数据可用。未来的中度至剧烈体育活动（MVPA）水平使用加速度计进行测量，在基线评估后的6个月和12个月连续佩戴7天。
在6个月和12个月后，体育活动中感觉更精力充沛与每天进行更多分钟的MVPA有关。仅在12个月后，体育活动中感觉消极情绪较少与每天进行更多分钟的MVPA有关。
本研究展示了EMA如何用于捕捉自由生活体育活动中的情感反应。结果发现，体育活动中感觉更精力充沛和消极情绪较少与未来更多的体育活动有关，这表明积极的情感益处可能会强化行为。
