Affect may be important for understanding physical activity behavior.
To examine whether affective valence (i.e., good/bad feelings) during and immediately following a brief walk predicts concurrent and future physical activity.
At months 6 and 12 of a 12-month physical activity promotion trial, healthy low-active adults (N=146) reported affective valence during and immediately following a 10-min treadmill walk. Dependent variables were self-reported minutes/week of lifestyle physical activity at months 6 and 12.
Affect reported during the treadmill walk was cross-sectionally (month 6: β=28.6, p=0.008; month 12: β=26.6, p=0.021) and longitudinally (β=14.8, p=0.030) associated with minutes/week of physical activity. Affect reported during a 2-min cool down was cross-sectionally (month 6: β=21.1, p=0.034; month 12: β=30.3, p<0.001), but not longitudinally associated with minutes/week of physical activity. Affect reported during a postcool-down seated rest was not associated with physical activity.
During-behavior affect is predictive of concurrent and future physical activity behavior.
情感可能对理解身体活动行为很重要。
检验在短暂步行过程中和之后的情感效价（即感觉良好/不好）是否能预测当前和未来的身体活动。
在一项为期 12 个月的身体活动促进试验的第 6 个月和第 12 个月，健康的低活跃成年人（N=146）报告了在 10 分钟跑步机步行过程中和之后的情感效价。因变量为第 6 个月和第 12 个月的生活方式身体活动的自我报告分钟/周。
在跑步机行走过程中报告的情感在横截面上（第 6 个月：β=28.6，p=0.008；第 12 个月：β=26.6，p=0.021）和纵向（β=14.8，p=0.030）与身体活动的分钟/周相关。在 2 分钟冷却期间报告的情感在横截面上（第 6 个月：β=21.1，p=0.034；第 12 个月：β=30.3，p<0.001），但与身体活动的分钟/周没有纵向关联。在冷却后坐姿休息期间报告的情感与身体活动无关。
行为中的情感是当前和未来身体活动行为的预测指标。
