Affective judgments are one of the strongest predictors of physical activity. Engaging in body surveillance during physical activity is theorized to reduce access to pleasant affective experiences thereby compromising the influence of affective judgments. However, empirical tests of this relationship are lacking. This study examined associations between body surveillance during physical activity and affective judgments (i.e., enjoyment and pleasure) of physical activity. Participants (N = 89; 53 % women, M_age = 20.32 years; SD_age = 1.59) completed an experience sampling protocol for 7 days and provided 7 self-reports/day. Participants reported their body surveillance when engaged in physical activity followed by their affective judgments of physical activity. At the within-person level, participants reported more negative affective judgments during instances when body surveillance was higher than usual. At the between-person level, participants higher in body surveillance reported more negative affective judgments on average. These findings extend correlates of body surveillance to include less favorable affective judgments. Although there is support for targeting affective judgments to promote physical activity, the utility of such efforts may be limited if body surveillance is present. These findings point to a new target for potentially enhancing affective judgements and the promotion of physical activity.

情感判断是体育锻炼的最强预测指标之一。从理论上讲，在体育锻炼期间进行身体监视可以减少获得愉悦情感体验的机会，从而损害情感判断的影响。但是，缺乏这种关系的实证检验。这项研究检查了体育锻炼期间身体监测与体育锻炼的情感判断（即享受和愉悦）之间的关联。参与者（N = 89； 53％的女性，M_年龄= 20.32岁；SD_年龄= 1.59）完成了7天的体验抽样协议，并提供了7份自报告/每天。参与者报告了进行体育锻炼后的身体监测，随后进行了对体育锻炼的情感判断。在人内层面，参与者报告说，在身体监视程度高于平常的情况下，负面的情感判断更多。在人与人之间，身体监测较高的参与者平均而言报告的负面情感判断更多。这些发现扩展了身体监测的相关性，以包括不利的情感判断。尽管支持以情感判断为目标来促进体育锻炼，但如果存在身体监视，则这种努力的效用可能会受到限制。
