At least 60 min of daily physical activity (PA) are recommended for weight control, a target achieved by only 3% of obese (OB) women. The purposes of this study were to examine (i) the affective responses of normal-weight (NW), overweight (OW), and OB middle-aged sedentary women to exercise of increasing intensity and (ii) the relationship of affective responses to self-efficacy and social physique anxiety. The women participated in a graded treadmill protocol to volitional exhaustion while providing ratings of pleasure-displeasure and perceived activation each minute. The Activation Deactivation Adjective Check List (AD ACL) was also completed before and after exercise. The affective responses of NW and OW women did not differ. However OB women gave lower pleasure ratings during the incremental protocol and reported lower Energy scores immediately after the protocol. Social physique anxiety, but not self-efficacy, was inversely related to pleasure and energy. The lower levels of pleasure and energy experienced by OB than nonobese women could account in part for their dramatically low levels of PA participation. Modifying the cognitive antecedents of social physique anxiety might be a useful intervention strategy.
每天至少 60 分钟的身体活动（PA）被推荐用于控制体重，但只有 3%的肥胖（OB）女性能够达到这一目标。本研究的目的是探讨（i）正常体重（NW）、超重（OW）和 OB 中年久坐女性对不同强度运动的情感反应，以及（ii）情感反应与自我效能感和社交身体焦虑的关系。女性参与了一个递增跑步机方案，直到达到自愿衰竭，并在每分钟提供愉悦-不愉悦和感知激活的评分。在运动前后还完成了激活去激活形容词检查表（AD ACL）。NW 和 OW 女性的情感反应没有差异。然而，OB 女性在递增方案中给予的愉悦评分较低，并且在方案结束后立即报告的能量评分较低。社交身体焦虑，但不是自我效能感，与愉悦和能量呈负相关。与非肥胖女性相比，OB 女性体验到的愉悦和能量水平较低，这可能部分解释了她们极低的 PA 参与水平。改变社交身体焦虑的认知前因可能是一种有效的干预策略。
