Unhealthy exercise is a core symptom of eating disorders that predicts greater chronicity and risk of relapse. A detailed conceptualization of unhealthy exercise in the context of eating disorders is only beginning to emerge, and associations between specific dimensions of unhealthy exercise and eating disorder symptoms have received little attention. The aim of the current study was to examine associations between three key dimensions of unhealthy exercise – compulsive exercise (i.e., rule-driven exercise to avoid negative affect), exercise to control weight/shape, and exercise to compensate for recent food intake – with restrictive eating and binge eating. Participants were 239 women drawn from two separate studies of emotions and eating behavior; 126 (52.7%) endorsed restrictive eating and/or objective binge eating episodes in the past three months. Unhealthy exercise dimensions were measured using the Compulsive Exercise Test and investigator-designed items, and eating disorder symptoms were assessed using the Eating Pathology Symptoms Inventory. Restrictive eating was only associated with avoidance and rule-driven exercise, whereas binge eating was significantly correlated with all unhealthy exercise variables. Multiple regression results revealed that only compensatory exercise was uniquely associated with binge eating. Unhealthy exercise consists of partially distinct dimensions with differential relations to core eating disorder symptoms. Future research should examine unhealthy exercise dimensions in patients with eating disorder diagnoses and consider whether treatments for specific unhealthy exercise forms might be beneficial.

不健康的运动是饮食失调的核心症状，预示着更大的慢性病和复发风险。关于饮食失调的不健康运动的详细概念化才刚刚开始出现，并且不健康运动的特定方面与饮食失调症状之间的联系很少受到关注。当前研究的目的是检查不健康运动的三个关键维度之间的关联-强迫性运动（即，规则驱动的运动以避免负面影响），控制体重/体形的运动以及为补偿近期食物摄入而进行的运动-限制饮食和暴饮暴食。参加者有239名女性，分别来自两项关于情绪和饮食行为的独立研究。126（52。7％）在过去三个月中批准了限制性饮食和/或客观暴食饮食发作。使用强迫运动测试和研究人员设计的项目测量不健康的运动尺寸，并使用饮食病理症状清单评估饮食失调症状。限制性饮食仅与避免和规则驱动的运动有关，而暴饮暴食与所有不健康的运动变量显着相关。多元回归结果表明，只有补充性运动才与暴饮暴食有关。不健康的运动包括与核心饮食失调症状有不同关系的部分不同的维度。
