Abstract：
While exercise is generally associated with positive health outcomes, in the context of eating disorders, exercise has high potential to become maladaptive. Maladaptive exercise is compelled or compulsive in nature for the purposes of weight and shape control or to obtain/avoid other eating disorder-relevant consequences. A transdiagnostic eating disorder feature with moderate-to-high prevalence across restrictive- and bulimic-spectrum eating disorders, maladaptive exercise is often associated with negative mental and physical health sequalae. Several proposed threat- and reward-related biobehavioral mechanisms may initiate or perpetuate maladaptive exercise. While exercise is generally contraindicated during periods of acute medical concern, adaptive forms of exercise are also present among those with eating disorders, and facilitation of adaptive exercise has potential to promote physical and mental health benefits during eating disorder recovery. Detailed assessment and targeted interventions are needed to address the clinical conundrum of how and when to integrate exercise into eating disorder treatment.
摘要：
虽然运动通常与积极的健康结果相关，在饮食失调的背景下，锻炼很有可能变得适应不良。出于体重和形状控制或获得/避免其他饮食失调相关后果的目的，适应性不良运动在本质上是强迫或强迫性的。一种跨诊断性饮食障碍特征，在限制性和暴食性饮食障碍中具有中度至高度患病率，适应不良的运动通常与负面的身心健康后遗症有关。提出的几种与威胁和奖励相关的生物行为机制可能会引发或延续适应性不良运动。虽然运动通常在急性医疗问题期间是禁忌的，适应性锻炼形式也存在于那些饮食失调的人中，和促进适应性运动有可能促进饮食失调恢复期间的身心健康益处。需要详细的评估和有针对性的干预措施来解决如何以及何时将运动纳入饮食失调治疗的临床难题。
