Despite the many benefits of regular, sustained exercise, there is evidence that exercise can become addictive, to the point where the exerciser experiences negative physiological and psychological symptoms, including withdrawal symptoms upon cessation, training through injury, and the detriment of social relationships. Furthermore, recent evidence suggests that the etiology of exercise addiction is different depending on the presence or absence of eating disorders. The aim of this study was to explore to what extent eating disorder status, body dysmorphic disorder, reasons for exercise, social media use, and fitness instructor status were associated with exercise addiction, and to determine differences according to eating disorder status. The key findings showed that the etiology of exercise addiction differed according to eating disorder status, with variables including social media use, exercise motivation, and ethnicity being uniquely correlated with exercise addiction only in populations with indicated eating disorders. Furthermore, body dysmorphic disorder was highly prevalent in subjects without indicated eating disorders, and could be a primary condition in which exercise addiction is a symptom. It is recommended that clinicians and practitioners working with patients who present with symptoms of exercise addiction should be screened for eating disorders and body dysmorphic disorder before treatments are considered.
尽管定期、持续锻炼有诸多益处,但有证据表明锻炼可能会上瘾,以至于锻炼者会出现负面的生理和心理症状,包括停止锻炼时的戒断症状、受伤仍坚持训练以及对社会关系的损害。此外,最近的证据表明,根据是否存在饮食失调,锻炼成瘾的病因有所不同。本研究的目的是探讨饮食失调状况、身体变形障碍、锻炼原因、社交媒体使用情况以及健身教练身份在多大程度上与锻炼成瘾相关,并根据饮食失调状况确定差异。关键研究结果表明,锻炼成瘾的病因因饮食失调状况而异,包括社交媒体使用、锻炼动机和种族等变量仅在有明确饮食失调的人群中与锻炼成瘾存在独特关联。此外,身体变形障碍在无明确饮食失调的受试者中非常普遍,并且可能是锻炼成瘾作为症状出现的主要情况。建议在考虑对有锻炼成瘾症状的患者进行治疗之前,临床医生和从业者应对其进行饮食失调和身体变形障碍的筛查。
