Distorted representation of one's own body is a diagnostic criterion and corepsychopathology of disorders such as anorexia nervosa and body dysmorphic disorder. Previousliterature has raised the possibility of utilising physical activity intervention (PI) as atreatment option for individuals suffering from poor body satisfaction, which is traditionallyregarded as a systematic distortion in "body image." In this systematic review,conducted according to the PRISMA statement, the evidence on effectiveness of PI on body representation outcomes is synthesised. We provide an update of 34 longitudinal studies evaluating the effectiveness of different types of PIs on body representation. No systematic risk of bias within or across studies were identified. The reviewed studies show that the implementation of structured PIs may be efficacious in increasing individuals' satisfaction of their own body, and thus improving their subjective body image related assessments. However, there is no clear evidence regarding an additional or interactive effect of PI when implemented in conjunction with established treatments for clinical populations. We argue for theoretically sound, mechanism-oriented, multimethod approaches to future investigations on body image disturbance. Specifically, we highlight the need to consider expanding the theoretical framework for the investigation of body representation disturbances to include further body representations besides body image.
对自身身体的歪曲认知是神经性厌食症和身体变形障碍等疾病的诊断标准和核心精神病理学特征。以往文献提出了将体育活动干预（PI）作为身体满意度低的个体的一种治疗选择的可能性，身体满意度低传统上被视为“身体意象”中的一种系统性歪曲。在这项根据PRISMA声明进行的系统评价中，综合了关于体育活动干预对身体表征结果有效性的证据。我们更新了34项纵向研究，评估了不同类型的体育活动干预对身体表征的有效性。在各项研究内部或之间均未发现系统性偏倚风险。所审查的研究表明，实施结构化的体育活动干预可能有效地提高个体对自身身体的满意度，从而改善他们与主观身体意象相关的评估。然而，对于在临床人群中与既定治疗方法联合实施体育活动干预时的额外或交互作用，尚无明确证据。我们主张采用理论上合理、以机制为导向的多方法来开展未来关于身体意象障碍的研究。具体而言，我们强调需要考虑扩大身体表征障碍研究的理论框架，以纳入除身体意象之外的更多身体表征。
