Abstract：
Driven exercise (i.e., feeling compelled to exercise to control one\'s weight or shape, to obtain other positive consequences of exercising, or to avoid other negative consequences of not exercising) is a common phenomenon in individuals with eating disorders (EDs), typically associated with negative clinical outcomes. Current theoretical models of driven exercise highlight the short-term affect-regulating outcome of acute driven exercise, which is implicated to maintain this symptom either by positive or negative reinforcement. However, few studies have actually investigated cognitive, affective, and psychobiological mechanisms related to acute driven exercise. In particular, experimental studies that directly test mechanisms leading to the short-term affective improvement after acute driven exercise are scarce. In this article, we therefore propose potential cognitive, affective, and psychobiological mechanisms that could explain the affect-regulating function of driven exercise in individuals with EDs. In addition, we suggest examples of experimental studies that could directly test these mechanisms in individuals with EDs, as recent studies have demonstrated the safety of supervised exercise in EDs research. Our aim of stimulating research on the underlying causes and maintenance factors of driven exercise in EDs has the potential to critically inform treatment development for this high-risk population.
摘要：
驱动运动(即，感觉被迫锻炼以控制自己的体重或形状，为了获得锻炼的其他积极后果，或避免不锻炼的其他负面后果）是饮食失调（ED）个体的普遍现象，通常与阴性临床结果相关。当前驱动运动的理论模型突出了急性驱动运动的短期影响调节结果，这意味着通过积极或消极的强化来维持这种症状。然而,很少有研究真正调查认知，情感,以及与急性驱动运动相关的心理生物学机制。特别是,缺乏直接测试导致急性驱动运动后短期情感改善的机制的实验研究。在这篇文章中,因此，我们提出了潜在的认知，情感,和心理生物学机制可以解释驱动运动在ED患者中的情感调节功能。此外,我们提出了一些实验研究的例子，可以直接在患有ED的个体中测试这些机制，最近的研究证明了ED研究中监督运动的安全性。我们旨在刺激对ED中驱动运动的根本原因和维持因素的研究，有可能为该高危人群的治疗发展提供关键信息。
