目的进食障碍患者经常进行适应不良的运动(例如，感觉被驱使，或为了“补偿”进食)，这维持了进食病理。从理论上讲，适应不良运动可以通过增强积极情绪(PA)和减少与狂欢发作和糟糕的身体形象相关的负面情绪(NA)来帮助患有EDS的个体调节情绪。然而，还没有研究考虑非适应不良运动的存在，也没有研究在狂欢频谱抑郁症中评估这一理论。方法本研究评估了运动前后的情感轨迹，并考察了运动类型(适应不良或非适应不良)作为调节因素。我们招募了患有狂欢频谱ED的成年人(N=1107；n=84认可运动)来完成为期7至14天的生态瞬时评估方案，评估NA(焦虑、内疚和悲伤)、PA(兴奋和欢快)和运动。结果运动前PA的上升轨迹显著二次曲线，表明PA的上升轨迹随着它靠近运动情节而趋于平缓。运动类型显著缓和了运动后PA的立方轨迹，使得PA的上升轨迹在非适应不良运动后数小时加速，而PA的下降轨迹在非适应不良运动后数小时加速。结论运动前PA的运动轨迹可能反映了对运动的积极期望。运动后PA的轨迹表明，非适应不良运动促进PA的增加。未来的研究应该评估运动何时以及对谁起到调节情绪的作用，并检查运动对勃起功能障碍的其他瞬时风险因素。公众意义患有勃起功能障碍的个人经常从事适应不良的运动(例如，感觉被驱使，或为了“补偿”饮食)。不适应运动已经被理论上用来帮助患有EDS的人调节情绪。这项研究评估了运动前后的情感轨迹，并检查了运动类型(适应不良或非适应不良)是否改变了这些轨迹。运动前PA的运动轨迹可能反映了对运动的积极期望。运动后PA的轨迹表明，非适应不良运动促进PA的增加。
ObjectiveIndividuals with eating disorders (EDs) often engage in maladaptive exercise (e.g., feeling driven, or to “compensate” for eating) which maintains eating pathology. Maladaptive exercise has been theorized to help individuals with EDs regulate emotions by enhancing positive affect (PA) and reducing negative affect (NA) associated with binge episodes and poor body image. However, no research has considered the presence of non‐maladaptive exercise or evaluated this theory in binge‐spectrum EDs.MethodsThis study evaluated affective trajectories pre‐ and post‐exercise and examined exercise type (maladaptive or non‐maladaptive) as a moderator. We recruited adults with binge‐spectrum EDs (N= 107;n= 84 endorsed exercise) to complete a 7‐ to 14‐day ecological momentary assessment protocol assessing NA (anxiety, guilt, and sadness), PA (excitement and cheerfulness), and exercise.ResultsThere was a significant quadratic trajectory of PA pre‐exercise, suggesting that the upward trajectory of PA leveled out as it moved closer to an exercise episode. Exercise type significantly moderated the cubic trajectory of PA post‐exercise, such that the upward trajectory of PA accelerated in the hours following non‐maladaptive exercise episodes while the downward trajectory of PA accelerated in the hours following maladaptive exercise episodes. No trajectories of NA demonstrated significant effects.ConclusionsPre‐exercise trajectories of PA may reflect positive expectancies around exercise. Post‐exercise trajectories of PA suggest that non‐maladaptive exercise promotes increased PA. Future research should evaluate when, and for whom, exercise serves to regulate affect and examine other momentary risk factors of exercise in EDs.Public SignificanceIndividuals with EDs often engage in maladaptive exercise (e.g., feeling driven, or to “compensate” for eating). Maladaptive exercise has been theorized to help individuals with EDs regulate emotions. This study evaluated affective trajectories pre‐ and post‐exercise and examined whether exercise type (maladaptive or non‐maladaptive) changed these trajectories. Pre‐exercise trajectories of PA may reflect positive expectancies around exercise. Post‐exercise trajectories of PA suggest that non‐maladaptive exercise promotes increased PA.
