Obese women (N = 107) enrolled in a YMCA-based exercise and nutrition information program completed rating scales of satisfaction with one's body, self-efficacy related to exercise, physical self-concept, and overall mood, at baseline and at Week 24. Percent of exercise session attendance was also calculated. Multiple regression analysis, with entry of score changes in Body Areas Satisfaction, Exercise Self-efficacy, and Physical Self-concept as predictors of change in Total Mood Disturbance, was significant (R2 = .41, p < .001). Exercise session attendance was not significantly related to change in Total Mood Disturbance scores. Present findings supported behavioral explanations of the exercise-mood change relationship in this cross-sectional investigation. Replications with control groups, direct measurement of biochemical markers, and nonselective samples with different characteristics in different contexts with longitudinal designs are required.
肥胖女性（N=107）参加了一个基于基督教青年会的运动和营养信息计划，在基线和第 24 周完成了对身体满意度、与运动相关的自我效能感、身体自我概念和整体情绪的评定量表的评估。还计算了锻炼课程的出勤率。多元回归分析，以身体部位满意度、运动自我效能感和身体自我概念的分数变化为预测因子，预测总情绪困扰的变化，结果具有统计学意义（R2=0.41，p<0.001）。锻炼课程的出勤率与总情绪困扰评分的变化没有显著相关性。本研究结果支持了在这项横断面研究中对锻炼与情绪变化关系的行为解释。需要在不同背景下进行具有对照组、生化标志物直接测量和不同特征的非选择性样本的复制研究，并采用纵向设计。
