The effects of a physical exercise session on state body image and mood were examined. In a cross-over design, participants were randomised to two groups starting either with physical exercise (PE; experimental condition) or with reading a newspaper (RN; control condition). Before and after PE and RN, participants (N = 65) rated their body dimensions using a digital photo distortion technique and indicated their attitudinal body image and mood. Participants' judgements of their 'felt' body dimensions and attitudes toward their own body were affected differently by PE and RN, indicating that participants felt slightly slimmer and were more satisfied with their bodies after PE. Exercise-induced changes in body perception were greater, the higher the pre-experimental drive for thinness, body dissatisfaction and weight/shape concerns were. Especially in those participants with higher body image disturbances, physical exercise can have a reinforcing effect on immediate body image and mood improvement.
研究了一次体育锻炼对状态身体意象和情绪的影响。采用交叉设计，参与者被随机分为两组，一组先进行体育锻炼（PE；实验组），另一组先阅读报纸（RN；对照组）。在进行 PE 和 RN 之前和之后，参与者（N=65）使用数字照片变形技术对自己的身体尺寸进行评分，并表明他们的态度身体意象和情绪。PE 和 RN 对参与者对自己“感觉”的身体尺寸的判断和对自己身体的态度有不同的影响，这表明参与者在进行 PE 后感觉自己稍微苗条了一些，对自己的身体更加满意。对身体感知的锻炼引起的变化更大，对瘦身、身体不满和体重/形状担忧的预先实验驱动力越高。特别是对于那些身体形象障碍较高的参与者，体育锻炼可以对即时的身体形象和情绪改善产生强化作用。
