This experiment examined the effects of exposure to physique-salient (PS) and physique non-salient (PNS) exercise videos and the moderating influence of perceived physique discrepancies, on body image, self-presentational concerns, and exercise motivation. Eighty inactive women (M age=26) exercised to a 30 min instructional exercise video. In the PS condition, the video instructor wore revealing attire that emphasized her thin and toned physique. In the PNS condition, she wore attire that concealed her physique. Participants completed pre- and post-exercise measures of body image, social physique anxiety (SPA) and self-presentational efficacy (SPE) and a post-exercise measure of exercise motivation and perceived discrepancies with the instructor's body. No main or moderated effects emerged for video condition. However, greater perceived negative discrepancies were associated with poorer post-exercise body satisfaction and body evaluations, and higher state SPA. There were no effects on SPE or motivation. Results suggest that exercise videos that elicit perceived negative discrepancies can be detrimental to women's body images.
本实验考察了观看凸显体型（PS）和非凸显体型（PNS）的锻炼视频的影响，以及感知到的体型差异的调节作用，对身体意象、自我呈现关注和锻炼动机的影响。80名不活跃的女性（平均年龄 = 26岁）跟着一段30分钟的指导性锻炼视频进行锻炼。在PS条件下，视频中的教练穿着暴露的服装，凸显她苗条且线条优美的体型。在PNS条件下，她穿着能遮住体型的服装。参与者在锻炼前后完成了身体意象、社交体型焦虑（SPA）和自我呈现效能（SPE）的测量，并在锻炼后完成了锻炼动机以及与教练体型的感知差异的测量。视频条件未产生主效应或调节效应。然而，更大的感知到的负面差异与锻炼后较差的身体满意度和身体评价以及更高的状态性SPA相关。对SPE或动机没有影响。结果表明，引发感知到的负面差异的锻炼视频可能对女性的身体意象有害。
