Exposure to "fitspiration" may promote exercising for maladaptive weight and appearance reasons in young women. Fitness content depicting higher-weight bodies could promote exercise for adaptive non-appearance motives, and body compassion might protect against the negative effects of "fitspiration" exposure. Two pre-registered experimental studies examined (i) the effects of exposure to fit-normative vs. weight-inclusive Instagram images on young women's exercise intentions and motivations, and (ii) tested trait body compassion as a moderator of the relationships between image exposure and psychosocial exercise outcomes. Using an online experimental paradigm, young adult women were randomized to view Instagram images representing fit-normative, weight-inclusive, or control conditions and completed state measures of exercise intention and motivation. Study 1 (n = 228) employed a post-test design and found no significant effects of condition on exercise outcomes, nor an effect of body compassion. Using a pre- and post-experimental design in Study 2 (n = 797), participants in the weight-inclusive condition exhibited significantly greater increases in exercise intention and fitness/health motivation, while those in the fit-normative condition exhibited greater increases in weight/appearance motivation, compared to controls. Body compassion was not a significant moderator of the associations between exposure to weight-inclusive vs. fit-normative images and exercise outcomes. Exposure to fit-normative Instagram content may encourage dysfunctional exercise motives in young women. Weight-inclusive imagery may more effectively inspire adaptive exercise intentions and motivations, and future research should investigate how it may be leveraged to improve psychosocial exercise outcomes.

调查适合规范和包含体重的 Instagram 图片对女性锻炼动机的影响。

暴露于“fitspiration”可能会促进年轻女性因体重和外表不适应而进行锻炼。描绘体重较高的身体的健身内容可以促进适应性非外表动机的锻炼，而身体同情心可能会防止“健身”暴露的负面影响。两项预先注册的实验研究检查了（i）暴露于健康规范与包含体重的 Instagram 图像对年轻女性运动意图和动机的影响，以及（ii）测试特质体同情作为图像暴露之间关系的调节剂和社会心理锻炼结果。使用在线实验范式，年轻成年女性被随机查看代表适合规范、体重包容、或控制条件和完成的运动意图和动机状态测量。研究 1 (n = 228) 采用了后测设计，发现条件对运动结果没有显着影响，也没有身体同情的影响。在研究 2 (n = 797) 中使用实验前和实验后设计，体重包容条件下的参与者表现出运动意愿和健身/健康动机的显着增加，而健康规范条件下的参与者表现出更大的增加与对照组相比，体重/外观动机。身体同情不是暴露于体重和健康规范图像与锻炼结果之间关联的重要调节剂。接触合身规范的 Instagram 内容可能会鼓励年轻女性产生功能失调的锻炼动机。
