Previous studies have demonstrated that the angle of women's lumbar curvature affects men's attractiveness judgments of them. The theoretically optimal angle of lumbar curvature provides better resistance against both hyperlordosis and hypolordosis as biomechanical costs of a bipedal fetal load that could impair a woman's fertility. Since men find this attribute attractive, women aim to emphasize it by wearing high-heeled shoes. The primary objective of the present study was to test this evolutionary hypothesis using short videos presenting women walking by the camera. In line with previous findings based on static stimuli (photographs), dynamic stimuli (videos) presenting women walking in high-heeled shoes were expected to elicit increased attractiveness ratings as compared to women wearing flat shoes, which would be associated with the angle of lumbar curvature. Videos were taken of 52 female models walking in two conditions (i.e., wearing either high-heeled or flat shoes). A total of 108 participants (61 males, 47 females) rated the walking models' physical attractiveness in an online setting. Each model's lumbar curvature was measured both in high heels and in flat shoes using photographs taken of them prior to each video recording. The results showed that wearing high heels consistently increased the models' attractiveness, regardless of whether or not it decreased their natural difference from the theoretically optimal angle of lumbar curvature. Both male and female observers showed this positive effect. Furthermore, a negative correlation was found between the models' body mass index (BMI) and their perceived attractiveness scores in both conditions.
先前的研究表明，女性腰椎曲度的角度会影响男性对她们的吸引力判断。腰椎曲度的理论最佳角度为双足胎儿负荷的生物力学成本提供了更好的抵抗力，这可能会影响女性的生育能力。由于男性认为这一属性具有吸引力，女性会通过穿高跟鞋来强调这一点。本研究的主要目的是使用展示女性向摄像机走来的短视频来检验这一进化假设。与基于静态刺激（照片）的先前发现一致，与穿平底鞋的女性相比，预计穿着高跟鞋行走的女性会因动态刺激（视频）而获得更高的吸引力评分，这与腰椎曲度有关。对 52 名女性模特在两种情况下（即穿高跟鞋或平底鞋）行走的视频进行了拍摄。共有 108 名参与者（61 名男性，47 名女性）在线对行走模特的身体吸引力进行了评分。在拍摄每个视频之前，使用照片测量了每个模特在高跟鞋和平底鞋中的腰椎曲度。结果表明，无论是否降低了其自然与腰椎曲度理论最佳角度的差异，高跟鞋的穿着始终会增加模特的吸引力。男性和女性观察者都表现出这种积极的影响。此外，在两种情况下，模型的体重指数（BMI）与他们的感知吸引力得分之间都存在负相关关系。
