Associations between physical activity, reasons for being physically active, physical attractiveness, limbus ring perception, and lumbar curvature

Our ancestors obtained significant survival and reproductive advantages if they chose their ma-tes wisely. Many attractiveness evaluation processes focus on visual cues that were predictive of reproductive fitness in evolutionary contexts, like the limbal ring, a black ring formed at the intersection between the iris and sclera in the human eye. Those with more pronounced limbal rings are perceived as more attractive (Brown & Sacco, 2018; Peshek et al., 2011, 2013). An-other cue is the Lumbar curvature angle in women. It was found to influence a woman's attrac-tiveness, possibly because of its function in bipedal fetal load and sexual receptivity (Lewis et al., 2015; Pazhoohi et al., 2022). This study explored correlations and new hypotheses between the latest findings in attractiveness perception and physical activity. The 149 study participants were questioned about their preference for Lumbar curvature angle/range of motion and limbal ring presence.
Further, questionnaires were completed on their physical activity level (SGB) and openness to short-term mating (SOI-R.). T-tests, one-way ANOVAs, and Spearman correlation tests were used for statistical analysis. This study found compelling evidence that females with a greater range of motion in their lumbar curvature are perceived as more attractive in a short-term mat-ing context. Furthermore, it found compounding evidence for intrasexual competition in women. Finally, this current study found significant evidence that the more active a person is, the more open to short-term mating they are. These findings could provide a starting point for further investigations into understanding human physical appearance-enhancement behavior.
