Physical Strength Is Not Associated With Facial Sexual Dimorphism and Asymmetry in Either Czechs or Cameroonians
Objectives
Handgrip strength is a widely used indicator of muscle strength and general health, but its association with facial morphology remains unclear. This study examined whether handgrip strength or its asymmetry is related to facial sexual shape dimorphism, perceived masculinity/femininity, and facial asymmetry in two culturally and genetically distinct populations: Cameroonian and Czech adults.
Methods
Geometric morphometric methods were applied to full-face portraits of 226 individuals (balanced by sex, aged 19–59), using 72 facial landmarks and semi-landmarks. Pearson correlations and a series of ANOVA analyses were then used to assess possible associations between facial traits and both absolute and asymmetric grip strength.
Results
Across all models and subgroups, associations between handgrip strength and facial morphology were weak and nonsignificant. None of the facial characteristics reliably predicted either handgrip strength or its asymmetry in either men or women.
Conclusions
These findings suggest that facial morphology on its own does not reliably reflect muscular strength. Further research should incorporate longitudinal and cross-cultural designs.
期刊介绍：
The American Journal of Human Biology is the Official Journal of the Human Biology Association.
The American Journal of Human Biology is a bimonthly, peer-reviewed, internationally circulated journal that publishes reports of original research, theoretical articles and timely reviews, and brief communications in the interdisciplinary field of human biology. As the official journal of the Human Biology Association, the Journal also publishes abstracts of research presented at its annual scientific meeting and book reviews relevant to the field.
The Journal seeks scholarly manuscripts that address all aspects of human biology, health, and disease, particularly those that stress comparative, developmental, ecological, or evolutionary perspectives. The transdisciplinary areas covered in the Journal include, but are not limited to, epidemiology, genetic variation, population biology and demography, physiology, anatomy, nutrition, growth and aging, physical performance, physical activity and fitness, ecology, and evolution, along with their interactions. The Journal publishes basic, applied, and methodologically oriented research from all areas, including measurement, analytical techniques and strategies, and computer applications in human biology.
Like many other biologically oriented disciplines, the field of human biology has undergone considerable growth and diversification in recent years, and the expansion of the aims and scope of the Journal is a reflection of this growth and membership diversification.
The Journal is committed to prompt review, and priority publication is given to manuscripts with novel or timely findings, and to manuscripts of unusual interest.
