Abstract: BACKGROUND: Currently, forensic anthropology, ergonomics and footprint studies have all found that there is a significant correlation between foot information (such as foot length and foot width) and body height and mass. However, there is no enough quantitative research on barefoot morphological characteristics contact area (BMCCA) as well as human body height and mass.
OBJECTIVE: To analyze the correlation between BMCCA and body mass and height, and to innovate the theoretical systems of forensic anthropology and ergonomics, thereby providing reference for individual recognition by barefoot footprint.
METHODS: Samples were collected using traditional plane footprint ink printing method, and digital software MATLAB was then used for image processing. A total of 100 healthy young men with a height distribution between 165-190 cm were randomly selected as subjects. Body height and mass were recorded. BMCCA was obtained under normal walking for statistical analysis. The implementation of the study complied with the Declaration of Helsinki and the relevant ethical requirements of Criminal Investigation Police University of China.
RESULTS AND CONCLUSION: For healthy young men with normal arch of the foot (excluding interrupted arch of the foot and expanded arch of the foot), there is a significant positive correlation between BMCCA and height and mass (P < 0.01). The relationship between BMCCA and human body height can be applied for height analysis in forensic anthropology, ergonomics, and footprint. Compared with body mass, body height has a more significant impact on BMCCA and is more directly related.
