Abstract:

In order to find a reasonable and convenient classification method for somatotypes, 407 Eastern China young women aged 20-35 were measured anthropometrically using a 3-D scan system, and 66 somatotype indices of each sample were manually measured using reverse engineering software. The main components related to human body shapes were extracted by using factor analysis. Based on the main components, the somatotype characteristic variables were extracted using correlation analysis and other analysis methods. The characteristic variables of human body shapes were analyzed by hierarchical clustering method. Consequently, under-bust flatness ratio, ratio of height-waist, chest-waist difference and hip-waist difference were extracted from the main components. The human body shapes were divided by using the under-bust flatness ratio as the characteristic variable. The body shapes were divided into 14 types based on the somatotype characteristic variables of the ratio of height-waist, chest-waist difference and hip-waist difference. The results show that significant differences between the body types exist and the classification results are reasonable and effective.

Key words: somatotype, somatotype classification, young women, under-bust flatness ratio, ratio of height-waist, chest-waist difference, hip-waist difference
