Abstract:

In order to gain in-depth understanding of somatotype characteristics of elderly women and to classify the somatotype of elderly women scientifically, human body data of the elderly women aged from 60 to 80 years old in Dalian area were collected, and the somatotype characteristics of the elderly women in Dalian area were analyzed using principal component factor analysis, comparative analysis and K-means dynamic clustering method. The combination classification method was employed to achieve accurate somatotype subdivision. The results show that the chest and waist-abdomen are protruding obviously and the arms are longer in the elderly women in Dalian area. The somatotype of the elderly women can be divided into four types: normal type, short type, high chest type, fat broad chest type and obese wide chest protruding abdomen type. Based on the combination of chest-waist difference and hip-waist difference, the somatotype of elderly women is divided into four categories, with a population coverage rate of 96.57%. The reference values of the control position of the intermediate body are found to be height 160 cm, chest circumference 97 cm, waist circumference 86 cm, abdominal circumference 95 cm, hip circumference 97 cm, arm length 52 cm, total shoulder width 40 cm, which provides a theoretical basis for the design of elderly women's clothing.

Key words: somatotype characteristics, principal component factor analysis, K-means clustering, somatotype classification, elderly women in Dalian area
