The purpose of this study is to provide the basic data necessary for establishing a system for analyzing the dimensions and body types of men aged 30–59. The subjects were 1,247 adult males selected based on data from the 8th Korean anthropometric survey; the direct and calculated values constituted 36 items; and descriptive statistics analysis, factor analysis, and cluster analysis were conducted. the descriptive statistics analysis revealed that the weight difference between individuals was high, while the height difference was low. Overall, the differences between individuals were high in waist-related items and low in lower limb circumference-related items. It was found that knee height and hip side length increased in subjects aged in their late 30s and decreased in those aged in their early 50s, while lower leg circumference decreased with age from the late 30s onward. The factor analysis identified four dimensions: “horizontal size of lower body,” “vertical size of lower body,” “hip length,” and “ankle size.” on the basis of the cluster analysis, they were classified into the following types: “tall body shape with long waist and hips, bent legs and hips, thick legs and ankles,” “slim body shape with short legs and short hips,” and “slim body shape with short legs and thin ankles.” A follow-up study is required to analyze changes in body shape over time based on annual measurements. We believe that this study will furnish basic data for establishing a measurement system for men’s clothing.

This study aimed to identify changes in upper body measurements and body shape types among women over a 10-year period based on data from the 6th and 8th Size Korea Anthropometric Surveys. The study used regression analysis to explore the relationship between various dimensions, enabling the prediction of different upper body dimensions based on height and waist circumference. The sample consisted of 1,179 women in their 20s who participated in the 6th (2010) and 8th (2020) Size Korea Anthropometric Surveys, with 33 items analyzed. Initially, most items, except those related to height, exhibited larger values in the 8th Survey than in the 6th, suggesting a general increase in the upper body dimensions of females in their 20s over the 10-year period. Subsequent factor analysis revealed three factors crucial for determining the upper body shape of women in this age group. The body shapes were then categorized into four distinct clusters. Regression analysis indicated that both waist circumference and height significantly influence most of the measured items, with waist circumference having a more substantial impact in most models. Through this research, we aim to provide foundational data that reflects the evolving upper body shapes of women in their 20s to enhance clothing production and improve the sizing system.

  This study determined the optimal positions of the movable steering wheel and pedal systems of industrial vehicle by various body dimensions. The position of objects and starting driving posture were measured by Martin-type anthropometer and goniometer.
