Abstract
People have recently became interested in eco-friendly cycling that attracted further attention as a sport activity. The number of high school cyclists has increased due to the popularity of cycling; however, high school cyclists have trouble choosing cycling suits because there is no professional cycling suit for high school cyclists in Korea. Therefore, it is necessary to develop a professional cycling suit for high school cyclists because sportswear for athletes is an important means to improve performance. This study suggests a standard sizing system for high school student athletes' cycle tights. The subjects were 111 high school cyclists. The 3 clusters were categorized by cluster analysis, and the sizing system was classified according to three lower body types. The size intervals of waist girth, hip girth and height were 5cm, respectively. The most frequent sizes were 75-100-175 in figure type 1, 70-90-170 and 75-95-170 in figure type 2, 70-90-175 and 70-90-180 in figure type 3. The sizing system, which had frequencies more than 3.6%, was classified into 9 cases, 8 cases, and 5 cases, respectively by lower body types. The results will contribute to the development of athletic performance cycle wear for high school cyclists.
