태권도복 소재별 인체생리반응과 주관적 감각에 관한 연구 = Physiological Responses and subjective sensations of the human wearing three different materials of Taekwondo wears

다국어 초록 (Multilingual Abstract)

The purpose of this study was to evaluate thermal properties of Taekwondo wears with three different materials. As a begging step, the questionnaire survey about the actual condition of Taekwondo wears was conducted. With the results of the questionnaire, cotton/nylon(70/30) blended fabric(CN) that was newly woven with sweat absorbent finishing and cotton/spandex(95/5) blended fabric with flexibility property were developed. The same designed 3 Taekwondo wears with 3 different materials which were two different materials(CN and CS) and a current material(cotton/PET, CP) were made. Four young males volunteered for this study, they kicked and punched as Taekwondo action for 20 minutes. Mean skin temperature was the highest in CS(33.1±O.8℃) and the lowest in CP(32.7±0.6℃). Increasing degree of rectal temperature didn`t show any significant difference. Clothing microclimate temperature on the thigh was higher in CS(32.8±17.4℃) than in CN(29.4±1.1℃) and CP(29.4±1.0℃). Clothing microclimate temperature on the back and humidity on the thigh didn`t show any significant differences. Clothing microclimate humidity on the back was higher in CP(65±20%RH) than in CS(61±17%RH). Heart rate, total body weight loss, and local sweating were not significantly different by materials. Most subject responded more hot in CN than in others, but there were no significant differences at the subjective sensation of thermal humidity. They answered more comfortable in CN than in others. Tectile sensations were the best in CN and the worst in CS. From those results, first of all, it is necessary to be weighted on Taekwondo wears made of CN in the aspects of the dignity of military arts uniform. Secondly, CS was required to be lighted and enhanced for the subjective sensation. Third, CP weaved honey comb was asked more various design to eliminate sweat high competition power within the scope of the dignity of military arts uniform.
