Although the electronic body protector has been officially adopted by the World Taekwondo Federation(WTF) in 2006, no scientific information is available about the reliability of its performance. The purpose of this study, therefore, was to investigate the relationship between the impact value of electronic body protector and the impact force of force platform. Male collegiate Taekwondo athletes([MCTA], n=21) and male collegiate Taekwondo students([MCTS], n=20) volunteered to participate in the study. Each subject performed the apchagi, dollyeochagi and dwichagi on the force platform and the electronic body protector. At the apchagi, it showed that MCTS(about 4,700 N) generated more maximum kick force than MCTA(about 3,900 N), but it expressed that MCTA(about 5,300 N) generated more maximum kicking force than MCTS(about 4,400 N) at the dwichagi. At the apchagi and the dwichagi, it indicated the high coefficient of correlation(over r=.8) which supports higher explanation force the relationship between the impact value of electronic body protector and the impact force of force platform, but there was no statistically significant difference at the dollyeochagi.

본 연구는 현재의 복잡하며 부정확한 기존의 태권도 전자호구 시스템과 차별화 되는 전자호구 개발을 제안한다. 이를 위해 전자호구에 적용이 가능한 다양한 센서(마그네틱 센서, 전기용량 센서, 접촉식 스위치 방식, 압전필름 센서) 방식에 대하여 시험을 통해 분석하여 차별화된 성능을 가질 수 있는 센서 방식을 제안한다. 제안하는 전자호구의 타격에 대한 정도를 높이기 위해 기존의 몸통호구에만 집약된 광범위한 센서 및 무선 통신 제어 장치를 호구와 손, 발 보호대로 분산하였다. 또한 몸통호구에는 초경량 필름형 압전센서를 통해 몸통호구에 가해지는 충격량을 측정하도록 하여 무게를 경량화 하였다. 기존의 전자호구의 경우 몸통호구에 집약된 센서 및 통신 제어 장치를 개별 장비로 분리하여 사용자가 개별 구입할 수 있도록 스마트 앱을 활용하여 스코어를 확인할 수 있도록 하였다. 개발하는 전자호구의 무게는 약 1kg 이하로 기존 대비 20% 정도 감소되는 효과를 얻었다. 완벽한 시험 환경을 갖추지 못하여 충격량에 대한 효과를 정확하게 분석하지 못한 부분은 본 연구의 보안 사항을 본다.

This research was to develop Taekwondo trunk protector(Hogu) and head protector's sizing systems corresponding the regulations by World Taekwondo Association. These sizing systems were established using 2003-2004 Size Korea anthropometric data. The result can be summarized as follows: According to the analysis of correlation, most measurements had high relationship with weight for Hogu and head girth for head protector. Six sizes(47, 54, 59, 64, 70, 76) for Hogu and 4 sizes(52, 54, 56, 60) for head protector were suggested in this study. Hogu sizes indicate body weights and head protector sizes express head girth measurements. By the comparison between current Hogu sizes and new sizes, the smaller sizes of new Hogu were bigger than current sizes in bust girth, back fastening length, shoulder length. On the other hand, the bigger sizes of new Hogu were larger than current sizes in bust girth, back fastening length, shoulder length. In addition, new Hogu's lengths were shorter than current Hogu in all sizes. The lengths of Neck to collar bone in new Hogu sizes were longer than current Hogu. In case of the head protector, there were no measurements besides outer circumference of helmet in recognized specifications of WTF. Therefore some referable measurements such as head girth, head length, bitragion arc, sagital arc were suggested in new size specification. When helmet sizes were suggested, the thickness of the NBR foam also were considered.
