초록

본 연구는 태권도 전문 기능화 개발을 위한 제안으로서 고급기술의 사용과 기능을 고려하여 회전력이 강화된 전문태권도화의 운동역학적인 특징을 분석하고자 하였다. 연구방법은 2가지 태권도화 종류를 이용하여, 텐션마찰계수 측정계와 지면반력기를 이용하여 얻은 결론은 다름과 같다. 정적마찰계수 비교는 A사 0.60, M사 0.61로 나타났다. 모멘트(회전 마찰력) 비교는 M사 태권도화가 회내(3.23Nm), 회외(2.70Nm) 모두 A사 태권도화 회내(3.20Nm), 회외(2.62Nm) 보다 높게 나타났다. 지면반력 비교는 Fz의 값은 세가지 조건에서 각각 유의한 차이가 있는 것으로 나타났으며(p<0.05), Fy의 최고의 힘은 세가지 조건에서 유의한 차이가 없는 것으로 나타났다. Fx 보다 앞서 나타나는 피크의 형태를 보여주고 있다.

The purpose of this study was to compare the biomechanical difference of barefoot and two types taekwondo footwear. which will provide scientific data to coaches and players, to further prevent injuries and to improve each players skills. How to an effect on human body which studied a kinematics and kinetics from 8 college students during experiments. This study imposes several conditions by barefoot and two types of taekwondo footwear ran under average $3.82{\pm}0.59$ m/sec for kinetics analysis. The result of comparative analysis can be summarized as below. Friction coefficient analysis showed A Company shoes 0.60 and M Company shoes 0.61. Ground reaction force also showed that statically approximates other results from impact peak timing (p<0.001), Maximum loading rate (p<0.001), Maximum loading rate timing (p<0.001) and impulse of first 20 percent (p<0.001). Moment was M Company shoes bigger than A Company shoes to pronation moment and supination moment.
