Abstract

본 연구의 목적은 테니스화의 종류에 따른 주행 특성 및 테니스 동작 수행 시 족저압력분석 방법을 활용하여 테니스화의 기능성을 평가하는데 있다. 하지의 상해가 없고 정상적인 보행동작을 수행하는 남자 대학생 10명을 선정하여 4종류 모델의 테니스화를 대상으로 직선주행, <TEX>$45^{\circ}$</TEX> 방향전환주행, 포핸드 스트로그, 백핸드 스트로그 동작 시 족저압력을 측정한 후 COP(renter of pressure)경로, 평균족저압력, 최대족저압력, 최대지면반력을 분석하였다. 분석결과 직선달리기 동작 시 족저압력 분석결과 모든 제품이 우수한 것으로 분석되었고 통계적으로 유의미한 차이는 없었으며, <TEX>$45^{\circ}$</TEX> 방향전환달리기동작, 포핸드 스트로그동작, 백핸드 스트로그 동작 시 최대지면반력과 최대족저압력 그리고 평균족저압력을 종합적으로 분석해 본 결과 통계적으로 유의미한 차이는 없었으나, C>A>B>D> 순으로 테니스화의 기능성이 우수한 것으로 분석되었다. The purpose of this study was to analyze the foot-pressure distribution of Tennis Shoes for assessing their functionality. 10 university male students (shoe size: 265mm) who had no history of injury in the lower extremity and a normal gait pattern participated in this study. Four types of tennis shoes, most popular in Korea (A, B, C & D company), were selected and tested. Using the PEDAR-X system and PEDAR-X insoles, 4 different motion stages were analyzed for the foot-pressure distribution: (a) straight running; (b) c-cut(<TEX>$45^{\circ}$</TEX> left turn running; (c) forehand stroke; and (d) backhand stroke. Results revealed that in all stages, there were no statistically significant differences among the types of shoes; however, descriptive statistics indicated that functionality of shoe types was somewhat different depending on the type of stages. The order in functionality found was C>A>B>D.
