Abstract

The purpose of this study is to compare and analyze the effects of stepping-in-place tempo and roundhouse kick types on response time. Fifteen males participated in this experiment. All have over ten years of experience and hold a forth dan(degree) black belt in taekwondo. The task is when the participants are doing stepping in place they respond to the light stimulus as fast as they can do roundhouse kick. Five different stepping in place tempos (100, 120, 140, 160, and 180 bpm) and four different types of roundhouse kick(front leg body roundhouse kick, front leg head roundhouse kick, back leg body roundhouse kick, and back leg head roundhouse kick) were used. Three measurements were taken for each of the different combinations of conditions for a total of 60 measurements. For data analysis, two-way ANOVA with repeated measures was used and pair-wise comparisons were performed using bonferroni statistics. The results show that there was significant difference interaction effect between stepping in place tempo and roundhouse kick type in the response time. And, there were significant difference in main effect of response time in accordance with stepping in place tempo and roundhouse kick type. The response time of roundhouse kick was the fastest at 160 bpm of stepping in place tempo, but there was no significant difference between 140 and 160 bpm. Front leg body roundhouse kick was the fastest. And, the response time was the fastest when front leg body roundhouse kicked at 140 bpm of stepping in place tempo. Stepping in place tempo between 140 and 160 bpm is the most effective to optimize the response time. And, More effective response time was front leg roundhouse kick as compared with back leg roundhouse kick and, body roundhouse kick as compared with head roundhouse kick. The findings in this study will provide useful information for performance improvement and will help with strategy for taekwondo competition.

본 연구의 목적은 제자리딛기 템포와 돌려차기 유형이 응답시간에 미치는 영향을 비교 분석하는데 있다. 본 연구에는 태권도 4단이며 10년 이상 수련한 남자 15명이 참여하였다. 실험 과제는 메트로놈의 템포에 맞춰 제자리딛기를 하다가 불빛 자극이 제시되면 최대한 빠르게 돌려차기를 하는 것이다. 5가지의 제자리딛기 템포(100, 120, 140, 160, 180 bpm)와 4가지의 돌려차기 유형(앞발 몸통 돌려차기, 앞발 얼굴 돌려차기, 뒷발 몸통 돌려차기, 뒷발 얼굴 돌려차기)에서 3회씩 총 60회를 실시하였다. 통계분석은 반복 측정 이원분산분석을 실시하였으며, 주효과의 대응별 비교는 Bonferroni를 실시하였다. 제자리딛기 템포와 돌려차기 유형의 상호작용효과가 나타났으며, 제자리딛기 템포와 돌려차기 유형에 따른 주효과도 나타났다. 160 bpm의 제자리딛기 템포에서 돌려차기의 응답시간이 제일 빠른 것으로 나타났다. 하지만 140과 160 bpm의 제자리딛기 템포에서 돌려차기 응답시간은 거의 차이가 나타나지 않았다. 앞발 몸통 돌려차기의 응답시간이 빨랐다. 그리고 제자리딛기 템포와 돌려차기 유형에 따라 140 bpm의 제자리딛기 템포에서 앞발 몸통 돌려차기의 응답시간이 가장 빠른 것으로 나타났다. 결론적으로 돌려차기의 응답시간은 140과 160 bpm의 제자리딛기 템포에서 효과적이며, 뒷발보다는 앞발, 얼굴보다는 몸통 돌려차기가 효과적인 것으로 나타났다. 본 연구를 통해 도출된 결과는 수행 향상에 유용한 정보를 제공할 것이며, 태권도 경기를 위한 전략에 도움이 될 것이다.
