이 연구는 2018년 세계태권도 그랑프리 대회에 참가한 50개국 남ㆍ여 선수들의 16강 이상의 경기영상(총 120게임)을 분석하여 태권도 겨루기의 과학적이고 체계적인 훈련프로그램의 기초자료를 제시하는데 목적이 있다. 영상분석을 통해 수집된 모든 자료는 spss 22.0을 이용하여 평균과 표준편차를 산출하였으며 남ㆍ녀 각각의 체급에 따른 발차기 횟수와 득점수, 득점율의 유의차를 검증하기 위하여 one-way ANOVA로 분석하였다. LSD를 이용하여 사후검증을 하였으며, 유의수준은 α=.05로 설정하였다. 남자경기에서 선제공격과 반격 발차기의 횟수는 +80kg체급보다 다른 체급 모두 유의하게 높았으며(-58kg, p<.001; -68kg & -80kg, p<.01) 수비 후 공격 발차기 횟수는 –58kg체급이 다른 체급들보다 유의하게 높았다(p<.001). 또한 근접공격 발차기 횟수는 -58kg체급이 -80kg체급(p<.01)과 +80kg체급(p<.05)보다 유의하게 높았으며, -68kg체급에서도 -80kg체급(p<.05)보다도 유의하게 높았다. 선제공격의 득점수는 -58kg체급과 –68kg체급에서 -80kg체급과 +80kg체급보다 유의하게 높았으며(p<.05), 근접공격의 득점수는 -58kg체급과 -68kg체급에서 -80kg체급(p<.05)보다 유의하게 높았다. 선제공격의 득점율은 -68kg체급에서 -80kg체급(p<.05)보다 유의하게 높았으며 수비 후 공격의 득점율은 -68kg체급이 -58kg체급(p<.05)보다 유의하게 높았고 근접공격의 득점율은 +80kg체급이 -58kg체급과 -68kg체급보다 유의하게 높았다(p<.01). 여자경기에서 선제공격(-49kg, & -57kg, p<.001; -67kg, p<.05)과 반격(-49kg, -57kg, & -67kg, p<.05)의 발차기 횟수는 +67kg체급보다 다른 체급 모두 유의하게 높았으며 수비 후 공격의 발차기 횟수는 -49kg체급에서 -67kg체급(p<.05)보다 유의하게 높았다. 선제공격의 득점수는 –57kg체급보다 다른 체급 모두 유의하게 높았으며(-49kg, -67kg, & +67kg, p<.05) 반격의 득점수는 -67kg체급이 다른 체급 모두 보다 유의하게 높았다(-49kg, p<.01; -57kg & +67kg, p<.001). 선제공격의 득점율은 –57kg체급보다 다른 체급 모두 유의하게 높았으며(-49kg, p<.05; -67kg & +67kg, p<.01) 반격의 득점율은 –67kg체급에서 다른 체급 모두 보다 유의하게 높았다(-49kg & +67kg, p<.05; -57kg, p<.001). 이러한 결과는, 자신과 상대선수에 대한 체계적인 경기 영상분석을 통한 개별 훈련프로그램이 태권도 겨루기의 경기력 향상을 위한 중요한 기초자료로서 충분히 활용될 것으로 사료된다.
The purpose of this study is to provide basic data for training programs of Taekwondo by analyzing the match videos (120 games in total) of males and females from 50 countries participating in the 2018 World Taekwondo Grand Prix. All data collected through image analysis were calculated using spss 22.0 for average and standard deviation. One-way ANOVA was analyzed to verify the significant difference in the number of kicks, scores, and scoring rates according to each weight class. Post-hoc verification was performed using LSD, and the significance level was set to α=.05. In male’s games, the number of preemptive attacks and counter-attack kicks was significantly higher in all other weight classes than in the +80kg weight class (-58kg, p<.001; -68kg & -80kg, p<.01) and the number of attack after defense kicks was significantly higher in the -58kg weight class than in other weight classes (p<.001). The number of close-attack kicks was significantly higher in the -58kg weight class than in the -80kg (p<.01) and the +80kg weight classes (p<.05) and also, the -68kg weight class was significantly higher than in the -80kg weight class (p<.05). The score of preemptive attack was significantly higher in the -58kg and -68kg weight classes than in the -80kg and +80kg weight classes (p<.05). The score of close-attack was significantly higher in the -58kg and -68kg weight classes than in the -80kg weight class (p<.05). The scoring rate of preemptive attack was significantly higher in the -68kg weight class than in the -80kg weight class (p<.05), and attack after defense was significantly higher in the -68kg weight class than in the -58kg weight class (p<.05). In addition the scoring rate of the close-attack was significantly higher in the +80kg weight class than in the -58kg and -68kg weight classes (p<.01). In female’s games, the number of preemptive attacks (-49kg, & -57kg, p<.001; -67kg, p<.05) and counter-attack (-49kg, -57kg, & -67kg, p<.05) kicks was significantly higher in all other weight classes than in the +67kg weight class and the number of attack after defense kicks was significantly higher in the -49kg weight class than in the -67kg weight class (p<.05). The score of the preemptive attack was significantly higher in all other weight classes than in the -57kg weight class (-49kg, -67kg, & +67kg, p<.05), and counter-attack was significantly higher in the -67kg weight class than in all other weight classes (-49kg, p<.01; -57kg & +67kg, p<.001). The scoring rate of preemptive attack was significantly higher in all other weight classes than in the -57kg weight class (-49kg, p<.05; -67kg & +67kg, p<.01) and counter-attack was significantly higher in the -67kg weight class than in all other weight classes (-49kg & +67kg, p<.05; -57kg, p<.001). These results suggest that individual training programs through systematic video analysis for oneself and opponents will be effects as important basic data for improving the performance of taekwondo competition.
