이 연구는 태권도 경기규칙에서 규정하는 경기운영형태를 바탕으로 승패를 결정하는 경기내용을 비교 분석하려는 목적으로 수행되었다. 이 목적을 위하여 2010년 전국체육대회의 태권도 74경기(일반부: 60명, 대학부: 88명)를 대상으로 공격기술, 공격유형, 득점유형, 승패관련 변인을 선정하였다. 이 연구의 목적을 위해 경기운영형태는 대한태권도협회(태권도경기규칙, 2010)에서 규정하고 있는 경기규칙을 준거로 ``코트 중앙 점유 유형``, ``코트 중앙경기 유형``, ``코트 외각경기 유형``으로 정의하였다. 영상기반의 분석도구인 Sports Code pro.ver을 활용하여 경기 중에 발생하는 변인 및 경기운영형태를 수량화 하였으며, 경기내용의 비교분석을 위하여 윈도우용 SPSS 17.0 통계프로그램을 이용하였다. 빈도, 백분율, χ2 검정을 실시하였으며, 이때 유의도 수준은 .05로 설정하여 검증하였다. 이 연구과정을 통하여 얻어진 결론은 다음과 같다. 태권도 경기에서 코트 중앙을 점유하거나 코트 중앙에서 경기를 수행할 때 보다 득점 및 실점에 효율적인 경기 운영형태를 보였다(χ2 = 6.842, p =.033). 승자집단은 코트 외각에서 역습공격에 의한 경기운영형태(61회, 47.3%)를 나타내었으며, 패자집단은 코트 중앙을 점유한 선제공격을 통해 경기를 운영(81회, 53.6%)하는 측면을 보였다. 또한 태권도 경기운영형태에 따라 전체 432개의 득점 중 ``돌려차기`` 기술을 활용한 득점이 193점으로 가장 많았으며, 코트 중앙을 점유한 경기운영형태에서 상대방의 경고에 의한 반칙이 48점으로 높은 측면은 보였다. The purpose of this study was to analyze on notational contents (winning and losing factor) of game tactics in taekwondo. To carry out this research, used 74 games on 2010 national taekwoindo games for male taekwondo players. The data form this study were using video analysing system of sports code pro. ver and analyzed frequency, percent and chi-square using spss 17.0 statistics program. The result of this study were as following: Firstly, It is more effective factor that discriminates between winer and loser to tactics on center ground. Secondly, according to the attack tactics between winner and loser, there are significant differences to the earned tactics on center ground. it was shown that winner group head start of attack was shown greater than loser group. The further researches are required on the development of variety game tactics.

정광채(Jung, Gwang-Che),양대승(Yang, Dae-Seung),김현태(Kim, Hyun-Tae),진승태(Chin, Seung-Tae),전민수(Jeon, Min-Soo) 한국체육과학회 2018 한국체육과학회지 Vol.27 No.1
This study aims to analyze the outcomes of the matches in the 2017 World Taekwondo Championships in Muju County, Korea, where revised match rules applied. To this end, scoring and deduction penalties were analyzed for different match tactics. For the purpose of this study, scoring and deduction penalties in 293 women’s matches were analyzed in relation to the game tactics for each female weight division. SPSS 19.0 was used to analyze scoring and deduction penalties according to the game tactics, through which frequency and percentage were calculated and tests were performed at the significance level of .05. The findings of this study are as follows. First, in sparring matches, scoring and deduction penalties were most frequent in matches where athletes adopted the tactics of playing on the center court. Points were obtained more frequently in the tactics dominating the center court than playing around court boundaries, and deductions were more often declared in the latter tactic than in the former. Second, in sparring matches, scoring and deduction penalties were most frequent in the third rounds on the center court. Scoring occurred most often in the third round, followed by the second and first rounds. Deductions were declared more often in the third round; their frequency in the first and second rounds was similar, albeit with some differences according to the weight division. Third, in sparring matches, scoring was most frequent when athletes were winning the match while playing on the center court, while deduction penalties were most often declared when athletes were losing the match while playing on the center court.

한민혁 ( Min Hyeok Han ),정광채 ( Gwang Che Jung ),이재봉 ( Jae Bong Lee ),김현태 ( Hyun Tae Kim ) 한국체육대학교 체육과학연구소 2014 스포츠사이언스 Vol.32 No.1
Current research is to determine vertebral form and isokinetic muscular strength of Taekwondo players who performed Taekwondo Poomsae and kyorugi exercise for a long period of time. The subjects of the research are 10 Taekwondo Poomsae, kyorugi players whose exercise experience is over 5 years and who have been registered in 2013 Daehan Taekwondo Association and 10 ordinary students of same age in K University, total 30 subjects. Vertebral form is determined with trunk imbalance, pelvis sloping, pelvis angle of torsion, spinal segment rotation angle, scoliosis, thoracic kyphosis, pre, post-lumber by using Formetric Ⅲ, Germany, the 3D image video processor. Extensibility, flexor muscle of body was determined by using CSMi(HUMAC CO., U.S.A), the isokinetic muscular strength measuring machine. As a result, Trunk Imbalance of vertebral form showed significant difference. However, Poomsae group and kyorugi group showed significant difference in Trunk 180° Extension although Poomsae group showed high level of figure in other parts without significance. As a result, kyorugi group has been proved to have vertebral form change caused by repeating laterality training and have lower muscle endurance and therefore, it is concluded that the application of vertebral reinforcement training program is required.

This study aims to compare body score followed by the proficiency of electronic protective gears in Taekwondo. For completing this goal, after targeting 1523 games in 2012-2013 spring Korean University federation Taekwondo festival, data on game records and the strength of the kick were collected. Through collected materials, the strength of the kick in 2012 and 2013 was divided yearly. Moreover, after calculating average strength of the kick and success rate of the kick, it compared and analyzed the strength of the kick in 2012 and in 2013. Besides, in order to check differences of these strengths followed by the proficiency, independent sample t test was carried out and for data processing, Excel 2010 and SPSS 18.0 were used. Followings are results of this study. Firstly, when strengths of the kick in 2012-2013 followed by weight division of men were compared, the higher strength was shown in 2013 as average 3.06 and the higher success rate of the kick was also shown in 2013 as 7.53%. Secondly, when strengths of the kick in 2012-2013 followed by weight division of women were compared, the highest strength was shown in 2013 as average 2.71 and the highest success rate of the kick was also shown in 2013 as 6.90%. Thirdly, when differences of strengths of the kick in accordance with the proficiency were proved, in all weight divisions, without light of men, feather and middle of women, there were significant differences. major findings encountered in combining results from this study. the finding indicates that the more electronic protective gears are used, the more competitor have scoring power.
