본 연구는 2004년 아테네올림픽에 출전하는 우리나라 선수와 경쟁이 예상되는 외국의 우수 선수 과거 영상 자료를 활용하여 운동역학적 분석을 실시하고, 그 결과를 경기에 활용토록 함으로써 경기력을 높이고 메달 획득에 기여하는데 목적이 있다. 분석내용은 아카이브시스템을 이용한 과거 영상 자료의 동영상 파일 구축, 경쟁선수들의 주요 기술 및 경기운영 특성 분석, 대응 전술 개발 및 올림픽 경기 사례분석이다. 연구대상은 출전권을 획득한 우리나라 레슬링 선수 8명(그레코로만형 4명, 자유형 4명)과 경쟁선수 74명이다. 우리나라선수의 체력, 심리, 기술적 특성과 경쟁선수의 기술적 특성을 도출하고, 경쟁선수 개인별로 대응전술을 개발하였다. 올림픽대회에 나타난 경기 내용을 대응전술과 관련지어 서술함으로써 대응전술의 효과 분석을 대신하였다. 연구과정에서 파생된 동영상 자료는 우리나라 선수들이 경쟁선수에 대한 특성을 인식하고 기억하는 영상 자료로 활용되었으며, 분석내용은 선수 및 지도자가 사전에 훈련 자료로 활용할 수 있는 기회를 제공하는 한편, 실제 훈련의 목표 설정에도 기여하였다. 그리고 경쟁선수의 기술적 특성이 경기에서 나타난 점, 이를 적절히 활용하여 경기를 유리하게 전개할 수 있는 가능성을 보여준 점에서 본 연구가 현장의 선수 및 지도자에게 유용하게 사용될 수 있는 것으로 사료된다. 그러나 이러한 연구가 좀더 계량적인 분석 방법을 사용하고, 객관적인 비교·평가를 통하여 더욱 학술적이고 체계화 되는 방향으로 발전되기를 기대한다. Using Akaiv system, video tapes on 74 foreign wrestling athletes (competitors) were converted to moving picture-files, and classified - summarized according to the weight categories and individuals. Their skill-characteristics were analyzed biomechanically. And physical, mental and skill characteristics of 8 Korea national representative wrestling athletes were analyzed using old data and informations from wrestling specialists and coaches. The skill-characteristics of foreign competitors were used as background to extract competing strategies for our team. The strategies were focused to overcome the competitors in the games, and finally to get gold medal in 2004 Athens Olympic Games. The files and DB on those were used to study and memory the skill-characteristics of foreign competitors for our team. And the skill-characteristics of foreign competitors were used to check the aim of daily training. Despite of the lack of scientific and systematic structures, this study was useful in wrestling training fields. That is based on that skill characteristics of foreign competitors were appeared several times in Olympic Games and that the descriptions have possibilities to make the games more winning sides by using more effectively and aggressively. But quantitative analyses and objective criteria will make the research more advanced and usefully.

이 연구는 2011 대구세계육상선수권대회 남자 장대높이뛰기경기에 참가한 선수의 경기기록 차이가 기술의 운동학적 변인과 어떻게 연계되는 가를 알아보기 위해 수행하였다. 결선에 진출한 8명(G1)과 예선경기 최하위 기록을 보인 7명(G2)이 각자의 최고기록을 낸 시기를 대상으로 2차원, 3차원 영상분석을 실시하였다. 5대의 비디오카메라를 사용하여 60 Hz로 영상자료를 수집하고, 디지타이징하였다. Butterworth 2차 저역통과 필터(차단주파수 10 Hz)를 사용하여 원자료를 평활하고 운동학적 변인을 산출한 후, 두 집단의 독립표본 차이검정을 실시하였다. 분석 결과, 조주 단계에서는 스텝 수와 11-6 m 조주구간의 수평 속도가 G1이 G2보다높다. 도약 단계에서는 G1이 G2보다 수평속도 감속이 적으며, 도약각도(바에 접근하는 각도)가 적어 전체적으로 G2보다 먼 지점에서 낮게 도약하는 기술적 특성을 보인다. 장대 구부리기 및 펴기 단계에서는 G1이 G2보다 수평속도가 대체적으로 높으며, 수직속도는 장대를 곧게 펴는 구간과 장대를 놓는 순간에 월등히 높기때문에 G1이 높이 도약할 수 있었던 것으로 사료된다. The purpose of the study was to investigate the relationship between the different kinematical variables with respect to the records and techniques performed by the participants during the 2011 Daegu IAAF World Championships Men``s Pole Vault Event. Subjects chosen for the study were 8 male athletes who were selected for men’s pole vault finals (highly skilled group) and 7 athletes who scored lowest record (skilled group) from the men’s pole vault qualifying round. Personal best record of the each subjects were chosen to perform two dimensional (2D) and three dimensional (3D) video analyses. The data were obtained at 60 Hz with the use of five video cameras and digitizing was performed. Kinematical variables were calculated after smoothing the data using 2nd order Low-Pass Butterworth filter at cut-off frequency of 10 Hz and Independent samples t-test was performed to test any differences between two subject groups. The results: during the run-up stage, the horizontal velocity rate of the number of steps and run-up phase was obtained higher in highly skilled group than skilled group. During the take-off phase, deceleration in the horizontal velocity rate was observed in highly skilled group than skilled group. Distinct technical characteristics of distant and lower take-off of the take-off angle (angle of pole support) were also observed in highly skilled group than skilled group. During the pole bending and releasing phase, horizontal velocity was generally higher in highly skilled group than skilled group. It is considered that highly skilled group was able to jump higher as the vertical velocity during the pole bending as well as release phase was much higher in comparison to the skilled group.

The purpose of this study was to perform the kinematic analyses of the men`s pole vault skills in IAAF World Championships Daegu 2011. Subjects were the 1st through 8th place finishers in the pole vault. The kinematic analyses were divided into four phases: two dimensional run up analysis, and three dimensional analyses for the remaining plant, swing up, and extension phases. Run-up variables consisted of run up distance, number of steps, average step length, the ratio of step length to his height, average velocity at the final 6~11 m, approach position. Three variables were analyzed during plant: pole angle, center of gravity (COG) velocity, and takeoff angle of COG. Swing up phase variables included: pole flexion angle, COG velocity (horizontal, vertical, resultant), COG trajectory and bar approach angle of COG. Compared to the 2009 World Championships in Berlin, the average vault height, run up velocity and approach position increased. However, horizontal velocity during the last two steps of the final approach decreased dramatically compared to speeds from 1990. These results reflect the change in both technique and improved physical fitness in pole vaulters. During extension, the peak height of COG averaged 0.3m higher then COG height when the pole was released. These specific results can help coaches and athletes modify training and improve performance.

본 연구의 목적은 길이, 둘레, 무게 요인 등 인체측정학적 변인이 지면반력의 수직 성분과 관련된 수동, 능동적 힘 요인에 미치는 영향을 규명하는데 있다. 50명의 여자 대학생을 대상으로 인체측정학적 요인과 조깅 시 지면반력을 11회 반복 측정하여 운동역학적 변인을 구하였다. 길이, 둘레, 무게 변인 중 수직 지면반력에 미치는 기여도를 회귀 분석을 통해 추정한 결과 길이 요인 가운데 수동적, 능동적 힘은 하지장의 길이가, 최대값과 부하율은 신장이 더 많은 영향력을 보이며, 하지장이 길수록 수동적, 능동적 힘이 증가하는 경향을 알 수 있었다. 둘레 요인은 능동적 지면반력 요인보다는 수동적 요인에 많은 영향을 주며, 3가지 둘레 요인이 대부분 수동적 수직 지면반력 요인에 유의한 영향을 주는 요인으로 작용하였다. 무게 요인 가운데 전신의 질량이 증가하면, 충격력과 능동적 힘에 관련된 요인들이 증가하는 반면, 근육량과 체지방량은 그 값이 증가할수록 감소하는 일정한 형태를 보였다. 또한, 무게 요인은 수동적, 능동적 정점보다는 수동적, 능동적 역적에 매우 유의한 영향을 주는 변인으로 작용함을 알 수 있었다. Fifty female students repeated 11 trials across a force platform by jogging. Force data were collected on-line at 1,000 Hz and analyzed for the magnitude and temporal characteristics of vertical ground reaction force (G.R.F.). Multiple regression analysis was used to study the relationship between the magnitude of these kinetic data and anthropometric data for their size & volume taken from measurement of the subjects. The results support the general conclusion that anthropometric variables are significant effectors of the magnitude of vertical ground reaction force. The coefficient of determination of circumference variable is most and length variable is least among 3 anthropometric variables. And circumference variable affects passive parts of vertical ground reaction force rather than active ones. In addition mass variable shows very significant in the two impulses rather than two peak forces.

Swing up phase variables included: pole flection angle, COG velocity (horizontal, vertical, resultant), COG trajectory and bar approach angle of COG. Compared to the 2009 World Championships in Berlin, the average vault height increased, while run up velocity and approach position were almost unchanged. However, horizontal velocity during the last two steps of the final approach decreased noticeably compared to speeds from 1990. These results reflect the change in both technique and physical fitness in pole vaulters. During extension, the peak height of COG surpassed the clearance height by an average of 0.11m. These specific results can help coaches and athletes modify training and improve performance.

본 연구는 레슬링 경기규칙이 개정됨에 따라 한 경기를 통해 발생되는 점수와 체급별 특성의 차이를 규명하는데 목적을 두었다. 점수에 관련된 요소에는 한 경기당 평균 득ㆍ실점의 크기, 경기형태별 득ㆍ실점 크기, 기술 종류별 득ㆍ실점 발생빈도, 파테르 공수 발생빈도 및 성공률, 점수 발생시간대별 빈도가 포함되었다. 연구대상은 2014, 2015 세계레슬링선수권대회 그레코로만형 경기 59, 66, 75 Kg급에 참가하여 5위까지 입상한 6 선수의 영상자료다. 경기내용을 정량화시키기 위하여 경기분석표를 만들고, TV 모니터를 통해 여러 차례 시청하면서 분석하였다. 5 가지 계량적 요소에 대하여 체급 간의 차이를 분석하였다. 연구결과, 평균득점은 체급별 차이가 없었지만, 평균 실점은 유의한 차이가 나타났다(p<.05). 평균 득점은 체급과 경기형태 두 변인의 교호작용에 따라 유의한(p<.05) 차이를 보였고, 실점은 체급(p<.05)과 경기형태(p<.01)에 따라 유의한 차이를 보였다. 점수를 발생시킨 기술의 종류는 체급에 따라 유의한 차이를 보였다(p<.001). 파테르 공수 성공률과 점수 발생 시간대는 체급별로 유의한 차이가 없었다. 이상의 결과를 통하여 레슬링 그레코로만형 경기의 득ㆍ실점은 경기형태와 그 기술종류에 따라 차이를 보인다. 따라서 점수가 많이 발생하는 경기형태 및 기술을 강화시키는 훈련 프로그램을 체급별로 개발하여 적용하는 것이 경기력 향상에 도움이 될 것이다. The purpose of this study was to investigate the level of factors associated with points and the difference among weight categories after the revision of wrestling competition rules from video images. Factors associated with points were average point per a game, average points according to playing type, the occurring frequency of point according to the skills, the frequency and successful ratio of Parter, and the time zone of points occurred. The video contents were concerned on athletes ranked in 1 - 5 (6 person) at 59, 66, 75 Kg categories of Greco-Roman style in the 2014, 2015 World Wrestling Championship. The analysis was done by watching TV monitor several times. Five quantitative factors were tested between weight categories. As the results, no significant difference was found in average obtained point, but significant difference was found in average lost point (p<.05). Average obtained point showed significant difference in cross effect of the type of game and weight category. And average lost point showed significant difference in the type of game (p<.01) and weight category (p<.05), too. The frequency of point by skills of stand and ground wrestling showed significant difference in weight category (p<.001). However, no significant difference was found in frequency of point by time zone among weight categories. In conclusion, the point obtained and lost and the frequency of it are associated with the type of game and skills included in it of Greco-Roman style wrestling. New training program focused on enforcing the correct type of game and skills in it might be useful for developing the performance.

The purpose of this study was to examine whether the percent body fat was related to the level of physical fitness in Korean men. The subjects were men aged between 19 and 64 years (n = 2,419) who participated National Fitness Award in Korea between May 2012 and October 2012. They were divided into 3 groups: those with <20% body fat, 20-25% body fat, and >25% body fat. The physical fitness tests consisted of grip strength, sit-ups, a progressive aerobic cardiovascular endurance run (PACER), sit-and-reach, shuttle run, and standing long jump. The inter-group differences in physical fitness level were analyzed by one-way analysis of variance via Tukey post-hoc test. The results indicated that compared to the <20% body fat group, the 20-25% body fat group (overweight group) and >25% body fat group (obese group) had a lower fitness level as judged by grip strength, sit-ups, the PACER, sit-and-reach, shuttle run, and standing long jump (p<.05). We concluded that among adult Korean men, fitness level was lower in those with a higher percentage of body fat than in those with lower percentage of body fat.

The purpose of this study was to find the relationship between standing posture biomechanics and physical fitness in the elderly. Physical fitness variables and postural variables for 227 (140 women and 87 men) elderly individuals were tested. Physical fitness tests (Korean Institute of Sports Science, 2012) included 3m sit, walk, and return, grip test, 30 second chair sit and stand, sit and reach, figure 8 walks, and 2 minute stationary march. Postural biomechanics variables included resting calcaneal stance position (RCSP), shoulder slope, pelvic slope, knee flexion angle, leg length difference, thoracic angle, and upper body slope. In statistical analysis, multiple regression was conducted by using stepwise selection method via SAS (version 9.2). Analysis for both men and women revealed significant relationships between physical fitness and age, upper body slope, knee flexion angle, leg length difference. Pelvic and thoracic angle were only related to figure 8 walking and sit and reach in women, while RCSP and shoulder slope had no relationship with any physical fitness variables.
