손명성,신성휴 성균관대학교 2000 스포츠과학논집 Vol.5 No.-

The purpose of this study was to prove the moment of force and to evaluate the mechanical power of lower extremity during walking. The volunteers for this study were 6 male adult who have nomal foot. Each subject walked at the velocity of 2m/s with barefoot. They were videotaped using two video cameras with the frame rate being 30 Hz. This data was then reduced to 3D coordinates using the DLT method. Ground reaction force was obtained using a force plateform. Inverse dynamics were performed on these data to get the moment of force and power. It was concluded that ; 1. Moment of force the lower extremity higher showed at heel takeoff in walking, extensor of thigh major work in take off and thigh of flexiors or supinators of shank in support. 2. Mechanical power of lower extremity in walking is higher in support. Power of thigh is higher than shank and foot in take-off. Thigh performed major work in take-off and power of shank to increse in support.

손명성,신성휴 성균관대학교 2001 스포츠과학논집 Vol.6 No.-

The purpose of this study mas to investigate the characteristics of the ground reaction force of the public shoe and to offer the based on data of make public shoe for reduction of fatigue and prevention of injury. The three male adult who have normal foot participated for this study. The subjects have on E company of public shoe and the comparative B company of special shoe. The ground reaction force data collected from equipment AMTI(lpt type No.4161) during from contact of heel of left foot to taking off of the toe. Collection of frequency was 100Hz. Three trial average value used for counting of vertical ground of reaction force and total impulse. All variables divide to weight of subjects for normalization It was concluded that: The characteristics ground of reaction force appear to fast of maximal impulse have on public shoe than taken of special shoe. As a shock of lower limp will effect the muscle fatigue and occur injury. It is need that reforming a material and construction of public shoe. Therefore future study need the precision data producted that used to motion analysis system and electromiogram. So my suggestion is development of korean type last for public shoe.

The purpose of this study was to prove the force and to evaluate the contribution of lower extremity during running. The volunteers for this study were 6 male adult who have normal foot. Each subject ran at 4m/s with barefoot. They were videotaped using two video cameras with the frame rate being 30Hz. this data was then reduced to 3D coordinates using the DLT method. Ground reaction force was obtained using a force plateform. Inverse dynamics were performed on these data to get the moment of force and power. It was concluded that ; 1. Moment of force the lower extremity higher showed at heel support in running. Extensor of thigh major work in take-off and action of higher flexor than extensor. 2. Total mechanical energy was found to become higher at support and that showed especially high figure with thigh, it may be said that thigh plays a core role in the lower extremity. 3. Mechanical power of lower extremity of running is higher of both case of take-off and support. Power of thigh than shank and foot in take-off. thigh performed major work in take-off and power of shank got increased in support. 4. With regard to the contribution of lower extremity in take-off, it proved that thigh plays the more important role than shank and foot in running. the role of foot was evaluated more a few.

운동역학 : 걷기시 하지의 힘의 특성과 일률의 평가

손명성(SonMyoung-Sung) 한국체육학회 2000 한국체육학회지 Vol.39 No.2

본 연구의 목적은 걷기시 하지관절에 대한 힘의 모멘트를 산출하고 하지 각 분절의 일률을 평가하는 것이다. 연구 대상은 성인 남자 6명으로 2m/s의 속도에서 맨발로 수행하였다. 걷기 동작을 분석하기 위하여 두 대의 비디오 카메라(60㎐)를 사용하여 촬영하였다. 3차원 좌표값은 DLT방식을 이용한 KWON3D분석프로그램을 이용하여 산출하였다. 반력은 지면반력기를 사용하여 측정하였고 동작분석과 동조하여 힘의 모멘트와 일률을 산출하였다. 그 결과 근모멘트는 뒤꿈치 이지시가 착지시 보다 크게 발생하였고 역학적 일률은 이지시가 착지시 보다 높게 나타나 이지시 보다 착지시 많은 일을 수행한 것으로 나타났다. 대퇴의 일률이 하퇴와 발에 비하여 높게 나타나 대퇴가 중추적으로 일을 수행하였으며 착지시에는 하퇴의 일률이 증가하는 것으로 나타났다. 하지의 총일률에 대한 각 분절의 일률비는 대퇴가 다른 분절에 비하여 높게 나타나 걷기 운동을 주도하는 것으로 나타났다. 뒤꿈치 착지와 이지시 발과 하퇴의 일률 비가 증가하여 지지시에는 발과 하퇴의 역할이 증가하는 것으로 평가되었다. The purpose of this study was to prove the moment of force and to evaluate the mechanical power of lower extremity during walking. The volunteers for this study were 6 male adult who have nomal foot. Each subject walked at the velocity of 2 m/s with barefoot. They were videotaped using two video cameras with the frame rate being 60 ㎐. This data was then reduced to 3D coordinates using the DLT method. Ground reaction force was obtained using a force platform. Inverse dynamics were performed on these data to get the moment of force and power.It was concluded that ;1. Moment of force the lower extremity higher showed at heel take-off in walking, extensor of thigh major work in take-off and lead to of flexors or supinators of shank in support.2. Mechanical power of lower extremity in walking is higher in support. Power of thigh is higher than shank and foot in take-off. Thigh performed major work in take-off and power of shank to increas in support.3. The ratio of total mechanical power of the lower extremity to power of each segment showed thigh is higher than shank and foot. With regard to the contribution of lower extermity in take-off, it proved that thigh plays the more important role than shank and foot in walking.

This study has been aimed to analyze UCHIMATE technique of Judo gymnastically. The following are the results and the proposition obtained through an image analysis method 3 men half heavy weight champions of the national Judo standing team(85-95kg) were used as subjects for the study. 1. CONCLUSION The following are the conclusion obtained through the discussion of analysis results of the Uchimata technique using 3 men, half heavy weight(85-95kg) champions of the National standing Judo team. 1) The time performing total technique were 1.48-seconds which was performinglonger than the light heavy weight class of 1.28-seconds by 0.20-seconds, this showed that the heavy weight class players demonstrated the technique later than the light heavy weight class palyers. 2) The average length of moving 1-step leg for attacking was 24.27cm, and 2-step leg moving was 92.87cm on average. Therefore, the shorter the moving distance, the more the technique performing hour could be shortened. 3) In the hanging phase, the moving displacement of the center of gravity of the body weight showed in horizontal, vertical, right and left direction 28.97cm, 21.59cm and 13.57cm respectively. Each of which were longer than the phase of KUZUSHI and TSUKURI. Such results show that the center of gravity of the body in move lift the opponent. This reducing the displacement of body weight from the center toward the right and left direction in the phase of KAKE is considered to be effective in demonstrationg the technique. 4)The central speed of the body was 0.8cm per second on average and the average vertical speed was 0.74cm per second. The speed of right and left movement was 0.51cm per second on average which showed the horizontal speed was the fastest while it is preferred that the vertical speed should be faster than that of the horizontal. 5) Angle of the Trunk showed 98.13 ˚ on average in the hanging phase and the larger the trunk angle, the shorter the needed time to demonstrate the technique, thus making the throw of the opponent over shoulder more advantageous. 2. PROPOSTION The following propositions are suggested through this analysis for further study : 1) It is to be considered that the kinetics in hanging the thigh and the degree of every segment of the body be studied in a more detailed fashion. 2) A study on the technique of thigh hanging in an actual game situation (rather than during mere exercises) is necessary. 3) It is necessary to study the TORI and UKE techniques together. 4) The study of each weight class ought to be performed.
