The main purpose of the study was to analyze the influences of riding horse training on Ear position, cortisol and Stress index with Thoroughbred retired racehorse. Our study included 9 Thoroughbred racehorse that had retried form horse racing. Thoroughbred retired racehorse was performed 20-50 minute a days, 5 times per weeks for 3 months. The statistical analysis was done using dependent t-test were carried out to find out if there was a significant time effect. Coping with stressors can be measured by direct procedures, including the evaluation of behavioral and physical parameters. The followings are the major findings of the analysis. First of all, The measurement on Ear position of Thoroughbred horses was significantly decreased at post retraining. Second, Cortisol level was significantly increased at post retraining and Stress Index was significantly decreased at post retraining. There are some important finding on this study. Ear Position and Stress Index was significantly decreased than Cortisol level was significantly increased after training. This result do not match expectation. Also, Cortisol level is very lower than normal range. The race period affect a Cortisol level lowered. It seem that the training session to have higher Cortisol level even though the level is not to reach at normal level. There are more further study to solve on these relationships should continue.

본 연구의 목적은 뇌성마비 아동에 대해 재활승마프로그램을 실시하고 압력 측정 장비를 이용하여 재활승마 활동 전후, 뇌성마비 아동 발바닥 압력을 측정하여 정적 및 동적 평형성에 변화를 분석하는데 있다. 재활승마프로그램이 뇌병변 장애 아동의 평형성에 미치는 영향을 분석하기 위해 평형성을 동적평형성과 정적평형성으로 구분하고 동적평형성은 Gait평형성, 정적평형성은 Stance평형성으로 구분하였다. Gait평형성의 변인은 좌·우 발압력차, 왼발 압력 중심 Jerk, 오른발 압력 중심 Jerk이고 Stance평형성의 변인은 좌·우 발압력차와 발압력 중심 Jerk를 분석 결과를 토대로 재활승마 프로그램이 뇌성마비 아동의 평형성에 미치는 영향에 대하여 논의를 하였다. 재활승마프로그램을 실시한 결과는 다음과 같다. 첫 번째로, 뇌성마비 아동들의 동적 평형성의 왼발 Jerk과 오른발 Jerk에서 8주후부터 유의한 감소를 보였다. 두번째로, 정적평형성에서는 좌우 압력차와 압력 중심의 Jerk에서 8주후부터 유의한 감소를 나타냈다. 이상의 결과로 재활승마가 뇌성마비 장애 아동의 평형성에 긍정적인 영향을 미치는 것을 알 수 있었다. 고려점으로, 뇌성마비 장애 아동의 평형성을 강화시키려면 운동 시간과 강도를 고려해야 한다. The study aimed to examine the effects of therapeutic horse riding activities to the balance of the children with cerebral palsy. The study samples were 12 children of cerebral palsy, and All males, aged 9 to 11, who have no cognition defects and self walk, have no difficulties of standing. They were participating in the therapeutic horse riding lessons. The 30 minutes duration of horse racing activities were applied to two times a week, for 16 weeks, and the horse riding activities consisted of the basic skill training, the walks and trots for the advanced skills, and game activities. To examine the effectiveness to balance before 8 weeks and after(16 weeks) the exercise, the plantar pressure of left and right foot were measured. In determining the differences between pre, mid(8wks) and post(16wks) tests, the data were analyzed by the corresponding 2 × 3 repeated measured anova within .05 significance level. The results of therapeutic riding programs are bellows. First, there is a significant decrease in the left/right foot Jerk of the dynamic balance of children with cerebral palsy after 8 weeks programs. Second, Jerk pressure and difference between left and right foot pressure were significantly decreased in children with cerebral palsy after 8 weeks therapeutic riding. These findings indicate that therapeutic riding program was effective in children with cerebral palsy to enhance balance function. In consideration, in order to enhance the balance function in cerebral palsy should take account of exercise time and intensity.

The study of subjects were 11 students majoring in Taekkyun from Y University who hold over 3 Dan. In this study, duration of the movement, distance and speed of the movement, and the angle of segments of body in their Poombarbgi and Naejireugi were analyzed through Kwon 3D XP Motion Analysis System. The average totaltime spent in the motion was 3.75 second which took 1.56 second in Poombarbgi, 1.31 second in kick and others including recovery time took 0.90 second. Result of study was not setting the height limit. The height of the kick was 62.6% of the subjects, which were relatively higher than the kicking height of abdominal region. It appears this result due to the Taekkyun competition rule that can not kick abdominal region for safely in the competition. On the impact, upper body keep the lean over backward -43.8° from Z-axis, left hip joint should keep the hyper-extension of 24°, right knee joint should be straight, left knee joint should keep the flexion of 48°, right ankle joint should keep the plantar flexion of 45.8°.

This study is to clarify similarities and differences between Dureumchiki at Taekkyon and Front-turing kick at Taekwondo by comparing kinematic variables of positions, kinetic variables of force components applied on the ground. For this, four subjects majoring in Taekwondo and another four specializing in Taekkyon were selected. Two force-plates (3,000Hz/s) and seven real-time infrared cameras (250Hz/s) were used. From these the following conclusions have been drawn after the analysis of the kinetic factors. At the take-off of the kicking leg from the ground, it took longer for Dureumchiki than for front-turning kick at Taekwondo due to the features of Gumsil Motion (springing up and down by bending and stretching knees) and kicks at Taekkyon which make opponents lose their balances by pushing. Furthermore the former showed larger displacement of the COG of the body at take-off position. Regarding the change to the movement of COG, the posture with low COG was seen at Taekkyon but the feature of big horizontal movements(y axis) from side to side(medial/lateral) was also observed. NJerk to foot segment and COG translation seen at bending-up situation of knees and stretching situation showed larger values at Taekkyon which have a significant difference from those at Taekwondo, which lead to the conclusion that the front-turing kick at Taekwondo had more efficiency than that of Taekkyon since the former come to have smaller change at the movements of segments and faster rotation-speed thanks to simpler movements than those at the latter. Kicking legs at both showed very similar force values, while the lateral force at Taekkyon was at work more than that at Taekwondo.

The main purpose of the study was to kinematic comparison of the Dureumchigi in Taekkyon, to the Face Dollyo Chagi in Taekwondo which is similar to the Dureumchigi. Eight male college athletes, 4 in Taekkyon and 4 in Taekwondo were selected as samples, and 7 sets of cameras were used with 200Hz/sec filming. For the experiment, the sample students were asked to attempt to do more than 8 times of kicks, and 4 of them were chosen to the detail analysis. Each kick was analyzed to determine the speed, angle of hip and ankle, body balance variations, and the degree of contribution, and calculated statistical significance applying the paired t-test. The major findings were as follows. First, longer time were consumed in footing than in Taekwondo, because the characteristic of the footing in Taekkyon which makes the opponent"s weight balance be destroyed, by pushing instead of Gumsil movement and hitting action. Second, in case of kicking both in Taekkyon and Taekwondo, the analysis of the angle of both ankles were all showed significant differences, and in hitting actions, the angle of hip joint, and right ankle were also significantly different. The reason of this could be, in case of Taekkyon, pushing will be the final skill to make fall down the opponent regardless any hitting point contact, and to push down the opponent with minimized injuries. Along with this characteristic, both the hip joint and right ankle were distinguishably bent not to make the impact momentum be increased. Third, in Taekkyon, the degree of contribution of sequential movement of toe action speed, were high in the spine action of trunk, thigh calf, and body weight transferring proportionately, and calf, trunk, body weight transferring, and thigh in Taekwondo. And, the differences of each sequential movement for kicking was all significant. In sum, for the purpose of kicking and Gumsil movement, the time lapse, body weight balance distribution, each joint angle, toe action speed, and the contribution of sequential body movement were all showed differently.
