This study selected 10 university football male players and repeatedly treated them as sports massage group, exercise resumption group, and stability resumption. After maximum exercise, when sport massage, exercise resumption, and stability resumption were applied during recovery, blood lactic acid concentration and $LDH_5$ isozyme concentration were examined. Finally this study obtains the following conclusion 1. There was a significant difference in both lactic acid concentration and time between groups. Besides, the cross-action on group and time was significant. 2. There was a significant difference in both $LDH_5$ concentration and time between groups. Besides, the cross-action on group and time was significant. Based on the above findings, this study suggests that sport massage resumption and exercise resumption remove blood lactic acid more quickly than stability resumption to promote recovery. That means that sport massage and exercise resumption anre very effective for lowering the level of fatigue. Thus sport massage or exercise resumption treatment is considered to have a very positive effect on player's quick recovery and it should be used aggressively in a field.

This study multi-dimensionally analyzes a sport documentary, All or Nothing: Manchester City, which is an original content on Prime Video, an American Over-The-Top (OTT) platform. Due to the success of South Korean soccer player Heung-min Son who plays Tottenham Hotspur of England, the popularity of the English Premier league is recently the greatest in South Korea along with the fact that soccer has been a popular sport for a long time. This study focuses on the success of the soccer club, Manchester City, which has become a rising star with its huge investment from United Arab Emirates; Manchester City won the league four times since 1992/1993 season. Also, during the 2017/2018 season, the background the documentary, Manchester City won the league title with new records, which shows the greatness of Manchester City. Especially, this study examines the documentary by 1) Story 2) Type of Scene 3) How to watch. Thus, this study explores not only the aspects of team-themed sport documentary that shows how and why Manchester City is excellent, but also the traits of the original content that explores the structure of the media platform.

The purpose of this study was to evaluate performance characteristics in the success of team attack during volleyball game. Three dimensional analysis was performed with games of business teams. Analyzed variables were followed by the movement distance of a setter when A-quick was occurred, the position during the spike, the possibility area during the attack, the right and left distance of the assistance attacker, the distance between attacker and blocker, and the distance between blockers each others. 1. It is recommended that the movement distance of the setter be decreased in order to make stable set condition. 2. In order to make one person blocking, the formation was to be consisted of the right and left formation which was associated with the progressive attack performance of the assistance attacker. 3. It is useful to widen attack area. Also it is necessary to improve the enhancement of passing the ball against the blocking of an opponent player. Finally, it is necessary to develop kinematic variables to evaluate performance characteristics of players. Further study may consider the best defense position against the attack of the opponent player.

Korean traditional martial arts Taekkyon has a unique stepping method, Poombalbki. The purpose of this study was to investigate kinematic factors and ground reaction forces on two types of Poombalbki, one of which use knee bending and the other use chiefly hip bending. Six male taekkyoners who are the students of Y University participated in this study. Positions and velocities of CoM, the elapsed times of each phase, angles and angular velocities of low limb joints, and GRFs were analyzed for this study. The results were as follows; CoMs of whole body, trunk, and head were more posteriorly positioned in performing hip bending Poombalbki than knee bending one. Horizontal velocities of those were slower in performing hip bending Poombalbki. A player stayed more shortly within range of his opponent in performing hip bending Poombalbki. The vertical and horizontal components of GRF of forward-stepping foot were smaller in performing hip bending Poombalbki(p<.05). In conclusion hip bending is useful strategy, because A player is farther from his opponent, he stayed more shortly within range of his opponent, and the smaller weight is loaded on his front foot in performing hip bending Poombalbki than knee bending one.

Purpose : The purpose of this study is a research on the evaluation about shoulder joint function. Methods : It's based on the reference books. Result : Shoulder joint has the biggest ROM in human body, and it is a joint that stability and mobility are required at the same time sport art. Especially, function of shoulder joint than other what item players of more important overhead item correct diagnosis and evaluation for shoulder joint injury require. Measurement equipment for shoulder joint is helping a lot of incorrect diagnosis and analysis about shoulder joint function of overhead players through a lot of developments. Conclusion : I think a lot of helps torture in motor ability elevation of players and player protection as analysis by special quality in item of overhead players.

본 연구의 목적은 다운증후군 아동들의 T-ball 스윙 중에 작용하는 근육의 활동을 규명하는 것이다. 다운증후군을 가진 남자 아동 5명을 대상으로 T-ball 스윙 중에 중요하게 작용하는 pectoralis major, upper serratus, lat dorsi, anterior deltoid, rhomboids, infraspinatus, posterior deltoid의 근육활동을 노락슨 8채널 무선 근전도 측정시스템을 사용하여 시작-백스윙, 백스윙-임팩트, 임팩트-팔로스루 구간으로 나누어 분석하였다. 다운증후군 아동들은 정상아동 및 성인선수들보다 시작-백스윙 구간 및 백스윙-임팩트 구간에서 오른쪽 및 왼쪽 상체 부위의 근육활동이 더 두드러지게 나타났다. 반면에 임팩트-팔로스루 구간에서는 정상아동 및 성인선수들에 비해 더 적은 근육활동이 나타났다. 특히 임팩트 후 팔로스루 구간에서 어깨 수평 내전근인 pectoralis major와 견갑골 외전 및 상방 회전근인 upper serratus 근육의 활동 강화가 필요한 것으로 나타났다.

본 연구는 테니스 한손과 양손 백핸드 스트로크 동작에서 하지관절 움직임의 차이를 확인하여 유형별 특성을 밝히는데 그 목적이 있으며 그 결과는 다음과 같다. 볼의 속도를 결정하는 중요한 요인인 라켓헤드의 합성 속도는 양손 백핸드 스트로크 동작이 한손보다 빠른 속도를 나타냈다. 양손 백핸드 스트로크는 하체의 움직임을 최소화시키고 몸통 회전을 통한 스트로크를 하는 반면 한손 백핸드 스트로크는 몸통을 이용한 스트로크를 하기 보다는 공을 쫓아가듯이 스트로크 하는 것으로 나타났다. 슬관절의 신전모멘트는 한손 백핸드 스트로크가 큰 것으로 나타났지만, 내번모멘트와 회내모멘트 그리고 굴곡모멘트는 양손 스트로크에서 크게 나타났다. 고관절의 경우 신전, 내번, 회내 모멘트가 양손 백핸드 스트로크가 한손 보다 모두 큰 것으로 나타났는데 특히 내번모멘트의 경우 큰 차이를 나타난 반면, 외번모멘트는 한손 백핸드 스트로크가 큰 것으로 나타났다.

This study is to analyze the kinematic variables of inward $1{\frac{1}{2}}$ somersault in platform diver. For the manner, 3 people form the national diving team in the year 2000were chosen as the subjects and two S-VHS video cameras set in 60frames/sec were used for recording their motions. Coordinated raw positions data through digitizing are smoothing by butter-worth's low-pass filterin method at a cut off frequency 6.0Hz. and the direct linear transformation(DLT) method was employed to obtain 3-D position coordinates. The conclusions were as follows. However, horizontal distance which is the change of the COG, form the point of the jump to the point of Event 3 where the player is out of the board range completely, Subject B showed 105.1cm and 71.1cm of the vertical distance which are shorter horizontal distance and higher vertical distance, thus, took a great advantage of the position to prepare for the entry. Therefore, if a player takes higher position by speeding up the vertical velocity at the moment of the jumping off the board, and stays in the air longer, the player can have more time to show his skill. Because of the use of the characteristics of the inward somersault, keeping the safe distance form the board is important but in order to higher the completeness, it is ideal to keep the horizontal distance little over 100cm. Also, the angles of shoulder and elbow from Event 1 to 4, depending on swing of the arms, motions in the air, getting ready for the entry, showed some difference individual by individual, according to the velocity of the thigh and shank showed much difference while getting ready and take-off, and it's because of the individual's different bending and straightening for horizontal and vertical distance.

Pure anterior bilateral shoulder dislocations are rare clinical features, especially in traumatic forms. They are most often posterior, occurring during an epileptic seizure. Few cases are described in the literature, and the mechanism varies from case to case. We report a specific case of pure bilateral anterior shoulder dislocation in a 29-year-old judo player following an accident during his training and discuss the circumstances, mechanism, treatment, and prognosis.
