On the website r/NYYankees, a sub-forum ("subreddit") of Reddit is devoted to the Major League Baseball team New York Yankees, with its predominantly male users showing their appreciation for baseball heroes by expressing erotic desires towards the players. When a player performs well, the subreddit is filled with admiration of desires to become the player's intimate lover-explicitly expressed by "male" fans. This paper explains the phenomenon of young male fans' desire for the now-lost model of traditional masculinity of domination and control, displayed in the context of baseball players' dominant performances. The discrepancy between a fan's non-homosexual real-world self and his homoerotic language on the subreddit is explained using the "performative fandom" theory, developed by Osborne and Coombs borrowing Butler's notion of performativity. This paper suggests how this desire for traditional masculinity serves as recognition to the collapse of masculinity in the modern American society.

Purpose: The purpose of this study was to determine how a shoulder complex stabilization exercise affects ball control and ball speed in elementary school baseball players with an instable scapula. Methods: The subjects of the study were 16 baseball players attending S elementary school in Kwangju Metropolitan City. A shoulder complex stabilization exercise was conducted three times per week for one hour for four weeks. Then, the participants were divided into a scapular instability group or stability group based on their lateral scapular slide test scores. The measurement tool was measured using the target, the ball speed tester (PR1000-BC). All inspections were measured before and after the mediation period to examine the change in the subjects according to the mediation period. Results: As a result of measuring ball control, there was a statistically significant difference in the variation over time (p < 0.05), and there was no statistically significant difference in the interaction between time and group (p > 0.05). As a result of the test of effectiveness between subjects, there was no statistically significant difference found among the groups (p > 0.05). In terms of ball speed, there was no statistically significant difference found in the variation over time (p > 0.05) as well as in the interaction between time and group (p > 0.05). In terms of the effectiveness between subjects, there was no statistically significant difference found among the groups (p > 0.05). Conclusion: It was found that the shoulder complex stabilization exercise could improve ball control for elementary school baseball players. It is believed that this will help prevent and solve possible sport damages experienced during training or competitions, thereby helping athletes use training methods to improve their exercise capacity and continue their careers.

PURPOSE: The aim of this study was to identify the effects of joint mobilization intervention combined with exercise on range of motion (ROM), pain intensity, and functional performance in adolescent baseball players with internal impingement syndrome of the shoulder. METHODS: The subjects were 30 adolescent baseball players diagnosed with internal impingement. Ten subjects were randomly assigned to each of 3 groups: Group 1 (exercise only), Group 2 (joint mobilization combined with exercise), and Group 3 (rest-only control group). Three weekly interventions were given for 4 weeks (the control group rested for 4 weeks). The main outcome measures were goniometer, visual analogue scale (VAS), and Korean Kerlan Jobe shoulder-elbow (K-KJOC) scores. The ROM (external and internal rotation), pain intensity (at the moment of throwing), and functional performance were compared among the groups. RESULTS: No significant difference was observed among the groups in the range of external rotation of the shoulder before and after the intervention, but the range of internal rotation was significantly increased in Group 2 compared to Groups 1 and 3. Pain intensity was significantly lower in Group 2 than in Group 1 and 3, and functional performance was significantly increased in Group 2 compared to Group 1 and 3. CONCLUSION: An intervention that combined joint mobilization with exercise was more effective than resting or exercise alone for rapid recovery from sports injury and improvement in athletic performance.

Purpose : The purpose of this study was to suggest a more effective method by comparing the effects of changes in pain intensity, muscle strength, and athletic performance after applying a 6-week eccentric training program (ET-MWM) or concentric training program (CT-MWM) with MWM for high school baseball players with shoulder internal impingement (SII). Methods : A total of 75 participants were randomly assigned to each group and divided into two groups, "ET-MWM group (n=35)" and "CT-MWM group (n=32)" according to the intervention method. Pain intensity, muscle strength (external rotation, internal rotation), and athletic performance were first measured before the intervention, and after the intervention 3 times a week for a total of 6 weeks, both groups were re-measured in the same way. Visual analog scale (VAS) was used for pain intensity, biodex dynamometer for muscle strength (60 °/sec.), and Kerlan-Jobe orthopedic clinic shoulder & elbow score (K-KJOC) for athletic performance. Results : As a result of analyzing the homogeneity of the pre-intervention characteristics and initial measurement variables of the study subjects, there was no significant difference between the two groups in all variable values. Pain intensity (VAS) was significantly reduced in the ET-MWM group than in the CT-MWM group (p<.05). In addition, the maximum muscle strength of external rotation & internal rotation of the shoulder (60 °/sec.) and athletic performance (K-KJOC) were significantly increased in the ET-MWM group than in the CT-MWM group (p<.05). Conclusion : Compared with the CT-MWM training program, the ET-MWM training program reduced shoulder joint pain and further increased the muscle strength required for throwing motion in high school baseball players. As the result showed better athletic performance improvement, the ET-MWM training program can be clinically recommended as a more effective intervention.

본 연구는 한국프로야구리그(KBO)에서 활동하는 개별선수의 승리에 대한 기여도, 즉 생산성을 추정하는 모형의 구축을 목적으로 한다. 기존의 지표인 대체선수대비승수(WAR)의 단점인 계산방법의 복잡성을 해결하기 위하여 KBO 공식 홈페이지에서 제공하는 기록만을 이용한 계량모형을 구축함으로써 새로운 시즌의 기록만 대입하면 생산성을 생성할 수 있게 하였다. 또한, Scully(1974)와 Krautman(1999) 등 미국 메이저리그 선수의 가치추정모형이 소수의 기록에만 의존하였던 점을 개선하여 KBO가 발표하는 61개 기록을 모두 사용하여 현실에 적용할 수 있는 모형을 구축하였다. 2002-14년 팀기록의 패널 자료를 이용하여 득점 및 실점방정식을 추정하여 회귀분석에 기초한 대체선수대비승수를 추산하였다. 추정 결과, WAR과 상관계수가 타자는 0.869, 투수는 0.882로 나타나 두 지표가 비교적 유사한 것으로 나타났다. 추정 결과를 근거로 2014년 시즌 후 FA선수들의 계약 내용을 평가하면 비교적 생산성 추정치와 계약액수의 상관관계가 높아서 구단이 FA계약에서 합리적인 판단을 하고 있는 것으로 나타났다.
