Purpose The purpose of this study was to investigate the differences in physique and physical fitness according to maturity between primary and middle school baseball players. Methods Participants were 112 elite youth baseball players (49 primary school; 63 middle school). Skeletal age estimated maturity. Physique (height, arm span, thigh volume), body composition (weight, muscle mass and body fat), physical fitness (strength, power, agility, flexibility, coordination, anaerobic power and aerobic power) were measured. An independent sample t-test was used to conduct verify the difference between physique and physical fitness according to maturity. Results The results of analyzing physical and physical fitness according to maturity showed that there was a significant difference (p<.05) between the early maturation group and on-time group in primary school baseball players, body fat percentage, muscle mass percentage, sit-up, anaerobic power and reaction time. There was a significant difference between the early maturation group and the on-time group in the middle school baseball players, weight (p<.05), thigh volume (p<.05), fat mass (p<.05), muscle strength (p<.01), power (p<.05) and coordination (p<.05). Conclusions In conclusion, the maturity of a growing baseball player may be influenced by the performance, so maturity status should be considered when judging the performance of a growing baseball player, especially a middle school baseball player.
Purpose The purpose of this study was to explore the process of participation in the PEAK program of collegiate athletes based on grounded theory. Methods In-depth interviews were conducted with 12 athletes from Y University who were registered in Korea Taekwondo Association. The collected data were analyzed by using the open coding, axis coding, and selective coding of the grounded theory, completed the paradigm model among the extracted concepts, and extracted the core categories through the story outline. Results As the result of data analysis, 'participating in the PEAK program' was found as the central phenomenon, and the causal situation was 'bad attitude in class' and 'helpless daily life'. The contextual conditions were 'recognition of the need for class participation and dual career' and 'motivation to participate in the program', and the intervening conditions were 'factors that hinder participation in the program' and 'factors that help program participation'. The action/interaction strategies were ‘caring climate’ and ‘promoting transfer’, and depending on the consequence, ‘learning attitude change’ and ‘life skill change’ appeared. Conclusion Participants improved their learning attitude through the PEAK program and confirmed the possibility of life skills transfer. It is hoped that this study can lead to implementation of various studies and discussions about life skills and transfer.
Purpose The purpose of this narrative inquiry was to explore the educational meaning of managing a specialist physical education school (SPES) and to suggest policy supports.

Qualitative content analysis was used to analyze the instructors’ perception regarding instructional contents. Results of this study showed that sports instructors responded to the contents as thoughtful experience (1) making myself realize the value of opponent, (2) making myself realize the value of sports, (3) making myself realize the value of judge, (4) making myself realize the value of coach/athlete. This study concluded that instructional contents was touching and emotional. Implication of instructional contents for teaching and learning sportsmanship, pros and cons of the contents and teaching tips were discussed.
PURPOSE This study aimed to explore the re-socialization process of college soccer players who rejoin college soccer clubs after dropping out. METHODS A case study approach was employed, and participants were selected using the snowball sampling method. Data were collected through in-depth interviews, participant observation, and literature reviews. The authenticity of the data was validated through triangulation, member checking, and peer debriefing. All research procedures were conducted following approval from the institutional review board. RESULTS The study revealed several key findings. First, participants faced numerous challenges during the re-socialization process into sports, including interpersonal, academic, and emotional difficulties. Second, distinctive features of the re-socialization process emerged, including the determination and effort required for adapting to university life, support from socialization agents within the university, and rapid re-socialization following dropout. Third, experiences within collegiate soccer clubs indicated low barriers to entry for former athletes, academic success through complementary relationships, a hierarchical culture familiar to student-athletes, and enhanced satisfaction in interpersonal relationships and a sense of belonging. CONCLUSIONS This study underscores the importance of institutional support that enables college athletes to participate in sports clubs, facilitating the successful re-socialization of athletes who have dropped out.
This study aimed to examine the change of the indices in blood gas, ions, and by-products of fatigue substances and components in collegiate elite Kumdo competitors, who carry out a number of competitive games during one day tournament event. Subjects were carried out total 6 simulated, but followed same conditions and rules of actual competition, with providing similar inter-game break time. Eight well trained male competitors, who had awarded from national wide competitions, voluntarily participated in this study and revealed 51.5(±8.8) mL·kg-1min-1 of maximal oxygen consumption and 12.4(±5.1) % body fat. TWOWAY ANOVA (tournament round vs. pre & post each game) was adopted to test whether the mean differences were existed, and the interaction between individual factors and main effect within each factors were analyzed. Statistical significance was set at Alpha (α) = .05. While there were no significant changes in blood hydrogen ion concentration (i.e., pH) and partial pressure of oxygen (PO2), partial pressure of carbon dioxide (PCO2) significantly decreased as the tournament games were repeated. The level of hemoglobin and hematocrit were significantly elevated only during the 1st round of tournament. Na+ was significantly increased but K+ was decreased. Ca2+ concentration however, was not significantly altered. Although the changes of blood glucose level did not show any consistent patterns, free fatty acid (FFA) concentration was increased after completed each game compared to prior to initiate the each game. Blood NH3, lactic acid, and uric acid concentration increased at immediately after each game, and the pattern was maintained throughout the tournament round continued. These results reflected that the repeated participation of the tournament may cause the accumulation of the by-products of fatigue substances in blood and alteration of various ion components and energy substrates. Accordingly, the ways of reducing the physical fatigue and providing adequate energy source inter-tournament games needs to be necessarily considered for successful Kumdo competition. Data obtained from this study could valuable for searching the effective training and management methods to improve the performance and reduce the fatigue of the professional elite Kumdo competitors.

Purpose : The purpose of this study was to investigate coaching information with which coaches provided players during badminton competition. Methods : To this end, we generated an open-ended questions and presented it to 88 high school athletes registered in the Badminton Korea Association. The survey was conducted during a tournament and immediately after the tournament to collect the data. The collected data were categorized through inductive content analysis. Results : As a result of this study, a total of 480 raw data points collected through the open-ended survey were categorized into four general areas: psychological information, technical information, tactical information, and game operation information. Specifically, psychological information was divided into six subdivisions: concentration, confidence, relaxation/stabilization, mental toughness, play thought, and passion; technical information was broken into four subdivisions: strokes, footwork, swing and posture, and position preparation; tactical information had four subdivisions: coping to opponents, play changes, rotation, and manipulation of opponents; and, game operation information was divided into two subdivisions: taking the lead in a game and changing atmosphere. Conclusions : In other words, in badminton competition, the coaches strengthened psychological skills that promote psychological stability to attain the athletes’ peak performance and modified the athletes’ motion into the action necessary for achieving accurate techniques. Furthermore, they provided a variety of coaching information so that the athletes will respond appropriately to their opponents’ play, take the lead in games and induce a positive mood. The psychological, technical, tactical and game operation information offered by badminton coaches are the main factors influencing the performance of badminton players and suggest a need for the proper management and control of the coaches as well as athletes for the peak performance.
