Abstract
This study aimed to investigate the effects of resistance sprint training on anaerobic energy metabolism and power output in adolescent track sprinters. Sixteen adolescent sprinters were randomly assigned to either the RST group (n=8) or the sprint interval training (SIT) group (n=8). Over an 8-week period, both groups trained three times per week. The RST group performed resisted sprints with a sled (20% body mass resistance, maximal effort 80m sprints, 3 repetitions, 2 sets, with static rest), while the SIT group performed maximal effort 80m sprints, 3 repetitions, 2 sets, with dynamic rest. Pre- and post-training measurements included body composition, a 100m sprint test, energy system contribution analysis, blood tests (LDH isoenzyme, Creatine kinase), and anaerobic power. The results showed that in the RST group, glycolytic energy system contribution and average power significantly increased post-training compared to pre-training, and 100m sprint time, LDH-1, and LDH-4 significantly decreased. In the SIT group, LDH-4 significantly increased post-training compared to pre-training. There were no significant changes in peak power, LDH-2, LDH-3, LDH-5, and Creatine kinase in either group. Therefore, 8 weeks of RST can be considered a useful training method for improving performance by increasing the glycolytic contribution and maintaining average power during a 100m sprint, leading to a decrease in 100m sprint time.

Abstract
The purpose of this study was to analyze the sustainability of the club as a profit-generating company and to explore a plan for the development of domestic professional baseball clubs based on this. Nine of ten professional baseball clubs in Korea, excluding the Samsung Lions, were selected for analysis, and the Altman Score, which is widely used as a method of measuring corporate insolvency risk, was adopted. The Altman Score calculation formula was implemented using Excel after obtaining their financial statements registered in the Financial Supervisory Service’s Data Analysis, Retrieval and Transfer System to calculate the Altman Score. The analysis period was set from 2018 to 2023, and the analysis period was divided into pre-COVID-19 (2018-2019), COVID-19 spread (2020-2021), and post-COVID-19 (2022-2023) to examine the changes in the Altman Score before and after COVID-19. The results of the study are as follows. First, as a result of the trend analysis of the Altman score, the risk of insolvency increased as the Altman score fell significantly during the spread of COVID-19(2020-2021), but the Altman score improved in 2022 and 2023, recovering to the level before the spread of COVID-19(2018-2019). Second, as a result of the Altman score judgment analysis, the Kiwoom Heroes and the LG Twins clubs have successfully overcome the COVID-19 period and improved their sustainability significantly compared to before COVID-19. Third, depending on the Altman score calculation method, there may be a difference in the judgment result of insolvency risk, and in common, profit generation using team’s assets is an important factor in increasing or decreasing the Altman score. Based on the derived research results, a plan for the development of the professional baseball clubs were presented.

Abstract
Recent consumers have increasingly prioritized environmental friendliness, sustainability, social responsibility, and transparent governance in their purchasing decisions, prompting many sports brands to lead in ESG (Environmental, Social, and Governance) management. This study aimed to analyze the impact of sports brands’ ESG management activities on perceived corporate image, price fairness, and purchase intention, providing both academic and practical implications. Frequency analysis, confirmatory factor analysis, reliability analysis, correlation analysis, and structural equation modeling were conducted using SPSS and AMOS programs. The results revealed that: first, only environmental activities among sports brands’ ESG management activities had a statistically significant positive impact on purchase intention; second, all ESG management activities (environmental, social responsibility, and governance) positively influenced corporate image; third, only environmental activities and governance structures had a positive impact on perceived price fairness; fourth, the corporate image formed through sports brands’ ESG management activities positively affected perceived price fairness; fifth, the perceived corporate image positively influenced purchase intention; and sixth, the perceived price fairness positively impacted purchase intention. These findings suggest that sports brands’ ESG management activities are not merely trend-following but represent core values for sustainable development, enhancing corporate image and increasing consumer purchase intention.

Abstract
Even the best sports policies can become ineffective without public understanding, participation, and support. Therefore, sports administration organizations require successful public relations strategies that transparently communicate policy content and information to the public and effectively gather feedback to drive policy implementation. This study aims to develop strategies for public relations in sports administration organizations. To achieve this goal, we utilized the research procedures of Lucia & Lepsinger(1999) and Spencer & Spencer(1993), which include a literature review, interviews, focus group interviews, and content validity verification. Through this approach, we identified a total of 32 final factors across three domains. In the area of press relations, we identified factors such as the use of numbers and statistics in press materials, efforts to establish rapport with journalists, the application of Integrated Marketing Communications (IMC) strategies, and the use of positive language during interviews. For social relations, important factors include making materials engaging and interesting and selecting media that fit the promotional objectives. In the domain of event relations, key factors involve effective communication and cooperation with numerous stakeholders during events. These findings offer a comprehensive framework to enhance the promotional effectiveness of sports administration organizations.

Abstract
This study focuses on the recruitment and retention of football referees, comparing and analyzing the referee development systems of advanced football associations in England, the United States, and Australia. The aim of the research is to derive policy implications for the development of referees by the Korea Football Association (KFA) based on these findings. To achieve this objective, a literature review was conducted, including websites, reports, media releases, policy documents from national and regional football associations, and domestic and international research papers. The multiple-case study method proposed by Hague et al. (1998) was applied, and the comparison and analysis of the three countries were carried out following the procedure suggested by Park and Han (2011). Based on the similarities and differences among the three countries, three policy implications for the KFA’s referee development were proposed: first, expanding referee recruitment through online education; second, preventing attrition through a special protection campaign for new referees; and third, discovering and recruiting referee talent through educational programs for elementary and middle school students. This study is expected to provide practical assistance to the KFA in preventing budget waste during the recruitment and training process caused by referee attrition, ultimately leading to the establishment of a stable referee human resource management system.
