Objective: The purpose of this study was to analyze the differences in kinematic factors according to stretching treatment, myofascial release treatment, and static stretching treatment conditions during squat. Method: Twelve males with resistance training experience participated in this study. Participants performed squats without treatment (Pre-Test), and performed squats after treatment with the myofascial release technique (MRT) and static stretching (SS) on different days (post-test). Squat movements were captured using eight motion capture cameras (sampling rate: 250 Hz), and the peak joint angles of the ankle, knee, hip, and pelvis were calculated for each direction. One-way repeated ANOVA and Bonferroni post hoc analyses using SPSS 27 (IBM Corp. Armonk NY, USA) were used to compare the peak joint angle of the lower extremity joints and pelvis among the normal condition (squat without treatment), MRT condition (squat after MRT treatment) and SS condition (squat after static stretching). The statistical significance level was set at .05. Results: It was observed that the maximum ankle joint flexion angle during squats was statistically reduced under conditions of myofascial release and static stretching (p<.05), in comparison to the scenario where no stretching was performed. Furthermore, static stretching was found to enhance the maximum hip flexion angle during squat (p<.05), whereas the myofascial release stretching technique resulted in the minimal posterior pelvic tilt angle (p<.05). Conclusion: Employing myofascial release stretching as a preparatory exercise proved to be more efficacious in maintaining body stability throughout the execution of high-intensity squat movements by effectively managing the posterior tilt of the pelvis, as opposed to foregoing stretching or engaging in static stretching.

The purpose of this study was to develop a competency model by career type by designing the specified career paths through the analysis of career experience of the athletes in the professional sports field. For this purpose, career types were identified as sports administrators, judges, leaders, sports information analysts, and global sports talents based on literature analysis, career development type and path guide design, experts interviews. Competency candidates were derived from interviews and workshops on experts. In order to finalize the competency model, it was confirmed by completing the feasibility test of experts. As a result, it is divided into common competency, professional competency, and global professional competency. There are 6 common competencies such as global competence, OA utilization, 29 special competencies by 5 career types, and 2 global competencies like sports foreign affairs, job preparation for international sports organization and the sports league federation. Competency definitions and behavioral indicator were developed for all competencies and could be used to diagnose the competency level of sports talents and to establish career development academy programs based on the competency model.

The development of online content is changing the value of society very diversely and rapidly. In particular, the non-face-to-face e-sports industry is growing significantly in the current situation where the COVID-19 Pandemic has not been completely overcome. The use of NFT in the eSports industry is receiving positive reviews as a field with high potential for future growth that protects digital assets of eSports users, but at the same time, it is raising concerns that cash transactions of digital items could encourage gambling. In this study, the characteristics of the recent eSports industry and NFT were identified and classified through case studies using literature, official sites, and online news articles. Through various cases of eSports and NFT, we discussed the potential for future growth and activation plan of the NFT industry of eSports. The result is as follows. First, it is necessary to use NFT using IP of eSports event itself. Second, it is necessary to combine the functional role of the item with NFT to provide features that users can utilize. Third, it is necessary to provide users with opportunities to engage in economic activities using eSports and NFT. Finally, it is necessary to use NFT to strengthen the digital asset protection of eSports users. Through this study, it is expected to be used as a basis for further discussions on the NFT industry of e-sports and as a material for securing competitiveness.

To get over it, sports market players are exploring various new markets such as online fan services and online sales. Therefore, this study proposed a way to manage the authenticity of sports-related products. The block structure, system flow, and network model were designed and prototypes were developed accordingly. Experts were invited through the derived method to conduct a target group interview (FGI) to evaluate the reliability and stability of the transaction process, the reliability and stability of payment, the tracking of accidents, and the reliability and stability of the system. Through this study, consumers can have reliability when trading sports-related products such as goods, favorite items, and sign balls.
