PURPOSE This study aimed to verify the relationship between adolescent athletes’ julsil, competitive trait anxiety, and self-management. METHODS A total of 370 adolescent athletes who were registered with the Korean Sport & Olympic Committee participated in the survey; 24 insincere responses were excluded from the analysis, leaving a total of 346 participants. After verifying the construct validity of the measurement tool used in the survey, statistical and correlation analyses were performed. The research model was subsequently verified using structural equation modeling. RESULTS Adolescent athletes’ julsil had a significant positive effect on self-management but not on competitive trait anxiety. In addition, self-management was found to have a significant negative effect on competitive trait anxiety, and also completely mediated the relationship between julsil and competitive trait anxiety. CONCLUSIONS Adolescent athletes’ julsil does not increase competitive trait anxiety, but rather plays a role in reducing it by increasing self-management. These findings unveil mechanisms through which julsil can be used to enhance athlete performance.
PURPOSE This study comprehensively examined the aerodynamic and flight characteristics of modern soccer balls, focusing on their design evolution and performance attributes. METHODS The aerodynamic characteristics of five types of World Cup balls (2006 Germany World Cup, 2010 South Africa World Cup, 2014 Brazil World Cup, 2018 Russia World Cup, 2022 Qatar World Cup) and five types of Euro tournament balls (EURO2008, EURO2012, EURO2016, EURO2020, EURO2024) were examined, along with their respective design changes. RESULTS Through detailed analysis, significant variations in aerodynamic properties among soccer balls used in various tournaments were identified. Recent advancements have resulted in faster transitions towards critical Reynolds numbers, indicating improved stability in flight trajectories. This enhancement was attributed to the augmentation of surface roughness, which plays a crucial role in enhancing aerodynamic stability and overall performance. 2D simulations simulating powerful goalkeeper kicks revealed distinct differences in flight distances among different soccer balls; the Jabulani ball used in the 2010 World Cup exhibited the longest flight distance, while that of the 2024 Euro ball was the shortest. CONCLUSIONS Variations in surface texture significantly impact aerodynamic properties, affecting flight distance, arrival time, and height. This study underscores the significant design enhancements in modern soccer balls that optimize aerodynamic stability and performance, with modifications aimed at improving flight characteristics and enriching player experience.
PURPOSE The ethical leadership of Taekwondo instructors plays a crucial role in enhancing the value of Taekwondo. Therefore, this study explores the elements of ethical leadership among Taekwondo instructors by drawing on the insights from Lao Tzu's Tao Te Ching. METHODS Through the Tao Te Ching, an oriental classic containing the ideas of Lao Tzu, we have extracted and discussed the elements of ethical leadership that Lao Tzu conveys to Taekwondo leaders in this era. RESULTS The ethical leadership of taekwondo leaders in the Tao Te Ching was presented as the virtues of inaction and humility as behavioral norms. Inaction as a code of conduct was discussed about a leader who practices inaction in a changing world through subjective thought rather than a meaningful Taekwondo leader who leads Taekwondo with an existing pattern and looks at ethics. A Taekwondo instructor must possess the virtue of humility. A Taekwondo instructor with humility must be glazed, soft, and humble as water. CONCLUSIONS In a Taekwondo culture that follows the Confucian ideology of extreme austerity, Lao Tzu's ethic of non-action and the virtue of humility can be like wearing an ill-fitting robe. However, standing on the edge, outside the frame of reference of the ideologies and values we have come to believe in and follow, and seeing the world as it is, not as it should be, according to the laws of nature, provides a new discourse for Taekwondo philosophy.
PURPOSE This research explores the underlying mechanism that determines how people perceive their goal progress and its relation with their motivation and self-efficacy. METHODS Three hundred and sixty Koreans who participated in an online survey were given salient individual exercise goals (11 workouts), and they reported their self-efficacy, goal progress perception, and motivation. We conducted dummy variable multiple regression analysis (2 [absolute progress-low (27%) vs. high (73%)] X 2 [categorization vs. no-categorization]) and multiple moderated mediation analysis based on Process Model 7 and 21 (Hayes, 2017). RESULTS The findings showed significant interaction between categorization and absolute progress on progress perception. In low progress condition, the categorization group perceived more progress than no categorization group and contrary effect in high progress condition. For motivation, in low progress condition, categorization group was more motivated than no categorization group, and inverse effect in high progress condition. Moreover, there was no direct effect, but only low self-efficacy group played the moderating role between perceived progress and motivation in conditional indirect effect. Lastly, the result indicated significant multiple moderated mediation effect. CONCLUSIONS This research theoretically contributes to the domains of categorization and motivation. Sport marketers can utilize categorization as a strategy by breaking down yearly memberships into monthly categories based on consumers perceptions. Future research can include subsequent motivation after a superordinate goal is completed.
PURPOSE This study aimed to categorize consumers’ subjectivity on public value of citizen professional football club. METHODS Q-sample and Q-classification charts were developed based on theoretical background of the public value of citizen football clubs, and in-depth interviews with consumers were conducted using the Q-methodology. Q-classification and Q-factor analyses were conducted by selecting local residents as P-samples. RESULTS The public value of citizen football clubs was confirmed as ‘Type I: club-city win-win’, ‘Type II: social integration’, and ‘Type III: culture-led’. These types are contrary to previous studies that mainly focused on management and marketing, such as financial profitability and soundness, regional economic impact, and commercial value. This is the result of examining the public value of the citizen football club from based on the subjectivity of consumer, and it differs from that in previous studies. CONCLUSIONS This study reconfirmed the specificity and role of citizen football clubs in commercialized professional sports. It showed that citizen clubs must adopt organizational goal and operation method that are different from profit sports organizations (clubs).
PURPOSE Although sport and graffiti often collaborate in various forms and sectors, research on this phenomenon is insufficient. Therefore, this exploratory study analyzed the role of sport in line with the diffusion of graffiti in Korea. METHODS Qualitative research method was applied for data collection and analysis. Specifically, systematic literature review, semi-structured in-depth interviews, and written interviews were used for data collection. Subsequently, content analysis, categorization, and itemization were performed. RESULTS International sporting events had an impact on the diffusion process of graffiti. Additionally, graffiti was used as a promotional content for sporting events and sport brands, and specific sport content were used as the medium for street art works, including graffiti. Furthermore, graffiti was used as a promotional content for marketing activities in collaboration with a professional sports team by general corporations. CONCLUSIONS As graffiti becomes one of the major cultures from a subculture, it is expected to increase public interest in all sports and not just in specific sports through collaboration with graffiti.
PURPOSE Taekwon gymnastics is expected to be a program that can overcome the management difficulties currently faced by Taekwondo gyms and contribute to the expansion of Taekwondo base. Therefore, this study aimed to examine the relationship among organizational identification, flow experience, intention to continue participation, and recommendation intention of Taekwon gymnastics participants. METHODS In this study, data was collected from 313 teenagers participating in Taekwon gymnastics at Taekwondo gyms in the metropolitan area from September 10 to 24, 2021. A total of 267 questionnaires were selected as the final sample, and data analysis was conducted using SPSS 23.0 and AMOS 23.0. RESULTS Organizational identification had a significant effect on flow experience, challenge only had a positive effect on intention to continue participation, flow experience did not significantly affect recommendation intention, and intention to continue participation had a significant effect on recommendation intention. CONCLUSIONS The results of this study confirmed that organizational identification can contribute to improving inner pleasure and self-esteem, and it is necessary to examine the role of factors that can mediate the relationship between flow experience and behavioral intention in the future. Furthermore, managers of Taekwondo gyms should hold various events that can inspire teenagers’ sense of challenge to encourage intention to continue participation.
PURPOSE This study aimed to explore the functional movement in rope climbing. METHODS The rope climbing experiment included 16 healthy young male participants, and the methods of hand, cross-leg, and foot-hooking climbing were employed. The muscle activity and joint range of motion were measured and analyzed using EMG (Electromyography) and IMU (Inertial Measurement Unit) sensors. One-way analysis of variance was conducted (α<.05). RESULTS The activity of the forearm and biceps muscle was lower in cross-leg and foot-hooking climbing compared to hand climbing (p<.01), and the rectus femoris muscle activity in cross-leg climbing was smaller than that in hand climbing (p<.05). Furthermore, the adductor muscle activity in cross-leg climbing was higher than that of other types (p<.01). The range of motion for the elbow and shoulder flexion was smaller in hand climbing than in other types (p<.05); furthermore, the range of motion in the pelvis, thigh, and knee joint was the smallest in cross-leg climbing (p<.05). CONCLUSIONS Because the pulling muscles such as the forearm, biceps, pectoralis major, and latissimus dorsi play an important role in the entire climbing motion, it is necessary to train the upper-body pulling-muscle group along with strengthening the core and lower body muscles.
PURPOSE The purpose of this study was to understand the athletic identity of youth football players and to trace its changing trend. METHODS Participants of this study included 93 players in 2005 and 94 players in 2021, who were in middle and high schools. All participants answered open-ended questionnaires. After the results of the inductive content analysis, the changing trend of the results was assessed. RESULTS The athletic identity of youth football players were collected from 811 raw data samples collected in 2005 and 741 collected in 2021 and categorized into 19 sub-categories and 5 categories. The results show a tendency to be specific to football. The athletic identity of a football player itself is weakening, being replaced by the identity of being a student. The role of the camp is also weakening, while more privacy and autonomy are allowed to the players. As a result, efforts to secure the players’ right to study were accepted by the players, and expected to decrease as camp life with limited privacy is on the decline, and as senses toward one’s physical competence are changing. CONCLUSIONS Sociocultural contexts, including changes in the system and social modifications, are reflected in the football player's athletic identity and its changes. The athletic identity of youth football players has changed from its 2005 version of unacademic camp life with limited privacy to the 2021 version, where the player leaves camp to be provided with privacy and attend classes.
PURPOSE This study compared and analyzed the current status, system, and trend of evaluation and operation of member sports organizations of the Korean Sport & Olympic Committee from 2006 to 2020. METHODS A literature study was conducted for this study. RESULTS The 15-year evaluation was developed through three periods: preparation, execution, and construction. The preparation stage (2006–2009) was when the evaluation index development and operation system were established. The execution stage (2010–2016) is a critical time; when the current system was established. This was when evaluation perception was spread in the sports world and continuous changes such as evaluation system and operation, indicators. Finally, the construction stage (2017–2020) was when the evaluation system was established after integrating the Korean Sport & Olympic Committee and the National Sports Council. CONCLUSIONS It played a role in promoting balanced growth from organizational management to ethical management of sports organizations through preparation, execution, and construction. Further, the evaluation reflected the continuous development and change of the Korean sports community and one organizational assessment.
