PURPOSE Using GPS data from actual field hockey matches, this study examined the effects of position and substitution time on the physical performance of elite female players. METHODS From 25 matches played in 2023, data involving 26 players were collected. Players’ positions were classified as forwards (FW), midfielders (MF), and defenders (DF). Substitution times were segmented into 5, 10, and 15 minutes, respectively. A two-way ANOVA was employed to analyze movement patterns across different exercise intensities as influenced by player position and substitution time, followed by Bonferroni post-hoc tests for further detailed analysis. RESULTS Analysis revealed that both position and substitution time significantly affected exercise intensity. Notably, at a substitution time of 5 minutes, substantial differences were observed in high-intensity movements, including the distance covered at high-intensity and the frequency of high-intensity efforts. Furthermore, the substitution time’s impact was particularly pronounced among forwards and midfielders. CONCLUSIONS Findings suggest that shorter substitution times can enhance players’ active movement, thereby supporting maintenance of tactical adjustments and positively influencing overall performance. Implementing shorter substitution times could be particularly beneficial for optimizing team performance, especially for players in forward positions.
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.
PURPOSE This study aimed to present the measures necessary to perform well in tennis clubs by examining the adaptation process of the MZ generation participating in tennis clubs. METHODS A qualitative case study was performed and data was collected through in-depth interviews, direct observations, and literature surveys. The data were analyzed by applying pattern matching among the analysis methods proposed by Yin (2014), and the reliability and validity of the study were demonstrated by consultations between colleagues, reviewing members, and comparing and analyzing previous studies. The study participants were seven MZ generation tennis club participants selected through snowball sampling (one of the non-probability samples). RESULTS Achieving a level of skill that allows for compatibility and the effort required for it, the acceptance of differences in club culture and between generations, having the etiquette necessary for Generation MZ, and falling for the charm of tennis itself were identified as factors for successful participation in tennis clubs. CONCLUSIONS This study is expected to help the MZ generation, who have recently been interested in tennis, continue their participation, as well as lay a small foundation for the expansion of the base of the sport by detailing the measures necessary to successfully participate in tennis clubs.
PURPOSE This study sought to explore elementary school (ES) teachers' avoidance of teaching model-based instruction (MBI) in physical education (PE) lessons. METHODS An open-ended questionnaire (n=93) and three focus group interviews (FGI ) were conducted with seven ES teachers. The collected data were analyzed using grounded theory analysis procedures (Strauss & Corbin, 1997). RESULTS Accordingly, we derived a grounded theory paradigm model composed of the core phenomenon (ES teacher’s avoidance of MBI in PE lessons), causal conditions (traditional difficulties of Elementary PE lessons, mismatch between MBI and ES teachers/PE lessons, lack of experience and teacher knowledge for/in MBI), contextual conditions (complex instructor organization, powerful trend of play), intervening conditions (value orientation for fun-focused PE, misunderstanding about PE curriculum), interactive strategies (focus on screening physical activities, preparing for PE lessons with YouTube rather than teacher guide book), and results (learner inclusive effects and de-curricularization). CONCLUSIONS ES teachers’ avoidance of MBI in PE lessons is a result of several reported problems with elementary PE lessons and is likely to be a recurring problem in the future. To encourage ES teachers’ MBI in PE lessons, efforts should be made to build practical knowledge of model use in pre- and in-service teacher education.
PURPOSE The purpose of this study was to analyze the effect size of the unified theory of acceptance and use of technology (UTAUT) in the sports field using a meta-analysis. METHODS After identifying related studies by using RISS, 22 articles were selected and used to analyze the relationship between UTAUT sub-factors (performance expectancy [PE], effort expectancy [EE], social influence [SI], and facilitating conditions [FC]) and intention to use via the comprehensive meta-analysis program. RESULTS The results are as follows: First, the effect size between PE and intention to use was 0.521. Second, the effect size between FC and intention to use was 0.514. Third, the effect size between EE and intention to use was 0.500. Finally, the effect size between SI and intention to use was 0.475. CONCLUSIONS Diverse strategies can be derived to increase consumers' intention to use in the sports field using the UTAUT model.
PURPOSE The United Nations (UN) has proposed 17 Sustainable Development Goals and has been extending its efforts to achieve them. Sport can be linked closely to the third goal, which is related to health and well-being. Therefore, this study aimed to explore and to analyze individual's changed sport activities during the COVID-19 pandemic, focusing on ways to achieve health and well-being related goals through sport. METHODS A qualitative research method was employed, and in-depth interview methods were used for data collection. For data analysis, categorization and itemization were used along with content analysis. RESULTS Looking at the derived results, in the context of an infectious disease such COVID-19, sport activity patterns have changed due to reasons such as stadiums or facilities, interpersonal reasons, fear, inconvenience, staying healthy, increase in leisure time, and individual preferences. CONCLUSIONS Due to the COVID-19 pandemic, the indicators of health and well-being related SDGs are exhibiting a downward trend. At this point, it is necessary to find a way to achieve the goal through sport that can participate voluntarily for the purpose of pursuing pleasure.
PURPOSE This study aimed (1) to analyze the behavioral intention and use behavior among the consumers of online home training contents via YouTube by employing the unified theory of acceptance and use of technology (UTAUT); (2) to test the moderating effects of risk perception toward the coronavirus (COVID-19) infection, and 3) to test differential impacts of generational difference across millennial and baby boom generations. METHODS A total of 400 questionnaires were distributed, and 383 samples were used for the final analysis after excluding 17 incomplete responses. Data were analyzed using the SPSS 25.0 and AMOS 22.0. RESULTS It was found that (1) the performance expectancy, the effort expectancy, and the social influence had positive effects on behavioral intention; (2)the facilitating condition had negative effects on the use behavior; (3) the behavioral intention had positive impact on the use behavior. Moreover, the risk perception toward the COVID-19 infection did not have moderating impacts on the UTAUT model, whereas generational differences did. CONCLUSIONS Our results suggest that the marketing strategy that improves exercise performance, convenience, and social influencing factors may be key to home training customers' behavioral intention and use behavior. Furthermore, home training material makers should recognize that the features and infrastructure required for the two generations are distinct and develop a separate marketing strategy for each.
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 The purpose of this study was to analyze the relationship among emotional leadership, coach trust and athletic satisfaction of university. Methods 288 university soccer players were surveyed on the emotional leadership questionnaire, coach trust questionnaire and athletic satisfaction questionnaire through convenience sampling method. SPSS 23.0 and AMOS 23.0 were used to achieve the purpose of this study. Frequency analysis, confirmation factor analysis, reliability verification, correlation analysis and the structural equation model analysis were performed. Results First, emotional leadership had a positive effect on coach trust of university soccer players. Second, emotional leadership had a positive effect on athletic satisfaction of university soccer players. Third, coach trust had a positive effect on athletic satisfaction of university soccer players. Finally, coach trust mediated the relationship between emotional leadership and athletic satisfaction. Conclusions Emotional leadership was a leadership that can efficiently increase coach trust, and leaders must communicate with players through emotional effort and team operations with goals of athletic satisfaction and happiness rather than wins and losses were required.
Purpose This study focuses on accessibility to sports facilities that can be classified into structural leisure constraints. The purpose of this study is to explore exploratory analysis of the types of reservation methods and payment methods, which are the initial stages of consuming sports facilities, and to explore inconveniences that consumers feel when making reservations. Methods A quantitative research method was used to derive the results, and data were collected through a questionnaire survey method. The collected data were analyzed by technical statistics focusing on the reservation method, payment method, and inconvenience during reservation. Results As a result, it was found that the main types of reservation methods and payment methods were homepage, homepage/telephone, telephone, homepage/app, and account transfer and card payment, respectively. In the case of inconvenience, the procedure was complicated, address and location, and reservation method were identified as the main matters. Conclusions Efforts must be made to secure both the convenience and publicity of accessibility at an early stage, such as reservation methods and payment methods for sports facilities.
