PURPOSE The purpose of this study was to synthetically explore different communication strategy patterns that are dependent on the events and stakeholders, which include professional sports players, teams, and the associations. METHODS Using the Python program, we performed web crawling and machine learning algorithms to analyze news articles for our research analyses. In particular, 696 articles on driving under the influence (DUI) of alcohol were gathered and subject to descriptive scrutiny; a total of 782 sentences were selected for the analysis. Also, among the 509 articles on illegal gambling, 484 sentences were analyzed. Moreover, 50 frequently reported words were extracted from these sentences to assess their frequencies through the word cloud method for concrete visualization. Then, the data were mapped in order to systemically understand the communication strategy patterns for each case, which were dependent on the stakeholders and timing of the event. RESULTS The empirical results revealed that in case of unethical events of driving under the influence that were reported in the news, most of the subjects chose an apology strategy immediately, but for illegal gambling reports, the parties involved rarely respond and it was difficult to find specific strategy patterns among the subjects. CONCLUSIONS The present study reveals that when professional sports teams were exposed to transgression, depending on the characteristics of the event and stakeholders, they chose different communication strategies involving fan characteristics for the event and subjects. Ultimately, they chose different strategies dependent on their fans’ involvement.
PURPOSE This study aimed to examine the associations between accelerometer-measured physical activity and both cardiometabolic disease risk factors and metabolic syndrome in Korean adults. METHODS We performed a retrospective cohort study with age-sex matched case-control using data from the 2014-2016 Korea National Health and Nutrition Examination Survey, which was administered to South Korean adults (n=320). Individuals were categorized into quartiles based on accelerometer-measured moderate-to-vigorous physical activity (MVPA). Demographic and physical characteristics, waist circumference, visceral adiposity index, blood pressure, lipid profiles, and TG/HDL-C were observed. The associations between MVPA status and cardiometabolic disease risk factors as well as metabolic syndrome were determined using multiple logistic regression. RESULTS For the waist circumference, SBP, DBP, MBP, visceral adiposity, triglyceride, and a surrogate estimate of insulin resistance, the Q1 and Q2 groups had higher means compared with the Q3 and Q4 groups. HDL-C was higher in the Q3 and Q4 groups compared to the Q1 and Q2 groups. Odds ratios for cardiometabolic disease risk factors and metabolic syndrome decreased in a curvilinear manner with the increasing quartile of MVPA. CONCLUSIONS Adults with higher MVPA participation were strongly associated with cardiometabolic disease risk factors and metabolic syndrome.
PURPOSE This study aimed to empirically investigate the influence relationships between the ESG activities of professional sports teams and sports fans’ team recognition, team preference, self-determination, and voluntary action intention. METHODS From March 1, 2022, to May 31, 2022, a survey was conducted online and offline to secure 253 copies of the final valid study samples. Descriptive statistics, frequency analysis, correlation analysis, reliability analysis, confirmatory factor analysis, and structural equation model analysis were performed using SPSS 24.0 and AMOS 18.0. RESULTS First, it was found that ESG activities in professional sports teams had a positive effect on sports fans’ team recognition, team preference, self-determination, and voluntary action intention. Second, the team recognition and team preference of sports fans of a given professional sports team had a positive effect on their self-determination and voluntary action intention. CONCLUSIONS The study results showed that ESG activities must be enjoyed not only by a given club’s sports fans but also by its stakeholders. The results suggest that gaining empathy regarding sports fans increases awareness and preference, which can lead to long-term and deeply positive effects on self-determination and voluntary action intentionl.
PURPOSE This study aimed to a) develop suitable screening tools for identifying gambling severity in Korea and b) explore factors that affect the gambling severity index in order to prevent Korean sports betting users from easily falling into gambling addiction, thus providing practical and useful guidelines in this regard. METHODS This study examined Korean sports fans who had experiences of participating in sports betting (Sports Toto), a legal sports betting system in Korea. Toward this end, an online survey was conducted from May 10 to June 25, 2022. A total of 214 questionnaire results, excluding 23 who gave insincere and/or incomplete answers, were analyzed for normal distribution through skewness and kurtosis, and subscale scores were calculated after performing exploratory factor analysis and reliability analysis using Cronbach’s α. RESULTS A psychological gambling severity index and behavioral gambling severity index were developed based on a stepwise regression analysis, which was conducted using the demographic characteristics of domestic sports betting participants and their lifestyle habits (e.g., smoking and drinking, problem gambling severity index, self-control scale, and gambling expectation scale). CONCLUSIONS First, factors affecting the psychological gambling severity index were identified (having a job, job stability, and security) along with lifestyle habits (smoking and drinking). Second, gender, occupational characteristics, full-time employment, confidence in self-control, and desire for self-improvement were indicated as significant factors that influenced the behavioral gambling severity index.
PURPOSE Sport pedagogy (SP) has established itself as a subdiscipline in Human Movement Studies since the 1970s. It has become an academic labyrinth as a result of its rapid flourishing. Most researchers are extremely confused about this disorderly research complex. This study aimed to evaluate the characteristics of SP in stages in the western (mostly English speaking) countries. METHODS Analysis of literature published in English from 1990 to 2022. RESULTS The developmental versions were divided as follows: SP1.0 is positivistic in nature, SP2.0 is multi-paradigmatic as it includes all paradigms, and SP3.0 (current version). Many academic journals have been launched, and a variety of books on divergent topics are being published. Currently, research has exploded. In SP3.0, research performed by British scholars are notable in terms of number and quality, overpowering those by scholars in the USA and other countries. Youth sport and sport coaching are regarded as new legitimate areas. Additionally, signs for SP4.0 have been indicated. CONCLUSIONS In order to find way outs in the SP labyrinth, it is necessary to recognize the current research trends in international SP.
PURPOSE This study investigated the effect of non-linear periodization strength training on basic and professional fitness of national cross-country skiers. METHODS The body composition (height, weight, BMI, body fat %), basic physical strength (grip strength, lung capacity), anaerobic power (peak power, average power), graded exercise test (maximum heart rate, running time, VO2max, lactic acid), isokinetic strength (trunk strength), and 1RM (bench press, dead-lift, squat, shoulder press, leg curl, bicep curl, cable triceps extension) of nine national cross-country skiers (male: 5, female: 4) were measured. All analyses were performed using SPSS 25.0, Kruskal-Wallis H tests were applied to observe the changes by training methods. Mann-Whitney U tests were used as Post Hoc. RESULTS The results indicated that running time and VO2max post-test improved compared to that for the pre-test for graded exercise test. The lumbar extension strength of the post-test was higher than that for pre-test. There was no significant difference in other variables. CONCLUSIONS It is suggested that nonlinear periodization strength training can be expected to improve running time, VO2max, and trunk strength for cross-country athletes; however, it does not affect the overall changes.
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 The purpose of this study was to establish the criteria for measuring acute muscle fatigue using tensiomyography (TMG) by quantifying the trend of changes in TMG variables. METHODS Searches were conducted in the Web of Science and Pubmed databases using the keyword “Tensiomyography”. Sixteen studies which used TMG to measure acute muscle fatigue caused by acute exercises in rectus femoris or biceps femoris were included. All statistical data analyses were performed using Comprehensive Meta-Analysis software program. RESULTS The meta-analysis results indicated that the biceps femoris showed a significant (p<.05) decrease in all TMG variables of the elite athletes. Also, in the overall effects of maximum displacement and mean velocity until 90% Dm (Vc90) showed a significant (p<.05) decreasing trend. The rectus femoris showed a significant (p<.05) decreasing trend for maximum displacement (Dm) in the average person, while contraction time (Tc) showed a decreasing trend in elite athletes and overall. CONCLUSIONS These results suggest that TMG could be used as an indicator of muscle fatigue indicator, and will help to develop a more proper protocol to test the response of the body to muscle fatigue.
PURPOSE This study aimed to verify the accuracy of three-dimensional (3D) motion data produced through artificial intelligence-based user motion recognition technology with images obtained using a smartphone monocular camera. This was done to explore the possibility of developing an application that can improve the reliability of the measurement of physical activity performing motions and feedback provision. METHODS To check the accuracy of the artificial intelligence-based 3D motion analysis system that utilized a semi-supervised learning method, a commercialized 3D infrared motion analysis system measured and compared motions on three movement planes, motions with limited joint movement, and fast motions in a wide moving range. RESULTS The motions on the coronal and sagittal planes produced through the 3D motion analysis application showed very high measurement accuracy; however, the accuracy of the measurement of motions on the horizontal plane, which could not be measured directly with a camera, was relatively lower than that of the coronal and sagittal planes. Accuracy in measuring 3D motion was moderate in moving motions and low in motions with limited joint movement. CONCLUSIONS For the developed 3D motion analysis system to be used in online physical education, the types of physical activities included in the program should be comprehensively composed through the analysis of the content system of the physical education curriculum and the resultant physical activities.
PURPOSE This study aimed to develop a positive psychological intervention program for a college ice hockey team and test its effects based on application to the team. METHODS The demands of 78 college ice hockey players were asked through open questionnaires. Collected results underwent integrated analysis to develop the desired program through the participants who were also observers of the team. The objectives of the program were established, and an appropriate program was developed based on the analyzed data, expert opinion, and precedent research. The developed program was applied to 26 players of a college ice hockey team to verify its effects. Tasks included writing experience reports and in-depth interviews. The Happiness Measures 1, Strength Knowledge, and Team Interaction Questionnaires were also administered. Collected qualitative data were categorized to follow inductive analysis procedures, while paired t-tests were performed for quantitative data using SPSS 25.0. RESULTS To improve the application of the program in real situations and maintain credibility and validity, the program was developed based on analyses of individual and team demands, methods of the participant as an observer, expert opinion, and other considerations. Statistically meaningful differences in positive psychological mind, happiness, recognition and utilization of strengths, team interactions, team cohesion, and so on were found using paired t-tests comparing data before and after the developed positive psychological intervention program. CONCLUSIONS Providing opportunities to recognize individual and team strengths and have valuable experiences for each player could enhance interactions between teammates and create a favorable team environment.
