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 The purpose of this study was to understand the current market trend for golf apparel rental services and to present basic data to revitalize the golf apparel rental service market and prepare continuous growth plans. METHODS The following keywords were selected for data collection: "golf wear + rental (렌탈)," "golf wear + rental (대여)," "golf apparel + rental (렌탈)," and "golf apparel + rental (대여).“ The analysis period was limited to two years and seven months from January 1, 2020 to July 31, 2022, when COVID-19 began. The analysis was focused on the top 60 keywords to simplify the network. RESULTS Various keywords were extracted through text mining, TF-IDF, connection centrality, emotional analysis, and semantic network analysis of big data analysis. These were then categorized into four factors: “golf apparel rental service,” “self-expression and authentication,” “sharing economy,” and “emotion.” CONCLUSIONS The results of this study show that young golfers are unreluctant and are generally positive in renting golf apparel. Therefore, if the growing paradigm of the consumption behavior of MZ-generation golfers is recognized and analyzed and the requirements are continuously satisfied through various strategies, there will be a higher possibility to help expand the golf apparel rental market.
PURPOSE This study aims to analyze elective courses in overseas physical education curricula and explore directions to improve the national physical education curriculum. METHODS Physical education curricula from the Ontario Ministry of Education and New South Wales Department of Education, and an administrative announcement book of the 2022 Revised Physical Education Curriculum were collected and analyzed. RESULTS The Ontario physical education curriculum offers a range of elective subjects that fit students’ need to enter universities and colleges. It also has a systematic curriculum flowchart within elective courses. The NSW physical education places importance on learning life skills and offers content-endorsed courses that comprises core studies and optional modules. CONCLUSIONS This study clarified the differences between the learning content of elective subjects and suggested the necessity of developing plans to provide students with effective course path.
PURPOSE This study aims to critically read the film <Run-Off 2> in a manner in which its narrative represents and constructs the multicultural subject as the fearful and compassionate “other,” and its structure and meanings reconciles with the concept of cultural citizenship. METHODS This research is informed by two methods: 1) text analysis by deconstructing the narrative structure and flow, and 2) contextual interpretation focussing on understanding the significance of the filmic representation in the Korean historical, political, social, and cultural contexts. RESULTS The narrative of the film portrays and constructs the multicultural subject as a cultural other, with specific styles of representation, in which stereotypical description, otherizing tropes of double process, and recognition struggle for cultural citizenship. CONCLUSIONS The study summarized the present research and laid out some suggestions for critical studies of sport films from an interdisciplinary approach and cultural studies-based methods.
PURPOSE This study aims to investigate the problems posed by the new “Health Exercise Managers” qualification system implemented in 2015 and suggest a reformation plan for the qualification definition, written test, and practical–oral test. METHODS Eleven experts working in the academia and the exercise prescription field were selected as research participants using purposive sampling method (professors=5, director of sport science division in national research and development institute=1, head of national/private organization that issue Health Exercise Managers certificates=2, and health exercise managers working at university hospitals =3). The results were collected, examined and classified following numerous discussions among the authors. RESULTS First, the qualification definition should be based on “course completion” in the short term and “department certification” in the long term. Second, the written test can be reformed by identifying the core courses related to health exercise management and merging similar or overlapped courses. Also, the grades should be calculated for each question based on the knowledge gained in related courses. Third, the practical–oral test questions should be publicly available in advance to help candidates better prepare and learn practical skills, rather than set the standards for elimination. CONCLUSIONS An overall reformation of the qualification definition, written test, and practical–oral test will solve the problems posed on the quality of the “health exercise managers” qualification system.
PURPOSE This study aimed to investigate how a 10-week online live Pilates training held during the COVID-19 pandemic affected body composition, cardiovascular function, and physical fitness in sedentary middle-aged obese women. METHODS Thirty obese women, aged 30 to 49 years (BMI : 25kg/m2 or more; waist circumference: 85cm or more) who were leading a sedentary lifestyle for more than 8 hours a day were assigned to one of two groups—that is, the Pilates training group (TR) and the control group (CON). Four participants were dropped from the study during the intervention period. Participants in the TR group (n=13) performed online live mat Pilates exercises (3 sessions per week; 60 minutes per session for 10 weeks, whereas participants in the CON group (n=13) were asked to maintain their normal lifestyles during the same intervention period. Independent variables related to body composition, cardiovascular function, venous function in the lower body, physical fitness, and 1-RM (repetition maximum) were measured at pre-test and post-test, and data were compared between the two groups and between the two tests. RESULTS 1) Regarding body composition, body weight, body mass index, fat mass, and waist circumference decreased significantly in the TR group. 2) Regarding cardiovascular function, stroke volume and cardiac output increased significantly in the TR group, and total peripheral resistance decreased significantly in the TR group. 3) Regarding venous function in the lower body, blood flow velocity and blood flow volume of the parenchyma area increased significantly in the TR group. 4) Regarding physical fitness, cardiorespiratory endurance, muscular endurance, flexibility, and balance improved significantly in the TR group. 5) 1RM of biceps curl, lat pull-down, leg curl, and leg extension increased significantly in the TR group. CONCLUSIONS It was concluded that the 10-week online live Pilates training had positive effects on the body composition, cardiovascular function, venous function in the lower body, and physical fitness of middle-aged obese women leading sedentary lifestyles.
PURPOSE This study aimed to identify movement pattern differences in the running of youth soccer players with and without lateral ankle sprain (LAS) histories. METHODS A total of 12 participants were recruited and assigned to the LAS group or the control group. All participants were assessed for anthropometric data, and they filled in the subjective ankle function questionnaires. Then, reflective markers were attached to their bodies, and they were instructed to run at the preferred speed on the 9-m runway thrice. 3D joint angles for ankle, knee, and hip joints were exported, and their mean values and 95% confidence intervals were calculated. Ensemble curve analysis was conducted to compare running kinematics between the groups. RESULTS The LAS group exhibited fewer dorsiflexion angles and more inversion angles compared to the control group. Excluding the dorsiflexion deficits and more inverted ankles, there were no significant differences between the groups. CONCLUSIONS Although the ankle kinematic patterns found in this paper are not considered LAS risk factors, it will be able to identify precise LAS risk factors with prospective design (e.g., lower extremity movement patterns) as well as intrinsic risk factors.
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 identify the lower limb muscle activity based on direction prediction presence or absence and gender during side cutting in healthy college students. METHODS The study participants included 14 healthy males and females (8 males; 6 females). All participants ran at full speed for a distance of 12m, and side-cutting was carried out at 45 degrees in a randomly indicated direction and in a fixed direction. Simultaneously, data regarding vastus medialis, vastus lateralis, semitendinosus, and biceps femoris muscle activity of the dominant leg were collected using an electromyography sensor, and data regarding vertical acceleration were collected using an inertial sensor attached to the pelvis. A sync webcam was used for obtaining the initial contact of side cutting and the stance period time. During the 10 milliseconds (pre-activation) prior to the initial contact and 50% of the stance phase (loading phase), vastus medialis, vastus lateralis, semitendinosus, and biceps femoris average muscle activity and hamstring to quadriceps ratio included as variables. RESULTS During the pre-activation and loading phase, the vastus medialis muscle activity of the male group was higher in the unexpected condition than in the expected condition. Furthermore, hamstring to quadriceps ratio was confirmed to be lower under unexpected condition compared to under expected condition during on loading phase. CONCLUSIONS The study results suggest that the risk of anterior cruciate ligament injury may increase with side cutting under unpredictable conditions. It is expected to provide useful information for identifying factors related to knee injury in the general population.
PURPOSE This study aimed to apply a capacity building program to sport life skill leaders and to provide cases of this process. METHODS The study participants included four leaders (male=2, female= 2, Mage=37.5) who were managing a sport life skills program at a university. They participated in a capacity building program, which consisted of (a) understanding (leader seminar), (b) application (managing the sport life skills program), and (c) evaluation (leader’s self-reflection), which were conducted in eight sessions. Four leaders conducted self-evaluations using program quality assessment (PQA) during every session, and quantitative and qualitative data were collected. Qualitative data were derived using a cross-case analysis, and quantitative data were used for calculating the effect size after performing the paired t-test. RESULTS Analyzing the reported cases of sport life skill leaders, the use value of the capacity building program was identified. Furthermore, the cases reported by the four leaders enabled observation of how the leader’s capabilities were strengthened. In the paired t-test, the effect size of physical and psychological safety, appropriate structure, supportive relationship, opportunities to belong, support for efficacy mattering, opportunities for life skill building, excluding integration of family, school, and community effort, were all significant. All effect sizes were found to have “very large effects.” CONCLUSIONS The capacity building program played a positive role in strengthening the leaders’ life skill coaching capabilities. These findings have practical implications—chiefly, it is important to strengthen leaders’ or coaches’ capabilities in order to foster life skill development and transfer of student-athletes.
