Purpose This study was to explore construct of fear and courage behavior overcoming the fear and relationship between fear and courage in competition. Methods Total 65 national athletes of combat sports(Judo, Boxing, Taekwondo, Fencing) responded to open questionnaire about fear and courage behavior in competition. The data was analyzed by triangle verification and content analysis. Results Firstly, the fear of combat sports athletes consisted of five factors, which were negative consequences, lack of preparation for a game, concerns of performing one’s best, expectation of significant others, and internalized ego threat. Secondly, courage behaviors to overcome fear were self-effort, self-suggestion, self-conviction, selfish self-regulation, social self-control, self-analysis, and acceptance of experience. Finally, there were the relationship between fear and courage in competition. Conclusion These results will contribute to provide useful information for combat sport athletes and coaches in different level to cope with competition fear.
The current study aimed to examine behavioral intentions of online sports products consumers using the Extended Goal-directed Behavior Model. The questionnaires were distributed to consumers who had experience of purchasing sports products online. Data collected from 282 respondents were analyzed mainly using structural equation modeling. The results were as follows: First, attitude and subjective norm had a positive effect on desire. Second, perceived behavior control did not affect desire but had a positive effect on behavior intention. Third, positive anticipated emotions had a positive effect on desire and negative anticipated emotions had a negative effect on desire. Fourth, prior knowledge did not affect desire and behavior intention. Fifth, frequency of past purchase behavior did not affect desire, but had a positive effect on behavior intention. Lastly, desire had a positive effect on behavior intention.
This study employed a sportscape model to analyze environmental impact on spectators’behavior. In addition, the loyalty construct in the sportscape model was reanalyzed based on the theoretical framework. Five hundred questionnaires were distributed to the spectators of World University Taekwondo Championship, and 418 questionnaires were used for data analyses. The analyses of measurement and structural models were conducted using SPSS 18.0 and EQS 6.2 programs. The results indicated that the measurement model showed acceptable reliability and validity. The structural analysis showed that five stadium factors (parking, cleanliness, crowding, food service, and fan control) have significant effects on spectators’ desire to stay and to revisit the stadium. Loyalty also positively affected revisit intention. This study emphasizes sport environment to make spectators revisit and provides future research suggestions to improve the sportscape model.
PURPOSE This study investigated the differences in plantar pressure distribution when using three breathing techniques during heel raises. METHODS The subjects were 29 professional dancers aged 20 to 30 years with more than 10 years of experience. Pressure distribution according to breathing method during heel raise was measured for 10 seconds while controlling the raise speed and gaze. The three breathing techniques were randomly ordered. Peak pressure, contact area and time, displacement, and absolute velocity of the center of pressure trajectory were measured using Emed®-le from Novel GMBH. Plantar pressure was analyzed by dividing it into a total of 12 areas (masks): five toes, five metatarsals, the midfoot, and the hindfoot. RESULTS Using the teeth occlusion breathing technique, the peak pressure on the first metatarsal was significantly reduced, the contact time of the second metatarsal was significantly longer, and the displacement of the center of pressure trajectory was significantly shorter. Additionally, during the phase of the forefoot retainer, the velocity of the center of pressure trajectory was significantly reduced. CONCLUSIONS The teeth occlusion technique reduces peak pressure, increases contact time and area, and decreases the displacement and velocity of the center of pressure trajectory, demonstrating an efficient method for maintaining balance in ballet movements. This technique can potentially enhance stability and prevent injuries in ballet dancers.
PURPOSE This study aimed to investigate the effects of different resistance training structures on basic physical fitness, 1-repetition maximum (1RM), and isokinetic shoulder and knee muscle functions in male college students. METHODS Forty college students were divided into four groups: control group (CG, n=10), compound set training group (CSG, n=10), pyramid set training group (PSG, n=10), and superset training group (SSG, n=10). Excluding CG, each group performed a different resistance exercise method at an intensity of 60~80% 1RM for 60~90 min, three times a week for eight weeks. To compare the effects of resistance training structures, we confirmed body composition, basic physical fitness, 1RM, as well as isokinetic shoulder and knee functions. RESULTS Results indicated that the PSG exhibited the most significant improvement in relative peak torque in isokinetic shoulder and knee testing compared to the other groups. Additionally, all exercise groups positively affected back strength, 40m sprint, and 1RM compared to the CG, although no significant differences were observed among exercise groups. CONCLUSIONS The findings suggest scientific evidence supporting the effectiveness of pyramidal resistance training in improving isokinetic shoulder and knee muscle functions in male college students.
PURPOSE This study explores injury attributions accepted by serious football participants, specifically intermediate and advanced players. METHODS Utilizing Q methodology, 25 Q-samples and 33 P-samples were selected, and Q-classification was conducted. Principal component factor analysis through the PQ method (vers. 2.35) was employed for data analysis, and types were interpreted and named based on the Q-sample with a Z-score of ±1.0 or higher. RESULTS Results categorized injury attributions accepted by the participants into four types: 'Type I: Facility/ Human Resource Responsibility Type,” 'Type II: Luck/Other Responsibility Type,” 'Type III: Self Responsibility Type,” and 'Type IV: Insufficient Safety Education.” This study provided academic and policy discussions by reclassifying four types according to their internal and external location and controllability. CONCLUSIONS In conclusion, this study emphasizes the relevance of all four types of injury attribution to policy considerations. Ensuring participants' right to participate in safe and enjoyable sports requires addressing facilities/human resources, education, and insurance as major policy components of sports safety.
Circadian rhythm (CR) is an intrinsic process that changes in a cycle of approximately 24h/day to maintain body homeostasis. It is mainly controlled by the central command through the suprachiasmatic nucleus, and modern society features can disturb the central CR, contributing to various diseases. Recent studies have provided evidence that extrinsic factors, such as regular physical activity (RPA) and timerestricted feeding (TRF), can also alter the CR peripherally, emphasizing RPA and TRF as the non-therapeutic methods for circadian misalignment (CM). Therefore, this review scrutinizes the regulatory mechanism of CR and summarizes the relationships between CM and various diseases. In addition, by reviewing studies investigating the prevention or improvement of CM via RPA and TRF, the value of circadian biology research that can directly affect health, physical function, and lifespan is summarized. By introducing the scientific evidence for RPA and TRF to maintain and improve CR, we tried to emphasize the importance of regular exercise and healthy eating habits to people in the modern world who have difficulty maintaining CR.
PURPOSE The purpose of this study was to explore violence in the Korean sports world and examine the reality of sports violence in the past and present by reflecting the voices of the field and academia through an in-depth analysis. METHODS First, through a systematic literature analysis, the essential problems of sports violence that have been discussed in academia were explored. Next, based on this, perception was explored by applying a multi-case study method to an in-depth analysis of the opinions of experts in academia and the field. Finally, by deriving the research results and discussing them, implications for this study were provided. RESULTS First, the essential problem of sports ethics was the change in sports ethics perception that was different from the sports ethics problem caused by the diversification of victoryism. Second, the essential problems of sports violence were ethics and sports ethics in society with different standards, and the unaltered perception and culture of sports ethics. Third, the problems and causes of sports violence were institutional changes and practical limitations of physical violence, control of the possibility of violence, insensitive verbal violence, cyber violence as a new form violence due to changes in the times, and rationalizations of bystanders. CONCLUSIONS This study is expected to serve as a catalyst for the field and academia by exploring the phenomenon of sports violence in more depth through the problems of violence by type and its causes according to the changing times.
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 is to investigate the human rights violations of Semi-professional team athletes. Methods The subjects of the survey were 4,069 people in total of 56 sports athletes from teams. than, 1,251 athletes who agreed to provide personal information (635 males and 616 females) were sampled. The survey tool consisted of a total of 76 questions asking about violence, sexual violence, and general characteristics of semi-professional athletes. Results were frequency analysis, cross-analysis, and multiple response analysis. Results Despite being an adult athlete in the semi-professional Team's Workplace Sports Team, life controls were severe in the sports team and human rights violations, such as verbal and physical violence, were widely observed, and sexual harassment and sexual violence were not small. The main perpetrators were the leaders and senior players, and the venue was the training ground. The players were in an environment where they were forced to respond passively for fear of hierarchical, collective atmosphere and personal disadvantages, and were blind spots for labor rights in terms of contracts and treatment. Conclusion To human rights violations of semi-professional athletes as the structural problems of the Korean sports. It is necessary to strengthen human rights education by the workplace movement department and conduct regular human rights surveys, and legal institutionalization to establish a disciplinary information system for perpetrators. In addition, by enacting guidelines for human rights in the sports world, a system should be prepared so that the victims can actively express their intentions.
