Team Cohesion in Individual/Team Sports Athletes: Transformational Leadership and the Role of Social norms.

Team cohesion is a critical factor in sports, yet few studies have comparatively analyzed individual and team sport athletes in sporting situations. The purpose of this study was to identify the relationship between transformational leadership, social norms, and team cohesion, and to analyze the moderating effects of individual/team sports athletes. In 2022, a total of 196 baseball, judo, soccer, taekwondo, and hockey players registered with the Korean Sport & Olympic Committee completed a questionnaire using transformational leadership, social norms, and team cohesion scales. Transformational leadership had a significant positive effect on social norms and team cohesion. Social norms had a significant positive effect on team cohesion. Transformational leadership and the interaction of individual/team sports athletes had a significant effect on team cohesion. At this time, individual sports athletes appeared to have somewhat higher team cohesion. This study sheds light on the social norms and team cohesion of athletes from a social moral perspective based on transformational leadership theory. It can also help young athletes who are just starting out to learn the culture and sociology of sports.

Wellness Perception of South Korean Elementary School Students during the COVID-19 Endemic.

This study aimed to analyze health management awareness among South Korean elementary school students in COVID-19 endemic areas. METHODS: Using convenience sampling, 675 South Korean elementary school students (age 11-12 years old) were selected as participants in July 2023. Data for the study were collected via online and offline surveys between July and August 2023. The collected data were subjected to frequency, reliability, and multicollinearity analyses, independent sample t-tests, and importance-performance analysis (IPA). RESULTS: The findings indicated the following: (1) There was no significant difference in health management performance between male and female children. (2) Children who had not experienced COVID-19 infection, had a higher level of "hygiene management" performance. (3) Among children who did not wear masks during physical activity, "mental health management" and "physical activity management" performance were higher, while "hygiene management" performance was lower. (4) The IPA matrix analysis revealed that, compared to the COVID-19 pandemic period, "physical activity management", "dietary habit management", and "sleep management" still required improvement, while "hygiene management" and "disease management" appeared to have decreased due to the relaxation of epidemic control efforts. CONCLUSION: As per the study's findings, schools, local communities, and families should make efforts to develop and implement preventive and individualized health management programs that consider the individual characteristics of their children.

Changes in Alienation in Physical Education Classes, School Happiness, and Expectations of a Future Healthy Life after the COVID-19 Pandemic in Korean Adolescents.

This study aims to investigate the changes in the structural relationship between alienation in physical education (PE) classes, school happiness, and future healthy life expectations in Korean adolescents after the COVID-19 pandemic. The data were collected from Korean adolescents using different scales. The collected data were analyzed using frequency analysis, reliability analysis, validity analysis, independent t test, and path analysis. The key results were: First, there were partial changes in each of the parameters since the outbreak of COVID-19. Second, before the pandemic, alienation in PE classes negatively affected school happiness, and school happiness positively affected expectations of a future healthy life; however, alienation in PE classes did not affect the expectations of a future healthy life, showing a complete mediating effect. Third, during the pandemic, alienation in PE classes negatively affected school happiness, and school happiness positively affected the expectations of a future healthy life; alienation in PE classes negatively affected the expectations of a future healthy life, showing a partial mediating effect. These findings emphasize the importance and potential of school education, especially PE, in promoting happiness and healthy lives in adolescents. We expect these findings to have practical implications for future research by presenting theoretical and empirical data.

Comparison of Health Awareness in South Korean Middle School Students According to Type of Online Physical Education Classes during the COVID-19 Pandemic.

Coronavirus disease 2019 popularized online classes to prevent educational deficits affected by the pandemic. This study aimed to assess the differences in the importance and performance of health awareness in Korean middle school students according to the types of online physical education classes they attended during the coronavirus disease 2019 pandemic. Overall, 583 participants were selected using a convenience sampling method; the data were obtained through an online survey using Google forms. Frequency analysis, reliability analysis, independent sample t-test, and importance-performance analysis were performed. First, the differences between importance and performance were found to be the most for sleep and physical activity management, and the least for disease and hygiene management. In addition, both groups demonstrated higher importance and performance for hygiene and disease management. There were significant differences in the importance and performance of all the sub-factors. Second, hygiene, disease management, and mental health management were found in quadrant I in both groups, while physical activity, sleep, and dietary habit management were in quadrant III. No factors were in quadrants II and IV. Correspondingly, there was no significant difference in adolescents' health awareness between the assignment-based online group and interactive online group.
