This study was aimed at providing practical information to improve Korean adolescents’ wellness by empirically identifying its correlation with sports participation and having an internal health locus of control (IHLC) during the COVID-19 pandemic. This study comprised both a pilot test and a main study. We recruited 844 Korean adolescents as subjects in January 2021 to participate in an online self-reported survey. The reliability and validity of the scales used (sports participation, IHLC, and wellness) were verified through a pilot test. In the main study, we verified the differences between all variables according to adolescents’ demographic characteristics and the structural relationship of sports participation, IHLC, and wellness. Sports participation had a positive effect on IHLC (p < 0.001) and wellness (p < 0.001). Additionally, IHLC had a positive effect on wellness (p < 0.001). In juvenile educational institutions, there is a need to develop strategies to increase wellness, sports participation, and IHLC among adolescent students, which can improve their wellness in the context of the COVID-19 pandemic.

This study aimed to examine the relationships between sports participation, optimism/pessimism, self-regulation, and coronavirus-related stress in Korean adolescents during the pandemic situation. Specifically, we attempted to offer valuable information that could help to alleviate coronavirus-related stress in adolescents by promoting participation in sports and the development of optimism and self-regulation. To achieve this aim, we conducted an online survey of 836 Korean adolescents in the pilot and main studies. Confirmatory factor, frequency, path, reliability, descriptive statistical, and multimedia analyses were performed. Our findings indicated several differences for each variable according to demographic characteristics. Sports participation exerted a positive effect on optimism (p < 0.001) and self-regulation (p < 0.01) and negative effects on coronavirus-related stress (p < 0.05) and pessimism (p < 0.001). In addition, optimism exerted a positive effect on self-regulation (p < 0.001) and a negative effect on coronavirus-related stress (p < 0.001), while pessimism exerted a negative effect on self-regulation (p < 0.01) and a positive effect on coronavirus-related stress (p < 0.001). Further analysis indicated that self-regulation had a negative effect on coronavirus-related stress (p < 0.05). These findings highlight the need for youth educational institutions to encourage adolescents to participate in sports and for organizing bodies to suggest various policies and provide education that can assist them in properly coping with and overcoming coronavirus-related stress by strengthening their optimistic attitude and self-regulation ability.

Background: We aimed to verify the structural relationship between sports participation, ego-resilience, and healthpromoting behavior of Korean adolescents in a pandemic situation. Methods: In Nov 2020, an online survey was conducted with 751 adolescents in Korea. The data obtained through the survey were analyzed in several ways, including frequency, reliability, confirmatory factor, descriptive statistical, and path analyses. Results: Sports participation had a positive effect on ego-resilience and health-promoting behavior, while egoresilience has a positive effect on health-promoting behavior. Overall, sports participation directly affects healthpromoting behavior and that an indirect effect occurs through ego-resilience. Conclusion: Educational institutions such as schools and the Korea Offices of Education should devise various measures so that adolescents growing up in a global pandemic situation can strengthen their health-promoting behavior by securing ego-resilience through participation in various sports.
