Differences in Exercise Stress, Job Satisfaction, Intention to Quit Exercise, and Quality of Life According to the Psychological Abuse Experiences of Elite Male Athletes.

This study aimed to further understand psychological abuse in sports and contribute to the development of elite sports and athletes' persistent performance by identifying the causal effects of psychological abuse on elite athletes' exercise stress, job satisfaction, intention to quit exercise, and quality of life (QOL). Data were collected from 363 elite South Korean male athletes (ages ≥ 20 years) from August to September 2023. The independent variable for comparative analysis was the presence or absence of psychological abuse in elite male athletes by coaches. The participants were divided into two groups: a non-abuse-experienced group (Group 1) and an abuse-experienced group (Group 2). Participants' demographic and athletic background information (e.g., career and sport) were also collected. This study showed that the three factors (exercise stress, intention to quit exercise, and QOL) were higher in Group 2 than in Group 1. These findings provide a meaningful analysis of the impact of psychological abuse on the mental health, persistence, and overall QOL of elite male athletes that can be used to develop countermeasures and policies against psychological abuse that threatens the mental health of elite athletes.

The Relationship between Physical Activity and Health-Related Quality of Life in Korean Adults: The Eighth Korea National Health and Nutrition Examination Survey.

This study used the raw data from the Eighth Korea National Health and Nutrition Examination Survey (KNHANES-VIII), conducted under the supervision of the Ministry of Health and Welfare and the Korea Centers for Disease Control and Prevention in 2019. It was conducted to identify a significant correlation between physical activity (PA) and health-related quality of life (HR QOL) in the Korean population. In 2019, the KNHANES-VIII added the Health-related Quality of Life Instrument with 8 items (HINT-8) to assess the HR QOL. The independent variable is related to PA, specifically the presence or absence of PA, type of PA, and the frequency of PA. The dependent variable is HR QOL, measured either as the total score or specific items (e.g., pain, vitality, and memory) using the HINT-8 measurement tool. Demographic characteristics and health status may directly or indirectly influence the relationship between PA and HR QOL, which were used as covariates. A total of 4357 participants were included in the current study. The mean HINT-8 scores were significantly higher in the participants who performed PA on a weekly basis, leisure-related PA or MSPA, as compared with those who did not (p = 0.01 and <0.0001, respectively). In both the unadjusted and adjusted models, the mean HINT-8 scores were significantly higher in the participants who performed ≥500 MET-min/week of leisure-related PA as compared with those who did not (95% CI: 1.017-1.033; p < 0.001 and 95% CI: 1.005-1.02; p = 0.001, respectively). In both the unadjusted and adjusted models, the mean HINT-8 scores were significantly higher (95% CI: 1.015-1.03; p < 0.001 and 95% CI: 1.004-1.018; p = 0.003, respectively) in the participants who performed MSPA for ≥2 days/week as compared with those who did not. The current results confirmed that there is a significant positive correlation between the PA and HR QOL based on the HINT-8 scores. Because the HINT-8 was developed to assess the HR QOL in Koreans, however, further studies are warranted to evaluate its applicability to other ethnic populations.

COVID-19 Obesity: Differences in Infection Risk Perception, Obesity Stress, Depression, and Intention to Participate in Leisure Sports Based on Weight Change.

This study examined the impact of COVID-19 on individuals' weight change and mental health by analyzing differences in risk perception, obesity, stress, depression, and intention to participate in leisure sports during the COVID-19 pandemic. Data were collected in the Republic of Korea between June and August 2022. This study included 374 individuals aged ≥ 20 years who regularly participated in leisure sports. A comparative analysis subdivided the participants into two groups based on weight changes during the pandemic: weight loss and maintenance (Group 1) and weight gain (Group 2). These formed the independent variable. The dependent variables were (a) infection risk perception, (b) obesity stress, (c) depression, and (d) intention to participate in sports. The results revealed statistically significant differences between the two groups in infection risk perception, obesity stress, and depression factors, but not in the intention to participate in sports. This study demonstrated the impact of COVID-19 on weight changes and mental health. These findings can guide future quarantine strategies to control new infectious diseases and policies to prevent obesity and stress.

The Structural Relationship between Basic Psychological Needs, Grit, and the Quality of Life of Individuals with Disabilities.

Individuals with disabilities who engage in regular physical activity reduce their risk of diseases such as obesity and heart disease, as well as other risk factors; relieve tense emotions, and improve their quality of life via interaction with others. Despite these advantages, only one out of every four Koreans with a disability engages in physical activity. Grit is the ability to maintain interest and effort towards a goal in the face of adversity and failure. Grit can act as an important factor in increasing the psychological level of individuals with disabilities. We investigated the relationship between basic psychological needs, grit, and the quality of life of disabled individuals to determine if physical activities can improve their quality of life. Our dataset included 296 disabled individuals registered with the Korean Ministry of Health and Welfare. Using structural equation modelling, the direct and indirect effects of grit, quality of life, and psychological needs satisfaction such as competence, relatedness, and autonomy were examined. We found that competence positively affects consistency of interests (ß = 0.150, t = 1.854), relatedness positively affects consistency of interests (ß = 0.354, t = 4.409), and autonomy has no statistically significant effects (ß = 0.101, t = 1.086). Second, competence positively affects perseverance of effort (ß = 0.249, t = 3.206), autonomy negatively affects perseverance of effort (ß = -0.269, t = -2.880), and relatedness has no statistically significant effects (ß = -0.017, t = -0.249). Third, autonomy positively affects quality of life (ß = 0.214, t = 2.349) while competence and relatedness had no statistically significant effects (ß = -0.018, t = -0.208; ß = 0.096, t = 1.288). Fourth, consistency of interests positively affects quality of life (ß = 0.312, t = 4.191) while perseverance of effort had no statistically significant effects (ß = -0.094, t = -1.480). Fifth, competence was found to have positive indirect effects on quality of life through grit. This study underscores the importance of addressing these three basic psychological needs and elements of grit when designing future quality of life interventions for disabled individuals.

A Gap between Relaxation of Government Quarantine Policy and Perceptions of COVID-19 among the General Public in Sports: Focusing on Vaccination Status.

Although an increasing number of people are getting vaccinated for COVID-19 and quarantine policies are easing owing to fatigue from high-intensity social distancing, people's fear remains. This study attempted to determine the appropriateness of quarantine policies that are gradually easing by comparing and analyzing sports participation and respiratory infection perception recognized by sports participants according to vaccination status. Data were collected from 302 ordinary Korean citizens aged 20 or older for three months from November 2021 in the Republic of Korea. From the survey respondents, data on the main factors of this study included (a) demographic information, (b) vaccination, (c) loyalty in sports, (d) behavioral intention to participate in sports, (e) infection anxiety from others, and (f) risk perception of COVID-19. As a result, the survey respondents, subdivided into an unvaccinated group (Group 1) and a vaccinated group (Group 2), derived statistically significant results on sports participation and respiratory infection perception. Specifically, survey participants who had completed all secondary vaccinations showed a relatively higher (a) loyalty in sport (M = 3.789), (b) behavioral intention for participation in sport (M = 4.056), and (c) infection anxiety from others (M = 3.548), but showed a relatively lower (a) risk perception of COVID-19 (sensitivity) (M = 3.494). The results of this study could be utilized as valuable data to minimize the gap between the relaxation of government quarantine policy and perceptions of COVID-19 among the general public in sports, which have not yet been clarified.
