Background: The policy of the Physical Education (PE) Entrance Examination for Senior High School (PEESHS) is an operable and measurable educational policy proposed by the Chinese government to solve the youth’s physical health problems and promote health in middle school students. In recent years, the reform of PEESHS policy has brought youth sports to a new climax, and determining how to achieve the maximum benefit of health promotion with the PEESHS policy is the current focus of the Chinese government, society, schools, and families. The primary purpose was to investigate the health promotion benefits of PE on junior high school students under PEESHS policy and clarify the differences and correlation of overall health, physical fitness, sports participation, social adaptation, and learning facilitation. The secondary aim was to assess the practical value of PEESHS policy implementation on health promotion. Methods: The questionnaire of this study was compiled in four steps, and 31 provincial capitals across China were selected as sampling areas, using the convenience sampling method and snowball sampling method, respectively. The number of questionnaires collected was 11,373 (5703 online; 5670 offline), of which 8574 were valid, with an efficiency rate of 75.4%. Ultimately, 8574 students (4199 girls; 4375 boys) were recruited from junior high schools in 31 provinces and municipalities. Data analyses were performed using ANOVA, t-test, and Pearson bivariate correlation. Results: The results showed that the PEESHS significantly improved participants’ physical fitness, interpersonal relationships, exercise participation, learning efficiency, and psychological health after preparing for PEESHS. Exercise participation and physical fitness showed the most significant positive correlation. Excessive sports intensity was detrimental to health promotion. Conclusion: The PEESHS policy has significantly impacted the health of students participating in PEESHS.

Personality traits have close relationships with risky behaviors in various domains, including physical education, competition, and athletic training. It is yet little known about how trait personality dimensions associate with risk events and how vital factors, such as risk perception, could affect the happening of risk events in adolescent athletes. The primary purpose of this study is to investigate the prediction of risk events by regression analysis with dimensions of personality, risk perception and sports, relations between risk events, risk perception, and the facets of the personality dimensions via data collecting from 664 adolescent athletes aged 13–18 years (male 364, female 300). Secondary intent is to assess school-specific levels of training risks among sports schools, regular schools, and sports and education integrated schools. The results show that psychology events are the strongest predicted by personality traits, risk perception, and sports, followed by injury and nutrition. Emotionality has the most significant positive correlation with risk events, while other traits have a significant negative correlation with risk events, except agreeableness. The integration schools are more conducive to the healthy development of adolescent athletes’ personalities. Moreover, the research indicates that sports training can strengthen the development directions of different personality characteristics.

Background: Academic burnout represents a pressing issue among adolescents in China and has garnered increasing attention from scholars in the sport science domain. This study aims to investigate the underlying mechanisms linking physical exercise, internet addiction, self-control, and academic burnout, drawing on empirical survey data collected from adolescents in Shaanxi Province, China. Methods: This study employed a cross-sectional survey design, utilizing the Physical Activity Rating Scale (PARS-3), Chinese Internet Addiction Test (TAT), Self-Control Scale (SCS), and Academic Burnout Inventory (ABI) to collect data from 1,948 adolescents in Shaanxi Province (Mage = 13.74, SD = 1.37). Through descriptive analysis, we conducted statistical analyses on demographic variables. Utilizing Pearson correlation analysis, regression analysis, and chain mediation analysis, we constructed a relational model among variables. Results: The findings revealed significant pairwise correlations among Physical Exercise, Self-Control, Internet Addiction, and adolescent Academic Burnout. Specifically: Physical Exercise positively predicted Self-Control but negatively predicted Internet Addiction and Academic Burnout. Self-Control negatively predicted Internet Addiction and Academic Burnout. Internet Addiction positively predicted Academic Burnout. Conclusion: Self-Control and Internet Addiction independently mediated the relationship between Physical Exercise and adolescent Academic Burnout. Additionally, Self-Control and Internet Addiction jointly acted as chain mediators in this relationship.
