ObjectiveTo explore the role of college students' core self-evaluation in the association between extracurricular physical exercise and academic stress, and to provide a reference and basis for effectively alleviating current college students' academic stress.MethodsA stratified cluster random sampling method was used to conduct an online survey using the China College Student Mental Health Screening Scale, the Core Self-Esteem Scale, and a self-developed questionnaire for 1,249 college students from 8 junior colleges in Jiangsu Province, China, in January 2023, and analyses were conducted using bivariate correlation and mediation effect tests.ResultsMore than half of the students were worried about lagging behind other students in their studies and worrying about exams, as well as more than half of the students had <2 h of extracurricular physical exercise per week in terms of academic stress. Significant correlations were found between extracurricular physical exercise time and core self-evaluation (r = 0.225, p < 0.01), academic stress (r = −0.317, p < 0.01), and between core self-evaluation and academic stress (r =−0.371, p < 0.01). Extracurricular physical exercise had a negative predictive effect on academic stress (effect = −0.306, 95%CI: −0.361~-0.251) and partially through the mediating path of core self-evaluation, (effect = −0.067, 95%CI: −0.091~-0.046), with a mediating effect of 21.9%. Among them, the mediating effect of core self-evaluation was highest in “worrying about lagging behind other students in their studies” and “worrying about exams”, which accounted for 24.4% and 24.3% respectively.ConclusionCurrently, college students have different degrees of academic stress; extracurricular physical exercise can reduce academic stress through direct effects, and also through the indirect effect of improving the level of core self-evaluation, and active extracurricular physical exercise has become an important way to promote students' physical and mental health.

Objective With the prevalence of electronic media use among Chinese adolescents and concerns regarding its potential negative consequences on their health and development, this study investigated the relationship between physical exercise and electronic media use. Utilizing data from the China Education Panel Survey, we examine the impact of physical activity on adolescents’ electronic media use. Methods A simultaneous equation model, including two-stage least square and three-stage least square, was employed to estimate the impact of physical activity on electronic media use among adolescents. Self-control theory and media addiction theory were also used to analyze electronic media use in adolescents. Descriptive statistics were used to analyzed the data. Results Chinese adolescents dedicated a substantial amount of time, averaging 2.95 hours per day, to electronic media activities. Increasing physical activity demonstrated an effective means to reduce electronic media use. Furthermore, the impact of physical activity on electronic media use exhibited urban-rural stratification, with family factors related to social class status primarily influencing electronic media use among urban students, while physical activity has a more pronounced influence among rural students. Conclusions Promoting physical activity represents a compelling and effective strategy for curbing excessive electronic media use among Chinese adolescents, particularly in rural areas where physical activity has a stronger influence. In addition, controlling media entertainment and recreation time and enhancing social cohesion can help to weaken media interest. While changing the social class status of families in urban areas may be difficult in the short term, parents should be aware that physical exercise is an effective way to reduce their children’s use of electronic media. Our findings suggested that promoting physical activity may be a promising strategy for reducing excessive electronic media use among Chinese adolescents, particularly in rural areas where physical activity has a stronger influence.

Improving the employment quality of retired athletes is crucial to enhancing the well-being of individual athletes and promoting the high-quality development of competitive sports. Based on micro-survey data, OLS and quantile regression were used to analyze retired athletes’ human capital influence on their employment quality. The empirical results show that: the employment quality of retired athletes in J province varies greatly among individuals, and the overall employment quality is not optimistic; human capital has a significant positive influence on the employment quality of retired athletes, with the degree of influence in descending order of athletic rank, vocational skill training, the degree of marketability of the sport engaged in, and health capital; the effect of each element of human capital on different levels of employment quality has a distribution heterogeneity. Based on the results of the study, suggestions are made to take into account equal opportunities for athletes of different sports to attend school, enhance the cultural and educational capital of athletes, improve the multi-level medical security system, strengthen vocational skill training and innovation and entrepreneurship training, and build a collaborative employment governance model to improve the employment quality of retired athletes.
