We investigated the relationship between self-efficacy and career development via subjective well-being of students majoring in physical education. Life satisfaction, positive affect, and negative affect were the componennts of subjective well-being. Participants were the 1381 adolescents with major in physical education with an age range of 18–22 years (Mage = 19.5 ± 1; females = 34.76%). Hayes PROCESS model was used to develop a multiple mediation model. The results suggest that higher self-efficacy leads to better career development. Further, a significant mediating role was played by negative and positive affect in case of the relationship between self-efficacy and career exploration, but life-satisfaction is not significant mediator. Conversely, life satisfaction and positive affect are significant mediators between self-efficacy and career adaptability but negative affect is not. The findings suggest that self-efficacy and subjective well-being benefit career development of adolescents in the physical education field.

Public sports venues serve as a crucial material medium for human athletic activities. Research on their spatial distribution holds profound implications for optimizing spatial layout and promoting human sports endeavors. This paper takes interest points of sports venues in China as research samples, employing GIS spatial analysis tools, mathematical statistics, and Geo-detector as research methods. It systematically investigates the spatial distribution characteristics and causes of sports venues in China, aiming to provide insights and references for the optimization of spatial arrangement, sustainable development, and relevant policy formulation of sports venues in the country. The results indicate that: (1) In terms of overall distribution characteristics, sports venues in China present a multi-centric agglomeration in geographical space. (2) From a regional distribution perspective, the spatial layout of these venues reveals a pattern of “more in the south, less in the north,” “dense in the southeast, sparse in the northwest,” and a coastal strip distribution. (3) Regarding spatial correlation, the hot and cold spot partitions of sports venues largely align with the “Hu-Line”, with their spatial distribution tending towards a positively correlated pattern of high–high clustering and low–low clustering. (4) There is evident heterogeneity in factors affecting sports venues’ spatial distribution. The distribution results from the interactive coupling of multiple factors, where the interaction between any two factors offers stronger explanatory power for the spatial layout of the venues.

In China, the physical activity of adolescents is declining nowadays, which may be linked to their health locus of control, social support, and self-efficacy. The current study has investigated the role of health locus of control, social support, and self-efficacy in adolescents’ physical activity. Using convenient sampling, 569 (18–21 years old) adolescents were surveyed. There were 313 (55.01%) females and 256 (44.99%) males. Data were collected through questionnaires on the study variables. The results display that physical activity is directly positively affected by locus of control, self-efficacy, and social support. Both self-efficacy and social support are positively associated with locus of control and physical activity. Further, locus of control also indirectly affects physical activity through self-efficacy and social support. To conclude, we can say that locus of control, self-efficacy, and social support play a significant role in promoting physical activity. The study suggests developing effective future interventions by considering the study variables to increase physical activity.
