Objective: The aims of this study were to investigate the effects and mechanisms of physical exercise input, sports emotional intelligence, and sports self-efficacy on exercise adherence, and to examine the chain-mediating role of sports emotional intelligence→sports self-efficacy. Methods: The Physical Exercise Input Scale, Exercise Adherence Scale, Sports Emotional Intelligence Scale, and Sports Self-Efficacy Scale were used to investigate 1390 college students in three universities in the Henan Province. Results: (1) Physical exercise input was a significant positive predictor of exercise adherence (β = 0.29, t = 5.78, p < 0.001); (2) sports emotional intelligence and sports self-efficacy mediated the relationship between physical exercise input and exercise adherence; (3) physical exercise input influenced exercise adherence through the separate mediating role of sports emotional intelligence (β = 0.10, t = 5.98, p < 0.001), the separate mediating role of sports self-efficacy (β = 0.13, t = 2.64, p < 0.01), and the chain mediating role of sports emotional intelligence→sports self-efficacy (β = 0.09, t = 2.80, p < 0.01). Conclusions: (1) Physical exercise input can positively predict the level of sports emotional intelligence and sports self-efficacy of college students; (2) Physical exercise input can not only directly influence college students’ exercise adherence but can also indirectly influence it through sports emotional intelligence or sports self-efficacy levels alone, as well as through the chain mediation of the two.

While the existing research has extensively explored the impact of urban green spaces on residents’ well-being, studies specifically focusing on waterfront sports buildings remain scarce. This study examines how the combined effects of built environment characteristics in waterfront sports facilities enhance user satisfaction through psychological mechanisms. Based on survey data from 721 users across nine major waterfront sports complexes in China, we find that (1) four social function dimensions (social interaction, accessibility, safety, and multifunctionality) show significant positive correlations with satisfaction; (2) place attachment mediates these relationships. These findings validate the importance of integrating water-oriented design principles with community needs, offering both theoretical contributions to human–water interaction studies and practical implications for urban blue space (defined as visible water features including rivers, lakes, and coastal areas) development.

Background: Athlete burnout is a critical psychological concern, and perfectionism—characterized by excessively high standards and self-critical tendencies—may play a role in its onset. However, prior findings on the link between self-oriented perfectionism (SOP) and burnout remain inconsistent, and the mechanisms underlying this relationship are not fully understood.Methods: This longitudinal study employed a Random-Intercept Cross-Lagged Panel Model (RI-CLPM) to examine reciprocal associations between SOP and athlete burnout, as well as the mediating role of loneliness. A total of 422 athletes (M_age = 19.74, SD = 1.77) completed three waves of assessments between June 2024 and June 2025.Results: SOP significantly predicted subsequent athlete burnout (SOP_T1 → AB_T2: β = 0.355, p < 0.001; SOP_T2 → AB_T3: β = 0.374, p < 0.001). Loneliness emerged as a significant mediator: higher SOP predicted increased loneliness (β = 0.376, p < 0.001), which in turn was associated with greater burnout (β = 0.265, p < 0.01). The indirect effect was significant (β = 0.099, 95% CI [0.033, 0.209]). Notably, no evidence supported a reverse pathway from burnout to subsequent SOP.Discussion: SOP is a longitudinal risk factor for athlete burnout, partly through its contribution to heightened loneliness. Preventive interventions that enhance social and coach support, alongside resilience-building strategies such as mindfulness, may help reduce vulnerability to burnout in athletes.

Combining the perspectives of upper echelon theory and institutional theory, we investigate how top managers’ sport experience exploits corporate environmental proactivity in China and embed this question into state ownership. With the sample of Chinese listing enterprises from 2008 to 2018, we find that both sport experience and state ownership positively promote corporate environmental proactivity, while state ownership crowds out the promotion of top managers’ sport experience. Further analyses show that position and financial experience of top manager as well as corporate investing efficiency and location matter in these processes. Thus, we extend the understanding of how top managers’ sport experience and state ownership interact and influence corporate environmental proactivity. We, therefore, provide new instruments to promote corporate environmental proactivity and, respectively, extend upper echelon theory from the perspective of top managers’ sport experience as well as institutional theory from the perspective of state ownership.

Physiological saline is an indispensable element for maintaining the functions of life. The spreading performance of physiological saline droplets on the surface of graphene under different NaCl concentrations and electric field intensities was studied in the present work. The results show that the increase in NaCl concentration reduces the displacement vector value of molecules in droplets. In addition, NaCl is easy to aggregate on the surface of graphene. The increase in NaCl concentration makes it more difficult for droplets to penetrate the surface of graphene, and the penetration angle of droplets increases with the rise in NaCl concentration. With the increase in electric field intensity, the wetting effect of droplets is more obvious. The greater the electric field intensity is, the smaller the penetration angle is, which is mainly due to the polarity of water molecules. This study has reference significance for the study of body fluid volatilization on the human surface.

Introduction: Health data equity emphasizes the need for accessible, low-cost, and scalable indicators that can reduce barriers to health assessment when applied within clearly defined populations and contexts. However, many existing fitness and health evaluation methods rely on resource-intensive measurements, limiting their applicability in large-scale or under-resourced settings. The standing long jump (SLJ), a simple field-based test of lower-limb explosive power, may serve as a practical and scalable indicator of physical fitness among male college students. Methods: This cross-sectional study included 7,842 male college students. SLJ performance was assessed alongside key health-related fitness indicators, including cardiorespiratory fitness (1000-m run), muscular endurance (pull-ups), flexibility (sit-and-reach), and body composition (BMI). Pearson correlation analysis was conducted to examine associations between SLJ and these variables. Results: SLJ performance was significantly associated with all measured variables ( p < 0.01). It was negatively correlated with 1,000-m run time and BMI, suggesting associations with better cardiorespiratory fitness performance and lower BMI within this male college student sample. Positive correlations were observed between SLJ and both pull-up performance and flexibility. These findings indicate that SLJ is associated with multiple dimensions of physical fitness in young adult men. Conclusion: As a low-cost, scalable, and easily implementable measure, SLJ has potential utility for large-scale fitness assessment among male college students. Its associations with multiple domains of physical fitness support its use as an accessible field-based assessment tool in university or resource-limited settings. Given that the present study included only male college students, the findings should not be generalized to female students, other age groups, or non-college populations without further validation. These findings contribute to the development of accessible and data-efficient strategies for context-specific health and fitness assessment.
