  Sport Participation and Happiness Among Veteran Footballers: The Mediating Role of Social Capital

  Adatepe, Eda; Kul, Murat; Özkan, Ali; Kırkbir, Fatih; Öz, Ümit; Ünlü, Yılmaz; Seleciler, Cansu; Boz, Emre

  Aim: As the global population is aging rapidly, promoting physical activity in later life is increasingly seen as a good strategy to enhance and sustain the social and psychological well-being of older adults from a positive aging perspective. This study explored how social capital influences the relationship between playing football and happiness in veteran footballers. Specifically, it aimed to understand if social capital acts as a mediator between these two factors. Materials and Methods: This cross-sectional study was performed on a convenience sample of 423 veteran footballers aged from 38 to 59 years who completed a survey at 35th Sakarya Veterans Football Tournament in Sakarya in north-west Turkey. Football participation was assessed using the Serious Leisure Inventory. Social capital was assessed in both cognitive and structural aspects. A single-item scale assessed general happiness. Data were analyzed with Pearson correlation coefficients and were calculated using SPSS (version 24) to assess the direction and strength of the links between the investigated variables. Path coefficients were calculated through regression analyses. For testing mediation effects, the study utilized Hayes’ bootstrapping method, executed with the Version 4.2 Beta of the PROCESS macro. Results: According to the research findings, the direct effect of football participation on happiness was determined to be 0.43 (p < 0.01). While community involvement played a significant mediating role with a coefficient of 0.11 (95% CI [0.05, 0.15]), the social trust and neighborhood dimensions of social capital did not yield statistically significant effects. Collectively, the model explains 24% of the variance in happiness (R2 = 0.24), with a total effect of football participation calculated at 0.57 (p = 0.000). Conclusions: it is believed that social environments that include participation in sport can contribute to successful and comfortable aging by greatly enhancing the overall well-being and happiness of older athletes/adults.

  Optimizing Budget Allocation for Digital Health Investments Using Metaheuristic Algorithms: A Cost–Impact Analysis for Public Health Systems

  Dayi, Faruk; Erdogdu, Aylin; Esmer, Yusuf; Yildiz, Ferah; Ganji, Farshad

  Background: In the era of digital transformation, public health systems increasingly rely on digital technologies to improve accessibility, efficiency, and patient outcomes. However, policymakers face significant challenges in allocating limited resources across competing digital health investments characterized by uncertainty and dynamic impacts. Methods: This study introduces the Adaptive Impact–Cost Optimization Theory (AICOT), a hybrid framework integrating fuzzy logic and genetic algorithms to optimize digital health investment portfolios. The model defines the Investment Priority Score (IPS) as a function of cost, expected impact, and implementation feasibility, enabling structured evaluation under uncertainty. A fuzzy inference system with centroid-based defuzzification is used to convert qualitative assessments into quantitative scores, while optimization techniques identify optimal portfolios across different fiscal scenarios. The empirical analysis covers 15 OECD countries (2018–2024) using publicly available datasets. Sensitivity analyses assess robustness under inflation, cost shocks, and changing system priorities. Results: The findings show that blended investment strategies combining routine digital health tools with pandemic-oriented infrastructures yield the highest resilience-adjusted efficiency. Results remain stable across sensitivity scenarios, with pandemic surveillance consistently ranking as a top priority even under increased cost conditions. The model effectively captures cross-country heterogeneity, demonstrating adaptability to different levels of digital maturity. Conclusions: AICOT provides a transparent and policy-relevant decision-support framework that improves resource allocation efficiency and reduces unnecessary expenditures. These contributions support long-term financial sustainability and align with global health objectives, including Universal Health Coverage and Sustainable Development Goal 3 (Good Health and Well-being).

  Psychological Needs and Problematic Social Media Use in Adolescents: A Gender-Moderated Mediation via Sensation Seeking and Cognitive Flexibility

  Dombak, Kübra; Yayla, İbrahim Erdoğan; Makas, Samet; Çelik, Eyüp; Sahranç, Ümit; Kaya, Mehmet

  Background: The purpose of this study is to examine the mediating roles of cognitive flexibility and sensation seeking in the relationship between basic psychological needs and problematic social media use. Furthermore, the moderating effect of gender on indirect effects has been examined. Method: The sample of the study consisted of 838 Turkish adolescents aged between 14 and 18 (46.2% female; Mean = 15.6, SD = 1.71). Participants completed the Bergen Social Media Addiction Scale, the Basic Psychological Needs Scale, the Cognitive Flexibility Scale, and the Brief Sensation Seeking Scale. Data were analyzed using structural equation modeling (SEM) with the AMOS 26.0 program. Results: A significant relationship was found between basic psychological needs and problematic social media use (r = 0.43, p < 0.001). Both cognitive flexibility and sensation seeking partially mediated this relationship in girls (β = −0.23, p < 0.001), while fully mediating it in boys (β = 0.03, p = 0.675). Conclusions: The findings suggest that problematic social media use in adolescents may be associated with cognitive flexibility and increased sensation-seeking tendencies stemming from unmet psychological needs, and that gender plays an important role in this relationship.

  Evaluation of the Association of VDR rs2228570 Polymorphism with Elite Track and Field Athletes' Competitive Performance

  Bulgay, Celal; Bayraktar, Isik; Kazan, Hasan Huseyin; Yildirim, Damla Selin; Zorba, Erdal; Akman, Onur; Ergun, Mehmet Ali; Cerit, Mesut; Ulucan, Korkut; Eken, Ozgur

  The present study aimed to examine the vitamin D receptor (VDR), rs2228570 polymorphism, and its effect on elite athletes' performance. A total of 60 elite athletes (31 sprint/power and 29 endurance) and 20 control/ physically inactive, aged 18-35, voluntarily participated in the study. The International Association of Athletics Federations (IAAF) score scale was used to determine the performance levels of the athletes' personal best (PB). Whole exome sequencing (WES) was performed by the genomic DNA isolated from the peripheral blood of the participants. Sports type, sex, and competitive performance were chosen as the parameters to compare within and between the groups by linear regression models. The results showed no statistically significant difference between the CC, TC, and TT genotypes within and between the groups (p > 0.05). Additionally, our results underlined that there were no statistically significant differences for the association of rs2228570 polymorphism with PBs within the groups of the (p > 0.05) athletes. The genetic profile in the selected gene was similar in elite endurance, sprint athletes, and in controls, suggesting that rs2228570 polymorphism does not determine competitive performance in the analyzed athlete cohort.
