This paper deals with the development of a financial management maturity model for sports organizations based on artificial intelligence. We jointly consider enhancing financial transparency, oversight and control, risk management, and using advanced technologies in sports organizations. The proposed scheme relies on a constructivist grounded theory approach. The research process involved data collection through in-depth interviews with five AI language models, ChatGPT, Claude, Google Gemini, Mistral, and LLaMA. In addition, these models were utilized as an alternative to traditional experts. Finally, extensive simulations were conducted to validate that 209 initial codes were identified, which were then refined to 44 codes and eventually consolidated into 11 key themes. These themes include financial transparency, oversight and control, budget planning, risk management, and the use of advanced technologies. Numerical results show the efficiency that these themes are interlinked in a chain-like manner and contribute to enhancing the financial efficiency of sports organizations.

Purpose: With the aging population facing an increased risk of ocular conditions such as glaucoma, age-related macular degeneration (AMD), and diabetic retinopathy, finding non-invasive methods to support eye health is essential. This meta-analysis aims to compare the effects of aerobic, isometric, and resistance exercises on visual acuity and overall eye health in the elderly, seeking to identify which type of exercise may be most beneficial for maintaining or improving eye health. Method: A systematic review and meta-analysis were conducted following standard guidelines. Electronic databases, including PubMed, Scopus, and Web of Science, were searched for relevant studies published between 2000 and 2023. The search included terms related to aerobic, isometric, and resistance exercises, visual acuity, intraocular pressure (IOP), retinal health, and elderly populations. Studies were screened and selected based on predefined inclusion criteria, focusing on research involving elderly participants and outcomes related to eye health. Results: A total of 15 studies met the inclusion criteria, encompassing 1,200 participants with a mean age of 68 years. The meta-analysis revealed that aerobic exercise significantly reduced intraocular pressure (mean difference = -2.5 mmHg, 95% CI: -3.2 to -1.8, p < 0.001) and improved retinal health markers (effect size = 0.35, 95% CI: 0.20 to 0.50, p < 0.01). Resistance exercise was associated with enhanced visual acuity (effect size = 0.28, 95% CI: 0.15 to 0.41, p < 0.01) and a reduction in the progression of AMD (relative risk = 0.70, 95% CI: 0.50 to 0.90, p < 0.05). Isometric exercises showed minimal impact on eye health compared to the other exercise types (effect size = 0.05, 95% CI: -0.10 to 0.20, p = 0.40). Conclusion: This meta-analysis supports the idea that aerobic and resistance exercises can protect visual acuity and overall eye health in the elderly, likely due to improved blood circulation, reduced oxidative stress, and enhanced retinal function. In contrast, isometric exercises showed minimal benefits, potentially due to their limited impact on systemic circulation. These findings suggest the importance of specific physical activities for mitigating age-related ocular disease risks, with implications for clinical and public health guidelines aimed at preventing visual decline in aging populations.

Purpose: Today, sport is considered as an industry and sports as a science discipline recognized in the world, requires effective cooperation with industry. The development of sports is accompanied by the development of science, which doubles the need for appropriateness and attention to the field of science to develop entrepreneurship in the university and the relationship with industry. In this regard, the purpose of this study was to design an entrepreneurial curriculum model with an emphasis on the relationship between industry and academia in the sports science . Method: The research approach was qualitative and used a grounded theory methodology and in-depth interviews were used for this purpose. Participants included students and professors of sports sciences at public universities, who were considered as 23 according to the purposeful sampling . Results: The results showed that the university structure, communication with industrial institutions and centers, training of university manpower are effective in developing the entrepreneurial curriculum model and the development of learning in the real world. As a result, to strengthen the curriculum, the need to pay attention to cooperation between institutions and gain experience through internships and contracts between universities and the participation of other disciplines as well as industrial centers can strengthen knowledge, skills, and attitudes . Conclusions: It seems that the increasing practicality of educational programs and their close relationship with the sports industry and related organizations can affect sports entrepreneurship in society .
