This study examines the impact of visual occlusion training on motor performance and visual prediction in judokas. By limiting parts of the visual field, these exercises prompt athletes to focus more on remaining visual cues, enhancing predictive abilities. The research aims to evaluate the effectiveness of central and peripheral occlusion in judokas. The study employed an experimental design with a pre-post test and control group, involving 45 judokas aged 15-45. Results showed significant improvements in motor performance and visual prediction in both occlusion groups post-intervention. These findings suggest that visual occlusion training can be an effective tool for enhancing motor and predictive skills in athletes, contributing to the development of novel training programs. These results can assist coaches and athletes in improving performance.  

Purpose: The aim of this research is to compare the effects of three training methods — plyometric, weighted, and barbell (Turkish) training — on the anaerobic capacity of high school male volleyball players. A total of 48 subjects, aged 23 ± 5 years, were selected purposefully and randomly divided into four groups of 12 participants each. Method: The height and weight of the participants were recorded, and their anaerobic capacity was measured using the Lewis formula based on the vertical jump test during the pre-test. The three experimental groups performed weight training, plyometric exercises, and plyometric exercises combined with weights, respectively. The fourth group followed a standard volleyball training regimen. The training period lasted eight weeks, with three training sessions per week. After the eight weeks, a post-test was conducted to measure the effects of the different training methods on the participants' anaerobic capacity. Results: The results of this study showed: Eight weeks of weight training significantly improved the anaerobic capacity of the volleyball players eight weeks of plyometric training significantly improved the anaerobic capacity of the volleyball players. Eight weeks of barbell (Turkish) training significantly improved the anaerobic capacity of the volleyball players.There was no significant difference between the effects of the three training methods on anaerobic capacity. Conclusion: Based on the results of this research, it can be concluded that weight training, plyometric training, and barbell training are all effective in increasing the anaerobic capacity of volleyball players. Given the available time, number of athletes, and resources, any of these training methods can be selected to improve the anaerobic power of athletes. Coaches may choose the most appropriate method depending on the specific needs of their athletes and the resources available.

Over the past decade, research on artificial intelligence (AI) has expanded significantly, exploring its potential to enhance the quality of life for older adults. Therefore, the study aims to investigate the effect of a 4-week AI-generated Pilates training program on motor performance and fear of falling in older adults. This quasi-experimental study selected 30 female older adults aged 65 years and older, dividing them into two groups: one for experimental (N = 15) and another for control (N = 15).  The experimental groups had four weeks of AI-based intervention with three sessions per week. During this period, the control group engaged in the routine activities. The Timed Up and Go and the Falls Efficacy Scale-International (FES-I) questionnaire were done as pre-posttest, respectively. The independent t-test was used for inferential statistics. Data analysis was conducted at a significance level of 95% with an alpha level less than or equal to 0.05. The findings showed that there was a significant difference between the two groups in the scores of the TUG test (p<0.03) and the FES-I questionnaire (p<0.001). By utilizing AI to develop personalized exercise programs, healthcare practitioners can improve motor performance and reduce the fear of falling in older adults. These findings highlight the potential of AI-driven rehabilitation strategies in geriatric care, emphasizing the need for further research to refine program parameters and extend their benefits to a broader aging population.  

Athletes with disabilities navigate a landscape of unique challenges: limited infrastructure, scarce resources, financial uncertainty, and pervasive social barriers, all alongside the physical and mental demands of elite sport. These pressures can heighten vulnerability to burnout, anxiety, depression, and other psychological risks. Yet, narratives reveal remarkable resilience, determination, and adaptive coping strategies that emerge through lived experience. This paper highlights the critical role of managers, coaches, and technical staff in shaping environments that sustain mental health and performance. By leveraging emotional intelligence, participatory decision-making, ethical reasoning, and cognitive management during crises, leaders can foster cohesion, motivation, and psychological safety. We advocate embedding structured psychological-care protocols within managerial practices, supported by interdisciplinary collaboration with sport psychologists. Synthesizing empirical findings and first-hand accounts, this study presents actionable strategies for optimizing both competitive success and quality of life, emphasizing that holistic, informed management is pivotal to empowering elite athletes with disabilities while safeguarding their well-being.

This study investigates the impact of brand symbolism on brand evangelism behavior among Persepolis Club evangelists in Mashhad during spring 2024. As an applied descriptive-correlational research, data were collected from 320 purposively sampled participants using standard questionnaires: Osmanova et al. (2023) for brand symbolism and Becerra and Badrinarayanan (2013) for brand evangelism. The reliability and validity of the instruments were confirmed through Cronbach’s alpha, internal consistency, composite reliability, and convergent and discriminant validity tests. Structural equation modeling (SEM) via LISREL was employed for data analysis. Results show that brand symbolism significantly affects brand evangelism and its components, including purchase intention (path coefficient = 0.45), positive word-of-mouth (0.30), and negative word-of-mouth against competitors (0.12). Purchase intention further influences positive (0.51) and negative word-of-mouth (0.45), while positive word-of-mouth also impacts negative word-of-mouth toward rival teams (0.27). These findings suggest that brand symbolism positively drives evangelism behaviors such as purchasing Persepolis products and promoting the club while discouraging competitor support. Based on these outcomes, it is recommended that Persepolis Club enhance its brand symbolism through targeted marketing strategies—such as exclusive fan events, social media engagement, and branded merchandise—to deepen fans’ emotional connection and strengthen brand evangelism. Such initiatives are likely to boost positive purchase intentions and supportive word-of-mouth, benefiting the club’s overall brand strength.
