This research was conducted with the aim of integrating practical and theoretical strategies to enhance the motivation for sports participation among workers. The design of this research was cross-sectional and correlational. The statistical population of the present study consisted of all employees of Iranol Oil Company in Tehran in 2020, totaling 890 individuals. Among them, 261 were selected based on the Krejcie and Morgan table using the available sampling method. In this study, the tools used were the Sports Participation Motivation Scale (Gill et al., 1984), the Cognitive Emotion Regulation Questionnaire (Garnefski and Kraaij, 2006), and the Subjective Vitality Scale (Ryan and Frederick, 1997). Additionally, structural equation modeling was used to test the research hypotheses. The research findings indicated that the model had a good fit. Accordingly, the findings showed that in the final model, the standardized path coefficients for adaptive and maladaptive emotion regulation on sports participation motivation were 0.17 and -0.40, respectively. Therefore, the skill of emotion regulation (practical strategy) was significant in the relationship between the feeling of vitality (theoretical strategy) and sports participation motivation. Using the results obtained from the developed model of sports participation motivation, a foundation is laid for creating practical programs to improve the inclination towards sports participation among various segments of the population. Additionally, implementing interventions to educate individuals on learning emotion regulation strategies through changes in cognition and behavior to achieve greater self-regulation provides a practical basis for increasing sports participation. Ultimately, focusing on enhancing community vitality serves as a theoretical approach to reducing maladaptive emotion regulation, thereby fostering the growth of sports participation motivation.

Visual impairment significantly impacts physical activity participation, often leading to reduced fitness levels among affected individuals. This study aims to compare the physical fitness characteristics of male and female goalball athletes aged 14-20 years, a critical developmental period for performance enhancement. A total of 100 athletes (50 male, 50 female) were assessed for strength, endurance, power, flexibility, and balance through various standardized tests. Results indicated significant differences in hand grip strength, medicine ball throw distance, vertical jump, and balance, with males outperforming females (p < 0.05). No significant differences were found in push-up and sit-up performance, suggesting comparable endurance capabilities across genders. These findings underscore the necessity for gender-specific training regimens to address identified disparities, particularly in strength and power. The study contributes to a limited body of literature on the physical fitness of goalball players and highlights implications for inclusive training strategies that enhance athletic performance regardless of gender. Future research should explore the correlation between physical fitness attributes and on-court performance metrics to further inform coaching practices.

Visually impaired individuals have higher risk of injuries particularly in sports like goalball. It is specifically designed for the visually impaired people. It is imperative to prevent injuries prior to their occurrence for avoiding negative effects on sporting success, financial losses, and motivation. This study was aimed to determin the Epidemiology and Associated Factors of Sports Injuries in Iranian Goalball Athletes. This study is a descriptive-correlational and retrospective research. A total of 205 male and female goalball athletes, aged between 18 and 50 years, completed the injury registration form. The Fuller et al. injury registration form was utilized for data collection. The information gathered included injury prevalence, injury mechanisms, injury severity, injury incidence across different anatomical regions, injury timing (training/competition), and injury type (acute or chronic). Frequency and percentage were used to assess injury prevalence, and the Chi-square test was employed to analyze relationships between variables. The highest prevalence of injuries was related to contusions and bruises (28.3%), while fractures and dislocations had the lowest prevalence (3.9%). No significant relationship was found between sports injury prevalence and factors such as age group, activity history, activity level, and sports class. The knee exhibited the highest frequency of local and overall anatomical injuries (19.5%), while the sole of the foot had the lowest frequency (1.0%). The most common types of injuries were facial and cheek abrasions, cuts, and wounds (8.3%), followed by wrist and shoulder muscle strains, each affecting 15 athletes (7.3%). Regarding injury mechanisms, the most fre
