This research aims to integrate practical and theoretical solutions to increase motivation for sports participation among workers. The study employed a cross-sectional and correlational design, focusing on the statistical population of employees at Iranol Oil Company in Tehran in 2019, which consisted of 890 individuals. Based on Karjesi and Morgan's table, 261 participants were selected using an available sampling method. The research utilized tools for measuring motivation for sports participation (Gill et al., 1984), cognitive regulation of emotion (Garnefsky and Kraij, 2006), and feelings of joy (Argill and Lowe, 1990). Structural equation analysis was employed to test the research hypotheses. The findings indicated that the model had a good fit. Specifically, in the final model, the standard path coefficients for adaptive and maladaptive cognitive emotion regulation on sports participation motivation were 0.17 and -0.40, respectively. This suggests that the skill of cognitive emotion regulation (a practical strategy) plays a significant role in the relationship between feelings of vitality (a theoretical approach) and motivation for sports participation. The developed model for sports participation motivation serves as a foundational tool for creating practical programs aimed at enhancing participation in sports among various groups. Additionally, implementing interventions to teach individuals emotion regulation strategies—along with fostering changes in cognition and behavior—can promote self-regulation and subsequently increase sports participation. Finally, efforts to enhance societal vitality represent a theoretical solution to reduce maladaptive emotional regulation, thereby fostering greater motivation for sports participation.

Background: Work-related musculoskeletal disorders (WMSDs) impose a heavy burden on individuals, organizations, and governments.Aim: The purpose of this study was to provide information about WMSDs and working posture. This information can be helpful in designing preventive programs.Materials and Methods: The present study is a descriptive-analytical study. 207 subjects participated in this study. For WMSDs investigation and postural assessment during work, Nordic Questionnaire and Rapid Upper Limb Assessment (RULA) method were used, respectively. Gathered data from research variables measurement analyzed using Chi-square test and descriptive statistics. A p value of equal or less than 0.05 took into account to be statistically significant.Results: The most prevalent work–related musculoskeletal disorder was found in lower back region, the percentage for large, medium and small ships staff was 58%, 61.7% and 45.1%, respectively. A significant relationship was found between WMSDs in neck (P=0.001), hands and wrists (P=0.02), back (P=0.04) and knees (P=0.001) and used ship by staff. A higher proportion of level four corrective action, was found in small ship staff.Conclusion: WMSDs are prevalent among staff of all ships. WMSDs are more prevalent in lower back. Also, immediate change in posture and investigation is more necessary in small ship staff.
