One of the fundamental challenges in modern societies is the prevalence of physical inactivity among various social groups, including employed women, who, owing to their specific biological and social circumstances, are among the most vulnerable populations to the consequences of a sedentary lifestyle. Accordingly, the present study aimed to identify the dimensions and components of the paradigmatic model of motivations influencing participation in sports activities, based on the subjective interpretations and perceptions of working women. This research was conducted utilizing a qualitative approach based on the grounded theory methodology. The statistical population comprised all working women in Zanjan. A sample of 13 participants was selected using a purposive sampling method. To ensure the validity of the measurement instrument, face validity was employed. Furthermore, the inter-rater reliability method was utilized to establish the reliability of the grounded theory interview analysis. The results indicated that the motivations influencing working women's participation are driven by causal conditions (enhancing physical health, promoting mental health, and achieving physical fitness). By adopting the identified strategies (offering sports discounts and subsidies, developing sports facilities, fostering a culture of encouraging sports, providing sports education and counseling, networking in women's sports, and drawing managerial attention to sports), and being influenced by contextual conditions (raising awareness about the benefits of sports, cultivating a sports culture, socializing sports, and restructuring sports development policies) as well as intervening conditions (motivation driven by family, managers, and society, alongside organizing sports competitions), these motivations can lead to several consequences. These consequences include improved efficiency; boosted self-confidence; a sense of tranquility, vitality, and happiness; feelings of enjoyment, recreation, and entertainment; strengthened physical stamina; improved physiological functions; personal and professional advancement; enhanced quality of life; reduced incidence of diseases; and healthy childbirth.
