This study examined the a theoretical model of direct and indirect relationships of physical perceptions latent construct including body attractiveness and physical self-worth on perceived stress of athlete employees (through mediating role of work-family conflict and its components containing work to family conflict and family to work conflict). The population included all athlete employees at Tehran Province Gas Company (TPGC) from which 187 were selected with simple random method. The applied instruments were reliable and valid. Data analysis was performed using AMOS-20 software. From the findings, it was deduced that that some modifications were needed by the proposed model and after applying these modifications, the model’s fitness parameters were optimized. According to the data of this research, it can be concluded that one of the mechanisms of the impact of exercise on perceived stress of employees is first, it improves physical perceptions and then, physical perceptions have an influence on perceived stress both directly and through increasing work-family conflict components. Theoretical explanations and future directions are outlined.
