Isomorphism is the process by which organizations become more similar to each other over time. The purpose of this study was to explore how previous research has examined this phenomenon in sports organizations. We used a semi-systematic approach to conduct the research. In conducting and reporting the review we followed the four stages that are outlined by Snyder (2019). A total of 126 articles underwent an abstract review process, from which 26 articles were extracted. Finally, 13 qualitative articles that related to the research objectives were reviewed. We conducted a content analysis of 13 articles on isomorphism in sport. The articles were published in a variety of academic journals between 1990 and 2023. 8 main themes are presented: Type of isomorphism, Mechanism of isomorphism, Consequences of Isomorphism in Sport Organizations, Function of Isomorphism, Strategies for response to pressure, institutional logics, Application of Isomorphism in Sports Organizations, Managing Isomorphism in Sport Organizations. Results showed isomorphism in sport organizations is driven by three primary mechanisms: coercive isomorphism, mimetic isomorphism, and normative isomorphism. In conclusion, isomorphism is a complex phenomenon that can have both positive and negative consequences for sport organizations. By understanding the mechanisms of isomorphism and carefully managing its effects, sport organizations can leverage its benefits while maintaining their strategic autonomy and fostering a culture of innovation and adaptation.
