Objectives: The objective of this study is to formulate a model for national champions' reluctance to sport retirement. Methodology: This research is exploratory-fundamental in terms of scope, qualitative in terms of methodology, and data-based in terms of strategy, with theoretical foundations and interviews as its data collection source. The population includes coaches, physical education masters, retired athletes and athletes. Targeted and quota sampling was conducted for exploratory interviews and the interviews with 22 people accounted for theoretical saturation. The interviews were depicted in Maxqda software for qualitative data analysis, along with open coding, axial coding and selective coding of reluctance to sport retirement, and the theory was created. Results: According to the results, 261 open codes with 21 main categories and 49 sub-categories were extracted in form of a paradigm model of factors of champions' reluctance to sport retirement including economic, individual, sport, social, management and political conditions. Conclusion: Managers, coaches and athletes' approach toward sport retirement can facilitate the development of programs to adapt individually and organizationally to sport retirement away from individual, social, economic, management and political crises. The research theory was presented along with categories on causative conditions, background factors, interventional factors, strategies and outcomes.
