However, the strength and nature of these effects vary. The \"managerial presidential\" and \"couple's presidential\" models show relatively stronger associations with performance outcomes, particularly in federations with established professional staff structures. These differences suggest that while each model contributes, their practical effectiveness depends on how clearly responsibilities are distributed and how decision-making is shared among key actors. This paper contributes critical insights into the relationship between governance models and organizational performance in the context of nonprofit sports organizations. The findings suggest that the implementation of an appropriate governance model can lead to significant improvements in both sports results and financial resources.

A career in elite sports means that elite athletes must take extreme health risks and at the same time protect their health to continuously deliver peak performances. According to Fletcher and Hanton, psychological research is confronted with a particular challenge because elite athletes are subject to numerous stressors both during and after their sports career. The examination of the relevant stress-related factors (relationships, competitive pressure, defeat, injuries, etc.) points to a growing body of evidence signifying that these factors could be responsible for mental health problems in the target population.
