Organizations, nowadays, operate in highly dynamically-developing environments. This fact also applies to sports organizations, which are looking for various ways to succeed or survive in these environments. There are various solutions available, but from a long-term perspective it is important for sports organizations to think in a complex way. One of the solutions of this issue is to ensure the long-term sustainability and development of these organizations. The aim of this paper is to focus on strategic factors in the management of mutual relationships with stakeholders. The importance of managing cooperation with stakeholders is very high for the achievement of both short-term and long-term objectives. This paper presents, in addition to the results of research aimed at the cooperation of sports organizations and their stakeholders (425 respondents participated in the research), solutions to issues currently troubling sports organizations in this field. These issues include the lack of funds for the functioning of the sports organization, as well as the insufficient size of sports organization membership. Sports organizations cannot only reduce the intensity of these issues, but can also eliminate them by utilising selected key factors in the management of mutual relationships with stakeholders.
