In order to improve the performance of the activities, organizations continually move towards improvement of their management and structure. In this movement, professionalization rises as a consensus requirement to the survival and development of the organizations, including the sports organizations. This work`s theme is the professionalization of Brazilian sports organization`s management and has the main goal of identifying aspects of the organizational field that affect the process of professionalization of sports organizations. The Brazilian Volleyball was used as a case study, sport that is considered the best organized in the country. Concepts of the Institutional Theory have been considered in order to comprehend the Brazilian Volleyball organizational field`s dynamic and how it influences the process of professionalization, justifying the strategic move of the sports organizations. The research involved interviews with representatives of the Brazilian Volleyball organizational field`s groups of actors, such as players, teams, sponsors, federations, Government, within others. The results show that the professionalization rises within values, ideas and social rules shared by the actors of the field, and is considered important to improve the performance of sports organizations. Although it is a shared value, it has been noticed that there are divergences on the way the sports organization should adopt the professionalization of its management.
