In today's modern times, sport has become one of the most important social phenomena. It has integrated itself into every pore of society, from the media, economy, health and tourism. Sport is no longer just a competitive game where the only thing that matters is who wins or loses. It has become a business unto itself, a sector unto itself. Ever since sports began to be quoted in multi-million dollar amounts and since athletes became some of the richest people in the world, it has become obvious that sports have reached a whole new level. Today, the sport is so popularized that in one hand it has even lost part of its meaning. He lost his part of the game but gained the characteristic of business. Although sport is extremely developed today and new top athletes with new and stronger talents are being created every day, there are still big problems that mostly relate to the financing system. Accordingly, this research work refers to the collection of data concerning the financing of top athletes in the Republic of Croatia. In this research work, qualitative methodology was used, that is, through semi-structured interviews, data related to the social and economic aspects of top athletes in the Republic of Croatia were obtained. The data was obtained from six participants (top athletes) who gave us an insight into their life, habits and work tasks and they gave their opinion on the economic state of sports in Croatia, on the problems they face every day and on the lack of care of institutions for athletes. This research will show all the problems that athletes face every day while training the sport they love in Croatia; the actual state of the sport will be shown and the development of the sport from history until today will be shown. The above will be supported by relevant theories and works of large number of sociologists, economists and kinesiologists.
