Athlete burnout is a topic with increasing popularity in sport, as it leads to extremely impaired performance, athlete dissatisfaction and potentially even to quitting sport. Despite its relevance, there is a lack of research on this topic in Croatia. In the previous research many variables had been explored, among which the most significant ones were shown to be coachathlete relationship and athlete perfectionism. The aim of this research was to examine contribution of the variables such as coach-athlete relationship, perfectionism, self-liking and self-competence, as well as receiving salary to experiencing athlete burnout on the sample of Croatian athletes. In order to respond to the research problems, the following questionnaires were translated from English to Croatian: Athlete burnout questionnaire, Multidimensional perfectionism scale, Coach-athlete relationship questionnaire and Self-liking/self-competence scale. Male athletes have significantly higher levels of emotional and physical exhaustion in comparison to female athletes. The significant predictors of emotional and physical exhaustion are variables concern over mistakes, coach-athlete relationship and self-liking and self-competence. Significant predictors of lowered sense of accomplishment and devaluation are concern over mistakes, personal standards, coach-athlete relationship and self-liking and self-competence.
