In order to point out the negativity of a sedentary lifestyle, nowadays, positive aspects of exercise are highlighted (Garilović, 2017). However, in addition to the positive, there are also some negative effects of exercise. Moreover, in case a person overuses exercise, it can develop an addiction (Hausenblas and Symons Downs, 2002b). Researchers (Hausenblas and Symons Downs, 2002a; Miller and Mesagno, 2014) have pointed out the need to create a personality profile of individuals who are addicted to exercise. In addition, there is a specific type of personality called narcissistic perfectionism which is characterized by a combination of narcissistic and perfectionistic traits and precisely perfectionism and narcissism have been shown to be important factors for the development of exercise addiction (Miller and Mesagno, 2014). Therefore, the purpose of the present study was to explore the relationship between perfectionism, narcissism and exercise dependence. Two hundred and one student participated in the research of which 125 were women and 76 were men. Participants completed the Exercise Dependence Scale-21 (EDS-21; Hausenblaus and Symons, 2002b), the Multidimensional Perfectionism Scale - Frost (MPS-F; Frost, Marten, Lahart and Rosenblate, 1990), Pathological Narcissism Inventory (PNI; Pincus et al., 2009) and Demographic Data Questionnaire. It has been shown that there is no significant difference in exercise addiction with regard to gender. Also, dimensions of perfectionism and pathological narcissism explained 12 % of variance in exercise addiction. However, only personal standards dimension was significant predictor of exercise addiction in the way that individuals who set higher personal standards were at risk for developing exercise addiction.
