The main purpose of this investigation was to examine the relations of practiced sports and sports betting. The first aim of the study was to determine the link between the following indicators: gender, age, education, practiced sports and the intention to bet. Thus, the study starts from the hypothesis that males are more prone to bet. It is also assumed that people who practice sports betting tend to practice casino gambling too. The study was conducted on a survey group of 82 respondents (N=82), aged between 20 and 30 years. From this group of respondents, 47 were athletes and the rest were non-athletes. The Proactive Attitude [1] and the Personal Growth Initiative Scale (PGIS) scales have been applied [2], but the results of the research did not confirm the hypothesis that bettors will get lower scores on both scales, the differences being insignificant. It has been demonstrated that men have an increased tendency to bet towards women. It has also been shown that bettors are more inclined to practice casino gambling. The practice of sports correlates positively with the tendency to bet and it has been shown that those who practice team sports are more prone to bet than those who practice individual sports.
