This research was carried out with the aim to determine the differences in dimensions of pre-competition anxiety in players of different age. Respondents of the study were 14 handball players of the “Balić Metličić” Club Split, who played for senior and U-16 age category. Before the matches, they were given a questionnaire to measure the level of anxiety. The questionnaire measured three dimensions: self-confidence, cognitive anxiety and somatic anxiety. Hypothesis according to which the older players should be more confident and less anxious were set and proved to be right, according to the results. The assumption was, that during their sports career, the older players, besides their physical form, had also developed psychological stability. It is obvious that the seniors have more confidence in themselves and their abilities and believe that they can better perform specific tasks that would lead them to the positive result of the game. The reason for this might be a better technical performance gained by the high number of repetitions and years of training. Longer training and playing experience lead to a decrease in the number of faults in the performance of technical elements such as shooting, assists, scores etc, giving older players a certain level of security over cadets/U-16.
