The objective of this study is to check whether the type of sport is important for the development of the dual career in professional sport. This study utilised the Chi-square test of the independence measurement model and student’s T test. It also analysed 7 scenarios. A final survey-list consisted of the 38 items of competences and it was completed by 243 young people who took part in this study; the sample included 151 (67.7%) athletes training individual disciplines and 72 (32.3%) team disciplines. The statistically significant results between the groups are in terms of competence (scenarios 3 and 6). There were no statistically significant differences between the groups in terms of life experience. Results in both parts of the study confirmed the three hypotheses. It turned out that the type of sport does not affect the course of the dual career in professional athletes.
