Swimming is one of the three basic sports, it has numerous benefits for the health status and can save a life. This is precisely the reason why knowledge of this sport is important for all age categories and why it is a mandatory part of every kinesiologist's education. This research was done with the aim of determining differences in swimming performance among kinesiology students at the Faculty of Kinesiology in Osijek. The elective course Theory and Methodology of Swimming in the first year of undergraduate studies includes theoretical and practical knowledge about different swimming techniques, water sports and their application in different fields. The compulsory course Swimming and training of non-swimmers in the first year of graduate study includes learning swimming techniques, methodical procedures for training non-swimmers, and theoretical knowledge about the influence of swimming on the anthropological status and evaluation of swimming skills. The research was conducted at Osijek city swimming pool as part of the course Swimming and training of non-swimmers, on a sample of 44 first-year graduate students, 16 of whom participated in an elective course during undergraduate studies. Students were tested in 12 variables, i.e. 4 each for crawl, backstroke and breaststroke techniques. The results indicate that there is no statistically significant difference in swimming performance in all variables between students who participated in the original course and those who did not.
