The research had been conducted on the sample consisting of 88 girls and boys attending the 3rd grade of Elementary School. The aim of the research was to establish the effects of training of the basic elements of swimming created under the impact of programmed work within the frame of extra-curriculum acitivities. For the purpose of analysing the differencies between initial and final testing, was used T-test for dependent samples as well as percentage analyses. On the basis of final parameters, statistically significant positive changes had been noticed with the all variables as a result of applied training programme. By correct paedagogical approach, the majority of children have shown positive changes in regard of learning of the basic elements needed for the movement in the water. From the theoretical and practical point of view it could be stated as this programme is highly useful and applicable as a form of extra-curriculum activity.
