The aim of this graduate thesis is to determine the impact of swimming programs on the ability of children with disabilities to swim. In accordance with the aim of the thesis, a survey was conducted in the Natator swimming club to determine the shift in swimming over a period of 5 months. Children with disabilities face many challenges, one of which is involvement in physical activities. Physical activity has multiple positive effects on a child's overall development - physical, cognitive, emotional and social. Swimming and water activities are considered to be one of the most comprehensive forms of exercise, as they have a very beneficial effect on all parts of the body, organs and physiological functions. Swimming has a positive effect on the cardiovascular, muscular, respiratory and thermoregulatory systems. Swimming programs for children with disabilities must take into account their specifics in terms of their abilities and motivation. An important role in motivating, planning and conducting swimming training is played by coaches who must adapt the load and activities to the capabilities of each swimmer. The aim of the research conducted for the purpose of writing this thesis is to try to determine the effects between the swimming program and the ability to swim in the 25 meters freestyle, or determines that there is a difference in swimming opportunities after five months of inclusion in the program. The study included 26 subjects (9 girls and 17 boys) and included an initial measuring in October 2019 and a final measuring in February 2020. The results obtained by t-test analysis show that there is no statistically significant difference between the time the subjects swam 25 m freestyle in the initial measuring and the final measuring. Although there is no statistically significant difference, according to descriptive data, it is evident that the respondents swam 25 meters faster in the final measuring. Thus, it can be concluded that the swimming program in which children with disabilities were involved, affected the ability to swim, which is reflected in the better results obtained in the final measuring.
