Autism is a disease that is increasingly affecting children nowadays. With all the symptoms associated with autism, reduced motor skills is one of them. This affects the daily lives of children with autism spectrum disorders. The main goal of this study was to check the impact of exercise on one specific polygon on the ability to solve the same tasks (the same polygon) as well as the ability to solve other motor tasks (solving another polygon). The study was conducted on 10 children with autism spectrum disorders who are participants of the Tennis Club "Travnjak", with an average age of 10.50 ± 2.59 years, an average height of 152.80 ± 16.33 cm and body weight 47.60 ± 20.02. The subjects conducted initial, transit and final testing over a period of 27 weeks, and in the periods between them, they conducted training programs 2 times a week. The tests measured the time required to pass through polygon A and polygon B, the number of repetitions in the test under the fuselage from lying down, the distance of the long jump, the distance of reach in the test preclude in the multiple position and the number of repetitions in the step test. The results show a statistically significant decrease in time when passing through the same, i.e. the second polygon. Improvement in motor skills has also been noted. In the step test, the torso from the supine position and the test of the torso in a varied position, a statistically significant improvement was recorded, while in the test, a positive trend was recorded. Given the results obtained, the proposed training could be used as an independent fitness program or as part of the daily physical activity of children with autism spectrum disorder. In future research, a larger number of children should be included, i.e. expanding the base with more clubs.
