Body movement is one of the basic needs of every being, especially one that is developing. Children in their first years of life adopt habits and behaviors that they will use throughout their lives, so it is advisable to include children in any form of physical movement and exercise as soon as possible. A physical education lesson and physical play are the best examples of encouraging children to move in kindergarten. However, except these forms of exercise, playing sports from an early age can have an even more positive effect on a child’s development and health. This primarily talks about motor knowledge and abilities that can only be developed through exercise, and also include natural forms of movement. If this is ignored in children, stagnation occurs, but also a decrease in the development of these abilities. Each of these abilities can be measured by various tests where the current motor status of children is assessed based on the results and the training process is adjusted according to the results. In addition, the training process includes a global, operational and performance plan, as well as the daily preparation of educators for training with children. The aim of this study was to compare two groups of children, those who play sports and those who do not attend any of the additional forms of kinesiological activities. Specifically, the tests aimed to compare the development of their motor skills. The results showed that in five of the eight tests conducted, children who play sports are better. Descriptive analysis concluded that non-sports children are better at repetitive strength (abs) tests, coordination (polygon backwards) and flexibility (hull ancestor).Furthermore, statistical analysis can conclude that in the explosive leg strength test, children athletes bounce the most in results, that is, in this test they achieved significantly better results than the group of children who do not play sports.
