Involving children in sports at an early age contributes to their physical and mental health. The motor skills that a child develops during childhood greatly influence his abilities later in life. Although it is known that physical activity is one of the most important factors for the healthy development of children, some studies show that more and more children are insufficiently active, which results in obesity and numerous other health losses. It is extremely important to educate parents and educators about the importance of sports, how it contributes to a better quality of life, and what benefits children achieve by engaging in physical activity or sports. Therefore, the goal of this research was to determine the current state of motor skills of preschool children and whether there is a difference in the motor skills of children who play sports and those who do not play any sport. 40 respondents, i.e. children from a kindergarten in Zagreb between the ages of 5 and 6.5, participated in the research. Within the research, an affirmative hypothesis was put forward, which shows that there are differences in motor skills between preschool children who play sports and those who do not, in favor of those who play sports. This hypothesis was partially confirmed due to the fact that the child athletes showed better motor skills in 4 measured variables, namely: back bend polygon (MKPN), sit-ups in 30 seconds (MST30), standing long jump (MSDM) and hand tapping (MBTR). In the two measured variables, the results show that there is no statistically significant difference between athletes and non-athletes, namely: standing on one leg on a cube (MRSJNK) and torso forward bend (MFSR). Although it was shown in the two measured variables that statistically there is no big difference between athletes and non athletes, the results were still better for athletes, which proves that sports undoubtedly influence children's motor skills and that adults should encourage children whenever possible to enroll in sports or to any physical activity.
