The relationship between movement and rhythm is extremely important for developing children. Rhythmic capacity leads to a reduction in muscle fatigue, frees from unnecessary effort and optimizes movement by reducing energy consumption. Also, rhythmicity helps in developing most motor and cognitive skills. Upon entering the preschool age, the child begins to acquire a number of different skills more quickly, among them coordinated movement in rhythm. For the purposes of this work, the research was conducted in a kindergarten on two occasions, one month apart. It was conducted on a sample of thirty children of preschool age with two simultaneous kindergarten groups with different names ("Ježići" and "Krijesnice"). The goal of the research was to gain insight into the ability to acquire the skill of coordinated movement in the rhythm of preschool age children and to check possible differences in the speed of acquiring a sense of rhythm with regard to gender. Two hypotheses were set, the first that the results of the final measurements will be significantly better and the second that there will be no significant differences in the rhythmic coordination of children based on gender.
