AnotationGait is a basic movement of human (Perry, 1992). Hu et al. (2016) the processes in gait are divided into two phases, the first phase is the firs 5 ? 6 months after the child start walk. In this stage occours speedy changes of kinematic and kinetics, the second phase lasting until the age of 8 tuning occurs of the gait pattern. The first mature gait becomes after 4 months independent walk (Hallemans et al., 2005). Step length, cadence and speed gait are influenced by maturation of the central nervous system and body growth up to 4 years, then remain constant and are similar to adults (Sutherland, 1997). Bernstein (1967) formulated coordination as the problem of mastering superfluously degrees of freedom (joints, body segments, muscles). Changes in coordination may be different in output, described by biomechanical variables, and in dynamic degrees of freedom, described as coordination and coordination variability of individual segments. The variability of dynamic systems is represents an important position in transition between gait cycles, motion stability, learning new motion and choosing optimal motion parameters. Provides random variations of motion and selected the most appropriate (Van Emmerik, Hamill & McDermott, 2005). Development gait is considered as a process leading to optimization of the gait cycle, symmetry and stability of the neural, muscular and skeletal system (Assaiante a kol. 2005). However, there is a question of whether there is a changes in coordination and coordination variability gait during ontogenesis in pre-school children and whether physical aktivity have influence of coordination and coordination variability gait to preschool children. The sample will be divided into 2 groups. The first group will be 2 and 3 years old children and the second group will be 6 years old children. In the first year of the project, will bw collect of kinematic data using the optoelectronic stereofotogrammetry method.
