摘要：The aim of the paper was to determine the characteristics of sprinting in boys and girls of the preschool and and early school age, as well as to identifythe differences in parametres of running dynamics between boys and girls. The research has been conducted on a sample of 133 boys and girls of 3 to 10 years of age. The times of sprints on each five metres in a 50 metres lap and the time of starting reaction were measured with a system for electronic measurement. The basic descriptive parametres have been calculated. Gender differences have been analysed by the univariate analysis of variance. The obtained results showed that the time in 50 metres sprinting and the time of the starting reaction were shortened as the subject is older, while the speed following the start and the maximum speed increased with age. The lowest maximum speed is obtained in the three and fouryear- olds. The highest speed is obtained in the nine and ten-year-olds. The analysis of differences between boys and girls of pre-school and early school age has shown are no statistically significant differences in kinematic parametres of sprinting according to the gender.
