Sažetak
Since sprinting is the quickest form of human motion, the object of this research is the structure of sprinter’s running with children of an earlier school-age. This research’s aim has been to determine the relations between kinematic parameters of sprinter’s running and specific motor abilities with girls and boys of an earlier school-age. The sample of examinees has been made by 150 male and female pupils (70 male and 80 female pupils) belonging to the first and second grade of a primary school in Pula, Croatia. The sample of variables consists of variables which determine the kinematic parameters of sprinter’s running in the phase of maximal running speed (step frequency, step length, the duration of contact with the pad and the duration of the flight phase), those which determine the 50 metres running time and those which determine the specific motor abilities (the Counter movement jump test and the Three connected jumps test). The average boys’ running time on the 50 metres lap has been 10.098 s, while girls have achieved the time of 10.588 s. Regarding the maximal running speed on the 50 metres lap, boys have showed a higher frequency and lower step length as well as a shorter duration of contact between the foot and the pad and a shorter duration of the flight phase than girls.The forward stepwise regression analysis has been used to define the relations between specific motor abilities and kinematic parameters of sprinter’s running. Results have showed that the boys’ 50 metres running time (KT50) is highly connected to the variable of three connected jumps (MTPS), while the girls’ 50 metres running time is connected to the variable jump from a static position with preparation (MCMJ).
