Children's 50 metres running dynamics

The aim of this research is to determine the 50 metres running dynamics with children of a younger school age, as well as the differences in parameters of sprinter’s running dynamics between girls and boys. The research has been conducted on a sample of 150 girls and boys of the first and second form of an primary school from Pula. The time of the start reaction and the time of sprinter’s running on each five metres on a section of 50 metres have been measured with a system for electronic measurement. The basic descriptive parameters have been worked out, while the differences between girls and boys have been analyzed by the univariant analysis of variance. The results for the segment speeds with boys and girls show that 50 metres running with children of a younger school age can be divided into three phases: acceleration (start acceleration), achieving and keeping the highest running speed and deceleration (crossing the finish line). The analysis of differences between girls and boys of a younger school age has shown that there are statistically significant differences according to sex.
