Gymnica PG - 105--111 VI - 35 IP - 2 IS - 23364912 AB - The aim of this research is to determine whether there are distinctions in runs among five and a half year old boys and girls. The research is based on studying 80 girls and 64 boys from seven kindergartens in Slovenia. The following five measurement methods have been used in our research: a 10-meter run, a 150-meter run, a 10-meter run with a flying start, 4-times 5-meter run, and a 300-meter run. The results of the t-test indicate a statistically characteristic difference among boys and girls in 300 m run test results only, that is, a method used for measuring aerobic endurance. Other motor skills results have shown that there are no statistically characteristic differences among boys and girls. It is important that sport activities for boys and girls are organized for both groups of children equally. Especially girls must take part in a variety of running exercises in order to increase their aerobic endurance. They should be encouraged to take part in a variety of games which require activating the energy component of movement. Based on the results of this research we can say that physical education (PE) of preschool children should be planned regardless of sex and the PE program should be the same for both boys and girls.
