DEPENDENCIES OF SPEED ABILITIES AND PHYSICAL DEVELOPMENT OF CHILDREN AT THE AGE OF 6–7 YEARS

Abstract In this article, we present the results of selected parameters of the running speed of young school children. The aim of this research is to determine the dependence of parameters of speed abilities and physical development of 6 – 7 year old children. The sample consisted of 67 probands (42 boys and 25 girls) with a decimal average age of 6.72 ±0.3 year. We used the test 4 x 10m shuttle run with changes of direction for diagnostics of running speeds. We used the test of lower-limbs frequency in 6s to find out the parameters of movement frequency. We established basic somatic parameters: body height, body weight, BMI. All obtained results were compared with each other and evaluated using correlation analysis. We stated that in somatic parameters high statistical dependence was recorded (p < 0.01), which we consider as a natural developmental indicator. In the group of girls, we recorded a slightly shorter contact time with the pad; however, a significantly longer flight time with single stride cycles. In intrasexual comparison, we recorded statistical significant difference in flight time and in stride frequency (p < 0.05). Boys achieved a higher stride frequency and a shorter flight phase, so they also achieved a higher number of step cycles. In the group of boys, we recorded statistical dependence (p < 0.01) between a running speed with changes of direction and stride frequency
