In this paper we present the results of the parameters of body composition in children on early school age. The sample consisted of 60 probands (40 boys and 20 girls) with a mean age by the decimal 6.73 ± 0.3 years. To determine body composition parameters were used for direct analysis of segmental multi-frequency bioelectrical impedance using the InBody 120 (Biospace Co., Ltd .; Seoul, Korea). All the results of measurements, we mutually compared and evaluated using statistical methods. The parameters of body composition was recorded intersex differences, but not statistically significant. Statistical differences were observed in the total body water (TBW) and the level of the basal metabolic rate (BMR). The parameters showing the state of nutrition, protein mass (PM) and the mineral mass (MM), we also confirmed the statistically significant differences intersexual. Somatic indicators of significant statistical dependence is found between body height and weight, as well as between body weight and body mass index, which will be shown ontogeny is assessed as a natural developmental indicator. The same statistically significant dependence was recorded also in the analysis parameters obesity parameters of active body mass and nutritional parameters.

The study presents the results of general physical performance among 3rd grade pupils at an elementary school on Ďumbierska street in Banska Bystrica. Results were gained through the application of selected tests and EUROFIT and UNIFIT [5; 2]. The experimental group consisted of 16 subjects (boys), aged 8 – 9 years, who attended athletics preparation within the "IAAF Kids' Athletics" program. The control group accounted for 18 subjects (boys) ofthe same age. The research period lasted nine mesocycles from 15th October 2014 to 17th June 2015. All the results obtained in the input and output measurements were mutually compared and evaluated using statistical methods. The output measurements in the experimental group compared with the control group experienced statistically significant changes at p ≤ 0.05 in all tests performed. Effect size was confirmed in tests on two medium effects and two large effects.

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.
