Opis:
Introduction: The assessment and comparison of the precision and frequency of movement in épée fencers representing various sport classes, and the determination of the influence of three-year symmetrical and unilateral training on dynamic asymmetry. Material and Methods: The research was conducted in 60 female épée fencers, who were divided into four groups according to the sport class they represent (n= 15). In group I there were medalists of the World and European Championships, in group II - medalist of the Polish Championships. Group III and IV consisted of players who achieved successes at the Warsaw Championships. After three years of symmetrical training, the tests were repeated in groups III and IV. The tests were carried out using the Vienna Test System with the aid of the Motor Performance Series device (S2 test), which allows the assessment of coordination skills in terms of fine motor skills. Results: In the conducted research, significant differences in the asymmetry of the upper limbs in the aiming and tapping tests were found in all data groups. The differences in the tests obtained with the dominant and non-dominant upper limb confirm the greatest dynamic asymmetry in the female fencers from the Masters Class. After three years of symmetrical training in the experimental group and unilateral training in the control group, statistically significant differences were observed in all the trials performed with the dominant and non-dominant upper limb. However, in the experimental group of épée fencers, the dynamic asymmetry in the aiming indicators was lower than in the control group. Conclusions: Dynamic asymmetry in terms of the precision and frequency of movement was recorded in all studied groups. High-class épée fencers were characterized by the most significant difference between the results obtained with the dominant and non-dominant upper limbs, which is the result of long-term unilateral training. The three-year symmetrical training conducted in the experimental group had a positive effect on the precision and frequency of movement, however, it did not prevent the occurrence of dynamic asymmetry in the participants. The unilateral training used in the control group further increased the asymmetry of movement in the sportswomen.

Opis:
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.

New mathematical model which describes process of direct withdrawal beet of a root crop of a ground which is carried out under the action of vertical troubling forces and traction effort which are given to it by vibrating of digging up working body is constructed. The received systems of the differential equations, which decisions have enabled to find the law of movement of a root crop during its direct vibrating withdrawal.
Nowy model matematyczny opisujący proces bezpośredniej ekstrakcji buraków wyorywania ziemi, przeprowadzone w ramach działania pionowego odrażającego życie i wysiłek trakcyjnej, które zostaną przeniesione tutaj wibrujące wykopywanie ciało działa jest skonstruowany. Układy równań różniczkowych, które decyzja pozwoliła zdefiniować prawo przepływu upraw korzeni podczas bezpośredniego poboru wibracyjnej są odbierane.
