10.5937/timsact8-5942 = Effect of programmed strength training on explosive strength of lower extremities in children aged 11 to 14 years

Vertical jumps are an integral part of many sport activities. There are several factors that affect the athlete's jumping ability: strength, force and acceleration that occur when we jump. The jump is a complex and more articulated activity that requires not only strength, but great power as well. The main types of training to increase explosive strength are plyometric training and myogenic training with weight load on the lower extremities. The aim of this study was to determine the effect of myogenic training with weight load on explosive strength of the lower extremities. The first group is the control group (K), while the second group is an experimental group (E), each consisting of eighteen respondents. By Using the Myotest and performing the squat jump (SJ), the Height, Power, Force and Velocity were determined. The programme of power lasted for six weeks, twice a week for up to 60 minutes. We conclude that there is a statistically significant difference between the final and initial measurements in the experimental group, the multivariate level sig = 0.000. Increase in jump height ΔHeight = 3.28 in cm, force ΔForce = 4.68 in N/kg, the strength ΔPower = 6.18 in W/kg, the acceleration ΔVelocity = 21.8 in cm/s. The results of this study show that myogenic training with weight load has a positive impact on the explosive power of the lower extremities. This research was carried out against children aged 11 to 14 years, so we cannot say with certainty that this type of programme can have identical effects on athletes.

Clinical and immunological aspects of a pathology newborn at genital chlamidiosis of a mother, which were revealed during pregnant

A role C.trachomatis infection and its possible consequences in puerperal period was investigated at 48 normal bom children and their mothers. The first group was 19 children and their mothers with normal tendency of early puerperal of period; the second group accordingly 28 mothers and 29 their children (one twins) with various functional violations. The 3-th group check of 16 healthy newborn and their mothers with normal current of pregnancy and sorts. In all groups a content C3, C3a of components complement, levels Ig A, M, G, circulatting immune complexes was studied.In the 1-st gr. C.trachomatis was detected only at one mother and was not detected at the children; in the 2-th gr. Accordingly at the 4 and the 5; in the 3-d gr. C.trachomatis in pairs Mother - children were not detected. Gross infringements in the immune system of the children were placed at chlamidiosis, and also heavy consequences at intrauterine infection G. trachomatis.
