Sádecká, Kristýna ; Malá, Lucia (advisor) ; Šteffl, Michal (referee)
Title: Changes in motor skills during ontogenesis in young children of schoolage. Objectives: The aim of the work was to identify changes in movement abilities during ontogeny in sports children of younger school age. Methods: This work is processed by the method of data analysis, which we drew from the available literature, documents and professional articles. We also used the method of comparison, which was used to compare the data with the data we obtained from the elementary school Benešovo nám. and further compared them using graphs and tables. The research from the obtained data is carried out from the first stage of primary school, specifically from the 2nd, 3rd and 5th grade, and consists of tests for long jump, sprint for 60 m and throwing a ball. Here we used basic statistical characteristics such as arithmetic mean, standard deviation. Results: As a result of the work, the first hypothesis of non-linear change in the 60m run test between 3-5 was not confirmed. class. For the second hypothesis, smaller gender differences in the development of speed skills than in strength skills were confirmed. By evaluating for practice, we can say that children's motor skills change and it is important to focus on them individually. The development of individual abilities is very important and the...

Changes in opioid signalisation during the ontogenesis.
Hoľuková, Martina ; Hejnová, Lucie (advisor) ; Škrabalová, Jitka (referee)
Opioid receptors interact with opiate compounds, causing the inhibition of neuroexcitability. The activation of signaling pathway of opioid receptors plays crucial role in the treatment of chronic and cancer pain. Summary of the general knowledge about opioid receptors and about the development of tolerance is in the first part of this work. Next part of the thesis concerns on ontogenesis of opioid receptors and other components related to the opioid signaling pathways as age seems to have an immense influence on molecules within and related to the opioid signaling. Finally, last part of this work collects data about the influence of morphine during ontogenesis as morphine is one of the most used opiate compound used in clinical treatment. Key words Opioid receptor, signalization, ontogenesis, addiction, tolerance, morphine
