Angle in the joint and H-reflex
Stiborová, Pavla ; Otáhal, Jakub (advisor) ; Konopková, Renata (referee)
Title: H-reflex, depending on the position of the joint Aim: The aim of this study is to determine whether the position of the ankle joint influences the parameters of the soleus muscle H-reflex. We are interested in a change of amplitude, latency and threshold of the H-reflex. Method: To measure H-reflex, we have used surface elektromygraphy. We examined two different positions of the foot in probands lying on the bed on their stomach. The first position was with the feet out of bed, around 90 degrees at the ankle joint (rest position). At the second position, the foot moved the bed and was in position in plantar flexion. Stimulation were performed over the tibial nerve in the popliteal fossa. The response, we recorded the surface electrode over the soleus muscle. Results: By changing the position of the ankle from rest to plantar flexion there was no statistically significant changes in amplitude, latency or threshold of the H-reflex. In plantar flection, we found a reduction of Hmax/Mmax ratio, which is probably due to reduced excitability alpha motoneurons through reciprocal ihibition from stretched muscle of the leg. Keywords: H-reflex, soleus muscle, joint position, surface EMG

The Report to Education in Antiquity. Plato and his Conception of education.
STIBOROVÁ, Pavla
The paper deals with the Plato´s conception of education. It is divided into three parts. The first part includes the interpretation of Plato´s life, the survey of his dialogues and the influence of Socrates on the Plato´s life and philosophy. The second part deals with the very conception of education and it includes chapters on the perception of the child in antiquity, on the impact of society of education in Plato´s time. The third part is devoted to reference works of Plato ideas for future pedagogues. This part includes Plato´s supporters and his opponents. The objective of my paper is understanding of the fundamental aspects of the Plato´s life and his educational concept is one of the most important articles in the history of education.
