Design of operator workplace of machining center
Kříž, Jan ; Pavlík, Jan (referee) ; Novotný, Tomáš (advisor)
The presented work contains the parameters and rules relevant for the design of the inter- face between the machining center and it's operator. All of information were obtained by search in scientific literature and technical standards and subsequently were sorted according to the elements to which they relate. The work contains the actual anthropometric dimensions, description of the interface elements with references to standards which relate to them. The study also shows an example of an optimized keyboard layout for machine tools and methods applicable to design the spatial layout of the workplace. In conclusion there is evaluate the state of currently available literature and technical standards.

Motor skills of volleyball and beach volleyball players depending on their anthropometric parameters
Hercogová, Simona ; Pokorný, Ladislav (advisor) ; Přibyl, Ivan (referee)
The thesis "Motor Skills of Volleyball and Beach Volleyball Players Depending on Their Anthropometric Parameters" discusses the distinctions in somatotypes of players of both sports. The thesis aims to define the influence of a somatotype for playing in each position. Furthermore, the thesis compares the differences in motor skills between beach volleyball and volleyball players. Nowadays, professional sports are characterized by growing pressure on athlete's performance. It leads to higher competition which lowers the differences between the individual athletes to minimum. As it gets more difficult for every athlete to be the best, room for science opens up in sport. For this reason, natural conditions of somatotypes and other anthropometric parameters play key roles. The aim of the thesis was to discover the differences in motor skills and somatotypes of beach volleyball and volleyball players. In the research, somatic and motor measurements were applied on players of the same performance categories. Thus, the thesis offers material that beach volleyball and volleyball coaches can later use in practise, for instance while spotting future talents, setting appropriate positions or creating game plans. Key Words Beach Volleyball, Volleyball, Anthropometric Parameters, Motor Skills

The comparison of different methods of body fat measuring by ensemble of adult women devided into five groups according to the BMI level
Šebková, Jana ; Matoulek, Martin (advisor) ; Svačina, Štěpán (referee)
Title: The comparison of different methods of body fat measuring by ensemble of adult women devided into five groups according to the BMI level. Objectives: The aim of this thesis is to compare values of gained percentage of total body fat by descriptive method such as bioelectrical impedance analysis and skinfolds measuring in comparison with "gold standard method" DEXA and to evaluate the usability of each method of body composition measuring by five groups of women, devided according to BMI level (in range 20-47 kg/m2 ). The purpose of this thesis is to find the most useful method especially for the overweight and obese women (BMI over 30 kg/m2 ) and to estimate the equation for the whole group. The other part of this thesis is the theoretical conclusion of the matters of body composition assessing and the importance of good knowledge about this topic for physiotherapists. Methods: The study was realizing from January of 2010 to March of 2011. There were 136 women, who were clients of Fitness center of VŠTJ Medicina Praha and jointed to the group voluntarely. The criteria of choosing the subjects into the study were: age 18 - 75 years, BMI 20 ≤ 45 kg/m2 , relatively healthy without accute disease. Women with cardiostimulator, pregnant women or nursing mothers were excluded. The monitored...

Metabolic syndrome and steroid spectrum
Pospíšilová, Hana ; Stárka, Luboslav (advisor) ; Hána, Václav (referee) ; Fingerová, Helena (referee)
Sex steroids influence the storing of fat, and differences in the distribution of fat are a typical secondary sexual characteristic. Androgens act on fatty tissues in males either directly through stimulation of the androgen receptor or indirectly through aromatization of the estrogen receptor. Androgens can be classified as aromatizable or non-aromatizable. Testosterone (T) is the main aromatizable androgen, while its metabolite dihydrotestosterone (DHT) is a non-aromatizable androgen that acts only through the androgen receptor. It is precisely this difference in having activity only through the androgen receptor that has given rise to the hypothesis concerning the differing effects of DHT and T on body composition, with DHT possibly being responsible for male-type fat distribution. As part of my post-graduate studies we analyzed the dependence serum levels of T and DHT on age, as well as changes in their ratio with age. Further, we sought relationships between aromatizable and non-aromatizable androgens and metabolic and anthropometric parameters. We also focused on following any changes in steroidogenesis in obese males. We showed that before puberty the dominant androgen is rather DHT than T, that the fDHT/fT ratio during the life of adult males is constant, and that there is no evidence of a reversal...

Anthropometric parameters as the factors affecting the performance of beach volleyball players
Hercogová, Simona ; Pokorný, Ladislav (advisor) ; Jahodová, Gabriela (referee)
This bachelor thesis called "Anthropometric parameters as factors affecting the performance of beach volleyball players"discusses the importance of anthropometry to evaluation of individual performances of beach volleyball players. Beach volleyball has become more and more popular. It is mostly due to new financial resources which have contributed to professionalisation of this sport; on the other hand, it has become more demanding. Hence, there is room for implementation of scientific methods, anthropometry is of particular importance. The aim of this thesis is to examine to what extent anthropometric parameters influence the performance of beach volleyball players. In this research, I employ chosen somatic and motoric measures which are later applied to beach volleyball players of same performance categories. Results of this research may serve as a practical material for coaches of beach volleyball or volleyball. Its particular use might be in the selection of appropriate playing partners or in the creation of training schedule.
