Comparison of physiological parameter data generated by the Metalyzer 3B in the laboratory and the Metamax 3B for use in field research
Kříž, Tomáš ; Nohel, Michal (referee) ; Chlíbková, Daniela (advisor)
Increasing quality of the sport performance creates demands related to sports data acquisition which occurs in the natural environment. Such demands are then placed on the equipment manufacturers which need to adapt and adjust equipment for artificial as well as the outdoor environment. Furthermore, required equipment must be substantially reduced in terms of its weight as well as the size to minimize possible interference with the outdoor conditions. The remaining question is to which extent such adjustments influence the validity of the data inquiry and whether laboratory testing should be prioritized before outdoor testing. This thesis aims to provide a comparison between two oxygen consumption analysers across the unified evidence-based testing protocol. The first half of the testing is made with Metalyzer 3B (laboratory-based equipment), and the second part of the testing is made with Metamax 3B (outdoor-oriented equipment). Both analysers are produced by the Cortex company. The theoretical part of this project introduces the underlying theory of the oxygen consumption analysers and presents various methods used for the establishment of the VO2max. The practical part includes the measurements of set parameters on both devices with an identical test protocol. The t-test was used to prove statistical significance between Metamax 3B and Metalyzer 3B. Results of statistical analysis (V'O2 p = 0,54; V'CO2 p = 0,087; SF p = 0,49; V'E p = 0,2; DF p = 0,28; time p = 0,59) within the range of 95% confidence intervals.

The Study of Conditions for Sport in Chosen Enviroment
Votoupal, Tomáš ; Chlíbková, Daniela (referee) ; Korvas, Pavel (advisor)
This thesis deals with conditions for sport and physical activity in Trebic. The most important tools for processing the status quo analysis, comparison of data primarily from municipal budgets, and finally carried out a survey on the conditions of physical activity. Carried out the research, I found that the city of Trebic has on its size and population, good conditions for sport and physical activity, it can be judged from the number of sports facilities and based on increasing amounts on sport and investment in sports facilities. The quality conditions and also reflects 86% positive opinions on the conditions for physical activity that emerged from the survey.

Validity of the VO2 Master Pro device for maximal oxygen consumption prediction and the measurement of resting metabolism
Goldschmidt, Tobiáš ; Nohel, Michal (referee) ; Chlíbková, Daniela (advisor)
Measurements of maximal oxygen uptake and resting metabolic rate are one of the most important things in testing athletes and madical patients. For these measurements are used breath analyzers. These analyzers are usually non-portable costly devices. VO2 Master Pro is on the other hand portable breath analyzer with much lower prize. It is biggest disadvantage is that it contains only O2 sensor and not CO2 sensor as madically aproved devices. Aim of this study is to determinate validity and difference of measurements between VO2 Master Pro and reference device for measuring maximal oxygen uptake and resting metabolic rate. Difference for measuring maximal oxygen uptake was 4,15 ± 4,41 %. For measuring of resting metabolic rate difference was 41,20 ± 11,44 %. For measuring of maximal oxygen uptake is VO2 Master Pro valid but for measuring of resting metabolic rate it is not. It was also confirmed, that size of measured value have non-linear corelation with size of difference in measuring maximal oxygen uptake.

Study of Conditions for the Development of Cycling in the City of Brno
Matička, Tomáš ; Chlíbková, Daniela (referee) ; Peričková, Lucie (advisor)
Bachelor thesis deals with the cycling conditions in the city of Brno.The first theoretical part is dedicated to the advantages of theurban traffic on a bicycle, the possibilities of further development and funding. The second part of the work analyzes the current conditions of cycling transport in Brno and the society use of routes. The last part of the thesis contains a custom proposal for the implementation of cycling routes in the selected location,which could help expand the cycling route network in Brno.

Validity of predictive equations for determining resting energy expenditure
Fabián, Patrik ; Korvas, Pavel (referee) ; Chlíbková, Daniela (advisor)
This bachelor thesis deals with the validation of predictive equations to determine resting metabolic rate. The objective of this bachelor thesis was to compare individual predictive equations for determining resting metabolic rate with self-measurement using indirect caloriemetry and to establish a own procedure for predicting resting metabolic rate. The evaluation of each predictive equation was based on statistical analyses. Based on statistical analyses, it was found that the available predictive equations underestimate resting metabolism by an average of 20 % of kilocalories per day compared to the value measured by indirect calorimetry. Machine learning was used to determine the actual procedure for predicting resting metabolic rate, which was then presented using the user interface. The following testing showed that the neural network for predicting resting metabolic rate provides more accurate results compared to the available predictive equations.

The utilization of isokinetic dynamometer for the measurement and evaluation of muscle strength of lower limbs in athletes
Přidalová, Tereza ; Janoušek, Oto (referee) ; Chlíbková, Daniela (advisor)
Izokinetická dynamometrie je moderní metodou pro hodnocení svalové síly. Nejvíce se využívá pro posouzení tréninkového efektu během určitého období a pro rehabilitační účely. Kliničtí lékaři, vědci a fyzioterapeuti obvykle využívají pouze základních parametrů pro vyhodnocení svalové síly. Cílem této práce je tedy navrhnout alternativní přístup pro interpretaci dat a předložit možné využití a limitace této metody. Byl měřen moment síly v kolenním kloubu a následně provedena datová analýza. Patnáct parametrů je využito pro vyhodnocení dat. Moment síly byl porovnán mezi profesionálními sportovci (muži: 111.1 ± 51.0 [Nm/kg], ženy: 99.6 ± 90.8 [Nm/kg]) a amatérskými sportovci (muži: 146.2 ± 40.1 [Nm/kg], ženy: 45.3 ± 14.6 [Nm/kg]). Vztah byl pozorován mezi parametry úhlové pozice maxima a dobou od dosažení maxima do konce pohybu (flexe: = 0.65, extenze: = 0.71) a mezi úhlovou pozicí maxima a poměrem vykonané práce před maximem (flexe: = 0.91 extenze: = 0.86). Parametr práce v submaximální oblasti byl vyšší pro extenzi (median= 3.0 J) než pro flexi (median= 2.6 J).

The analysis of biochemical and hematological data in athletes
Molnárová, Monika ; Korvas, Pavel (referee) ; Chlíbková, Daniela (advisor)
This thesis is focused on blood and urine analyses of runners after the competition. It describes the principles of analysis and laboratory testing not only in laboratories, but also in terrain conditions. The thesis includes statistical testing and evaluation of hematological and biochemical parameters. With the use of Spearman correlation coefficient are determined the relations between the parameters. The goal of the thesis is finding a way to predict biological parameters by using a group of other parameters. In the practical part of the work is described the algorithm for prediction with Neural network Toolbox the network testing results and other ways to improve the prediction algorithm.
