Králová, Kateřina ; Bunc, Václav (advisor) ; Čechovská, Irena (referee)
Title Regime intervention to influence aerobic fitness level of middle age women Objective The aim of the work is to evaluate the effect of two-month physical intervention on the aerobic fitness level of middle-aged women and the influence of this intervention on the change of the body composition of individual study participants. Methods The tested group consisted of 5 middle-aged women with a sedentary occupation and no regular physical activity. The evaluation of their aerobic fitness and body composition was performed before the start of the intervention. These values were compared to the results of the same tests after the intervention. The values of VO2max measured before and after the intervention were used for the evaluation of aerobic fitness. The regression equation, based on the results of 2 km walking test (part of the UNIFITTEST 6-60), was used for the calculation of VO2max. The methods of bioimpedance (using the portable device Body stat 1500) and anthropometric measurement (body high, weight, circuits) were used for determination of body composition - mainly % FFM and% BF. The physical intervention itself was focused on walking for two months period. The form was used for monitoring of intervention individual exercise units. The group of middle-aged women performed the prescribed...

Comparison of results of spiroergometry on running and bicycle ergometer of athletes with different specialization
MARKO, David
A choice between a running or bicycle ergometer is not possible in every laboratory. Significant differences may appear in measuring results of ergometers with different load specificity. The aim of our thesis is to find out about the differences of values during the spiroergometric test at the running and bicycle ergometer in sportspeople with different specialization, adolescent categories of mountain cyclists and medium and long track runners. To carry out all the testing, the Functional Load Diagnostic Laboratory belonging to the Department of Sport Studies at the University of South Bohemia. All cyclists and runners underwent both tests during three days having an equal physical condition. The tested parameters included the VO2max value, breath volume, minute ventilation, breathing frequency, maximal heart frequency, and maximal watt performance. Our results proved significant differences of all examined parameters in runners. There was a significant difference in cyclists´ results noted in the following parameters: VO2max, breathing volume, minute ventilation, and watt performance. The average values of the most important parameter, VO2max, in runners, was equal to 60,6 ? 4,24 ml.min-1.kg-1 while running, and 56,0 ? 5,34 ml.min-1.kg-1 while cycling, however, cyclists reached the value of 56,6 ? 5,16 ml.min-1.kg-1 when running, and 61,30 ? 4,47 ml.min-1.kg-1 when cycling. The results of our thesis have proven factually as well as statistically significant differences of measuring results in both running and bicycle ergometer, depending on the type of exercise.

Analysis of the influence of ski training in the first year of the study program PE and Sport at high altitude on the selected students' fitness requirements
KŘÍŽENECKÝ, Daniel
This thesis analyzes the physical predispositions of students from the first grade of the physical education who attended a ski course. This course took place in France. This fact is quite important for the thesis because the course took place in a higher altitude. The main aim of the thesis is to compare results of tested probands before and after the course. At first, there was an information meeting where we provided more information about the aim of this thesis and about the testing. After this meeting we went to KTVS laboratory where the first measuring happened. After that all probands and other students left for the ski course to France for a week. The accommodation was in an Alpe d´Huez center which is situated 1860 meters and the highest point of it which is 3330 meters above the sea level. Probands were practicing in very high altitude all week. In this thesis we also look at how hard it is to work in this altitude, what kind of advantages and disadvantages it might have and which danger might come up. It is also necessary to think about the process of how probands should prepare themselves not to underestimate anything. The second measuring happened after the return to the Czech Republic. It also took place in KTVS laboratory. After the measuring we started analyzing all measured data of probands. We compared this data. After that we realised what this course brought to the students. We wanted to know what happens in following parts: body composition, Wingate test, spiroergometry and spirometry. In each part we were interested in some specific parameters that are related to this topic. We included specific parameters like: body fat, muscle mass, body water, maximum performance, average performance, maximum 5 seconds performance, fatigue index, VO2max, oxygen pulse, minute respiratory volume and vigorous vital capacity.

Analysis of changes in endurance assumptions of ice hockey players during summer preparatory period
HOLICKÝ, Tomáš
The bachelor thesis deals with the comparison and evaluation of VO2max test results and body dimensions before and after the summer preparation for players of the ice-hockey team. We compared and evaluated the results. In total, 29 players were tested. This is one ice-hockey team where are different age groups of players. We tested the players in a functional diagnostic lab on a cycling ergometer. We have identified values that determine the maximum oxygen consumption of VO2max in muscle work, anaerobic threshold (ventilation). In the lab, we also had to measure the basic somatic dimensions of each individual on Tanita (foot scale) before testing. The practical part characterizes the test files, the procedure, the test results and the used test devices. Measured and resultant values are reported and processed in tables and graphs that were created in Statistics 12. The thesis confirmed the expected increase in VO2max at the end of the preparatory period as well as an increase in the percentage of muscle mass associated with body fat loss and weight loss.

Stehlík, Jiří ; Frýbort, Pavel (advisor) ; Kokštejn, Jakub (referee)
Title: The effects of the application of insoles in sports shoes on aerobic capacity of soccer players Objectives: Effects of insoles Bootmatetsi on aerobic capacity of football players. Methods: The research sample included a soccer player in the U16 category (n = 19). The Yo-Yo Intermittent Recovery Test Level 1 was used to verify the interventional effect of the Bootmatetsi insoles. For the subjective perception of physical activity during the pretest and posttest was used a 15-degree Borg scale of 6 - 20. A five-point Likert scale was used to evaluate the comfort of Bootmatetsi insoles. The data was processed using Microsoft Office Excel 2010. Results: The application of Bootmatetsi insoles to football boots has provided a significant improvement in aerobic performance compared to original insoles (d = 1.1). Performance improved on average by 24%, i.e average improvement VO2max by 2,43 ml.min-1.kg-1. At the same time, research group claims that Bootmatetsi insoles have been rated as comfortable. Keywords: insoles, Bootmatetsi, aerobic capacity, VO2max

Kotas, Jan ; Malý, Tomáš (advisor) ; Bunc, Václav (referee)
Title Analysis of the endurance indicators in selected tests in relation to continuous and intermittent loading Objectives The aim of this study was to examine the accuracy of the prediction formulas for indirect estimation VO2max from performances in the field tests. The criterion for comparing estimated values were results from laboratory spiroergometry test. Methods Ten physically active males (24,5 ± 2,5 years, 179,5 ± 6,2 cm, 75,8 ± 4,9 kg, BMI 23,5 ± 1,3 kg/m2 ) performed four different test sessions. Laboratory treadmill test was used for the direct measurement of the maximal oxygen consumption (VO2max) and three field tests for indirect estimation of the VO2max (Cooper test, Yo-Yo Intermittent Recovery Test Level 1 and 2). All the performances from field tests were calculated using prediction formulas. Results Directly measured values of VO2max during laboratory testing were in average 58,24 ± 2,77 ml.kg-1 .min-1 . Indirectly estimated values of VO2max from performances in the Cooper test were in average 61,15 ± 3,73 ml.kg-1 .min-1 , in Yo-Yo IRT1 52,46 ± 2,51 ml.kg-1 .min-1 and in Yo-Yo IRT2 53,19 ± 1,56 ml.kg-1 .min-1 . There was found large positive correlation between laboratory testing and Cooper test (r = 0,76). This correlation was the only one statistically significant. The...

Paroulek, Martin ; Bunc, Václav (advisor) ; Česák, Petr (referee)
Title: Field tests relevancy (equipollence) of endurance predisposition of professional footballers. Made by: Bc. Martin Paroulek Supervisor: Prof. Ing. Václav Bunc, Csc. Aims: Contribute to solve problems with defining the level of endurance predisposition of professional footballers. Methods: 10 professional footballers were tested. Their average age was 19,1±0,9 years, average weight was 69,2±2,5 kg and average height was 178±4,2 cm. Data was obtained from three functional load tests. Data was processed by means of correlative analysis. Assumed level of equipollence among load tests was defined 0,7. Results: We haven't found significant relation betweeen measured figures of VO2max laboratory load test and measured figures of field 2 km run test. We even haven't found significant relation between measured figures of VO2max laboratory load test and measured figures of field endurance 20 m shuttle run test. As we can see from the results, field tests cannot be considered as adequate compensation of laboratory tests. More research is needed at this field of survey to be able to confirm it or adjust it. We are aware of limits of our survey and its value of notice, for example number of probands etc. It was confirmed that 2 km run test has higher level of equipollence (0,41) in laboratory load test...

Comparison of two analysers of respiratory gases by paired examination of the same persons
Moravcová, Martina ; Vilikus, Zdeněk (advisor) ; Majorová, Simona (referee)
Title: Comparison of two analysers of respiratory gases by paired examination of the same persons. Resource: The basic assumption of laboratory measurements is precision of devices. The aim of this study was to determine if the values of spiroergometric parameters measured at the same load on the same subjects by two different devices are comparable. We compared the respiratory gas analyzer Kardiospirox (Junkalor, CR) and Oxycon Delta (Jaeger, Germany). Methods: We studied 11 subjects on both devices on the same day. The intensity and duration of load were chosen to be repeatable in the same quality after a short rest. We measured the basic spiroerometric parameters at rest, during exercise 20W, 50W, 100W and 150W for men and at rest, during exercise 20W, 40W, 80W and 120W for women, always at steady state. For statistical comparison method we used Student's paired T test. Results: Heart rate (HR), oxygen consumption (VO2.kg-1 ), ventilatory equivalent (VE/VO2), breathing frequency (DF), respiratory exchange ratio (RER) did not differ significantly. Pulmonary ventilation (VE) and expired carbon dioxide (VCO2.kg-1 ) were significantly different. The reason could be that the sensor for ventilation of Oxycon works with inhaled and exhaled air while Kardiospirox works with just exhaled air....
