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.

Využití běžeckého wattmetru STRYD pro stanovení úrovně VO2max u vytrvalostních běžců
Bekr, Ondřej ; Kundera, Václav (referee) ; Pavelka, Jan (advisor)
Determining the limits of general endurance, critical power and maximal oxygen consumption is now a common part of the training process of professional athletes and their preparation to achieve the best possible sports results. Power is a very useful metric in cycling, but in recent years runners have also been trying to exploit its potential. Running power is only functional if it represents well the metabolic load of the organism. This thesis investigates the relationship between running power PO and oxygen consumption VO2, a representative of the metabolic load of the organism, in indoor and outdoor environments. Furthermore, thesis verifies the possibility of determining the VO2max level of runners using running power. The relationship between PO and VO2 is linear, for individual subjects the R2 is 0,95±0,07 in the indoor and 0,97±0,02 in the outdoor. For all subjects (TO) in the indoor the R2 takes the value of 0,67 and in the outdoor the value of 0,79. There was a difference of 1,2% (PO) and 3,7% (VO2max) between the values measured in the different environments. The model prediction from all TO in the indoor environment has an error of 3,5%.

Analysis of the dependence of selected ventilation and somatic parametres of adolescent footballers on the age and lenght of systematic training
PAŘÍZEK, Jakub
The aim of the bachelor thesis was to determine the values of certain ventilation and somatic parameters and to compare the results of adolescent categories U16, U17, U18 and U19 with the given standards. The footballers underwent measurements on a running ergometer in the form of a stepped run to the "vita maxima" and the Tanita BC 418 MA device at the beginning of the summer pre-season at the Laboratory of Load Diagnostics at DPSS, Univesrity of South Bohemia before the start of the 2021/2022 season. The examined somatic parameters included the BMI value and the proportion of muscle and fat mass. Ventilation parameters included maximum oxygen consumption/uptake, tidal volume, breath frequency, minute ventilation, and heart rate at the VO2peak. Footballers achieved optimal or above-average values for all parameters except the tidal volume and breath frequency, while the factual and statistical significance of the differences in values was proved for all parameters. The average of the values of the most important parameter VO2max was 59.17 ? 4.25 ml?min-1?kg-1 in category U16, 59.21 ? 3.57 ml?min-1?kg-1 in category U17, 58.44 ? 5.15 ml?min-1?kg-1 in category U18 and 59.05 ? 3.94 ml?min-1?kg-1 in category U19. The results of the work may point to above-average achieved parameters and may help to create focused training on the underdeveloped ones.

Comparison of results of spiroergometry on running and bicycle ergometer of elite regional triathletes
VÁŇA, Jan
The main aim of our work was to compare adolescent and adult elite triathletes from the South Bohemia region based on the results from the spiroergometry testing on the treadmill and bicyle. All of the tests were performed in the Lab of functional stress diagnosis at the KTVS PF JU. The testing parameters included the values of VO2max, tidal volume, minute ventilation, respiratory rate and the percentage of a body fat. Stress test were performed thanks to running ergomerer Cortex metacontrol 3 000 and a bicycle ergometer LODE Excalibrum Sport. The Tanita BC 481 MA is a bioimpendatory machine that was used to get informations about a body composition. One of the monitored values was the level of VO2max which was higher in adolescents than in adults. The values in the adults were 67,8 ? 6,3 ml.min-1.kg-1 on the bicycle and 69,2 ? 4,9 ml.min-1.kg-1 on the treadmill. In other monitored ventilation parameters, except a tidal volume on the bicycle, we measured higher values in the adults. The vaule of the VO2max was higher in the both categories and for this reason we suppose that triathletes are rather more runners than cyclists. The next thing we came up to is that the differences of the VO2max values are lower in the triathletes than in the runners and cyclists. The adolescent triathletes from the South Bohemia region have higher values of the VO2max than the adults despite their incomplete physical development.

Analysis of several-year preparation of endurance runner
ŠTEFAN, Rostislav
The aim of our bachelor thesis is to analyze multi-year annual cycles of endurance runner at the level of the best Czech runners. Specifically, we analyzed the competitor's diaries from the 2012/2013 season to the 2016/2017 season. Based on the evaluation of the training diaries and the results of the competitor, we had a task to identify the causes of the performance improvement and then find possible reserves in the training, we also had to suggest changes in the training plan leading to an increase of performance. To evaluate the data we used content analysis. We also used the comparative method for data processing. In the analytical part, we were examining individual training indicators and performance curves of the athlete. The most important endpoints were the training indicators, the runner's resulting times, and the VO2max values, which increased from a baseline of 65 ml?min-1?kg-1 to a maximum value of 85 ml?min-1?kg-1. In most cases, our results show an increase in performance associated with an increase in training load during tracking.

Analysis of the impact of a 10-day training camp at a higher altitude on performance of adolescent runners
NOVÁK, Daniel
Goal of this Bachelor thesis is to check, if there will be any changes of functional and biochemical parameters of the organism for medium and long length track adolescent runners during a 10-day training camp in high altitude around 1850 meters. Runners were subjected to functional laboratory examination both before and after the camp. All requisites were identical for both the control group and the runners who completed this camp. We were examining measured parameters of VO2max, resting heart rate, breath capacity, expiratory minute ventilation, pulse oxygen, respiratory rate, respiratory exchange ratio, heart rate during peak oxygen consumption and maximum watt performance. Most significant watched parameter was VO2max, where we saw an increase of 15,52 % from original 55,40 +- 7,73 ml-min-1-kg-1 to 64,00 +- 9,87 ml-min-1-kg-1 . Another one was resting heart rate, there was a decrease of 5,86 % for the runners after coming back to lowland compared to rates that were measured before the camp. Erythrocytes values increased by 2,38 %, haemoglobin by 2,69 % and haematocrit by 2,27 %. All these results show factual and statistical importance, the only parameter that didn't show any statistical importance was haematocrit. Result of our research confirmed, that 10-day training camp has a major impact on functional and biochemical parameters of the organism.

Regulatory measures for influencing aerobic fitness of middle-aged women
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...
