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.

The difference in kinematic and kinetic parameters of running using running shoes, barefoot and shod
Vyhnálek, Vojtěch ; Gryc, Tomáš (advisor) ; Červinka, Pavel (referee)
Title: The difference in kinematic and kinetic parameters of running using running shoes, barefoot and shod Objectives: The aim of this bachelor thesis is to analyze the kinematic and kinetic parameters of running using different types of shoes. We tested a sample of four probands aged 20-25 years male. Using applied clusters, we examined the differences in individual runs. Methods: The experiment was attended by 4 runners (men only) who completed a monitored run on a 3D running ergometer at several speeds. A CODA Motion System 3D kinematic analyzer with the appropriate ODIN software was used to evaluate the kinematic parameters, and a 3D running ergometer with implemented power plates and h / p cosmos designed software was used to evaluate the kinetic parameters. The measurements were one-time. The obtained data were processed in Microsoft Excel 2019, where the tables used in this work were created. Results: All subjects demonstrated an immediate change in technique during the transition from running shoes to minimalist shoes and then barefoot. The most significant changes took place in the tread angle, the ankle angle, the cadence of the steps and the force produced by the impact. However, changes in the monitored parameters did not lead to the correct running technique in barefoot shoes, which...

The Effect of Alcohol Ingestion on Maximal Treadmill Performance
Smrčková, Zuzana ; Strejcová, Barbora (advisor) ; Česák, Petr (referee)
Title: The Effect of Alcohol Ingestion on Maximal Treadmill Performance Objectives: The aim of this study was to assessed the effect of alcohol consumption before sport performance on the maximal running test and values of respiratory parameters. Methods: This study attended 7 girls age 21,3 ± 1,0 years which are active in sports. They had been running at the treadmill first time after intake of juice with alcohol in relation with their fat free mass and secondly only after intake of juice. This is called Switch replication design. Independent variable was ingestion of alcohol and dependent variables were maximal relative oxygen consumption, heart rate, minute ventilation and respiratory exchange ratio. Alcoholic history of each participant was detected. For this study were used treadmill ergometer Quasar (Cosmos, Germany), the metabolic analyser Metalyzer (Cortex, Germany) and the sporttester Polar. Results: Paired t-test was used for evaluation of the results. The measured values were not statistically significant with the level of significance 0,05. The measured values were individually evaluated in the same time and increase of minute ventilation was confirmed at 5 tested girls otherwise the effect of alcohol on maximal relative oxygen consumption and heart rate was not proved. The alcohol did...
