Analysis of Drivers' Responses to Complex Stimuli
Kaplánek, Aleš ; Ptáček, Petr (referee) ; Němejc, Jiří (referee) ; Kolíbal, Zdeněk (advisor)
This paper deals with the preparation, implementation, and basic assessment of the motorists’ response times to simple optical and complex – other than optical - stimuli. Driving tests conducted partly under regular traffic conditions and partly on a test track are completed with findings on how drivers react when they use their phones during driving. Knowledge of the actual technically achievable reaction time is necessary in performing analyses and consequent assessments of the causes and developments of road traffic accidents.

Influence of the reaction time on neuronal response amplitude after the uncommon stimuli in fMRI images
Klimeš, Filip ; Bartoň, Marek (referee) ; Lamoš, Martin (advisor)
The goal of my bachelor’s thesis is to provide basic idea of the functional magnetic resonance imaging. The theoretical part deals with general principles, methods of measurement and analysis of fMRI data. The partial and also key objective is to design ways of modelling reaction time within the concept of general linear model. The goal of the practical part was to become familiar with SPM toolbox and then to implement designed ways on group data. The implementation was carried out at two levels: preprocessing and analysis of measured data. Preprocessed data were subjected to the first level analysis and second level analysis. Next aim is to evaluate the results of both analysis and thus different approaches to the modelling of reaction time and its influence on neuronal response amplitude after uncommon stimuli in functional magnetic resonance images.

Analysis of time demandingness for solution of selected road traffic situations by drivers
Krejčiřík, Roman ; Bucsuházy, Kateřina (referee) ; Semela, Marek (advisor)
The presented diploma thesis deals with the analysis of driver time, which is needed for solving the chosen traffic situation in regular road traffic. The thesis aims to find out the duration, which drivers need for evaluation of chosen various types of intersections, and the duration which is needed to safely drive thru those intersections. Based on the theoretical part of this thesis, the experiment was proposed. This experiment was accomplished by real drive testing. The experiment took place in the city of Brno, with 10 participants. The purpose of the experiment was to obtain the required times for decision-making for 7 different situations in city traffic. Data were collected by eye tracker and afterwards, these data were evaluated and sorted by different categories and factors. The results were compared between the same intersections and also between different intersections. Obtained results give basic information about duration, which is needed for solving the situation. The shortest time obtained was 2,1 s.

Drivers reaction time analysis in regular road traffic
Florek, Matej ; Bilík, Martin (referee) ; Belák, Michal (advisor)
This diploma thesis focuses on driver`s reaction time in real road traffic conditions. The reaction time topic foundations are covered in the introduction as well as the motivation and brief application possibilities of the obtained results. The literature review is focused on history of developing different approaches of evaluation and terminology. For complex understanding it provides basic information about perception forms which are important parts of reaction time. The experiment was designed based on past studies review in order to get real data describing reaction time of chosen stimuli. Obtained data were analysed, partially processed values were compared with predicted results based on other researches, than integrated into general values of reaction time.

Comparison of reaction times between combat sport athletes competing in matches and technical patterns
Novotný, Mikuláš ; Třebický, Vít (advisor) ; Pavelka, Radim (referee)
Title: Comparsion of reaction times between combat sport athletes competing in matches and technical patterns. Objectives: The main goal of this bachelor thesis is to compare the simple reaction times between two disciplines (sports fighting and technical patterns) in Taekwondo (WT, ITF) and Karate (JKA, ČSKe). Methods: To collect the data, we used a purpose-built questionnaire containing questions about basic demographic information, martial art and its discipline, length of experience, achieved technical level, and self-rated reaction speed. We measured reaction times using a purpose-built test through PsychoPy3 and the Pavlovia platform. The entire participation took place on-line and was mainly distributed through advertisements on social media and contacting associations of the studied sports. A total of 112 people took part in the study. Results: We found no statistically significant differences in mean reaction times between the sports fighting and technical patterns. Further, reaction times were statistically significantly negatively associated with the length of experience and age. Keywords: reaction time, visual signal, combat sports, on-line

Physical profile of judo athletes and its changes due to body weight reduction
Coufalová, Klára ; Heller, Jan (advisor) ; Harsa, Pavel (referee) ; Vomela, Jindřich (referee)
Title: Physical profile of judo athletes and its changes due to body weight reduction Aim of work: The aim of this study was to determine the effect of intensive pre-competitive body weight reduction on body composition, anthropometric parameters, postural stability, reaction time, maximal isometric muscle strength and biochemical parameters in the blood of elite judo athletes. Methods: The work compares the results of laboratory testing at the beginning and at the end of body weight reduction. Nine male judo athletes (age 22.3 ± 2.4 years) from the Czech national team participated in the research. For laboratory testing we used bioelectrical impedance analyser InBody 720, anthropometric equipment, pressure plate FootScan, dynamometer and apparatus for measuring reaction times of Biomedical laboratory UK FTVS and equipment for the collection of capillary and venous blood. We created a survey to gather more information about pre-competitive weight loss, attended by 53 competitors (37 men and 16 women, mean age 23.7 ± 3.2 years) who practise judo, wrestling Greco-Roman and freestyle, boxing, kickboxing, thaibox, taekwondo or karate. Results: We found a statistically significant (p<0.01) reduction of body weight, average weight loss was 4.6 % (on average 3.4 ± 1.6 kg). This reduction was reflected in...

Identifying a genetic predisposition affecting sports performance, focusing on anaerobic activity of skeletal muscle activity
Balkó, Iva ; Kohlíková, Eva (advisor) ; Šimonek, Jaromír (referee) ; Zvonař, Martin (referee)
Title Identifying of genetic predisposition affecting sports performance focusing on anaerobic activity of skeletal muscle activity Problem Inborn predispositions of every individual are mainly influenced by the inherited genetic information in their DNA with the addition of external environmental factors. Based on the high variability of the inborn predictions in the form of phenotypic differences in the anatomy or physiology of an individual, it can be deduced on the connection between genetics and a specific sport talent. According to current scientific knowledge, anaerobic performance of the skeletal muscle tissue seems to be more genetically influenced. Anatomic and functional properties of the skeletal muscle are mainly influenced by genes, which have effect on the muscle fibre structure, blood storage, metabolism, neurotransmission, and muscle regeneration, etc. Fencing is a complex sport discipline where predispositions to speed and dynamic force play a key role. The sport performance in fencing, regardless of the type of weapon, is directly dependent on the interactions between the reaction of the fencer to the surrounding stimuli (visual, tactile), accuracy, tactical and technical skills, level of anticipation and overall physical a psychological readiness of the fencer. This work is...
