I ABSTRACT Title: Kinesiological analysis of upper limb punch strike in sports karate. Aim of work: The aim of this thesis to describe and characterize the muscle involement in direct punch strike in karate. Then compared with the exercises, which are characteristic to karate - strikes with resistence and push-up exercise. Methods: Work is processed by a comparative analysis of selected movements based on the determination of muscle activation. The surface electromyography method synchronized with video and accelerometer was used in this work. Results: The result is describtion of selcted movements on the basis of muscle activation and function of selected muscles. The prove that the forearm extensors are activated as the last of the selcted muscles was managed. On the basis of karate technique and anatomy we confirmed important role of forearm extensor by direct punch in karate. The difference between onset time muscle activation by strikes and push up was found. Maximum speed of acral part of the upper limb by direct punch was established. Keywords: Electromyography (EMG), karate, direct punch - gyakucuki, accelrometer

Prague: Charles University, 2nd Faculty of Medicine, Department of rehabilitation and sports medicine, 2015. 91p. Supervisor MUDr. Josef Kraus, CSc. Abstract The theoretical part of this thesis briefly summarizes the findings of developmental dyspraxia and briefly characterizes different diseases encountered by tested subjects from a test sample of children with specific abnormalities, neurofibromatosis type 1 and Asperger's syndrome, and explores their relationship with developmental dyspraxia. The possibility of using dance therapy is also mentioned. The practical part is focused on evaluating the level of motor skills of children with specific abnormalities and children's rock and roll dancers using the Movement Assessment Battery for Children 2. Another objective is to determine whether the level of motor skills correlates with the level of attention tested by the Test of attention d2. The final goal is to assess the degree of physical activity of rock and roll dancers using the accelerometer ActiGraph GT3X. We confirm the presence of motor difficulties of children with specific abnormalities, however we did not confirm...

Bibliographical identification Title of Bachelor work: The size and differences in physical activity in the weekly mode in adolescent soccer players on performance level Place of work: UK FTVS Author: Bc. Michal Hojdar Field of study: Physical education and sport Head of work: Mgr. Jakub Kokštejn, Ph.D. Defence year: 2015 Generalization: This thesis is focused on the analysis of physical activity weekly regimen of adolescent soccer players at performance level who practice regular physical activity. The primary objective is to determine the differences in the size of physical activities in the category of younger and older adolescents, and then compare the results obtained with each other and with health recommendations for these ages. Younger adolescents consist of U16 and U17 players in age from 15 to 17 years. Older adolescents include soccer players U19 aged between 17 and 19 years. Research is aimed to the players of football club FC MAS Táborsko. To determine the size and composition of physical activity was used accelerometer ActiGraph GT3X. Obtained data are processed in the program ActiLife Lifestyle Monitor Software. To ensure that the measured values are relevant and comparable, were used statistical methods of calculations, such as arithmetic mean and standard deviation. For clarity and ease of...

Title: The level of physical activity and physical fitness in school age children Author: Bc. Luboš Soldát Head of work: Mgr. Jakub Kokštejn, Ph.D. Objectives: Chart the level of physical fitness and level of physical activity at younger school children. Discover the strength of the relationship between physical fitness level and physical activity level at children of this age. Methods: The research group consisted of third, fourth and fifth grade pupils (n = 77; 9.8 ± 0.6 years). To determine the fitness level, the Unifittest (6-60) was used and weekly measurements using Actigraph GT3X accelerometers were used to determine the level of physical activity. Results: The average daily time spent on activities at medium to very high levels of physical activity exceeded the recommended health standard set at 60 minutes a day. The average daily number of steps did not exceed the recommended health standard of 11000 steps per day. At physical fitness tests 29 % of children achieved to average results, 36 % of children to below- average results and 35 % of children to above-average results. The average amount of subcutaneous fat was measured by 42 % of children, below 8 % of children and above average of 50 % of children. The strength of the relationship between the level of physical fitness and the level...

This diploma thesis is devoted to segmentation of ECG signal based on its quality and compression of quality segments suitable for diagnostics (in telemedicine). A completely new approach is to use accelerometer data to estimate ECG signal quality. This is possible thanks to the Bittium Faros mobile recorder. It records both the ECG signal motion – accelerometric data. A total of 34 features were extracted from accelerometric data. Using these features the predictive model was taught to classify the ECG signal into 3 quality groups according to the level of noise. Quality segments were compressed. The wavelet transform in combination with high-frequency bands zeroing and length encoding was used as a compression method.

This master thesis is focused on the diagnostics of vibrations and noise of an internal combustion engine. The work also includes a summary of the current state of knowledge in which the quantities used, transmission paths, measuring devices and the possibilities of performing frequency analysis are analysed. As part of the technical experiment on which this work is based, vibrations and noise on the tractor engine are measured. The obtained data are then further processed using the BK Connect program. Subsequently, a frequency analysis is performed, specifically an order analysis. The conclusion of the analysis consists of an evaluation of individual orders that cause excitation that occur in the investigated motor.

The main aim of this thesis is to design and build automatic calibration system for inertial measurement sensors. The calibration system is intended to support the development of devices with inertial measurement sensors. The great emphasis is placed on the configurability of system and for this reason all calculations are realized by Matlab system, which is well known by engineers. There is also presented design of inertial measurement unit, which is used as a~model sensor unit for calibration system development.
