Influence of muscle imbalances on the pelvic position in karate trainees
Buchtelová, Eva ; Pavlů, Dagmar (advisor) ; Fojtík, Ivan (referee) ; Šorfová, Monika (referee)
Title: Influence of muscle imbalances on the pelvic position in karate trainees Aim: : The aim of this thesis is to contribute to the solution surrounding the problematic of the position of the pelvis. Also to compare the difference between the positions developed by the influence of muscle imbalances in a group of children aged from 11 - 13 years in sports clubs specializing in karate together with children from 5th - 6th grades in primary schools in the Ústí nad Labem district, children who do sports just for fun and occasionally. Methods: : The main method of this empirical research was that of measuring the somatometric characteristics and the body composition (%BF) in children of middle school age, the method of examination by manual medicinal techniques for discovering the pelvic positions and the lumbar lordosis (Lewit, 2003) and the method of carrying out the diagnosis of the stabilisation function of abdominal muscles according to Kolář (2009) - the diaphragm test, the test of body flexion and the test of intraabdominal pressure. Another applied method was the 3D analysis of the movement for determining the range of the pelvic movement from maximal retroversion up to maximal anteversion. The movement of the pelvis in relation to the laboratory and the lumbar spine in relation to the pelvis...

Kinesiological analysis of upper limb punch strike in sports karate
Pavelka, Radim ; Kračmar, Bronislav (advisor) ; Fojtík, Ivan (referee) ; Pánek, David (referee)
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
