Gait analysis using EMG signals
Korčáková, Ivona ; Janoušek, Oto (referee) ; Koťová, Markéta (advisor)
This bachelors thesis is focused on the analysis of gait using EMG signals. It includes the physiology of a muscular system, with a focus on the lower limb. Bipedal walking consist of ste system that are described and explained also with the movements of the joints. Another chapter is dedicated of Electromyography and this application to the walk analysis. This thesis also includes designing a custom program enabling dataprocessing. Thi final chapter focuses od the data processing. The final chapter focuses on the data analysis and its evaluation.

Comparison of activation of the selected muscles during snowboarding on simulator and snow
Kubišta, Adam ; Gnad, Tomáš (advisor) ; Bačáková, Radka (referee)
Title: Comparison of activation the selected muscles during snowboarding on simulator and snow. Author: Bc. Adam Kubišta Supervisor: PaedDr. Tomáš Gnad Objective: This study aims to compare activation of selected muscles during basic skidded turn on snowboard on simulator and snow. Methods: Muscle activity was measured by a method called surface electromyography. The activation of selected muscles was examined using a comparative analysis. The timing of the participation of selected muscles during the basic skidded turn on snowboard on the Maxxtracks simulator and on the snow was compared. Results: This research with this method did not show a significant similarity in snowboarding on the Maxxtracks simulator and on the snow. The results of our work show the difference in timing of lower limb muscle participation on a snowboard during the basic skidded turn on the Maxxtracks simulator and on the snow. Each participant experienced a different participation of the observed muscles in the step cycle and no obvious movement pattern was discovered. Key words: Snowboarding, electromyography (EMG), muscle activation, simulator

Monitoring of changes regarding muscle involvement in specific areas of human motion system when walking and nordic walking
Škopek, Martin ; Kračmar, Bronislav (advisor) ; Kučera, Miroslav (referee) ; Jandová, Soňa (referee)
The Dissertation is concerned with monitoring of changes regarding muscle involvement in specific areas of human motion system when walking and Nordic walking (NW) with focus on adults and by means of electromyography method. Within the process of field testing there were 9 randomly selected individuals at the age of 50 - 60 tested to elicit differences in the motion system. There was an effort to find certain differences within involvement of specific muscle groups in the area of shoulder girdle, pelvic girdle and lower limbs and retrieval of similarities of coordination attributes concerning locomotion at horizontal presented by paradigm of kinesiological content of reflexive crawling according to Vojta's principle. Kinematic analyses was used to discover a difference in involvement of specific muscles between Nordic (v = 5 kph) and regular walking (v = 4, 75 kph) up to 10˚ of ascent. Muscles where their MVC was diagnosed the difference in individual muscle involvement was monitored expressed in percentage. The values found were consequently related to their referential value of MVC and tested by means of Wilcoxon test for dependent selection. Muscles where MVC value was not diagnosed the intraindividual comparative analyses of activation muscle pair similarity was carried out on the grounds of...

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

Description quadrupedal locomotion diagonal pattern in specific sport activity (rope climbing, walking, pull-up)
Bačáková, Radka ; Kračmar, Bronislav (advisor) ; Kučera, Miroslav (referee) ; Zounková, Irena (referee)
Tittle: Description quadrupedal locomotion diagonal pattern in specific sport activity (rope climbing, walking, pull-up) Aim of work: The aim is to find a description kvadrupedal locomotion diagonal pattern with rope climbing and its motion pattern compared with the motion pattern of walking and pull-up. Methods: This work is descriptively-association study with quantitative and qualitative analysis. The dates were measured by surface electromyography and 2-D video-analysis. Results: Alternating activation of upper extremities (rope climbing without the lower extremities), we proved that the movement supporting lower extremities is quadruped locomotion diagonal pattern. Symmetric work of upper extremities (pull-up) is not in response at lower extremities quadruped locomotion diagonal pattern. Key words: Electromyography (EMG), quadruped, diagonal pattern, rope climbing, pull-up, walking
