Effect of water temperature on the electrical activity of muscle
Novotná, Petra ; Pánek, David (advisor) ; Jalovcová, Miroslava (referee)
Title: Effect of water temperature on the electrical activity of muscle Objective: Main objective of this work is to determine the spatiotemporal changes in muscle activation depending on different properties of the environment. All this at a defined muscle power output. Measured by hand dynamometer. Methods: This is a case study. Is processed and analyzed the relationship of the forearm muscles against the aquatic environment (different temperatures - 15 řC, 24 řC and 35 řC) and against dry. Muscular power output is defined and measured by hand dynamometer. Muscular power output was determined as isometric contraction flexors of wrist and fingers of dominant hand. It all in three different modes. The research group were included 5 healthy individuals (3 women, 2 men). As objectivization method was determined surface electromyography. Findings: There is no influence of water temperature (15 řC, 24 řC and 35 řC) on spatiotemporal activation of muscle. It all at a defined muscle power output. There is also no changes on spatiotemporal activation of muscle in aquatic and dry. Keywords: muscle contraction, temperature, water environment, surface electromyography, Water Surface EMG

Kinesiolgy analysis of function selected muscles of upper limb after brest augmentation
Víšková, Anna ; Kračmar, Bronislav (advisor) ; Véle, František (referee)
Title: Kinesiologic analysis of function of selected upper limb muscles after female breast augmentation Objectives: The aim of this research is to analyze the functionality and scope of involvement of the injured muscles due to plastic surgical augmentation procedure at pre-selected physical activities before and after surgery a few months later (specifically, three months - the time the patient left the recovery) using a noninvasive surface electromyography (EMG). Methods: A Case Study measuring method of noninvasive surface electromyography in combination with the method of temporal phase shifts involved in the activation of muscle movement, accompanied by a support method of integrated EMG. Results: There differences have been observed in the timing of individual muscles measured during performing selected testing exercises before and after completion of the augmentation plastic surgery operatios. Furthermore, the possibility of the loss of muscle strength has been detected by some measured muscles and this has the potential to take over functions of damaged muscles. Key words: plastic surgery, female breast augmentation, surface electromyography, upper limb muscles, musculus pectoralis major

Evaluation of EMG Activity of the Shoulder Girdle Muscles during Exercises with Thera-Band in Aquatic Environment and on Land
Holländerová, Dita ; Pavlů, Dagmar (advisor) ; Pánek, David (referee)
Title: Evaluation of EMG Activity of the Shoulder Girdle Muscles during Exercises with Thera-Band in Aquatic Environment and on Land. Objective: The main goal of this thesis is to determine a degree of muscle activity of upper trapezius muscle and other selected muscles in the aquatic environment and on land and to compare the values. Furthermore, to determine whether the upper trapezius muscle activates in the aquatic environment later than on land, compared to other selected muscles. Methods: This is the case of study, where the degree of muscle activity and the onset of activation of the upper trapezius muscle and other selected muscle is analyzed and then evaluated during shoulder abduction in two different environments using elastic resistance strength (yellow Thera-Band). As an objectification method surface electromyography had been chosen. To ensure the same set of initial conditions the abduction was performed in sitting position. The same chair was used in water and on land. Four female participants part in the experiment. Findings: The degree of muscle activity of upper trapezius muscle in the aquatic environment significantly decreased. It wasn't confirmed, that the upper trapezius muscle has been activated later in water than on land. Timing of selected muscles in aquatic environment...

Use surface electromyography in the clinical practice
Dobisová, Anna ; Crhonková, Radka (advisor) ; Demeková, Júlia (referee)
Surface electromyography is a non-invasive method of examination. Surface electrodes localized on the skin above the muscle record action potentials of particular muscles' motor units. Acquired EMG recordings enable to assess muscle activity, muscle fatigue or recruitment of particular muscles during the motion (timing) and muscle coordination. Modern EMG devices are compatible with a scale of sensors that record other biosignals and are able to synchronize them with EMG records. That's why SEMG is applied in neurology, physiotherapy, ergonomics, biomechanics, orthopaedics, prosthetics, sport and in other spheres. As a non-invasive method it has its advantages, but of course its limits as well. Powered by TCPDF (www.tcpdf.org)

The comparative kineziologic analysis of forward stroke on wheelchair and crawling
Vatěrová, Hana ; Kračmar, Bronislav (advisor) ; Suchanová, Klára (referee)
Title: The comparative kineziologic analysis of forward stroke on wheelchair and crawling. Objectives of the Thesis: The aim of the thesis is to compare muscle activity of selected muscles in shoulder girdle during forward stroke on wheelchair and crawling. Method: Surface electromyography combinated with kinematography analysis used synchronized video recording. Results and Conclusions: As the research shows, there is a difference in muscle activity (timing) between forward stroke on wheelchair and during crawling. It was proved that the activity of forward stroke on wheelchair does not have natural locomotive character. Keywords: Forward stroke on wheelchair, crawling, shoulder girdle, surface electromyography, kinematics analysis.
