INTRODUCTION: Cardiovascular drift is a phenomenon, which appears after 10 - 20 minutes of prolonged moderate - intensity exercise (50 - 75% VO2max). CVD appears in a neutral or hot environment. It is characterized by a decline in stroke volume and systemic mean arterial pressures and a parallel increase in heart rate. Cardiac output is maintained nearly constant. The theory of CVD shows increase of core temperature and sympathetic nervous system as cause of increase of heart rate. GOALS: The goal of this thesis was find out the change of heart rate depending on time. Then we found out changes of oral, tympanic, axillary, vaginal and superficial skin temperature. We found out correlation between vaginal temperature and heart rate and then between skin temperature and vaginal temperature. METHODS: Blood pressure, heart rate, oral, tympanic, axillary, vaginal and superficial skin temperature were measured during 60 minutes of cycling (intensity 55% VO2max; 1,99 ± 0,14 W/kg). It was measured at 13 women (25,5 ± 1,3 years; 69,1 ± 7,7 kg). RESULTS and CONCLUSION: There was statistically significant increase of heart rate compared to value from 10. minute. during. There was increase of tympanic temperature compared to value from 10. minute only at the end of exercise. There was significant increase of vaginal and...

Title: Electromyographic Analysis of the Different Handlebars Grips Effect on the Shoulder Blade Fixators Aims: The main objective of this thesis is to carry out a methodological study on the impact of different handlebars grips on the shoulder blades fixators. Result of the grip change is not only reduction of the upper fixators activity and the increase in the lower fixators activity but also co-contraction index increase and muscle fatigue reduction. Based on the hypothesis we assumed that the highest activity rate of the lower blades fixators and the lowest activity rate of the upper blades fixators will be during the handlebars brakes grip. The highest co- contraction index will occur during the handlebar brakes grip and the maximum muscular fatigue will occur during the grip at the top of the handlebars. The first part of the thesis is focused on the literature search and facts retrieval pertaining to the studied issue. In the second special part of the thesis we conducted a research during which the muscle activity of the upper and lower blade fixators was recorded. Three different handlebars grips were considered during the measurement using the cycle ergometer. Methods: Muscle activity was scanned and recorded using surface EMG. Maximal voluntary contraction of selected muscles based on...

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.

This diploma thesis is focused on the observation of influence of Vojta's reflex locomotion on the activity of shoulder girdle's muscles at patients with the subacromial impingement syndrome. We examined ten patients with the subacromial impingement syndrome as well as twenty asymptomatic individuals. We evaluated the impact of just one Vojta's reflex locomotion therapy on the activity of muscles using the Method of the Surface Electromyography. At the same time we evaluated if the reaction on the therapy had some impact on measured values. The therapy always took at least time necessary to obtain any reaction of each of the individuals, although the maximum limit of the therapy was 32 minutes. The impact of Vojta's reflex locomotion therapy had not statistical importance with regard on changes of muscle activity after and before the therapy, with regard on the symmetry of muscle activity, as well as the difference of beginning of activation of every muscle before and after the therapy. The statistical importance was influenced just by the corporeal disposition of every measured individual, which was observed on the timing. The influence of the corporeal disposition on the average measured values with regard of the left - right side symmetry has no statistical importance. The statistical...

Title: Comparison of rhythmic stabilization according to Kabat with the techniques used in practice. Objectives: The main aim of this thesis was to measure and compare the level of muscle activity and the level of cocontraction of Muscle quadratus lumborum sinister, obliquus internus abdominis sinister, rectus abdominis sinister and dexter obliquus externus abdominis, which were exposed to different stabilization techniques - rhythmic stabilization and technique used in practice - technique "shove". Methods: This is an experimental study which is analyzed and then assessing the level of cocontraction of antagonists and the degree of muscle strength in two different ways- the technique of PNF and technique pushing. We use a surface electromyography as an objectification method. The sample consisted of 7 probands. Results: It was discovered that left side lying position not enlarged to the level of activity of all muscles required, therefore the muscles involved in PNF diagonals. Prerequisite increased level of activation during rhythmic stabilization technique according to Kabat was confirmed only in m. quadratus lumborum sinister and m. obliquus externus abdominis dexter and the values statistically insignificant. Participation of the rectus abdominis though its dominant and statistically...

Title: Consequences of forced hypokinesia on human movement aparatus. Objectives: The aim of this study was to find out the influence of forced hypokinesia after total hip replacement on the excitability of α motoneurons. I deal with the changes of H-reflex and M-wave latencies and the changes of the recruitment curves. The results of the operated and non-operated (kontrol) lower limb were compared. Methods: Five volunteers 3 - 4 weeks after total hip replacement participated in this study. The age was 62,4 (± 3,01). The H-reflex was elicited by stimulation of tibial nerve in a poplitel fossa. The H-reflex and M-wave latencies and its recruitment curves were obtained. After that the values of the operated lower limb were compared with the non-operated one (control). The results were evaluated as case studies. The EMG device Grass Telefactor was used to detect the electrical potential of soleus muscle. The rectangular pulses of 0,5 ms duration were used for stimulation tibial nerve by Grass 88 Stimulator. Then the data were transduced by CED Power 1401 device. Results: We found out that the H-reflexes of both lower limbs were not elicited in the case study no. 2 and the H-reflex of a control lower limb was not elicited in case study no. 1. The stimulus intensities for eliciting H-reflex and M-wave...

The Master's thesis is focused on monitoring of the core muscles and m. biceps femoris activity in postural stability examination by Dynamic Neuromuscular Stabilization tests using surface electromyography in patients with LBP. Trunk extension test, trunk flexion test and squat test were chosen. The aim of this study was comparing muscle activity timing, symmetry of muscle activation and average activation between healthy subjects and patients with LBP. The changes of muscle activation pattern were observed and average activation was determined. In theoretical part the principles of DNS, surface electromyography and the relationship between postural stabilization and LBP are discussed. Two groups were measured - patients with LBP and a control group, 20 subjects together. The onset times were measured and rank of activation for each test and for each subject was determined. Then the average order for whole group was specified. Measured data were evaluated according to Wilcoxon signed-rank test. In average activation there was analysed change of activation in time. Results were compared between two measured groups. There is significant difference between the two groups in the rank of activation of m. ES l. dx. in trunk extension test and m. EO in squat test. Assymetry in timing of the right and left...
