Continuous breath monitoring
Sláma, Štěpán ; Sekora, Jiří (referee) ; Kolářová, Jana (advisor)
The purpose of this work is to get informations about the use of biofeedback, the physiology of breath and also about the investigation methods which is the physiology of breath evaluated by. The practical part is focused on creation of an application design with the use of biofeedback and measurement of pilot data. In this part implementation of the application is also done by training of the correct breath wave using biofeedback.

Vliv správného dechového stereotypu na výkon u vytrvalostních běžců
HEJLÍK, Richard
The bachelor thesis provides insight into the issue of breathing stereotype and examines its effect on the performance in endurance runners. The theoretical part of the thesis contains two parts and collects knowledge related to the given issue. The first part focuses on breathing, breathing stereotype, physiology of the respiratory system and breathing control. The second part contains chapters about the history of running, kinesiology of running, running mechanics, running technique and breathing technique during running. The practical part deals with research aimed at improving the breathing stereotype in endurance runners through the intervention of breathing exercises and then determine the change effect of their endurance performance. The research group was consisted of 3 endurance runners aged 19 to 21 years. Their task was to complete training units prepared by me consisting of breathing exercises for 6 to 7 weeks. The evaluation was based on a comparison of the initial and final examination. Initial and final examinations includes kinesiological analysis, spirometric examination, stress spiroergometric examination, Stange´s test and exspiratory apnoeic pause test. The outcome of the research was the detection of positive changes in breathing stereotype in runners. Performance indicators improved in two of the three runners, while ventilation indicators remained without any significant changes. From the results, the effect of changing breathing stereotype on performance in endurance runners cannot be demonstrated. However, it cannot be excluded either. Further research on a larger scale is important to refine the results and identify new findings. It is also necessary to eliminate mistakes and adjust the methodological procedure of the research. If positive results are confirmed, breathing exercises could be incorporated into running training.

Change in breathing economics during exercise due to previous application of breathing exercises based on the Wim Hof method to warm up
MARKO, David
The Wim Hof method is a worldwide phenomenon nowadays. The aim of our work is to determine whether the application of breathing exercises based on WHM will affect the breathing economy in subsequent spiroergometry in adolescent runners (14 boys and 14 girls). Runners underwent two identical graded exercise tests within 3 days, while before one of the tests was performed breathing exercise containing three rounds of controlled hyperventilation and subsequent breath holds. The spiroergometric test consisted of 4 two-minute load phases 1, 2, 3, and 4 W-kg-1. After the application of breathing exercises, there was a significant effect on the kinetics of VO2 (5.09%, 3.11%, 1.55% and 3.39% increase in individual phases of the test). There was also a significant increase of VO2-HR-1 (7.89%, 5.02%, 6.78% and 6.9%). On the other hand, smaller values were measured for the RER, where significance was demonstrated in the first three phases (7.53%, 2.94%, 2.7% and 0.85%). The parameters VE, VT and BF were not significantly affected. No significant differences were measured in the change in the involvement of the breathing sectors. The results of our work show that due to breathing exercises, including controlled hyperventilation and breath holding, the kinetics of oxygen consumption can be accelerated, which can lead to facilitated endurance performance.

Objectice evaluation of postural function of abdominal muscles and intra-abdominal pressure
Novák, Jakub ; Kobesová, Alena (advisor) ; Mezian, Kamal (referee) ; Janoušek, David (referee)
Objective evaluation of postural function of abdominal muscles and intra-abdominal pressure Abstract This dissertation deals with an important mechanism of trunk stabilization, the increase of intra-abdominal pressure. Intra-abdominal pressure is created by the coordinated contraction of the diaphragm, along with the abdominal and pelvic floor muscles. Intra-abdominal pressure works in all directions, stabilizing the trunk while reduceing axillary compression of the spine. Intra-abdominal pressure is increased during activities that require demands on the stabilization of the spine. Intra-abdominal pressure and trunk muscle activity can be measured in several different invasive and non-invasive ways. In rehabilitation medicine, anorectal or gastroesophageal probes are most often used to measure intra-abdominal pressure and measurements are often supplemented by evaluation of muscle activation using electromyography. However, these measurements are costly, time consuming and inconvenient for patients. The most common tool for evaluating trunk stabilization in rehabilitation practice is digital palpation of abdominal wall tension. However, this evaluation method is subjective. Therefore, new pressure sensors have been developed that allow non-invasive assessment of abdominal wall tensionand thus also the...

The effect of the intervention program, breathing exercises on the selected value, and the wind spirometry stereotype
OBRDLÍKOVÁ, Zuzana
This thesis deals with functioning of breathing system, concretely by breathing stereotype and lung's capacities. The aim was to find out if an intervention program of breathing exercises has a positive influence on breathing stereotype and increase of vital capacity and strenuous exhale VC. For stereotype checkup was used muscular dynametr, capacities were measured by spirometry. 34 probands take part in the study, 18 of them were control sample and 16 probands were participated in intervention. They were athlets in the age 15,94 +/- 1,95 years, runner to medium and long distance. Probands undertook an entrance checkup, the intervention program, and when the intervetion was finished, there was an output measurment.
