Bioimpedance signal processing
Soukup, Ladislav ; Kolářová, Jana (referee) ; Provazník, Ivo (advisor)
The aim of this thesis is a study of impedance cardiography and its subsequent use in determining the cardiac output. The calculation in this work uses three default types of biological signals: the ECG signal to gallop and the impedance cardiography. There are identified the necessary parameters of the signals, especially heart rate, heart sounds (S1,S2) and the derivative impedance cardiography. This method of determining cardiac output is non-invasive and is easy to perform for doctor and patient, which is very important for risky patient especialy. Disadvantage is imprecision, that is eliminated by modifying the algorithm of the calculation. User interface for processing all the necessary signals and the subsequent calculation of cardiac output was implemented in MATLAB programming environment and is optimized for data measured and processed in the ISI ASCR.

Physiological response to adventure activity
Řezník, Ondřej ; Psohlavec, Lukáš (advisor) ; Baláš, Jiří (referee)
Objectives: The aim of this study was to investigate the effect of height on the physiological response of the body and walking speed during challenge activity. Methods: The study included 27 subjects, with an average age of 23±2, who were students of the Faculty of Physical Education and Sport (FTVS) at Charles University. The participants walked for 4 minutes over a low obstacle and 4 minutes over a high obstacle at their own pace, followed by 4 minutes over a low obstacle at a specified speed. The monitored parameters were heart rate (HR) and speed (V). Results: The average HR during walking over a low obstacle at the specified speed was 100 beats per minute (σ=12.335), and the average speed was 0.272 (σ=0.221). During walking over a high obstacle, the HR was 133 beats per minute (σ=16.125). During walking over a low obstacle at their own pace, the average HR was 111 beats per minute (σ=13.416), and the average speed was 0.706 (σ=0.269). Conclusion: Walking at height reflects the subjectively perceived risk through physiological responses. The height of the obstacle, which induces a subjectively perceived risk, increases the heart rate by 33 %. The walking speed decreased by an average of 0.434 m/s on the high obstacle. Kewords: adventure education, risk, heart rate, stress.

Analysis of the impact of a 10-day training camp at a higher altitude on performance of adolescent runners
NOVÁK, Daniel
Goal of this Bachelor thesis is to check, if there will be any changes of functional and biochemical parameters of the organism for medium and long length track adolescent runners during a 10-day training camp in high altitude around 1850 meters. Runners were subjected to functional laboratory examination both before and after the camp. All requisites were identical for both the control group and the runners who completed this camp. We were examining measured parameters of VO2max, resting heart rate, breath capacity, expiratory minute ventilation, pulse oxygen, respiratory rate, respiratory exchange ratio, heart rate during peak oxygen consumption and maximum watt performance. Most significant watched parameter was VO2max, where we saw an increase of 15,52 % from original 55,40 +- 7,73 ml-min-1-kg-1 to 64,00 +- 9,87 ml-min-1-kg-1 . Another one was resting heart rate, there was a decrease of 5,86 % for the runners after coming back to lowland compared to rates that were measured before the camp. Erythrocytes values increased by 2,38 %, haemoglobin by 2,69 % and haematocrit by 2,27 %. All these results show factual and statistical importance, the only parameter that didn't show any statistical importance was haematocrit. Result of our research confirmed, that 10-day training camp has a major impact on functional and biochemical parameters of the organism.

Physiological responses on standardized climbing task in sport climbers
Gajdošík, Jan ; Baláš, Jiří (advisor) ; Radvanský, Jiří (referee)
Title: Physiological responses on standardized climbing task in sport climbers Purpose: To determine the effect of height, wall angle, climbing speed and climbing ability on physiological responses in sport climbers. Methods: The study was divided into three parts. 75 sport climbers (36 female and 39 male) completed differing tests on climbing wall and motorized climbing ergometer. Perceived exertion was assessed on a scale suggested by Borg. Indirect calorimetry, venous blood samples and near-infrared spectroscopy were used to assess physiological response, hormonal response and muscle oxygen saturation, respectively. Results: Perceived exertions were higher when climbing to height as opposes to climbing low to the ground on the treadwall (+5,3%; P = 0,013; ηp 2 = 0,149) (Study 1A). The physiological response was higher on the climbing wall as opposed to the treadwall: V̇ O2 (+6%; P = 0,03; ηp 2 = 0,22), SF (+4%; P = 0,04; ηp 2 = 0,20), V̇ E (+9%; P = 0,01; ηp 2 = 0,30) a EC (+16%; P < 0,001; ηp 2 = 0,48). There was an interaction for climbing ability and post- climbing catecholamine concentration (P < 0,01, ηp 2 = 0,28) (Study 1B). With increasing climbing speed greater differences were found for V̇ O2 (P < 0,001, ηp 2 = 0,923) than for StO2 (P < 0,001, ηp 2 = 0,448). Between-subject effect...
