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...

Houdová, Veronika ; Peslová, Eva (advisor) ; Čechovská, Irena (referee)
Title: Influence of buoyancy dumb-bells on load intensity during shallow water aerobic Objectives: The aim of this theses was to compare the heart rate to several variants during 14 minutes head-out aquatic exercise (with simultaneous legs and arms actions and with simultaneous legs and arms actions using buoyancy dumb-bells). 8 females, clinically healthy and with a regular level of physical activity in age between 25-60 years (age 42 ± 11,4 years) were studied. The other aim of this theses was to compare the heart rate during rest on land and rest in water during shallow water aerobic in an upright position with water level to shoulder depth. Methods: We monitored heart rate changes during 14 minutes head-out aquatic exercise by Sport Tester S610i. The results of the tests were analyzed and evaluated with Polar Precision Performance software. Chi-squared test was used to examine the average difference to heart rate during tests. Results: We found non-significant increases on load intensity during test with using buoyancy dumb-bells. Average heart rate during rest in water showed decreases by 13 beats per minute. Keywords: buoyancy dumb-bells, load intensity, heart rate, shallow water aerobic

Title: Innovativ ways to affect overweight and obesity (use of the machine Body - Space VacuTherm). Objectives: The aim of this thesis is to evaluate if walking on Vacutherme encourages and accelerate body fat loss and figure forming as advertisements claim. Based on my own measurements of the clients of our clinic MS Clinic in Slaný I will examine body weight loss, particularly body fat loss, decrease of centimeters of those areas that are exposed to vacuum and change in body composition. I compare the results of clients enrolled in group used to weight reduction only VacuTherm lesson in the machine, with clients of the second group, which combine lessons in the machine with another physical activity attending at least 2 times a week for longer period of time. Methods: To get results important for bachelor thesis I chose only measurement method. For data processing, this method is most accurate. I used two forms of measurement. With one presentation helped me body analyzer Tanita BC-1000, which provided me with information that can not be measured by conventional methods. The second option is a common way of measuring the circumference of lots tracked to within one centimeter. At work I examine a group of 20 women who underwent diagnostic input on physical analyzer, where they were measured value...

Podrazil, Tomáš ; Horčic, Josef (advisor) ; Kovářová, Lenka (referee)
Title: Comparison of the heart rate values and external performance is based on selected field tests determining maximal heart rate in cycling of cyclist and triathletes Objectives: Objective of thesis is to determine the values of maximal heart rate and external performance from selected field tests in cycling and compare them with one another. Methods: Five cyclist were measured in field tests and acquired results were used to create the graphs and tables. Data were obtained by cycling performance meter Powertap and cycle computer Garmin Edge 500. For the analysis of the measured data was used software Garmin Connect. Results: Based on the results of thesis it can be stated, that the measurement turn out as we expected. The difference of maximal heart rate between test-A and test-B is differed by 3-5 beats, which is not decisive. Both tests can be used for determine maximal heart rate. These tests are suitable for measuring the performance of athletes. Maximal heart rate is not in present an important indicator for training of fitness of individual. For training I would suggest to take a test of lactate curve in the laboratory. Keywords: cycling, external performance, heart rate, terrain test, Powertap

Functional load issues in freeskiing
Balla, Dušan ; Gnad, Tomáš (advisor) ; Matošková, Petra (referee)
Title: Functional load issues in freeskiing. Objectives: The aim of this thesis paper is to prove functional load in freeskiing. Methods: Research of available documentations and information. Measurement was done by sport tester divisor followed by analyses of data. Results: Only in ski performance called jibbing the heart rate frequency became stable at 160-180 beats per minute in relation to physical activity. In the activity big-air and half-pipe, the heart beat frequency become stable after load. The biggest fluctuations in heart rate frequency were analyzed in big-air activity done in a pre stage before load. We can attribute this to emotions, adrenalin and conditioned reflexes. In half-pipe activity, the longest follow up phase of heart rate frequency returned to baseline. This shows the greatest intensity of load out of all measured activities. Keywords: freeskiing, functional load, heart rate

Kunčická, Zlata ; Gryc, Tomáš (advisor) ; Bunc, Václav (referee)
Title: The load intensity of golfers during the game Objectives: The aim of this work is to analyze the load intensity of golfers during practice and competition rounds. Methods: The theoretical part was compiled by searching specialized literature. It is a multiple case study, where the load was evaluated on the basis of heart rate, distance, and time using Garmin GPS. The maximum heart rate was determined by laboratory testing and subsequently determined the effort load. Results: Golf in conjunction with walking, which has minimal effects on the musculoskeletal system, could effectively influence the health and fitness. During one round of golf a player walked an average of 10.33 km with an average heart rate 115 beats per minute, corresponding to 59% of maximum heart rate. This intensity develops basic endurance and aerobic capacity. Each round lasted at least 3,5 h and the player burned an average of 1419 kcal.
