Sukovič, Richard ; Brtník, Tomáš (advisor) ; Šafránek, Jiří (referee)
VLIV VZTAHU DÉLKY DOLNÍ KONČETINY A VELIKOSTI RÁFKU NA PSYCHOFZIOLOGICKOU ODEZVU ORGANISMU Cíle: Cílem této práce je posoudit vliv délky dolní končetiny (DK) na psychofyziologickou odezvu organismu při jízdě na horském kole s odlišnými velikostmi ráfků. Metody: Soubor probandů tvořilo 20 mužů ve věku 26,4 ± 4,2 let. Jednalo se o experiment. Psychofyziologická odezva byla stanovena na základě výkonu (zajetého času), tepové frekvence a subjektivním hodnocení jízdních vlastností horského kola a vlastního vynaloženého úsilí hodnoceného na Borgově škále. Ke kontrolní analýze při testování byl použit přístroj MetaMax 3B. Testovány byly tři velikosti ráfků o stejné šíři plášťů. Jízdy byly realizovány na 800 m dlouhém okruhu. Testované osoby absolvovali každou jízdu s individuálně zvoleným fixním převodem v poloze v sedle s maximálním možným úsilím. Výsledky: Při jízdě na různě velkých ráfcích jsme u skupiny č. 2 (85 -90 cm DK) shledali velký rozdíl (P = 0,016) v dosažených časech při jízdě na různě velkých ráfcích. U skupiny č. 1 jsme shledali významné rozdíly v průměrné tepové frekvenci (P = 0,010), který činil 3 tepy a u subjektivního hodnocení vlastního vynaloženého úsilí pomocí Borgovy škály jsme se pohybovali na hranici významnosti (P = 0,060). Skupina č. 3 (97 - 101 cm DK) se pohybovala na hranici...

Title: Attitudes of UK FTVS students to summer camps for children Objectives: The main aim of this work is to find out what was benefit of children 's camps for UK FTVS students and what they are currently attitude. Methods: The research was divided into two parts. In part A I used the method of questioning followed by analysis. In testing were 175 participants. I interviewed students of the Charles University FTVS and it took period from June 2018 to July 2019. The data were subsequently evaluated using classical statistical methods and interpreted by graphs and frequency tables. Part B conducted semi-structured interviews with 9 probands who were selected as a representative sample based on Part A interviews. The data were evaluated by basic statistical methods, exactly by using the frequency table and Likert's scaling method to determine the level of attitudes among respondents. Results: In part A we find out that only 7% of the individuals in the sample had never participated in a children's summer camp. It was also found that fourteen respondents of the whole sample had a negative attitude to the camps, equivalent is 8%. Participants of one or two camps reported a negative attitude in 28% (ten of twenty six). In the second group, three to six camps, it was 5% of cases (three of fifty three)....

Schuran, Michal ; Šafránek, Jiří (advisor) ; Brtník, Tomáš (referee)
Title of the study: Cycling - The use of power meters in a race Study aim: The aim of this study is to prove power meters usability during races which are full of variable conditions and to find out in which situations it is suitable or unsuitable to follow this data. Methods: This study is based on quantitative research. We used a questionnaire with open-ended questions. Results: The study confirmed the usability of power meters during races. Power meters are used especially after post-race analysis (92 %). 79 % of all respondents use it for the informative purpose during the race and 67 % ride the race according to the data given by power meters. Power meters are mainly used in time-trials or longer performace, such as climbing or breakaway. The results has shown a significant difference between amateurs and professional cyclists. 83 % of amateurs stated that they often ride according to their critical values when riding more than 15 minutes whereas professionals regularly ride beyond their critical values. Conclusions: Cyclists using power meters while practicing use them also during the races. Amateurs use them especially during races because of more frequent solo ride. Getting data from this questionnaire by World Tour riders would be very interesting as we would be able to compare the results...

3 Abstract Title: Quality of water and water touring on selected West Bohemia rivers Aim: The main aim of the thesis was to find out if there are changes of water quality in the most significant West Bohemia rivers as a result of the changing approach to our environment in the past several years. Furthermore, to consider whether the water quality has changed in relation to finished water management projects and whether this change influenced using rivers for water touring. The observed rivers: Úhlava, Úslava, Radbuza, Mže, Berounka and Střela. Methods: The first part of the thesis, discussing the water quality, analyzes available data collected from written and electronic resources and discussions with experts. The gained material mostly within the last 10 years was organized, compared and summarized. The second part brings the evaluation by canoeists who regularly canoe down these rivers and can visually judge the water quality. This information was interpreted from semi- structured interviews with canoeists. Results: Our presumption that the water quality on the selected West Bohemia rivers is improving was proved, which is one of basic conditions for water touring as well.

Title: Comparison of Current Methods of Cycling Set Up for Cycling Olympic triathlon (case study). Objectives:. The main aim of the thesis is to compare the subjective and objective performance of selected fitting settings. Methods: : In our work we compared three methods of cycling setting - theoretical methodology of calculation and individual dynamic methodology of Retül and Guru Fit Bike. We used the objective performance evaluation Spiroergometric stress test. We have rated the performance achieved at the level of aerobic and anaerobic threshold and then compared the maximum achieved parameters. The pedal technique was evaluated using the Wattbike SW. Comparison was performed using percentage points. Subjective assessment was carried out by means of a controlled interview. Results : We found that proband in the subjective evaluation better evaluated the methods of the Guru Fit Bike and Retül compared to the objective rating in which the theoretical method achieved the best results. Keywords: biomechanics, fitting, effectiveness of cycling, pedal technique, spiroergometry.
