Use of regeneration in young soccer players and subjective perception of the regeneration effect
Cháb, Jan ; Majorová, Simona (advisor) ; Hošková, Blanka (referee)
Title of bachelor's thesis: Use of regeneration in young soccer players and subjective perception of the regeneration effect Goals: The main objective of the bachelor's thesis is to use a survey to find out what role regeneration plays in young football players and how they subjectively perceive the effect of regeneration. The secondary goal of the bachelor's thesis is to create a recommendation for the effective use of regeneration in the training process of young football players based on materials from professional literature and studies, supplemented by my experience in regeneration in football. Method: This is a theoretical-empirical work using quantitative research, where the data was obtained through a survey. A total of 45 respondents from youth football clubs AC Sparta Prague, FK Motorlet Prague and FK Jinočany took part in the survey. The participants received the survey in printed form. The survey contained a total of 21 questions. Only answers to questions and age were given. These were closed and open questions that served me to answer the main goal of my bachelor's thesis. Data collection took place in May 2024. Results: It is evident from the results that most of the interviewed players attach due importance to regeneration. According to the results of the survey, the most players,...

Using regeneration procedurs in football by young and elite players
Pavlů, Adam ; Hráský, Pavel (advisor) ; Majorová, Simona (referee)
Author: Adam Pavlů Title: Using regeneration procedures in football by young and elite players Objectives: The main objective of this bachelor's thesis is to find out the use of individual regeneration procedures in active players in the adolescent and male categories. Next, find out how individual regeneration procedures affect the psychological and physical side of each player, how it makes them feel and how it affects their sports performance. Methods: The thesis is processed in the form of a systematic research. Domestic and foreign literary resources and scholarly foreign articles were used to process the theoretical part. I obtained the material basis for the processing of the practical part through the questionnairy survey. Results: The final use of regeneration procedures within this club is not very favourable. Less than three quarters of players (68,2 %) do not have the option of using any regeneration procedure. In terms of individual regeneration, exactly half of the players (50 %) do not use sports massage for recovery. The same statistics were shown for sauna regeneration. More than half of the players (54,5 %) also do not use whirlpool baths, hardening or other regeneration procedures. Conversely, most players had abundant representation of regeneration through movement. Most players...

What hinders the recovery of zooplankton communities in acidified lakes?
Jůzek, Václav ; Sacherová, Veronika (advisor) ; Kaňa, Jiří (referee)
Acidification of soil and water environments, which emerged with the beginning of the Industrial Revolution, became a major ecological problem of the 20th century. The increase in emissions and subsequent deposition of acidifying substances into the environment has caused a significant decline in abundance and biodiversity of aquatic organisms in European and North American lakes. Emissions causing acidification have been reduced since the 1990s, yet aquatic ecosystems are not returning to their pre-acidification state. This thesis concludes the factors affecting the course of chemical and biological recovery of aquatic ecosystems affected by atmospheric acidification. The reviewed literature shows that communities newly established in acidified waters seek a new ecological equilibrium, and thus recolonization of native species is not limited by merely unsuitable water chemistry itself. Bohemian forest lakes have also been affected by acidification and are now in the process of recovering. The main factors affecting the recovery of natural zooplankton communities in lakes are high aluminium concentrations, periodic pH fluctuations, catchment characteristics and, more recently, climate change and associated bark beetle-induced tree dieback. Keywords: acidification, recovery, zooplankton, Bohemian...

Recovery and recrystallization of austenitic steel 08Cr18Ni10T
Čech, Jan ; Gregor, Martin (referee) ; Foret, Rudolf (advisor)
This thesis deals with influences of graded deformations, temperatures and holding times on the grains and subgrains size in steel 08Cr18Ni10T. In literary part of the thesis there are described static and dynamic annealing treatments, then also austenitic stainless steels and some selected types of their processing. In experimental part there is studied grain size on differently deformed samples annealed in temperature range 1050–1200 °C for 10, 50 and 100 minutes. Analysis of present structures units was perform by EBSD. Except of that, there were realized chemical analysis of selected inclusions and also hardness test were realised. Achieved measurement shown, that grain size of chosen steel is depended on all 3 variable values.

Recrystallization study of free-cutting steel by in-situ SEM/EBSD technique
Babinský, Tomáš ; Němec, Karel (referee) ; Petrenec, Martin (advisor)
Placing recrystallization annealing in a manufacturing proces is often necessary in order to restore plasticity of worked blanks right before working products to its final shape. For better understanding of processes which are taking place in a material during annealing the use of in-situ techniques is favorable. Such observations enable us to watch changes in the materiál in real time at the original spot. Observations at grain-level are ideally made with scanning electron microscope – SEM by electron back-scattered diffraction – EBSD. The technique makes watching nucleation, growth and potential coarsening of recrystallized grains possible. Special construction of a tensile stage allows us to watch changes of a sample during tensile tests which can be used in observing influence of MnS inclusions on plasticity of free-cutting steels. Materials studied in this work are commonly used free-cutting steel 11SMnPb30 and its lead-free alternative 11SMnBi30.

Anorexia nervosa - recovery
Chudačíková, Dominika ; Presslerová, Pavla (referee)
The rigorous thesis deals with anorexia nervosa as one of the basic forms of eating disorders, with emphasis on the very common chronic progression of this serious psychiatric illness. This thesis is based on the scientific fact, that conspicuous eating habits, constant control of thinking and behavior, as well as self-perception disorders, are observed in most cases, even in already cured patients. Risk factors such a long-term stress or prone personality, can result in the acute phase of anorexia nervosa. The rigorous thesis is qualitatively focused. The chosen methods of data collection are a questionnaire survey and a following semi-structured interview. The condition for participation in the research is the past experience with anorexia nervosa, without the current presence of the acute phase of this disease. The main goal of the rigorous thesis is to take a look, through specific stories of interviewed respondents, on individual ways of the recovery from the acute phase of anorexia nervosa, to map their current feelings, needs and burning issues. Based on the survey results, the outcome of the rigorous thesis are the specific recommendations for individuals who are prone to the emergence of recurrence of anorexia nervosa. These recommendations should lower the risk of relapse of the acute...

Ways of recovery in the context of Recovery approach
PETRŽÍLKOVÁ, Hana
The point of my final work is to introduce a social worker in multidisciplinary team, who works on the fundamental of Recovery way, like a way which is aimed on the picking responsibility of the client and his/her decision. Then to look for the client´s meaningful life and what part in this process is the part of social worker.The work is divided into four chapters, which try to introduce the mental disease and its difficulty. Next chapters are more aimed in Recovery attitude. Then there is used a CARe method, which comes from the Recovery way and how a social worker works with it. It shows his/her role in the multidisciplinary team, whis is using Recovery way, and how they work with people with mental disease. Finally I use the casuistry and particular ways of clients and the work of social worker, who works with the instruments that support the way back to recovery.

The Verification of the Use of the Heart Rate Variability in the Management of Training Process in Adolescent Mountain Bikers
KADLEC, Jakub
Cross-country Olympic (XCO) is one of the endurance sports. The training process of mountain bikers is very demanding because the rider must be complex in endurance and anaerobic skills. Alfa and omega of the training process is a periodization of training load and recovery. Heart rate variability (HRV) can help us assess body's condition and readiness for training. In the practical part of the work, an experiment was carried out, which was attended by eight adolescent mountain bikers. The intervention took place during the training camp. The total intervention time was four weeks. The participants were randomized into two groups. The first experimental group (ES) (n = 4) was a graduated training camp with a heart rate variability guided training load. The second group was a control group that used a classical predefined training plan. For evaluation of HRV training efficiency a VO2max test and 20 minutes time trial (20TT) on an ergometer were used. The results showed an improvement in mean power output during 20TT in the experimental group (PRE 303.5 W; POST 317.5 W) and relative values (PRE 4.58 W.kg-1; POST 4.68 W.kg-1). On the other hand, there were no changes in average power (PRE 308 W; POST 305.7 W) and relative values (PRE 4.20 W.kg-1; POST 4.20 W.kg-1). From a statistical point of view, there was no effect of HRV training on performance indicators (p <0.05). Our experiment failed to confirm the usefulness of HRV training for cyclists.
