Incidence of injuries and their prevention in women's and men's futsal in the Czech Republic
Kabourková, Denisa ; Pravečková, Petra (advisor) ; Kočíb, Tomáš (referee)
Title: Incidence and Prevention of Injuries in Men's and Women's Futsal in the Czech Republic. Objectives: The aim of this study was to map the frequency of injuries among players in the First Futsal League for both men and women in the Czech Republic. To identify the most common types of injuries in this sport, the situations in which injuries occur, the length of recovery periods, and how players try to prevent these injuries. Methods: For the research, a non-standardized questionnaire with both closed and open-ended questions was created on survio.com. The questionnaire was sent electronically to 12 clubs in the First Futsal League for men and women. A total of 121 questionnaires were completed. Data processing was aquired by using Microsoft Excel. Results: The results showed that for both genders, the lower extremities were the most injured body parts (men 63.2%, women 71.4%). The ankle joint was the most frequently injured (40.7% men, 38.8% women), followed by thigh muscle injuries in men (37.0%) and bruises in women (31.3%). Thigh injuries were the third most common for women (26.9%). The most common cause of injury among respondents was an unintended fall caused by an opponent or due to failure of movement control (men 41.7%, women 43.6%). The duration of treatment was also similar for both...

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...

Password Recovery of RAR, BZIP, and GZIP Archives Using GPU
Mikuš, Dávid ; Holkovič, Martin (referee) ; Hranický, Radek (advisor)
This thesis describes cryptographic protection and the implementation of file password of RAR, GZIP, BZIP formats. For password recovery multi platform Wrathion tool is used, the tool can obtain a password from an encrypted file by using its modules and password generators. The module provides parsing of input file and storing data, which are later used for password validation. To accelerate calculations, graphics card and OpenCL framework is used. The core of thesis is the implementation of Wrathion's modules for password recovery of the formats denoted above and measuring the speed and comparision with competeting tools.

Light Induced Degradation of Solar Cells
Indra, Jiří ; Solčanský, Marek (referee) ; Vaněk, Jiří (advisor)
This master’s thesis deals with light induced degradation problems. In theoretical section it describes essentials of PN junction function and next light induced degradation mechanisms of solar cells and its symptoms at solar cell operation. In practical section it deals with set of measurements of solar cells since production of the silicon wafer to the complete solar cell. Selected cells are submitted to light induced degradation, measured dependencies are then evaluated. Degraded samples are subsequently recovered by two ways at high temperature treatment. The issues are evaluated.
