- Abstract
One of the important issues in internal ballistics is a relation of chamber pressure to projectile velocity. In a gun barrel, the projectile gradually accelerates until it exits the muzzle end. The muzzle velocity can be measured easily but the acceleration phase is quite difficult to observe. In this paper, photonic Doppler velocimeter was used to track projectiles inside gun barrels. The projectiles were accelerated using 4.5 mm calibre CO2 gun and 7.8 mm calibre powder gun. Complete velocity profiles have been obtained for the CO2 gun projectiles. In the case of powder gun tests, only very short profiles showing initial motion of the projectiles were recorded. Problems associated with this kind of measurements are discussed., Jednou z důležitých otázek vnitřní balistiky je vztah tlaku v komoře a rychlosti střely. V hlavni zbraně se střela postupně zrychluje, dokud nevyletí z ústí hlavně. Úsťovou rychlost lze snadno změřit, ale fáze urychlování je poměrně obtížně pozorovatelná. V tomto článku byl ke sledování střel uvnitř hlavně použit fotonický Dopplerův rychloměr. Projektily byly urychlovány pomocí pistole na CO2 ráže 4,5 mm a pušky ráže 7,8 mm. Pro střely z pistole na CO2 byly získány úplné rychlostní profily. V případě testů s puškou využívající prachové náplně byly zaznamenány pouze velmi krátké profily ukazující počáteční pohyb střel. Jsou diskutovány problémy spojené s tímto druhem měření.

Title: Relationship between long-term compensatory exercise intervention and strength- velocity parameters in young football players Objectives: Based on the diagnostic examination, compile a compensation program for the intervened group in order to improve the functional state of the locomotor apparatus and monitor whether this intervention is reflected in the performance in the given motor tests that test the strength-speed abilities of the players Methods: The "20-m linear sprint test" was used to measure linear speed and acceleration, which was measured using time photocells (Witty Timing System). In this test, the average times of all groups were monitored at distances of 5, 10, 20 m. Furthermore, with the help of photocells, a 505 agility test was measured to determine the speed of the players' change of direction. The last test was "Standing broad/long jump" measured by the method (Laser-method measurement SDJ) using a laser optical range finder (Mestek GR20). To determine the normality of the data, the Shapiro-Wilk test was used, the results of which do not reject the normality of the data. For statistical analysis was used paired T-test data between individual measurements in individual groups. MS Excel and Jamovi software were used for recording data and their subsequent analysis....

The work focuses on the evaluation of physical fitness of students, who are 12 and 13 years old. The main aim is to assess the physical fitness of students at general high school and primary school with sports classes. As a part of the thesis, standardized testing will be conducted using the UNIFITTEST (6-60) battery, and two modified tests with their own evaluation tables will be created. The results of the tests will be compared with standardized or modified tables and evaluated according to point standards. The survey will gather data regarding extracurricular physical activity, according to which a trained individual is identified. These individuals will be defined as those who train for at least 3 hours, twice a week. The survey will also collect basic anthropometric data for measuring BMI. All of these aspects were put into context and the results proved, that primary school sports classes achieved better results than general high school children in most tests. By comparing the statistical data, it was proven that although the results are different, the differences are inappreciable at the level of statistical significance.

The purpose of the research part of this thesis is to determine and compare the level of physical abilities of athletes in the hammer throw and discus throw who are enrolled in the Sports Centre for Youth. The testing was conducted in November 2021 and 2022, and a total of 50 athletes in hammer throw and discus throw participated. The test battery consists of several tests that determine the level of speed, explosive strength, as well as endurance skills. The data are compared against the evaluation scale created by the Czech Athletic Association for the purpose of test evaluation. The results were also compared with each other to determine whether hammer throwers or discus throwers or athletes in the youth or junior category achieved a better level of movement abilities. The results of the research show that the vast majority of athletes achieve the average level of ability that was tested. The tests also showed that a relatively large percentage of competitors (around 20 %) from both hammer throwers and discus throwers exhibit a below average level of explosive strength lower limb abilities, which is confirmed to be important for performance in the throwing events, as demonstrated in the next section of the research. In the tests, the male discus throwers achieved a better level, while the result...

The main aim of this thesis is to determine the level of speed and endurance skills in professional female football players of AC Sparta Praha. The sub-objective is to compare the results obtained in the selected fitness tests in terms of the playing position of the players. For the research we have chosen five field tests suitable for the verification of fitness in the field of speed and endurance abilities in male and female football players. These are the 10-meter sprint test, 20-meter sprint test, K-test, BUMAZA test and YoYo Intermittent Recovery Test 1, in addition to the YoYo test, Brower Timing photocells with an accuracy of 0.01 seconds were used for measurement. The test set consisted of 21 female soccer players of the AC Sparta Praha team without the participation of goalkeepers. The testing took place in an indoor hall with artificial grass surface at TCM Strahov. The results showed very good fitness parameters of all players. In the linear speed tests we found out that it is not always a rule that the best results in the 10m sprint are achieved by the same players as in the 20m sprint. We looked in more detail at the comparison of the fitness level of different playing positions. The results of the BUMAZA test, which focuses exclusively on speed endurance, showed that female players at...

Title of the bachelor's thesis: Evalution of speed limits on non elite soccer players Processed by: Jan Havránek Supervisor of the bachelor's thesis: doc. PhDr. Mgr. Aleš Kaplan, MBA, Ph.D. Objectives of the thesis: The aim of this thesis is to monitor and subsequently interpret the results of tests focused on speed abilities in a selected group of non elite football players. Methodology: Testing of speed parameters was conducted on semi-professional football players who play in the ČFL, which is the 3rd Czech league. The evaluation itself was based on the results of six simple tests. These tests included three tests for linear speed: a 5-meter sprint, a 10-meter sprint, and a 20-meter sprint. There were two agility tests: the K-test and the 505 test. And the final test focused on lower limb explosive power: the vertical jump. The results section is then divided into two chapters. The first chapter compares the results of the pre-test and post-test. The second chapter focuses on evaluating speed abilities from the perspective of player positions. Results of the thesis: When comparing the results between the pre-test and post-test, there were no significantly large differences that would allow us to say that there was a development of speed abilities as a result of the testing. From the second part...

The aim of the bachelor thesis is to determine and compare the level of movement abilities of female athletes in artistic and rhytmic gymnastics. It is divided into two parts, namely the theoretical and practical part. The theoretical part deals with a brief description of gymnastics, focusing on artistic and rhytmic gymnastics, giving an overview of their structure and components of sports performance. It includes a definition of all movement abilities and a description of motor tests. In the practical part, the testing method was used, namely the UNIFITTEST (6-60) together with a holistic motor test (Jacík's test) and then statistical methods. The motor abilities of artistic and rhytmic gymnasts aged 8-11 years were tested. The clubs GYMPRA Gymnastická akademie Praha and SK MG Chodov Praha were approached for the measurement. The measured results show that artistic gymnasts have a better level of movement abilities, because they achieved a better level in the three tests than rhytmic gymnasts. For the all-round development of a child, both are equally suitable choices and the choice of artistic or rhytmic gymnastics depends on the individual's preference.

Účelem této studie bylo určit dopad 30minutového zdřímnutí (N30) na běžecký anaerobní sprintový test (RAST) jak během ramadánu, tak po něm. Deset fyzicky aktivních kickboxerů (věk: 21,20 +/- 1,61 let, výška: 174,80 +/- 4,34 cm, tělesná hmotnost: 73,30 +/- 7,10 kg a index tělesné hmotnosti (BMI): 24,00 +/- 2,21 kg/m(2) )) dobrovolně provedlo test RAST po N30 a ve stavu bez spánku (NN) během dvou experimentálních období: posledních deset dnů ramadánu (DR) a podobně jako 3 týdny po ramadánu (AR). Během každého protokolu DR-NN, DR-N30, AR-NN a AR-N30 předváděli kickboxeři výkon RAST. Mezi obdobími ramadánu (DR vs. AR) byl zjištěn statisticky významný rozdíl z hlediska maximálního výkonu (W) (F = 80,93; p(1) < 0,001; eta(2)(p) = 0,89), minimálního výkonu (W ) (F = 49,05; p(1) < 0,001; eta(2)(p) = 0,84), průměrný výkon (W) (F = 83,79; p(1) < 0,001; eta(2)(p) = 0,90 ) a výsledky indexu únavy (%) (F = 11,25; p(1) = 0,008; eta(2)(p) = 0,55). Kromě toho byl faktor zdřímnutí statisticky významný z hlediska maximálního výkonu (W) (F = 81,89; p(2) < 0,001; eta(2)(p) = 0,90), minimálního výkonu (W) (F = 80,37 p(2) < 0,001; eta(2)(p) = 0,89), průměrný výkon (W) (F = 108,41; p(2) < 0,001; eta(2)(p) = 0,92) a index únavy ( % výsledků (F = 16,14; p(2) = 0,003; eta(2)(p) = 0,64). Denní spánek prospívá následnému výkonu v RAST. Výhody zdřímnutí byly větší po příležitosti N30 pro DR a AR. The purpose of this study was to determine the impact of a 30 min nap (N30) on the Running-Based Anaerobic Sprint Test (RAST) both during and after Ramadan. Ten physically active kickboxers (age: 21.20 +/- 1.61 years, height: 174.80 +/- 4.34 cm, body mass: 73.30 +/- 7.10 kg and body mass index (BMI): 24.00 +/- 2.21 kg/m(2)) voluntarily performed the RAST test after an N30 and in a no-nap condition (NN) during two experimental periods: the last ten days of Ramadan (DR) and similar to 3 weeks after Ramadan (AR). During each DR-NN, DR-N30, AR-NN and AR-N30 protocol, kickboxers performed RAST performance. A statistically significant difference was found between Ramadan periods (DR vs. AR) in terms of max power (W) (F = 80.93; p(1) < 0.001; eta(2)(p) = 0.89), minimum power (W) (F = 49.05; p(1) < 0.001; eta(2)(p) = 0.84), average power (W) (F = 83.79; p(1) < 0.001; eta(2)(p) = 0.90) and fatigue index (%) results (F = 11.25; p(1) = 0.008; eta(2)(p) = 0.55). In addition, the nap factor was statistically significant in terms of the max power (W) (F = 81.89; p(2) < 0.001; eta(2)(p) = 0.90), minimum power (W) (F = 80.37; p(2) < 0.001; eta(2)(p) = 0.89), average power (W) (F = 108.41; p(2) < 0.001; eta(2)(p) = 0.92) and fatigue index (%) results (F = 16.14; p(2) = 0.003; eta(2)(p) = 0.64). Taking a daytime nap benefits subsequent performance in RAST. The benefits of napping were greater after an N30 opportunity for DR and AR.

Name: Condition monitorining of elite floorball players Goal: The aim of the work was to assess the fitness readiness of elite flooball players using tests focused on speed and agility. Partial aim of the work was to find out the differences in fitness readiness between female players in different game posts. Method: We used field tests (sprint to 5 m, 10 m, 20 m, 505L, 505P, K - test and BUMAZA) for Brower Timing photocells (Brower Timing® Systems, USA), which has an accuracy of 0.01 s. Tests focused on acceleration speed, locomotor speed, acceleration and motion deceleration capability, agility. The results were processed in Microsoft Excel, the results are expressed through tables. Result: Female floorball players were found to have achieved similar results in their chosen tests as footballers aged 16-17. From older pupils in the categories above, however, both footballers and floorball players had better results. When comparing the different posts in the field tests, we concluded that the players who play at center were the best performers. Key words: speed, endurance, testing, coordination, agility, floorball.

The basic topic of this Bachelor thesis is the introduction of the concept of so-called slow living. The main starting point of this lifestyle is the principle of sustainability and general consideration for other members of society, as well as for the environment and limited natural resources. The concept of Slow defines itself against the accelerating life, the hunger of consumer society, and the unnecessary accumulation of material things that are unnecessary for life. This concept tries to show that a people can be happy with little material things, even more so if their behavior does not contribute to the production of low-quality products, mishandling of the human workforce, and the production of other unnecessary waste. In addition to introduction with the motives for a slow life approach, in the next few chapters we will be focused mainly on the topic of food and clothing, but we will focus on them with a different perspective than we usually look at in these topics. We will be interested in their fast and many criticized variants, and then we will imagine their slower opposites. On many pages we will be dealing with a slow-lifer, which is a model supporter of this approach to life, thanks to which we will be able to imagine better specific situations that a fan of a slower life-style deals with every day. The price and quality of products, as well as the origin of their creation, will also be a big topic in this thesis, because the requirement of fair dealing and transparency of production is characteristic of the slow concept. So we will be accompanied by questions such as - Do I really need this thing? And if so, is it necessary to buy it, or can I get it differently? How much have I been influenced by an commercial that says chosen product meets my criteria and expectations, and is it really so? The following pages will help us answer all of this.

Title: Testing speed and coordination skills in the military environment: a systematic review Objective: Based on a literature search, find out which tests of speed and coordination skills are used in foreign armies. Methods: The presented work is done in the form of a systematic review. Web of Science, Scopus and PubMed databases were selected for searching articles. The search was performed using two search scripts, the first focused on speed and the second on coordination skills. 439 and 297 studies were retrieved from the search scripts and unsystematic searches. These studies were subsequently screened and removed according to the systematic search procedure. After final removal, 33 studies remained for speed and 23 for coordination. Results: The highest representation was found in tests focused on a combination of speed and coordination skills, especially agility tests. Of these, the most used tests are the Illinois Agility Test, the Pro-Agility Test, the 3x5 m shuttle run and the 15 m slalom. The second most represented group is the speed tests, which focus on sprints over various distances. There are 8 different tests in total, with the 20, 30 and 15 m sprints being the most represented. The fewest tests focused on coordination skills. Keywords: army, military, soldiers, cadets, recruits,...

Článek se zabývá ověřením vzorce uvedeného v publikaci Colyna Glynna a Denise P. Wooda s názvem Metody rekonstrukce nehod motocyklů – rychlost podle deformace vozidla a vzdálenosti sunutí motocyklu. Článek byl publikován ve sborníku jako příspěvek XXV. mezinárodní vědecká konference Soudního inženýrství ExFoS 2016. Ověření vychází ze skutečného případu, který posuzoval autor článku. Prezentovaná situace ilustruje, že není možné výsledky výpočtů brát zcela nekriticky a, že každý výsledek by měl být podroben kontrole hrubých chyb.

- Abstract
A constantly increasing number of deaths on roads forces analysts to search for models that predict the driver's propensity for road traffic accidents (RTAs). This paper aims to examine a relationship between the speed and space assessment capabilities of drivers in terms of their association with the occurrence of RTAs. The method used for this purpose is based on the implementation of the interval Type-2 Fuzzy Inference System (T2FIS). The inputs to the first T2FIS relate to the speed assessment capabilities of drivers. These capabilities were measured in the experiment with 178 young drivers, with test speeds of 30, 50, and 70 km/h. The participants assessed the aforementioned speed values from four different observation positions in the driving simulator. On the other hand, the inputs of the second T2FIS are space assessment capabilities. The same group of drivers took two types of space assessment tests-2D and 3D. The third considered T2FIS sublimates of all previously mentioned inputs in one model. The output in all three T2FIS structures is the number of RTAs experienced by a driver. By testing three proposed T2FISs on the empirical data, the result of the research indicates that the space assessment characteristics better explain participation in RTAs compared to the speed assessment capabilities. The results obtained are further confirmed by implementing a multiple regression analysis., Neustále se zvyšující počet úmrtí na silnicích nutí analytiky hledat modely, které předpovídají sklon řidiče k dopravním nehodám (RTA). Tato práce si klade za cíl prozkoumat vztah mezi schopnostmi řidičů vyhodnotit rychlost a prostor z hlediska jejich asociace s výskytem RTA. Metoda použitá pro tento účel je založena na implementaci intervalu Fuzzy Inference System typu 2 (T2FIS). Vstupy do prvního T2FIS se týkají schopností řidičů hodnotit rychlost. Tyto schopnosti byly měřeny v experimentu se 178 mladými řidiči s testovací rychlostí 30, 50 a 70 km / h. Účastníci hodnotili výše uvedené hodnoty rychlosti ze čtyř různých pozic pozorování v simulátoru jízdy. Na druhé straně vstupy druhého T2FIS jsou schopnosti posuzování prostoru. Stejná skupina řidičů absolvovala dva typy testů hodnocení prostoru - 2D a 3D. Třetí považoval T2FIS sublimáty všech dříve zmíněných vstupů v jednom modelu. Výstupem ve všech třech strukturách T2FIS je počet RTA zaznamenaných řidičem. Testováním tří navrhovaných T2FIS na empirických datech výsledek výzkumu naznačuje, že charakteristiky posuzování prostoru lépe vysvětlují účast v RTA ve srovnání se schopnostmi posuzování rychlosti. Získané výsledky jsou dále potvrzeny provedením vícenásobné regresní analýzy.

The aim of this diploma thesis was to measure the physical fitness of pupils from selected elementary school in Hradec Králové. From the obtained results iw was determined whether age has an effect on pupils'performance. Futhermore, the results were compared and on the basis of statistical analysis of the data a comparison of performances of 6th and 9th grade pupils and also comparison of boys and girls. The theoretical part focuses on the topics of a healthy lifestyle, physical activity, physical fitness, physical abilities, physiological and psychological specifics in older school children. The empiric part deals with statistical data processing and their evaluation based on the results in selected physical tests from the test battery called EUROFITTEST. Based on the results and their comparison, I came to the conclusion that in six of the total eight exercises, older pupils achieve statistically significant differences compared to younger pupils. When comparing the average results of 6th and 9th grade pupils, I found that in seven out of eight tests, 9th grade pupils achieve better results than 6th grade pupils. In the end, I found that the boys performed better on average in five tests out of eight. Girls achieve better results on average in one test out of eight. There are no differences in...

Title: Obstacle course racing: the effect of obstacles on the total race time during a Spartan Race Objectives: The aim of this study was to determine the effect of 30-burpee punishment on subsequent running speed (SPD), heart rate (HR) following a missed obstacle, and the final race standings during a OCR race. Methods: In our thesis we used a method of analysis in an official Spartan Race in the Czech Republic. 11 male OCR competitors wore a GPS and HR monitor, from which HR and SPD were measured. Three specific obstacles were chosen where nearly all competitors did burpees (spear throw), half did burpees (traverse wall), and nearly none did burpees (monkey bars). The HR and SPD were measured during the entire race, and specifically noted when the competitors arrived at left the obstacle. Results: The average HR of the entire race was 166.45 ± 3.34 beats per minute. The average time spent at the successful obstacles without burpees was 23 ± 17 seconds, while the average time spent at the unsuccessful obstacles with burpees was 124 ± 11 seconds. The change in HR over the course of successful obstacles was 0.79 ± 3.69 beat per minute, while the change in HR during unsuccessful obstacles with burpees was -3.00 ± 6.70 beat per minute. Total time spent at each obstacle correlated with the final...

Extreme obstacle racing is a brand new sporting industry that is currently developing most not only in Europe but also around the world. I focused mainly on introducing this new sport in order to find out different level of the motor skills of beginners and professionals. In the theoretical part of my work, I defined what is characteristic for this sport and why it is so famous and wanted today. In the practical part, using the proposed test battery, I tested all the motor skills of beginners and professionals in order to identify the real physical differences between them. As a result of these facts, methods of testing, observation, processing, evaluation, analysis and statistics of data, along with the study of professional literature, were used. Based on the established hypotheses, I asked questions that I had in my opinions and attitudes to the beginners and professionals of this thriving sport. Through research and testing, we have found that professionals are certainly more dominant in motor skills than beginners with overall predominance in all underlying motor tests that included speed, endurance, strength and coordination tests. The benefit of this work is the analysis and introduction of a new sporting industry, including the main discovery of real differences between beginners and...

Title: The relationship of explosive strength and CODS performance Objectives: The main aim of this work is to find out the degrese of relatedness indicators between explosively force abilities and performance in individual Agility tests for U16 and U17 footballers Methods: Testing and measurement was performed on a sample of 32 players aged 15-16 from the Bohemians Prague football team. To determine the player's explosive-force abilities, the Kistler board was used in the BEZ laboratory. Agility testing was based on test batteries for this ability (Arrowhead L and P, Illionois, 505 L and R, K-test and Hexagon). The data measurements was processed by using IBM SPSS statistics 22. Results: I have found that the impact of explosive strength abilities was most evident in Arrowhead and Illinois CODS tests at R = 0,4 - 0,7 and p
