Comparison of the effect of the two-mass and hydraulic buffers on the impact of the self-loading rifle
Talanda, Jakub ; Blaťák, Ondřej (referee) ; Vančura, Jan (advisor)
The focus of this thesis are the effects of dual-body and hydraulic recoil buffers on measured recoil of an AR-15 type self-loading rifle. The first part explains the working principles of the rifle and both mentioned buffer designs and points out the sources of the recoil effect. A brief summary of contemporary knowledge and already conducted research into the problem follows. The second part describes an experiment in which the recoil force was measured using a force sensor placed between the rifle butt and shooter’s shoulder. At the end, outcomes of this research are discussed and results obtained for both buffer designs are compared.

Selection criteria for sport shooters
Zrůst, David ; Fiala, Miloš (advisor) ; Hermel, Ivan (referee)
Title: Selection criteria for sport shooters Objectives: The aim of the work will be discovering of the fact, if criteria such as vital capacity of the lungs and apnoea can affect the shooting of air pistol and then mark these criteria as suitable for the selection of talented people. Methods: In this work was used analysis of documents and other professional publications with the possibility of selecting sports talents in sport shooting. Two laboratory measurements were demonstrated, to determine the vital capacity of the lungs by using a personal spirometer and measurement of apnea. At the same time, the probands height and weight were measured. Subsequently, an experiment was proven, in place of probands fired 15 shots from an air pistol according to ISSF rules. Results: The results of the work brought the fact that the vital capacity of the lungs together with apnea do not have a significant effect on the shooting itself in the shooting discipline "air riffle 10m" and is therefore not suitable for use in the eventual selection of individuals for sport shooting. Keywords: selection, sport, shooter, rifle, pistol

The influence of high altitude on shooting efficiency of biathletes.
Boudíková, Adéla ; Dovalil, Josef (advisor) ; Pupiš, Martin (referee) ; Ondráček, Jan (referee)
The main purpose was describe the issue of shooting success rate at high altitude (1 500 - 3 000m a. s. l.). Shooting success rate of elite racers was evaluated using analysation of results from individual races at high altitude in the period 1990/1991 - 2013/2014. High altitude had no statistical effect (p<0,05) on shooting success rate of women and men biathletes in the comparision with lowland but it had more negative effect to women shooting success rate than men shooting success rate. Ten national level biathletes were tested in three tests in lowland, four tests at high altitude and five tests in lowland after the return from high altitude. The test included rest shooting in the prone and standing positions and load shooting in both positions which took part of three kilometers running. Twelve days training camp at high altitude did not improve shooting success rate, shooting velocity and running time in the determinated heart rate. Rest shooting and shooting in the prone position did not change statistically during the whole testing period. At high altitude critical days were registered in load shooting in standing position (6th day, p<0,05) and average running time (9th day, p<0,05). Rifle manipulation and shooting are automate motions which are not influenced by high altitude. Most...

The influence of optoeletronic gunsight on shooting accuracy and precision
Bílek, Zdeněk ; Fiala, Miloš (advisor) ; Brych, Jan (referee)
Title: The influence of optoeletronic gunsight on shooting accuracy and precision Objectives: The primary aim of this diploma thesis is to statistically appraise the influence of optoelectronic gunsight on shootihg accuracy and precision. The sighting device was mounted on Heckler & Koch MP5 machine gun during both static and dynamic shooting practices. Methods: Shooting targets evaluation was based on the numerical method of detecting the mean point of impact. Statistical data processing was based on the method of comparison of means. To determine statistical significance we used dispersion analysis by means od ANOVA program. Results: We ascertained that the employment of optoelectronic gunsight has a statisticaly significant effect on static shootig accuracy. From a shooting precision point of view, there was great statistical significance of the employment of optoelectronic gunsight during dynamic shooting practices, namely on the vertical "y" - axis. Keywords: gunsight, shooting, assault rifle, target, laser

Title: Shooting disciplines for an air rifle Objectives: The aim of the thesis is describe the rifle disciplines for the air rifle, including changes from 2017. Methods: in this thesis was used content analysis of documents and other professional publications related to sport shooting by air rifle. Results: The result is an overview of the sport shooting of the air rifle, including their shooting disciplines, which are listed in the current rules of 2017, valid until 2020. Keywords: Shooter, discipline, rifle, target, aiming
