Impact of gear and weaponry on posture in kneeling shooting position
Zdražila, Václav ; Vágner, Michal (advisor) ; Kubový, Petr (referee)
Title Impact of gear and weaponry on posture in kneeling shooting position Objectives The aim of this thesis is to find out the impact of gear and weaponry on posture in the kneeling shooting position. Specifically, this study examines the influence of carried load on posture, aiming stability and balance in the high and low kneeling shooting position variants. Methods This thesis has an empirical observational character. The shooting position was tested by Qualisys camera system and Kistler pressure plates. The measurment was performed on 16 Military department students with mean age of 23 years (standard deviation 2,63 years). Measurements were carried out in four levels, with no load, light load of 15 kg, mean load of 30 kg and heavy load of 45 kg. The measurement was performed on high kneeling variant and the low variant with elbow supported by the front knee. Intra-individual comparison of the results of each level was determined by a T-test. Results: The load in a form of gear and weapony had a statisicaly significant - negative influence on the kneeling shooting position posture. Gear and weaponry used for this study caused a lower trunk position, increased shoulders angle in the low variant, lesser aiming stability and balance control in the position. The bigger was the weight of gear and...

Effect of shooting stances on ballistic protection of the shooter
Zdražila, Václav ; Barták, Erik (advisor) ; Kubový, Petr (referee)
Title Effect of shooting stances on ballistic protection of the shooter Objectives The goal of this thesis is to develop a method which could measure ballistic protection, which is currently provided by a bulletproof vest to the shooter in a current shooting stance. This work also focuses on analysis of the currently used shooting techniques and shooting stances, comparison of protection they can provide, and last but not least, to fill the gap in literature, wich deals with this issue. Methods This is an empirical thesis of observational character. Shooting stances were tested on a camera system named Qualisys. The results were first processed by a program for 3D analysis, and the ballistic protection provided by the bulletproof vest in different positions was calculated in a program for 3D modeling. Results: From the measured data, it was found that changing targets to the left (for right- handed) the provided ballistic protection significantly changes to worse. Conversely, when changing targets to the right, the ballistic protection faired the same or slightly better than aiming forward. The worst results of all stances came from the side shooting stance in which the bulletproof vest provided almost no protection. Keywords Ballistic protection, shooting stances, Qualisys, 3d analysis, vital zone
