Didek, Zdeněk ; Oláh, Vladan (advisor) ; Prokešová, Eva (referee)
Title: Effects of Height and added Load on kinematic drop vertical jump in Military Personnel. Goal: This research investigated how added load affects the kinematics of lower extremities during drop vertical jump from different heights in military personnel. Methods: The character of this thesis was theoretical and empirical. It was a randomized trial with a cross-over design. The research population consisted of 23 army students (21.8 ± 1.8 years, 182.1 ± 9.4 cm 82.3 ± 7.2 kg) of Faculty of Physical Education and Sport of Charles University who performed jumps and subsequent lunges (drop vertical jump) from a height of 50 and 75 cm without non-PNZ and with PNZ (21.45 kg) of load carry. Dartfish (10.0) was used for dynamic valgus analysis. The data obtained were descriptively and statistically analyzed in Jasp (0.16.2) using repeated measures analysis of variance. The level of statistical significance was set at α=0.05. Eta-squared was calculated at η2 =0.066 and Cohen's d at d=0.626. Results: There was no evidence of main effect of load bearing with different jump heights on dynamic knee valgus. The descriptive statistics yielded only positive values for knee angles, indicating only dynamic varus. However, the effect of load carry and jump height on lower limb kinematics showed the following...
Specifics of laser and real firing from a small arms

Title: Specifics of laser and real firing from a small arms. Goal: The aim of this study to gather information about real and laser shooting from small arms in connection with human physiology and biomechanics. The main benefit of a systematic grasp of the issue as an understanding of comprehensive information. To compare their differences, or to eventually laser-shooting as an instrument for testing soldiers in the Army of the Czech Republic. Methods: Literature search, which deals with the issue of shooting. For the elaboration of this work, the search for study sources was used, followed by their analysis and subsequent search of these obtained study sources. Results: The result of this work is a comprehensive understanding of shooting from real and laser weapons in terms of biomechanics and human physiology and its impact on shooting performance. When comparing real and laser shooting, no significant penetration into the issue was found due to the insufficient number of sources and information about laser shooting. For this reason, a greater representation of the laser weapon cannot be justified in this work at the expense of the real weapon in the Army of the Czech Republic system, even though the use of laser weapons in training is a cheaper financial issue in the long run. Key words: Army,...
