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...

Author: Bc. Aneta Strejciusová Supervisor: PhDr. Tereza Nováková, Ph.D. Title: Musculoskeletal disorders related to the soldier's occupation Objectives: The main goal of this work was to find out how the prevalence of musculoskeletal disorders is related to the performance of the profession among soldiers of the 13th Artillery Regiment of the Army of the Czech Republic. Another goal was to investigate which risk factors, according to the respondents, most often occur in the origin of their difficulties and to clarify the preventive strategies that the respondents most often use in practice. Methods: The research was conducted using a questionnaire survey. A questionnaire based on the standardized Nordic Musculoskeletal Questionnaire (NMQ) was used to obtain data. The research group consisted of 196 respondents, both male and female soldiers of the 13th Artillery Regiment of the Army of the Czech Republic, who answered questions related mainly to work-related musculoskeletal disorders. Subsequently, the data was analyzed and conclusions drawn. Results: 35,7 % of respondents had at least one experience with work-related musculoskeletal disorder. The most frequently reported problems during the last 12 months were in the area of the lower back, where they occurred in 24,5 % of all respondents. This...
