Organism physiological response on carried load in military
Absolon, David ; Michalička, Vladimír (advisor) ; Šteffl, Michal (referee)
Title: Physiological response of the organism to the load carried in the military environment. Objectives: Identify commonly used methods of measuring physiological response to load bearing in selected armies. Methods: The method used for the development of this bachelor thesis was a systematic search method based on a referred selection of items in accordance with PRISMA recommendations. After defining the research question and the objectives of the thesis, the results were retrieved through the internet databases (Web of Science, Scopus, PubMed) by means of a script we developed, from which we then selected the most suitable studies for data processing and subsequent synthesis under predefined parameters. Finally, studies were subjected to validity checks using hodnocení metodické kvality parameters. Results: The aim of this bachelor thesis was to use a systematic review method to ascertain commonly used methods of measuring physiological response to load carried in the military environment. Twelve studies were selected that were directly related in their content to the essence of this thesis, it is the measurement of the physiological response of the organism to the load carried. After the analysis of these studies, an overview of the data obtained was created. In each study, the authors...

Effects of isokinetic strength and postural muscles on dynamic strength, velocity and angular velocity of a front kick with and no carried load.
Krajcigr, Jan ; Vágner, Michal (advisor) ; Oláh, Vladan (referee)
Title: Effects of isokinetic strength and postural muscles on dynamic strength, velocity and angular velocity of a front kick with and no carried load. Objectives: The aim of the work was to find the effect of the isokinetic strength of hip and knee flexors and extensors of the lower limb performing a front kick, hip rotators during concentric and eccentric contraction of the standing lower limb and the postural muscles on dynamic forces, velocity and angular velocity of a front kick with and no carried load. Methods: This correlation study was conducted on 16 male participants (age: 22 ± 1,5 years⁏ weight: 79 ± 6,6 kg⁏ height: 182 ± 6,1 cm) studying military physical education at the Faculty of Physical Education and Sports of Charles University in Prague. Participants performed 5 consecutive front kicks with or without additional load (0 kg, 5 kg, 15 kg, 30 kg, 45 kg). The dynamic strength of the kicks was measured using a Kistler force plate. The velocity and angular velocity of the kicks were measured using a motion capture system (Qualisys). The isokinetic strength of hip and knee flexors and extensors and hip internal and external rotators were measured using a Humac Norm isokinetic dynamometer (CSMI). Postural muscles strength was assessed using 5 different stability tests. The correlation...

Systematic review of the influence of lower limb and trunk strength on aerobic performance during loaded marching
Pustka, Martin ; Sýkora, Karel (advisor) ; Vágner, Michal (referee)
Title: Systematic review of the influence of lower limbs and trunk strength on aerobic performance during loaded marching Goals: On the basis of a literature review, find out what is the relationship between the lower limbs and trunk strenght and between the aerobic performance during loaded marching. Alternatively, to determine the effect of the development of strength skills of the lower limbs and trunk on aerobic performance during loaded marching. Method: The presented study is processed in the form of a systematic search with correlation elements. The Web of Science database was selected to search for articles. The search was performed using a search script that had four parts. The last part of the search script generated 44 articles. These articles were then analyzed and studies were selected according to predetermined criteria. From the 44 generated studies, two were selected that met all criteria. Another six selected studies were then sought in an unsystematic way. Thus, a total of eight studies were included in the search. Conclusion: The results of the correlation coefficients between the lower limbs and trunk strenght and between the aerobic performance during load marching indicated in most cases a positive relationship, although the values were not completely significant. The increase...

Appropriateness of choice to walk or run, depending on the speed of a quick relocation with load carriage
Kopřiva, Jiří ; Fedák, Josef (advisor) ; Baláš, Jiří (referee)
Title: Appropriateness of choice to walk or run, depending on the speed of a quick relocation with load carriage Objectives: Comparison of physiological response of organism during the walk and run at speed 6 - 7,4 km.h-1 with carried load 15 kg with follow-up determination of critical speed in connection with economy of these activities where there were discovered sizes of correlation with proportional representation of fat free mass and working length of lower limb. Methods: The method applied in this research was the quantitative research based on intra-individual and inter-individual comparative analysis. Results: Based on the measured data it has been found out that there is a critical speed at 7,43 km.h-1 (±0,53), with respect to economy of walk compared to run with 15 kg load. The average heart rate during the critical speed was 129 BPM (±9,67). The average energy expenditure per minute during the critical speed was 11,9 kcal (±2,04). In addition there were discovered sizes of correlation between critical speed and the working length of lower limb where rP = 0,9203 was statiscitally significant. (α = 0,05) and between critical speed and proportional representation of fat free mass, where rP = 0,1529 was not found to be statistically significant (α = 0,05). Keywords: quick relocation, load...

Prediction of performance with software Combatfit
Štefanský, Michal ; Barták, Erik (advisor) ; Kubový, Petr (referee)
Title: Prediction of performance with software Combatfit Aim: Describe functions of software Combatfit. Copmare calculation of Combatfit with terrain measurement. The methods used: The thesis is empiric - teoretic research and it is consist of two parts. 1)Teoretic part - analytic work 2)Empiric part - metodologic study Results: The objective of research was time of run on 8 km trail with 10 kg of external load. Measured time was compared with time of software Combatfit prediction, which is based on entrance exams. Results shows that prediction is noticeably differ from measured time. Also it was investigate rate of relation tightness between prediction and measured time. Relation tightness work out low, against expectation. Prediction of software Combatfit is inaccurate. This statement is certain for test aggregate, nevertheless it is not sure, if same conclusions will be reach for other performance groups. Key words: Software Combatfit, prediction of performance, movement, external conditions, load carriage.
