Asymmetric strenght training and its impact on maximal strenght
Bouchal, Martin ; Jebavý, Radim (advisor) ; Blažek, Dušan (referee)
Title: Asymmetric strength training and its impact on maximal strength Objectives: The aim of my bachelor's thesis is to compare the impact of asymmetric and symmetric strength training on the development of 1RM in the bench press and deadlift exercises. Methods: Sixteen female participants took part in the research, who were divided into two groups, Experimental Group 1 and Experimental Group 2. Experimental Group 1, with n=8 participants, performed asymmetric strength training for a period of ten weeks. Experimental Group 2, also with n=8 participants, performed symmetric strength training for the same duration. After completing the intervention strength program, a post-test measurement was conducted, followed by the evaluation of the results. The data were analyzed using mean, standard deviation, and the significance of the results was assessed through ANOVA and Cohen's effect size coefficient. Results: On average, the group that underwent symmetric strength training showed greater improvement in the bench press exercise. Conversely, the group that performed asymmetric training demonstrated greater improvement in the deadlift exercise. Conclusion: The results indicate that asymmetric training can also have its justification in strength and conditioning preparation. Asymmetric loading can be...

The Trump Administration and Its Impact on Czech Foreign Policy
Bastlová, Renée ; Hornát, Jan (advisor) ; Raška, Francis (referee)
This thesis examines the impact of the Trump Administration on Czech foreign policy. The aim is to analyze the changes that have occurred and explain what they have meant for the Czech Republic. The thesis uses the method of foreign policy analysis to achieve its goals. In his campaign, President Trump criticized multilateralism and what he saw as an unfavorable position of the USA in transatlantic relations. He withdrew from a number of multilateral organizations and imposed tariffs on European imports to the US by which he limited free trade. Among other things, President Trump used an aggressive style when calling on NATO member countries to honor their pledge to contribute two percent of GDP to the common defense. Trump's approach to the transatlantic relationship posed a challenge, as his actions contradicted the main goals of Czech foreign policy, which are security, prosperity, and sustainable development. The relationship between the two countries is asymmetric, and the Czech Republic must adapt to changes in US foreign policy. On the other hand, due to the growing influence of China and Russia, the US has increased its presence in Central and Eastern Europe. This attention resulted in the Czech Republic's leadership in the 5G talks. At the same time, space has opened up for the creation of...

Cerebral laterality in birds and mammals, its behavioral correlation and evolutionary significance
Tureček, Petr ; Komárek, Stanislav (advisor) ; Němec, Pavel (referee)
Lateralization of brain is ubiquitous quality of vertebrate brain. In this paper we rewiev examples of brain lateralization in birds and mammals and it's behavioral impacts. Than we discuss possible evolutionary origins of these asymmetries and their evolutionary significance. We try to explain individual as well as population level lateralization. We propose, that population level lateralization can, in principle, arise just on the genofondal basis, if the organism itself contributes to the enviroment with the lateralized behavior. Lateralized sensory input on the other hand should stand on the advantages of synchronizing with other individuals due to the disatvantage of predictability of lateralized population. Keywords: Lateralization; laterality; population level lateralization; asymmetry; evolutionary significance

Role of genetic variance in speciation
Payne, Pavel ; Markoš, Anton (advisor) ; Rueffler, Claus (referee)
Sympatric speciation has received much attention both empirically and theoretically. However, the contribution of sympatric speciation to biodiversity remains unclear. One piece missing from the speciation puzzle is the plausibility of sympatric ecological divergence of species through adaptation in polygenic traits. I consider an environment consisting of two niches, where one value of the trait is advantageous in only one niche, and vice versa. The selection regime is described by a trade-off in viabilities between the niches. These polygenic traits can, and often do, involve epistatic interactions among and between loci, so that the contribution of the alleles to viability deviates from additivity. Epistasis then also affects the curvature of the trade-offs: predominant less-than-additive epistasis turns the curve towards concavity and predominant more-than-additive towards convexity. The curvature of the trade-off plays a crucial role in the evolution of populations. With a convex trade- off, extreme values of the trait are favored and the population tends to diverge, but relatively stringent symmetry in strength of selection within the niches and the niche proportions is necessary to maintain polymorphism. In this study I use two and three- locus haploid versions of Levene's model to...

Shape, size and proportions of lower limb long bones among human populations from Eneolithic to the Modern Era.
Šídová, Markéta ; Velemínský, Petr (advisor) ; Brůžek, Jaroslav (referee)
Differences in the lifestyle of various populations may lead to changes in the shape of the long limb bones. This involves a reaction to the degree of mechanical and environmental stress acting upon these bones. Our work examined changes in the shape, proportions and size of the lower limb long bones (femur, tibia) over roughly the past five thousand years, or more precisely from the later phase of the Early Stone Age up to the 20th century. We studied the femurs and tibias of a total 520 adult individuals − 313 males and 207 females − from seven different periods or rather archaeological cultures. Our evaluation was based on the external, linear dimensions of the bones studied. Biological parameters were evaluated in relation to sexual dimorphism and lateral asymmetry. We paid special attention to the degree of flattening of the proximal third of the femoral and tibial shafts. Sexual dimorphism differed in individual populations. We found the least statistically significant parameters of sexual dimorphism in the oldest, Eneolithic, samples. In contrast, both sexes differed in the greatest number of parameters in the Early Middle Ages. Lateral asymmetry was most frequently demonstrated for the width dimensions in the case of the femoral and tibial diaphyses, which are in complete concurrence with...

Pelvic asymmetry in relation to the human reproduction
Kodytková, Aneta ; Brůžek, Jaroslav (advisor) ; Bigoni, Lucie (referee)
This diploma thesis deals primarily with the existence of the asymmetry of the bony pelvis and the sexual dimorphism of the asymmetry of the pelvic canal, which is caused by different reproductive functions of each of the sexes. Furthermore, the correlation or linear dependence of the external pelvic and pelvic canal dimensions was investigated. The study uses 3D pelvic models created in Avizo 7.1 from CT images of the recent French population. The material consists of 74 probands, of which 36 are males and 38 are females. The models were digitalized using Viewbox 4 software, in which 29 landmarks were applied to each pelvic model. These correspond to 24 dimensions divided into three groups: the size of the non-canal pelvis, the dimensions of the pelvic canal and the dimensions for calculating the correlation between the non-canal pelvis and the pelvic canal. The degree of asymmetry was evaluated using the formulas for the calculation of directorial (DA) and absolute (AA) asymmetry. Student's paired t-test was used for statistical analysis of asymmetry to determine asymmetry in previous studies. Gender differences were determined by the Mann-Whitney U test. At the same time, an analysis using the mixed model ANOVA was also performed, which in addition incorporates an intraobservation measurement...

Monitoring of the relationship between the asymmetry of facial skeleton and the soft tissues based on computed tomography
Skryjová, Zuzana ; Velemínská, Jana (advisor) ; Bigoni, Lucie (referee)
The human face is not perfectly symmetrical, slight asymmetries commonly occur in every individual across all populations. The aim of the work was to monitor the asymmetry on the entire surface of the soft and hard tissues of the heads of individuals with respect to age and sexual dimorphism. The follow-up goal was then to evaluate the difference in asymmetry between the tissues. The material for the work was a transverse set of CT images of the adult Czech population in the age range of 21-84 years. Individuals were divided according to gender into 50 men and 48 women and according to age into groups up to 39 years, 40-59 years and over 60 years. Geometric morphometry methods (CPD - DCA, asymmetry analysis, per vertex T-test, superprojection methods) were used for data analysis. The results were visualized using color maps and significance maps that show asymmetry and statistical significance. The variability of the file was analyzed by principal component analysis. The results of the evaluation of hard tissues showed a right protrusion on the anterior and lateral surfaces of the skull, in both men and women at all age intervals. This asymmetry was statistically very significant, in contrast to the posterior region, which was evaluated protrusion on the left side and had lower p-value. On the soft...
