Body Posture in Disco Dance Performers
Svobodová, Alice ; Šteffl, Michal (advisor) ; Hráský, Pavel (referee)
Title: Body Posture in Disco Dance Performers Objective: The aim of this master's thesis is to examine how the body posture of disco dance performers changes with over eight years of competitive experience and to identify periods when the most significant deviations in body posture occur. The study compares the results of individual case studies among female participants and seeks to shed light on the issues of body posture specific to the disco dance style. Method: A qualitative research approach was employed, focusing on a deliberate selection of participants - disco dance performers. Selected tests assessed body posture using the methods of Mathias, Klein Thomas, and Mayer. Results: The master's thesis revealed that girls with over eight years of competitive experience often encounter issues related to pelvic tilt, specifically, 6 out of 8 girls exhibited anterior pelvic tilt as the most common finding. Another frequent problem was lordotic curvature of the spine, identified in 4 out of 8 girls facing this issue. The most pronounced deviations in body posture were observed in a 13year-old participant who obtained negative results in the Mathias test. Conclusion: Qualitative investigation suggested that crucial factors influencing body posture may include overloading and a high number of weekly...

Corrective exercises for injury prevention in ice hockey players
Steklík, Aleš ; Šteffl, Michal (advisor) ; Novák, Dominik (referee)
Title: Compensatory exercises as one of the possible tools for injury prevention in ice hockey players Objectives: The aim of this thesis was primarily to identify and describe the most common injuries occurring in ice hockey players based on professional articles and available literature. Subsequently, the work was aimed at creating a stack of compensatory exercises (relaxation, strengthening, stretching) that could lead to a reduction in the risk of injuries. Methodology: The work was based on an empirical character. The findings from the literature were used. On the basis of the literature, consultations with physiotherapists and own experience, compensatory exercises were designed, which focused on the prevention of injuries in ice hockey players or on the elimination of imbalances or on exercises typical for the development of ice hockey players. Conclusion: Based on the literature and articles, it has been found that the most common injuries in ice hockey players are due to overload and contact with an opponent. Ice hockey players spend most of their time on the ice during games or training or spend time on conditioning. However, they forget about compensatory exercises. As a result, muscle imbalances occur due to unilateral loading and this causes many negative changes in the musculoskeletal...

Šplíchalová, Dominika ; Petr, Miroslav (advisor) ; Šteffl, Michal (referee)
Title: Analysis of selected gene variants in athletes - runners at 400 m Objectives: This work aims to find out what the genetic profile of athletes - runners at 400 meters, who are working in lactate mode, looks like. Methods: A cross-sectional investigation involved 203 East European Caucasian males and was conducted collaboratively at the FTVS UK and Józef Piłsudski University of Physical Education in Warsaw (AWF Warsaw). The athletes, after a brief warm- up, participated in a single 30-second Wingate test. DNA samples were collected non-invasively through saliva swabs. Lactate levels were measured using an invasive approach. Results: In the polymorphisms rs4646994 gene ACE was found to have a significant difference in genotypic (p = 0.001, x2 = 14.90) and allelic (p = 0.004, x2 = 8.52) frequencies between the overall athlete group and the controls. A notable difference in the ACE gene showed the comparison of the genotypes (p = 0.001, x2 = 13.66) and between the alleles (p = 0.003, x2 = 8.89) between the control group and elite athletes. The last statistically significant difference was observed among the genotypes (p = 0.03, x2 = 6.79) between the sub-elite athletes and the control group. When assessing the genotypic and allelic frequencies for the polymorphisms rs1815739 in the ACTN3 gene, we...

Title: Impact of the COVID 19 infection on the respiratory and cardiovascular system, physical strain during the course of the disease Aims: The primary aim of this thesis is to find and study the latest relevant findings regarding the impact of COVID 19 infection on the respiratory system, cardiovascular system and the effect of physical strain on the course of this disease. Subsequently, to write down a critical review on the topic. Methods: A literature review on the impact of COVID 19 infection on the respiratory system, the cardiovascular system and the effect of physical strain on the course of the disease. Results: The impact of the COVID 19 infection on the respiratory system is considerable. The disease can be asymptomatic or with only mild symptoms, typically shortness of breath and cough. The main manifestation of a developed infection is bilateral covid pneumonia, which progresses to ARDS in approximately 20-30% of hospitalized patients. The impact of the disease on the cardiovascular system is increasingly debated. Sources describe elevation of troponin in the serum, as an indicator of myocardial damage, in up to 12% of all cases. It can manifest as myocarditis, arrhythmias, myocardial infarction, cardiogenic shock or even heart failure. The infection of COVID 19 is a multisystem...

Přibylová, Anežka ; Psohlavec, Lukáš (advisor) ; Šteffl, Michal (referee)
Title: The relationship between personality traits and acute stress response during challenge activity Objectives: The aim of this study was to assess the influence of personality traits on coping with acute stress in overcoming a high obstacle. Methods: The study involved 27 undergraduate and graduate students from the Faculty of Physical Education and Sport (FTVS) at Charles University, with an average age of 23 years. The influence of personality traits on coping with acute stress during walking over a high obstacle was evaluated. Personality traits were assessed using the Big Five Inventory-44 questionnaire. The monitored indicators of acute stress response included heart rate, oxygen consumption, and respiratory rate. The results were processed using the software program Jamovi 2.3.26 solid. To determine the relationship between personality traits and acute stress response, Spearman's correlation coefficient was used. Results: A moderate correlation was found between neuroticism and heart rate (r = 0.53; p = 0.042) and between extraversion and respiratory rate (r = 0.526; p = 0.044) in the female sample. The male sample did not show any significant statistical significance between the individual personality traits and indicators of stress response. Conclusion: In our study, it was found that...
