Ondráčková, Eliška ; Kinkorová, Ivana (advisor) ; Macas, Tomáš (referee)
Title: Sports nutrition supplements and their use among junior and senior rowers in Czech Republic Objectives: The main aim of this thesis is to compare the use of sports nutrition supplements in junior and senior rowers categories in the Czech Republic. Methods: In this thesis, a comparative study was used in which an online survey method was used in the research. Data was collected using a survey that participants completed independently online. The survey was placed in a Google forms environment. The link to the survey was disseminated among the research participants through social networking sites. Results: The results of the survey showed that 75 % of the respondents use sports nutrition supplements, with almost half of them using them more than once a week between 2 and 5 years. The required number of junior rowers did not participate in the survey, so we can assume that there are more rowers in the senior category than in the junior category. For this reason, the results of the survey were processed on rowers in general. The respondents use sports nutrition supplements most in the preparation period, and the most used supplements are protein preparations. The most frequently described observed effects of sports nutrition supplements are both a better feeling of performance and a feeling of...

Vašurová, Barbora ; Musálek, Martin (advisor) ; Kinkorová, Ivana (referee)
Theme: Morphofunctional characteristics and physical aktivity profile in Czech elite traceurs Aims: The aim of the work is to describe anthropometric and somatic characteristics and movement profile in elite Czech parkourists. Methods: The research group consisted of 20 men of the elite category of traceurs, (actively competing, n = 5, competing in community competitions, n = 8 and noncompetitors, n = 7). To obtain the necessary parameters, the following will be used: 1. parameters of body typology according to the somatotype methodology (Heath and Carter, 1967). 2. Parameters of body composition and bone health obtained from Dualenergy X-ray absorptiometers (DXA) according to Hologic methodology 3. Parameters of physical activity profile obtained from Actigraf GTX9 according to Actilife methodology. Results: The average somatotype of the evaluated traceurs was 1.8±0,7 - 4.9±0,9 - 3.0±0,7, which means classification into the category of ectomorphic mesomorphs and group B, characteristic of versatile gifted individuals. The traceurs' somatotypes were different with regard to their categorization. The highest values of the mesomorphic component were measured for the group of active competitors and the highest values of the ectomorphic component in the group of non-competitors. Parkourists had an...

Title: Body composition of the Czech national snowboardcross team Objectives: The aim of this work is to measure and evaluate body composition as a factor influencing sports performance in the Czech snowboardcross team and comparison with relevant data of foreign authors. Methods: We evaluated body composition data using whole-body BIA analysis (Bodystat 1500 monofrequency analyzer in the field), anthropometric examination (height, weight) and waist-hip ratio, indicating the risk of cardiovascular disease. At the same time, we recorded the age and length of training of snowboarders. We used statistical operations (arithmetic mean, standard deviation, minima and maxima, statistical and material significance) for data analysis. We also compared the data with the relevant results of national teams of Italy and the USA (Vernillo et al., 2016; Sands et al., 2021) and data from the untrained population (Schutz et al., 2002; Abe et al., 2018). Results: We found that the average BMI of the Czech national team in snowboarding is 24.49 ± 1.8 kg/m2 (men) and 23.95 ± 0.94 kg/m2 (women). The mean WHR is 0.8 ± 0.03 (males) and 0.72 ± 0.04 (females). The Czech representatives significantly (p ˂ 0.05) and materially (d ≥ 0.8) differ significantly from the untrained population in FFMI values of 21.6 ± 1.1 kg/m2...

Jehličková, Tereza ; Hráský, Pavel (advisor) ; Kinkorová, Ivana (referee)
Title: Improving the posture of a former volleyball player during a three-month intervention Objectives: The aim of the bachelor's thesis is to process a literature search, to introduce beach volleyball and clarify its problems in the possible emergence of muscle imbalances and postural deviations. Another goal is to choose a former beach volleyball player, to perform an examination of the musculoskeletal system. The main goal of this work is to compile, describe, apply a compensatory exercise program and verify its effect in terms of posture adjustment and interpret the results of the examination and the applied intervention program. Methods: The thesis is a case study of a former beach volleyball player with deviations from the correct posture, for which an intervention exercise program was compiled on the basis of musculoskeletal diagnostics. The program lasted three months and was aimed at compensating for poor posture and identified muscle imbalances. The program consisted of partial compen-satory training units, which included breathing exercises focused on activating the muscles of the deep stabilization system, relaxation, stretching and strengthening exercises, which were modified after mastering lighter variants. A comprehensive kinesiological analysis, functional tests of spinal mobility...

Vrba, Matěj ; Šteffl, Michal (advisor) ; Kinkorová, Ivana (referee)
Title: Influence of alcohol on the contractile properties of skeletal muscle Objectives: To identify the impact of alcohol to contractile attribute (Tc - contraction time and Dm - maximal displacement) m. rectus femoris. Method: The diploma thesis corresponds with empirically-theoretical based study. The research has a character of a quasiexperiment. The measured participants were consisted of students (n = 8) of Military Department (VO) and students (n = 3) of civilian (TVS) of attending full-time studies at the Faculty of Physical Education and Sport (FTVS) of Charles University (UK) in Prague. There were used the methods of descriptive statistics to describe it - rate position (arithmetic mean) and a measure of variability (standard deviation). Contractile attributes (Tc, Dm) were measured on the device TGM 100 at an electricity current intensity 80 mA. To analyse the normality of data was used Kolmogorov-Smirkov's test. For further calculations was used parametric method one-way ANOVA for repeated measurements were used statistical significance. For statistical processing was used computer program IBM SPSS Statistics 22 and the individual dose of alcohol relative to body weight was administered in three rounds at 20 minute intervals. Results: The average Tc was 33.23 ± 3.45 ms for the first...
