Kashkina, Aleksandra ; Bátorová, Michaela (referee) ; Adamík, Richard (advisor)
The bachelor thesis focuses on monitoring variations in body composition measurements using the InBody 770 instrument, which uses bioelectrical impedance (BIA) technology. The theoretical part of the thesis includes technical information on body composition components, a description of the principle of bioelectrical impedance and an introduction to the InBody 770. The practical part includes a pilot measurement, the results of which served as the basis for the main measurement. The main measurement involved three types of interventions: physical contact, application of a fat cream and drinking one liter of water. The measured values were analysed and evaluated using statistical tests. The results showed that each of these interventions had an effect on body composition.

Relation of body activities on composition of the human body
Frechová, Vendula ; Zemanová, Jana (referee) ; Vránová, Dana (advisor)
This bachelor thesis deal with relationship between physical activities and constitution of a human body. The first theoretic part is focused on components of foodstuff which are important for human nutrition, energy metabolism and different types of movement activity. The particular components of a human body such as body water, active body mass and body fat are described in the next part of the thesis. Diagnostic methods of human body’s constitution are mentioned in the last part. An analysis of a body constitution has a task to diagnose body components quantitatively and therefore provides main information about fitness. The practical part of the thesis contains influence of physical activity on body constitution, which was tested on the first group of people, and a study of eating manners of the second group of people.

Use of bioelectrical impedance analysis to determine composition of a body
EXNEROVÁ, Karolína
The topic of this thesis is "Use of bioelectrical impedance analysis to determine composition of a body". Measurement using bioelectrical impedance is considered an easily accessible, non-invasive and financially acceptable method of determining body composition, which is used to assess nutritional status, create diets and training plans. The theoretical part first deals with body composition, then describes in detail the bioelectrical impedance method. In the practical part, data collection was performed using a quantitative method. The research included 30 respondents who were recruited through social media or personal invitation to participate. The main objective of the work was to describe and determine deviations in the measurement of body composition using bioelectrical impedance methods between the InBody and Bodystat devices. The secondary objectives were to determine the advantages and disadvantages of measuring on InBody and Bodystat devices and to analyze the diets of selected respondents. In the research, a significant average deviation of 202.8 +- 138.2 kcal was found between the devices in measuring BMR. After dividing respondents by age, a significant average deviation was found between the devices in BMR, with a higher value (264.9 +- 111.7 kcal) among younger respondents compared to older respondents (121.6 +- 130.0 kcal). After dividing respondents by gender, it was found that the devices differed significantly in measuring BMR and TBW. The average deviation in TBW was greater with men (1.7 +- 3.1 l) than with women (0.4 +- 1.6 l). The average deviation in BMR was greater with men (272.5 +- 124.1 kcal) than with women (141.9 +- 122.8 kcal). When assessing the advantages and disadvantages of the devices with respect to measurement accuracy and the amount of data, the positives for the InBody370s prevail, and with respect to manipulation with the device, the positives for the Bodystat1500 device prevail. The Nutriservis Professional program was used to analyze the diets. In most cases, the respondents' diets did not correspond to the principles of proper nutrition. Fats and proteins were largely overrepresented, while with almost all respondents a carbohydrate deficiency was found. The diet's uniformity was a frequent problem for the respondents.

Effect of Supplementation on Somatic Parameters
Kostikidou, Marianthi ; Kinkorová, Ivana (advisor) ; Heller, Jan (referee)
Author: Bc. Marianthi Kostikidou Title: Effect of supplementation on somatic parameters Objectives: The aim of this study is to evaluate the effect of a 60-day long supplementation with Tribulus Terrestris on the body composition of healthy men. Methods: This diploma thesis is a double-blinded experiment. The theoretical part was mainly processed on the basis of information from electronic sources in English and Czech language. The subjects of this study were within the range of 18-35 years old and were randomly divided into an experimental (TT1) and a control (TT2) group. We examined changes in basic anthropometric parameters (height, weight, circumferences, skinfolds) and body composition estimated by bioelectrical impedance (BIA). The statistical analysis of the data was evaluated using ANOVA. The level of significance was set to 0.05. Results: In TT1 we observed significant changes in anthropometric parameters. Changes in body composition estimated by BIA were not of statistical significance. Statistically significant changes in TT2 were noted in both anthropometric measurements and BIA. Changes in both groups could be caused by various factors. Keywords: ergogens, nutritional supplements, tribulus terrestris, testosterone, caliperation, body composition, bioelectrical impedance

Body composition of the Czech national snowboardcross team
Hanko, Michal ; Bunc, Václav (advisor) ; Kinkorová, Ivana (referee)
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...

Comparison of methods of basal metabolism determination
Kosková, Martina ; Coufalová, Klára (advisor) ; Hráský, Pavel (referee)
Title: Comparison of individual methods of basal metabolism determination Objectives: The aim of the work is to compare the individual methods of basal metabolism. These values were measured by indirect calorimetry, plethysmography, bioelectric impedance and predictive equations. Methods: The research was attended by 31 people, including eight men and twenty-three women. All participants of my research were aged 21-30 years. None of the participants was a professional athlete, they were all healthy and none of the women were pregnant or had menstruation. The indirect calorimetry, bioelectronics impedance device Tanita MC - 980 and BOD POD were used to collect the data. Basal metabolic rates were calculated from the prediction equations by Harris & Benedict, Fleisch's equation and Schofield's equation using measured anthropometric values. Results: The results of the methods that have been used for this group of people vary, but the difference is not significant. If we choose as a reference method indirect calorimetry, we can't replace it by any other method. The results for other methods are not significantly different, so we can replace one method with another, except indirect calorimetry. From calculations, we also found out that fat free mass greatly influences the results of basal metabolic rate...

Mareček, Ondřej ; Česák, Petr (advisor) ; Kinkorová, Ivana (referee)
Title: Body composition in patients with idiopatic inflammatory myopathies Objectives: The aim of this study was to compare selected parameters of body composition in patients with idiopathic inflammatory myopathies (IIM) with age- and sex-matched healthy controls (HC). Another objective was to evaluate the effect of selected clinical parameters in patients with IIM on the detectedvariability of the parameters of body composition and on physical activity of patients. Methods: The research sample consisted of 84 individuals (54 IIM, 30 HC). In anthropometry, we measured: body height (cm), weight (kg) and BMI (kg/m2 ). Using bioelectrical impedance analysis BIA 2000-M we obtained values: total body water (TBW in%), muscle mass (LBM in kg), body fat (BF in%) cell mass of lean body mass (BCM of FFM in%), and the proportion of extracellular/intracellular matrix (ECM/BCM). Using Lunar series iDXA we obtained values: muscle mass (LBM in kg), body fat (BF in %), bone mineral density (BMD in g/cm3 ), and visceral fat (Visceral in kg). To these measured values we added a questionnaire on physical activity Human Acitvity Profile (HAP). Statistics: T-test, Mann Whitney U test, Cohen's d, and Partialeta-squared. Results: Selected values (mean ± SD): body height: IIM 164.7 ± 9.1 cm, HC 170.3 ± 7 cm; body weight:...

Nutritional problems in patients with chronic graft-versus-host disease after allogeneic transplantation of hematopoietic cells
Michková, Petra ; Šťastná-Marková, Markéta (advisor) ; Novák, František (referee)
Introduction: Graft versus host disease (GVHD) is a serious medical complication following allogeneic hematopoietic cell transplantation (allo HSCT). It causes immunodeficiency and several organ damage and decreases survival time at two years after a transplantation. A nutritional intervention should be applied just before the transplantation, because a nutritional status significantly influences the post-transplant complications. A risk of malnutrition or metabolic syndrome can be assessed by several markers. A combination of laboratory, anthropometric, biometric and physical data is suitable for this purpose. In addition, a subjective questionnaire regarding eating habits and physical activity of the patients can be used. Objectives: This thesis deals with the patients with chronic GVHD (cGVHD) following the allo HSCT. The objective was to describe a nutritional status of the patients, to find out in which way a long-term immunosuppressive treatment affects a body composition and to describe the eating habits and the physical activity of these patients. Methods: 31 patients with GVHD and 24 patients after allo HSCT without GVHD participated in the research. A body composition (using bioelectrical impedance) and selected laboratory parameters in patients were assessed. A subjective health...
