Evaluation of the error rate of the InBody 770 and Bodystat 4000 devices in case of violation of the measurement conditions specified by the manufacturer.
Pevalová, Nicole ; Adamík, Richard (referee) ; Bedáňová, Kamila (advisor)
This bachelor thesis deals with the error rate evaluation of the InBody 770 and Bodystat QuadScan 4000 bioimpedance devices used for human body composition analysis. The theoretical part of the thesis contains technical knowledge about the individual instruments as well as a description of the bioelectrical impedance used by the aforementioned instruments for their operation. The practical part consists of measurements of subjects using both devices. The monitored variables are impedance, BFM (body fat) and TBW (total body water). The measurements consist of a reference measurement on each device separately and then four error measurements are made where the measurement conditions set by the manufacturers are not followed. The measured values of impedance, body fat total body water were statistically compared using a two-sample t-test. Instrument error was quantified using the mean relative deviation of the error measurements from the reference measurement.

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

Determination of body composition by bioelectrical impedance method in patients with chronic obstructive pulmonary disease
Sehnalová, Lucie ; Kovařík, Miroslav (advisor) ; Hronek, Miloslav (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Student: Lucie Sehnalová Supervisor of master thesis: PharmDr. Miroslav Kovařík Ph.D. Title of master thesis: Determination of body composition by bioelectrical impedance method in patients with chronic obstructive pulmonary disease Chronic obstructive pulmonary disease (COPD) is one of the top leading causes of death and its morbidity and mortality worldwide is still increasing. Besides the respiratory symptoms there are often developed alterations in metabolism and body composition in COPD patients. Clinically important are mainly malnutrition and skeletal muscle protein loss. Especially if the respiratory muscles are affected, the lung function is negatively influenced. The main aim of this study was to compare the body composition between 15 patients with COPD 3rd and 4th stage and 9 patients of control group without respiratory impairment and comparable anthropometric characteristics (age, body height and weight). By means of bioelectrical impedance analysis we determined the composition of main body compartments. In patients with COPD was the mean amount of lean tissue of body weight (rel LTM) 47.2 ± 8.4 %, amount of fat mass (rel Fat) 37.8 ± 6.4 % and mean overhydration (OH) 0.31...

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...
