Monitoring deviations of body composition measurements on the InBody 770 device
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.

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.

Bioimpedance measurement
Pagáčová, Lenka ; Balogh, Jaroslav (referee) ; Sekora, Jiří (advisor)
The work deals with the body analysis using bioimpedance. The work included theory about bioimpedance and methods associated with the analysis. In the practical part is design of the device for measuring body composition including a software for the microcontroller. The assembled device was tested and compared with commercial product Tanita.

Methods of subcutaneous fat measurement
Marek, Vojtěch ; Harabiš, Vratislav (referee) ; Chlíbková, Daniela (advisor)
The thesis studies comparsion of methods of subcutaneous fat measurements. It briefly describes body composition, and deals with research of the most important methods. It describes used devices, which were used. It deals with statistical evaluation of measured data. This thesis approves, that results are different among the devices on statistically significant level, simultaneously there wasnt clear factor, that would have caused it.

Doplňky stravy pro optimalizaci sportovního výkonu
Musilová, Karolína
The diploma thesis forms an overview of the most commonly used dietary supplements in the MMA sports industry. The effects and metabolism of BCAA supplements and creatine monohydrate are discussed in detail in this thesis. These two mentioned supplements are also included in the practical part of the work, in which I examined their influence on the body composition of the probands. There is also a questionnaire survey that concerns strength during training and the subjective feelings of athletes during exercise while using selected food supplements. Measurement and evaluation of InBody outputs revealed changes in body composition during BCAA and creatine monohydrate use. I also managed to confirm an increase in strength during train-ing when supplementing with creatine monohydrate.

Comparation of posture of the body of overweight and obese people and problems associated with it.
Telska, Viktorie ; Křivánková, Markéta (advisor) ; Nováková, Pavlína (referee)
Title: Comparation of posture of the body of overweight and obese people and problems associated with it Objectives: The aim of the bachelor thesis is to compare the differences in posture between people suffering from overweight and obesity and to compare the difficulties associated with posture in these two groups. Methods: The method of determining the BMI value and the method of bioelectric impedance analysis of the body using the Tanita weight was used to determine the exact sample of probands and to divide them into the category of overweight and obesity. Furthermore, methods of evaluation of posture according to Jaroš and Lomíček, according to Klein, Thomas and Mayer and Trendelenburger's test were used. Lastly, a questionnaire survey method was used to identify difficulties in overweight and obese probands. Results: The results indicate a higher prevalence of wrong posture in obese probands compared to overweight probands. The incidence of musculoskeletal disorders was comparable in both groups of probands. The incidence of other disorders was more common in obese probands on average. Keywords: posture, inbody, backache, body mass index
