Optimalization of parts bonded by hot crimping
Liškář, Ladislav ; Řiháček, Jan (referee) ; Lidmila, Zdeněk (advisor)
The thesis describes the procedure for verifying the conceptual ideas of the company. Design and production of prototypes, testing and evaluation, quantifying savings. Two variants of crimped bond were chosen. For each was length of shaft changed to three and four crimped grooves. These prototypes were tested in two static and one dynamic tests. Recommendation for company is continue with other phases of development for shaft with four grooves.

Evaluation of resting energy expenditure and body composition in obese patients
Jílková, Anna ; Matoulek, Martin (advisor) ; Zelinka, Tomáš (referee)
Introduction: The basis of obesity treatment is a conservative regimen based on a reduced diet and physical activity, individually set for each person. As the obese often show extreme deviations in body composition compared to individuals of normal weight, it is often difficult to determine their energy needs or determine their energy expenditure. The gold standard for determining resting energy expenditure (REE) is examination using indirect calorimetry (IC). This method can also detect deviations from the calculations of predictive equations, determine the degree of adaptation of the individual to low energy intake, and thus set the appropriate therapy. Objectives: The main objective of the work is the analysis and description of data on body composition and resting energy expenditure values of selected groups of obese individuals whose REE measurement results using indirect calorimetry reached a level below 95 % of the predicted REE calculated using the Harris Benedict (H-B) equation. The sub-goals are to describe the dependence of the size of some components of body composition on the size of the REE and to find out if the deviations between the number of the total measured REE and the REE calculated using H-B in the adapted group are significant. Methodology: For the research 71 patients of...

The effect of a weight loss on bone and energy metabolism in premenopausal women with obesity
Malinová, Pavlína ; Zikán, Vít (advisor) ; Michalská, Dana (referee)
Introduction: Current findings show that obesity may not only have a protective effect in terms of the osteoporosis development. Although higher mechanical load on bones in obese people increases bone mass density, inflammatory cytokines produced by adipose tissue, on the contrary, increase bone resorption. The reduction of body weight itself can contribute to the deterioration of the quality of bone mass. Aim: The main aim of the study was to evaluate changes in BMD and selected parameters of body composition during a 2-month strict very low-calorie diet (VLCD) and a subsequent 4-month low-calorie diet (LCD) in premenopausal women with obesity. Methods: The study was carried out at the workplaces of the III. Internal Clinic of the General University Hospital in Prague and the Institute of Endocrinology in Prague. Data were collected in the period from April 2021 to May 2023. 11 patients participated in the study with dietary intervention, data was processed from 10 of them. The average age was 44.1 ± 9.3 years, the average weight was 94 ± 10.4 kg. The control group consisted of 14 patients, 10 of them were included in the study. The average age in the control group was 40.7 ± 6.4 years, the average weight was 64.4 ± 7.5 kg. Patients of the intervention group were given a very low-calorie diet with...

Changes in fitness parameters after bariatric surgery
Černohlávek, Lukáš ; Matoulek, Martin (advisor) ; Kolár, Leoš (referee)
Introduction: Obesity is characterized as an excessive accumulation of fat that can impair health. Nowadays, obesity is considered to be a very serious problem that is becoming increasingly important as the number of obese people increases. One of the options for treating severe obesity is surgical treatment or performing bariatric surgery. These allow significant weight loss with a long-lasting effect, so they are a very good solution for highly obese people. Aim: The aim of this interventional study is to compare changes in fitness and body composition before and after bariatric surgery in patients in the bariatric patient register of the 3rd Internal Clinic of the General Faculty Hospital in Prague who underwent bariatric surgery in 2022. The aim is also to introduce in detail readers with obesity issues, especially with bariatric obesity treatment. Methodology: The monitored group consisted of 11 respondents from the register of bariatric patients of the 3rd internal clinic of the General University Hospital in Prague. For these 11 respondents, changes in fitness based on walking tests and changes in body composition using InBody measurements were evaluated before bariatric surgery and 3 months after surgery. Subsequently, from these 11 respondents, 5 respondents were selected, in whom it was...

Patients compliance during the process of weight reduction
ŠPAČKOVÁ, Kateřina
This bachelor thesis deals with patients compliance during the process of weight reduction. The thesis aims to chart patients compliance during the process of weight reduction. The theoretical part defines overweight and obesity and its variations, prevention, causes, diagnostic and treatment. The next chapter deals with compliance and definition of nutritional therapist and nutritional advice. The last chapter of the theoretical part describes recommendations for weight loss, specifically proportionate amount of energy, advice on nutritional and physical activities, also psychological recommendations for sleep. The practical part was founded on qualitative research, specifically case studies containing interviews, anthropometrical data, bioimpedance records and menus. In the beginning, there were eleven respondents taking part in the practical part but two of them resigned. Two research questions were raised upon the practical part. The first one tried to determine what factors are involved in patients compliance during the process of weight reduction. The second one tried to determine what is the real nutritional and energy intake during the process of weight reduction. Obtained data was later transcribed and later evaluated in the software program Nutriservis professional. Obtained data show patients abide by the recommended regime in different rates case by case as in active cooperation with it. Out of the most common factors determining patients compliance, we may highlight the support by close ones, checks up in nutritional counselling office, fear of illness or stress. Menu records show the real nutritional and energy intake of patients corresponds to the set-up reduction regime. Problems occurred case by case i.e. with fibre intake. Results of the thesis might be used as a source for education material or as a general guideline helping cooperation of patients in the nutritional counselling office.

Weight loss with the help of physical activities and healthy eating
KOPEČKOVÁ, Vendula
My bachelor thesis focuses on the topic of weight reduction. The aim is to set and verify a month-long program to reduce weight thanks to regular exercise and balanced healthy diet. Statistic methods, methods of exercise program application, rules of healthy eating, anthropometric measurements, and questionnaire were used to research how the intervention program affects body weight, muscle weight, the size of problematic body parts especially waistline and hipline. There were positive changes in the experimental group in connection with the intervention program. There were statistically important changes connected to weight loss, muscle weight, hipline, and waistline. On the other hand, there were no changes in the testing group which did not follow the intervention program. The effects of the formed program have been verified.
