Nutritional deficiences in vegan endurance athletes
Knížková, Šárka ; Heniková, Marina (advisor) ; Koudelková, Kateřina (referee)
Aim: This study aimed to investigate whether vegan endurance athletes, specifically runners, experience nutritional deficiencies due to a purely plant-based diet. Partial goals were set to evaluate whether these athletes have sufficient energy intake and receive adequate macronutrients and risky micronutrients. Methods: The research was conducted as a pilot study for the extensive European project VEGANScreener. Based on the completed questionnaire and meeting the criteria, 11 participants (n = 11) were selected. The subjects underwent body composition analysis using bioimpedance, their resting energy expenditure was measured by indirect calorimetry, and blood was taken. The subjects then performed a 4-day food record (self-reported 4-day Dietary Record), which was analysed using new software. The complete dietary record was analysed for only eight subjects (n = 8). Nutritional data were analysed using the left-sided Mann- Whitney U test, which belongs to the group of non-parametric tests. The test was conducted at a significance level of α = 0.05. Results: The average BMI of the subjects was 20.87 ± 1.58 kg/m2. Two subjects (n = 2) had a lower body fat percentage than is adequate. The biochemical blood test results indicated a possible vitamin D and iron deficiency. When comparing actual energy...

Nutritional knowledge of patients after bariatric surgery
Uhrová, Kateřina ; Mottlová, Alena (advisor) ; Orbanová, Pavla (referee)
The bariatric surgery is regarded as the most effective treatment method of dangerous forms of obesity. Since the bariatric surgery is closely related to nutrition, it is thus necessary to emphasize the importance of good nutritional knowledge of patients that have undergone this type of surgery. The aim of this thesis was to examine the nutritional knowledge of patients that are at least one year after the surgery, or reoperation. To get relevant data, patients were examined using an anonymous questionnaire. The survey indicates that the patients have insufficient knowledge regarding the recommended protein intake. Furthermore, the examination exhibited, surprisingly, that men have statistically worse knowledge than women do as well as that the majority of patients does not know what the dumping syndrome is. The survey confirmed that the patients operated more than two and a half years ago have worse nutritional knowledge than the ones operated within such a period of time. Moreover, the examination did not identify problems regarding the correct food preparation, post- operational diet, and inappropriate eatables. In addition, it was discovered that about fifty percent of all the examined patients have sufficient knowledge of the post-bariatric surgery eating habits. Since the importance of...
