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.

The influence of diet on the absence and recovery of the menstrual cycle
MARTINÁSKOVÁ, Markéta
The aim of my Bachelors thesis was to find out what effect diet has on menstrual cycle loss and what effect diet has on menstrual cycle repair. Eating disorders, malnutrition, alternative diets, low body fat, hormonal contraceptives, stress, reduced energy intake and excessive physical activity can have a negative impact on the menstrual system. One of the most common forms of secondary amenorrhea is functional hypothalamic amenorrhea. Low level of estrogen occur, which has a negative effect not only on the reproductive system of women, but also on their overall health. Secondary amenorrhea that lasts 6 months or more results in thinning of the bones (osteoporosis) in postmenopausal age. Early therapy is necessary for the proper function of the female reproductive system. In the practical part, I evaluated a questionnaire of my own design and analyzed the diet records from respondents who have faced or are facing loss of menstrual cycle. The results of my questionnaire investigation confirm the negative impact of the above mentioned factors on menstruation. More than half of the women interviewed have experience of eating disorders. Almost 1/3 of the women are on a reduction diet. The daily energy intake of some of the respondents is below 1500 kcal. The vast majority of the women participate regularly in sports. More than 1/2 of the women experience frequent fatigue, stress and were facing difficult life situation at the time of loss of menstruation. Only less than 1/4 of the respondents use hormonal contraceptives or have an IUD in place. According to the questionnaire survey, more than half of gynaecologists do not deal with loss of menstrual cycle. After evaluating individual diets, it is clear that loss of menstrual periods occurs with low energy intake. By increasing energy intake, menstruation returns.

Intersexual differences of adiposity markers in contemporary Czech children aged 11 - 15 years
Auxtová, Martina ; Sedlak, Petr (advisor) ; Zamrazilová, Hana (referee)
Thesis is focused on the analysis of intersexual differences in adiposity markers within urban population of Czech children from 11,00 to 15,99 years. This age range encompasses puberty which is one of the critical periods for the possible development of overweight and obesity. The sample PRAHA 2013 consists of 356 girls and 353 boys which were surveyed for basic anthropometric indicators - body height, body weight, BMI, mid- upper arm circumference and the thickness of four skinfolds. Intersexual differences discovered in measured parameters show statistical significance (p<0,01 resp. p<0,001) and it corresponds with the characteristic changes of pubertal development in both of genders. Testing file PRAHA 2013 against reference standards and its comparison with the results of the last Czechoslovak spartakiade in 1985 points to positive secular trend of increasing body height. However increase in weight parametres is still continuing. Probands from the year 2013 reach higher body weight values, BMI and skinfold thickness in comparison with children of the same age in 1985, 1991 resp. 2001. Significant differences were found out in the most of age categories in both of genders. Keywords: adiposity tissue, subcutaneous fat, skinfolds, body fat distribution, sexual dimorphism, obesity, secular trend

Adipose tissue distribution by preschool children- comparative study
Petrů, Dominika ; Dylevský, Ivan (advisor) ; Adámková, Věra (referee) ; Navrátil, Leoš (referee)
CHARLES UNIVERSITY IN PRAGUE FACULTY OF PHYSICAL EDUCATION AND SPORT ADIPOSE TISSUE DISTRIBUTION BY PRESCHOOL CHILDREN- COMAPARATIVE STUDY ABSTRACT Head of the dissertation: Author: Prof. MUDr. Ivan Dylevský, DrSc. Mgr. Dominika Petrů Prague, 2014 Abstract The dissertation provides information about the distribution of subcutaneous adipose tissue in preschool-aged /5-6 years, n=141/ and younger school-aged children /8- 9 years, n=137/ in the Ústí region. In this review, we describe and evaluate the child's body with anthropometric parameters, skinfold, bioelectrical impedance analysis and selected sample /n=31/ with ultrasonography. We found an increased distribution of adipose tissue in older file with a concentration in the abdominal area and a higher reliability of skinfold than the BIA, considering the ultrasound examination. Key words: subcutaneous fat, skinfold, bioelectrical impedance analysis, ultrasonography
