Comparison of somatotype profiles in ice hockey players of national team 1976 and national team U19 season 2017-2018
Rybársky, Matej ; Musálek, Martin (advisor) ; Kinkorová, Ivana (referee)
Title: Comparison of somatotype profiles in ice hockey players of national team 1976 and national team U19 season 2017-2018. Objectives: The main aim of this thesis is to compare the level of somatotype profile changes between national team of Czechoslovakia from 1976 and Czech republic national team U19 playing in season 2017-2018. Methods: For purpose of study the observation research method was used. Research samples were made of 41 ice hockey players, specifically players of Czechoslovak national team from 1976 (n=24) and players of Czech national team U19 in season 2017-2018 (n=17). The somatotype was determined using Heath and Carter method (1990). To determine the degree of differences between the given parameters, the effect size of Cohen d was used, d ≥ 0,5 a d ≥ 0,8 depending on the hypothesis formulated. Results: Results showed, that the endomorphy of U19 players was significantly greater compared to ČSSR 1976 players (Cohen d = 0,65). The biggest difference was revealed at supraspinale skinfold (Cohen d = 1,06). On the other hand, we found significantly lower mesomporhy in U19 players (Cohen d = 1,63). The cause of this lower mesomoprhy was mainly due to significantly lower bone robusticity of the humerus (Cohen d = 0,81) and femur (Cohen d = 1,19). Keywords: somatotype, ice hockey,...

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
