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,...
