Anthropometric factors of Czech artillery soldiers
Šimsa, Jáchym ; Sýkora, Karel (advisor) ; Vokounová, Šárka (referee)
Title: Anthropometric factors of Czech artillery soldiers Objectives: The aim of this paper is to evaluate somatotype and body composition of Czech artillery soldiers. It compares three different methods of determining body fat and searches for an easily measurable and reliable predictor of low bone density, whereas evaluating correlations between selected anthropometric factors. Methods: Members of the 13th Artillery Regiment Jince were divided into three groups according to their classification, after which a stratified selection was used to maintain appropriate ratio of the groups. The study involved 189 men and 20 women (age 31.7 ± 6.4 years; height 178.4 ± 7.7 cm; weight 83.8 ± 13.6 kg). All participants were active professional soldiers at the time of the measurement. The data were obtained in the Jince Military Base and in the biomedical laboratory at the Faculty of Physical Education and Sports of Charles University. Each volunteer underwent four procedures - Heath- Carter somatotyping, Durnin-Womersley body fat estimation, a detailed bioelectrical impedance analysis (BIA) using Tanita MC-980, and a full-body dual-energy X-ray absorptiometry (DXA) using Horizon System. To determine mutual relations, Kendall rank correlation coefficient was used and the level of significance was set at p =...

Effects of single beta-alanine dose on performance at submaximal load
Šimsa, Jáchym ; Sýkora, Karel (advisor) ; Šteffl, Michal (referee)
Title: Effects of single beta-alanine dose on performance at submaximal load Objectives: The aim of this study was to investigate the effects of single beta-alanine dose on blood-lactate level in capilary blood and whether it will affect the speed of passing the test. Methods: A double-blinded cross-over study conducted on 16 male students of Military Department at the Faculty of Physical Education and Sports of Charles University (mean ± SD: weight 79,31 ± 6,97 kg; height 181,56 ± 6,36 cm; age 21,63 ± 1,45 yrs). The study was performed in Military Sport Centre Pilotů 217/12, 161 00, Prague. Each volunteer underwent two performance tests after consuming either placebo (maltodextrine) or beta-alanine (50 mg/kg). Time needed to complete the test and blood-lactate concentration before and during 5th and 10th minute after completion was measured. Volunteers also filled a short questionnarie regarding subjectively percieved load and side effects, and whether they were administered beta-alanine (BA) or placebo (PLA). For verification of normal distribution were used Q-Q Plots and statistical significance of BA use was determined using student's t-test. Results: Measured lactate concentrations were (mean ± SD; mmol/l) for BA in min 0 = 1,29 ± 0,37; min 5 = 11,48 ± 1,45; min 10 = 10,64 ± 1,76; PLA in min 0...
