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...
