Dietary supplements in sport nutrition and possibilities of monitoring their effect on efficiency of sportsman.
Vlčková, Lenka ; Hrstka, Miroslav (referee) ; Vránová, Dana (advisor)
This work deals with dietary supplements intake and its impact on the performance rise and muscle mass growth of bodybuilders. Twenty-five students (bodybuilders) were chosen for the purpose of this survey; they were divided into four groups according to the dosage of creatine and other dietary supplements (proteins and maltodextrine). Changes of the measured parameters (weight; bustline; weistline; limb girth; body lipid content; creatine and urea content in the urine) were compared during the survey. The tested dietary supplements impact on the muscle mass growth was evaluated on the basis of the acquired results.

Spray &Trap Method for Analysis of Residual Toxic Agents in Water
Vlčková, Lenka ; Podborský, Vladimír (referee) ; Brno), (VTÚO (advisor)
This work deals with verification of the analysis of precursors or degradation products of toxic compounds in the air and water through GC/MS by method of the thermal desorption or combination of methods "spray & trap" followed by the thermal desorption transfer the sample into the analyzer. Toxic compounds triethyl phosphate (TEP) and diisopropylmethyl phosphonate (DIMP) were choosen for the analysis. For choosen compounds has been optimized desorption time, for TEP 240 seconds and DIMP 210 seconds. Then the calibration curve was made for different concentrations of compounds DIMP and TEP. On the basis of these measurements was tested the possibility of determining the concentration of the compound in water sample using of method "spray & trap“. Thanks to the high solubility of compounds TEP and DIMP in water, higher boiling temperatures in comparison with boiling temperature of water, and extraction at room temperature, it was not possible to detect used compounds. Therefore, the analysis of compounds DIMP and TEP in the water by method "spray & trap“ seems inappropriate.
