Analysis of selected physiological parameters of athletes during exercise
Ambrožová, Monika ; Kolářová, Jana (referee) ; Ronzhina, Marina (advisor)
Regular sport activity is considered as neccessary part of our lifes. Sport is reccomended for preventing various diseases, enhancing immunity system or for controlling weight and for enhancing conditions. However, how severaly is sport activity benefit for human health and when it becomes harmful for it? This work deals with possible negative effects of strenous excercise on human organism. In our case it is ultra-maraton and mountbiking. In following parts of this work it is tried to explaine metabolic changes and influance of strenous excercise on immunological and biochemical parametres. The parameters immunoglobulin A, M, leukocytes, creatinine, sodium and potassium ions and enzymes such as lactatedehydrogenase, creatinekinase and alanineaminotransferase were studied. The values of these parameters were obtained from the blood samples taken before and after the race. A 23 samples from a 24-hour cycling race and 24 run-of-the-run race samples per 100 km were examined. A matlab tool was created for statistical analysis of data. A huge increase in the number of leukocytes was found in both types of races. In the MTB, it is an increase from 5.75 ± 1.29 x 109 / l to 11.80 ± 3.08 x 109 / l, in the race from 4.99 ± 1.84 x 109 / l to 13, 20 ± 5.36 x 109 / l. IgA did not significantly decrease, on the contrary slightly increased. IgM values have not changed significantly in runners. Cyclists experienced a statistically significant reduction in the original amount of 60.23 ± 6.54 mg / dl to 52.60 ± 10.43 mg / dl. There were statistically significant changes in CK and LDH levels in the race. From the original CK values of 4.25 ± 2.74 kat / l, the activity of the enzyme increased by 50.09 ± 60.08 kat / l due to the race. LDH is not significantly different in the cycling race as well as in the ALT enzyme. In this case, there was no statistically significant change to either type of race. Concentration of potassium and sodium ions decreased significantly. In potassium, its concentration dropped from 5.61 ± 0.59 mmol / l to 4.57 ± 0.39 mmol / l. Sodium ions dropped from 138.22 ± 1.17 mmol / l to 137.00 ± 1, 75 mmol / l.

Preparation and Properties of LDH-related Mixed Oxides Deposited on Al2O3/Al Support
Kovanda, F. ; Jirátová, Květa
Deposition of thin active layer on Al2O3/Al supporting material (anodized aluminum foil) during reaction with aqueous solutions of various metal nitrates under hydrothermal conditions, as well as physical chemical properties and catakytic activity of the realted mixed oxides in total oxidation of ethanol was studied.
Low-temperature inorganic synthesis and photocatalytic activity of anatase TiO2 powders
Tasbihi, M. ; Štangar, U. L. ; Černigoj, U. ; Jirkovský, Jaromír
Nowadays, it is a great challenge to synthesize different crystalline TiO2 using low temperature methods without calcination step. In our study, the nanocrystalline titanium dioxide sols were prepared from TiCl4 under acidic conditions. The powder was obtained with consequent drying of the sols at temperatures below 100 oC and these samples were then characterized using different techniques. The results show that the properties of the asprepared powders depend mainly on the type of the acid and less on the amount of the acid. The usage of HClO4 instead of HNO3 as the peptizing agent results in colloids with higher photocatalytic activity
Aging of the TiO2 colloidal particles in water: effect on their properties
Paušová, Š. ; Krýsa, J. ; Mailhot, G. ; Jirkovský, Jaromír ; Prevot, V.
The quantum sized titanium dioxide particles (Q-TiO2) could be prepared by hydrolysis of TiCl4, the final pH is 2.5 and particle size around 7 nm. From the environmental point of view very promissing seems to be the application of new composite materials combining layeres double hydroxides (LDH) and Q-TiO2 nanoparticles. Due to the synthesis of LDH it is important to keep Q-TiO2 particles in alkaline pH without big change of their size.
