Importance of nutrition, mainly proteins, in power sports.
Šesták, David ; Bláha, Pavel (advisor) ; Martinča, Jozef (referee)
Heavy athletics is a great stress for a human organism. This stress has to be compensated by proper nourishment and proper relaxation. Higher intake of all nutrients is always linked to heavy athletics. Some nutrients, such as omega-3 fatty acids, iron, zinc and proteins have a unique role in strength disciplines. Especially proteins are considered by both amateur and professional athletes as the most essential for muscle building. It is questionable how much protein is needed and how does its quality (directly linked to digestibility and absorbency) differ in animal and plant proteins, or even in supplementations proteins. The types of nourishment proteins that are combined together and what type of training is preferred matter significantly. Other agents of high significance are evidently, with direct or indirect influence, carbohydrates, dietary fiber, fats, vitamins, minerals and drinking habits.

First measurements with U-probe on the COMPASS tokamak
Kovařík, Karel ; Ďuran, Ivan ; Stöckel, Jan ; Seidl, Jakub ; Šesták, David ; Brotánková, J. ; Spolaore, M. ; Martines, E. ; Vianello, N.
A complex electrostatic-magnetic probe diagnostics, baptized as ‘U-probe’, has been installed on COMPASS tokamak recently. Probe composes of two identical towers. Each tower houses 3 radially spaced sets of 3D coils, triple probe and rake probe – array of six Langmuir probes. The U-probe measures electric and magnetic properties of the filamentary structures in the edge plasma, particularly the floating potential profile and local magnetic field within the plasma filaments. Contribution presents first tests and results obtained.

U-probe for the COMPASS Tokamak
Kovařík, Karel ; Ďuran, Ivan ; Stöckel, Jan ; Seidl, Jakub ; Šesták, David ; Brotánková, J. ; Spolaore, M. ; Martines, E. ; Vianello, N. ; Hidalgo, C. ; Pedrosa, M. A.
A complex electrostatic-magnetic probe diagnostics, baptized as 'U-probe', is being prepared for measurement of properties of the filamentary structures in the edge plasmas of COMPASS tokamak. Probe will be composed of two identical towers. Each tower will house 3 sets of 3D coils, balanced triple probe and six single Langmuir probes each. The design of the probe is based on that of U-probe used on reversed field pinch RFX-mod and our combined electromagnetic probe at TJ-II stellarator. This new COMPASS diagnostic will measure vorticity and longitudial electric current of the plasma filaments. Analysis of the properties and, particularly, the correlation between filament vorticity and its current is expected to shed light into physics of filamentary structures in the tokamak plasma edge. The simulation of the probe surface temperature evolution as a function of expected incident heat loads within the COMPASS edge plasmas is presented.

Measurements of Ion Temperature in the Edge Plasma of the COMPASS Tokamak
Naydenkova, Diana ; Janky, Filip ; Weinzettl, Vladimír ; Stöckel, Jan ; Šesták, David ; Odstrčil, T. ; Ghosh, J. ; Gomes, R. ; Pereira, T.
The two-grating spectrometer, which has been developed for the ISTTOK tokamak, allows an estimation of the temporal evolution of both ion temperature and poloidal velocity of the edge plasma by analysis of Doppler-shifted and broadened CIII spectral lines at ~465nm. At the current phase of the COMPASS tokamak operation, the first measurements of ion temperature using the optical system based on the spectrometer were performed and first results are presented.
