Influence of a performance level of fencers on reaction time and actvation of selected muscels during a lunge
Balkó, Štefan ; Hendl, Jan (advisor) ; Havel, Zdeněk (referee) ; Šimonek, Jaromír (referee)
Title Influence of a performance level of fencers on reaction time and activation of selected muscles during a lunge. Problem The motion efficiency of offensive or defensive actions implemented during the match of fencing is related to the consolidation of movement patterns in the CNS through the training proces and competition situations. In this regard, muscle activation during a lunge, which is the most common form of attack, may be important for the resulting performance of fencers. The attack during a match is usually initiated by the occurrence of visual stimuli (eg. opponent's arm movement). Throughout the training proces and practise, in which are the given model situations repeated, occurs a creation of a specific purpose motion program stored in memory. Fencers are during the match often exposed to situations where they have to respond simultaneously to multiple stimuli that have to be adequately evaluated. The appropriate response may be associated with the movement or ignorance of stimuli, therefore will this work also deal with the level of complex reaction time. When measuring complex reaction time so-called "additional" stimulation will be used, it is increasing the number of stimuli, but should not lead to physical reaction of the fencer. The results of the present work related to...

Identifying a genetic predisposition affecting sports performance, focusing on anaerobic activity of skeletal muscle activity
Balkó, Iva ; Kohlíková, Eva (advisor) ; Šimonek, Jaromír (referee) ; Zvonař, Martin (referee)
Title Identifying of genetic predisposition affecting sports performance focusing on anaerobic activity of skeletal muscle activity Problem Inborn predispositions of every individual are mainly influenced by the inherited genetic information in their DNA with the addition of external environmental factors. Based on the high variability of the inborn predictions in the form of phenotypic differences in the anatomy or physiology of an individual, it can be deduced on the connection between genetics and a specific sport talent. According to current scientific knowledge, anaerobic performance of the skeletal muscle tissue seems to be more genetically influenced. Anatomic and functional properties of the skeletal muscle are mainly influenced by genes, which have effect on the muscle fibre structure, blood storage, metabolism, neurotransmission, and muscle regeneration, etc. Fencing is a complex sport discipline where predispositions to speed and dynamic force play a key role. The sport performance in fencing, regardless of the type of weapon, is directly dependent on the interactions between the reaction of the fencer to the surrounding stimuli (visual, tactile), accuracy, tactical and technical skills, level of anticipation and overall physical a psychological readiness of the fencer. This work is...

The Genetic predisposition of a speed ability among the players of the 1st and 2nd Czech football league
Thiel, Dan ; Petr, Miroslav (advisor) ; Šimonek, Jaromír (referee) ; Pupiš, Martin (referee)
Title The genetic predisposition of a speed ability among the players of the 1st and 2nd Czech football league. Study aim To determine the impact of ACE I/D, ACTN3 R577X, AMPD1 Gln12X, BDKRB2 9/+9, IL1RN VNTR, NOS3 Glu298Asp, UCP2 Ala55Val polymorphisms genotype frequencies on the results of the speed ability motor tests. Methods DNA samples obtained from epithelial mouth were quantified and analyzed using the PCR method from 106 football players of the 1st and 2nd Czech football league (age 25,3 ± 4,69; weight 77,5 ± 7,33; height 181,2 ± 6,23). Genotype frequencies were estimated for the ACE I/D, ACTN3 R577X, AMPD1 Gln12X, BDKRB2 9/+9, IL1RN VNTR, NOS3 Glu298Asp, UCP2 Ala55Val polymorphism. Motor speed ability was tested by the vertical jump height, produced power and power impulse for the countermovement jump, countermovement jump without arms swing and squat jump. Isokinetic maximal power of flexors and extensors of the knee were tested at the angle speed 60ř.s-1 , 180ř.s-1 , 300ř.s-1 . Χ2 test (Pearson's chi-square test) was used to determine the genotypes difference for the parameters of the motor speed ability tests in the football players who exceeded 80th percentil compare to the other football players. Kruskal- Wallis test was used to determine dependence (p = 0,05) of the genotypes...
