Pavelková, Pavla ; Kračmar, Bronislav (advisor) ; Vystrčilová, Martina (referee)
Title: A Comparative Kineziologic Analysis of the Javelin Throw and Selected Training Exercises Purposes: The goal of this study is to compare the engagement of selected muscles in the shoulder girdle area during javelin throwing and certain training exercises. Methods: Surface electromyography combined with cinematographic analysis using synchronized video recording. Results: The timing of muscle activation during javelin throwing (side stand) differs from that of certain training exercises. The studied exercises were: javelin throw from the frontal stand, ball throw from the side and the frontal stand, throw simulation using rubber expander and pulley. The timing is similar when different grip (so called fork grip) is used during side stand javelin throw. Key words: shoulder girdle, surface electromyography, kinematic analysis.

Functional investigation of players in football tennis
Pavlatová, Lenka ; Süss, Vladimír (advisor) ; Kočíb, Tomáš (referee) ; Kračmar, Bronislav (referee)
Název: Funkční vyšetření hráček nohejbalu Název v angličtině: Functional investigation ofplayers in football tennis Klíčová slova: Funkční testy, zatížení, nohejbal, trénovanost. Cíl práce: Cílem diplomové práce je popsat, na základě funkčních testů a monitorování srdeční frekvence, zatížení hráček v nohejbalu. Závěry: Zatížení hráček nohejbalu má převážně aerobní charakter, nezanedbatelné zastoupení má však i aerobně - anaerobní zóna. V provedeném měření nebylo zaznamenáno anaerobně -laktátové zatížení, ale můžeme se domnívat, že při vypjatých zápasech nebo ve vrcholných utkání, se budou hráčky nohejbalu v tomto pásmu pohybovat. Zjištěné výsledky ukazují na špatnou trénovanost hráček v oblasti vytrvalosti, avšak ve srovnání s výsledky SF z utkání, není asi příliš nutná. Předpokládali jsme, že zatížení v utkání v nohejbale má intervalový charakter. Z výsledků je patrné, že se nejedná o typickou intervalovou zátěž a tudíž nemůžeme hypotézu 1potvrdit. 5

Kinesiological Analysis of the Rowing Stroke
Zbořilová, Martina ; Bačáková, Radka (advisor) ; Kračmar, Bronislav (referee)
Title: Kinesiological Analysis of the Rowing Stroke. Objectives: The aim of this thesis is to obtain, to analyse and process the data on the activity and involvement of selected measured muscles, working during one rowing stroke - in the drive part and in the recovery part. Methods: The work is processed by a kinesiological analysis of selected movement of the rowing stroke, based on the determination of muscle activation. Electromyography method was synchronized with the video recording. Results: Based on the sequences of the muscle activation was described their order and sequence in the actual shot of the rowing stroke (drive phase and recovery). We have proved that in the rigorous technical performance are always activated the same muscles in the exactly same order. Individual deviations from the correct technique in measuring appeared and thus enable their correction. Keywords: Electromyography, stroke, rowing, muscles.

Kinesiolgy analysis of function selected muscles of upper limb after brest augmentation
Víšková, Anna ; Kračmar, Bronislav (advisor) ; Véle, František (referee)
Title: Kinesiologic analysis of function of selected upper limb muscles after female breast augmentation Objectives: The aim of this research is to analyze the functionality and scope of involvement of the injured muscles due to plastic surgical augmentation procedure at pre-selected physical activities before and after surgery a few months later (specifically, three months - the time the patient left the recovery) using a noninvasive surface electromyography (EMG). Methods: A Case Study measuring method of noninvasive surface electromyography in combination with the method of temporal phase shifts involved in the activation of muscle movement, accompanied by a support method of integrated EMG. Results: There differences have been observed in the timing of individual muscles measured during performing selected testing exercises before and after completion of the augmentation plastic surgery operatios. Furthermore, the possibility of the loss of muscle strength has been detected by some measured muscles and this has the potential to take over functions of damaged muscles. Key words: plastic surgery, female breast augmentation, surface electromyography, upper limb muscles, musculus pectoralis major

Houška, Ondřej ; Kračmar, Bronislav (advisor) ; Novotná, Irena (referee)
Název: Možnost ovlivnění pohybového vzoru jízdy na kajaku pomocí reflexního plazení dle Vojty The possibility ofinfluencing the kinesiological contents ofthe motion pattem ofkayaking by Vojta's reflex locomotion Cíl práce: Vyhodnocení vlivu reflexního plazení na kineziologický obsah pohybového stereotypu jízdy na kajaku Metoda: povrchová polyelektromyografie v kombinaci s plošnou kinematografickou analýzou pomocí synchronizovaného videozáznamu Výsledky: po stimulaci pomocí reflexního plazení dle Vojty byla zjištěna redukce činnosti m. latissimus dorsi během tažení pádla vodou a při jeho vytažení a naopak zvýšení jeho aktivity ve fázi zasazení pádla do vody a při přenosu nad vodou; dalším nálezem bylo zvýšení zapojení m. deltoideus během tažení pádla vodou; m. pectoralis major zvýšil svou aktivitu během přenosu pádla a naopak ji snížil v okamžiku vytažení pádla z vody Klíčová slova: reflexní plazení, povrchová elektromyografie, kajak 2

Comparative Analysis of Bipedal and Quadrupedal Locomotion
Kvítková, Zuzana ; Bačáková, Radka (advisor) ; Kračmar, Bronislav (referee)
Title Comparative Analysis of Bipedal and Quadrupedal Locomotion Purposes Comparison of biped s and quadruped s step motion and comparison of the aktivity of their m. latissimus dorsi and m. glutaeus medius during different kinds of locomotion. Method Surface electromyography combinated with kinematography analysis used synchronized video recording. Results The activity of upper limbs during the biped s walk showed its delay-action compared with activity of quadruped s anterior limbs. The character of the chosen muscles of upper limbs is stabilization because of action in the open kinematic chain. Quadruped s action is in the closed kinematic chain and chosen muscles of all his limbs have locomotive function like chosen muscles of biped s lower limbs. Key words Surface electromyography, quadrupedy, bipedy, musculus latissimus dorsi, musculus glutaeus medius
