Omcirk, Dan ; Tufano, James Joseph (advisor) ; Reguli, Zdenko (referee) ; Fernandes, John (referee)
Title: Evaluating Methods of Assessing Force and Velocity during Punching Specific Movements Objectives: This dissertation had three main objectives: 1. To determine the ability of different commercially available punch trackers (Corner, Everlast, and Hykso) to recognize specific punch types (lead and rear straight punches, lead and rear hooks, and lead and rear uppercuts) thrown by trained and untrained punchers. 2. To determine the validity of three commercially available punch trackers (Corner, Hykso, and StrikeTec) for monitoring punch velocity and force during rear straight punches, rear hooks, and rear uppercuts performed at lower and higher intensities by trained and untrained punchers. 3. To determine the reliability and load-velocity profiles of three different landmine punch throw variations (seated without trunk rotation [LPwo], seated with trunk rotation [LPw], and standing whole body [LP]) with different loads (20.0 kg, 22.5 kg, and 25.0 kg), all with the dominant (DH) and non-dominant hand (NH). Methods: Due to three independent studies in this dissertation, the methods are divided into three sections, each connected to the objectives mentioned above: 1. Ten trained and 11 untrained punchers different punch combinations, and punch trackers data were compared to data from video...

Title: The objectivization of evaluation of the dynamics of self-defense instruments Introduction: Strikes by the upper limb are key tools for the self-defense system. So far, mechanical properties have not been evaluated for a wider group of strikes without protective equipment with applications in training, injury risk assessment, forensic biomechanics and medical law. Objectives: The aim of this work is to compile and objectify the evaluation of the dynamics of a wider group of strikes by the upper limb by specifying the size of the contact area and describing the damping properties of the foam of the detection apparatus. The aim is to evaluate the impact force, the probability of exceeding the bone tissue fracture threshold, the impulse, the size of the impact surfaces and the pressure for three impact techniques, both sexes and two experience levels. Methods: The work consists of three projects. Two quasi-experiments were completed by 169 probands, men and women, experience levels beginner, advanced (n = 169, height 177.8±9.0; weight 81.6±17.8; age 27.3±8.1) within one period. Probands were measured on two devices (Kistler, Podokam), where the time, impact force of the blow was recorded and three segments of the upper limb were photographed. Probands performed 3 striking techniques, a total of...

Effect of disciplinary specialization on the body mass distribution in the body of karateka
Zdobinský, Adam ; Pavelka, Radim (advisor) ; Reguli, Zdenko (referee)
Title: Effect of disciplinary specialization on the body mass distribution in the body of karateka Aim of work: The main aim this thesis os to discover whether the disciplinary specialization effects the body mass distribution on limbs of karateka. Methods: The thesis has an empiric and theorethic character. Data collection is processed by dynamometry, measurement of limb circuits and body mas analyzation by Tanita MC-980. Data evaluation is processed by basic statistic methods. Keywords: Karate, kata, kumite, dynamometry, symetry
