Biomechanical aspect of speed canoe technic
Štryncl, Radim ; Šifta, Petr (advisor) ; Šorfová, Monika (referee) ; Cirkl, David (referee)
Name of the thesis: Biomechanical aspects of speed canoeing techniques in the context of asymmetric loading of the postural system Aim of the thesis: The main aim of the work was, based on theoretical knowledge and own empirical research, to analyze the biomechanical aspects of the technique of riding a C1 speed canoe in the context of asymmetric loading of the postural system . . Solution method: Based on the knowledge of functional anatomy and with the use of analyzes of the real riding of the top athletes (N = 12), the kinesiological aspects of riding the C1 speed canoe were investigated in the preliminary research. Biomechanical aspects of paddling were further investigated using 3D kinematic analysis (N = 9). Influence of long-term training efforts on differences in muscle cross-sections mm. iliopsoas a mm. quadratus lumborum on both sides of the body was examined by magnetic resonance imaging (N = 5). The muscle sections were performed in the transverse plane at the level of L 3, L 4. The studies were conceived as pilot due to their time, organizational and financial demands. Results: Riding a C1 speed canoe is a locomotively complex movement pattern during which the postural system is exposed to two types of asymmetric loads. Both are related to the geometry of motion. First of all, it is a...

Effect of asymmetric load on the stereotype of running.
Holíková, Dana ; Pánek, David (advisor) ; Satrapová, Lenka (referee)
Title: Effect of asymmetric load on the stereotype of running. Objectives: The aim of this experimental work is to evaluace the electromyographic activity of selected muscles when running without load and with load on the treadmill, and the co- current assessment of the impact of asymmetric load on the lateral weight distribution. Methods: Six recreational runners underwent the experiment during which we monitored electrical activity of m. deltoideus pars anterior, m. trapezius pars ascendes et descendens, lumbar paraspinal muscles, m. gastrocnemius lateralis and m. tibialis anterior while running without load and with load on the periphery of the upper right extremity. For the experiment a motor treadmill at a constant speed of 10 km/h was used and a 0,5 l PET bottle completely filled with water was applied as the load. Changes of lateral weight distribution were assessed having investigated stance on two scales. The measured values were statistically evaluated. Results: Within the group of all the probands it was proved that there existed an impact on normalized average amplitude of EMG signal at left-oriented m. gastrocnemius lateralis. The hypothesis of the influence of asymmetric load on the lateral weight distribution was not demonstrated. Keywords: endurance running, surface...
