Davídek, Pavel ; Kobesová, Alena (advisor) ; Kolář, Pavel (referee) ; Matoulek, Martin (referee)
INTRODUCTION: The aim of this thesis is to identify the effect of trunk stabilization training based on Dynamic Neuromuscular Stabilization (DNS) on maximum kayak ergometer power output and reported self-disability in the shoulder girdle area. METHOD: Thirty flatwater kayakers of both genders (17 - 25 years old) were randomly divided into two groups. Crossover design was used for this study. Subjects in the experimental group (group A) integrated DNS exercises into standard flatwater training during the first phase. The control group (group B) conducted only common flat water training at the same time. After 6 weeks, the groups were switched. Then group B underwent the same DNS exercise with the same intensity and the same time. The intervention was the same for both phases and took 6 weeks. Group A performed only standard off-season training during the second phase. The maximum power output on kayak ergometer was measured three times (before study, after 6 weeks and after 12 weeks). Disabilities of the Arm, Shoulder and Hand (DASH) were analyzed at the same time. RESULTS: Initially, no significant differences in maximum power output on kayak ergometer and the DASH questionnaire score were identified between the groups. During the first phase the experimental group (group A) improved the maximum...

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...

Sobíšek, Martin ; Bílý, Milan (advisor) ; Hottmar, Pavel (referee)
Title: Comparison of stroke efficiency of sprint kayakers in K1 and K2 category Objectives: The aim of this work is to compare the performance of a single kayak (K1) and a double kayak (K2) using strain gauge testing and video recording. Methods: To obtain data, we used foil strain gauges attached to the paddle and two tri-axial accelerometers (G-link 200) placed at the front and rear of the boat. We used Lord Microstrain's Sensor Connect software to process the data. Results: The mean acquisition time on K1 was 0.305 ± 0.016 s and on K2 0.290 ± 0.018 s. The maximum acceleration on K2 was 0.84 m*s-2 less, the maximum force was 2.40 kg less. The maximum force for kayakers was recorded after 0.161 s on K1 and 0.153 s on K2 from the start of the stroke, whereas the maximum acceleration was after 0.113 ± 0.016 s on K1 and 0.104 ± 0.016 s on K2. The mean angle at the point of maximum force was 106 ± 9ř on K1 and 109 ± 7ř on K2, and at the point of maximum acceleration the athletes had the same angle on K1 and K2, only the standard deviation differed. Through this work, we found that the angle at maximum force can affect the time to reach maximum force from the start of the stroke. Key words: Canoe Sprint, difference between K1 and K2, strain gauge measurement, stroke graph, stroke comparison.

Title: Comparison of selected anthropometric parameters of competitive quadrathletes and racing kayakers. Objectives: The aim of this work is to assess the somatotype and anthropometric characteristics in elite athletes in marathon kayakers and quadrathletes. Methods: This research included the analysis and comparison of two groups of athletes. Using the Heath-Carter system of measurement, somatotypes were calculated using the computer formula, 'Somatotype - Calculation and Analysis'. Body composition was determined through the use of skinfold calipers SK in conjunction with noninvasive bioelectrical impedance analysis (BIA). Specifically, the Tanita 980 MS and BIA 2000 measurement units. Results: Two research samples were developed (speed kayakers as one, quadrathletes as the other), whose results (set average) were compared. On the basis of anthropometric data and calculations, it was found that both research samples corresponded in their somatotype category, ectomorphic mesomorph. According to this research, the speed kayakers (with a focus on marathon distances), are generally taller and heavier than the quadrathlete sample, yet had relatively less body fat. Keywords: Somatotype, body composition, BIA, skinfold, quadrathlon, flatwater kayaking
