Title: Specifics of sport training of canoe marathon athletes Objectives: The main goal of this work is to characterize the specifics of sports training in canoe marathon courses. Methods: In our work we used the method of analysis and the method of questionnaire survey. We used the questionnaire survey method to obtain the results. The method of analysis was applied in the analysis of the main specifics of marathon training. The questions in the questionnaire survey are open, semi-closed and closed. Results: The main specifics of sport training of canoe marathon athletes that are based on the results from this study include riding in a group and on a wave, changes of pace with high acceleration or deceleration and consequently the ability to recover during the race, boat runs, turnarounds, certain tactics, high mileage and hours spent training. 91.9 % of marathon paddlers train more than 13 hours and 44.6 % even more than 16 hours per week in the preparation period. In the competition period, 74.3 % of athletes train 13 or more per week. In one annual macrocycle, 85.1 % of athletes paddle more than 3000 km, 45.9 % of athletes get over 4000 km and 21.6 % even cross the 5000 km mark. It was found that 55.4 % of respondents engage in less than 3 hours of weight training per week and 40.5 % include...

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.

Comparison of a succes rate of sprint canoeists in junior and senior categories based on their international results.
Krpatová, Lucie ; Bílý, Milan (advisor) ; Boháč, Jan (referee)
Title: Comparison of a succes rate of sprint canoeists in junior and senior categories based on their international results. Aims: The aim of this work is to find out the potential future success of Czech junior medal winners in the adult category. Methods: We have chosen the method of data analysis to describe the course of a given sport career. The data was obtained by processing the results of the European Junior and Under 23 Championships from the period between 1996 and 2019, the World Junior and Under 23 Championships from the period between 1996 and 2019, the European Championship from the period between 1999 and 2019, the World Championship 1999 - 2019 and the Olympic Games 2000, 2004, 2008, 2012 and 2016. Results: The analysis of the results suggests that the training system and financial support dedicated to flatwater racing introduced in 2006 helped to significantly improve the success of Czech junior athletes at international events in all examined categories (men kayakers, canoeists, women kayakers). The analysis further showed that the success of the examined groups within senior categories has different tendencies. While the group of kayakers shows a small percentage of career termination under the age of 23 (23,5 %) and a relatively high success rate of winning medals in...

Evaluation of postural stability of sprint kayak athletes.
Hájek, Šimon ; Pavlů, Dagmar (advisor) ; Opatrná Novotná, Irena (referee)
Title: Evaluation of postural stability of sprint kayak athletes. Objectives: The aim of this thesis is to compare the level of thy dynamic postural stability of sprint kayakers with healthy population, which don't do any sport regularly with computerized posturography on the NeuroCom SMART EquiTest device. Methods: It is quantitative cross-sectional study. 24 sprint kayakers (experimental group) participated in this study and 40 individuals (control group), which don't do any sport on competitive level. The dynamic postural stability was evaluated with computerized posturography on the NeuroCom SMART EquiTest device in the Laboratory of Applied Kinesiology at the Department of Physiotherapy in Charles University Faculty of Physical Education and Sport. Every participant was tested once in all seven tests - - Sensory Organization Test, Motor Control Test, Adaptation Test, Limits of Stability, Rythmic Weight Shift, Weight Bearing Squat, Unilateral Stance. Data was recorded and processed by the NeuroCom Balance Manager Software and then converted into Microsoft Excel 365 programe. Data was statistically analysed by Shapiro - Wilk test, Mann - Whitney test, Pair t - test and Cohen's d. Results: Due to low number of statistically significant differences, we couldn't say that sprint kayakers have better...

Title: Determining the relationship of spiroergometric testing on the canoe ergometer and in canoe sprint by elite competitors. Objectives: The aim of the study was to determine the relationship between the results of aerobic exercise diagnostics in canoeing and on the canoe ergometer by Czech national team members in canoe sprint. Methods: Within our study we tried to find out and compare the physiological response of two functional load exercise diagnostics in canoeing and on the canoe ergometer. To obtain the functional values of physiological indicators in both tests we used mobile spiroergometric equipment Cortex Metamax 3B and sport tester Polar RS 800. Results: Testing canoeists paddling on flat water reached the following average functional values: maximal heart rate (HR) 181 min-1 (±3,9), maximal values of blood lactate (LA) 8,04 ml.l-1 (±1,6), maximal oxygen consumption (VO2max) 51,6 ml.kg.min-1 (±6,7), maximal ventilation (VEmax) 140,2 l.min-1 (±26,5), respiratory rate (RR) 51 min-1 (±3,7), metabolic load (Rmax) 1,14 (±0,07) and anaerobic threshold (ANT) 166 (±7,2). When paddling the canoe ergometer, they reached the average maximum values: maximal heart rate (HR) 181 min-1 (±5,2), maximal values of blood lactate (LA) 9,1 mmol.l-1 (±2,9), maximal oxygen consumption (VO2max) 56,4...

Mára, Petr ; Bílý, Milan (advisor) ; Kovářová, Lenka (referee)
Title: Determining the relationship of spiroergometric examination of sprint canoe competitors while paddling and at the arm crank ergometer. Objectives: The aim of this thesis was to investigate the relationship between functional indicators of aerobic exercise diagnostics on sprint canoe and at the arm crank ergometr. Methods: To obtain the data, we used a standardized stress test for arm crank ergometr. To to measure flatwater canoists while paddling, the spiroergonomic examination with the same stress protocol was used.The devices used during both experiments were sporttester Polar RS 800 and Cortex Metamax 3B device. To detect the functional relationships of measured values the correlation analysis was used.The degree of dependence was determined by Pearson correlation coefficient. Results: Total average difference between the values measured at arm crank ergometr and while paddling at sprint canoe was 2,13%. Correlation analysis showed a strong dependence in 4 of the 7 monitored fiction pointers: VO2 (r = 0,873), VO2max (r = 0,972), tidal volume (r = 0,775) and pulmonary ventilation (r = 0,786). As for the three remaining indicators; respiratory rate (r = -0,023), lactic acid (r = -0,08) and heart rate (r = -0,275) there was no statistically significant difference. Key words: Crank...
