Tulachová, Johana ; Busta, Jan (advisor) ; Bílý, Milan (referee)
Title of project: Comparison of somatic parameters of female canoe sprint and canoe slalom competitors Objectives of the work: The aim of this work is to compare the anthropometric parameters (body structure and body composition) of sprint canoe and canoe slalom female competitors. Methods of data processing: Anthropometric measurement was carried out by Riegerová, Přidalová, Ulbrichová (2006) and all parameters were all in accordance with the ISAK methodology used in the study by Ridge et al. (2007). A Harpenden-type caliper was used to measure skinfolds. Somatotypes were determined according to the methodology of Carter & Heath (1990). A bioimpedance scale (Tanita MC-980) was used for body composition analysis. The data were subsequently analyzed using descriptive (mean, standard deviation, median, minimum and maximum value, %) and exploratory statistics to assess statistical (T- test, p<0.05) and substantive (Cohen's d, d>0.8 ) of the significance of the difference between female in canoe sprint and canoe slalom. Results: In the compared groups, significant statistical differences were recorded in the circumferences of the biceps (p=0.00, d=1.43), forearms (p=0.04) and thighs (p=0.00, d=1.87). Sprint female canoeists and kayakers, on average, have a higher body weight by almost 4 kg, also a...

Foukal, Pavel ; Bílý, Milan (advisor) ; Busta, Jan (referee)
Title: Description of physical characteristics of the C1 forward stroke in selected elite canoe slalom athletes Objectives: The aim of this study was to describe the physical characteristics of a forward stroke in C1 using strain gauge measurement among selected elite canoe slalom athletes during flatwater paddling, and to organize the obtained results into a clear format. Methods: We used a single-axis foil strain gauge attached to each tested person's paddle and an accelerometer (G-link 200) positioned at the front of the boat to obtain the data. Everything was connected to a data acquisition unit (V-link 200). We processed the data using the Sensor Connect software developed by Lord Microstrain. Results: We have been able to describe the basic physical characteristics of the forward stroke on the dominant and non-dominant side as well as the cross stroke. It turns out that a greater force applied in the stroke does not necessarily lead to a faster resultant time for a given segment. Similarly, a higher frequency of strokes does not automatically lead to faster and better times. Boat speed is not dominantly determined by any of the physical indicators of the stroke cycle studied, but is probably determined by a combination of them, related to other factors such as the shape of the boat, the...

Bezděková, Hana ; Busta, Jan (advisor) ; Bačáková, Radka (referee)
Author: Bc. Hana Bezděková Title: The Effect of Proprioceptive Neuromuscular Facilitation to Cervical Spine Posture in Road Cyclists Objectives: The aim of this diploma thesis is to assess the effect of 6 weeks proprioceptive neuromuscular facilitation theraphy on posture of the cervical spine in road cyclists. Methods: This is a quaziexperimental study with general noninvasive examination. Photogammetry was used for evaluation of posture of the cervical spine and craniocervical flexion test was used to assess strength in deep neck flexors. The group that was examined consisted of 8 men and 2 women. Statistical analysis was performed using Shapiro-Wilk test, coupled t-test and regression. The siginificance level was set to α = 0,05. Cohen's d test was used to verify material significance. Results: There was no statistical and effect size significance found in input and output difference of craniovertebral angle in the experimental group after 6 weeks of PNF exercises. On the other hand, we have proven the statistical and effect size significance in strenght of deep cervical flexors before and after PNF treatment. Road cyclists are also, proportionally to time spent road cycling, more vulnerable to forward head posture. Keywords: proprioceptive neuromuscular facilitation, road cyclists, cervical spine

Title: Comparison of the results of aerobic exercise testing while kayak paddling whith crank ergometry of upper limbs. Aims: The aim of the study was to determine the relationship between the results of aerobic execise diagnostics of 6 elite kayakers (white water slalom) when paddling of flat water with crank ergometry of upper limbs. The results obtained when paddling on flat water were also compared with results obtained when paddling in the pool with counter (bachelor thesis). Based on the results we wanted to answer the question about the possible use specific forms of stress diagnosis (spiroergometry) in routine practice of training proces. Methods: We used standardized laboratory spiroergomtry stress test at crank ergometry of upper limbs and spiroergometry stress test when paddling on flat water of the same protocol. To obtain the functional values of physiological indicators in both test we used mobile spiroergometry equipment Cortex Metamax 3B and sporttester Polar. Feedback of probands were identified based on suervey with closed questions. Results: Testing kayakers reached when paddling on flat water the average functional values: heart rate (HR) 188,5 (±8,77) beats per minute, maximal oxygen uptake (VO2max.) 56 ml.kg.min-1 (±6.31); maximum ventilation (VMAX.) 127.31 l.min-1 (±15.16);...

The relationship between selected conditional abilities and performance in white water slalom (category C1).
Busta, Jan ; Suchý, Jiří (advisor) ; Lehnert, Michal (referee) ; Bielik, Viktor (referee)
The aim of the study was to identify the relationship between selected fitness skills and the performance demonstrated in nomination races (NR) to the Czech Republic national team (NT) and for the Olympic Games. At the same time, we wanted to determine the optimal level of conditioning assumptions and define a model single-canoe sportsman. We were also searching to determine the differences between Senior NT and Junior NT. The research sample (n=17) of the Czech highest competitions series (Czech Cup) participated in testing to determine level of strength, endurance and partly speed assumptions. There were also measured anthropometric parameters (body dimensions and composition) in detail. Testing took place only 5 weeks before NR. The condition indicators were subsequently correlated with the NR performance. For indicators for which significant and at least moderate correlation were found, the possibility of performance prediction was also found. The highest correlations with performance were found in case of on-water sprints: 20m (rs=0,65), 40m (rs=0,86, resp. rs=0,62), 80m (rs=0,58) and 200m (rs=0,795). The on-water sprints are the only indicators, which could be possibly used for the NR performance prediction. In multiple regression of the 2 40m and 1 200m sprints was found high determination...
