Changes in biomechanical parameters of the running stride during model training of a special pace 800m runner (in the preparatory and competition period)
Petrásková, Veronika ; Hojka, Vladimír (advisor) ; Feher, Jan (referee)
Title: Changes in biomechanical parameters of the running stride during model training of a special pace 800 m runner (in the preparatory and competition period) Objectives: The aim of this pilot study was to determine the dynamics of changes in selected biomechanical parameters and then to compare these changes in probands over a 2- month period based on baseline and outcome measurements. Methods: The measurements were performed on three probands, each proband representing a different type of runner (novice athlete, recreational athlete, performance athlete in the national under-23 team). Qualitative analyses with the Optojump device were used. The research was carried out in a pressurized hall in Strahov on an indoor 200 m track in two measurements. The first measurement represented the end of the preparation period and the second the competition period. The probands completed the so-called model training (300 m and 200 m) at a special pace with a one-minute break between sections. During the selected sections, biomechanical parameters were collected by Optojump equipment on an indoor 200 m track in 10 m corridors. Results: Proband 1 improved by 3.1 s over 300 m and by 2.1 s over 200 m in the output measurements of the model training. This improvement was reflected in a 0.006 s reduction in...

EMG analysis of the hip joint muscles in runners with iliotibial band syndrome
Procházková, Kateřina ; Nováková, Tereza (advisor) ; Žáková, Lenka (referee)
Title: EMG analysis of the hip joint muscles in runners with iliotibial band syndrome Objectives: The main aim of this thesis was to analyse bilateral difference in activity of the hip joint muscles in runners with iliotibial band syndrome. Second aim was also to determine the role of limb dominance in the formation of ITBS. Methods: Twenty-two runners with ITBS underwent EMG muscle testing. M. tensor fasciae latae, m. gluteus medius and m. gluteus maximus were tested during dynamic movements on one lower limb. These included squat, vertical jump and jump off the box. Results were expressed as a percentage of maximal voluntary isometric contraction (MVIC). Results: The results indicate a significantly higher activity of the gluteus maximus muscle on the affected lower limb (41.55%) compared to the unaffected (27.50%) during the box jump exercise (p= 0.00926). The m. tensor fasciae latae and m. gluteus medius muscles did not show significant bilateral asymmetrical activity. The results did not show a connection between the dominant lower limb and the side of the ITBS formation. Keywords: iliotibial band syndrome, ITBS, running biomechanics, electromyography, EMG, m. gluteus medius, m. tensor fasciae latae, m. gluteus maximus, lateral knee pain, tractus iliotibialis, long distance runners

The view of specialised literature on barefoot running and running in traditional shoes (comparative literature review)
Holečková, Klára ; Kaplan, Aleš (advisor) ; Vindušková, Jitka (referee)
Title: The view of specialised literature on barefoot running and running in traditional shoes (comparative literature review) Objectives: The main objective of the presented thesis was to find, read and categorise available Czech and especially foreign literature about the barefoot running topic. Other objective was to create a systematic comparative review of reclaimed information, in which the opinions of authors are compared. Due to formulated objectives, the following task of the thesis was defined. To offer readers a systematic review and describe the presented topic. Methods: The presented bachelor thesis is a comparative literature review, especially foreign- language literature. The keywords were first stated in the English language. After that, they were used for searching for information in science databases. Similarly, the keywords were stated and used for searching information in the Czech language. Due to the systematisation of the terms, it was necessary to gain enough information about the presented topic, which were categorised in the pre-determined chapters. Results: The presented literature review was created from 29 foreign science studies and 11 book publications (5 of them were Czech authors). Some of the authors' opinions on the studied issue were in agreement. For example,...

Analysis of technique and efficiency of running using Nike Air Zoom Alphafly shoes
Veselý, Vít ; Kovářová, Lenka (advisor) ; Červinka, Pavel (referee)
Title: Analysis of running technique and efficiency when using Nike Air Zoom Alphafly shoes. Objectives: The main goal is to identify possible changes in selected physiological parameters and biomechanics of running when using Nike Air Zoom Alphafly shoes compared to standard running shoes. Methods: A 3D treadmill (H/P Cosmos Gaitway II S, Germany) was used in the analysis of running biomechanics. For the analysis of physiological parameters, the Metalyzer device was used within the spiroergometric examination of the run. The Borg scale was used to analyze the subjective assessment of the load. A paired T-test of Excel software was used to process the results. Results: The results of the work partially show a change in the biomechanics of running. A statistically significant difference was recorded at all speeds (15 km/h, 18 km/h, 21 km/h) in loading rate (p15 = 0,003; p18 = 0,000; p21 = 0,001) and time to impact peak (p15 = 0,017; p18 = 0,022; p21 = 0,003). At a speed of 15 km/h, an additional difference in running cadence (p = 0,044) was noted. The results show a statistically significant change in the economics of running all measured parameters, in oxygen intake converted to kilograms of weight (p = 0,003), minute ventilation (p = 0,000), respiratory rate (p = 0,000), respiratory coefficient (p...

Comparison of postural stabilization of athletes and trail runners with postural somatoosilography
Čajka, Vladimír ; Rašev, Eugen (advisor) ; Véle, František (referee)
Title: Comparison of postural stabilization of athletes and trail runners with postural somatoosilography. Objectives: The main aim of this study is comparison of postural stability of athletes (track runners) and trail runners. We want to determine, if run in the field can affect positive postural stabilization. Methods: In our thesis we used a method of analysis and a method of comparison. Analysis is performed with postural somatooscilography (PSOG). This method contains postural provocation test on Posturomed. Oscilation of this platform is shooted in program Microswing 5.0. Then these dates are evaluated in program Posturomed Commander. We compared these dates with statistical methods and box plots in program Statistica 10 and Microsoft Excel 2007. Results: We found out when we compared 17 trail runners and 11 track runners that trail runners reached better postural stability. Trail runners had better postural stability in the first measurement and also had better results in comparison of three measurements. Track runners achieved the best results in the third measurement and trail runners had the best results of postural stabilization in the second measurement. Keywords: postural stabilization, biomechanics of running, Posturomed, postural somatooscilography
