Technique of ground contact of the Czech elite female runners
Petrikovičová, Markéta ; Červinka, Pavel (advisor) ; Feher, Jan (referee)
Title: Foot strikes technique of elite Czech female runners. Aims: The main aim of this thesis was to analyse the pedalling of elite Czech female runners at the beginning and at the end of the main part of the training unit. Subsequently, to compare the results with the literature on the subject, to answer the research questions and to formulate conclusions. Methods of work: Kinematic analysis was used to create this work. Considering the objectives of the thesis, a qualitative method was chosen with subsequent recording of key moments of the foot strike technique in a recording sheet. Results: The fatigue during the main part of the training unit of the Czech elite female runners did not affect their pedaling technique. Female athletes who specialize in middle distances usually adopted a forefoot or midfoot landing strategy, while long- distance runners are characterized by a heel strike. Key words: ground contact, analysis, elite female runners, pronation, supination

The influence of footwear on biomechanics of foot strike of recreational runners
Pekárková, Klára ; Pokorný, Jan (advisor) ; Illinger, Vojtěch (referee)
The bachelor's thesis deals with the issue of hyperpronation syndrome of recreational runners, whose frequency is 15-20 % in the running community. The aim of this work is to evaluate the effect of footwear on the degree of hyperpronation and related parameters of the running step. The theoretical part of the thesis deals with the kinesiology of the foot with emphasis on the functional issues of hyperpronation, biomechanics of the running step and the connection of the running step with running injuries. In the practical part, running in footwear and running barefoot are compared using images from 2D kinematic analysis and data from the Zebris FDM-T System. The clinical examination of the modified Trendelenburg and Véle test is also evaluated. The monitored group consists of 13 recreational runners (7 men and 6 women, average age 26,5 years). The measured parameters are the degree of hyperpronation (objectified by the eversion of the heel and the progressive angle of the foot), the loading time of the functional sections of the foot, the inclination angle of the foot, the frequency and the length of the stride. The results of the thesis show that the change in afferentation and the associated change in the biomechanics of foot strike in footwear have a statistically significant effect on the degree...

The Influence of Footwear on Running Style and Injuries
Kolovecká, Michaela ; Hora, Martin (advisor) ; Soumar, Libor (referee)
In recent years running has become a very popular sport. Therefore it is nowadays often discussed whether it is shod running or barefoot running that is better. The aim of this thesis is to provide a summary of scientific pieces of knowledge on the effect of footwear on running style and related injuries. The introduction chapter describes the basics of running techniques and progressive development of running styles in relation to the development of running footwear. The following chapters describe in detail results of studies about the impact of footwear on kinematics, foot strike pattern and ground reaction forces, muscular activity and the running economy. Other chapters deal with the influence of footwear as a source of running related injuries while the most common running injuries are subsequently analysed. The last part is a practical section. It is a questionnaire study in which in total 93 runners participated. The conclusion summarizes the essential pieces of knowledge on the topic of footwear influence on running style and related injuries which are compared with the results collected in the questionnaire.
