Influence of defferent kinds of running shoes on stability and risk of injury in long - distance runners
Krchová, Zuzana ; Čakrt, Ondřej (advisor) ; Doubková, Lucie (referee)
The main problems concerning birth of running injuries is their unclear ethiopathogenesis and high frequency. Injuries are often lined with forces affected on tread-down which have to be defused by running shoes. There are also opinions that currently used footwear can cause injuries on the contrary. This work explores impact of particular types of running shoes for influencing of stability. Methods: There are compared two groups of runners: minimalists and classic runners. Their stability is examined with help of posturography in three versions: barefoot, classic and minimalistic footwear. Thereafter there is analyzed relation among stability, used footwear, training usage and frequency of injuries. Results: Minimalists and classic runners have the same stability while they are barefoot. Usage of footwear does not cause significant deterioration of stability in any of groups. Nevertheless most of runners subjectively evaluate the variant of testing barefoot as the simplest. There is more frequent occurence of flat foot among classic runners in comparison with minimalists. Flat foot increases risk of formation injuries, on the contrary, regular compensation motion activity decreases this risk.

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.

The distribution of the strain and differences of muscle activity of the lower limb during stance phase in two basic running techniques
Šimon, Jan ; Slabý, Kryštof (advisor) ; Pokorný, Jan (referee)
This thesis is focused on the function of the foot during the running activity. There are two basic running techniques taken in account - the rearfoot strike and the forefoot strike. The aim is to compare the distribution of the strain during the stance phase of running cycle and its relation to the muscle activity of the lower limb. To analyze the muscle activity we use the technique of electromyography (EMG). To measure the pressure during the stance phase we used Pedar - X insoles from the Novel company. As a conclusion we aim to map the distribution of the strain of all particular parts of the lower limb. At the same time we are bringing the proposals for eliminating the overexertion while keeping the same training intensity and volumes.
