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...

Atypical Pronation of the Sub-Talar Joint: Its Implications on the Lower Limb.
Frank, Danielle ; Pánek, David (advisor) ; Satrapová, Lenka (referee)
Title Atypical Pronation of the Sub-Talar Joint: Its Implications on the Lower Limb Background Atypical pronation of the sub-talar joint, or overpronation of the foot, as it is more commonly known, is a current subtopic in foot and lower limb-related biomechanical issues. Typical pronation is a tri-planar movement that involves eversion of the hindfoot, combined with abduction and dorsiflexion of the forefoot. Atypical pronation is recognized when this motion is excessive, and may be determined by the extent and duration to which this occurs according to the rhythmic timing during the gait pattern. It is a mechanical problem of the foot that primarily results from a subluxation or shift of the sub-talar joint and bones of the mid- and hind-foot. As a common finding in the general population, especially in those with flexible flat feet, atypical pronation may result chronically in a displacement of the bones and joints of the lower limb. Research has stated that excessive pronation of the ankle-foot complex may cause change in position of certain bones in the lower limb. This is believed to occur through an interaction between foot and pelvis through a kinetic chain mechanism. Furthermore, it has been stated that atypical pronation may affect weight transfer of the lower limb during gait that may...
