The pressure distribution on the soles of feet in the medium parallel turn in the alpine and the telemark technique of downhill skiing
Svobodová, Renata ; Jindra, Matouš (advisor) ; Bačáková, Radka (referee)
Title: The pressure distribution on the soles of feet in the medium parallel turn in the alpine and the telemark technique of downhill skiing Objectives: The aim of this thesis is to compare the pressure distribution on the soles of feet in the medium parallel turn in the alpine and the telemark technique of downhill skiing. Methods: For the analysis of pressure distribution on the soles of feet in downhill skiing was used the pressure measurement system Pedar-X, which works for monitoring of plantar pressure (kPa) moreover. The pressure distribution measuring on the soles of feet was taking place in prepared track of the ski slope in two ways. The first one was the telemark technique and the second one was the alpine technique. For the evaluating and the processing of the results was selected in the right and in the left turn of each testing person in approximately the same part of the track. Results: The results of pressure distribution in the alpine and the telemark position turn have shown the significantly important difference in the intraindividual comparison in every technique. The significantly important difference was detected also in the interindividual comparison in both techniques each other. Keywords: downhill skiing, telemark, Pedar-X, pressure distribution

The influence of the surface load distribution of the foot during dynamic movement in tennis
Šebíková, Linda ; Maršáková, Kateřina (advisor) ; Kubový, Petr (referee)
Title: The influence of the surface load distribution of the foot during dynamic movement in tennis Objectives: The aim of this work is to determine whether there is a change in the force load in the area of the sole of the foot during the forehand strike phase in an open position depending on the type of playing surface. Methods: The research was attended by 10 level I tennis players of ranging from the age of 17 to 28. Each of the players has played tennis for at least two years, train 2 - 3 times a week and has no limb injury in the past 12 months. Using the Pedar-X instrument, changes in the force of the plantar load during the forhend strike phase on clay and Casali surfaces were measured. To evaluate these changes, the contact forces [N] (vertical reaction forces) were measured. First, an intra-individual foot impact assessment on the heel region and forefoot on the clay and Casali surface were performed using graphs of temporal force averages. Secondly, an inter-individual evaluation of the maximum force values in the region of the heel, midfoot, forefoot, hallux and lesser toes and whole feet of the foot was performed using the paired t-test statistical method. Results: The results of the work show that the different surfaces influence the size of the load as well as its plantar...
