Frontzová, Kamila ; Hojka, Vladimír (advisor) ; Vostatková, Pavlína (referee)
Title: Comparison of kinematic and dynamic characteristics of the running stride in barefoot running, minimalist shoes, spiked shoes and running shoes Objectives: The goal of this study is to determine how selected kinematic and dynamic characteristics of the running stride change with different types of footwear (shoes, spiked shoes, minimalist shoes) or when running barefoot. Methods: The measurements were conducted on 21 participants (active athletes competing in athletic disciplines for at least four years, capable of running in track spikes). A biomechanical analysis was performed using dynamometric plates and the Optojump Next optical device. The research was conducted on a long jump runway at the Faculty of Physical Education and Sport of Charles University, with each participant running a prepared 30-meter track 8-10 times at 80 % of their maximum speed. Statistical analysis was performed using the magnitude-based inference method. Results: Step frequency increased when running barefoot (shoes: 3.89 ± 0.23 steps/s, minimalist shoes: 3.90 ± 0.18 steps/s, track spikes: 3.91 ± 0.21 steps/s, barefoot: 3.94 ± 0.22 steps/s), step length shortened when running barefoot (shoes: 199.3 ± 7.5 cm, minimalist shoes: 200.1 ± 6.3 cm, track spikes: 199.7 ± 6.8 cm, barefoot: 198.8 ± 6.7 cm), and the flight...

The influence of running shoes on leg and pelvis kinematics during the stance phase of run
Novák, Čestmír ; Malá, Jitka (advisor) ; Kaplan, Aleš (referee)
Title: The influence of running shoes on leg and pelvis kinematics during the stance phase of run Objectives: The main objective of this thesis is to detect whether there exists a connection between the type of shoes used and changes in pelvis and legs kinematics in sagittal plane while running. Methology: For a purpose of the thesis research 12 active sportsmen (6 men and 6 women) participated in lab tests. Each of them was running on a tread mill for three time sequences - each counting 20 seconds - with changes in conditions applied as follows: barefoot run, minimalistic shod run, classic shod run. The 3D analysis was analysed using the Qualisys system (200 Hz). Data analytics was executed using the Qualisys Track Manager programme, where a comparative method was applied. Further statistical procedures ANOVA a Tukey test were performed in a programme called OriginPro 8. Key findings: The executed lab tests proved influence of running shoes on legs and pelvis kinematics during a stance phase of run. The main changes in kinematics were found in an ancle during touchdown, where the angle significantly increased while running barefoot rather than classic shod running. An analysis of pelvis kinematics parameters has proven that there are no changes in pelvis movements while running in different types...

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.

Running training of triathlete
Řehák, Martin ; Kaplan, Aleš (advisor) ; Červinka, Pavel (referee)
Title: Running training of triathlete Student: Martin Řehák Supervisor: PhDr. Aleš Kaplan, Ph.D. Aims: The aim of this bachelor thesis is to study the professional publications, training documents, methodological texts and subsequent preparation of scoping study about the topic running training of triathlete. Methodology: The creation of this bachelor thesis was used scoping study, which was created based on analysis of the available professional literature, training documents and articles from many information sources including scientific electronic bibliographic databases. Results: Study more than fourty different literary sources and creating this final work with shape of scoping study is a comprehensive text, summarizing the scattered information on the topic running training of triathlete, from witch it follows that in a methodical concept do not differ a preview of the running training by the authors of older publications and contenporary authors, who profess modern aproaches. Also showed that inexpert and free accessible training plans from internet sources are useless for use in the practice training of amateur athletes. Key words: Triathlon, running, running training, technique of running, diagnostics analysis of running, triathlon training, sport training, performance diagnostics, running...

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.

Research on purchasing behaviour of runners in choosing running shoes
Němcová, Lenka ; Voráček, Josef (advisor) ; Šíma, Jan (referee)
Title: Research on purchasing behaviour of runners in choosing running shoes Objectives: The main objective of this thesis is to identify and describe purchasing behaviour of runners in all the phases of choosing running shoes. Purchasing behaviour is therefore investigated in the phase before purchasing running shoes, when purchasing running shoes and after that as well. Methods: An online survey method through a specialized website Click4survey has been used to obtain the resulting data. A questionnaire consisting of 26 questions, which helped to determine the results and to achieve the objectives of this thesis, was created on this website. Results: Purchasing behavior of runners in choosing running shoes was described based on information obtained from the online questionnaire. Runners collect information mostly from the internet, they highlight the comfort of the running shoes and they belong rather to satisfied and loyal customers. The ascertained values have brought also other interesting findings and also have brought a new perspective on the issue of purchasing behavior and decision-making process of a very specific customer group, the runners. Key words: running shoes, runners, purchasing behaviour, marketing research
