Title: Assessment of the significance of falling techniques through the measurement of force and impact velocity during sideways falls. Goals: The aim of this study is to compare biomechanical parameters of controlled and uncontrolled breakfalls using a force plate, such as force impulse, maximum force and time. Methods: Two top judo competitors with at least 10 years of judo training experience were purposively selected for the study. One of the selection criteria was the technical level that reaches at least 1st kyu (brown belt) which guarantees the technical maturity of the individuals. A biomechanical force plate from Kistler was used to obtain data which allows real-time measurement of force and impact velocity. The data were evaluated using BioWare software. Furthermore, descriptive analysis of the results was performed in Microsoft Excel. Results: The results of this study show that a controlled (controlled) sideways fall performed with the technique used in judo generally exhibits a smaller average maximum impact force, longer duration and higher average force impulse than an uncontrolled (uncontrolled) sideways fall. Keywords: Judo, breakfalls, fall biomechanics, force plate, maximum force, force impulse, fall velocity, controlled fall, uncontrolled fall.

Falling of elderly population
Islami, Timur ; Šorfová, Monika (advisor) ; Nováková, Pavlína (referee)
Title: Falls in the eldery Objectives: The aim of this diploma thesis is to analyze and classify knowlage about falls in the eldery during usual daily activities with focus on prevencion and detection of falls by useing wearable and non wearable systems for detecting falls in the eldery. Methods: This diploma thesis is wrote with the metod of literary research through professional literature, books and articles in both Czech and English was used in the work. To meet the objectives that have been provided were selected examples that helped analyze and clarify the issue of falls in eldery. Results: The sources of professional literature have shown that the falls in the eldery are very serious issue of society. At the same time, it is important to be aware of their possible health and economic impacts, as well as how to prevent them. The correct use of fixation shoes has been shown to reduce the risk of fall. Many fall detection devices are able to call for timely help. Last but not least, knowlage of this issue could help to improve and innovate the fall detecion and prevention systems. Keywords: falls in eldery, senior immobilization, biomechanics of falls, detection and prevention of senior falls, osteoporosis, senior bone aging, senior cartilage aging, biomechanics of senior walking, walking...
