Utilizing wearable devices for digitizing the 3D motion of an athlete during strength training
Vitková, Emma ; Holcman, Vladimír (referee) ; Tofel, Pavel (advisor)
In the field of wearable devices aimed at monitoring physical activity and health, technological advances have provided new opportunities for the analysis of sport and physical training. With the help of Movella DOT inertial sensors, it was possible to obtain the position from the acceleration and then digitize the movement of the athlete performing the selected exercises of shoulder press, squat and deadlift. The obtained positionof the selected sensor on the wrist was compared with the position of the reference system from the company Qualisys with the help of a marker placed on the given sensor. After calculating the absolute distance of the maximum and minimum distance for both devices, it was found that after applying the statistical test, there are no significant statistical differences between the calculated distances for both devices. Next, the obtained displacement was applied to the model, which demonstrated digitized movement in 3D space. However, it is obvious that the number of five used sensors for digitizing the whole body is not sufficient, which led to slight differences between digital and real movement.

Development of a mobile application for fitness activities for the Android OS
VESELÝ, František
The objective of this bachelor thesis is to create a mobile application for the fitness activities which is using sensors in mobile phones. The application is using accelerometer and proximity sensor for different activities. It is about push ups, pull ups, squats and sit ups. The application also can show a graph with historical data of each fitness activity. Finally, the application is published and free to download in the Google Play online store. The theoretical part presents Android operating system, description of the Android Studio and java language. The practical part of this thesis contains description of the development of the mobile application, description of the creation of the user interface and a connection with the logic of the application. Then the thesis includes description of a work with data, the connection with sensors, a process of publishing the application and a summary of reviews from the users.

Motion analysis of lower extremity during squatting.
Varga, Pavel ; Vilímek, Miloslav (advisor) ; Jelen, Karel (referee)
Title: Motion analysis of lower extermity during squatting Aims: The aim of the thesis is to compare the squat without and with external load in a group of people who work under professional guidance and have experience with this movement, contrary to the people of the common population. Another objective will be the compasion this movement among men and women of the common population. In the theoretical part, the main objective is to describe the basic characteristic of the squat, describe the kinesiological and biomechanical findings and the risks of this movement on the locomotive apparatus. The experimental part will focus on the observation of the determined kinematic parameters of squats and their comparison in the mentioned set of persons. The results of the work should clarify the possible side effects of the squat. Methods: Kinematic analysis will be performed using Qualisys instrumentation. Infrared cameras accurately record and further perform a motion action through passive or active reflection markers. Data from the device will be processed in Microsoft Office Excel software and further evaluated statistically. Results: The results show that there are significant variations in the performance of the movement among groups of men actively engaged in squats under professional guidance and...
