1 Title: Convolutional neural networks and their application in object detection Author: Matej Hrinčár Department: Department of Theoretical Computer Science and Mathematical Logic Supervisor: doc. RNDr. Iveta Mrázová, CSc. Supervisor's e-mail address: Iveta.Mrazova@mff.cuni.cz Abstract: Nowadays, it has become popular to enhance live sport streams with an augmented reality like adding various statistics over the hockey players. To do so, players must be automatically detected first. This thesis deals with such a challenging task. Our aim is to deliver not only a sufficient accuracy but also a speed because we should be able to make the detection in real time. We use one of the newer model of neural network which is a convolutional network. This model is suitable for proces- sing image data a can use input image without any preprocessing whatsoever. After our detailed analysis we choose this model as a detector for hockey players. We have tested several different architectures of the networks which we then compared and choose the one which is not only accurate but also fast enough. We have also tested the robustness of the network with noisy patterns. Finally we assigned detected pla- yers to their corresponding teams utilizing K-mean algorithm using the information about their jersey color. Keywords:...

Title: The influence of skating frequency on muscle tone of musculus triceps surae. Objective: The aim of this master degree thesis is to determine whether and how much influence the frequency and intensity of isotonic load the muscle tone of musculus soleus during skating of a professional ice hockey player. The muscle tone of musculus soleus is the most objectively measured part of musculus triceps surae by myotonometer. Methods: The master degree thesis is divided into the theoretical part, the processed form of research that serves as a basis for investigation in the second, empirical part. Change in muscle tone of musculus soleus was investigated by using myotonometer, which followed after a full physiotherapy examination. It is quantitative research using quasi-experimental study. Measurements were performed on 10 subjects - professional ice hockey players who are fully manage the technique of skating on the ice, before load, after low frequency isotonic load and after high frequency isotonic load. Conclusion: The myotonometric measurements revealed that after low and high frequency isotonic load of skating on ice rink, the muscle tone of musculus soleus is the same or slightly lower than before load.

Summary: The master degree thesis is divided into the theoretical part, the processed form of research that serves as a basis for investigation in the second, empirical part.

Conclusion: The myotonometric measurements revealed that after low and high frequency isotonic load of skating on ice rink, the muscle tone of musculus soleus is the same or slightly lower than before load.

Title: Use of time in training the 3th grade Objectives of work: To find out use of time in training the 3th grade of czech teams and compare them with theoretical knowledge, which recommend ČSLH and USA hockey. Methods: Data were collected using the method of indirect observation. During our visits to selected clubs we made the video, which served us as a source of information and data for this work. Tested object represents 4 clubs in the Czech republic. The data from the video were processed into the charts, graphs created and the results compared. Results: In all four tested clubs players are actively in training unit over 25 % of the training time. Mountfield Hradec Králové and BK Mladá Boleslav join his players in training unit more than 50 % time of training. HC Stadion Vrchlabí waste time 12,1 % of training time, Mountfield Hradec Králové 12,8 %, Bílí Tygři Liberec a BK Mladá Boleslav over 25 % time of training. Skating and individual skills train in all tested clubs with the exception of Mladá Boleslav over 60 % training time. Three clubs applies small- area games over 30 % time of training. Only club HC Stadion Vrchlabí used these games in 17,5 % training time. Keywords: Ice hockey, time, training unit, 3th grade

Thesis title: Prevalence of hypermobility and its potential impact on ice hockey players injuries. Objectives: The primary goal of this thesis is to outline joint hypermobility based on available literature sources. Focus is on ice hockey players due to reason ice hockey is muscle and contact based sport. Secondary goal is to chart hypermobility presence on ice hockey players and detect possible connection between hypermobility and their previous musculoskeletal system injuries. There will be training improvement suggestions set according to analytical study results. Methods: Theoretical part is based on foreign literature and researches. Practical part quantitative analysis monitors selected joints injury frequency and is focused on joint hypermobility presence in selected junior professional male hockey players, 16 to 19 years old. Information regarding injuries where gathered by questionnaire and joint hypermobility test was set by test battery created for this research using clinical physical tests by Janda, by Sachse, and by Hospital del Mar criteria. Results were analyzed in Microsoft Excel 2010. Hypermobility and injured segments matches were further analyzed. Results: Results of this thesis clearly stated the answers for research questions which were placed. Prevalence of hypermobility in...
