Slánský, Martin ; Perič, Tomáš (advisor) ; Vojta, Zdeněk (referee)
Title: Virtual reality as a mean of diagnosis of the game intelligence in ice hockey. Goal: The goal of this work is to find out whether it is possible to evaluate virtual reality through the "game intelligence". Further on, to evaluate if different proband levels do affect the level of the "game intelligence". Methodology: File for research: Our goal is to test five different groups of various performance levels and evaluate the extent of change in game intelligence among respected groups. In each of the group we are evaluating 34 to 74 probands. In total, 252 people were tested. Statistic methods: Basic descriptive statistics, MANOVA analysis, correlation analysis, canonical correlation Conclusion: Our research could be of great benefit to the sports community. We believe that the results of our research will appeal to clubs that have doubts about the positive contribution of virtual reality to ice hockey. Key Words: Virtual reality, ice hockey, diagnostic, probands

Title: The possibilities of virtual reality as a training tool in sports games - on the example of a chosen sports game Objectives: The aim of this thesis is to find relations between variables consisting of selected hockey-specific skills and cognitive functions. Methods: Result evaluation was done via descriptive statistics (average result of research group, standard deviation) and correlational analysis (Pearson (common), canonical). Results: Research group was made of 197 probands (ice hockey players), whose ages were between thirteen and fifteen years. All probands performed eight tests in virtual reality, whereas first four of them focused on cognitive functions and the remaining four on hockey-specific skills. In case of hockey-specific skills, players accomplished following outcomes: release time (percentile) x=92,54+3,24 spatial orientation (percentile) x=70,07+14,29 looking for open lanes (percentile) x=59,64 +9,73 verbal communication (percentile) x=54,03+23,50 correct decision (percentile) x=58,87+14,98.

Title: Relation between power ratios of adductors, abductors, external and internal hip rotators at shooting speed of ice hockey players Objectives: The main aim of this thesis is to find out the relationship between the rate of fire on the ice and the strength abilities of the hand and hip rotators Methods: The research group consisted of 20 adult probands (age = 24.8 ± 3.4; height = 181 cm ± 6.13 cm; weight = 80.1 kg ± 9.9 kg). The research took place in the summer preparation period after the season. The laboratory tests were carried out at the Charles University FTVS under the supervision of qualified and trained experts. An isokinetic dynamometer (Cybex NORM ®, Humac, CA, USA) was used to test external and internal rotators. A hand isometric dynamometer (Takei 5401) was used to evaluate the handgrip. Field tests were conducted on the ice, where the rate of fire was recorded using radar (V-max). Results: The results showed a significant degree of association between SBN and SVN shooting and rotator force at concentric contraction (30ř∙s-1 , 90ř∙s-1 ) for the dominant leg, reaching values (r = 0.45) for the angular velocity of 30ř∙s-1 and at higher angular velocities it assumed values (r = 0.44 and 0.54). Statistical analyzes also showed a significant degree of association between SVN-firing and...
