Use of virtual reality to evaluate dynamic postural stability in beachvoleyball players
 Hlaváčková, Anna ; Pánek, David (advisor) ; Stupková, Michaela (referee)
Title: Use of virtual reality to evaluate the dynamic postural stability in beachvoleyball players Objectives: The aim of the study was to evaluate if the dynamic postural stability of trained beachvoleyball players is affected by training. Also I tried to evaluate, if the final score of equilibrium will be higher, than in regular population. For testing was also used virtual reality to stimulate vestibular apparatus. Virtual reality was used as a disturbing element. NeuroCom Smart Equi Test was used as an evaluation factor of dynamic postural stbility. Methods: The research involved a total of 20 females - 10 beachvoleyball players and 10 healthy persons performing activities of daily living. We investigated dynamic postural stability on device called NeuroCom Smart Equi Test. For evaluation of dynamic postural stability was used Head Shake Test - Sensory Organisation Test. This test was taken twice, second time after intervetion by virtual reality. Data were analyzed by statistical t-test method. Result: Statisticly significant result was found only in the case of a Sensory Organisation Test condiition 5 and 6 in comparison between both groups and Head Shake test-SOT2 in latero- lateral movement of the head at the controle group. The results confirmed the effect of playing beachvoleyball on...

Analysis of internal load for beach beachvolleyball players
 Čirka, Jan ; Vorálek, Rostislav (advisor) ; Kočíb, Tomáš (referee)
Title: Analysis of internal load for beach beachvolleyball players The aim of the work: The goal of this work is to determine the size of the musculoskeletal load of beachvolleyball players in several games of the Czech Cup. At the same time the objective of this work is to determine diffferences in size of the kinetic load between players on various positions and show in which levels and for how long time are players in each level during the match. Method: In this work is used indirect (mediated) observation. Data were recorded using the devices from which the information was subsequently processed in the result form. The assess the magnitude of musculoskeletal load were used sport testers "Polar Team 2." Results: The measurement results have shown, that beachvolleyball players were during the matches mostly in the aerobic - anaerobic zone. On average in selected matches harder working player was setter. Keywords: Beachvoleyball Fitness training Musculoskeletal load Heart rate
