Analysis of voleyball players' movement during the match
Hank, Mikuláš ; Zahálka, František (advisor) ; Vorálek, Rostislav (referee)
The primary task of this thesis was to evaluate, quantify and objectify distances of movement of elite volleyball players in terms of individual game specializations in the horizontal plane of motion. Secondarily, these values were mutually compared. For evaluation was used 3D kinematic motion analysis. Analyzed homogeneous group consisted of senior volleyball players at the Champions League level (n = 14; age = 25 ± 6 years; height = 182.3 ± 6.2 cm; weight = 72.1 ± 5.8 kg). Processing were four sets, a total of 167 rallies. The average distance one player absolved for 167 rally was 1259.89 meters in whole game, per rally, this value was 8.8 m. The movement of players was divided by a total of four directions relative to the volleyball net forward, backward, left and right. The results showed a high degree of homogeneity in the external load players and brought objective values for comparison between the players' specializations. Powered by TCPDF (www.tcpdf.org)

Human locomotion after total hip replacement
Horáková, Alena ; Vilímek, Miloslav (advisor) ; Horák, Zdeněk (referee)
Title: Human locomotion after total hip replacement Objectives: The aim of this thesis is to perform a gait analysis of patients after total hip replacement and to find out, how chosen temporo-spatial, kinetic and kinematic parameters change during the first half a year after the surgery. The deviations found in gait stereotypes of individual patients are further compared with results of international studies. Methods: The thesis is theoretical-empirical, with small number of patients. 3D kinematic gait analysis was performed by Qualisys system and ground reaction forces by two Kistler force plates. The following parameters are being monitored: length of step, stance phase duration, cadence, walking speed, lateral shift of the pelvis and trunk in standing phase, contralateral pelvic drop in standing phase of the leg, maximum range of motion of the hip joint in sagital plain, maximum of vertical and medio-lateral component of the ground reaction forces in the standing phase. Results: The highest side deviations between legs were found in 3 months after the surgery and remained until 6,5 months after the surgery. In this time period a lower value of the length of step, stance phase duration, maximum range of motion of the hip joint in sagital plain and also a higher lateral shift of the pelvis was...

Analysis of upper limbs muscles involvement during playing the drums
Štumpfová, Lenka ; Nováková, Tereza (advisor) ; Véle, František (referee)
Title: Analysis of upper limbs muscles involvement during playing the drums. Objectives: The aim of this thesis is to compile information about playing the drums and summerize the most frequent musculosceletal disorders of upper extremities of these musicians. The main aim is analyzing and comparing the involvement of muscles or muscles groups of the right upper limb while drumming. Methods: The theoretical part follows up the given issue as a research and theoretical overview of the current findings based on czech and foreign literature. The practical part is dedicated to evaluation of surface electromyography and 3D kinematics analyses of movements while drumming under specified conditions of one single proband. Results: Results of measurement demonstrate that m. biceps brachii is the most active muscle during playing on hi-hat, snare drum and floor tom with forte dynamics and m. extenzor carpi uln. is is the most muscle active during play with piano dynamics. Wrist flexors were the least active during all measurements. M. extenzor carpi rad. was measured too and its activity was on second place. A close relation between changes of muscles activity and changes of angles of the elbow and wrist have not been established in this study. This research was implemented only with one proband so the...

Golf swing in subjects with amputation of lower extremity
Richtrová, Michaela ; Otáhal, Jakub (advisor) ; Šifta, Petr (referee)
Author: Bc. Michaela Richtrová Tittle: Golf swing in subjects with amputation of lower extremity Objectives: The study aims at evaluation of the technique of golf swing used by patients with a different type and level of lower extremity amputation as compared to able-bodied golfers. Another objective is determination of the relation between individual phases of the golf swing and weight transfer, using different golf clubs, as compared to able-bodied golfers. Method: By its topic the work is a pilot study. The research has been divided into three descriptive case studies. The experimental group included two amateur golfers and one professional golfer. The control group was represented by an able-bodied golfer. Evaluation of kinematic parameters (trajectory of shoulders, hips, knee joints) was based on the Qualysis Motion Capture System. Evaluation of dynamic parameters (weight transfer) in the course of golf swing was made using two dynamometric Kistler platforms. Results: The measuring has demonstrated that in terms of both kinematics and dynamics, the mode of movement of a patient with a trans-tibial amputation during a golf swing corresponds to that of an able-bodied golfer. The same results were achieved by the patient also with the use of another type of golf club. A change, both in terms of...
