Hank, Mikuláš ; Zahálka, František (advisor) ; Vorálek, Rostislav (referee)
The aim of this study was focused on the quantitative evaluation of movement distance of elite female volleyball players in match, and the comparison between the values of selected players. For the evaluation in the study was used 3D kinematic motion analysis. The observed homogeneous group consisted of elite female volleyball players at CEV Champions League match (n = 14, age = 25 ± 6 years, height = 182.3 ± 6.2 cm, weight = 72.1 ± 5.8 kg). Overal were processed four sets, a total of 167 rallies. The average movement distance of one player evaluated from 167 rallies was 1259.89 meters, the equivalent of one rally was 8.8 m. The average movement distance of Libero in one rally was bigger than the other players' (9.6 m). Results of this study has shown an interindividual differences in final volume of movement distance between group of players that was participating in every rally (spikers, setter, opposite player) and players that were not participating in every rally (libero, blockers). Comparison of average movement distance of players in one rally has shown no significant difference.

Kinematic analysis dinamic neuromuscular stabilization tests in people with low back pain.
Burešová, Vendula ; Valouchová, Petra (advisor) ; Kobesová, Alena (referee)
The main target of this thesis was to detect objective changes in the implementation of four postural locomotor tests DNS and during walking. The movements were recorded using the optical MoCap - the kinematic analysis Qualisys. The particular interest of the investigation was to determine the current stabilization of the spine system in individual subjects aged 25 to 55 years, which was documented by means of the angular deflection of each segment, the flat segment deviation or the shift of the marker in a coordinate system. The measurement results were compared between ten individuals with LBP and ten persons without any difficulty who were placed into the control group. The data were collected using the software QTM and Visual3D and subsequently were statistically processed. A statistically significant difference was observed during walking when comparing the angular deflection of the pelvis to the chest at the rotation and lateroflexion (ř). The significant difference of the pelvis shift toward the chest during flexion and rotation (ř) was showed in a deep squat test, but the difference was not confirmed in lateroflexion (ř). Furthermore, no statistical difference of the lateral deflection of the same segment (pelvis or chest) (cm) in patients with LBP compared to all subjects during the...

Kinematic Analysis of Tennis Serve
Havel, Michal ; Kočíb, Tomáš (advisor) ; Čichoň, Rostislav (referee)
Title: Kinematic Analysis of Tennis Serve. Objectives: To evaluate tennis serve realization in the selected performance category, to review speed of particular serve types and define the differences. To create detailed movement analysis of the slice serve from the right side of the court and set up a trajectory of the centre of gravity. Methods: Case study using kinematic 2D and 3D analysis was made. Results: We found out that the flat serve is the fastest type of serve. There are differences in the body centre of gravity trajectory by comparison with elite tennis players. We also found out that serving from the right side of the court is being hit higher, than from the left side. We assume there is a very close connection between serve speed and the point of impact. Keywords: tennis, serve, kinematic analysis, 2D, 3D

Selected parameters of gait and foot in consideration of the individual's body height
Strnadová, Hana ; Vilímek, Miloslav (advisor) ; Goldmann, Tomáš (referee)
Title: Selected parameters of gait and foot in consideration of the individual's body height Objectives: This thesis deals with a dependence of the selected gait and foot characteristics on a person's body height. These parameters are compared between a group of men and a group of women. In addition, a validity of selected formulas used for a determination of body height is evaluated. Methods: Mutual relation among the gait and foot characteristics and the individual's body height is observed. The thesis is a descriptive - association research, the comparative method is chosen in the practical part of the thesis. For an objectification of the research, the Plantograph and the 3D kinematic gait analysis performed by Qualysis system was used. Results: It was found out that the selected formulas used for a determination of body height are valid. The best results are brought by the formulas which count with a length of a bare foot, the length of a step and a double-step. On the contrary, the worse results are achieved by using the formulas which count with the dimension of shoe print. A tight dependence of the foot length and the length of the step / double-step on the body height was proven. A minimum dependence of the foot width on the body height was proven. Nevertheless the foot width is verifiably...

Manifestation of cerebellar dominance in the form of extinction physiological syndrome on upper and lower limbs and its relationship to human laterality
Rybář, Adam ; Musálek, Martin (advisor) ; Tlapáková, Eva (referee)
1 Title: Manifestation of cerebellar dominance in the form of extinction physiological syndrome on upper and lower limbs and its relationship to human laterality. Objectives: The aim of this diploma thesis is to determinate size of relationship between manifestation of cerebellar dominance in the form of extinction physiological syndrome and preference of limbs. Methods: A total of 27 individuals (male and female students of UK FTVS) were involved in the current quantitative research. We used indicators which were selected from Musalek's test battery (2013) to assess limb preferences. The evaluation of joint passivity asymmetry was based on angle and time parameters during walk and during controlled falls of forearm and shank on a constructed fall-machine. The movement was registered in real time by Qualisys Motion Capture System. For data analysis, descriptive statistics methods, paired t-test, level of statistical and substantive significance (Cohen's d) and tetrachoric coefficient of correlation were used. Results: Our research suggests that there is no significant difference in joint passivity when comparing preferred and non preferred limbs. Though it is necessary to take into consideration specifics and the size of research sample in which everybody was an active athlete. The result of tetrachoric...

Title: Analysis of the motion of dominant upper extremity during offensive stroke in badminton performed by elite female players Objectives: Objective of my master thesis is to analyse movement of a dominant upper extremity during offensive stroke in badminton and to point out possible risk factors for injuries and soft tissue overload problems in the region of the upper limb. Methods: The theoretical part deals with anatomical and kinesiological description of upper extremities. Then there is a description of the motion on the court and upper strokes in badminton and movements of upper extremity during the strokes. The practical part deals with measuring of rotations in shlouder joints and with analysis of motion of upper extremity during offensive stroke in badminton. It is focused on measuring the range of motion, angular velocity and angular acceleration in joints of dominant upper extremity. The Xsens MVN was used to record motion. Results: The results showed that the internal rotation in the shoulder joint on the dominant upper limb during active movement examination is reduced in elite female badminton players. When an offensive strike is played, the players come to the extreme inner rotation in the shoulder joint. Next we found out that the risky movement during the offensive stroke is...

The relationship between postural stability and physical activities
Gryc, Tomáš ; Zahálka, František (advisor) ; Janura, Miroslav (referee)
In the study "The relationship between postural stability and physical activities", we focused on determining the level of postural stability and the possibility of influencing by appropriate means of exercise intervention in people with increased physical activity and persons with physical limitations. Persons with increased physical activity were top players and players competing in various sports (football, handball, volleyball, golf) and those with physical limitations, patients suffering from diseases that have a negative impact on postural stability (Friedrich's ataxia, autosomal dominant spinocerebellar ataxia, Charlot-Marie- Tooth). Upright posture in stance and movement is a fundamental prerequisite for human bipedal locomotion. Postural stability is the ability to maintain an upright posture, which advises the motor and coordination skills, and its meaning is close to equilibrium abilities. Maintaining an upright posture is ensured by muscle activity, which is controlled by the central nervous system based on information from internal and external environment. Control of postural stability is the primary prerequisite for successful movement and as such it can be developed on the basis of appropriate physical activities. All methods of measuring static and dynamic postural stability can be...
