Software for processing data from the accelerometer
Zahradník, David ; Vetiška, Jan (referee) ; Kovář, Jiří (advisor)
This thesis deals with the creation of software for statistical processing of data from the accelerometer. In the first part are specify the objectives. The next part of the thesis is followed by design and creation software for statistical processing of data in real-time as well as post-processing mod. Final program is tested by using stored data from the accelerometer. At the end the functionality of the created software is evaluated. This program is created by using the programming language C #.

Analysis of a pressure distribution on the level of foot and shoe interaction when running in flatlands with minimalist and sport shoes.
Charousek, Jan ; Jandová, Soňa (advisor) ; Zvonař, Martin (referee) ; Zahradník, David (referee)
Problem: Running is one of the most widespread physical activities. Incorrect running technique, training quantity but also the runner's equipment can strongly affect health condition of the individual, both positively and negatively. For that reason various trends emerge in the area of running footwear. They include classical sports shoes with different types of impact attenuation as well as the minimalist footwear made to imitate barefoot running, which should be much more natural for humans, as insisted by B. Nigg in his book "Born to Run" - where he says that man was born to walk and run barefooted. Inappropriate shoes can cause various health complications, not only in the foot area. Objective: To find out how foot strike changes in the area of the foot-shoe interaction in running on flat ground when an amateur runner uses minimalist and sports footwear and to draw conclusions for training practice on the basis of the results. Methods: The thesis deals with amateur endurance running in different shoe types (minimalist and sports shoes). The study specimen consisted of 14 female runners (mean body weight 63,31 ± 4,89 kg, height 169,69 ± 4,71 cm, age 31,92 ± 5,34 years, speed in minimalist shoes (MO) 3,34 ± 0,06 m.s- 1 , speed in sports shoes (SO) 3,29 ± 0,06 m.s-1 , weekly mileage 37,54 ± 9,43...

Analysis of the sports game loading by help of volleyball example
Hank, Mikuláš ; Zahálka, František (advisor) ; Lehnert, Michal (referee) ; Zahradník, David (referee)
The aim of this dissertation was to evaluate and statistically compare the data of the distance of movement and player load (PL) with respect to the player specializations and with respect to the result of rallies. The analysis used the method of 3D kinematic motion analysis of a video recording of the official play-off match in the elite women's category. 3D reconstruction accuracy was calculated with a standard deviation of 0.0296 m (0.3%). A total of 14 players were evaluated (age = 25 ± 6 years; height = 182.3 ± 6.2 cm; weight = 72.1 ± 5.8 kg) in a total of 4 sets. 85% of all rallies lasted up to 12.4 s and 95% lasted up to 18 s. The average duration of the rally reached 7.76 ± 5.1 s. In the range of 0.7 m to 2 m was performed 91.8 ± 1.3 % of distance of movement over 0.7 m. In the range of 0 m to 0.7 m, the specialization spiker reached 60.5% of the total distance of movement. For blocker it was 59.8%, setter reached 54.1%, Opposite reached 62.1% and libero 57.9%. The highest ratio of movement was reached by the spiker for the forward direction (35.8%). The highest distance of movement was reached by the setter (1648 m). Players reached at 50 % speed value from 1.32 m/s in the backward direction for the blocker and setter, up to the maximum speed at 50 % for the setter with a value of 2.09 m/s...

Evaluation and setting of standards of conventional ratio of flexors and extensors of knee of young athletes
Ižovská, Jana ; Zahálka, František (advisor) ; Džupa, Valér (referee) ; Zahradník, David (referee)
Title: Evaluation and determination of standard ratio of extensors and flexors of the knee in sporting youth. Objectives: The aim of the thesis is to establish the standards of the force ratio H: Q for the youth football categories U16, U17, U18, U19, U21 and adult players of the Czech Republic and based on the prescription type of study to establish a percentage critical disbalance of dynamic knee stabilizers which may be the most common cause of injuries to dynamic or static knee joint stabilizers in soccer players. Methods: The monitored group of players consisted of football players playing in elite Czech football clubs, both in youth and senior categories, who meet the predetermined selection criteria. The isokinetic strength parameters were monitored using a Cybex Humac Norm isokinetic dynamometer (Cybex NORM ®, Humac, CA, USA). We investigated maximum strength moment (PT) of extensors and knee flexors of dominant and non-dominant limb at concentric contraction at angular velocities of 60, 180 and 300ř.s-1 . Then we watched the players wounded. If the injury occurred, then we looked back at its strength characteristics and the strength ratio between the extensors and flexors of the knees and whether it was possible to predict the injury and determine the critical level that indicates the...
