Author: Bc. Simona Bartošová Title: Effect of sensomotoric insoles on postural stability in children with cerebral palsy Objectives: Objectively assess the effect of sensomotoric insoles on children with cerebral palsy (CP) via COP (Centre of Pressure) parameters recorded on Kistler force plate. Methods: This thesis is designed as an experimental study. Selected paramaters of static postural balance were recorded via force plate to assess the effect of sensomotoric insoles. Five subjects (average age 7.2 years) with diagnosis of cerebral palsy were enrolled into the study. Data collection was carried out in two separated sessions - first before therapy and second after using the insoles for one month. The validity of the data was supported by three repetitions for each modification - upright plain stand with open eyes, upright stand with feet together and upright plain stand with closed eyes. Monitored parameters were: total trajectory of COP, amplitude of mediolateral displacement of COP, amplitude of anteroposterior displacement of COP and mean velocity of movement of COP. The data were analyzed in MATLAB® version R2019b. The statistical analysis was performed including the outliers elimination. The normality of data was checked by Lilliefors' test. In the case of normality a two-sample Student's...

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...

Vyhnálek, Vojtěch ; Gryc, Tomáš (advisor) ; Červinka, Pavel (referee)
Title: The difference in kinematic and kinetic parameters of running using running shoes, barefoot and shod Objectives: The aim of this bachelor thesis is to analyze the kinematic and kinetic parameters of running using different types of shoes. We tested a sample of four probands aged 20-25 years male. Using applied clusters, we examined the differences in individual runs. Methods: The experiment was attended by 4 runners (men only) who completed a monitored run on a 3D running ergometer at several speeds. A CODA Motion System 3D kinematic analyzer with the appropriate ODIN software was used to evaluate the kinematic parameters, and a 3D running ergometer with implemented power plates and h / p cosmos designed software was used to evaluate the kinetic parameters. The measurements were one-time. The obtained data were processed in Microsoft Excel 2019, where the tables used in this work were created. Results: All subjects demonstrated an immediate change in technique during the transition from running shoes to minimalist shoes and then barefoot. The most significant changes took place in the tread angle, the ankle angle, the cadence of the steps and the force produced by the impact. However, changes in the monitored parameters did not lead to the correct running technique in barefoot shoes, which...

Benešová, Amálie ; Gryc, Tomáš (advisor) ; Prokešová, Eva (referee)
Title: Structural and functional asymmetry in golfers aged 12 - 18 Objectives: The aim of this study was to determine the level of body composition parametres, postural stability, muscle shortening and joint mobility of junior golfers and identify and analyze structural and functional asymmetry. Methods: The 14 golfers participated in this study (n=14, age 15,8 ± 1 year, body height 174,5 ± 10 cm, body weight 67,6 ± 13 kg and HCP 5,4 ± 5,9). Body composition including segmental muscle's weight distribution was tested on a bioimpedance instrument Tanita (Japan). Furthermore, the postural stability was examined on the Footscan (Balance 7.6 software) in 4 positions (USOO, USZO, FL_L and FL_P). The kinesiological analysis made by physiotherapist mainly tested muscle shortening and asymmetry using Janda's muscle function tests (1996). The dependence between the measured data was determined by the Pearson coefficient. Results: The average muscle's weight distribution was 2 % higher in the lower right leg, 3,1 % higher in the upper right arm compared with the left limbs. Asymmetry was also found in postural stability (average difference between stability on the right and left lower extremities was 25.9 %). Muscle shortening was found in more than 70 % of probands in hamstrings and quadriceps femoris,....
