Svobodová, Alice ; Šteffl, Michal (advisor) ; Hráský, Pavel (referee)
Title: Body Posture in Disco Dance Performers Objective: The aim of this master's thesis is to examine how the body posture of disco dance performers changes with over eight years of competitive experience and to identify periods when the most significant deviations in body posture occur. The study compares the results of individual case studies among female participants and seeks to shed light on the issues of body posture specific to the disco dance style. Method: A qualitative research approach was employed, focusing on a deliberate selection of participants - disco dance performers. Selected tests assessed body posture using the methods of Mathias, Klein Thomas, and Mayer. Results: The master's thesis revealed that girls with over eight years of competitive experience often encounter issues related to pelvic tilt, specifically, 6 out of 8 girls exhibited anterior pelvic tilt as the most common finding. Another frequent problem was lordotic curvature of the spine, identified in 4 out of 8 girls facing this issue. The most pronounced deviations in body posture were observed in a 13year-old participant who obtained negative results in the Mathias test. Conclusion: Qualitative investigation suggested that crucial factors influencing body posture may include overloading and a high number of weekly...

Gavendová, Karolína ; Kočíb, Tomáš (advisor) ; Hráský, Pavel (referee)
Title: Neuro-athletic training in tennis Objectives: The bachelor thesis is divided into two parts. The first part is theoretical and its aim is to inform about neuro-athletic training and the possibilities of including this training in the tennis preparation of players of different age categories. At the same time, the theoretical part also provides a basic overview of the central nervous system and sensory systems on which neuro-athletic training is built. The goal of the second part is to create a stack of exercises that neuro-athletic training uses for tennis players of different age categories. The set of exercises will be divided into four sections - evaluation of training results, general exercises for visual, vestibular and proprioceptive training, neuro-athletic exercises for speed development, neuro-athletic exercises for strength development. Methods: In the theoretical part, we analyzed literature, internet resources and videos dealing with the topic of neuro-athletic training. Based on the analysis, we synthesized the individual findings in order to create a clear information base on the physiological aspects of tennis, the central nervous system and sensory senses, neuro-athletic training. Based on this information, we selected suitable neuro- athletic exercises and created a stack of...

Title: Assessment of the postural stability level by female soccer players using Y- balance test Objectives: The aims of this thesis are to acquaint readers with the Y-balance test method and to map the level of dynamic postural stability by women soccer players with the help of the method called Y-balance test and to compare the gained data with a group of non- athletic female probands. Amongst other aims is to identify the risks of injuring lower body limbs of the studied individuals based on the results obtained from the Y-balance test Methods: There were 20 probands in total attending the test. Half of them were female soccer players aged 18-30 years (21,8 on average) who practice 3 times a week plus play a competitive game once a week. The second half consisted of non-athletic female probands, also in age group of 18-30 (24,4 on average), who do not actively engage in any sports. Y-balance test was used to evaluate the postural stability of the subjects. Before the testing, the length of lower limbs was measured by the probands using a measuring tape, followed by trial attempts, after which the probands realized 3 measured attempts in each direction. The results were recorded on a special sheet. All the gained data were processed by Microsoft Office 2019, analysis was conducted using...

Title: The effect of the compensation program on the reduction of muscle imbalances for football players U17 and U19 Objectives: The objective of this study is to design and test the effect of a set of compensatory exercises for U17 and U19 soccer players that will lead to a reduction in muscle imbalances. Methods: The theoretical part used content analysis of documents and other scientific publications discussing muscle imbalances in football players. In the practical part, an entrance diagnosis was performed to detect muscle imbalances. In the practical part of the study 38 players (boys) of the U17 and U19 category of the MFK Chrudim football club were included. Both categories (U17 and U19) were divided into two groups, the intervention group and the control group. The probands were tested with a standardized protocol according to the muscle test according to Janda (2004). The rating scales were also taken from these tests. Furthermore, the testing was completed with tests according to Kolar (2009), focusing on the deep stabilization system (diaphragm test, intra-abdominal pressure test) and joint mobility of the lower limbs in the form of a deep squat test. Other tests used were the Thomayer test, deep- seated forward bending according to the test battery: the Unifittest (6-60), and an...
Relationship between hand grip strength and cognitive function in older adults over 65 years of age
Čutková, Michaela ; Šteffl, Michal (advisor) ; Hráský, Pavel (referee)
Title: Relationship between hand grip strength and cognitive function in older adults over 65 years of age Goals: The main goal of this diploma thesis was to find out possible links between hand grip strength and cognitive functions in older adults over 65 years of age Method: As part of the master's thesis, a secondary analysis of data from the international cross- sectional study conducted within the Survey of Health Ageing and Retirement in Europe (SHARE) project was performed. The participants of the study were divided into seven categories based on their educational attainment, separately for both men and women. Generalized linear models were calculated for each of the mentioned categories as part of the data analysis. Results: The survey included a total of 38,519 participants with an average age of 74.00 ± 6.7 years from 18 countries worldwide. More than half of the participants were women. In the data analysis, it was found that the most represented educational group among the participants was the third group with higher secondary education, as defined by the ISCED 2011 classification. The tables indicate that values of all percentiles increase linearly with higher levels of education. This result suggests that higher education is associated with better performance in the examined test....

Kunzmannová, Eva ; Hráský, Pavel (advisor) ; Nováková, Pavlína (referee)
Title: Rowing to improve physical fitness in the blind Objectives: To investigate the effect of rowing training on physical fitness of blind persons and descriptions of a blind rower. Methods: Three probands, men aged 30-50 years, were selected for the research. To collect empirical measurement data, a set of EUROFIT-TEST battery tests and times recorded over 2 km on a rowing trainer were used, these data were provided by the rowing club Paprsek from Ústí nad Labem. Results: During the two-month rowing training, an improvement in the physical fitness of the blind rowers was noted. Testing using the EUROFIT-TEST battery and times recorded over a 2 km distance on the rowing machine showed that, with one exception, there is a correlation between these results. Conclusion: Rowing training can positively affect the physical fitness of blind rowers, and the correlation of these positive changes is also reflected in the times measured on the rowing machine (2 km distance). There is also a positive influence in terms of somatic changes. Keywords: blindness, rowing training, changes in physical fitness, prevention, test battery

Cabrnoch, Bohuslav ; Hráský, Pavel (advisor) ; Heller, Jan (referee)
Title: Heart rate recovery as a predictor for VO2max and anaerobic threshold Objectives: The aim of the study was to determine the statistical relationship between the maximum VO2max values at standardized loading, with a decrease in heart rate after maximal loading, and functional anaerobic threshold values. Methods: Ten healthy men, aged 22-26 years, participated in the testing. The probands had their blood pressure, weight and height measured before testing. Subsequently, they were fitted with a silicone spiro-ergometric mask and chest belt to measure heart rate. After stepping on the treadmill ergometer, standing spirometry (FEV1/FVC) and minute ventilation in sitting were performed. In the warm-up, probands completed a run for 4 minutes (11 km/h, 0 incline). In 5th minute the incline was set to 5. From the 6th minute onwards, the speed of the treadmill ergometer was increased by 1 km/h every minute until the proband could not continue. After the run, the proband was seated and heart rate was measured for 5 minutes along with spirometry. Results: Although there was a positive correlation between the heart rate recovery after 30 s, 90 s and 240 s after maximal load and peak values of VO2max, these correlation (r = 0,51, r = 0,49, r = 0,53) are not strong enough to generalize the results. No...

Pavlík, Michael ; Hráský, Pavel (advisor) ; Nováková, Pavlína (referee)
Title: Relationship between long-term compensatory exercise intervention and strength- velocity parameters in young football players Objectives: Based on the diagnostic examination, compile a compensation program for the intervened group in order to improve the functional state of the locomotor apparatus and monitor whether this intervention is reflected in the performance in the given motor tests that test the strength-speed abilities of the players Methods: The "20-m linear sprint test" was used to measure linear speed and acceleration, which was measured using time photocells (Witty Timing System). In this test, the average times of all groups were monitored at distances of 5, 10, 20 m. Furthermore, with the help of photocells, a 505 agility test was measured to determine the speed of the players' change of direction. The last test was "Standing broad/long jump" measured by the method (Laser-method measurement SDJ) using a laser optical range finder (Mestek GR20). To determine the normality of the data, the Shapiro-Wilk test was used, the results of which do not reject the normality of the data. For statistical analysis was used paired T-test data between individual measurements in individual groups. MS Excel and Jamovi software were used for recording data and their subsequent analysis....
