Association between Motor and Cognitive Development in Preschool Children
Brodská, Kateřina ; Musálek, Martin (advisor) ; Maulisová, Alice (referee)
The thesis focuses on the relationship between motor constructs from Stodden's model, and cognitive development in preschool-age children. The objective of the study is to determine the significance of these relationships within the structural model. The theoretical background of cognitive and motor development in preschool-age children is described in the literature review section, followed by an overview of the current state of knowledge in the field of professional literature. The empirical part is designed as a quantitative research study with the aim of investigating the extent of the relationships between motor constructs and cognitive development. Data on cognitive functions were collected through the use of the IDS-P method's subtest. The level of motor skills was assessed using internationally recognized motor tests and methods, namely TGMD-2 (Test of Gross Motor Development) and MCA (Motor Competence Assessment). The results indicated possible significantly positive correlations between motor competencies and selective thinking, as well as between motor competencies and conceptual thinking. Negative correlations were found between physical activity and phonological memory, as well as between physical fitness and selective attention. Additionally, as hypothesized, there was a relationship...

Kocík, Martin ; Kokštejn, Jakub (advisor) ; Musálek, Martin (referee)
Title: Evaluation of the relationship between general motor coordination and game performance of football players due to different biological age. Objectives: Finding the relationship between the level of the level of motor coordination and the subjective assessment of game performance of football players by the coach due to biological age and the different pace of biological maturation of football players in pupils categories (U12-U14). Methods: The research group consisted of 43 players (average age 12.8±1.0 years) from pupils categories (U12-U14) from the professional club in the Czech republic. The method of dual energy X-ray absorptiometry (DEXA) was used to determine biological age. The Körperkoordinationtest für Kinder (KTK) was used to assess the level of motor coordination. Game performance was evaluated using a questionnaire filled out by the coaches of the individual categories. Results: Of the entire research population, 65,12 % of players achieved verbal ratings of "excellent", 32,55 % "above average" and 2,33 % "average". The most correlated variable with the performance evaluation was the subtest from the KTK "jumps on one leg", which had a correlation of 0,43. The game performance questionnaire correlated only 0,13 with the motor quotient from the KTK test. Playes with the best...

The relationship between verbal intervetion and postural stability
Švátora, Karel ; Čepička, Ladislav (advisor) ; Musálek, Martin (referee) ; Válková, Hana (referee)
Dissertation Karel Svatora ABSTRACT Title: The Relationship between verbal intervention and postural stability Objective: To evaluate whether there is a relationship between verbal intervention and manifestations of postural stability. Methods: In the submitted work, 3 research investigations were carried out. The first investigation involved 185 probands (84 men) and was focused on verifying the effect of psychological priming. The Posturograph STP-03 was used to assess postural stability. Probands were randomly divided into three groups and each received different information about the difficulty of the upcoming task. An electrodermal activity data was recorded during the investigation. The second investigation involved 88 probands (45 men) and was aimed at verifying the effect of persuasive communication. The test of postural stability was to remain in a standing position measured on a 3 cm wide beam. Probands were randomly divided into two groups. The groups received the opposite verbal intervention during the test. 142 probands (83 men) took part in the third investigation. It was aimed at verifying the effect of persuasive communication during more significant stimulation of the current psychological state. The test of postural stability was to remain in a standing position measured on a 3 cm wide...

The relation of laterality and selection of rotation direction in U12 figure skaters
Hájková, Klára ; Sedláčková, Marie (advisor) ; Musálek, Martin (referee)
Title: The relation of laterality and selection of rotation direction in figure skating at children in preschool and younger school age Objectives: The aim of the thesis is to construct a test battery on the ice surface, to assess the laterality, i. e. the preferred lower limb and the preferred side of rotation and turning, for beginning figure skaters in preschool and younger school age. Subsequently, individual items of this test battery are examined with items from the standardized test battery for the child population aged 8-10 years, according to Musálek (2013). The relationships of individual test items are determined in order to determine whether the individual test items on the ice surface can be used to represent a relatively reliable tool for determining the rotation direction of a beginning figure skater. Methods: We use testing by standardized battery of tests according to Musálek (2013) for the diagnosis of motor manifestations of laterality for children aged 8-10. Next is used testing by created test battery on the ice surface, which should fulfill the purpose of demonstrate the preferred lower limb, or the preferred side of rotation and turning. Results: Test battery created for use on the ice surface shows some reliability only for test items that are designed to express the...

Somatotype and off-ice performance as predictors for long term hockey perspective in youth ice hockey players
Pilná, Petra ; Musálek, Martin (advisor) ; Vojta, Zdeněk (referee)
Title: Somatotype and off-ice performance as predictors for long term hockey perspective in youth ice hockey players. Objectives: The aim of this thesis was to determine whether a player's somatotype and performance in selected off-ice tests predict a player's hockey perspective judged by coaches in youth hockey of the highest domestic competition. Methods: The thesis included 112 hockey players in highest youth league. The off-ice tests included 1. Illinois agility, 2. Illinois agility with a ball, 3. Five jump test, 4. Sit and Reach Flexibility Test, 5. Squat Jump, 6. Free Arm Countermovement Jump, 7. Pull ups, 8. 1500 m run. The somatotype was evaluated according to the method of Heath and Carter (1990). The analysis of variance with repetition was used to compare performances over time with respect to somatotype categorization. A paired T-test with a confidence level of 95 % (p < 0,05) was used to assess potential within-survey. Cohen's d was used for the paired T-test to estimate the clinical significance (effect size), with Cohen's d ≤ 0.3 determined as the clinically significant effect size. To estimate the degree of influence of the selected off-ice tests on game perspective was assesed by multiple regression analysis with significance p < 0,05 and adjusted R2. Results: The only significant...

Pocovidic changes in physical activity of children at school.
Legová, Tereza ; Peřinová, Radka (advisor) ; Musálek, Martin (referee)
Title: Post covid changes in childrens' physical activity at school Objectives: The aim of this diploma thesis was to find out whether and how the recommendations of ČŠI Inspiration for the support of pupils' movement skills in various school activities were implemented in Czech schools during the daily regime except physical education classes in the school year 2021/2022. Methods: The practical part is based on a questionnaire created in Google Forms, which finds out the current state of support for physical activities (according to ČŠI recommendations) and compares it with the state before the covid-19 pandemic. The questionnaire was sent to a stratified selection of schools using an online service called Mailchimp. The results were statistically processed in Google Spreadsheets. Results: Most of the addressed schools are acquainted with the recommendations of ČŠI Inspiration for the support of pupils' movement skills in various school activities and apply it in practice. Prior to the outbreak of the covid-19 pandemic, schools already implementing this ČŠI recommendation were then generally more active in supporting pupils' physical activities in the schools year 2021/2022. Both the schools that apply the ČŠI recommendations and those which do not showed a similar level of support for physical...
