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....

The relationship between facial morphology and physical strength: Testing of the Other-Race effect hypothesis
Klusáčková, Tereza ; Třebický, Vít (advisor) ; Pokorný, Šimon (referee)
Existing evidence shows people are able to attribute an individual's behavioural characteristics based on their facial features with a certain level of accuracy; one such characteristic is the perception of physical strength in potential opponents within the male intersexual competition. Physical strength seems be assessed upon the level of masculine facial features development. However, attributions may be influenced by other factors - namely personality traits of the evaluator or the so-called Other-race effect. In this study portrait photographs of men from Europe and Africa were rated by a group of European evaluators on a perceived physical strength. The aim of this study was to assess the link between attributed physical strength, actual physical strength (grip strength) and facial morphology described by relative facial width (fWHR) the Index of Masculinity (potential effects of age, body weight and height on said variables were controlled for). The use of stimuli of different ethnic origin enabled us to test the accuracy of physical strength attributions and actual physical strength in context to the Other-race effect hypothesis. According to its wording people tend to attribute characteristics with higher accuracy to individuals, who belong to the same population, or with whom they are...

The level of selected indicators of body composition and handgrip strength in sporting youth in the Czech Republic
Bednaříková, Anna ; Šteffl, Michal (advisor) ; Chrudimský, Jan (referee)
Title: The level of selected indicators of body composition and handgrip strength in sporting youth in the Czech Republic Objectives: The main aim of the bachelor thesis was to find out differences in selected indicators of body composition and handgrip strength of sports youth in four selected regions of the Czech Republic. Methods: 1188 children participated in a cross-sectional study. Participants were recruited from the sports festival for children Sporťáček in these selected regions: Prague, South Moravian Region, West Bohemian Region, and South Bohemian Region. Results: The average age of the study population was 8.8 (2.7) years. There were 51% of girls in this survey. The largest representation was in the South Moravian Region (38.8%), Prague was the second largest region represented by 37.5%. Conclusions: Selected indicators of body composition as well as handgrip strength differed statistically significantly only slightly across the selected regions. Key words: body composition, handgrip strength, skeletal muscle mass

Relationship between forced vital capacity and hand grip strength in children
Novák, Ondřej ; Šteffl, Michal (advisor) ; Petr, Miroslav (referee)
Title: Relationship between forced vital capacity and hand grip strength in children Objectives: One of goals of this thesis is to find out how strong is the connection between the strength of a children's handgrip and the FVC. Another aim is to ascertain what is the age limit to use a handgrip examination to estimate the children's FVC. The last goal is to determine whether a body height, weight and age of a child are crucial to evaluate the handgrip and the FVC. Methods: First part of this thesis is a research and tries to summarize basic information about an issue of dynamometry, spirometry and to characterize each of age brackets which are the main aim of this thesis. Second part of this work is a survey for which data from sport festivals for children and youth were assembled. This data were statistically processed to calculate correlation and to make graphs showing linear regression between observed variables (handgrip and FVC), finally the results were interpreted. Results: Between the handgrip and the FVC was proven a strong correlation (girls , boys ). It is possible to evaluate FVC with younger school age children from the value of handgrip's strenght. Values of strenght of a handgrip are strongly influenced by body length, weight and age of a child. Keywords: strenght of a handgrip, FVC,...

Reference value for handgrip strength and skeletal muscle mass for children aged 4 to 12 years in the Czech republic.
Vrba, Jakub ; Šteffl, Michal (advisor) ; Kinkorová, Ivana (referee)
Title: Reference value for handgrip strength and skeletal muscle mass for children aged 4 to 12 years in the Czech republic. Objectives: The main aim of this study was to create reference values for handgrip strength dependent on body mass index (BMI) and for skeletal muscle index (SMI) among children in the Czech republic. Methods: 442 children participated in this study realized in five different places of the Czech republic. There were used bioelectrical impedance analysis to body composition and isometric handgrip dynamometer to handgrip strength measurements. Results: Reference values of handgrip strength dependent on body mass index (BMI) and skeletal muscle index (SMI) were calculated. Percentile nomograms for both genders separately are provided according to age from 4 to 12. Conclusion: Handgrip strength dependent on BMI as well as SMI increased with age in both genders. Boys showed higher level in both variables, nevertheless, the only in SMI there was a statistically significant difference. Keywords: Handgrip strength, skeletal muscle mass, BMI, SMI
