Opočenská, Kristýna ; Šteffl, Michal (advisor) ; Kinkorová, Ivana (referee)
Background: A healthy diet is often ignored even though it is an important element for younger school-aged gymnasts. The correct nutritional content in a diet may help enhance performance, reduce fatigue, accelerate recovery, and reduce the occurrence of accidents and injuries. Objectives: This bachelor's thesis summarizes the available information regarding the optimal diet for young, school-aged female artistic gymnasts and provides dietary recommendations based on their needs. Methods: A literature review was conducted and the results summarize the presently available data about healthy diets for young athletes, focusing on younger school-aged gymnasts. Information was obtained from the Czech and foreign literature and nutrition specialists' lectures, complemented with the author's own experience as a gymnastics coach. Conclusion: Although numerous publications have dealt with the issue of what constitutes a healthy diet for children and adults who participate in sport, neither the practical source of recommendations nor information on an optimal diet has been found for artistic gymnasts. In order to create optimal diet plans to meet the needs of young school-age female gymnasts, the author had to acquire data from materials related to other sports, modifying it slightly according to the...

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,...
