The comparison of strength of lower limbs in different ski and snowboard disciplines
Tišer, Kryštof ; Jindra, Matouš (advisor) ; Gnad, Tomáš (referee)
Title: Comparison of explosive strength of lower limbs in different ski and snowboard disciplines. Aims: The aim of this thesis is to compare explosive strength of lower limbs in different ski and snowboard disciplines. Methods: This is an empiric-theoretical thesis. A simple experiment (testing) was used to verify the hypothesis. 6 used sets participated in the quantitative research. Testing was carried out using two standardized tests, broad jump and vertical jump (Sargent jump). In both tests the best of the three trials was evaluated. Results: In two tests for the explosive strength of the lower limbs significant differences in this ability were shown between some ski disciplines and snowboardcross. The best results in both tests were achieved by representatives of alpine skiing which disproved our hypotheses. Only the expectation that ski jumpers would perform better than the nordic combination was fulfilled. Key words: explosive strength, broad jump, vertical jump, skiing, cross country skiing, grass skiing, nordic combination, ski jumping, alpine skiing, snowboardcross

History of ski jumping in Czechoslovakia and Czech lands
Hánková, Anna ; Kašpar, Ladislav (advisor) ; Přibyl, Ivan (referee)
The thesis deals with the history of ski jumping in the area of the Czech Republic. Based on the available sources it presents a concise description of the development of skiing and ski jumping, not only in the Czech lands but also in the countries where these sports originated. Through subsequent study it proceeds to focus on key points in the historical transformation of ski jumping. The thesis deals with the construction of jumping hills, measuring the length of a ski jump and its scoring as well as the ski jumping technique. The thesis also maps the Czech regions where the ski jumping has been practiced traditionally, more thoroughly focusing on the most important centres today, namely Harrachov, Liberec and Frenštát pod Radhoštěm. In the end the thesis introduces selected representatives of the Czech ski jumping sport, both of the glorious past and the present.

Possibilities of physiotherapy for chronic overtrain of ski jumpers locomotory system
LATZKOVÁ, Darina
This bachelor thesis deals with possibilities which physiotherapy offers to ease chronic overstrain of locomotor system of ski jumpers and it is especially focused on children of younger school age. Ski jumping is an individual sport of acyclic character whose main aim is to perform a technically correct ski jump as long as possible. Big demands are placed on locomotor system in the process of reaching this result. Big load and strain on locomotor system can lead to formation of muscular dysbalance or functional disorders deteriorating stability, coordination and performance of the sportsman and on the other hand they increase the risk of fall and a subsequent injury of the ski jumper. The thesis is divided into two parts. The first part represents theoretical findings, e.g. what ski jumping is, the history of the sport and analysis of particular phases of a ski jump which follow one another from kineziologic point of view. The theoretical part contains summary findings about locomotory system overloading with subsequent formation of functional disorders and suggesting concrete general and also specific methods used in therapy. The second, practical part represents the method of qualitative research. The research was based on case interpretation containing collecting anamnestic figures of a patient, preliminary analysis and suggestion of short-term therapeutic plan, the process of particular therapies and subsequent final analysis, general evaluation of the therapy and suggesting a long-term therapeutic plan. Collecting figures was pursued through interviews with patients and coaches, during observation and obtaining anamnesis and kineziologic examinations. The examined team was formed by three ski jumpers from the Sports Club in Nové Město na Moravě. The therapy went on three times a week for three months. Twice a week there was autotherapeutic exercise and once a week there were meetings in the grammar school gymnasium or rehabilitation department in Nové Město na Moravě. Techniques of soft tissues, mobilization, gentle traction, joint centration, post-izometric relaxation, stretching and breathing exercises, deep stabilization system activation, elements of the school of the back, exercises for flatfeet, proprioceptive neuromuscular facilitation, sensomotoric stimulation, kinesio taping, elements from dynamic neuromuscular facilitation, Klapps crawls exercises and brace exercises according to Roswithy Brunkow were used during the therapy. The aim of the thesis was to deal with the problem of ski jumpers locomotory system overstraining from the point of view of physiotherapy and suggesting possibilities of concrete methods of kineziotherapy and physiotherapy as the prevention of injuries and overstrain. The results show that the chosen therapeutic system more or less positively influenced the condition of the three patients. The hypertonic cervical muscles was reduced, some shortened muscles mostly of lower limbs were treated, slight strengthening of lower fixator muscle of scapulas as well as of longitudinal and transverse foot arch led to better postural position and reduced muscular dysbalance. The possibility to influnce chronic overstrain of locomotor system of ski jumpers is real but it needs long-term and intensive training. The worked out material can help education and better orientation in this field not only physiotherapy students but also coaches and ski jumpers themselves.
