Obyt, Daniel ; Šifta, Petr (advisor) ; Nováková, Pavlína (referee)
Title: The influence of skating frequency on muscle tone of musculus triceps surae. Objective: The aim of this master degree thesis is to determine whether and how much influence the frequency and intensity of isotonic load the muscle tone of musculus soleus during skating of a professional ice hockey player. The muscle tone of musculus soleus is the most objectively measured part of musculus triceps surae by myotonometer. Summary: The master degree thesis is divided into the theoretical part, the processed form of research that serves as a basis for investigation in the second, empirical part. Change in muscle tone of musculus soleus will be investigated by using myotonometer, which will follow after a full physiotherapy examination. Measurements will be performed on 10 subjects - professional ice hockey players who are fully manage the technique of skating on the ice, before load, after low frequency isotonic load and after high frequency isotonic load. Conclusion: The myotonometric measurements revealed that after low and high frequency isotonic load of skating on ice rink, the muscle tone of musculus soleus is the same or slightly lower than before load.

Stránský, Vojtěch ; Šifta, Petr (advisor) ; Otáhal, Jakub (referee)
Title: Influence of crank arm length on change of muscle tone of musculus triceps surae Objectives: The aim of this thesis is to conclude the theoretical knowledge of this issue. The experiment is to uncover via the objective results, if the change of the crank arm length can influence the muscle tone of m.triceps surae and additionaly how much. Methods: The measurement for this thesis was processed at Charles University at the Faculty of Physical Activity and Sports, measuring 8 volunteers. Via myotonometry, the biomechanic properties (stiffness and viscosity) of m.triceps surae were measured before and after the workout on a bicycle ergometer. These steps were repeated twice within a week with different crank arm length (170mm and 175mm). On the basis of the reaction of soft tissues on deformation from the tip of the myotonometer, the graphs are depicted, containing the hysteresis curve. We evaluate there two phenomenons - steepness and the content of the curves. They indicate biomechanic properties of soft tissues, resp. also the muscle tissue. Results: The measurements from the 1st and 2nd week were compared. The results of 8 probands show that cycling as a physical activity changes stiffness and viscosity of m. triceps surae and has therefore an influence on the muscle tone. Considering larger...

Title The influence of muscle tonus with hormonal contraception Objective The thesis aims to determine whether and to what extent the use of hormonal contraception affects muscle tension, which can vary depending on the current phase of the menstrual cycle in women. Method The thesis is divided into theoretical part where there is a summary of information on this topic from the literature Czech and world, a special part that is treated as research using noninvasive myotonometer. The measurement is performed in 12 probands four times in four weeks, always at some stage of their menstrual cycle. The measurement results are compared between the two groups by probands and is found to influence hormonal contraceptives on muscle tension during the menstrual cycle. Results Measurement myotonometer shows that hormonal contraceptive use affects muscle tension. The measurement results show a stable and predictable changes in fluctuating muscle tension in probands who use hormonal contraceptives, but the rate changes are subject to interpersonal differences, and these results can not give a general opinion.
