Master's thesis topic: Influence of rheological characteristics of muscle tissue by musculus triceps surae by means of AEK practice Author: Bc. Karel Kupec Branch of study: Physiotherapy Disertation Tutor: PhDr. Petr Šifta, Ph.D. Year of Defense: 2013 Abstract: The target of this thesis was find out the effect of agistic-excentric contractions on muscle tension of musculus soleus compared with passive relaxation of musculus soleus. The assumption was, that agistic-excentric contraction reduce muscle tension of musculus soleus after anaerobic load. The contralateral lower limb was control limb for comparison agistic-excentric contraction and passive relaxation. Muscle tension was measured in laboratory in Faculty of Physical Education and Sport, Charles University: five students were measured. As a measurement method was used myotonometry, which simulated palpation. Measured data were displayed by using an analog-digital convertor and consequently evaluated. The results of this study found out positive effect of agistic-excentric contraction on muscle tension. Control form of relaxation, passive relaxation, didn't influence muscle tension so significantly. The results support the principle of hypotheses, that agisctic-exentric contraction approach affect muscle tension more positive than passive...
