Title: Effect of strength training on postural stabilisation. Objectives: The main objective of the theoretical part of the thesis was to summarize the knowledge concerning postural stabilization, strength training and possibilities of postural stability evaluation. The aim of the practical part was to find out what is the effect of strength training on postural stabilization. Methods: The thesis was measured in the premises of the Laboratory of Biomechanics FTVS UK in Prague and was attended by 10 probands. Participants underwent a four-week training plan to develop general strength abilities. We evaluated the impact of strength training by our provocation test and its 3D kinematic analysis using Qualisys optical system. The measurement consisted of an input part before the intervention and an output part after the intervention. The measured values were analyzed in Qualisys Track Manager and then transferred to Microsoft Excel, where they were evaluated and compared. Results: The results showed a significant difference between input and output measurements of postural stabilization. There was a significant improvement in stabilization after four weeks of training, with a noticeable improvement in stabilization on the lower left limb. Properly selected strength exercise has a positive effect on...

Title: The effect of foam roller on muscle tone after physical load Objectives: The aim of this thesis was to summarize theoretical knowledge about muscle, changes in muscle tension and possibilities of its affect. The aim of the practical part was to find out the effect of the foam roller on muscle tone after exercise. Methods: Practical part of this thesis was processed in biomechanical laboratory at FTVS UK in Prague and included 16 probands. We measured muscle tone of biceps brachii, m. triceps surae and m. quadriceps femoris before exercise, then the probands performed an activity aimed at increasing the muscular tension of the musculature mentioned above, after which we measured the muscle tension again. The foam rolling of each muscle group lasted for 60 seconds and then we measured the muscle tone for the last time. A myotonometer device was used and the data were transmitted by KISTLER MULTICHANNEL CHARGE AMPLIFIER and processed by the DeweSoftX3 (64 bit) programme in SIRIUS DEWEsoft S-BOX2 computer. At the end, we compared measured values with subjective sensations of the probands who filled quick questionnaire. Results: The measurement showed that after exercise, the muscular tensions of the muscle groups we selected increased, and at the same time that the application of the foam roller...
