The influence of foam rolling on range of motion, strength of the knee extensors and flexors, and H/Q ratio
Šablatúra, Michal ; Šteffl, Michal (advisor) ; Větrovský, Tomáš (referee)
Title: The influence of foam rolling on range of motion, strength of the knee extensors and flexors and H/Q ratio. Objectives: The aim of the diploma thesis was to determine the effect of the foam roller on the range of motion and strength of the extensors and flexors of the knee joint. The muscular strength of the knee extensors and flexors was determined using a Humac norm isokinetic dynamometer. Another goal was to determine the effect of the foam roller on the force ratio of extensors and flexors (H / Q) which is an important detail for the prevention of lower limb injuries Methods: This is an experimental study. The measured research group (n = 12) consisted of the students of the Faculty of Physical Education and Sport at the Charles University. A Black roll foam roller of medium hardness with a non-serrated surface was used. The range of motion of the knee flexors were measured using the sit and reach test and the knee extension test. The range of motion of the knee extensors were measured using a modified Thomas test and Ely's test. The isokinetic strength of the extensors and flexors muscles of the knee joint and the H/Q ratio were measured using a Humac Norm isokinetic dynamometer. Results: Measurements showed that the foam roller affected the range of motion of the flexors and extensors...

Effect of foam roller application on muscle tone after physical load
Patschová, Miroslava ; Lopot, František (advisor) ; Tlapáková, Eva (referee)
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...

Warm up in ice hockey
Arnošt, Daniel ; Jebavý, Radim (advisor) ; Vojta, Zdeněk (referee)
Title: Warming up for ice hockey Objectives: The aim of these bachelor theses is to create a survey about warm up for ice hockey. Based on a survey, study of specialized literature and consultation with selected trainers I suggest a battery of exercises on a selected part of self-myofascial release with selected tools (foam rollers, balls). Methods: For the purpose of this bachelor thesis a quantitative scientific method was used. The data was obtained using the poll method. Data has been embedded in Excel. From these data, tables and charts were created. Results: Players spend longer time before the game than before training. Next results have confirmed that players have knowledge of mobilization, activation and self-myofascial release exercises. They use specific tools - foam rollers, resistance bands and balls. I create a battery of exercises for self-myofascial release. Keywords: ice hockey, warming up, foam roller, mobility, SMR
