The influence of specific training on the development of muscle strength of legs
Nepožitek, Jan ; Bátorová, Michaela (referee) ; Šťastný, Jan (advisor)
The bachelor thesis deals with the use of isokinetic dynamometry for the analysis of the effect of specific training. The introductory part of the bachelor thesis described isokinetics, history and types of muscle activities. There is also a proposal for a specific training, which the experimental group followed over the course of two months. Part of the work is to determine the measurement methodology on an isokinetics dynamometer, in which the experimental and control groups were measured before and after specific training. As part of the dynamometric testing, the muscular strength of the lower limbs in the knee joint was measured, in which the quadriceps and hind muscles were the most involved. The assumpiton was that experimental group would have an increase in muscle strength after completing a specific training. The measured values were processed in the Matlab software environment, thanks to which the individual signals and the maximum values of individual measurements were plotted. The measured values were statistically processed and evaluated using non-parametric tests. It was found that specific training had a partial effect on the development of muscle strength in the lower limbs.

The relationship between strength ratios of hip abductors, adductors, internal, external rotators and speed of shouting in ice hockey players
Hučko, Petr ; Šťastný, Petr (advisor) ; Vojta, Zdeněk (referee)
Title: Relation between power ratios of adductors, abductors, external and internal hip rotators at shooting speed of ice hockey players Objectives: The main aim of this thesis is to find out the relationship between the rate of fire on the ice and the strength abilities of the hand and hip rotators Methods: The research group consisted of 20 adult probands (age = 24.8 ± 3.4; height = 181 cm ± 6.13 cm; weight = 80.1 kg ± 9.9 kg). The research took place in the summer preparation period after the season. The laboratory tests were carried out at the Charles University FTVS under the supervision of qualified and trained experts. An isokinetic dynamometer (Cybex NORM ®, Humac, CA, USA) was used to test external and internal rotators. A hand isometric dynamometer (Takei 5401) was used to evaluate the handgrip. Field tests were conducted on the ice, where the rate of fire was recorded using radar (V-max). Results: The results showed a significant degree of association between SBN and SVN shooting and rotator force at concentric contraction (30ř∙s-1 , 90ř∙s-1 ) for the dominant leg, reaching values (r = 0.45) for the angular velocity of 30ř∙s-1 and at higher angular velocities it assumed values (r = 0.44 and 0.54). Statistical analyzes also showed a significant degree of association between SVN-firing and...
