Local and global effect of sub-maximal squat on post-activation enhancement of muscle power output
Kolinger, Dominik ; Šťastný, Petr (advisor) ; Hojka, Vladimír (referee)
Title: Local and global effect of sub-maximal squat on post-activation enhancement of muscle power output. Objectives: The aim of this thesis is to determine whether the phenomenon of post-activation performance enhancement (PAPE) manifests locally or globally in terms of improved muscle power output. That is, to determine whether activation of a complex muscle chain will lead to improvements in the muscle power output of other muscle groups and muscle groups included in the activated muscle chain. In this way, to indicate the relationship between global and local physiological mechanisms causing PAPE. Methods: The quasi-experimental method and the method of analysis were used in this work. Eleven basketball players aged 18-28 years completed two measurements in random order. The measurements started with a non-specific warm-up followed by a pre- activation test (pre-CA) to obtain baseline values. Next, the players performed a specific warm-up and activation exercise (CA) in the form of a squat with an intensity of 2 × 4 × 90 % of one repetition maximum (OM) with a rest interval of 3 min. After the activation exercise, post-CA values were measured at minutes 5, 8 and 11 on force plates and at minutes 6, 9 and 12 on an isokinetic dynamometer (IKD). Pre-CA and post-CA test of the protocol one...

Power tonisation in women's softball
Pfeifer, Jan ; Jebavý, Radim (advisor) ; Feher, Jan (referee)
Title: The force toning in women's softball Objectives: The aim of this study was to demonstrate post-activation potentiation (PAP) following the muscle toning during the strenght training. The toning effect on upper limb explosive force was analyzed following application of two different degrees of resistence. Methods: In this study, we applied randomized selection for the subject to minimize the effect of possible ambiguities such as gender, training status, and player maturity. A homo- -geneous group of well-trained women with the most developed technical response was accepted. (Czech national team, Women's softball). We used the contrast method, where the data were analyzed to determine the effect of different resistance degrees and a fixed rest interval for the strength-dynamic exercise. It is a sticking out of medicine ball in sitting position, which was performed by women of the highest player level. The measurement was processed by using the direct method of dynamic efforts. We compared the explosive force with a medicine ball sticking forward in relation to the distance of the sticking medicine ball by the tested person. Results: The measurement has shown that the PAP generated by toning protocol has a sig- -nificant impact on enhancing the response in explosive drills. The exercise for...

Effect of toning in warm-up on performance of floorball players
Králíčková, Kateřina ; Jebavý, Radim (advisor) ; Dragounová, Zuzana (referee)
Title: Effect of toning in warm-up on performance of floorball players Objectives: Find out the influence of toning in warm-up before performance in exercises aimed at determining the action speed, explosive power of legs and agility of floorball players. Methods: A total of 20 floorball player aged 17 - 27 years participated in two measurements, one week apart. On the test day each proband passed one of two types of warm-up, non-toning warm-up and toning warm-up, and the next test day passed the second type of warm-up. The warm-up was follwed by three tests, the 20 m run, the jump from place and the shuttle run. For analysis of results was used statistics methods. Results: The first hypothesis was confirmed for the group of probands aged 17-19 years in the overall performance, 10 m run, 20 m run and jump from place. The second hypothesis was confirmed in the overall performance for all probands, then for the group of probands aged 17-19 years and for the group of probands aged 20-24 years. The second hypothesis was confirmed in the 10 and 20 m run for all probands, in the 10 m, 20 m run and in the jump from the place for the group of probands aged 17-19 years, in the 10 and 20 m run for group of probands aged 20-24 years. According to Cohen's d the results of the 10 and 20 m run were the most...

Post-activation potentiation (PAP) phenomenon - review and experimental verification
Horák, Jan ; Hojka, Vladimír (advisor) ; Červinka, Pavel (referee)
Title: Post-activation potentiation (PAP) phenomenon - review and experimental verification Objectives: Firstly, to compile the systematic review of up-to-date literature. Secondly, to develop method using force platform that will be applicable for PAP measurment during the counter-movement jump. Thirdly, to verify PAP by using the developed method in small group of volunteers. Methods: Review part of the thesis was complied according to analysis of up-to-date literature accessible from Charles University electronic system. The data from the analysis were used to develop method for measurment of PAP by using the force platform (Kistler) and activation of PAP phenomenon by series of squats with specific weight. The peak force and rate of force developement were the monitored parameters. This method was applied on a group of volunteers. Results: Results of experimental part of the thesis showed significant changes in monitored parameters and this change is consistent with current literature. Keywords: post-activation potentiation, peak force, rate of force developement, force platform
