Upper limb and trunk strength asymmetry and relationships in young elite soccer players
Haisová, Linda ; Hank, Mikuláš (advisor) ; Kunzmann, Egon (referee)
This diploma thesis aimed to evaluate the level of upper limb strength asymmetry between the dominant and non-dominant side and trunk rotation strength in young soccer players, then to compare this relationship with respect to strength performance. The research population consisted of 18 young players in the U16 age group who play soccer at an elite level. Players participated in isometric upper extremity and trunk strength testing. Data collection of isometric upper limb grip strength (Handgrip) parameters was performed using a digital handheld dynamometer (Takei, A5401, Japan). A Humac Norm Cybex isokinetic dynamometer (CSMi, Humac Norm, USA) in isometric mode was used to test trunk strength in rotation. The results of the trunk rotation force values in favor of the dominant side averaged 19.83 ± 3.47 kg. For the non-dominant side, players achieved average results of 19.17 ± 3.33 kg. The T-test results showed that the dominant side of the body achieved significantly higher results in absolute trunk rotation strength with a value of p = 0.035, also in relative strength with a value of p = 0.032. In the Handgrip, the average result value on the dominant side was found to be 41.76 ± 8.63 kg. The non-dominant side achieved a mean grip strength value of 39.68 ± 5.79 kg. The results of the T-test...

Kočiško, Boris ; Kaplan, Aleš (advisor) ; Hank, Mikuláš (referee)
Thema works: Problematic issue with agility training in football (literary research) Student: Boris Kočiško Supervisor: Doc. PhDr. Aleš Kaplan, Ph.D., MBA. Aims: The aim of the thesis was a literature search, which consists in focusing on the issue of agility in football and mainly observing, trying to record the currently available literature that relates to this issue and noting certain opinions and forming a certain node, which is the most relevant for coaches in this regard. Methodology: In this thesis, the method of literature search was used. While writing this thesis we used analyses of already existing foreign and Czech sources, which we commented with our own opinions. Results: Based on the literature search, an outline of the problem was made supported by other possible approaches, drawing on knowledge and experience from sport, football and agility training in both adult and youth settings. The thesis briefly analysed and then described briefly the issues in agility training. Thirty-two foreign sources and 10 Czech sources were studied, starting mainly from foreign sources as they offer a wider range of perspectives and experiences. We found that agility is a very important component of sport performance in soccer players. We pointed out the differences in different authors, the result...

The acute effect of percusive therapy on postural stability and muscle activation in people with chronic ankle instability and controls
Michal, Lukáš ; Hank, Mikuláš (advisor) ; Šorfová, Monika (referee)
F2 = 0.15; with a significance level of α = 0.05 and a test power of β = - - (p=0.014) CAI NO PRE (CNP) and HEALTHY YES POST (HYPO) and between the CAI NO POST (CNPO) vs. HYPO (p=0.05). The only statistical difference (p=0.045) within CAI group was found in CNP vs. CAI YES POST (CYPO). Since there was no significant difference in the pre-tests between any of the groups (CNP and CYP), we may confirm the hypothesis of the effect of PT in postural stability (OE) test. In contrast, in the CE test, this change was observed between groups CNPO and CYPO (p=0.05). Since there was no pre-test difference between the CAI groups in CE parameter, we may also confirm the effect of PT in CE test, even though the intragroup outcomes between pre and post-test weren't sensitive enough to find significant (p<0.05) improvement. Unilateral postural stability surveyed in relation to PT showed increased bilateral asymmetry between DOM and NON in Flamingo test (expressed as %). Especially HYPO group revealed risen asymmetry after PT when compared to CNPO (p=0.007), CNP (p=0.015) and CYPO (p=0.05). Key finding was measured significant difference in intragroup parameter between HYP vs. HYPO (p=0.014), which confirmed increased bilateral asymmetry in unilateral postural stability HEALTHY subjects before and after use of PT, but not...

Bilateral asymmetry of lower limb strength abilities in young snowboardcross athletes
Bohůnková, Marie ; Hank, Mikuláš (advisor) ; Gnad, Tomáš (referee)
The aim of this diploma thesis was to find out the relationships between the performance of strength skills of the dominant and non-dominant lower limbs with respect to the preferred side of riding in snowboarders of different sexes at the racing level. Elite and sub-elite level snowboarders aged 19.16 ± 4.63 years (11 females and 9 males) participated in testing the isokinetic force in the knee joint and the isometric force in the hip joint. Data collection of isokinetic parameters of flexion strength and extension in the knee joint was performed on a Cybex Humac Norm isokinetic dynamometer (Cybex NORM®, Humac, CA, USA). Collection of isometric parameters of abduction force and adduction in the hip joint was performed by the ForceFrame systémem system (Vald Performance, Australia). The position on the snowboard affected the bilateral asymmetry of force in favor (p <0.05) of the dominant limb (front on the snowboard) in some parameters. The magnitude of the isokinetic force between the dominant and non-dominant limbs differed significantly (p <0.05) at extension in the male group, but not in the female group. Significance difference (p <0.05) was found for flexion only for male group. The dominant lower limb achieved a significantly higher (p <0.05) value of the isometric force of abduction in the...

Analysis of player's movement during the volleyball match
Hank, Mikuláš ; Zahálka, František (advisor) ; Vorálek, Rostislav (referee)
The aim of this study was focused on the quantitative evaluation of movement distance of elite female volleyball players in match, and the comparison between the values of selected players. For the evaluation in the study was used 3D kinematic motion analysis. The observed homogeneous group consisted of elite female volleyball players at CEV Champions League match (n = 14, age = 25 ± 6 years, height = 182.3 ± 6.2 cm, weight = 72.1 ± 5.8 kg). Overal were processed four sets, a total of 167 rallies. The average movement distance of one player evaluated from 167 rallies was 1259.89 meters, the equivalent of one rally was 8.8 m. The average movement distance of Libero in one rally was bigger than the other players' (9.6 m). Results of this study has shown an interindividual differences in final volume of movement distance between group of players that was participating in every rally (spikers, setter, opposite player) and players that were not participating in every rally (libero, blockers). Comparison of average movement distance of players in one rally has shown no significant difference.

Analysis of voleyball players' movement during the match
Hank, Mikuláš ; Zahálka, František (advisor) ; Vorálek, Rostislav (referee)
The primary task of this thesis was to evaluate, quantify and objectify distances of movement of elite volleyball players in terms of individual game specializations in the horizontal plane of motion. Secondarily, these values were mutually compared. For evaluation was used 3D kinematic motion analysis. Analyzed homogeneous group consisted of senior volleyball players at the Champions League level (n = 14; age = 25 ± 6 years; height = 182.3 ± 6.2 cm; weight = 72.1 ± 5.8 kg). Processing were four sets, a total of 167 rallies. The average distance one player absolved for 167 rally was 1259.89 meters in whole game, per rally, this value was 8.8 m. The movement of players was divided by a total of four directions relative to the volleyball net forward, backward, left and right. The results showed a high degree of homogeneity in the external load players and brought objective values for comparison between the players' specializations. Powered by TCPDF (www.tcpdf.org)
