The utilization of isokinetic dynamometer for the measurement and evaluation of muscle strength of lower limbs in athletes
Přidalová, Tereza ; Janoušek, Oto (referee) ; Chlíbková, Daniela (advisor)
Izokinetická dynamometrie je moderní metodou pro hodnocení svalové síly. Nejvíce se využívá pro posouzení tréninkového efektu během určitého období a pro rehabilitační účely. Kliničtí lékaři, vědci a fyzioterapeuti obvykle využívají pouze základních parametrů pro vyhodnocení svalové síly. Cílem této práce je tedy navrhnout alternativní přístup pro interpretaci dat a předložit možné využití a limitace této metody. Byl měřen moment síly v kolenním kloubu a následně provedena datová analýza. Patnáct parametrů je využito pro vyhodnocení dat. Moment síly byl porovnán mezi profesionálními sportovci (muži: 111.1 ± 51.0 [Nm/kg], ženy: 99.6 ± 90.8 [Nm/kg]) a amatérskými sportovci (muži: 146.2 ± 40.1 [Nm/kg], ženy: 45.3 ± 14.6 [Nm/kg]). Vztah byl pozorován mezi parametry úhlové pozice maxima a dobou od dosažení maxima do konce pohybu (flexe: = 0.65, extenze: = 0.71) a mezi úhlovou pozicí maxima a poměrem vykonané práce před maximem (flexe: = 0.91 extenze: = 0.86). Parametr práce v submaximální oblasti byl vyšší pro extenzi (median= 3.0 J) než pro flexi (median= 2.6 J).

Synchronization and practical use of isokinetic dynamometer with surface electromyography unit
Špaková, Adriána ; Hanák, Petr (referee) ; Šťastný, Jan (advisor)
The bachelor's thesis deals with a design proposal for the solution of synchronization of an isokinetic dynamometer with a surface electromyography unit, and subsequently performs the realization of their synchronization. These devices are used as diagnostic and therapeutic medical technique and in practice are standardly used separately. It is expected that by using them simultaneously would be possible to obtain more detailed information about the condition of the examined individual. Synchronized devices can thus be useful, for example, for the analysis of muscle performance of patients with neuromuscular diseases or athletes who want to improve their quality of life after suffering an injury or plan comeback to their favourite activity. After successful synchronization, the work is focused on testing the muscle activity of flexors and extensors of the knee joint of athletes. Measurements were performed on healthy subjects as well as those who had suffered knee injuries in the past. The measured signals were processed, and the measurement results were interpreted. The work includes the elaboration of all the goals based on its assignment, including the main idea of the work, what is the successful synchronization of the isokinetic dynamometer with the surface electromyography unit and their practical use.

Diagnosis and analysis of lower limb muscles of acrobatic rock and roll dancers
Palivcová, Nikola ; Kozáková, Alena (advisor) ; Kolbová, Kateřina (referee)
Title: Diagnosis and Analysis of Lower Limb Muscles in Acrobatic Rock and Roll Dancers Objectives: The aim of the thesis is to determine the occurence of possible muscle imbalances, lateral and functional asymmetries in acrobatic rock and roll dancers which may be caused by unilateral loading in this sport and based on diagnostics and training recommendations to prevent the risk of injury or damage the musculoskeletal system. Methods: The final thesis is processed as an observational case study and the project is implemented as quantitative research using paired comparison. The results are statistically processed and interpreted using descriptive analysis. The main method of measurement is isokinetic dynamometry on the Humac Norm Dynamometer. Results: Based on the individual measurement results and the subsequent statistical evaluation of the data, the research question is answered: "Due to unilateral loading in acrobatic rock and roll dancers muscle imbalances and lateral and functional asymmetries in the muscles of the lower limbs arise." At the beginning of the research three hypotheses were established, first was confirmed, the lowest flexion-extension symmetry was 17 % in the left limb. The second hypothesis was also confirmed, the highest extension value of the left limb was 171 Nm, while the...

The comparison and identification of strength abilities among elite footballers depending on ontogenesis
Kroupa, Jakub ; Malý, Tomáš (advisor) ; Kokštejn, Jakub (referee)
Title: The comparison and identification of strength abilities among elite footballers depending on ontogenesis. Objectives: The aim of this work is to compare the explosive power of the lower limbs and the isokinetic power of the knee extensor and knee flexor of elite football players in cathegories U16, U18 and U21 of the club SK Slavia Praha. Method: Our work is based on using the comparative method. The respective method of comparison is used in the section related to results., in which we compare the achieved strenght abilities of each category in the vertical jump tests and the isokinetic dynamometer tests. The research team were young players (n46) from three age-old categories U16 (15 players), U19 (17 players) and U21 (14 players). The results: The result of the study is a finding that the performance of the individual categories in the vertical jump tests within the maximum power achieved is very balanced, but the best average results in the maximum height were found at U21 team. The order of the individual categories is not the same as the maximum height achieved in the vertical jump. Another finding is that for U21 players compared to younger categories, we observe weaker achievements with greater performance differences between between the muscle groups of flexor and the knee...
