The Effect of Intermittent Compression Therapy on Muscle Fatigue in Soccer Players
Farová, Michaela ; Vomáčková, Helena (advisor) ; Kučerová, Ilona (referee)
Title: Effect of intermittent compression on muscle fatigue in football players Objectives: The first aim was to determine if and what effect of compression intermittent and cryo-compression intermittent therapy has on muscle fatigue parameters in soccer players. The second aim was to elucidate whether one of the interventions could be described as more effective for player's recovery (reduction of muscle fatigue). Methods: This pilot study was designed to clarify whether compression intermittently affects muscle fatigue parameters and to compare the effect of each intervention with each other. Data collection was conducted on a research cohort of 21 soccer players ranging in age from 18 to 22 years with a mean age of 19.8 ± 1.33 years, height 176.1 ± 3.6 cm, weight 72.8 ± 4 kg, and BMI 23.5 ± 1.3 kg/m2 . Ten probands were from the U19 team, seven from the men's B team and four players from the men's A team. In total, the probands were divided into three groups, control, compression and cryo- compression (n=7,7,7). The monitored variable was the height of the Counter Movement Jump at different time points in this pilot study. Data were measured using OptoJump Next. Muscle fatigue at 24 hours after the intervention was assessed based on the differences in CMJ height of each proband, and the...

Evaluation of upper limb muscle fatigue
Netopil, Ondřej ; Janoušek, Oto (referee) ; Horáková, Pavla (advisor)
This work deals with the evaluation of upper limb muscle fatigue by analyzing the signal of surface electromyography. It briefly describes the human muscle of anatomical and physiological point of view. There is also described a mechanism of symptoms of muscle fatigue. The work devots to electromyography, electromyography signal processing and evaluation of muscle fatigue using electromyography. The aim is to evaluate muscle fatigue in trained and untrained person depending on gender and depending on the size of the load, which is proportional to each volunteer separately. The measurement is performed on twelve young volunteers. For measurement is used the Biopac system. The magnitude is determined using a dynamometer. The results of this work show that the most tired are untrained men, then untrained women, then trained men and at least tired are the trained women.

Regeneration in top volleyball players
Fikar, Martin ; Vorálek, Rostislav (advisor) ; Petružela, Jan (referee)
Title: Regeneration for elite volleyball players Objectives: The aim of my bachelor's thesis is to detect the knowledge and awareness of the types of regeneration in volleyball among the clubs of the Czech "UNIQA extraleague". Whether the players comply with these regeneration procedures and to what extent they fulfill these procedures in comparison to findings from the specialized literature. Methods: In my work, i used the questionnaire survey method. The questions for this questionnaire were consulted in advance with an expert in this topic. To make it easier for foreign players, the questionnaire was also written in English. We then compared the results from the questionnaire with professional literature. Results: I found out that regeneration is not given as much emphasis as it should be. At the same time, a high number of accidents surfaced. Another finding concerned coaches who provided inaccurate information regarding passive recovery. Regarding passive regeneration according to players, it is of great importance, but more than half do not do anything that could make this regeneration more effective and of better quality. Keywords: analysis, sleep, performance, muscle soreness, volleyball

The effect of muscle relaxation time during intermittent isometric contractions on finger flexors oxygenation
Fílová, Veronika ; Baláš, Jiří (advisor) ; Vomáčková, Helena (referee)
Author: Bc. Veronika Fílová Supervisor: doc. Jiří Baláš, Ph.D. Title: The effect of muscle relaxation time during intermittent isometric contractions on finger flexors oxygenation Objectives: The main aim of this thesis is to evaluate the effect of recovery time during intermittent isometric contractions of the finger flexors on the overall performance and oxygenation of the flexor digitorum profundus muscle in climbers of different performance categories. Methods: 27 climbers were divided into two groups according to current climbing performance (red point (RP) more and less than 7 on the Union Internationale des Associations d'Alpinisme (UIAA) scale). Group No. 1 consisted of 7 men and 6 women with an average performance of 5+/6- on the UIAA scale with an average climbing experience of 4.2 years. Group No. 2 consisted of 7 women and 7 men with an average performance of 8- on the UIAA scale with an average climbing experience of 11.2 years. All climbers completed 4 measurements on a 1D-SAC (Spacelab, Sofia, Bulgaria) climbing dynamometer with simultaneous data measurement using Portamon (Artinis Medical Systems, Einsteinweg, Netherlands) near-infrared spectroscopy (NIRS). During the first visit, the maximal voluntary contraction (MVC) of the finger flexors and the sustained contraction of the...

Electromyographic Analysis of the Different Handlebars Grips Effect on the Shoulder Blade Fixators
Hrdlička, Vít ; Pánek, David (advisor) ; Pavlů, Dagmar (referee)
Title: Electromyographic Analysis of the Different Handlebars Grips Effect on the Shoulder Blade Fixators Aims: The main objective of this thesis is to carry out a methodological study on the impact of different handlebars grips on the shoulder blades fixators. Result of the grip change is not only reduction of the upper fixators activity and the increase in the lower fixators activity but also co-contraction index increase and muscle fatigue reduction. Based on the hypothesis we assumed that the highest activity rate of the lower blades fixators and the lowest activity rate of the upper blades fixators will be during the handlebars brakes grip. The highest co- contraction index will occur during the handlebar brakes grip and the maximum muscular fatigue will occur during the grip at the top of the handlebars. The first part of the thesis is focused on the literature search and facts retrieval pertaining to the studied issue. In the second special part of the thesis we conducted a research during which the muscle activity of the upper and lower blade fixators was recorded. Three different handlebars grips were considered during the measurement using the cycle ergometer. Methods: Muscle activity was scanned and recorded using surface EMG. Maximal voluntary contraction of selected muscles based on...
