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...

Influence of specific exercises on bladder fixators of older school-age swimmers
Šaroch, Michal ; Jurák, Daniel (advisor) ; Pánek, David (referee)
Objectives: The aim of this thesis is find out the effect of the intervention compensatory exercise on the function of scapula fixators in older school-age swimmers. Methods: This is a one-factor experiment in which the activity of the scapula fixators will be evaluated by Jandas push-up stereotype, Kolars tilt test and swimming breaststroke. The activity was evaluated by 4 evaluators for observing objectivity. After the first initial evaluation, 8 weeks of interventional compensatory exercise will be started, which will include 9 specific exercises for strengthening scapula fixators. At the end of the experiment, the above tests are again performed to evaluate the activity of the blade fixators. Results: The results showed a significant weakening of the scapula fixators in 97. 14% of the tested elderly-school swimmers at the start of the experiment. After 8 weeks of interventional compensatory exercise, focusing on scapula fixators, the weakening was only present in 11. 43% of swimmers. Key words: Swimming, scapula fixators, elderly school age, compensatory exercise
