Analysis of overhead throw in baseball
Zelený, Michal ; Süss, Vladimír (advisor) ; Carboch, Jan (referee)
Title: Analysis of overhead throw in baseball Objectives: to describe the work of muscles musculus trapezius dexter, sinister and musculus pectoralis major dexter, sinister during the classic side overhead throw, the throw without using left arm, the front throw, the pitch from the floor and the pitch from the pitching hill using the surface electromyography; to compare all types of the throws and to determine the differences between them Methods: surface elektromyography, video content analysis Results: based on the results of the analysis we can say, that the activity of the chosen muscles during the various types of throws differs in intensity and in the duration of action potencial as well Keywords: baseball, surface elktromyography, overhead throw, throw without using left hand, front throw, pitch

The motion pattern of abduction in the shoulder joint in overhead throwing of softball Extraliga players
Hrdinová, Denisa ; Stupková, Michaela (advisor) ; Nováková, Tereza (referee)
Author: Bc. Denisa Hrdinová Title: The motion pattern of abduction in the shoulder joint in overhead throwing of softball Extraliga players Objectives:The aim of the thesis was to monitor and evaluate the difference in the sequence of tenses of muscle recruitment during the abduction in the shoulder joint between softball players and the general population, using surface electromyography (SEMG). A partial aim was to identify shortened muscle groups of the shoulder girdle and their influence on the timing of the abductors. Another partial aim was to evaluate the effect of shortened muscle groups on possible deficits in scapulohumeral rhythm of softball players. Methods: The experimental group (n=10) and the control group (n=10) with a total average age of 21.8 ± 1.81 (SD) participated in the kinesiological analysis with targeted examination of the shortened muscle groups and scapulohumeral rhythm. Followed by SEMG examination of muscle timing during abduction in the shoulder joint. Five muscles were monitored during 15 repetitions of motion at 70 bpm. The SEMG signal analysis was processed by rectification and smoothing in MyoResearch software by Noraxon v3.80 and statistical analysis performed in program Statistica 13.4. Results: 1. The difference in timing between the experimental and control...
