Muscle activity in sticking region during flat bench press
Kopecký, Václav ; Šťastný, Petr (advisor) ; Petr, Miroslav (referee)
Title: Muscle activity when surpassing the sticking region in the concentric phase of a bench-press Objectives: The aim of this work is to compare muscle activity of prime movers and stabilizing muscles in each region of the concentric phase in a bench- press (pre-sticking, sticking and post-sticking phase). Methods: To get all the necessary data a method of randomized experimental research was used in preset laboratory conditions. Afterward a method of analysis was used for data evaluation. Results: Neuromuscular fatigue had occurred at submaximal (4 RM) loads in the primary movers during the sticking and post-sticking phase. In case of maximal (1 RM) loads the hypothesis was rejected due to that fatigue had occurred later, during post-sticking phase. Furthermore a neuromuscular fatigue of stabilizing muscles during maximal (1 RM) and submaximal (4 RM) loads was found. Keywords: bench-press, sticking region, sticking point, electromyography, EMG, muscle activity, resistance training

The influence of breathing strategy on sticking region during the bench press exercise.
Kolinger, Dominik ; Šťastný, Petr (advisor) ; Petr, Miroslav (referee)
Title: The influence of breathing strategy on sticking region during the bench press exercise. Objectives: The aim of this work is to determine the differences in duration and track that are necessary to overcome the sticking region while using variations of breathing patterns and loads during the bench-press exercise. The next goal is to find out whether the sticking region occurs in the bench-press with resistance of 1 RM, 4 RM, 8 RM and 12 RM. Methods: In this thesis I used a method of experimental research combined with method of analysis. Method of randomized experimental research was aplied during the actual research in preset conditions in the sports laboratory. Later the collected data was analysed and evaluated using specialized software. Results: In the empirical part of this thesis I found out that there are significant changes in duration and track of the sticking region and its parts after modyfying the breathing pattern during bench-pressing with maximal resistance (p<0,05). The Valsalva maneuver proved to be the best breathing technique in relation to overcoming the sticking region. There seem to be no significant changes in the characteristics of the sticking region and its parts while using different breathing patterns and lifting submaximal loads (4 RM) (p>0,05). This study also...

The anthopometric relation to bench press performance and sticking region
Široký, Michal ; Šťastný, Petr (advisor) ; Petr, Miroslav (referee)
Title: The anthopometric relation to bench press performance and sticking region Objectives: The aim of the thesis is to determine the influence of anthropometric parameters on the performance in bench press and its critical phase of motion. Another objective of this work is to determine the differences of influence anthropometry between 1 RM, 4 RM, 8 RM and 12 RM as well as anthropometric impact on the area occurring before the critical phase of motion and on the area after the critical phase of motion. Methods: This is a quantitative research based on the comparison of measured anthropometric parameters with performance and kinematics by bench press analysis. For experimental methods it was used laboratory conditions and it was used methods of analysis to evaluate the acquired data. Results: The results of the work show that anthropometric parameters affect the performance especially at 1 RM and 12 RM. Overall, the forearm has the greatest impact, reaching a strong negative correlation r = -0.69. Lower arm abduction at 12 RM has a large correlation coefficient r = 0.68, and the chest ratio with upper limb length has a mean positive correlation r = 0.55 for 1 RM and 12 RM. The influence of anthropometry on the critical phase of motion has not been confirmed. Only the correlation between...
