Determination of exercise post-oxygen consumption (EPOC) following resistance training, and aerobic exercise
Galertová, Alena ; Petr, Miroslav (advisor) ; Sedlak, Petr (referee)
Oxygen debt repayment after completion of intense muscular activity reflects the significant involvement of anaerobic metabolism druring exercise. Some studies have reported an increased oxygen consumption even after 24 to 48 hours after strength training character, while after the activities of lower intensity (the aerobic exercise) is the oxygen consumption increased only in the order of several hours. In common practice, especially in the selection of the most suitable forms of exercise to increase energy expenditure in the general population, this is not usually a calculated factor. The aim of the thesis is the comparison of the energy expenditure by using indirect calorimetry and monitoring of selected individuals and at intervals after completion intense muscular activity and after aerobic exercise.

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
