Background: Fencing lunge is the most important element of the fencing footwork technique. The aim of this study was to determine the dynamic model of the fencing lunge made by an experienced athlete, based on the EMG record of muscles activity: extensor carpi radialis of the right arm and rectus femoris of lower extremities.
Material/Methods: 31-year-old Magda Mroczkiewicz, the team Olympic vice-champion and the world champion in women’s foil, took part in the research during the preparatory camp for the 2011 season. To assess muscle involvement in the movement the electromyography (EMG) method was used. A device manufactured by NORAXON with MyoResearch XP MT400 software was utilized.
Results: During the fencing lunge, muscle activation starts from the rear lower extremity, then the attacking arm, and finally the front lower extremity. The average EMG stimulation was the largest in the rear lower extremity and the smallest one in the attacking arm.
Conclusions: The research shows that top-class athletes start the fencing lunge from tension in muscles of the rear lower extremity. Moreover, stimulation of the weapon arm and rear lower extremity muscles indicates their synchronization, whereas the front lower extremity works asynchronously
Key words: fencing lunge, EMG signal, movement duration
