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.

Cardan/Euler angles represent the most common technique for the quantification of segmental rotations. Cardan angles are influenced by their ordered sequence, and sensitive to planar-cross talk from the dominant rotation plane, which may affect the angular parameters. The International Society of Biomechanics (ISB) currently recommends a sagittal, coronal, and then transverse (XYZ) ordered sequence, although it has been proposed that when quantifying non-sagittal rotations this may not be the most appropriate technique. This study examined the influence of the helical and six available Cardan sequences on lower extremity three-dimensional (3-D) kinematics of the lead leg during the fencing lunge. Kinematic data were obtained using a 3-D motion capture system as participants completed simulated lunges. Repeated measures ANOVAs were used to compare discrete kinematic parameters, and intraclass correlations were also utilized to determine evidence of planar crosstalk. The results indicate that in all three planes of rotation, peak angle and range of motion angles using the YXZ and ZXY sequences were significantly greater than the other sequences. It was also noted that the utilization of the YXZ and ZXY sequences was associated with the strongest correlations from the sagittal plane, and the XYZ sequence was found habitually to be associated with the lowest correlations. It appears that for accurate representation of 3-D kinematics of the lead leg during the fencing lunge, the XYZ sequence is the most appropriate and as such its continued utilization is encouraged.
