A CASE STUDY OF THE KICKING FOOT AND STANCE IN ROUNDHOUSE KICK: CONTROL AND COMBAT SITUATIONS

Once this work is part of a long term study, the aim was to show the preliminary results of the comparison of the kicking foot and stance in the roundhouse kick according to the onset condition (control vs. combat situation). One black belt athlete participated on this study. A motion capture system of 18 cameras (Optitrack© 360Hz) was used for the kinematic data acquisition. In order to obtain the maximum height and speed, execution and movement time of the kicking foot we used one marker. In order to represent the stance positions we used five markers. The preliminary analyses suggest that there are differences between control and combat situations: 1.the maximum height was smaller in combat situation since the athlete prefers to kick in the trunk of the opponent and 2.the stance positions highlight the influence of the movements of the opponent in combat
