Objective of the study is to analyse changes in the coordinates of the athlete's centre of mass during the demonstration of a Mawashi-geri kick, performed both correctly and incorrectly, with the supporting leg not turning.
Methods and structure of the study. The experiment was conducted at the Olympic Reserve Sports School in the Petrodvorets district. During the study, video recordings were made of the athlete performing a Mawashi-geri kick with the right and left legs – a) technically correct and b) without turning the supporting leg. Each kick was performed three times.
Results and conclusions. To describe the movement, the coordinate value ranges (quasi-attractors) of the overall centre of gravity and the centres of gravity of the athlete's body segments were used. In the case of a Mawashi-geri kick performed without turning the foot of the supporting leg, the values of the quasi-attractors of the striking foot are lower than those of a kick performed with the supporting leg turned. The value of the quasi-attractor of the coordinates of the centre of gravity of the striking foot can be used as a criterion for identifying technical errors. The results of the study can be used to correct striking techniques in combat sports.

Keywords: biomechanics, combat sports, Mawashi-geri.
