The article provides an analysis of the trajectories of the centers of mass of athletes in the process of performing a cut from the inside in the absence of resistance and in a competitive battle. For analysis, videos were taken from the Internet. Each video was divided into frames. On each frame, the centers of mass of body segments were noted, and then the center of mass of each athlete and the system of two athletes were calculated. During the throw under the absence of resistance, the trajectory of the center of mass of the attacking athlete is oscillatory. During the throw under the absence of resistance, the trajectory of the center of mass of the attacking athlete is oscillatory. Preparation of throw is usually absent. The throw is carried out due to one model. When performing a throw in a competitive duel, the character of the attacker's center of mass movement is rotational. The throw in a competitive fight is usually based on a combination of models. Before the throw, the resultant force of the atta
