Objective. To perform biomechanical analysis and to assess the peculiarities of static dynamic stability of the body in athletes of different qualification who perform motor actions in unexpected and rapidly changing situations (based on the materials of hand-to-hand combat). Methods. Analysis of specialized scientific and methodological literature; biomechanical analysis of human body movements using the system of 3D kinematic analysis "Qualisys" and synchronized force platform "Kistler"; methods of mathematical statistics. Results. The biomechanics of static dynamic stability of the body was studied during execution of motor tasks in unexpected situations of hand-to-hand combat. A series of strikes performed by highly qualifi ed athletes is characterized by a rational distribution of the fighter's efforts in the direction of the strike with the appropriate minimization of lateral movements and vertical displacements of the body center of gravity. The motor actions are accompanied by the rapid stabilization of the body between the phases of strike movements and, especially, in the final stage, that allows the fighter to promptly make subsequent decisions and translate them into the required motor actions, which are appropriate to the changing conditions. The data of measurements indicated a high level of static dynamic stability of the body. Achievement of model values of motor actions of the fi ghters is associated with the development and the use of special local programs for the development and improvement of the "motor field" as a basis for technical preparation and technical preparedness of athletes. Conclusion. Maintenance of static dynamic stability when executing motor actions in unexpected and constantly changing situations is associated with the use of special training programs focused on expanding and deepening the motor memory and the “motor field” as the most important components of the athletes' technical preparedness.
