Analysis of the technique of performing motor actions using the breaststroke method of highly qualified athletes, participants of the finals of the World Championships and Olympic Games, using the developed classification showed that at a distance of 50 m breaststroke athletes more often use a narrow and short amplitude of rowing with their hands and a narrow amplitude of pushing with their feet. At a distance of 100 m breaststroke athletes almost equally use both wide and narrow amplitudes of strokes with their hands and repulsions with their feet, while the longer amplitude of the stroke with their hands prevails. At a distance of 200 m breaststroke athletes often use a long and wide range of movements with their arms and legs. But during the analysis of swimming techniques at this distance, it was noted that a number of athletes change the amplitude of motor actions at various stages of the distance. So, at the finish line of the 200 m distance, some athletes clearly switched from a wide amplitude of strokes with their hands and feet to a narrower one, thereby increasing the frequency of movements and raising the pace of progress not only by increasing the speed of the stroke, but also by reducing the amplitude of movements.
