The article considers findings of an experiment to clarify and perfect the o-soto-gari throw technique applied in training process versus that in competitive bouts. To obtain basic data for the experiment, we analysed video replays of top-ranking competitions and exemplary performance records of the o-soto-gari throw technique by highly-skilled martial artists available at, plus video records of the 18-23 years-old male athletes, with the video record analysed at the replay rate of 0.25 of the standard one. The snapshots of the opponents’ support foot hooking moments were cut out by Print Screen command and processed by the Paintbrash toolkit. The body control angles were modelled by the straight line followed by the relevant geometric plotting to model the opponent’s body positions by a hypotenuse of a right-angled triangle. Ratios of the sides and angles of the right triangle were used to compute the body angle on every snapshot. It was found that the body bending angle in the competitive bouts was meaningfully higher than in the training bouts with standing throws. This regularity may be interpreted as indicative of the role of the attacking fighter’s body centre of gravity (BSG) control in a real competitive bout. In this context we offer special sets of exercises that need to be introduced in the education and training process to develop the BSG control skills. The study data and analyses may be beneficial for the martial artists, coaches and sport researchers active in martial arts.
