Performance indicators of highly qualified judokas in weight categories 90 and 100 kg at the World Judo Championships-Doha 2023

Abstract

Purpose: to analyse the indicators of competitive activity of highly skilled judokas of weight categories 90 and 100 kg at the World Judo Championships-Doha 2023. Material and methods. Research methods were used during the work: analysis and generalization of scientific and methodical literature; timing; analysis of protocols and video recordings of fights of highly qualified judokas of weight categories up to 90 and 100 kg; methods of mathematical statistics. We analysed 61 bouts of judokas in the weight category up to 90 kg and 47 meetings of athletes up to 100 kg. Results: the time analysis of the bouts of highly skilled judokas showed that almost half of the bouts ended early. Thus, for athletes under 90 kg, this figure is 45 %, for judokas under 100 kg – 47 %. Accordingly, the number of matches that ended within the allotted time is the smallest: 22 % for athletes under 90 kg and 19 % for judokas under 100 kg. The percentage of bouts that ended in extra time is 33 % in the category up to 90 kg and 28 % up to 100 kg. An analysis of the types of comments received by the competitors showed that the largest number of them in both categories were received for three types of penalties: not fighting (up to 90 kg – 43 % of all comments; up to 100 kg – 40 %), avoiding a grab (up to 90 kg 23 %; up to 100 kg – 10 %) and using false attacks (up to 60 kg – 9 %; up to 100 kg – 24 %). The analysis of the disqualifications of highly qualified judokas showed that out of 61 fights of athletes in the weight category up to 90 kg, 12 (19 %) ended in disqualification. It is interesting to note that 11 fights (92 %) were disqualified for punishment and 1 fight (8 %) for traumatic prohibited actions (head dipping)). In the weight category up to 100 kg, 87 fights were analysed, of which 13 (27 %) ended in disqualification. More than half of them were for penalties - 7 fights (54 %), and 2 fights (15 %) for traumatic prohibited actions (head dipping). There were also disqualifications for doctor's call - 1 fight (8 %) and no-show - 3 fights (23 %). The main effective technical actions, which are most often used by athletes of each weight category separately in the stand, floor position and lying down, were revealed. Thus, in sportsmen of a weight category up to 90 kg these are: a group of throws through a back (13 %), pick-ups  (13 %), hooks (13 %), a throw through a head with a planting of a shin (12 %) and different types of holdings (a lower back - 60 %; from the side of a head - 20 %; from the side with a grip from under a hand - 20 %). In judokas of the weight category up to 100 kg these are: grabs (39 %), hooks (16 %), throws by unbalancing (9 %) and hold across the back (37,5 %). Conclusions. It was established that judokas of weight categories up to 90 and 100 kg finish most of the fights early, during the fight they receive a rather large number of remarks connected with a cautious waiting struggle for which they receive punishment for not conducting a struggle, avoiding a grip. It was found that the struggle of athletes up to 90 and 100 kg mainly takes place in the stance. It has been established that athletes in the weight category up to 90 kg are more technical and use a greater volume of technical actions in competitions. But this applies only to the stance position. If we analyze the position of the floor, lying down, then athletes of the weight category up to 100 kg, on the contrary, have a greater arsenal of technical actions in comparison with the category up to 90 kg.
