Introduction

1. Introduction • The following presentation is a brief description of judo and a small insight into elite level Judo techniques commonly used. • We looked at the difference in the range of techniques of different weight categories, recorded the key information that allowed us to see what techniques are the most common among an elite level judo player (Judoka). • Once we had all the information it was just down to planning how to present the information to our audience who would predominantly be non-judo people.

2. Competition Judo When fighting in a judo competition it is physically demanding on the body and mind because the sport is not a passive sport, it is fast paced which means a judo bout can end in a couple of seconds. At lower levels of judo, players are expected to compete in a white Judo Gi and also wear either a blue or white belt so referees know who to award points scored to, similar to a blue and red corner in a boxing match. However at higher levels of the sport judo player are expected to compete in either a white or blue suit as the action can be even faster paced and also helps if the action is televised.

3. Aims Of A Judo Bout • Two Players attempt to throw each other flat on their back by many different types and ranges of techniques and if not performed properly can result the attacking player becoming at risk from an opponents counter attack. • Grappling on the floor, players will also attempt to hold their opponent down (pin) or make them submit by arm lock or strangulation/choke. Dependant on how well a player performs their throw on an opponent, will depend what score will be awarded by the referee.

4. Scoring system • A score is given dependant on the position a player is thrown to the ground encompassing speed and force. • Points are then given to the player completing the throw.10, 7 , 5 or 3 point scores are awarded. • 10 points being a full score (Ippon) which will end a match.7 points (Wazari) bout continues 5 points (Yuko) bout continues3 points (Koka)bout continues • Specific hand signals are given by the refereeto show score awarded and for table officials to record scores. • The player at the end of the match who has the highest value scoring throw is announced the winner, points are not cumulative.

5. Refereeing • During a bout there are 3 referees, one in the middle interacting with the players and another two in opposing corners to assist the main referee on contentious issues. • Referees award the points for throws and also watch out for illegal actions within the fight. • If an illegal action is given the player is given a penalty (Shido) and the other player is given points. • If needed the referee can also remove a player from competition for illegal or dangerous actions.

6. Where did we gather our information from? Video footage from the 2003 Judo World championships, Osaka Japan. What did we analyse in particular: • Scoring throws only • The range of techniques used • What throws were the most commonly used • A focus on the five core techniques that we have been studying in training

7. The 5 core techniques O-Soto Gari (Large outer reaping) Ippon Seoi-nage (One arm shoulder Throw) Uchi Mata (Inner Thigh Throw) O-Uchi Gari (Large inner reaping) Tai O-toshi (Body Drop)

8. The graph below indicates the range of techniques used in the Video footage by World class Judoka, as you can see the results show that the 5 core techniques we are working on feature highly at this level of competition.

9. Results of our analysis. • The 5 core techniques featured most commonly during the championships. • We found that a low percent of judo was used on the ground as time was not given by the referee. • Surprisingly 22% of the chart was allocated to leg grab/ Kata Guruma style techniques. This was most likely due to the influence of Russian / old eastern block countries competing in the event which highlighted the difference in styles of Judo.
