World Ranking List (IJF)
World Ranking List (IJF)
Starting date 1st January 2009
The IJF is introducing a World Ranking List (WRL) in order to identify the leading athletes in each Olympic weight category. It will be used for seeding purposes as well as for Olympic Games Qualification
The World Ranking List will consist of points from the World Cups, Grand Prix, Grand Slam, Masters, Continental Championships, World Championships and Olympic Games:
The Ranking:
The total of ranking points for each player will amount to the sum of his/her five highest point scoresU during each 12 month period:
- look back 12 months from today - five best results count 100%
- look back 13-24 months, from there - five best results count 75%
- look back 25-36 months, from there - five best results count 50%
- look back 37-48 months, from there - five best results count 25%
Additional Rules:
In case of equality of total points, the higher ranking will be decided by:
- The highest sum of the current points from all World Championships.
- The highest current points from one single event, then, if needed, the second highest, and so on
- If the competitors are still equal the decision will be taken by the IJF Executive Committee in case of Olympic Qualification.

Judo to start world rankings
Judo to start world rankings
The International Judo Federation has greenlighted the launch of a world ranking system that will also determine qualifying for the Olympic Games, according to the Yomiuri Shimbun.
Based on points won from the world championship and a new Grand Prix series that will kick off in January 2009, the IJF will award an Olympic berth to the top 20 of each weight class.
The decision was made at a board meeting in Bangkok on Sunday, and details will be finalized at the IJF extraordinary congress on Tuesday.
The Grand Prix series will be made up of world judo's major tournaments such as the Paris international in February and the Kano Cup at Tokyo in December. The IJF will grade the events on a scale of four to determine the point value of each tournament.
Points from the Grand Prix, combined with the results from the world championships, will determine the rank of each judoka.
The top 20 wrestlers of each weight category--but only one from any single country--automatically qualify for the Olympics.
The IJF also made a rule change Sunday, deciding to scrap the koka point from the judging.
Without koka, the federation anticipates a rise in the number of bouts ending in extra time on the golden point rule. As a countermeasure to the expected increase, the IJF slashed the length of extra time from five minutes to three.
The slew of changes arrives under the gaze of IJF president Marius Vizer, who is seeking to further commercialize the sport.
Beginning with the next election five years away, the IJF president will be allowed to nominate a majority of the board, which would strengthen Vizer's grip on world judo.

Energy demands during a judo match and recovery
Energy demands during a judo match and recovery.
F Degoutte, P Jouanel, E Filaire, Unité Formation Recherche Sciences Techniques des APS, Villeurbanne, France. Br. J. Sports Med. 2003;37;245-249
Objective: To assess energy demand during a judo match and the kinetics of recovery by measuring the metabolites of the oxypurine cascade, lipolytic activity, and glycolytic pathway.
Methods: Venous blood samples were taken from 16 national judoists (mean (SEM) age 18.4 (1.6) years), before (T1) and three minutes (T2), one hour (T3), and 24 hours (T4) after a match. A seven day diet record was used to evaluate nutrient intake.
Results: Nutrient analysis indicated that these athletes followed a low carbohydrate diet. Plasma lactate concentration had increased to 12.3 (1.8) mmol/l at the end of the match. An increase in the levels of extracellular markers of muscle adenine nucleotide catabolism, urea, and creatinine was observed at T2, while uric acid levels remained unchanged. High concentrations of urea persisted for 24 hours during the recovery period. Ammonia, hypoxanthine, xanthine, and creatinine returned to control levels within the 24 hour recovery period. Uric acid concentrations rose from T3 and had not returned to baseline 24 hours after the match. The levels of triglycerides, glycerol, and free fatty acids had increased significantly (p<0.05) after the match (T2) but returned to baseline values within 24 hours. Concentrations of high density lipoprotein cholesterol and total cholesterol were significantly increased after the match.
Conclusions: These results show that a judo match induces both protein and lipid metabolism. Carbohydrate availability, training adaptation, and metabolic stress may explain the requirement for these types of metabolism.

New judging in judo ?
New judging in judo ?
The International Judo Federation is considering a simplification of its judging criteria.To optimize public understanding and make judo more attractive to a larger audience the IJF may remove the terms waza-ari and koka from the international judo lexicon.
The All Japan Judo Federation states “We cannot agree to this if it means the essence of judo will change,” We must first have people understand the principles of judo such as why waza-ari is different from ippon.”
Up till now, four ranks of scoring for throws–ippon, waza-ari, yuko and koka–are used in international matches, but judoka and officials from the European Judo Union and other bodies have expressed dissatisfaction with the current rules, claiming that the “judging concept is abstract.”
Throws are judged on four technical categories including speed and force. An ippon requires an opponent to be thrown on his back with considerable speed and force.
When one element of a throw is missing a waza-ari is awarded, according to the IJF referee rules.
When two are missing, a yuko should be given. A koka is to be awarded “when the contestant with control throws the other contestant onto one shoulder, or the thigh, or buttocks with speed and force,” according to IJF rules.
Discussions on the matter are still taking place within the IJF, but a proposal has been made to remove waza-ari, leaving ippon and yuko, which are easy for referees to distinguish.
“Japan has to be well prepared for an ideological debate and argue its case,” a source connected with the IJF said.

A Comparative Study of Throwing Speed
A COMPARATIVE STUDY OF THROWING SPEED BETWEEN HEAVIER AND LIGHTER CATEGORIES IN JUDO.
Ramdane Almansba - r.almansba@yahoo.fr
Laboratory of Sport and Health, Faculty of Sciences Sport and Physical Education, France.
The aim of this work was to verify if there was a difference in throwing speed performance between heavier and lighter weight categories in judo. Sixteen judoists aged 18±3 years-old, eight considered in the light weight category (-73 kg) and eight considered in the heavy weight category (+73 kg) participated in the study. A force/velocity test was used to determine the anaerobic power, strength, and pedal speed for each subject. Three trials of Nage-komi exercise, each comprised of 15s sets of Osoto-gari, Uchi-mata and Ippon-seoi-nage throws were performed by each subject to ascertain throwing speed. Throws within the sets were intersected by one period of 3 minute passive rest while the trials were separated by one period of 10 minute passive rest. Heart rate and the greatest number of throws within each set were measured for three trials.
We used an ANOVA to compare the number of throws between the two weight categories and a "Student" test when the difference was significant. A correlation was used to examine the link between the different parameters.
Results show that in the force/velocity test pedal speed did not differ between the two categories. However, there was a significant difference between the two categories when throwing speed was measured by the number of throws executed during the Ippon-seoi-nage and Uchi-mata, but there was no significant difference between the two categories for Osoto-gari.
Our study showed that the throwing speed of judoists represented by number of throws appears to be significantly different between the two categories. The lighter category has more speed than the heavier category using arm technique (Ippon-seoi-nage), while the heavier category has more speed using leg technique with half turn of the attacker's body (Uchi-mata). As a result, throwing speed is related to the type of technique used and not weight category.

Sixteen judoists aged 18±3 years-old, eight considered in the light weight category (-73 kg) and eight considered in the heavy weight category (+73 kg) participated in the study. A force/velocity test was used to determine the anaerobic power, strength, and pedal speed for each subject. Three trials of Nage-komi exercise, each comprised of 15s sets of Osoto-gari, Uchi-mata and Ippon-seoi-nage throws were performed by each subject to ascertain throwing speed. Throws within the sets were intersected by one period of 3 minute passive rest while the trials were separated by one period of 10 minute passive rest. Heart rate and the greatest number of throws within each set were measured for three trials.
We used an ANOVA to compare the number of throws between the two weight categories and a "Student" test when the difference was significant. A correlation was used to examine the link between the different parameters.
Results show that in the force/velocity test pedal speed did not differ between the two categories. However, there was a significant difference between the two categories when throwing speed was measured by the number of throws executed during the Ippon-seoi-nage and Uchi-mata, but there was no significant difference between the two categories for Osoto-gari.
Our study showed that the throwing speed of judoists represented by number of throws appears to be significantly different between the two categories. The lighter category has more speed than the heavier category using arm technique (Ippon-seoi-nage), while the heavier category has more speed using leg technique with half turn of the attacker's body (Uchi-mata). As a result, throwing speed is related to the type of technique used and not weight category.

Effects of Judo Kata Practice on Cardiorespiratory Health
EFFECTS OF RECREATIONAL AND COMPETITIVE JUDO KATA PRACTICE ON CARDIORESPIRATORY HEALTH AS EVALUATED BY A PORTABLE GAS ANALYZER SYSTEM. A PILOT STUDY
Carl De Crée, prof.cdcree@earthlink.net , IGER
The last couple of years there is an increased interest in judo kata practice, triggered by the introduction of kata contests at an international level. Various physiological and psychological scientific studies have focused on karate kata, but virtually no addition has been paid by the medical literature to the cardiopulmonary or other effects or requirements of judo kata practice. The purpose of this study was: (1)to gain initial cardiorespiratory data in both recreational and competitive judo kata players, and (2) to test the suitability of the Jaeger Oxycon Mobile™ portable gas analyzer system in similar studies. Twentyfour male subjects participated in this tests. Judo kata are standardized formal choreographic exercises, of which commonly 7 different exercises are practiced, usually in couple. Sei-ryoku zen’yo kokumin taiiku was not included because of its various solo components. Each kata was tested, though not all subjects were able to perform all kata given the highly advanced level required to suitably perform the two ultimate kata. Cardiorespiratory data were obtained by using a Jaeger Oxycon Mobile™ portable gas analyzer system, while blood lactate was determined by use of a portable lactate analyzer. Results showed that kata practice is an excellent aerobic exercise, of which the low injury component makes it suitable for judo practitioners of all ages. Considerable differences in energy expenditure exist between performers despite the standardization. We suggest that the level of experience as well as self-determined pace,intensity and type of kata are responsible for these results. Portable gas and lactate analyzers are suitable instruments to study the cardiorespiratory needs of judo kata practice.

Abstract
Objective: To determine the acute injury profile in each of six sports and compare the injury rates between the sports.
Design: Analysis of national sports injury insurance registry data.
Setting: Finland during 1987-91.
Subjects: 621691 person years of exposure among participants in soccer, ice hockey, volleyball, basketball, judo, or karate.
Main outcome measures: Acute sports injuries requiring medical treatment and reported to the insurance company on structured forms by the patients and their doctors.
Results: 54186 sports injuries were recorded. Injury rates were low in athletes aged under 15, while 20-24 year olds had the highest rates. Differences in injury rates between the sports were minor in this adult age group. Overall injury rates were higher in sports entailing more frequent and powerful body contact. Each sport had a specific injury profile. Fractures and dental injuries were most common in ice hockey and karate and least frequent in volleyball. Knee injuries were the most common cause of permanent disability.
Conclusions: Based on the defined injury profiles in the different sports it is recommended that sports specific preventive measures should be employed to decrease the number of violent contacts between athletes, including improved game rules supported by careful refereeing. To prevent dental injuries the wearing of mouth guards should be encouraged, especially in ice hockey, karate, and basketball.
Key messages
* Many sports injuries result from true accidents but others are preventable
* Injury rates are low in child athletes and highest in young adults
* Every sport has a specific injury profile
* Preventive measures should be specific to the sport concerned and include those aimed at decreasing the number of violent contacts between athletes

Study on Mechanism of Injury Generation and Reduction Therapy
Study on Mechanism of Injury Generation and Reduction Therapy based on Judo forms caled as Kata

The techniques of Hiza-gatame (knee lock) and Hara-gatame (stomach lock) called as Kime-no-Kata aim at a positioning of elbow joints to cause a dislocation. Here, the underlying mechanism for the dislocation theory and reduction theory were investigated from the aspects of Kansetsu-waza (joint techniques).
We examined the mechanisms focusing on the motion of body and the positioning of joints as well as power direction and its timing in relation to Judo-Seifuku therapy and verify the mechanism through Judo techniques in practice. Kime-no-Kata in Judo mainly consists of Atemi-waza (striking techniques) and Kansetsu-waza (joint techniques), and also includes Nage-waza (throwing techniques) and Katame-waza (grappling techniques). Their offensive and defensive techniques are essential for waza. These waza are able to verify the individual motion by actually reproducing the respective components. The techniques of Suriage (knee lock) and Tukkomi (stomach lock) aim to let the opponent loose balance utilizing the offensive force while keeping one’s own balance, resulting that direct and indirect forces are loaded on the opponent’s elbow joints. The force produced by Kansetsu-waza is able to easily induce a dislocation in an instance via the action of moment applying the principle of leverage. When compared with the
conventional reduction procedures in clinical practice and Roser’s procedures that retrospectively follow
the generation process of dislocation, these procedures for Seifuku therapy are basically coincident except for a loading of excessive extension on the elbow joint. Kansetsu-waza, a decisive technique form called as Kime-no-Kata aims to take a posture of dislocation by effectively loading an external force. The dislocation generation theory (injury generation mechanism) and the theory of Judo reduction therapy retrospectively following the generation process of dislocation from the aspect of kinetics were reviewed to clarify the respective characteristics. Thus, Judo-Seifuku theory was introduced through conversely tracing the individual motions of Kansetsu-waza.
