Judo vs. Sambo
Quick answer
Sambo emerged in the USSR in the 1920s and 1930s, and one of its creators, Vasily Oshchepkov, trained at the judo Kodokan. Judo allows chokes and locks only on the elbow, while sport sambo, according to FIAS, forbids chokes and allows leg locks and leg grabs. Judo has been Olympic since 1964, and sambo has had full IOC recognition since 2021 but is not on the Olympic programme.

History and relationship
Sambo emerged in the RSFSR and the USSR in the twenties and thirties for close combat in the Red Army and other services. One of its creators, Vasily Oshchepkov, trained at the Kodokan under Kano Jigoro. The other, Viktor Spiridonov, drew on jiu-jitsu he had studied on his own. Sambo has no single founder.
- 1882: Kano Jigoro founds the Kodokan in Tokyo.
- 1917: Oshchepkov becomes the first Russian to earn nidan at the Kodokan.
- 1923: Spiridonov co-founds the Moscow Dynamo and leads its self-defence section.
- 1937: Oshchepkov is arrested during the Great Purge and dies in prison in October.
- 16 November 1938: the All-Union Committee for Physical Culture and Sport recognises sambo as an official sport.
- 1964: judo appears at the Olympic Games for the first time, the USSR wins four bronze medals in it, and the medallists include the USSR sambo champions Oleg Stepanov and Ārons Bogoļubovs.
The name is an abbreviation of the Russian samozashchita bez oruzhiya, self-defence without weapons. Sources state that it became established in 1947 on the initiative of Anatoly Kharlampiev, Oshchepkov’s student, although Spiridonov had already used a similar name.
Technique
- Throws (nage-waza) and groundwork (katame-waza): holds, chokes, locks.
- Locks in competition only on the elbow.
- Grabbing a leg or gripping below the belt is penalised with shido (interpretation of the IJF 2023 and 2025 rules).
- An ippon for a clean throw onto the back ends the match, and a hold wins after 20 seconds.
- Strikes only in kata.
- Throws and groundwork in the kurtka, a hold for 20 seconds scores 4 points.
- Painful holds only against an opponent on the ground, forbidden in standing (FIAS 2023).
- Locks on the elbow and on the legs (knee, ankle), while heel twisting, leg knots, the knee lock against the joint and scissors on the knee and ankle are forbidden.
- Choking is forbidden in sport sambo.
- A throw onto the back scores 4 points, and a clean throw (perfect throw) means total victory.
The main technical difference lies in the finishing techniques. Judo allows chokes and locks only on the elbow, while sport sambo allows locks on the elbow and on the legs and forbids chokes. Judo also penalises grabbing a leg. Combat sambo adds strikes and chokes to this.
Training
| Judo | Sambo | |
|---|---|---|
| Main form of sparring | randori at various intensities | we have not found a source |
| Technique practice | uchi-komi and four types of falls (ukemi) | we have not found a source |
| Measured load | randori 4 × 5 minutes: heart rate 174–183 per minute | we have not found a measurement |
We have not been able to document how a sambo lesson is structured, as the FIAS rules describe only competition. For judo we have not found a typical ratio of technique, sparring and conditioning.
Progression and ranks
| Judo | Sambo | |
|---|---|---|
| Student grades | 6 kyu: white to brown belt | does not use coloured belts |
| Master grades | 10 dan, red-and-white belt from 6th dan | Master of Sport title for competition results |
| Who awards them | Kodokan and national federations | FIAS, FKE and other organisations |
| Age | shodan from age 15 (United Kingdom), in the USA usually from 16 | FIAS age categories starting with cadets aged 14–16 |
| Minimum times | we have not found them in the sources | not used, competition decides |
In judo, level is shown by belt colour and examination, in sambo by competition ranking. We have not found in the sources a system of classes, for example candidate master of sport, or FIAS belts.
Physical load and risks
- Olympics 2008–2016: 9.6 injuries per 1,000 minutes of competition (BJSM 2021).
- Pocecco et al. (2013): most often the knee, shoulder and fingers, about 70% of injuries when thrown by the opponent.
- Blach et al. (PeerJ 2022): 78% of injuries in standing.
- Lapaeva et al. (Translational Sports Medicine 2025): a questionnaire of 61 injured adults, 74% sambo and 26% judo.
- Knee 39.3%, shoulder 31.1%, elbow 26.2%, anterior cruciate ligament rupture 24.5%, 44% treated surgically.
- Rapid weight loss before a competition was associated with injury in competition (OR 5.59).
- We have not found the incidence of injuries in sambo.
Who it suits
| Judo (IJF) | Sambo (FIAS) | |
|---|---|---|
| Lowest competition age | IJF events from age 15 | cadets aged 14–16 |
| Adults | seniors from age 15 | adults from age 18, match 5 minutes |
| Older age | veterans up to over 70, no chokes from age 60 | masters from age 35, match 4 minutes, over 65 years 3 minutes |
| Women | Olympic medals since 1992 | separate competitions, women wear a white T-shirt under the kurtka |
Children
| Judo | Sambo | |
|---|---|---|
| Lowest competition age | national rules, for example Judo Victoria (Australia) from age 6, IJF from age 15 | FIAS 2023 cadets aged 14–16, the 2015 rules also 11–14 |
| Protection of children | Judo Victoria: under 15 no locks, chokes or headlocks, under 9 no sutemi-waza | choking forbidden for everyone, we have not found rules for children |
| Match length | 2–3 minutes depending on age (Judo Victoria) | youth and cadets 4 minutes |
| Combat sambo | — | only juniors and adults |
| Study | Polish study (1977–1980): injuries in 5.7% of youth, 22.5% of adults | we have not found a study of children |
Self-defence
- Randori against full resistance in standing and on the ground.
- Strikes and weapons forbidden even in free practice.
- Defence against attacks in the kata Kodokan goshinjutsu.
- Sport sambo: full resistance in throws and on the ground, without strikes and without chokes.
- Combat sambo adds strikes, chokes and protective equipment.
- According to the source, the self-defence form focuses on defence against weapons.
Both arts practise throws and control on the ground against a fully resisting opponent. Strikes are trained only in combat sambo. We have not found a source on the usability of sambo outside the competition rules.
Practical use
| Judo | Sambo | |
|---|---|---|
| Self-defence forms | kata Kodokan goshinjutsu and Joshi-goshinho | self-defence sambo, defence against weapons |
| Professional use | we have not been able to document it | created for the Red Army, Oshchepkov taught on army and militia courses |
| Older age | review of 23 studies (Sports 2023): less fear of falling in some | masters from age 35, we have not found a study |
| Fitness | 10 advanced judoka, randori: heart rate 174–183 per minute | Tron et al. (2013): tests of 94 combat sambo competitors, did not measure the benefit of training |
The studies describe small groups or advanced competitors. No general suitability of judo or sambo for a particular group of adults can be drawn from them.

Switching and combining
- Grips, throws, falls, holds and elbow locks carry over.
- Learn the leg locks and leg grabs that judo penalises.
- Unlearn chokes and get used to the kurtka and shoes.
- Throws, grips on the clothing and holds carry over.
- Unlearn grabbing the legs and leg locks.
- Add the chokes that sport sambo forbids.
On the left is the move from judo to sambo, on the right the opposite. The 1964 Olympic bronze medallists in judo Oleg Stepanov and Ārons Bogoļubovs were also USSR sambo champions. Oleg Taktarov holds the title Master of Sport in sambo and a 3rd dan in judo.
Forms and terminology
Judo has ten kata recognised by the Kodokan, for example Nage-no-kata with fifteen throws practised on both sides and Katame-no-kata with fifteen techniques on the ground. Sambo has no forms, and level is shown by competition.
Training culture
- Kodokan in Tokyo: an eight-storey building with five dojo, the main one has 420 tatami.
- Japanese terminology and belt colour showing the grade.
- Roots in the army and in the Moscow club Dynamo, where Spiridonov led the self-defence section.
- A memorial in Moscow’s Luzhniki from 2020 commemorates Spiridonov, Oshchepkov and Kharlampiev as founders.
- Russian terms, for example kurtka, and the title Master of Sport.
Common misconceptions
- Sambo was not a demonstration sport at the 1980 Olympics: sources describe this claim as a common historical error. Sambo is still not on the Olympic programme today.
- Anatoly Kharlampiev as the sole father of sambo is, according to the source, more a legend than a fact. Alongside him stand Vasily Oshchepkov, a judoka from the Kodokan, and Viktor Spiridonov.
Which to choose
Frequently asked questions
Did sambo originate from judo?
In part. Vasily Oshchepkov trained at the Kodokan, but Viktor Spiridonov drew on jiu-jitsu and wrestling, and according to the source the folk wrestling of the Caucasus and of Turkic peoples also influenced sambo.
What is the main difference in the rules?
Judo allows chokes and locks only on the elbow and penalises grabbing a leg. Sport sambo, according to FIAS, forbids chokes and allows leg locks and leg grabs.
Is sambo Olympic?
No. The IOC fully recognised FIAS in 2021, but sambo is not on the Olympic programme. Judo has been Olympic since 1964, except in 1968.
Do sambo practitioners have belts like judoka?
No. In sambo, level is shown by competition results and the title Master of Sport, while judo has 6 kyu and 10 dan.
