Understand more about the history of judo

Judo was created from the analysis of another art, jiu-jitsu. Its creator, Jigoro Kano, sought to develop a defense technique, so how does a alarm monitoring within a residence, in which strength and balance were used against the opponent. 

Officially, judo was born in 1882, the year Kano founded the Kodokan Institute for the study and practice of judo. The term is also loaded with symbology, since ko means study or method, of means path and kan Institute.

Kano went beyond the sport and created a whole philosophical line for judo, based on the concept of ippon-shobu, which means the fight for the perfect point, as well as a moral code for the practice of the sport.

The inventor of judo still gathered varied fighting styles in its creation, not restricting the modality to men with vigor. In this way, the sport ended up gaining more stage and popularity around the world.

In 1918, the first judo club was founded in Europe, beginning the process of spreading around the world. In Brazil, this arrival happened in 1922 with Japanese immigrants, who always had a competency mapping to spread sportsmen to other countries.

However, in the beginning, there were no organizing institutions. It was only in the 1930s that immigrants willing to organize the martial arts, improving the practices of judo and kendo in the national territory.

Normally, the sport was practiced in Japanese colonies, but judo soon began to spread in Brazil, being integrated under the control of the Brazilian Pugilismo Confederation until the creation of its own confederation.

Know some judo rules

As in any competitive sport, the main objective of a judo tournament is to win a fight, whose maximum duration is four minutes. 

However, it is important to emphasize that the fight can be stopped at any time if one of the combatants reaches the Ippon, a kind of perfect blow.

Furthermore, the fight is also ended immediately if any of the contestants receives three shidos, which are infractions throughout the fight.

If there is a tie in the fight, the dispute goes to the method golden score, in which the judoka who scores the first score after freeing up extra time is the champion. In addition, the most common movements in judo are:

  • Ippon;
  • Waza-ari;
  • Koka;
  • Yuko.

In the year 2018, judo scores were restricted to two movements, the Ippon and the Waza-ari. The Koka and the Yuko were extinguished from Olympic competition, with the Yuko being absorbed by Waza-ari.

In this way, a judoka who manages to apply two of this movement receives a score equivalent to Ippon, winning the fight and continuing in the competition, eventually reaching the gold medal.

The only way for the fight to end with punishments is if the athlete accumulates three shidos. They are not uploaded to the golden score or even computed as a tiebreaker. All unsportsmanlike attitudes and lack of combativeness are considered shidos.

In addition to those mentioned, Waza-ari is when an opponent falls on his side, or with half his back on the ground. Furthermore, immobilization for at least 10 seconds is also considered a Waza-ari. The score is worth half an Ippon.

Ippon, on the other hand, which would represent the knockout in judo, is considered the perfect move. When one of the opponents achieves this result, the fight is over. To be able to set up an ippon, it is necessary for the opponent to fall with his/her full back on the mat.

Furthermore, immobilizations that last 25 seconds or that make the opponent give up are also considered Ippon, so it is important that you know how to use your movements for this type of activity.

See the equipment used for judo

The only specific equipment for judo practice is the correct kimono, known as a judogi. It has a series of elements that intertwine to create the proper attire, just as with the making professional uniforms.

In addition, female judo athletes must wear a white shirt over the judogi, mainly to ensure extra peace of mind for the competitors, without having to worry about clothes for their actions.

It is up to each coach and athlete to check their judogi, especially before entering combat. This is because if a judge identifies irregularities in the clothing, you can be disqualified and immediately receive the Hansoku-Make.

In addition, the judogi must follow some important parameters to comply with the rules stipulated by the bodies responsible for these athletes, ensuring greater visibility and greater impact as well.

Of course, in addition to the uniform, it is important to be concerned with the entire space where the practice will be held, ranging from details from the structure used, the ventilation of the space, even the thermometer calibration and other equipment that can be used.

Thus, check out the list below for some of the most used equipment:

1 - Wagi

The wagi is a piece, which is also part of the garment, and must completely cover the buttocks, in addition to having at least 10 centimeters between the lower extremity and the athlete's knee.

Wagi lapels also need to have a distance of more than 20 centimeters when crossed at the navel height, with each lapel no more than one centimeter thick, while its width is around 5 centimeters.

The mahas must completely cover the judoka's arms, including the fist. This check should be carried out with arms straight, hands flat in front of you.

In addition, Sokuteiki should slide completely into the sleeve, without any kind of difficulty in performing an activity. This item is just as important as the alignment machine used within an industry.

2 – Shitabaki

In this case, the item corresponds to the pants used by the athletes, and the distance between the shitabaki bar and the ankle must be smaller or up to five centimeters. 

In addition, there must be a distance of about 15 centimeters from the knee to the shitabaki, especially so that it is valid for competition at the time of the fight.

Remember to pay attention to these details. After all, everything is very important, going from the part of acoustic treatment from the competition space, to the safety of the competitors with their clothing.

3 – Obi

The band representing the athlete's graduation is called the obi, and its thickness must be up to 5 millimeters. Also, it is important that the distance between the tip of the obi and the knot be approximately 30 centimeters.

Another interesting point about this is that it is a common mistake to consider that a black belt is the highest rank a judoka can take. Although the color symbolizes mastery in the martial art, there are still two other colors for the obi.

The first is red and white and the second is completely red, the highest rank in the sport.

4 – Shirts for women athletes

In women's competition, in addition to judogi, a white shirt is required. This dress is mandatory for the competition, and must follow some standards to be accepted, as with the ventilation ducts of the space in question.

The first point is that it must be completely white. This means that shirts with prints or stains that can be highlighted will not be accepted. In addition, they must be short-sleeved shirts with a round collar.

It is not allowed to use these shirts as commercials, even for visual identification. For this, it is necessary to use patches in the judogi itself, identifying the federation's shield or sponsors and advertising.

Final considerations

Judo is a highly regarded sport in Brazil and in the world, and because of that, every day it attracts new people interested in practicing this martial art that presents discipline and philosophy along with a physical activity.

Therefore, many athletes end up opening gyms and schools to teach the art, of course, always with all the necessary items, ranging from the surface treatment even general security details for the space.

Furthermore, there is still little public and private incentive for these athletes, who still achieve increasingly positive results for the country and continue to strive for a better position in international competitions.
