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.

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

  • 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.

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.

Announcement

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.

Announcement

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.

Announcement

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.

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
