During the Middle Ages, Japanese warriors fought to the death, melee and without weapons, following different techniques and methods (Martial Arts). In Japan, all of them were encompassed in what is known as Jiu Jitsu, under their different schools with judo uniform.
From two of them, Jigoro Kano developed in 1882 a new one called Judo. In it, as in others, maximum efficiency was cultivated during combat, but its objective was not the death of the rival. Kano created a new school, Kodokan. In it he sought a method of physical, intellectual and moral education through the practice of Martial Arts. A discipline that really allowed the application of its different techniques, since the opponents were not worried about killing or dying, just to execute them correctly.
Over more than 100 years, Judo developed and perfected to become one of the 4 most practiced fighting styles in the world. It has been part of the Olympic Games since 1964 (with the exception of 1968) and since 1992 in the women's modality.
From it, other current forms of martial sports such as American Jiu Jitsu, Russian Sambo, Krav Magá, Brazilian Jiu Jitsu or Nihon Tai Jitsu have emerged.
Sports Judo or gi for judo also sometimes called Olympic Judo, is regulated by the International Judo Federation (IJF). Although each National and Continental Federation can have its own regulations, IJF is the one who organizes and regulates the competitions worldwide. Olympic Games, World Championships, Continental Championships, Youth Olympic Games and World Tour, among others, are the events that fall under the regulations of this organization. Regulation on which we rely on these two articles.
It should be noted that, although the Absolute and Junior World Cups have an annual periodicity, these are not celebrated in the Olympic year.
Weight Control in Judo
And how are weights controlled so that each judoka is in its category? Well it is done in three phases:
- Unofficial Control
- Official Control
- Official Random Control
The first two are held on the eve of the competition of each weight. Unofficial Control is done at 19:30. In it there may be a variation on the weight limit of the category.
The Official Control takes place at 20:00 and is much more rigorous:
- If judoka does not show up, it is disqualified.
- If it is above or below the category's weight range, it is disqualified.
Finally, Random Control takes place on the same day of the competition. It is made to 4 athletes of each category, chosen at random.
In this case a slight variation of weight of 5% over the maximum is allowed. That is, for the category -52 kg, up to 54.6 kg are allowed. If you exceed that limit, you are disqualified. The same happens if it is not presented to the control. In the event that any disqualification occurs at this stage, his opponents move on to the next round with a victory for non-attendance.
