Before the Tournament:weigh-insAthletes will weigh-in the day before the competition. Random weight checks will be organized before the first fights, the morning of the competition. The weight of the athlete cannot be more than 5%higher (without judogi) than the official maximum weight limit of the category. This is to ensure proper weight-cutting techniques are being done by athletes.

Match Duration
Men's matches last 5 minutes, female matches last 4 minutes. There are no designated breaks during a match. However, the referee stops the clock during breaks in action, such as a contestant stepping out of bounds, to make sure that the judokas compete for the entire time.
Objective
In Judo, the objective is to score an ippon (one full point). Once such a score is obtained the competition ends. An ippon can be scored many ways. Here are some examples:
If the point totals are the same at the end of regulation, the winner is determined by "golden score," which is sudden death overtime. The clocks are set for another five minutes (for males) or four minutes (for females) and the first judoka to get a score wins the match. An athlete can also record a win if the opponent receives a penalty.
- A throwing technique when one opponent is thrown on their back with considerable force or speed
- Holding the person in a pin for 25 seconds
- One person gives up by tapping (due to a choke, arm lock, or injury)
- One contestant is disqualified for violating the rules (hansoku-make)
- Earning two waza-ari (half points)
- One opponent gets 4 shidos (penalties)

Scoring in JudoPositive scoring
Ippon Equal to one full point, and a win, an ippon is a full throw in which a contestant throws the opponent to the mat with considerable force and speed so that the opponent lands on his or her back. Ippon is also awarded when a contestant immobilizes his or her opponent with a hold for 25 seconds, or when an opponent gives up or passes out. If an opponent does pass out, only a doctor or trainer is allowed to administer "katsu," or resuscitation. An ippon immediately ends a match. When signaling an ippon, the referee's hand is straight up. Waza-ari Equal to a half-point, a waza-ari is a throw that shows power and superiority but isn't clear enough to be an ippon, either because the opponent didn't land primarily on his or her back or because the throw lacked speed or force. Waza-ari is also awarded for immobilizing an opponent for at least 20 seconds (but less than 25). Two waza-aris end a match. For a waza-ari, the referee's hand signal is the arm out at shoulder level. Yuko Usually called an "almost waza-ari," a yuko is worth 1/4 of a point. A common yuko is throwing an opponent on his or her side. Yuko is given for a throw that is lacking in two of the three elements of an ippon: putting the opponent on his or her back; speed of throw; force of throw. Yuko is also given for immobilizing an opponent with a hold for 15 seconds or more, but less than 20 seconds. No number of yukos can equal a waza-ari in the final tallying of the fight's outcome. To signal a yuko, the referee's arm is raised 45 degrees out from the side. Negative scoring Hansoku-make Hansoku-make is given for a serious violation, calling for the immediate disqualification of the offending athlete. This can be given for violations such as intentionally trying to injure the opponent, or for repeated violations of the rules. This penalty is the negative equivalent of an ippon. Shido Shido is given for a slight violation, or for any rules violation that does not require an immediate disqualification. A Shido can be called on a judoka not attacking enough, intentionally stepping out of bounds, playing too defensively, or putting a hand directly on the opponent's face. If a player gets 4 Shidos, they are disqualified and lose the match.**Source |
