Regulation time for all men's matches will be five minutes, and regulation time for all women's matches will be four minutes. There are not multiple rounds during regulation time, but if there is no winner at the end of regulation time, judokas will compete in a sudden-death "golden point" overtime.
When watching a judo match, there will typically be a scoreboard that reflects the various scores that the competitors have earned during the match. The scoring is actually displayed as three separate columns, with a tally shown for each of the different types of scores. However, to better understand the scoring, it may be easiest to look at the scoreboard as if it were showing cumulative point totals. Below are the "point equivalents" that would correspond with each type of score.
1. Hansoku-make: Grave infringement. Calls for immediate disqualification of the offending judoka. Can be assessed for fouls such as intentionally trying to injure the opponent, unsportsmanlike conduct or for repeated violations of the rules. The negative equivalent of an ippon.
If the match goes the distance, the winner is decided on the basis of which judoka has accumulated the highest quality score. Whichever judoka has more waza-aris will win. If the number of waza-aris is the same, then whichever judoka has more yukos will win. (In judo, it is always the highest quality score that wins, so one waza-ari will beat any number of yukos.) If the point totals are the same, the outcome is decided in favor of whichever judoka has accumulated fewer shidos (penalties).
A competitor can give up by "tapping out." During a tapout, the surrendering judoka taps their arm, mat, self, or opponent repeatedly to ask him to release the technique. The surrendering judoka can also say "maitta" (I give up). Tapouts most commonly occur when a judoka is being choked and in danger of passing out, or when a judoka is in an armbar and in danger of having their elbow dislocated.
Electronic scoreboard: It can display the score, game number, time and serving right of HOME and GUEST.
5 scoring modes are available: basketball, tennis, volleyball, boxing, judo.
Power supply: battery powered (not included), long standby time, standard charging interface, two power supply methods. (low battery reminder function)
LED display: super bright LED display, clearly visible outdoors, long service life.
Portable: Thin and light, easy to carry, the score board can be hung on the wall or placed on a tripod (not included).
Ideal for sporting activities and gymnasiums (competitions, training, fitness sessions) where the sequences of action-pause are of a fixed duration.This timer is also useful for managing times for speakers.
To assess the specific level of fitness in judo, Sterkowicz (1995) created a Special Judo Fitness Test (SJFT). The test was designed to evaluate the specific abilities of judo athletes. SJFT partially respects the time structure of a real judo contest and uses the throwing technique over the shoulder (Ippon-Seoi-Nage)
Agostinho et al. (2018) compare the performances of male and female cadet and junior judo athletes and to develop classificatory ta- bles to these judo-specific tests for international-level from these ages. Data collected during training camps of male and female cadet and junior judo teams from three nations (Brazil, Serbia, and Spain) were analyzed, and authors created a detailed sex and age specific classification for judo-specific fitness. The use of these tests and classifications can be relevant for goal setting in terms of physical development either aiming at peaking for a specific competition or during different phases of the rehabilitation process. The responses to different types of periodization can also be monitored through the application of these tests.
Štefanovský et al. (2021) analyzed the available literature, and they found differences and considerable variability in the Special Judo Fitness Test (SJFT) reliability methods. For this reason, they determined the reliability and measurement error of all parameters by SJFT. According to the results of this study, by testing the special level of judo fitness, as well as its changes, authors recommend using the HR and SJFT index as good reliable parameter.
Kons et al. (2021) studied the validity of an adapted Special Judo Fitness Test (SJFT) for judo athletes with visual impairment. In their research, twenty judo athletes with visual impairments performed both the adapted SJFT with tactile and sonorous stimuli (experimental conditions) and the typically administered SJFT (standard condition). they found that both SJFT adaptations showed excellent reliability and medium sensitivity on test-retest, but, only the SJFT with the sonorous stimulus seemed valid for assessing judo athletes with varying degrees of visual impairment, and only the sonorous stimulus SJFT discriminated elite from sub-elite athletes.
Karimi (2016) studied the validity of SJFT in male wrestlers, founding that this test is a valid and reliable field test to evaluate anaerobic fitness in judo may be usable to evaluate anaerobic fitness in wrestling.
Recently Eken et al. (2022) have concluded that SJFT performance showed diurnal variation and judo performances of the judokas can be affected more positively in the evening hours especially after RAMP protocols. However, Ouergui et al. (2022) found that SFJT performance were not time-of-day dependent.
In this chart we can see the heart rate during the SFJT and during the recovery. After counting the number of throws done by the judo athlete during the 15/30/30 seconds periods, and checking the heart rate when he finish the test and 1 minute later, we have all the data to calculate the index and obtain his score.
