The objective of this study is to examine the sensitivity to and changes in heart rate variability (HRV) in stressful situations before judo competitions and to observe the differences among judo athletes according to their competitive standards in both official and unofficial competitions. 24 (10 male and 14 female) national- and international-standard athletes were evaluated. Each participant answered the Revised Competitive State Anxiety Inventory (CSAI-2R) and their HRV was recorded both during an official and unofficial competition. The MANOVA showed significant main effects of the athlete's standard and the type of competition in CSAI-2R, in HRV time domain, in HRV frequency domain and in HRV nonlinear analysis (p
It's not exactly light summer reading, but but if you want to learn Nage no Kata or Katame no Kata, this is your book. Three stars (out of four)

The Upshot:
Everything you ever wanted to know about the Randori no Kata (Nage no Kata and Katame no Kata). It gives you the details for Uke and Tori in an easy-to-follow manner. And when I say that it gives you the details, it even covers how to sit up after you are thrown. 450 pages, over 1,000 illustrations... lots of detail. Not one that you will want to read cover-to-cover (God help you), but if you want to investigate a particular technique, you'll almost assuredly find what you need in here.
What's In It, and How It's Organized:
There are not many judo kata books out there, making this one the bible of judo's randori-no-kata. I can not remember the year of publication (1982?), but inadvertently, this book single handedly started the "cookie cutter kata" phase several years after publication.
Nnk prior to that time was more alive and personalized, with each individual performing it as it worked for him/her. I am a firm believer that such freedom to make each technique one's own can improve your personal judo.
The BJA syllabus lists a number of non-kodokan names for throws. Some of them are clearly names for common competition variants,1 but some I have never heard of e.g. ashi-dori, which looks to me like kuchiki-taoshi.
All judo techniques have their variations. For example, the 'circle throw'(tomoe-nage) may be performed either in the traditional way or to theside. This raises the issue of whether the two methods should be namedas separate techniques. One school of thought is that they are simplyvariations on the same technique, while the other presents the view that,although the basic principle of the two variations may be similar, thedifferent grip or direction of movement justifies them being regarded asdistinct techniques (in this case, the 'circle throw to the side' should becalled yoko-tomoe-nage).
...
This presentation supports the case for specifying and naming contestwaza that have previously only been recognised as variations of theestablished techniques. The rationale for this is that it will assist coachesin the teaching and demonstration of contest techniques. To give anexample; any leg-grabbing action (one of the highest scoring actions inmajor tournaments) will be termed simply 'ashi-dori', but the specificvariation used may require different direction of force and/or handplacement.
...
The names used to describe the techniques in this research poster arenot intended to be definitive, merely indicative. The paper proposes thatappropriate bodies such as the International judo Federation or theKodokan should look towards expanding the number of officiallyrecognised techniques and addressing the issue of the correct names restswith them.

The apparent renaming of Kuchiki-taoshi to kata-ashi-dori, while retaining kibisu-gaeshi, was done presumably to use only explicitly descriptive names (and not metaphorical ones). I presume yama-arashi and tsubame-gaeshi would similarly be relabelled "kata-eri-harai-goshi" and "de-ashi-gaeshi" if they were included. Tomoe-nage is ubiquitous enough to have escaped such renaming.
The competition starts with a preliminary round, then proceeds to the Round of 16, quarterfinals, semifinals and final. For the most part, the tournament is single elimination, with one key exception: Judokas who lose in the quarterfinals and semifinals will have the opportunity to compete for bronze medals (described in the next section).
The losers of the four quarterfinal matches are pulled into repechage matches. The two losers from the top half of the bracket will face each other, as will the two losers from the bottom half of the bracket. The winners of the two repechage matches will advance to separate bronze-medal matches.
Each team will be comprised of six judokas (three men, three women) competing across the six different weight classes listed below. Judokas are allowed to compete in higher weight categories than they normally do. (For example, a 52kg woman can compete in the 57kg class.)
In each weight class, the top eight athletes (based on the world rankings) will be seeded in order to avoid having top competitors face each other early in the tournament. All other judokas will have their spots on the bracket determined by a random draw.
Athletes will attend the official weigh-in on the day before their weight class is scheduled to compete. They will have one chance to officially weigh in, and they will not be allowed to compete if they weigh above or below the limits (in kilograms) for their division. There will be an unofficial weigh-in period beforehand, during which time athletes can use the official scales to check their weight.
While an Egyptian judoka's refusal to shake hands with his Israeli opponent at the Rio Olympics reverberated worldwide, in Israel the focus is on national Olympic medals - something far more novel than Middle East tensions.
After defeating Egyptian Islam El Shehaby in the contentious first round match in Rio, Israel's Or Sasson went on to win a bronze medal in the heavyweight category. His triumph, and another bronze medal for Yarden Gerbi in the women's 63-kilogram judo division, has set off a national celebration in which the nation's leaders have hailed the pair as heroes.
The watershed moment came at the 1992 Barcelona Games when Israel earned its first two Olympic medals, both in judo - a silver for Yael Arad in women's half middleweight and a bronze for Oren Smadja in men's lightweight. Those performances finally gave Israel something to cheer about at the Olympics 20 years after Palestinians murdered 11 Israeli Olympic team members at the 1972 Munich Games.
