For any sport, there must be a level of what the IOC (International Olympic Committee) calls "universality"; in other words, the sport must be practiced under an international governing body in multiple countries in most continents. Essentially, the sport: Must have an international governing body. (For Judo, for instance, this is International Judo ...

First, Krav Maga doesn't refer to itself as a martial arts. It's more appropriately called "Self defense tactics system." This might seem like marketing fluff, but the idea is that there is no art to it, and it want's to separate itself from traditional martial arts. Second, there is no sports (also known as competitive) aspect to Krav Maga. Krav Maga ...

That's barely a modification of kesagatame. There's no gi, so he uses a slightly different grip. It totally counts. Just about all techniques, including pins, are modified in actual application. This is so true that the examples of throws that don't look obviously modified are shared as highlights and widely touted as beautiful paragons of the art. But a ...

Yes, omoplatas are considered a variant of ashi-gatame or hiza-gatame.1 3 The IJF Referee Commission has confirmed their legality on multiple occasions,1 2 both as a submission, and as a method of turning uke over from the turtle position: Lascau: Osaekomi. Demonstrator: *uke taps, tori points at armlock* Lascau: Ippon. Ippon. ...

Yes, the above technique would be a pin in competition judo. A pin in competition judo does not need to be a standard pin; it needs to meet the definition of a pin under the referee rules. This is good especially because judo people can get very nitpicky about what exactly constitutes a particular pin [more on that later]. If your opponent taps at any time ...

No they are not. The mouth guards are designed to protect against different kinds of impact most common to sports. You have the top only mouth guard which is meant to be something between your teeth for chomping impact. You have a separate top and bottom mouth guard which has a full set covering each teeth to help prevent outside impact into the teeth ...

Unconventional osaekomi-waza Most legally scoring pins come under one of the 10 osaekomi-waza classifications. However, I have seen a couple of unconventional pins which as far as I am aware do not come under any of these labels: "Inverted kesa-gatame" This is a technique favoured by Matsumoto Kaori and Funakubo Haruka, used to success a number of times: ...

TL; DR: It has to do with the fact that they have separate international governing bodies (see breakdown below). The Olympics have a tiered classification system, that can be a bit confusing if you look at each different thing as a "sport", like you would for general consideration. These tiers are: Sport - Top tier, and there are limitations on the number ...

As this is an extremely broad question, it befits an extremely broad answer. Any technique can be applied with varying degrees of success, whether armed or armored. Much of the kuden of the Bujinkan for instance is related to the sameness of arms and armor, and how techniques do not necessarily change with respect to equipment, and ultimately the goal of ...

Honestly, I think that Giulia Enders is using an artistic metaphor to conjure an idea of someone squatting in a relaxed but engaged position in much the same way that you might describe someone attentively awaiting a piece of post as "standing still at the door like a dog pointing" or bracing for a date rejection as "standing lightly on the balls of his feet,...

What you're looking for is martial arts demographics. And you want world-wide demographics. Both of which seem kind of hard to come by. The demographics you're looking for might be along the lines of: how many people are there doing martial arts, what percentage of the population is currently practicing one or has ever practiced one, average time spent per ...

What is an "elbow-lock"? While a common misconception, armlocks which cause pain to the shoulder are not inherently illegal in Judo. The phrasing "kansetsu-waza applied to the elbow joint" is used by the Kodokan to describe joint-locks which achieve their effect by: straightening or bending the elbow joint ("locking" it in place), and stretching, bending, ...

Grabbing neck to throw This is illegal. Judo kata has many techniques that are forbidden in sport judo because it is only safe to practice them in controlled situations. As a referee I would call hansoku-make for IJF SOR: Article 18.5 (hansoku-make) - Prohibited Acts and Penalties To make any action this may endanger or injure the opponent ...

I do not believe so. I know of no such data being available world wide, nor would I trust any such. Mostly because even something as "number of people insured" is not precise enough. Also, some schools/styles would heavily object being lumped together because ego. There is some hope… You could look per style/school and country by looking and trawling ...

At a guess, any of the Escrima/Kali guys that like the dog brothers. http://dogbrothers.com/ Their sparring is geared for a semi no rules with weapons ( often wearing protective gear similar to armour ) see http://www.youtube.com/watch?v=CELN-DQI5qc

Krav Maga is a relatively new martial art which was developed by Israeli military for military applications, as such it does not have a competitive/sports aspect as with Taekwondo or Seido.

I do not know exactly what "crucifix" means to you, but will try to explain how I have seen this term used and how your examples relate. Judo rule change My understanding of the rule change you have illustrated is: The left position was a pin before, and is a pin now (ushiro kesa gatame). The right position was not a pin before, but is a pin now (ura ...

I have seen no official documentation for this decision, so I can only relay what I have heard from international referees on this subject. Olympics The word in US referee clinics at this time was that judo was in danger of being removed from the Olympics because it was too easily confused with existing wrestling events. Remaining in the Olympics was seen ...

Currently there's no diagnostic assay for CTE. There's no treatment, nor is there any cure, either. According to Alzheimer's Association, the symptoms of CTE include: Memory loss. Confusion. Personality changes (including depression and suicidal thoughts). Erratic behavior (including aggression). Problems paying attention and organizing thoughts. ...

The IBJJF specifically bans1 two judo-throws where uke lands on their head/neck. Despite the IJF prohibiting throws which "may endanger or injure the opponent especially the opponent’s neck or spinal vertebrae", there are a number of throws where it is not uncommon5 in competition for uke to hit the mat first with their head, or impact with it after falling, ...

I was taught a compression armlock by a US national referee. I am not formally familiar with the term bicep slicer, but your description of the armlock matches exactly what I learned. It's a joint lock on the elbow that can be performed in a controlled manner, so there is nothing to make it illegal. It's legal. I don't recall whether I have seen this ...

Legality of te-gatame As one might infer from their presence in the video and current syllabus, the position of the Kodokan is that these bent-arm hammerlock versions of te-gatame are legal.2 3 4 The incongruence between te-gatame appearing on the IJF's list of legal techniques and the (occasional) penalisation of it in actual competition seems to stem ...

One major reason for the change (in addition to making refereeing easier) was to make judo more appealing to TV audiences, and in this the IJF explicitly disavows any responsibility to adhere to Japanese aesthetic or traditional values (and hence no pressure to consider e.g. indigo): As the birthplace of judo is Japan, the techniques and spirit of judo ...

Daki Age (High Lift, Slam) In judo, to escape from your opponent's guard position, you can stand up and pick them up off the mat. Once you have them off the mat, a referee will call matte and reset the match from standing. In a self-defense situation, the technique you would actually apply is daki age where you slam the opponent into the ground. This is ...

Found this explanation on a fencing website: In foil and saber there is a rule called right of way, or priority, which claims only one person may develop an attack at a time. If both fencers are touched it is up to the referee to decide which fencer will be awarded the touch and why. Difficulty arises when the priority relationship between the ...

The IJF criteria for osaekomi-waza are thus (emphasis mine): The referee shall announce osaekomi for an applied technique when the contestant being held is controlled from every direction (from the side, rear or on top) by his opponent and must have his full back or complete upper back (scapular region) in contact with the tatami. The contestant ...

Legal My personal understanding (sorry, no official guidance) is this use of the skirt portion of the jacket is legal. This is basically the same use of the opponent's gi as in kata juji jime. The rules are imprecisely written, which is very annoying. "Using only the fingers" would also seem to preclude ryote jime, but ryote jime is legal. Using a belt ...

I am only a low-level referee, but here is my best interpretation of the rules for this choke. I would call this version legal. Although uke's left arm is separated from uke's head, tori has control of uke's left shoulder and arm, either with an overhook or underhook grip. I would call this version illegal. This version actively isolates pressure only on ...

This probably refers to the horse stance: It is used in a lot of martial arts…
