Our observations, from our travels and son competing:
1) USKA - United States Karate Alliance - We like this org the best so far and Jacob is a member. Originally, it was the US Karate
Association started by Robert Trias and was the first karate association and was first org to host martial arts tournaments. Upon Trias passing away, it re-organized into the US Karate
Alliance.
It is open to all styles and does not require membership to compete.
Point competition. For adults, rules allow medium to heavy contact to the body, medium contact to head and light contact to face. Basically, head contact is supposed to be controlled...if you draw blood or knock out your opponent you are DQ'd. Also groin contact is allowed. All strikes are scored 1 point as opposed to different strikes landed having different values. Matches are 5 point matches. Free Sparring with judges calling break when they see a point.....Head Gear, gloves, and Foot gear required.
Hosts tournaments in Louisiana, Texas, Arizona, New Mexico, and California
2) PKC - Professional Karate Commission - Started by Glenn Keeney Looks to be modeled after the USKA with mostly the same rules and scoring.
Hosts Tournaments in Indiana, Illinois, Ohio, Kentucky, and Pennsylvania. Open to all styles and non-members.
3) USKK - United States Karate-Do Kai - Started by Phillip Koeppel, Also, modeled after USKA with the same rules and scoring.
Hosts Tournaments in Indiana, Illinois, Michigan, and California. Also Co-Sanctions many tournaments with USKA.
4) WKF - World Karate Federation - Affiliated with the Olympics.
Styles recognized are
Gōjū-ryū,
Shitō-ryū,
Shotokan and
Wadō-ryū.
Scoring is much different than the first 3 orgs- Punches are 1 point, kicks to body are 2 points, kicks to head are 3 points. Punches and kicks have to be thrown and brought back a certain way to score and competitors have to disengage when they have scored for the judges to score them. Amount of contact allowed is about the same as the first 3 orgs.
More restrictions in what kind of sparring gear is allowed and type of Gi worn than the first 3. Open to non-members but they require techniques used to be done in the styles recognized above.
5) NBL - National Blackbelt League - Sport Karate Org. Hosts tournaments nationwide. Rules seem to vary depending on area. Son only competed in a few of these and we didn't care for them as much. Lot of XMA influence.
From what we have seen...USKA, USKK, PKC, and WKF tends to be much more traditional in style. NBL tends to be more XMA.
