Karate
Karate is divided into style organizations. These organizations sometimes cooperate in non-style specific sport karate organizations or federations. Examples of sport organizations include AAKF/ITKF, AOK, TKL, AKA, WKF, NWUKO, WUKF and WKC. Organizations hold competitions (tournaments) from local to international level. Tournaments are designed to match members of opposing schools or styles against one another in kata, sparring and weapons demonstration. They are often separated by age, rank and sex with potentially different rules or standards based on these factors. The tournament may be exclusively for members of a particular style (closed) or one in which any martial artist from any style may participate within the rules of the tournament (open).
