[2] In Chinese Language, "Sanda" originally referred to independent and separate training and combat techniques in contrast to "Taolu" (pre-arranged forms or routines).
Sanda is a fighting system which was originally developed by the Chinese military based upon the study and practices of traditional Chinese martial arts and modern combat fighting techniques; it combines boxing and full-contact kickboxing, which includes close range and rapid successive punches and kicks, with wrestling, takedowns, throws, sweeps, kick catches, and in some competitions, even elbow and knee strikes.
[5] Sanda's competitive history is rooted in barehanded elevated arena or Lei Tai fights in which no rules were observed.
[6] However, Sanda as a competitive event developed in the military as these bouts were commonly held between the soldiers to test and practice barehanded martial skills, ability and techniques.
This general Wushu Sanda curriculum varies in its different forms, as the Chinese government developed a version for civilians for self-defense and as a sport.
Examples of such restrictions included no blows delivered to the back of the head, throat, spine or groin and the discontinuation of the combat when any of the fighters fall to the ground.
However many schools, whether traditional or modern, practice it as an all-round martial arts system with no restrictions, only adapting their training in relation to competition rules prior to the event.
Sanda represents the modern development of Lei Tai contests, but with rules in place to reduce the chance of serious injury.
For safety reasons, some techniques from the self-defense form such as elbow strikes, chokes, and joint locks, are not allowed during tournaments.
