The Japanese systems of hakuda, kenpo, and shubaku display some degree of Chinese influence in their emphasis on atemi-waza. In comparison, systems that derive more directly from Japanese sources show less preference for such techniques. However, a few jujutsu schools likely have some Chinese influence in their development. Jujutsu ryu vary widely in their techniques, and many do include significant emphasis on striking techniques, though in some styles only as set-ups for their grappling techniques.
In jujutsu, practitioners train in the use of many potentially fatal moves. However, because students mostly train in a non-competitive environment, risk is minimized. Students are taught break falling skills to allow them to safely practice otherwise dangerous throws.
In jujutsu, there are five main sectors ("arts") of training. The first, the Art of Blocking, is used to defend against attacks. The second, the Art of the Fulcrum Throw, is employed in modern judo. The third, the Art of the Non-fulcrum Throw is employed through throws that involve little or no contact with the opponent. The fourth, the Art of Escaping (Hakko-Dori), is very crucial in many styles of Jujutsu. The fifth is the Art of Striking (Atemi-Waza).
The word Jujutsu can be broken down into two parts. "Ju" is a concept. The idea behind this meaning of Ju is "to be gentle", "to give way", "to yield", "to blend", "to move out of harm's way". "Jutsu" is the principle or "the action" part of Ju-Jutsu. In Japanese this word means science or art.
Japanese kickboxing originates in the 1960s, with competitions held since the 1960s. American kickboxing originates in the 1970s. Japanese kickboxing developed into K-1 in 1993.
Historically, kickboxing can be considered a hybrid martial art formed from the combination of elements of various traditional styles. This approach became increasingly popular since the 1970s, and since the 1990s, kickboxing has contributed to the emergence of mixed martial arts via further hybridization with ground fighting techniques from jujutsu and professional wrestling.
There is no single international governing body. International governing bodies include World Association of Kickboxing Organizations, World Kickboxing Association, International Sport Karate Association, International Kickboxing Federation, World Kickboxing Federation, World Kickboxing Network, among others. Consequently there is no single kickboxing world championship, and champion titles are issued by individual promotions, such as K-1, It's Showtime, Lumpinee Boxing Stadium, among others
San Shou/San Da;
San Shou / San Da literally means scattering hands/arms or scattering / unbound strikes, and refers to free combat. Lei Tai is the old name referring to the platform it is fought on. Originally a win could be achieved by knocking the opponent off the stage, nowadays this has changed to a 3 point score, a platform without ropes or edges forces the fighter to 'stand his ground' or else learn to move extremely quickly and sharply, perilous edges exist in real fighting - walls, drops, terrain. San Shou tries to simulate these factors. Scores can be obtained through striking or cleanly felling an opponent or landing on top of him after a throw, or by using sacrifice techniques, however the 3 second wrestling rule still applies and prolonged stand up or ground entanglements are broken up. Originally Lei Tai fighting could include weapons, think of the kung fu movie "Fearless", so the reasons behind discouraging protracted engagements with a single, possibly armed, individual become evident. Today in general San Shou refers to amateur fighting - head gear, no elbows or knees, and San Da - pro-rules no head gear, and elbows/ knees allowed.
San Shous 4 characteristics compose of:
Die Pu: Striking (kicks, punches, elbows, Knees etc.)
Shuai Jaoi: Throwing / Wrestling
Chin Na: (Seize / Hold) Joint Locks, grips and twists etc.
Dim Mak: 'Spotting' Point / Pressure Strikes, Regardless of popular belief this is not about crouching tiger/ hidden ropes, nor does it simply involve striking. It more correctly refers to targeting and the application of pressure to areas that enhance the effect of techniques. These targets should not be 'out of the way' but natural and efficient. This pressure need not be applied by the fingers nor even the arms, get the idea?
Today the main bodies responsible for san shou competition are the IWUF, IKF and IMAF.
