Its techniques originated in the throws and joint locks of jujitsu, where an attacker's strength and momentum are used against himself, and from sword techniques (kenjutsu). Emphasis is placed on absorbing and redirecting an attack rather than blocking or parrying. Aikido methods are often used in women's self defence classes since they do not rely on strength. Unlike many other martial arts, the aim of Aikido is to subdue rather than to maim or kill an opponent.
Aikido is a way of defence. Although it may seem contradictory with the concept of a martial art, the underlying philosophy behind Aikido is one of peace and harmony. ('Aikido' may be translated as 'The Way of Harmony with the universe or spirit)'. It teaches the importance of achieving mental calm and control of one's own body in order to master an opponent's attack without causing them unnecessary harm.
Many different styles of Aikido have evolved from O Sensei's original teachings. Only one, Tomiki Aikido, involves any form of competition. Aikido training is of a co-operative nature rather than antagonistic, with performer (nage) and the reciever (uke) working in partnership.
