| hapkido is korean, but they have the same origin in Japan, and it incorporates much more hard techniques into the MA. one of the clips they showed on that computer thing, if i remember correctly, was a basic tripping technique using the manipulation of the wrist. in aikido it is very fluid and graceful... if both parties execute it properly, the energy is just transfer from one person to the other with out pain. thus in a street situation, it is very affective because they practice with a lot of energy and the attacker doesn't know how to disapate it and breaks bones.... in hapkido, the movements are fluid, but less so, and the end of the move there is a bit of an explosion of energy used... you get them into a vulnerable possition using energy flow and then bamb, break them.
that and hapkido uses kicks punches and to a lesser extent knees and elbows, plus weapons at some levels. aikido doesn't, they concentrate on manipulation of energy, they might use weapons as well, i am not sure.
if i misrepresented aikido someone correct me!! |
