Receiving A Technique
Ukemi (受身, Receiving With Body) is a vital aspect of aikido, a person will spend at least half their time taking ukemi. It is the art of surviving and receiving technique.
On its most basic level it is positioning and moving the body this includes rolling and falling exercises. The practices allow a person to become confident about receiving techniques allowing them to be projected with vigour and speed without fear of harm. Receiving ukemi requires a person to be able to follow a technique and adjust to any change in speed and direction.
The Uke may rotate or fall in any direction as if a sphere, which means they must train to be able to roll or fall in any direction. The only safe way to take ukemi is to remain relaxed and not resist the technique.
Beyond this as ukemi is matching the partners movement it then becomes possible to counteract or reverse the technique this is called kaeshi waza (返し技).
Techniques In Aikido
Aikido, inevitably is practiced by a series of techniques called waza 技which can be classified into types. Aikido can be divided into two types of practice Katame waza which includes Kansetsu waza and Nage waza which includes Otoshi and Kokyu nage.
Furthermore Techniques can be performed to the front (表, omote) often beginning with an irimi movement this is common for a pulling force. Or they can be performed to the back (裏, ura) often starting with a tenkan motion, common for a pushing force. Aikido also takes in account relative heights both partners standing (立ち技,Tachi Waza), both partners sitting (座り技, Suwari Waza), sitting against a standing opponent (半身 半立ち 技,Hanmi Handachi Waza).
These techniques help demonstrate the practitioners control and finesse. Precision is required in the execution of these techniques. They control and Manipulate the body using the joints and rotation motions. Katame means to solidify or harden in context mean to pin. Kansetsu means joint and refers to joint manipulation.
These techniques result in uke (refered to as nage 投げ here) being projected away giving stategic space or allowing an escape. These techniques are also good for improving ukemi and help to hone timing and awareness. These are commonly executed in multiple attacks during exams.
These techniques result in uke (refered to as nage 投げ here) being dropped down rather than projected, this is useful in restricted space also. These techniques are also good for improving ukemi and help to hone timing and awareness.
Hip throws are techniques are projections where tori sweeps below uke and rolling them over the hips. These techniques have a high breakfall (飛ぶ, tobu Ukemi) and are quite advanced.
These techniques are projections where tori does not actually grab their opponent. Instead they control using kokyu rokyu (呼吸力 , breathing power) and musubi (結び, tie) leading their partner into a projection. It helps to hone contact and breathing bringing focus and fluidity to the technique.
