Gymnastics
Gymnastics may be divided into two main categories:
Auxiliary exercises:which have the aim to increase body's elasticity and physical strength. They may be divided into two undergroups: throwing techniques and holding techniques. These may be performed freely or with equipment; Preparation exercises:which have the aim to prepare the body for judo movements; being this sport performed on a mat tatami, it will be necessary to adapt them accordingly, by performing in a standing position, on the back and on the belly. It is always important to keep in mind that falls are also a perfect training exercise.
The grips
During most competitions visually impaired athletes need a guide, or a sound to which to refer to or a time and so on. In this discipline the athlete may perform alone according to his character and temperament.
The athletes establish a contact through the hand grip on opponent's kimono. There is a great variety of grips according to height, body weight, strength, opponent's fighting way.
It is evident that grips are technically fundamental, but in every moment they need to be relaxed and not stiff, in order to function as earphones and to receive as much information as possible from the contact with the other athlete.
Grips have a double function:
active: transfer to opponent's body an impulse which is connected to the throw. The right arm will have the task to convey opponent's body weight, while the left one will accentuate moving action, with a precise directional character; passive: stop impetus and opponent's movement which will perform a throw. The right arm will receive information concerning the direction of opponent's body movement, while the left one will receive information concerning lack of balance's direction.
Of course it will be necessary to study a way to change grips continuously, according to opportunities, trying to use energy the best possible way according to competition's tactic.
One basic principle of this sport is that judo is born from grips.
