Volleyball

Volleyball is a ball game beating against the ball over a net.
It is performed in two teams of one team six people or nine people.
9 system is held as "mom valley" frequently mainly in Japan, but the international matches are performed in 6 system without spreading worldwide.
It is performed with one set of 25 points (to five sets of /5 sets match eyes, 15 points) in 6 system.
It is translated as volleyball (sudden yes) in the Japanese and kanji zone.
The rule of these days was very simple and divided the people who gathered for a match into two teams of the same number and hit the ball, and the which dropped a ball said with a defeat.

At first the volleyball spread out in the American whole land through YMCA which each place was dotted with, and it was introduced to Cuba in Canada, 1906 in 1900.

The number of people of the team was 16 people first, but I turned into 12 people, and a near thing was completed for 9 system volleyball as of nine neighbors successively.

The number of people of the team was decided on six people in these days, and the thing which was near to current 6 system volleyball was already completed.
The central committee of the Russian Communist Party raised a slogan of "1,000,000 volleyball" in the Soviet Union in 1925 and established association of Soviet Union volleyball and wrestled for development of the volleyball in earnest.

International Volleyball Federation was formed in 1947, and I revised an American rule, and an international rule was completed.

The No. 1 volleyball world championship was performed in 1949.
It was 1951 that Japan joined the International Volleyball Federation.
The mainstream of the Japanese volleyball is 9 system, and the 6 system volleyball used in an international match may gain the favor in those days because it was not well known.

Technology development came to be pushed forward to be opposed to Soviet height and power in the Eastern European counties when 1950's began.
Czechoslovakia in particular started new technical development in sequence and thought out the tactics such as a swift attack, a feint, the blocking out.

A medal sport increased volleyball from the Tokyo Olympic Games in 1964.
It was from these days that combination valley was established, and technology peculiar to Japan such as rotary receiving, delayed spiking was thought out.

I tended to treat it by the physical education of a junior high school / the senior high school as sports to feed sense of cooperation in Japan and generally settled.

International Volleyball Federation decides the rule of 6 system, and association of Japanese volleyball decides the rule of 9 system.
I describe a rule of 6 system here.

I use long side 18m, the court where a rectangular line was drawn into of narrow side 9m.
A net is set up in the form to divide a coat into two centrally.
As for the height of the net, 2.43m, a girl are fixed for 2.24m a boy.
3m have a line called an attack line from a net each.
As for the space (a free zone) more than 3m, the height to a ceiling, more than 7m are needed outside the coat.
