My favourite sport

Volleyball, is a sport where two teams face on a plain field separated by a central network, trying to pass the ball over the net to the ground of the opponents. The ball can be touched or driven with clean shots, but can not be stopped, held, retained or accompanied. Each team has a limited number of hits to return the ball to the opposite field. Usually the ball is hit with hands and arms, but also with any other body part. One of the most peculiar characteristics of volleyball is that players have to be rotating their positions as they earn points. 

The playing field

The playing field where volleyball is a rectangle measuring 18 m long and 9 meters wide, divided into its centerline by a network that separates the two teams. Actually the game is also on the outside, in the free zone, provided that the ball does not touch ground or any other item. The free zone must be at least 3 m, as in international competitions is increased to 5 m on the sidelines and 8 m for the lines. The free space on the track must have a minimum height of 7 m in international competitions up to 12.5 m.
A 3 m of the network, one line in each field defines the frontcourt, are restricted zone where the actions of the players who are currently in defensive roles (backs and sweeper). These lines extend outside the field with dashed lines, and limiting projects representing equally all along the line, even beyond the lines drawn. All lines are 5 cm wide.
