VolleyBall

The regulation volleyball court is a rectangle, 18 meters by 9 meters divided into two equal squares by the center line. Above the center line spans a taut horizontal net that is 2.43 meters above the court. The net is 9.5 meters long, and 1 meter deep. The mesh features squares that are 10 centimeters wide. The volleyball is 65-67 centimeters in circumference and 250-260 grams in weight. The outside is leather, over a bladder of rubber or similar material. It must be of one color and cannot have any laces. Volleyball uniforms consist of a vest or jersey, shorts, kneepads, and rubber or leather shoes without heels. Team members wear the same color and may play in numbered tracksuits during cold weather.

Play begins with the serve of the ball, and players take turns rotating around the court so each player gets a chance to "serve" the ball. The ball may be "served" when the server bumps the ball into play across the net with a fist, or throws the ball into the air and strikes it with a hand or arm to bump it across the net into the opposing team. Members of the opposing team then attempt to "save" it from hitting the ground and loft it for a teammate to play. Each team is allowed to contact the ball three times before returning it over the net. No individual may hit or be touched by the ball twice in succession, and the ball must never be held, lifted, or carried. Play continues until one team allows the ball to touch the ground in its own court or fails to correctly return it. A point is rewarded to the serving team if the opposing team makes the fumble. If the serving team incurs the fumble, the receiving team is then allowed control of the ball and becomes the serving team.
