The volleyball libero is a back-row defensive specialist who cannot block or attack balls above net height and cannot serve in international play. The libero's job is to receive serves, dig hits, pass and occasionally set. The position emerged internationally in 1998 to improve defense and ball movement. "

The basic rules of volleyball are well-known in terms of legal and illegal hits. However, there are special situations that have led to the creation of new rules to define what is and is not an acceptable hit.

The most effective volleyball players have a powerful arm swing, hitting the ball with more force and gaining greater thrust on jumps. During the course of a game, you use your arms to serve, set, hit, spike and block -- fundamental maneuvers for successful play.

Although the phrase "there is no I in team" is often overused, it resonates strongly when you talk about volleyball squads. University of Northern Iowa volleyball coach Bobbi Petersen, in an article in the "Waterloo Cedar Falls Courier," said, "Volleyball is one of the most team sports there is.

In volleyball, vertical jump measurements are important factors that coaches use for recruitment to compare players or to evaluate the improvements of a player. There are two vertical jumps in volleyball: block jump and approach jump.

Here’s a fun thought: Next time you watch the fast-paced action of a volleyball game, consider how many laws of physics are being demonstrated on the court. For example, every movement by the ball or the athletes illustrates one of Newton’s three laws of motion: inertia, acceleration and action-reaction.

In volleyball, a team of six players works together to return the ball to the opposing team’s side of the net in three hits or fewer. Players may contact the ball with any part of the body during a hit, but if they violate other rules about playing the ball, they risk losing points for their team.

Like a basketball point guard on a basketball team or a football quarterback, setters are the leaders on the court for their volleyball team. Just as point guards and quarterbacks call plays for their offense, setters communicate plays and strategies to teammates for each point.

A set is a quick motion that positions the volleyball for a hit. The ease with which setters put the ball up in the air is deceiving. Setting a volleyball correctly is the most difficult skill to learn in volleyball.

Knowing and understanding the rules of volleyball is essential for all players, coaches and officials to be successful in the game.

Volleyball is a game of skill and ability which relies on each player's ability to direct the ball to areas of the court where their opponent can not reach it before it strikes the floor. This process relies on different types of hits using the hands and forearms.

Though the whole point of volleyball is to get the ball over the net and into the opponent's court, there are occasions when a player may need to reach or step under the net to save a point. The International Federation of Volleyball has very specific rules about going under the net.
