The rules establish an understanding for competition. In sports, regulations specify what is and is not permitted to happen on and off the court. Rules regulate everything from correct uniform wear to how to maintain score during games of various levels of play. In volleyball, the most important rule is that there should be two players per side on the court at all times. This means that if you are up against one opponent, your partner should be off the court waiting for another chance to hit the ball. If both players are on the court, it's better for them to be fighting each other! Other important rules in volleyball include: players must have their hands behind their backs throughout the game; players can't touch the floor with their legs; and players must follow through with the swing of their arms when hitting the ball. These rules are just some examples of how rules affect the outcome of a match. In general, playing by the rules ensures that the game progresses efficiently while keeping it fun for everyone involved.
