If you are a middle blocker and begin the match in the left-front position, you can switch to the middle position immediately after the serve is touched. If you change positions before the ball is served, you will be called for an overlap or being out of position, which will result in a point for the other side.
Generally speaking, players who know the court well tend to stay in one specific spot on it. But since there are so many different options and opportunities for things to happen in a volleyball game, it's important for players to be flexible and able to adapt to what happens on the court.
For example, if the opposing team has a player who is more comfortable as a setter but also knows how to hit the ball over the net, they will usually play around that fact by putting themselves in setting positions when necessary. This allows them to use their best skill set and not be limited by where they choose to stand on the court.
Players should also be aware of where their teammates are on the court at all times. For example, if one defender gets beat off the block, the other defenders should be ready to step up and help her out. Similarly, if one attacker starts moving towards the middle of the court, the others should make room for her to get open shots.
Following the serve, players may walk around the court to any of the volleyball rotations they like. For example, if your middle blocker is in the "left front" position, they can transition to the "middle front" position after the serve. Players do not have to stay on the same line as their original position; for example, a left-handed player could go all the way over to the right side of the court and still return serves from that side.
However, once players enter the service box or behind the net, they are no longer able to change positions. For example, if a player enters the service box but then moves to the "right rear" position, they cannot switch back to the "right front" position when serving again. Instead, they would need to start over on the other side of the court.
This rule exists to prevent players from gaining an advantage by changing positions after hitting a serve. If a player can decide where they want to go on the court without being hit, why not use that option to your advantage? However, it also prevents them from running down shots off the sideline or out of bounds. In these cases, the player would need to start over.
Overall, players can move anywhere on the court except during service.
If you play in the middle, your starting position is directly in front of the setter—typically just to the left of the center of the court. Before your team serves the ball, find your opponent's front row batters and alert your teammates to their presence. When your team gets the serve, try to put the ball in the opposite corner where that batter stands rather than letting it run down the middle of the court. Middle hitters usually have good reach and can hit balls over the net or into the audience.
There are two types of middle hitters: those who will get any ball served to them and those who don't. If the server knows you won't attack anything but return attacks, then he or she will usually keep the ball low and away from mid-range shots so you can't hit it. Otherwise, you might be able to get some kills if the server makes a mistake.
In general, middle hitters like having the opportunity to choose when they go for the kill and when they don't. They also like the fact that they can protect the sidelines by hitting over the net or into the audience. However, since most teams have at least one attacking player, middle hitters often end up with only defensive opportunities.
Even though middle hitters don't score many points, they're important members of the team. You need someone who can get all the balls served to them so the other players can attack.
After the ball is served, the rules of the game enable players to exchange places in the same area of the court (e.g., front or back). This allows teams to move their players into different positions, either to maximize their own capabilities or to offset the opposition's strengths. For example, if your team has a hitter who is good on the block but struggles with overhead shots, you could have him move to the sideline where he wouldn't be required to hit balls that are out of reach.
Here are some other reasons why players might switch roles after serving:
Blocking: A blocker uses his/her body to protect the net by blocking shots from going out of bounds. Blocks can be done standing up or kneeling. A player might also use his/her body to block shots while jumping for balls hit near the net.
Setting Balls: The setter is responsible for setting the ball within the court so that it will be in play when it reaches the opposing team. Setters can be either male or female. Males typically set the ball higher than females which enables them to see over the net.
Spiking: A spiker hits the ball with great force so that it goes as far as possible into the stands. This is one of the most dangerous positions on a volleyball team because the player is exposed during every point of the game.
The server must serve from behind the finish line until contact is made. Balls can be served both underhand and overhand. Before serving, the ball must be readily seen to opponents. A serve may skim the net and fall to the opposite side for a point. If it does not hit the net, it is out.
As soon as the server has served the ball, he or she must race to the other end of the court to receive his or her own service. The server cannot wait at the net to receive his or her own service if the opponent is ready with the ball. Once the server reaches the end of the court, he or she has two options: either return the ball to the center of the court or attack the opposition's ball. It is important to remember that you cannot be on the same side of the court as your partner when returning a service or attacking an opponent's ball. You need to be on different sides so that you do not block each other's shots.
Finally, the server must always remain behind the baseline while the ball is in play. He or she may leave the court during changeovers if there is no risk of being hit by a shot.
These are the basic rules of serving in volleyball. As you can see, it is very important that you follow these instructions carefully if you want to achieve success on the court.
