Serve execution

An unwritten rule in table tennis says that 50% of the wining point is the execution of a good serve. In spite of the strict laws which limit the effectiveness, the serves provide great advantage in the modern table tennis. Serve is considered as one of the most important part of the daily practice. Many top players spent a lot of hours developing new serves. Three times per week for 1-2 hours each is a standard for top class players. Each player (basic and medium stage) has to learn at least 6-7 different serves and use them alternatively during the match according to the pre-determined tactic.

The factors which affect the execution of a serve are:

The grip. Grip flexibility is important for the wrist movement.
The distance of the player from the table during the serve.
The ball throwing. Different speed is gained from a high toss serve in comparison with the low toss serve.
The angle of the racket during the impact. Different angle gives little or more spin.
The speed of the arm and the wrist movements at the impact phase which affects the speed of the ball.
The compination between arm, wrist, feet and waist movements at the impact phase.
The location where the ball bounce at the server's court affects the bounce on the receiver's court.
The concentration of the player.
The type of rubber and the racket.

Some points which need special attention are:

The serves have to send to the weaker side of the opponent in order to make an effective "third ball attack".
The server has to change his serves constantly. This is good if we want to confuse the opponent. It gives us also the opportunity to find the "effective serve" which will make the point for us.
Special and tricky serves are for the crucial moments of the match.
