lamplight
In order to ensure the clarity of the Olympic TV broadcast images, the illuminance is required to be 1500 ~ 2500 lux, and the illuminance of all tables is the same. If it is necessary to add a temporary light source due to TV broadcast and other reasons, the angle between the light source and the ceiling should be greater than 75 degrees. The illuminance of other parts of the competition area shall not be less than 1/2 of the illuminance of the competition table, and the light source shall not be less than 5 meters from the ground.
Generally, the surrounding area of the venue should be dark, and the illuminance in the auditorium should be significantly lower than that in the competition area, so as to avoid dazzling light sources and natural light without covered windows.
ground
The floor shall be a wooden or movable plastic floor of brand and type approved by ITTF. The floor is elastic, and there are no other signs and signs of movement. The color of the floor should not be too light or too reflective, but red or crimson; Don't use too much oil or wax to avoid slipping.
temperature
The air velocity in the competition area in the exhibition hall is controlled within 0.2 ~ 0.3m/s, and the temperature is about 20 ~ 25 degrees Celsius, or 5 degrees Celsius lower than the outdoor temperature. In addition, I want to know how to play table tennis to improve my physical fitness.
What are the practical skills in table tennis?
1. You'd better loosen the racket when serving.
The plane of the wrist rotation direction is perpendicular to the straight line of the arm. After hitting the ball, you should bump your body slightly, so that you can relax well and return to the standard preparation action. In order to hit your body, your heel should be raised at the moment of hitting the ball. There are four feelings in playing ball: staring at the ball to judge the incoming ball, moving the foot, hitting the ball and restoring it.
2. Laga turns the ball and squats his legs.
When squatting, first step sideways to make way for the kick-off, then squat down with your legs instead of 1 leg arch and 1 leg pedal, lean slightly to one side, relax and sink your right shoulder, and pedal your right leg quickly! When the center of gravity shifts from the right foot to the left foot, don't let your body jump when your right foot touches the ground. You should feel that the center of gravity is moving in parallel.
3, serve action standard specification
One-handed throwing action: the throwing height is greater than or equal to 16cm, and the throwing action should be outside the end line of the table, higher than the table top and vertical. Swing action of the other hand: According to the new rules, it should be higher than the table, and the referee and the opposing athlete in the middle of the two sides should be able to see the action clearly.
4, a quarter of the law
When you start practicing forehand attack, you should remember 1/4. First, the trajectory of arm swing is 1/4, and the racket friction ball is also'1/4' of the ball. The arm swing is relaxed to the starting position according to the original arc of 1/4-coach Lu takes the end line as the diameter in the ball case. Then face the wall, get ready to attack the ball with your own height, draw a horizontal line of 1 with waist height and eyebrow height as the highest point, and draw an arc. This is a frontal projection.
The harder you hit, the more you press down.
The harder you push, the more you have to push the swing down, not up, and the more you have to hold the ball down and lean forward than when you push hard. When you hit the ball, you should bend your wrist a little, so that the ball can go faster.
6. More experienced grinding ratio
When you don't rush, you will feel that hitting the ball forward can make up for the speed, which is a bit like drinking poison to quench your thirst. In fact, hitting the ball too much can easily lead to bad arcs and many mistakes. Moreover, because the rotation is not strong, the forward thrust of the pulled ball is not strong, especially outside the table. Too much friction will lead to full speed and low strength.
7. Pay attention to the power of service
The power of serving, especially the afterburner, is often associated with the consequences of afterburner: either the ball flies out of bounds or the ball bounces too high. But in fact, the short afterburner is short, spinning, low and in good position. Serving a long ball, the ball is long, urgent, turns and falls on the left and right corners, which embodies the artistry and technicality of table tennis. As long as the friction of the impact force is well controlled, the spiral length of the ball rubbing on the racket is appropriately increased, the friction thickness is reduced, and the rubbing time of the ball on the racket is appropriately extended, the effect can be achieved.
8. Pay attention to serve and score directly.
Practice the best service and unique service, such as edge ball, return ball and near-net sideline ball, and score directly at the beginning of the service. It is especially important in the addition and subtraction system to take the initiative and open the score in the opening and middle games.
9, the use of rotating combination
Use the power of joint services to mobilize opponents. For example, serve near the net, short turn, combination of baseline, left, right, near, long and urgent ball often get twice the result with half the effort. For example, serve the ball that turns around near the net without turning around, serve the ball that turns around near the net and serve the "left explosion side spiral ball" to serve the opponent's left line. This rotation combination makes opponents feel difficult to adapt, thus controlling the rhythm of the game and making the attack score frequently.

The ball must not touch anything before it leaves the palm of your hand, nor be blocked by clothes or any part of your body, so that the receiver can't see the whole service process. If it is, it will be judged as a foul.
3. When the ball falls from the highest point, the server can hit the ball, and then the ball first touches the server's platform, then crosses or bypasses the net, and then touches the receiver's platform. If the ball hits the net when serving, it must be served again. In doubles, the ball should touch the right half of the server and receiver.
4. From the start of serving to hitting the ball, the ball should always be above the table, outside the end line of the server, in order to prevent the foul of serving in the table, and it should not be blocked by any part of the body or clothes of the server or his doubles partner, otherwise it will be considered a foul.

2. In doubles, every time the service is changed, the front-end server will become a server, and the partner of the front-end server will also become a server.
The player who serves first in one game should accept the service first in the next game. In the final game of doubles, when one player scores 5 points first, the receiver must exchange the order of receiving the service.
4. In a game, one player in one direction has to change to another direction in the next game. In the deciding game, when one side scores 5 points first, the two sides should exchange places.
