What's the tennis court like?

The tennis court is a rectangular court. Tennis courts come in two standard sizes. One is a single tennis court. Its standard size is 23.77 meters long and 8.23 meters wide. The other is a doubles tennis court, the standard size is 23.77m long and 0.97 m wide/kloc-0.

In addition, there should be space behind each end line and sideline, with the end line space not less than 6.40m and the sideline space not less than 3.66m.. There is a net in the middle and it is hung on a rope or wire rope with a maximum diameter of 0.8 cm.

The ground of the mainstream tennis court is an elastic acrylic court with no obstacles. The ground of the tennis court also has plastic, red soil, artificial grass and wooden floor. Whether using wooden floor or synthetic floor, it is necessary to ensure that athletes will not feel too slippery or too sticky during the competition and have certain elasticity. But pay attention to the smoothness of the ground to prevent injury accidents.

Extended data:

Tennis courts can be divided into outdoor and indoor, and have various court surfaces. This will be determined by economic factors. For example, lawn tennis is the most basic outdoor venue, but its establishment and maintenance costs are too expensive, so it is now replaced by an artificial court, which is cheaper and easier to maintain. In addition, a clay court is popular in Europe, and its French Open is such a court.

Lawn court is a kind of venue with the longest history and the most traditional significance. It is characterized by low friction between the ball and the ground, fast rebound speed of the ball, and very high requirements for players' response, agility, running speed and technology.

Therefore, the grass is often regarded as the world of "offensive tennis", and various online offensive tactics such as serving and following the ball are almost regarded as the magic weapon to win on the grass tennis court, but it is difficult for the bottom line players to do it on the grass tennis court.

However, due to the extremely high requirements for the characteristics and specifications of grass, coupled with climate restrictions and high maintenance costs, it is difficult to popularize it all over the world. At present, almost all the few lawn professional tennis tournaments are held in the British Isles every year, and the time is concentrated in June and July. Wimbledon is the oldest and most prestigious tournament.

More accurately, it is a "soft court", and the most typical representative is the French Open Tennis Tournament on clay court. In addition, all kinds of common sand and mud can be called soft soil foundation.

This kind of stadium is characterized by high friction between the ball and the ground and slow ball speed. Players will have a lot of sliding space when running, especially when stopping and turning back, which determines that players must have better physical fitness, running and moving ability and more tenacious will quality than other courts.

It is a great test for players to fight for the bottom line in this kind of venue. Players usually have to pay several times of sweat and patience to deal with their opponents at the bottom line. Winners are often not aggressive servers, but people struggling at the bottom line.

Hard ground site

Most modern competitions are played on hard court, which is also the most common and common venue. Hard court is generally paved with cement and asphalt, and the surface is coated with red and green plastic. Its surface is smooth and hard, and the ball bounces regularly, but it bounces quickly.

Many excellent tennis players think that hard court tennis is more explosive and hard court is dominant in tennis matches, so we should pay special attention to it. It should be noted that the hard court is not as elastic as other courses, and the surface reaction is strong and stiff, which is easy to hurt players, and this kind of injury has cost many excellent tennis players a lot.

Carpet field

As the name implies, this is a "portable" rollable tennis court with a plastic surface and a nylon woven surface. Generally, it can be pasted on the ground of asphalt, cement and concrete foundation with certain strength and hardness with special glue.

Some of them can even be directly laid or bonded on any supporting ground, which is convenient for rolling, suitable for transportation and very adaptable, and can be used indoors, outdoors and even on the roof.

The speed of the ball depends on the smoothness of the field surface and the roughness of the carpet surface. In terms of maintenance, this kind of site is also very simple, as long as the ground is kept clean, undamaged and free of water (equipped with corresponding drainage facilities).

Scribing method

(a) single, double venue marking steps

First, choose the position of the net, draw a straight line (reference line) with the length of 12.8m, mark X at the midpoint, and then measure from this point to both sides, with the fixed points as follows:

The distance between point A and point B is X4. 1 1 m, where the net intersects the singles sideline. N points and N points are the positions of singles columns, and each column is X5.03 meters away from the midpoint. Point A and point B are X5.49 meters away from the midpoint, which is where the net meets the sideline of doubles. N points and N points are the positions of doubles net posts, and each position is X6.40 meters away from the midpoint.

Nail point A and point B and connect them with one end of the measuring ruler respectively. An AC line (half-court diagonal) is formed from the snack amount 16. 18m at point A, and a BC line (half-court sideline) is formed from the snack amount 1 1.89m at point B.. Then, tighten the AC line and BC line so that the two lines intersect at point C, that is, the half court. Reverse measurement can find another corner point d.

Whether the above operation is accurate or not, you can check the length of the CD line, which should be10.97m long. At the same time, the midpoint J and the sideline of singles can be marked, and the distances between points C and D are 1.37 meters respectively. All points F, H and G of the center line and the service line can be drawn at the distance of 6.40m from the net on bc, XJ and ad lines respectively. Draw the court on the other side of the net in the same way.

(2) Marking steps of singles special session

A, b, c, d, the outer lines don't need to be drawn. You can also add nails at A and B, connect them with straightedge to replace A and B respectively, and then use the lengths of 14.46m, 1 1.89m to find out the two corners C and D of the singles end line. The net posts are in N and N, and the singles net with a length of 10 meter should be used. ?

(3) In the venue where singles and doubles are held at the same time, if the doubles net is hung in singles, the net must be propped up by two columns with the height of 65,438+0.07m in N and N, and the diameter or side length of the columns shall not exceed 7.5cm, and the center of the columns shall be 0.965,438+04m away from the outer edge of the singles sideline. These two pillars are called "click pillars". In order to facilitate the placement of singles columns, N points and N points on the court should be marked with white dots.
