The problem of the distance between the school basketball court and the NBA

The NBA 3-point line is 7.53 meters The school's three-point line is farther than the NBA's free throws, don't you see that the NBA's 3-point line is far away from the 3-second top arc, the school's three-point top arc and the three-second arc basically overlap.

I don't remember it clearly.

In addition to the superb basketball skills of the players on the NBA court, the sports environment of the basketball court is also extraordinary. For example, the court is also very ornamental under the illumination of the lights, and the wooden floor of the basketball hall paved on the ground is also unique. Eurasian sports wood flooring engineer, today to give you science NBA basketball hall wood flooring is good**:

1. Excellent material selection.

The main selection of sports wood flooring materials used in the NBA field is made of maple between 30 degrees north latitude and 40 degrees north latitude, sports wood flooring manufacturers said that only maple wood between this dimension can be suitable for basketball court flooring, because of its good growth environment, the texture is not soft and hard, the texture is clear, and the durability is good, so it is a good choice of materials.

2. Paving in an orderly manner.

Each piece of wood flooring in the NBA court floor is numbered by sports wood flooring manufacturers, and the location of each floor is specific, and the NBA basketball court needs to be renovated and replaced very frequently every year compared with ordinary sports venues.

3. Visually beautiful.

The surface layer of the NBA basketball court floor will look particularly bright under the lighting, giving people the impression that the ground is very slippery, in fact, the surface layer uses a special water-based paint, which can not only maintain the slip resistance, but also maintain the beauty of the appearance. The glossy design is because it can better enhance the visual effect of people watching the game.

4. High degree of professionalism.

For the grade difference of the floor material, its value is also a relatively large difference, the grade selection of the NBA stadium floor is the best, now the NBA event has become a must-see sports event, the international influence is very large, so the planning and construction requirements of the site are becoming more and more stringent, of which the sports wood floor occupies a dominant position.

The basic gum or cement for the school, the NBA uses:

Wooden! Sports wood flooring requires the selection of the surface material of the floor, which must be moderately soft and hard, and the amount of deformation is small. Tree species with a long fibrous structure (not easy to thorn) to avoid injury to athletes**. There are four kinds of sports flooring: maple, oak, beech and ash, which have been proved by practice for a long time, and maple is the most ideal.

According to the needs of customers, the company has various types of sports flooring at home and abroad.

Maple Flooring Performance:

1. Good performance on the ball;

2. It can effectively resist earthquakes, reduce vibration, and sound insulation;

3. The unique elastic cushion provides unique elasticity and bears heavy pressure for the hard maple floor, reducing the shock injury caused by the bounce on the floor.

The material of the venue, the material of the floor, the atmosphere of the venue, and the ambient temperature are all different.

The NBA is made of wood, but the material is very good, I don't know how many times better than the CBA, and it is comparable to the school?

Basketball court size drawing.

FIBA standard: The entire basketball court is 28 meters long and 15 meters wide. Long ratio: 28:15. The lower edge of the hoop is meters from the ground.

1. Stadium: It is a rectangular solid plane with no obstacles. For major FIBA official competitions, the court is measured from the inside of the boundary.

For all other matches, the appropriate FIBA department has the right to approve existing courts within the following dimensions: 4 metres in length and 2 metres in width, provided that the changes are proportionate to each other. The ceiling or minimum obstacle property height is at least 7 meters.

The lighting of the stadium should be uniform and the luminosity should be sufficient. The lighting equipment shall not be placed in such a way as to obstruct the vision of the team members. All new courts must be sized in accordance with the requirements set out in the main official FIBA competitions:

It is 28 meters long and 15 meters wide.

2. Lines: The width is meters (5 cm).

1) Boundary: The boundary of the stadium is at least 2 meters away from spectators, billboards or any other obstacles. The boundary on the long side of the pitch is called the sideline, and the boundary on the short side is called the end line.

2) Middle line: Draw a line parallel to the end line from the midpoint of the side line called the middle line; The midline should be extended by 15 cm (15 cm) beyond the edges on each side.

c) Free throw lines, restricted areas and free throw areas:

1.The free throw line should be parallel to the end line, and its outer edge should be one meter away from the inner edge of the end line; The length of this line is meters. Its midpoint must fall on the imaginary line connecting the midpoints of the two end lines.

2.The ground area formed by drawing two lines from each end of the free throw line to a place of 3 meters from the midpoint of the end line (both measured from the outer edge) is called a restricted area. If you shade inside a restricted area, it must be the same color as the inside of the center circle.

3.The penalty area is a semi-circle drawn outside the restricted area with the midpoint of the free throw line as the center of the circle and the meter as the radius. The semicircles in the restricted area should be drawn as dotted lines.

4.The position areas on either side of the penalty area are used by the players when taking the free throw. Here's how to draw it:

1) The first line is measured along the edge of the end line along the edge of both sides of the penalty area.

2) The width of the first position zone is m (85 cm) and is connected to the beginning of the neutral zone.

3) The width of the neutral zone is 040 meters (40 cm) and painted in the same color as the other lines.

4) The second position zone is adjacent to the neutral zone and has a width of meters (85 cm).

5) The third position area is adjacent to the second position area and is also meters (85 cm) wide.

6) All the lines used to draw these location areas have a length of 010 m (10 cm) and perpendicular to the outside of the penalty area touchline.

4) Middle circle: The middle circle should be drawn on the first side of the court, with a radius of meters, measured from the outer edge of the circle. If you shade the inside of the center circle, it must be the same color as the inside of the restricted area.

5) 3-point shooting area:

1.Respectively meters away from the edge line, two parallel lines are drawn from the end line;

2.An arc (semicircle) with a radius of meters (measured to the outer edge of the arc) intersects two parallel lines;

3.The center of the arc should be at the intersection of the vertical line of the center of the opponent's basket and the ground. The distance between the center of the circle and the midpoint within the end line is meters. Note: If the width of the pitch is less than 15 meters, the arc will still be drawn according to the above metre radius.

Basketball court standard size.

The international basketball court is slightly smaller, 28 meters by 15 meters, the distance between the three-point line is meters, and the free throw area is trapezoidal, and the part of the sideline is wider than the free throw line. The height of the hoop (basket) on all courts is meters. The college basketball court in the United States is about the same size, but the distance between the three-point line is shorter (6 meters).
