It's a half-court basketball, half of the standard basketball court. The length and width are 14m * 15m.
Extension:
FIBA standard: The whole basketball court is 28m long and 15m wide. Long scale: 28: 15. The lower edge of the ring is 3.05 meters above the ground.
First, the stadium: it is a rectangular three-dimensional plane with no obstacles. For the main official matches of FIBA, the measurement of the stadium should start from the inner edge of the boundary. For all other competitions, the appropriate department of FIBA has the right to approve existing courses that meet the following dimensions: the length is reduced by 4 meters and the width is reduced by 2 meters, as long as the changes are proportional to each other. The ceiling or the lowest obstacle is at least 7 meters high. The stadium lighting should be uniform and the brightness should be sufficient. The placement of lighting equipment shall not interfere with the line of sight of players. The dimensions of all newly-built venues should meet the requirements of FIBA's main official competitions: length 28m, width15m.
Second, the line: the width is 0.05m (5cm).
(1) Boundary: The boundary of the stadium should be at least 2m away from spectators, billboards or any other obstacles. The boundary of the long side of the stadium is called the sideline, and the boundary of the short side is called the end line.
(2) midline: draw a line parallel to the end line from the midpoint of the sideline, which is called the midline; The center line shall extend 0.15m (15cm) to the outside of both side lines.
(3) Free throw line, penalty area and penalty area:
1. The free throw line should be parallel to the end line, and its outer edge is 5.80m away from the inner edge of the end line; The length of this line is 3.60 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 both ends of the penalty line to the place 3 meters away from the midpoint of the end line (all measured from the outer edge) is called the restricted area. If it is colored in the restricted area, its color must be the same as that in the middle circle.
3. The penalty area is a semi-circular area with the center of the penalty line as the center and the radius of 1.80m outside the penalty area ... The semi-circle in the penalty area should be drawn as a dotted line.
4. The position areas on both sides of the penalty area are used by players when making free throws. The painting method is as follows:
(1) The first line is 1.75m from the inner edge of the end line, measured along the side lines on both sides of the restricted area.
(2) The width of the first location area is 0.85m (85cm), which is connected with the starting point of the neutral area.
(3) The width of neutral zone is 0.40m (40cm) and painted with the same color as other lines.
(4) The second position area is adjacent to the neutral area with a width of 0.85m (85cm).
(5) The third location area is adjacent to the second location area, and its width is also 0.85m (85cm).
(6) All lines used to draw these positions are 0 0. 10/0m (10cm) long and perpendicular to the outside of the restricted area.
(4) Middle circle: The middle circle should be drawn in the center of the court with a radius of 1.80m, measured from the outer edge of the circumference. If it is the color in the middle circle, it must be the same as the color in the restricted area.
(5) Three-point shooting area:
1. Draw two parallel lines at the end line 1.25m;
2. An arc (semicircle) with a radius of 6.25m (measured to the outer edge of the arc) intersects with two parallel lines;
3. The center of the arc should be at the intersection of the vertical line at the center of the opponent's basket and the ground. The distance from the center of the circle to the midpoint of the inner edge of the terminal line is1.575m.. Note: If the width of the court is less than 15m, an arc will still be drawn according to the above radius of 6.25m ..
Standard size of basketball court
Venue size: First of all, a standard basketball court is 28m long and15m wide according to international standards. In addition, the length of the site needs to be about 34 meters, which can be adjusted according to its own site size to keep the size in direct proportion.
The lower edge of the backboard is 2.9 meters from the ground and the basket is 3.05 meters from the ground.
Rack placement: the base of the rack is generally 2m× 1m, and the length of the probe arm is between1.8m-2.25m. According to the requirements, the probe arm needs to extend into the site 1.2m, and the general site boundary line is 5cm. If the probe arm is calculated as 1.8m, the ball rack should be placed 55cm away from the ground wire of the site.
Safety: Two parts of the rack are prone to accidents. First, the supporting feet of the base are generally cast iron, but they are easy to corrode. All the good ones are cast steel, which greatly improves the durability and safety.
Second, the basket, the bad basket will lose its elasticity after being used for a long time, and will fall off because of the thin material for a long time. Many of them are cast steel, and reinforced springs are used, which is very safe.
Expanding reading: five defensive elements in basketball teaching
First, move
The attack on the basketball court is competitive, and the attacking players rely on their own personal skills or team tactics for sports operation. Therefore, as passive defenders, they must also move their defense because of the movement of the attacking players.
Take man-to-man defense as an example. When you defend the ball bearer, you must follow the defender closely and don't let him have a chance to break through the shot. In order to get rid of your defense, the ball bearer will also conflict and shake from side to side. At this point, if the defender does not master certain moving skills, he may be easily removed.
When facing the players without the ball, the irregular running of the players without the ball needs to cooperate with the movement of the defenders and exercise their body movement skills. Only by persisting in training can we improve these defensive skills.
Second, the body.
Obviously, your body plays a defensive role. If you are stronger than your opponent, you will easily be in an oppressed position. If you are faster than your hands, you can have an advantage when moving. When you bounce better than your opponent, your air superiority is reflected. You can exercise more strength, speed and bounce at ordinary times.
Third, consciousness.
In my opinion, defensive consciousness includes the choice of defensive mode and the instantaneous consciousness transformation from attack to defense. When your own attack is completed or terminated by the other side, you should quickly return to the defensive state.
It's not too late to enter the defensive state at this time. You can sneak attack at your convenience. Of course, this is all a personal sense of defense. Another point is the overall defensive awareness. Overall defense is for a team. What if the other party uses a pick and roll? You should immediately change your defense or keep the original marking to keep up with your own people quickly. If the teammate's defense breaks through the teammate's defense, it is necessary to make up the defense.
Fourth, judge
Judgment is an abstract thing. There may be only a few tenths of a second for you to make a judgment. For example, when the opponent makes a threatening action, does he shoot, pass the ball, or break through consciousness? You must make a judgment in the shortest time and choose the most appropriate defense method.
How should the opponent interfere and block when shooting? This is all a momentary reaction, and another important aspect of judgment is the judgment of fake action. Fake action is a special way for attacking players to deal with defense. Sometimes, if the other person wants to throw a fake action, you must not jump easily. Sometimes, if you are shaken by your opponent, you are more likely to fall into the trap of cheating and foul.
The dribbler's defense should not look at the opponent's ball, feet and face, but should focus on the attacker's waist, which is the least likely to fake, pestering him and not giving him a chance to break through the shot.
Judgment, like consciousness, is very dependent on experience, which requires players to think more and sum up the rules in peacetime. This requires a certain amount of competition experience.
Fifth, will
Defense should never give up, stick to the end and never relax. If you have been defending well at first, but you relax in the last few seconds because you want to and your opponent scores, it will be fatal.
Because that's the same as not taking preventive measures, the previous efforts are all in vain, so no matter how tired you are in the end, you must grasp it. Only by sticking to the last second can you win. In fact, this is the same as being a man, and we must have the spirit of perseverance.
How to buy basketball
1, filament winding
Brand basketball only uses special nylon yarn with very good flexibility, which is evenly wound with precision special basketball winding machine, and the length can reach 2 kilometers, which makes the basketball bounce more textured, the ball flies and rotates more stably and accurately when shooting, and the basketball is more firm and not deformed.
2. epidermis
High-quality basketball adopts leather specially made by professional manufacturers.
3. Inner container
Big brands use imported rubber, which is the same material as high-end automobile tire lining. After strict patented technology processing, the bounce is soft and stable, which is the internal source of the delicate feel of high-quality basketball. A good feel will certainly bring good self-confidence.
4. Texture
The most important criterion to distinguish between good and bad basketball is the material of basketball. Because the material of basketball determines the feel of our play, it also partially affects the "bounce" of basketball.
A good basketball surface will have a little elastic feeling, and the rubber-like skin will have a little sticky feeling to ensure that it will not slip when catching the ball. Beginners may not have a clear impression of sticky hands and elasticity when buying. It is recommended that experienced friends help to try the feel. Specific requirements can be measured by whether you can easily master basketball.
5. Energy efficiency
The easiest way to test the energy efficiency of basketball is to lift the basketball to 1.8m (from the bottom of the basketball) and then drop it by throwing the ball. If the ball falls behind for the first time, the rebound height reaches about 1.2m, which proves that the elasticity and energy efficiency of basketball are good. The energy efficiency of basketball is also one of the main standards to judge the quality of basketball.
6. Difficulties
Some friends occasionally hurt their fingers when playing basketball. When you buy basketball, you can try the hardness of basketball by several simple dribbling methods. if
How to play basketball well
Dribble technical movements include body posture, arm movements, ball dropping and hand-foot coordination.
Body posture
Spread your feet back and forth or left and right, bend your knees slightly, lean forward slightly, look up at the front, and lift the ball horizontally without dribbling. When dribbling, the joints of lower limbs change with the height of dribbling.
Movement of hands and arms
When dribbling, the five fingers are separated to expand the control area, and the palms are empty. When dribbling, use wrist and finger strength, forearm or upper arm and other different parts to dribble in different ways. When pressing the racket ball, you should meet the ball up and down, try to prolong the time of controlling the ball and protect the ball. Press the top of the racket ball if the dribble is in place, and press the back top of the racket ball when dribbling forward.
The impact point of the ball
Under normal circumstances, the ball will fall about 20CM in front of the dribbler's ipsilateral foot. The faster the speed, the more forward the ball falls. In active defense, the dribbling point should be on the side or back of the body to protect the ball. The drop point of the variable dribble is basically in front of the side or the opposite side. Dribble under your legs. The landing point is located in the middle of the crotch.
Hand-foot coordination
When dribbling, the moving speed and dribbling speed should be coordinated to maintain a reasonable rhythm. Pay attention to the position of the racket, the choice of the landing point and the use of strength. The faster you move, the lower you press the ball, and the farther you land, the greater the rebound. Generally, dribble in a straight line, dribble once and run two or three steps.
Skills of playing basketball
1, the center of gravity should be low and steady when dribbling, and the dribbling height should be below the waist. Watch the ball from the corner of your eye to prevent it from hitting your feet. You should skillfully cross the ball with your hands, hit the ball with your palms down, and don't turn your wrists.
A good dribbling technique should be that the ball follows you like it "sticks" to the body, not that you run after it. You can practice dribbling with bamboo poles as people.
2. Changing the direction of dribbling is a common skill and a practical skill. It is to change the direction quickly when dribbling, so that the opponent is caught off guard, and some can even shake the other side, making you pass easily.
Pay attention to the usual practice of dribbling under the leg, dribbling behind the back and crossing dribbling, which is a necessary skill to complete the change of direction dribbling. Keep your body down, improve the dribbling speed and try to find friends to practice in actual combat.
3. When passing the ball, put your hands on your chest, keep your fingers apart naturally, hold the ball with your palms outward, bend your wrists backwards, keep your legs apart naturally, shoulder-width apart or lunge in tandem, keep your center of gravity steady, and look straight ahead (you'd better learn to look six times).
Directionality is very important when passing the ball. This seems simple, but it is not. When you see a teammate's position, you will pass the ball in his direction, sometimes it will not reach the designated position or be intercepted by the opponent, because most players in the game are always moving, so it is impossible to pass the ball directly. They should have radians, judge the players' direction in advance and pass the ball in advance.
In addition, when passing the ball, the strength should not be too great or too light. Passing the ball too hard or too fast will make it more difficult for teammates to catch the ball and easy to lose it. Short pass or slow ball speed is easy for the other side to steal.
5. Before shooting, you should straighten your posture. When holding the ball, the right hand is dominant, and the left hand is auxiliary (the opposite is true for people who are used to using their left hands). Hold the palm of your right hand and ask for it, and the five fingers will naturally separate. The joints of armpit, inside elbow, back of right hand and forearm should be at right angles or close to right angles.
Put your left hand slightly on the edge of the basketball to ensure the stability of the basketball. Keep your upper body straight, don't shrug your shoulders, and your feet will land naturally. The distance between your feet is shoulder width.
6. Before the layup, lower your body's center of gravity, dribble less than your waist, keep your body stable and keep your upper body straight. When running, lean forward as far as possible, slap the basketball with your palms down, and don't flip your wrists. The basis of three-step layup is to practice the basic skills of shooting, especially shooting under the basket. When pitching, use your hands evenly, gently and flexibly.
7. When pitching, you should also pay attention to the strength of the right hand pushing the ball forward and the running arc of the ball. The strength of a general right-handed shooter depends on the distance from your position to the basket. When pitching, you should stir the ball with your palm and let the basketball spin in the air, so that the hit rate is higher. After throwing the ball, the right arm should be straight and the arc of the basketball should be higher, which can improve the hit rate, that is, throw the ball as high as possible.
What are the advantages of playing basketball?
1. Eyes: People who insist on playing ball will look straight into the distance for about 1 hour every day, which is a good relaxation for their eyes. If you have school-age children at home, you can let him play ball every day, and the chance of myopia will definitely decrease.
2, neck, shoulders, spine: people who often sit in front of the computer, cervical vertebrae, shoulders will have some problems more or less. The correct playing posture requires the back to be straight and relaxed, and long-term persistence will greatly improve the discomfort of cervical vertebrae and shoulders.
3. Heart: Sticking to playing ball will make your heart and cardiovascular system powerful. When the maximum oxygen uptake increases, the oxygen delivered to various organs of the body increases greatly, and the working quality of various organs naturally improves greatly. In addition, basketball will also accelerate blood circulation, so that the coronary artery has enough blood to supply the myocardium, thus preventing various heart diseases. Through whole body exercise, it can promote venous blood to return to the heart and prevent venous thrombosis.
4. Blood: With a strong cardiovascular system, the blood quality of runners is better than that of ordinary people. The adaptability of the body to playing basketball for a long time can improve metabolism and reduce blood lipid and cholesterol levels.
5. Lung and respiratory system: Long-term basketball exercise can strengthen lung function and increase vital capacity-playing basketball for a long time can develop lung respiratory muscles, make the amount of ventilation increase and enhance lung function. Personally, I have seasonal rhinitis attacks every autumn, which is very torturous, but I haven't relapsed since I started playing this year. I wonder if it matters.
6. Liver: When I was in the physical examination, the physical examination doctor called the intern to the front and said, look, this is a healthy liver with clear veins on the surface, which is rare now. Playing ball to eliminate fatty liver has been verified by many golfers and is very effective.
7. Abdomen: A flat abdomen or obvious abdominal muscle groove is the dream of many people. Many fitness coaches' suggestions and exercises, such as the abdominal ripper, can help you make your abdominal muscles stronger, but you still need aerobic exercise like basketball to get rid of the thick fat package outside your abdominal muscles. Of course, we should stick to it, because belly is the most cunning, and if we relax a little, we will fight back.
8. Waist and hip: The body change caused by playing basketball is first reflected in this position. Many golfers have had this experience. After playing for a while, I didn't lose weight obviously, but my figure improved obviously, especially the waistline became more beautiful.
9. Knee: Some people say that playing basketball only hurts one knee, which makes sense. Most people who insist on playing ball are more or less troubled by knee injuries. But I learned from the communication with many golfers who have played for more than ten years that they will encounter the same problem when they first start playing basketball. Some people hurt their knees even if they play slowly, but with the gradual accumulation of playing and strength exercises, their knees will become stronger and stronger.
10, Muscle: People who often play basketball, besides looking firm and elastic, muscle tissue will also change, and the distribution of capillaries in a certain volume of muscle will greatly increase, making the use of oxygen and nutrients more efficient and comfortable. I don't know if it has something to do with the cold tolerance of basketball players.
1 1, Stomach: Playing basketball makes people full of optimism, which helps to increase appetite, strengthen digestion and promote nutrient absorption. Of course, what is more enviable is how to eat without getting fat, haha.
12, Muscles: Playing basketball for a long time can strengthen the respiratory muscles, heart muscles, neck muscles, chest muscles, arm muscles, waist, buttocks, thighs, calves, feet and other parts of the lungs, making it difficult for muscles everywhere to accumulate metabolites such as lactic acid or carbon dioxide. Playing basketball can be said to be the first choice of all sports, which will have a positive impact on your participation in other sports.
13, skeleton: playing basketball for a long time can improve the strength of each joint and the softness of ligament; And increase the strength and density of bones to prevent people from suffering from degenerative osteoporosis in old age. Look at the old people in every basketball game and you will know how strong the bones are.
