Basketball knowledge three: basic basketball skills
1) Ball control skills
1. Hold the ball
Use five fingers Hold the ball and squeeze your fingers inwards. Catch the ball with the palm of your hand as it falls.
2. Trunk dribbling
Place the ball around your waist and circle it. The key to this action is to face forward and don’t look at the ball. Then do it clockwise and counterclockwise. Dribbling practice with clock.
3. Neck dribbling
Practice the ball around the neck. This exercise also faces forward. Do not move the neck, and do it in forward and counterclockwise directions. alternating exercises.
4. One-foot dribbling
With your feet separated and your center of gravity lowered, hold the ball on one foot and do dribbling exercises. Don't look at the ball, and use your left and right feet to do alternating exercises in forward and counterclockwise directions.
5. Throw the ball forward and backward while stepping down
Separate your feet and lower your center of gravity. Throw the ball lightly from the front to the back, quickly catch the ball from the back with both hands, and lightly throw the ball back to the front. Repeat this timekeeping exercise and try to see how many times you can complete it in thirty seconds.
6. Knee dribbling
With your feet slightly closer together and lowering your body's center of gravity, do dribbling exercises with the ball along your knees. Don't look at the ball, and practice alternately in forward and counterclockwise directions.
7. Self-driving dribbling under the 8-step
This is the application of one-legged dribbling. Move the ball along both feet to make a figure-8 dribbling, while keeping your eyes open. Look at the ball and practice alternating forward and counterclockwise directions.
Basketball Basketball Basketball Basketball Basketball Basketball Basketball was invented and created in 1891 by Mr. James Naismith of Springfield University in the United States. The earliest basketball competition rules were also formulated by Mr. Naismith.
His purpose in formulating basketball rules at that time was:
① Basketball is a sport played with hands, and the ball is round;
② Hold the ball in your hands Walking or running is not allowed;
③Athletes can go anywhere on the field as long as they do not affect or hinder the other players;
④Physical contact between athletes is not allowed ;
⑤The hoop should be horizontal.
Based on these 5 basic principles, Mr. Naismith formulated the most original basketball competition rules. The most original basketball competition rules have 13 rules. The basic contents of these 13 articles are:
1. Players can throw the ball in any direction with one or both hands.
2. Players can grab and hit the ball in any direction with one or both hands, but they must not hit the ball with their fists.
3. Players cannot take the ball away.
4. The ball must be held in hand, and kicking with the head or feet is not allowed.
5. Players are not allowed to use shoulder collision, hand pulling, hand pushing, hand hitting, foot tripping, etc. to deal with the other team's players. Any player who violates this rule will be deemed to have committed a foul for the first time. If he commits a second foul, he will be forced to stop playing and will not be able to re-enter the game until he hits a ball.
If an opponent's player is intentionally injured, he will be disqualified from the entire game and no substitutes will be allowed.
6. Boxing the ball is a violation of Rules 3 and 4.
7. If either side commits three consecutive fouls, the opponent will count as a hit. Continuous fouls mean that within a period of time, the opponent's players have not committed any fouls, but their own players have committed consecutive fouls.
8. If the defender does not touch the ball or interfere with the ball, it will be considered a basket when the ball is put into the basket and stays in the basket. If the ball stops on the basket and an opposing player touches the basket, it counts as a hit.
9. When the ball goes out of bounds, the ball will be thrown into the court by the first person who touches the ball. If there is a dispute, the referee throws the ball into the field. Five seconds are allowed for a throw-in. If it exceeds five seconds, the ball is awarded to the opponent.
10. The referee is the player’s referee and he has the right to call a foul. When a team commits three consecutive fouls, he will notify the assistant referee. He has the right to disqualify a player from the game.
11. The assistant referee is the referee of the ball. He can decide when the ball is in play, time the ball, determine the hit of the ball, record the number of hits, and bear the responsibilities that a referee should usually bear. .
12. The game is played in two 15-minute periods, with a 5-minute break in between.
13. The side with the most hits wins. If there is a tie, with the consent of the captains of both teams, the game can be postponed until another goal is hit.
Although these original 13 basketball competition rules are not systematic and complete, and some provisions are not clear enough, they played a great role in promoting the development of early basketball.
In particular, as basketball has developed into a modern basketball sport today, the technical and tactical levels are getting higher and higher, and the rules have become more important. They require strict, scientific and systematic management of basketball competitions.
Basketball Knowledge 4: The Evolution of Basketball Competition Rules
The modification of the rules has promoted the development of basketball, and the continuous improvement of basketball skills and tactics has promoted the inconsistency of the rules. Appropriate modifications or additions should be made to improve the local area, so as to make basketball develop in a healthy and advanced direction.
Rules, basketball skills and tactics are just like productivity and production relations. They are complementary, interdependent and mutually reinforcing. Rules ensure the normal conduct of basketball games and promote the healthy development of basketball through affirmation, denial, permission or disallowance. Actions on the court that comply with the rules are correct actions, otherwise they are wrong actions.
The rules have developed from the original 13 to the current 58, and the basketball skills and tactics have developed from the original simple and low-level to the current advanced level. This is the result of their mutual restriction and mutual promotion over many years. For example: dribbling technology has developed from initially using the elbow joint as the axis to now using the shoulder joint as the axis, precisely because the rules continue to affirm the developing technology. Now, the rules clearly state that the sign of the end of dribbling is the moment when both hands touch the ball or the palm of the dribbling hand is upward and the thumb exceeds the vertical plane. If the palm is always pointed downward and the thumb does not exceed the vertical plane, it is impossible for the ball to stay on the hand. Therefore, the modern technology of big-arm dribbling with the shoulder joint as the axis and one-hand pull-back and back-turn dribbling have been confirmed in legal form. Another example: the development of shooting technology, from the initial shooting with two hands on the chest, to the current master's top-down dunks and one-handed or two-handed tip-ins and other superb skills. The rules clearly stipulate that all players are doing it. Shooting action. Therefore, modern technologies such as dunks and tip-ins have developed rapidly. In recent years, various forms of techniques such as fadeaway jumpers, step-back jumpers, and hook jumpers have appeared in the game. This is also because the rules emphasize the principle of vertical plane, the principle of vacating players, etc. for offensive and defensive techniques to deal with physical contact and fouls. determined by the basic principles. In terms of foul handling, special emphasis is placed on the guiding ideology of offensive and defensive balance, forcing and promoting shooting players to adopt various forms of jump shooting techniques in order to get rid of the defense and avoid collision fouls, in order to achieve the purpose of scoring, and promote the continuous improvement of defensive tactics. development etc.
Under normal circumstances, FIBA ??will revise and supplement the rules every four years. The purpose is to promote the further development of basketball skills and tactics, and to limit rough movements and make the game more civilized. , Yu Jing and develop in an intense and energetic direction.
The changes in the rules are unknowable, and they are not changed at will by anyone on a whim. They are carried out according to a certain purpose of modification. The specific guiding principles for modifying the rules are:
1. Fairness. This is the basis for changing the rules. The rules should be fair to both sides of the game. Because a basketball game is a competition between two sides in basketball consciousness, skills, tactics and physical fitness under the same conditions of time, space, ground and number of people.
2. Balance. Balance (or balance) means that the two aspects of offense and defense must be balanced. If a game is easy to score or difficult to score, it will make the game dull and not exciting, and the exciting charm of the basketball game will be lost.
3. Definition. Rule definitions should be concise and clear, with precise text.
4. Compilation. Rules should be codified to avoid duplication, be consistent and not contradictory.
5. Short. Rules should be brief and concise to avoid being confusing and difficult for people to understand.
6. Exceptions. There are many provisions on the front of the rules. Without exceptions (i.e. annotations), the rules would be difficult to implement. The exceptions are just to ensure the implementation of the front rules.
7. Safety. The rules must ensure personal safety and ensure that the game proceeds smoothly in a good environment and atmosphere.
8. Power. Referees must be given the power to do their jobs and enforce the rules with authority during the game.
9. Continuous. The rules should minimize the number of interruptions in the game, thereby ensuring the continuity of the game and making the game more compact and exciting.
10. No benefit. The rules should ensure that neither party in the game can benefit from violating the rules, so that the game can be conducted fairly and reasonably.

(27) Passing: When an offensive player is covering, the player guarding the screener moves slightly away from the opponent, allowing his partner to pass between his screeners and continue to guard the opponent.
Basketball Knowledge 6: Shooting Precautions
There are many different shooting methods in basketball training and games, but no matter which shooting method, there are two things that must be done. :
First: exert force from the soles of the feet, which means that although you shoot with your hands, the force originates from the forefoot, and then passes through the ankles, knees, hips, upper body, arms, and wrists. Finally, the force is transferred to the fingertips to throw the basketball. The entire transfer of power should be a coherent and coordinated process.
Second: The arm posture should be such that the upper arm and forearm are at 90 degrees, and the wrist extension is also at nearly 90 degrees with the forearm and parallel to the upper arm. Hold the back and lower part of the ball with your fingers. When shooting, stretch your arms upwards and forwards (pointing to the basket of course), bend your wrists upwards and forwards, and finally push the ball out with your fingers. This way the basketball will produce backspin when shooting, and will not produce backspin when it hits the backboard or basket. Big backlash. You should also keep your hands in contact with the basketball as long as possible (that is, follow the ball for a long time). This will help control the direction of the ball and increase the shooting rate. Don't think too much about whether the ball went into the basket at the beginning. Focus on body posture, movement, and the rhythm of the entire shooting motion. You have to repeat the same action essentials every time you shoot. When the correct shooting action becomes smooth, your shooting rate will naturally increase. You should also practice shooting at different positions and angles from the basket.
Basketball Knowledge 7: One-handed shooting in place
One-handed shooting in place, especially for teenagers, is a basic shooting method. Let's take shooting with the right hand as an example:
Hold the ball with both hands at eye level, slightly to the right, with the right foot slightly forward than the left foot, bend the knees slightly, and lift the ball up , extend your right wrist back so that most of the weight of the ball falls on your right hand, gently hold the ball with your left hand from the left, exert force on the forefoot, lift your heels, straighten your knees, and extend your right arm to throw the ball (refer to About Shooting ) The shooting starts with the wrist bent back, then up and forward, with the fingertips being the last part to leave the ball.
Basketball knowledge eight: How to improve shooting percentage
Basketball is a technically comprehensive sport. The number of shots scored determines the outcome of the game. So, how to create more scoring opportunities and improve shooting accuracy, here are some methods in teaching and training:
1. Strengthen the practice of standardized shooting movements. There are one-handed and two-handed shooting movements. No matter which method is used, it must be done strictly according to the standardized movements. Cultivating and mastering the muscle feeling when shooting is a prerequisite that takes precedence over everything else. This requires increasing the practice of standardized shooting movements to ultimately achieve dynamic shaping.
2. Improve the level of physical training. The degree of physical training is the basis for completing various technical movements and has a significant impact on shooting percentage. For example, for players with poor physical training, when the amount of exercise increases, their hit rate will drop significantly. Therefore, shooting should be combined with physical training, and shooting training should be carried out under a certain intensity and within a limited time limit, so that in intense and intense games, there is enough physical strength to ensure the stability and improvement of the shooting percentage.
3. Choose a good shooting moment and take decisive action. Good shooting timing is the key to improving shooting percentage. A good scoring opportunity is created by the cooperation of individuals and the whole team. You must be good at capturing shooting opportunities. The shooter must observe the defensive player's center of gravity, position, and defensive distance. Once the defender loses his normal defensive position and cannot interfere with the shooting, or the shooter uses a fake move to induce the defender to lose his center of gravity, position, and defensive distance, the shooter Created shooting opportunities and took decisive shots. Take advantage of the opportunities created by the team's tactics or take advantage of the temporary time difference and space difference between the offense and defense to shoot immediately.
Fourth, you must have a strong desire to shoot and self-confidence. Strong desire to shoot and self-confidence are the prerequisites for improving shooting percentage and play an important role in shooting. In teaching, shooters should be able to fully exercise, master various shooting skills, and give full play to their subjective initiative. In normal times, students should be more concerned and helped, encouraged and praised more, so as to cultivate the self-confidence of shooters.
5. Training to strengthen whole-body coordination and stability of shooting movements. In competitions, it is often seen that some shooters can still shoot the ball when they are suddenly affected by an external force and lose their balance. This shows that the shooter has good physical coordination. At the moment when the ball is released, the body and hands are relatively stable. The shooter has a strong sense of time and space, good hand feel, and strong self-confidence, which makes the entire shooting movement even and soft, and the movements natural, coherent, and smooth.
6. Choose the appropriate shooting angle and ball flight path. According to science and practice, the ball's release angle affects the ball's flight path. The ball's flight path generally has three types: low arc, medium arc and high arc. Generally, the mid-arc is the best. However, due to the distance of the shooting distance, the height and jumping quality of the players, the flight path of the ball will be different when shooting, and it should be determined according to the actual situation during training. At the same time, stable psychological factors are also crucial. Learn to self-regulate and self-psychological suggestion. Don't be affected by the referee, venue, audience, atmosphere and score, and take reasonable and decisive actions to shoot.
Basketball knowledge nine: How to shoot a jump shot
The advantage of a jump shot is that it is not as easy to be blocked by the opponent as a shot in place. Young athletes may not be able to do jump shots due to insufficient strength in their legs, arms, shoulders and back muscles. They can give up temporarily. Otherwise, wrong movements caused by insufficient strength will affect their self-confidence and make it difficult for them to achieve the required strength in the future. Get the ideal jump shot technique. The technical essentials of a jump shot are as follows:
Hold the ball with both hands, and place the non-shooting hand in front or to the side of the ball (according to your comfortable position). Place your shooting hand behind the ball, bend your knees slightly, hold the ball from your chest to above your eyes with both hands, and then bounce your feet upward. When jumping, bend your elbows (forearms back) and turn your wrists back. When jumping to the highest point, extend your forearm forward, throw the ball forward and downward with your wrist, follow the ball (refer to About Shooting) fully, and keep your eyes on the basket.
Basketball knowledge ten: Three-step layup practice
Three-step layup is the most basic and simplest shooting technique. The following takes a three-step layup with the right hand as an example to illustrate how to practice:
Starting from about 3 or 4 meters away from the basket and slightly to the right, use your right hand to dribble forward toward the basket with one hand. , take the last step with your left foot (and prepare to take off). When taking the last step, hold the ball with both hands (left hand in front of the ball, right hand behind the ball and close to the bottom of the ball), use your left foot to take off, and keep your eyes on the basket. Near the direction you want to send the ball, leave the ball with your left hand, hold the ball with your right arm in one hand and fully extend it upwards. When it bounces to the highest point, use your wrist to send the ball (called a basket pick).
For a left-handed layup, you only need to dribble with your left hand, jump with your right foot, and pick the basket with your left hand. When you first start practicing, use your dominant hand (stronger hand) to lay up, and then practice using your other hand to lay up when you are familiar with the movement. If you find it difficult to master the take-off point or adjust the last step while dribbling, you can first practice stepping up, taking off, and shooting on the spot, and then start dribbling after you become proficient.
Basketball Knowledge 11: Basketball Injuries
Playing basketball is prone to "bone and joint" injuries. That is to say, young people whose bones have not yet hardened are most likely to develop knee joint edema when their knees are strongly stimulated. Prevention method: do some exercises that strongly stimulate the knees, such as full knee flexion exercises, bunny hops, etc. Don’t overdo it, and at the same time, train to strengthen the movements around the knee joint.
1) Ankle sprain
Wrapping the ankle with tape (bandage, bandage) before practice can help prevent sprains. However, the most effective method is still to do ankle preparation exercises and kick the ball on the side of one foot, which can also strengthen the muscles that should not be used. If you suffer a sprain, apply a cold compress to the affected area first and then apply appropriate pressure. When applying cold compresses, only use ice water. When applying pressure, first use a sponge and wrap it with an elastic bandage from above the sponge.
2) Finger poke
Caused by strong impact on the finger. Prevention method: Fully prepare your fingers for movement. Finger injuries can be divided into five types according to the degree: 1. Sprain, 2. Dislocation, 3. Fracture, 4. Tendon rupture, 5. Contusion (skin split). If a sprain occurs, the treatment method is the same as for sprains in other parts. Apply cold compress first, and after 2 to 3 days, keep the area warm and massage at the same time. When dislocating, you should be able to tolerate the pain, let the medical staff straighten the finger, restore it to its original shape, and then handle it in the same way as before. As for serious injuries, fractures, and tendon ruptures on the fingers, it is best not to move them around. It is best to seek medical treatment quickly.
3) Muscle dislocation
Applying sudden force (flexion or extension) to the muscle causes the muscle fibers in the muscle or part of the muscle membrane to rupture, and Cause internal bleeding. Prevention method: Before practicing, rub the muscles in various parts to relax them. Players with hard muscles should pay special attention during the hot and cold seasons. The treatment method is as follows: If it occurs in the legs, first immobilize the knee for 2 to 3 days without moving it at will, and apply water or ice ice at the same time. Wearing a bandage can prevent internal bleeding from expanding. After doing so, keep it warm for a while while engaging in light activities. The characteristic of this treatment is that after the internal bleeding stops, although the body still feels stiff, it is necessary to move a little.
4) Swelling and pain in the feet
When moving the feet, especially when practicing jerking and stopping movements for a long time, you will feel pain in the heel. This disease is also called heel bone disease. This is because when the foot is looking at the ground, the fatty tissue between the heel bone and the skin is damaged by multiple sharp impacts. The prevention method: place a soft sponge under the heel, or put cotton on the inside of the heel. This can prevent the subcutaneous tissue from being compressed to the side despite the force from below. The method of treating heel pain is not easy to operate. Before the pain disappears, try to avoid strong impact on the heel and practice ball at the same time.
Afterwards, you need to do treatment, such as applying hot compresses with warm and wet towels. Therefore, if this problem is ignored, it often becomes a chronic disease that is difficult to treat. It is best to deal with it in the early stages of the disease.
5) Knee injuries
Knees are prone to injuries when they are hit hard. Prevention method: Use knee pads. If you suffer a strong blow or bruise, the treatment method will depend on the situation. In severe cases, surgery may be necessary.
6) Foot injuries caused by the friction of sneakers
As long as you wear clean and wrinkle-free socks and suitable sneakers, you should be able to heal to some extent. preventive effect. If the blisters are caused by the friction of sneakers, do not burst the blisters hastily. It is best to disinfect the area first, then use a sterilized needle to squeeze out the covering fluid, and then attach the OK trip.
7) Corns
Corns are the keratinized and value-added parts of the skin. If the pistil is deep enough to reach the inside of the dermis, use a razor to carefully peel off the value-added part bit by bit.
Prevention method: When bathing, use a pumice stone to fully rub the thickened part of the skin
