The advantage of jump shot is that it is not as easy to be blocked by opponents as in-situ shooting. Young athletes may not be able to jump shot well because of the lack of muscle strength in legs, arms, shoulders and back, so they can give up temporarily, otherwise the wrong action caused by insufficient strength will affect their self-confidence, and it will be difficult to obtain the ideal jump shot technique after the strength meets the requirements. The technical essentials of jump shot are as follows:

Hold the ball with both hands and put the non-shooter in front of or on the side of the ball (according to your comfortable position). The shooter puts the ball behind his back, knees slightly bent, hands holding the ball from his chest to his eyes, and then his feet bounce. When jumping up, bend your elbow (forearm backwards) and turn your wrist backwards. When jumping to the highest point, reach forward with your forearm, throw the ball forward and down with your wrist, follow the ball with all your strength, and keep your eyes on the basket all the time.

2. How to improve the shooting percentage?

Basketball is a sport with strong technical comprehensiveness, and the number of shooting points determines the outcome of the game. Then, how to create more scoring opportunities and improve the shooting percentage, the following are some methods in teaching and training:

First, strengthen the practice of standardized shooting movements. Shooting has one hand and two hands, no matter which way is adopted, it must be done in strict accordance with standardized movements. Cultivating and mastering the sense of muscle when shooting is the premise of taking precedence over everything, so we should increase the practice of standardized shooting actions and finally achieve dynamic stereotypes.

Second, improve the level of physical training. The degree of physical training is the basis of completing all kinds of technical movements and has obvious influence on shooting percentage. For example, for players with poor physical training, the hit rate dropped significantly when the amount of exercise increased. Therefore, shooting should be combined with physical training, and shooting training should be carried out within a certain lower limit of intensity, so that there is enough physical strength to ensure the stability and improvement of shooting percentage in fierce competitions.

Third, choose a good shooting opportunity and make a decisive shot. Good shooting timing is the key to improve shooting percentage. Good scoring opportunities are created by the cooperation of individuals and the whole team, and we should be good at catching shooting opportunities. The shooter should observe the defender's center of gravity, position and defensive distance. Once the defensive side loses its normal defensive position and cannot interfere with shooting, or when the shooter induces the defensive side to lose its center of gravity, position and defensive distance with fake actions, the shooter creates a shooting opportunity and makes a decisive shot. Take advantage of the opportunities created by team tactics or take advantage of the temporary time difference and sense of space between the offensive and defensive sides.

Fourth, we must have a strong desire and confidence to shoot. Strong shooting desire and self-confidence are the premise of improving shooting percentage and play an important role in shooting. In teaching, it is necessary to make shooters fully exercise, master various shooting skills and give full play to their subjective initiative. Usually, we should pay more attention to students, help them, encourage them, praise them and cultivate their self-confidence.

Fifth, strengthen the training of overall coordination and stability of hand movements. In the game, it is often seen that some shooters can still throw the ball when they suddenly lose their balance under the action of external force, which shows that the shooter has good physical coordination, his body and hands are relatively stable at the moment of releasing the ball, and the shooter has a strong sense of time and space, good hand feeling and strong self-confidence, which makes the whole shooting action even, soft and natural, coherent and smooth.

Sixth, choose the right shooting angle and the flight path of the ball. According to science and practice, the shooting angle of the ball affects the flight path of the ball. Generally, there are three kinds of flight trajectories of the ball: low arc, middle arc and high arc, and the middle arc is the best. However, because the shooting distance is different, the player's height and bouncing quality are also different, so the flight trajectory of the ball is different when shooting, which should be decided according to the actual situation in training. At the same time, stable psychological factors are also very important. Learn self-adjustment and self-suggestion, and take reasonable and decisive action to shoot, which is not affected by the referee, the venue, the audience, the atmosphere and the score.

3。 Hand height

"The height of the shooting point varies from person to person."

The shooting position is closely related to everyone's action habits and the situation at that time. A player who is used to shooting with his shoulders at the head high or lower position basically has room for him to exist on the court, because no matter how his opponent knocks on the pot or covers his hat, you must never say that he can't shoot well! As the name implies, it is a little difficult for you to knock on his lid. Especially if this person is tall and flexible, he can basically turn a blind eye to others as soon as he holds the ball, unless he is in a highly competitive NBA arena!

From here, you can't say that parents in the East or families in the West are short! In particular, many people shoot after receiving the ball, rather than jumping up and standing up straight after receiving the ball. In other words, even if he jumps to the highest point, you must never say that he is wrong, otherwise it will be your fault. Even if catching the ball, jumping up and standing up will be ugly, you can't say that he is wrong. Because of this, the level of hand points can vary from person to person, as long as you get used to it. Don't be picky about what you have to do, which is not absolute among basketball coaches.

"Advantages and disadvantages of master points"

Of course, high shooting points also have high advantages, but they are unlikely to be fanned by people who are short or have poor bounce. When the shooting point is high, the shooting range, that is, the projection angle, can be relatively reduced, so it is not necessary to be so laborious, because the higher the projection angle, the more laborious it is; Of course, the shooting point height also includes the following advantages. For example, because his shooting action is completely completed, including pushing and stretching his forearm, pressing (bending) his wrist and snapping his fingers, then the strength of his toes can be completely connected to his fingers, which is what we generally call practicing chain action. Therefore, such arms, wrists and fingers,

This is the relationship. Therefore, when the shooting point is high, the arm is straight and follows through when shooting, the arm is not bent, and the body also has the feeling of jumping and throwing the ball with the head to the basket; I want to remind you in particular that the last shot is a flick of the finger. Like shot put in track and field and throwing in baseball, there is a finger pop-up action. Especially if you can see slow motion, you will find the index finger and middle finger at the end.

But it is also true that the higher your shooting point means the slower you shoot, just like what we commonly call "shooting with a straight pull rod", which is easily blocked by hot pot; If you are really slow, you must take it step by step. You must shoot less and pass more, just like Lao Xu!

"Advantages and disadvantages of low hand point"

Therefore, high and low beats have their own advantages and disadvantages. But for orientals with short stature, if the shooting point is not "early", that is, if they want to jump to the highest point and shoot again, they are easily blocked by hot pot; Therefore, of course, the lower the shooting point, the greater the shooting range, that is, the greater the projection angle, and the more effort it takes. Under the condition that the basket height is fixed at 3.05m, it is more difficult to catch the target, which is an obvious disadvantage.

There are several other issues that shooters need to think about. First, they should shoot low and early, such as patting the shoulders, which means that the strength of arms, wrists and fingers has not been fully exerted. At this time, most of the shooting power comes from the operation of feet and big arms, which shows that the "follow-up" in shooting essentials can not be fully exerted (the arm has not been fully exerted). Therefore, you will find that such shooting is incoherent.

Secondly, from the mechanical point of view, this blow must also be due to the lack of the unfavorable principle of supination because it does not use the downward pressure of the wrist and the bounce of the finger; Because, when shooting, if the ball can't rotate backwards and downwards, it will inevitably cause the ball to float left and right, which is the law of wasting energy in physics. The so-called principle that the air pressure is different after the ball passes (similar to the suspended kick-off in volleyball service), so that the ball will float up and down. So, is this kind of shooting without rotating back and forth good? In practice, of course, the disadvantages outweigh the advantages; On the one hand, the shooting trajectory will deviate, on the other hand, it is not easy to roll in when shooting fails (rotation will change the reflection angle), and on the other hand, it is difficult to control the shooting range when there is a headwind outside.

4。 Emergency stop jumper

There are two kinds of jumper: one is dribbling jumper, the other is walking empty-handed and catching jumper; The two movements are related, but completely different, especially if you dribble yourself to stop the jump shot, plus all kinds of dribbling, it is more difficult. In action practice, I always teach players to shoot in situ, jump up empty-handed, wait for him to jump up empty-handed, pass the ball to him again and again to catch the jumper, then train for quick dribbling, then practice the jumper with the ball, and finally practice the jumper with the ball, such as turning around or changing hands.

First of all, you need to have an idea that you can't shoot in situ, you can't learn to shoot in situ, and you can't learn to shoot in situ, so shooting in situ will be ridiculous, so you must learn it well first. Then you must understand that you must first learn to "stop running" empty-handed. You must have the skills to run, so you need the skills to stop running. Then, when you learn not to run, learn not to run or jump. Because you can stop running, you don't necessarily "jump immediately" after an emergency stop, so of course you should learn to stop jumping empty-handed.

When the learner learns to stop running and jump, he is invited to learn the fast transfer on the field, and another person passes the ball to him to catch the jump shot, so that the five actions of running, stopping, catching the ball, jumping and throwing can be completed "continuously". Then I will do my own quick dribbling and emergency stop training, and experience the feeling of dribbling and emergency stop. Then I will do dribbling and emergency stop, catch the ball, jump up and shoot, that is, practice dribbling and emergency stop jump shot. Finally, practice all kinds of difficult movements such as turning around, behind your back or changing hands.

In the technique of stopping jump shot, there are several actions that you must pay attention to:

First, you have to bend your feet to make an emergency stop; Many people don't bend their feet enough after running fast, so when they want to stop suddenly, they often can't stop or walk.

Second, stop is to press the heel to the ground first, and then press the forefoot to the ground to make an emergency stop. Finally, the feet are bent, and the calves, knees and thighs are forced to stop in turn. This part of the action diagram can refer to the following figure. Hold your heel, bend your foot, lower your center of gravity and stop the jump shot. Yes, it jumps fast and fast.

Third, the jump shot before dribbling and catching the ball should be pressed very low, which can remind you that your feet are bent, which will make you jump very fast.

Fourth, jump shot is to jump fast, jump fast, don't jump too high, and wait for others to come to the hot pot.

Fifth, the main strength of jump shot comes from running strength and bouncing strength, that is, the horizontal strength is changed into vertical strength, so the arm is gently pushed, the wrist is lightly pressed, and the finger is lightly flicked. Therefore, the action of stopping the jump shot is very light, and the "fulcrum" of each action is very stable.

Sixth, insufficient foot muscle endurance and unreasonable in-situ shooting are the two biggest factors that affect the hit rate of sudden stop jump shot; Lack of muscle endurance means that you can't stop, jump or jump fast; The action of in-situ shooting is unreasonable, and the point of shifting shooting is more difficult to grasp.

Seventh, it is best to stop jumping with one foot, and then step on the subsequent foot jump jumper; Of course, if your feet are strong enough, like many Korean players, you can of course make a jump shot with your feet stopped.

5。 disappear gradually

Finally, talk about the technical action of back jump shooting.

1, the backward jump is actually a backward jump, not a real vertical jump and then backward, just watch the video. But some of Joe's balls do take off vertically, which should be attributed to his amazing coordination. At the same time, pay attention to the stability of the back jump, lean back a little and then take off. If you lean back hard to avoid each other and jump again, the action will be ugly and become a laughing stock. The jump height is certain. If it is not high enough, it is a reverse shot.

2. After the take-off, the waist muscles exert their strength, and the body leans back, making full use of the strength and coordination of the waist and abdomen to pitch. Before throwing the ball, the abdominal muscles contract instantly. At this time, the forearm pitch needs a certain amount of power, and the radian should not be too high. Good wrist strength can be directly and completely achieved by wrist strength. Young friends often fail to shoot well because their fingers and wrists are not strong enough. In fact, shooting mainly depends on their wrists. It is recommended to practice your wrists and fingers before practicing jump shot.

The action before takeoff is also very important. Take right-handed shooting as an example:

1, the most common stop, pick up the ball, take a step or jump to stop, right foot in front.

2. Stop more suddenly. Slow down slightly when running, stop your left foot, put your left foot in front, and jump immediately when your left foot exerts its strength (sweating or landing, and the left foot is heavily loaded). This is McGrady's usual way of stopping and jumping back and forth. It is more difficult, because in the air, the body should turn left and turn to the basket, and the right leg often "kicks forward". Friends who often watch rocket games should be familiar with McGrady's shooting style. Kicking the right leg far can slow down the rotation speed, help stabilize the body shape and facilitate the hand. Such an abrupt end is often unexpected by opponents.

3. When your back is to the basket, squeeze your opponent and immediately use the back step to form a shooting opportunity. High center and power forward often shoot ordinary shots, while perimeter players need to throw back jump shots to use such actions.

4. Make a breakthrough or fake shooting to win the shooting space. There are many ways to do this, and it is often used in streetball.

6。 How to practice

First, take-off training

Take-off is divided into in-situ take-off, one-step emergency take-off and two-step emergency take-off. No matter what kind of take-off, it needs to be explosive, sudden and fast, and the ankle, knee and hip joints should be fully extended to drive the take-off with the swing arm. The exercise method is as follows:

1. Push and pull in situ

The practitioner stands in the same place, with his feet shoulder-width apart, crouching for half, and his arms naturally placed at his sides to do lift heel exercises. It is required to fully stretch the knees and hips and keep the upper body upright.

2. Hold the ball in place, push and extend the swing arm.

Leg movements, same as above. Holding the ball with both hands is located in the middle of the right side of the abdomen, holding the ball with the left hand under it, pressing the ball with the right hand on the floor, and sticking the right forearm on the right side of the waist. While kicking the ground, the left hand quickly lifts the ball, while the right hand keeps the ball stable and lifts it to the position where one hand slaps the shoulder. Naturally, the right hand lifts the ball, and both hands and the ball can't block the line of sight. When the right hand is required to hold the ball, the five fingers are naturally separated, the palm is empty, the ball is held above the root of the finger, and the thumb and little finger control the ball; Pay attention to stick the ball to the abdomen, stick the right arm to the waist and lift the ball from bottom to top.

Step 3 take off with the ball

On the basis of 2, it is required to jump and fly, and still hold the ball in an upright position of 2 in the air to maintain the stability of the ball and not to shoot.

4. One-step emergency stop and takeoff

On the basis of taking off in place, add one step to the left or right to stop taking off, and other movements are unchanged.

5. Two-step emergency stop takeoff

On the basis of completing one-step emergency stop take-off, step take-off is increased by moving left and right. The key point of action is (taking moving to the right as an example): while the left leg is moving to the right, the right foot actively, forcefully and quickly pushes off the ground and follows the left foot to land, so that both feet land almost at the same time. After landing, the requirements are the same as 4.

Second, in-situ shooting training

Generally, the training methods from easy to difficult are adopted, mainly including the following training methods:

1. Freehand imitation exercise

The upper and lower limbs are required to coordinate their efforts and the arms are fully extended.

2. Close-range shooting practice

On the basis of imitation exercise with bare hands, it is emphasized that the movement technique should be correct, the ball should be thrown by bending the wrist and picking with fingers, and the elbow must be pushed up.

3. medium and long distance shooting

In the case of increasing the distance, keep the whole body stable, with special emphasis on correct shooting techniques and hand shape after shooting.

Third, the training of jump shot

Jump shot is mainly to master the unity of take-off and shooting techniques. The difficulty lies in how to grasp the shooting opportunity. Generally, when the body is about to reach the highest point, its training methods are:

1. Help jump shot

The player holding the ball is ready to jump and shoot, and the other player holds the lower part of the player's waist with both hands from behind. When the athlete with the ball takes off, lift it with both hands. When the player with the ball jumps near the highest point, he will shoot again and let the player experience the opportunity of shooting in the air.

2. Close-range jumper practice

You can take off in the same place, or you can take off in one step or two steps. The purpose is to coordinate the take-off and keep the correct action and its stability in the air. It is required to push the ground with all one's strength and take off and lift the ball synchronously.

3. Mid-range jumper practice

In the case of increasing the distance, we should first do a good job in the action, especially the shooting technique and the hand shape after shooting, so as to finalize the action, and then adjust the shooting intensity, gradually improve the shooting technique and improve the shooting percentage.

4. Combine other techniques to practice jump shot

Combine single jump shot technology with transportation, transmission and sudden technology, and pay special attention to solving the connection problem between technologies, so that jump shot technology can be skillfully combined with other technologies. For example, when dribbling for an emergency jump shot, you should pay attention to facing the basket when taking off or stepping to catch the ball, the emergency stop and take-off should be well connected, and the landing should be fast and powerful; The first step is to overcome the forward momentum and take off quickly and forcefully.

5. Practice jump shots in competitions and confrontations.

First of all, practice consolidating the action stereotype of jump shot in the case of passive defense, and then practice gradually against the game.
