When shooting, the ball was thrown straight, but why did God come out to help when the basket collapsed twice?

Shooting action has the following technical links: holding the ball, aiming at the point under the basket, coordinating efforts, shooting angle and speed, ball rotation, shooting arc and shooting angle. In the competition, there are many factors that affect the shooting percentage, such as physical condition, shooting technique, shooting opportunity, psychological quality and so on. These all affect the shooting percentage to a certain extent. This paper mainly analyzes how to master the correct shooting technical action from the angle of the internal relationship between shooting technical action and shooting effect, so as to improve the accuracy of shooting. First, several phenomena in shooting with low hit rate. The shooting action with low hit rate generally has the following phenomena: 1, the aiming point is not well controlled, which makes the flying direction of the ball deviate from left to right; 2. When the ball flies in the air, it does not rotate backwards, but sideways; 3. Arc casting is either too high or too low; 4. The flying distance of the ball is not well controlled; 5. The concept of force sequence of shooting action is vague, which leads to blunt and uncoordinated shooting action. The reason for the above phenomenon is usually considered as the shooter's poor familiarity with the ball; Or the shooting time is not good and the shooting is hasty; Or poor physical condition and psychological quality. For different objects and occasions, the above analysis is not unreasonable. However, in most cases, it is more important that the shooter has a wrong understanding of how to correctly control the shooting and the order of shooting, and lacks a correct and specific understanding of the real cause of the wrong flight path caused by the thrown ball, so it is impossible to correct it effectively and flexibly in special circumstances, which is one of the important reasons for the low hit rate. To some extent, this also reflects the ambiguity and imperfection of the traditional teaching method of shooting skills in effective ball control. Second, the analysis of the internal relationship between shooting technical action and effect. In the teaching and training of basketball shooting skills, the relationship between fingers, wrists and arms and shooting effect can be reasonably used to guide the teaching and training of shooting actions; The teaching and training of shooting technical movements can be successful in a short time by using the control and adjustment of behavioral movements. This teaching method is suitable for basketball players at all levels and can get twice the result with half the effort for beginners. The following is an example of one-handed shooting in situ. 1, handle the relationship between fingers, wrists and shooting. When shooting, the five fingers of the ball holder are naturally separated, especially the index finger and middle finger are separated more, which is the last part before the ball is shot, which is very important. Touch the ball above the palm root to increase the contact area between the hand and the ball, and hold the ball with the other hand. The shooter's index finger and middle finger must face the hoop (not necessarily the elbow joint, otherwise the movement will be stiff), the projection point of the basketball center of gravity falls between the finger roots of the two fingers (index finger and middle finger), and the wrist leans back. When putting the ball, bend your wrist forward and pick it up with your fingers. Finally, throw the ball out gently and forcefully through food and middle finger. We should pay attention to three aspects and control and adjust the ball in a targeted manner. 1) Whether the thrown ball rotates backward around the transverse axis. 2) Whether the thrown ball has left-right deviation. 3) Protective gear is also an important factor that directly affects the shooting accuracy. 2. Handle the relationship between arm and shooting. Novices usually feel unable to control the parabola of the ball when shooting. Height is high or low, distance is far or near, which affects the accuracy of shooting. In shooting teaching, many teachers lack sufficient effective teaching methods and means for beginners to specifically adjust shooting movements. People used to divide shooting parabolas into three types: high, medium and low. Practice has proved that the medium parabola is the most ideal. The arc height depends on the shooting angle and speed, and the shooting distance and height are also closely related to the arc height. Specifically, it is achieved by acting on the hands and arms of the sphere, depending on the angle between the shooting arm and the horizontal plane and the moderate force of the fingers, wrists and arms. We can regard the parabola of the ball flight as a resultant force, which can be decomposed into two components, vertical upward and horizontal forward. It is controlled by the upper arm and forearm of the shooting arm respectively, which effectively solves the problem that parabola is difficult to control. When shooting, if the parabola of the thrown ball is too high, actively reduce the lifting range of the upper arm and reduce the angle between the arm and the horizontal plane; If the parabola of the thrown ball is too low, the lifting range of the upper arm should be increased and the angle between the arm and the horizontal plane should be increased; If the flying distance of the thrown ball is not enough, the range and speed of forearm extension should be increased; If the ball flies too far, the forward extension and speed of the forearm will be reduced. Generally speaking, the shooting angle of 6-7 meters long-distance shooting is 50-55, the shooting angle of 5 meters long-distance shooting is 70, the angle between the upper arm and the vertical line of the body is about 30, and the highest point of the arc is above the level of the hoop 1.2-2 meters. However, it should be noted that the shooting arc can not be a pattern because of the shooter's height, shooting mode (hollow, hitting the board), shooting distance, shooting speed and defensive interference. We should proceed from actual combat, be familiar with the general rules, be good at distinguishing situations and deal with them with cameras. For beginners, in practice, according to the different situations of the final shot and the teacher's prompt, we should make timely adjustments to ensure the accuracy of shooting action and shooting. 3. Re-recognize the force sequence of various parts of the body when shooting. According to the traditional teaching method, the force sequence of all parts of the body is from bottom to top when shooting. When shooting, push and stretch your lower limbs, stretch your waist and abdomen according to the situation, lift your elbow and extend your forearm, bend your wrist forward, pick the ball with your fingers, and finally throw the ball gently and forcefully through your index finger and middle finger. However, more and more experienced teachers believe that for beginners, it is necessary to re-understand the order of exertion of various parts of the body. The sequence of exertion should start with fingers and wrists, with forearms and upper arms as the main force, and then the coordination of waist, abdomen and lower limbs. Novices are not familiar with the ball, so they can't accurately control all parts of the body to act on the ball in turn when shooting. Fingers, wrists and arms (forearms and upper arms) play a leading role in the correct hitting of the ball. Clearly pointing out the dominant position of finger, wrist and arm in the shooting process can help beginners to concentrate more, complete the shooting action more pertinently and improve the shooting effect. Of course, in the case of poor arm strength or long shooting distance, the active cooperation of waist, abdomen and lower limbs is also very important, which has a very significant compensation efficiency for shooting height and distance. From this perspective, jump shot is a typical representative of this compensation efficiency. Therefore, when beginners learn to shoot, the teacher should point out that the order of exertion is from the fingers and wrists, the adjustment of arms and the active cooperation of waist, abdomen and lower limbs to complete the shooting action. We should pay attention to the consistency, coordination and rapidity of the whole shooting action, and we should not be out of touch with each other.
