2. First of all, it is based on the first point. As we all know, the subtle technique is here. When the five fingers are forcibly separated, the index finger and the middle finger are relatively closed, that is to say, the thumb and the ring finger are forcibly separated, and the index finger and the middle finger are only in a state of natural separation, and the two fingers are almost parallel.
So far, these two points, especially the second point, are very important, so I won't say more about the reasons. Different people have different opinions, and people who like to think will know this truth. This little trick just combines the advantages of being soft and hard.
First of all, you may wonder why your thumb, forefinger and middle finger are too stiff to pick up the ball.
In fact, the fundamental question of which finger to use to pick the ball is that the center of gravity of the ball falls on your hand when holding the ball. For example, when you hold the ball, the center of gravity of the ball is in the middle finger. If you pluck the ball with your index finger, it must be one-sided, because your strength does not pass through the center of the ball. If you push the shot put, you will know that the shot put has made this problem very big.
Then why are these three fingers picking up the ball?
Everyone should have had this experience when they first started practicing straight-line shooting (forearm is perpendicular to the ground), that is, their wrists can't turn around, but in order to ensure that their forearms are perpendicular to the ground, they can only use their forefinger or thumb to pick up the ball, and their palms can't face the basket. Just practice for a while. This is because the forearm has two bones, ulna and radius, which cannot be completely bypassed. Not much to say here. There is such an explanation on the Internet. When you can almost turn your wrist now, will you consider whether to pick the ball with your thumb, index finger and middle finger or ring finger?
When I was an intern here, this problem bothered me for a long time. If it is the first type, it can ensure the straight line force. If it is the second type, the forearm may be slightly inclined, but the fingering will be much smoother. I don't know if you have this experience. But I'm here to tell you that it can only be the first way to pick the ball. Why?
The first reason is that your forearm must be perpendicular to the ground, but this is only a superficial reason. The second reason is that the two bones of our forearm, the ulna and the radius, are clearly defined. The ulna is the main one, and the radius is only the auxiliary one. Because the ulna is longer than the radius, no matter how thick your arms and wrists are, it is your ulna that transmits the strength of your arms to the palm of your hand. The width of the joint between ulna and wrist is from the index finger to the middle finger, which means that the direction of forearm force is just at the index finger and middle finger, and the ring finger is the radius, which does not participate in the force, or the center of gravity is not there, so if you want to hit the ball directly, but stir the ball in the second way, there will always be a gap between the direction of your forearm force and the center of gravity of the ball, which means that if you want to hit it directly, your forearm will be inclined. Unfortunately, we can't draw, so we have to give full play to our imagination.
Moreover, Jordan also said in the video of teaching free throws that if you use these three fingers, the ball with the ring finger will go astray, which is true, but Jordan's style is unreasonable. By the way, I replied to a netizen that the difference between free throws and shooting is only in borrowing power, and it is impossible to change it in picking up the ball. The reason for simplifying complexity is that the closer your jump shot is to the free throw, the higher your hit rate will be. No one can make a jump shot higher than the free throw. Let's just say he went into a misunderstanding.
When I decided to pluck the ball with my thumb, forefinger and middle finger, I also thought about the benefits of the second plucking, because the second plucking was really more comfortable in the early days. I don't know that one day I suddenly realized a neutralization method, that is, all four fingers participated. At that time, the five fingers were completely separated When holding the ball, tighten the ball with the thumb and ring finger as two fulcrums to make the center of gravity of the ball natural.
In other words, when you hold the ball, your thumb and ring finger are holding the ball on purpose. With a little effort, at least you should have this initiative in your mind. The forefinger and middle finger are relaxed. At the moment of picking up the ball, the thumb, index finger and middle finger are stiff, but the ring finger is not, so you will find that the finger type behind your hand is orchid finger. Jordan's blue finger also proves that Jordan's ring finger is there when picking up the ball.
In addition, a friend said that since the center of gravity of the ball is between the index finger and the middle finger, it is ok to pick the ball with the index finger and the middle finger. Why do you want to add a thumb? Will this make the strokes unbalanced?
If you have tried to pluck the ball with your thumb, if you study it with your head, you will find that the principle of plucking the ball with your thumb is completely different from that of plucking the ball with your forefinger and middle finger.
First: the forefinger and middle finger are rolling friction, that is to say, if you look at it in slow motion, the ball goes out from the root of the forefinger and middle finger to the fingertip, and the thumb is closer. When touching the ball, it is a feeling of catching it quickly.
Second, the stroke of the forefinger and middle finger gives the ball a forward force (almost all the forward force of the ball based on the vertical take-off principle comes from the stroke), while the stroke of the thumb scrapes the ball off, and the direction of wiping force is almost tangent to the bottom of the ball, giving the ball a backward swing force. After the thumb hits the ball, the fingertips are almost perpendicular to the ground. In other words, their division of labor is completely different. The forefinger and middle finger give the ball a forward force, which makes the ball rotate by the way, while the thumb only makes the ball rotate. You can hold the ball in your hand, just try it with your thumb, and you will find that the ball only rotates without moving forward, so the strength of your thumb will not affect the deviation of the center of gravity when you release the ball.
Third, thumb matting has another advantage. We know that if the forearm is perpendicular to the ground, the wrist should be deliberately rotated outward, right? If you don't use force, your wrist will automatically rotate a little, which means that the front of your palm may be biased to the left of the basket. If the ball is thrown, it may cause the ball to deviate from the left side of the basket, which can be prevented by thumb fingering. The thumb picks up the ball vertically downward (sometimes it can be slightly buckled according to your own situation), and its picking trajectory forms a section perpendicular to the ground, which is exactly the same as the section formed by your forearm when shooting straight, which can effectively prevent the ball from deviating from the left side of the basket when shooting, and even become your aiming tool.
Let's talk about the last point, the tips of properly folding the index finger and middle finger when holding the ball in the right hand. The convergence mentioned here is not complete convergence, because the ring finger is relatively closed after complete convergence, and more balls cannot be caught, which will affect the stability of holding the ball. Moreover, after complete convergence, the index finger and the middle finger were originally two points, but there was only one point, and the center of gravity of the ball was not stable enough.
This convergence means that the index finger and the middle finger can keep parallel as far as possible without affecting the stability of holding the ball, and the friend with the bigger hand has an advantage. The index finger and middle finger are parallel, so it's no problem that it doesn't affect the stability of holding the ball like Jordan, so it's difficult for me to do it. I used to play football, and my height was average, and my hands were definitely not much bigger, but I can tell you a practice method, that is, in guitar teaching, I use my left wrist or forearm when I have time.
Why should the index finger and middle finger be slightly close together?
I think many friends may have discovered this problem long ago, or they may just know it quietly, so it is not convenient to share it. Maybe they know about it, but they don't know why. It's like a friend leaving a message saying that it's easier to tie two fingers together, but I don't know if it's psychological. I can tell you for sure that it will be easier to shoot, which is based on mechanical theory. You will understand after reading it. I said this little trick just combines hard hands and hard hands. Let me first analyze the characteristics, advantages and disadvantages of hard hands and soft hands.
The characteristic of hard hand is that the five fingers are deliberately separated to catch the ball, the palm is empty, and there are usually fixed fingers to pick up the ball. The advantage is that holding the ball will be very stable, which is very suitable for jump shots under physical confrontation. The disadvantage is that it will be more difficult to pick up the ball with your fingers. The most obvious thing is that when you hit the basket with hard hands, because you are close to the basket, you don't need any strength to pick up the ball, but the physical confrontation under the basket is fierce and you need to hold the ball very stably, so this is the hardest time for your hands. In this case, your shooting fingers hardly pick up the ball, just use the strength of your arms. Soft hands are characterized in that the five fingers naturally hold the ball separately, and the palms are basically not empty. General five-finger balance ball. The advantage is that it is easy to pick up the ball, but the disadvantage is that it is not stable enough to hold the ball under physical confrontation. It seems that you can't have it both ways, but if you know the essential difference, you can have it both ways.
When it comes to the difference between hard hands and soft hands, most people will think of whether they are empty-handed, and through my personal research, I find that whether they are empty-handed is just a representation, or just a phenomenon that distinguishes hard hands from soft hands. In my last article, I said that the ulna transmits the forearm strength in the wrist area. We can also imagine that the forearm strength is only transmitted at the root of the palm, not in the palm, whether it is hard or soft. The palm of your hand will not be empty, that is to say, being empty has little effect on your strength. You can do an experiment, that is, you hold the ball with soft hands, but the ball is just picked up on your fingers, and your strength is as full as it, and you will only feel a little awkward (because you have never thrown the ball like this).
What is the essential difference between hard hands and soft hands?
The answer lies in the angle between the finger and the ball. Let's start with a backhand, the forearm is perpendicular to the ground, and with the trajectory of the ball, we can imagine a tangent plane perpendicular to the ground, which I mentioned when I plucked the ball with my thumb. According to the principle of mechanics, if the force that your finger pushes the ball to the ball is on this tangent plane (at least parallel to this tangent plane), then it will be an effective force and the driving force for the ball to move forward. Let's look at the soft hand who picks the ball first. Fingers are close together, almost parallel to this tangent plane. The trajectory of finger picking up the ball is consistent with this tangent plane, so this force is basically an effective force. Where's the hard hand The forefinger and middle finger are placed upside down on the ball, and the trajectory of the finger picking the ball is not on this section. The force given to the ball is only the amount of your finger picking the ball on this section, and the rest is useless. The index finger and middle finger can be relatively close together to increase this weight. The closer they are, the greater their weight (the largest when they are parallel), but the more unstable they will hold the ball. So this assurance can be adjusted according to your own situation. So the advantage of big hands is that they can accept as much as possible.
At this point, even if Jordan's right-hand stroke technique is finished, friends who have the same experience may gain something.
Here, it is recommended to be a student basketball fan. Any technical action has advantages and disadvantages. You need to use your brain to study its fundamental principle (everything is the same) in order to become your own and give full play to the advantages of this technology in yourself. Otherwise, its advantages will become your disadvantages.
