The static aesthetic principle of the crotch dunk is similar, whether it is a two-foot jump crotch, a one-foot jump crotch, a crotch back buckle or a rotating crotch are all in the scope of discussion, as for what is the difficulty, height, integrity, and room for deduction, that is outside the static beauty,

It can be said that the two main points of the crotch dunk are the general triangle and the five lines in the details.

What is a triangle ... This is to describe a triangle surrounded by a three-point line of head and feet when changing hands under the crotch, such as the crotch change dunk when Carter received Maddy's pass...

What makes a triangle beautiful? First of all, the bottom line should be flat, that is, the height of the feet is similar, so that the triangle is relatively stable and comfortable to look at; Secondly, this triangle should be isosceles as much as possible, that is, the distance from the feet to the head should be as similar as possible, so that the triangle is more symmetrical and coordinated; Finally, try not to break this triangle with other parts of the body, otherwise the overall look will be irregular and abrupt.

Carter's triangle, flat bottom, isosceles, standard, three-point possession, looks very comfortable, and when George participated in the slam dunk contest, the bottom is uneven, the waist is not equal, and the specification is okay, but the posture of raising the right knee and hanging down the left foot makes it one of the most uneven and unequal triangles at the bottom, which is a deformity.

The uneven bottom and non-isosceles triangle George has shown it in the crotch change dunk for everyone, so what does the irregular triangle look like?

Lillard has a crotch dunk with a change of hands, which is a triangle with a flat bottom and a relatively equal waist, but the left knee breaks this triangle, which looks good overall, but if it can not be broken, it looks even better.

So is it that as long as the general posture maintains a flat bottom, isosceles, and a standardized triangle, it must be a very beautiful crotch? Not necessarily, because there is a second point, five lines... The second point is that this one is more detail-oriented than a triangle in general.

The five lines refer to the torso, thighs x2, and calves x2. These five lines are about the same length for a slender and beautiful person, of course, when it comes to the picture, it will be affected by the shooting angle, for example, the same front or back shot, the upper shot shows the length of the body, and the lower shot shows the length of the legs. If the three points of the head and feet are the framework for a crotch dunk, then these five lines are the internal details. The shape of these five lines and the angles between them will affect the beauty of a crotch dunk.

How these five lines are placed... First of all, the line of the torso should be as straight as possible, because 1. Straight drive looks stretched, and the hunched prawn style looks obscene, 2. Because there is no force point in the air, bending down and lowering the upper body will bring the effect of improving the position of the legs, which will reduce the necessary movement amplitude under the crotch, which is a bit of a shortcut, 3. The position of the hip crotch of the person is considered an axis, connecting three of the five lines, and the closer this axis is to the middle of the two waists of this isosceles triangle, that is, as much as possible on a perpendicular line with the head, the more coordinated it looks.

Then lift the knee of the leg of the thigh line, as far as possible parallel to the bottom of the triangle, one is to flatten it to look stable and coordinated, the other is that the knee is farthest from the torso, can be close to or reach the triangle waist position, jump to support the role of the triangle shape, this knee generally does not have to worry about breaking through the triangle, the vast majority of the knee breaking through the triangle is caused by the thigh and calf angle is too small, and the crotch change hand is changed under the thigh, if the angle is too small, the ball will be changed to the calf.

After these two lines are determined, the others are naturally determined, lift the knee of the leg, the line of the calf, and the thigh, and keep the angle between the leg and the thigh so that the foot can fall on the left and right position of the extension line of the head-knee line, so that the triangle is high enough (the calf is more vertical), stable (the knee is also supporting the frame), and standardized (the angle between the knee is not particularly small, and it will not break through the triangle). And because the axis of the crotch is in the middle position, and the length of the 4 lines on the left leg and the right leg is similar, then to maintain the isosceles triangle, the opening angle of the left and right leg knees must be about the same, and it is natural to pose the best crotch posture in theory.

However, this posture is unrealistic, because 1. The length of a person's arm exceeds the torso is limited, even if the arm is very long, the degree to which the wrist is lower than ** when the torso is straight is also limited, how to have an extra room for basketball? 2. Even if there is enough leeway, such as changing volleyballs, mineral water bottles, table tennis balls, etc., it should be possible to do it with the arms completely drooping, and the shoulders and crotch are coveted when the torso is upright.

Looking back and thinking about Carter's crotch change hands dunk back then, the state of the five lines is very close to the ideal picture, almost perfect!

Except for the slight forward leaning of the upper body, which is almost the same as the ideal picture, Carter's triangle, combined with five lines, has 5 points to support, which is extremely stable, in addition to the head and feet, the knees are also supporting the frame.

And Derrick Williams had a crotch change hand dunk back then, although the triangle was very positive, but the five lines inside were shrunk together, and the position angle was uncomfortable, which looked obscene.

Not to mention George! Not to mention that the triangle is not standardized, two of the five lines are about to merge into one, how beautiful!

The triangle and the five lines are all finished, in fact, there are some noteworthy places in the beauty of the crotch, but the content is less, I don't have a separate headline, that is, the position of the hand and the arm posture, the arm posture is naturally straight, and the trunk straight principle is the same, stretch, the distance is long, the action is full and does not copy the shortcut, and the position of the ball when changing hands, theoretically the closer to the middle position, the better, and the crotch position is the same as the principle of the center, that is, the closer to the **, the better!

How do Carter do these two aspects, you can find a picture to see, under the premise of the standard triangle and five lines, plus the standard straight arm change hands, the position of the ball is naturally near the **, it is the standard and beautiful "crotch change hands", if the person's torso bends forward obviously, and the arm bends forward, it becomes a knee change of hands, which is naturally one of the ways to take a shortcut, a person can be lifted under the thigh The highest position is near the knee, and the distance is the shortest.

Combined with the triangle, the five lines, and the arm posture of the hand-changing position, some legs fly everywhere under the crotch; bending over prawn crotch; Splitting and pulling the crotch, often the knee is going to reach the chin, which is very ugly, which affects the overall beauty!

This is also why a crotch change hands does different people have different feelings!
