First of all,
I. The position of the crotch
. The pelvis (also known as the pelvis and disc) is composed of the sacrum (a component of the spine, which is connected to the lumbar spine and the coccyx), the coccyx and two hip bones. The hip bone is in turn composed of the ilium, ischium, and pubic bone. Become.
There is a strong ligament to support the connection between the pubic bones, and it is generally unable to move. The connection between the ilium and the sacrum is also very tight, with almost no room for movement, so the pelvis is usually regarded as a whole.
The pelvic structure is shown in the figure below.
Viewed from the front, the pelvis is generally a trapezoid with a wide top and a narrow bottom. Viewed from the side, the pelvis is slightly tilted forward. The inclination of the female pelvis is greater than that of the male. The pubic area is probably at the position where the two hip tips are connected in front of the sacrum.
The recessed part of the acetabulum on both sides of the pelvis connects the femoral head of the thigh bone. The acetabulum is like an axial bowl. The front part of the femoral head is semicircular and embedded in this axial bowl. The femoral head and the acetabulum are also connected by strong ligaments and tendons.
The outer side of the femoral head is usually the widest part of the hip. The joint of the femur and the hip forms the hip belt. From the front of the human body, it is the place where the groin is located, which is what we call the crotch. The joint of the pubic bone is what we call the crotch, so there is only one crotch and the crotch. There are two left and right. Sometimes in the books of predecessors, you can see the saying about left crotch and right crotch, and I think it should be understood as left crotch and right crotch.
is different from the sacroiliac joint in that the hip joint (crotch) has a larger range of motion.
Our thighs can usually be lifted forward more than 90 degrees. With better ligaments, it can easily stick the thigh to the chest, over 135 degrees.
In a lunge, the angle between the back leg and the vertical line of the body is not difficult to exceed 45 degrees, so that the range of movement of the hip joints is about 180 degrees. But the range of left and right motion of the hip joint is much smaller than the range of front and back motion.
Whether it is in the same dimension as the upper body (standing upright and splitting the legs) or not in the same dimension (horizontal stepping left and right legs or sitting on the floor and splitting legs), generally no more than 90 degrees. This is not difficult to understand. We usually move forward, and few people walk or run sideways.
2. What is crotch opening
The range of motion of the crotch is larger for young children than adults, because young children have soft limbs and are full of blood. However, people in modern cities sit more often and do not move much. As they age, they suffer from qi stagnation and blood stasis to varying degrees, especially in joints. Therefore, the hip joints of adults are "corroded", and the older they are, the more severe the corrosion. But even young people, without training, the crotch is still in an "unopened" state.
People who have not opened their hips stand upright, the angle between their legs is difficult to open more than 90 degrees, and when the frame is lowered, the upper body will lean forward and push up the buttocks. When standing sideways, there will be a hard break in the front hip joint, where the strength of the upper and lower body is broken, and a little force is applied to this break, and the person falls backward.
So, how is the crotch open? Strong3strong opens the crotch to increase the amplitude of the hip joint upward movement and reduce the angle of this hard fold. For those with open hips, this hard bend almost completely disappeared when the second step of turning the waist in the forehand circle, the inner thigh and the lower abdomen were almost in the same plane, at least the crotch bend became rounded.
3. The role of hip opening
As I mentioned in the previous article, the power of Taijiquan is mainly structural power. The most important source of this structural force is the rebound force from the earth.Therefore, the movements of Taijiquan must be able to adjust its own structure to connect with the earth. To do this, it is extremely important that the hips are not opened.
The crotch does not open, the strength is disconnected here, the strength on the feet does not come up, it cannot be transmitted to the hands, the strength on the body does not go down, and it cannot be transmitted to the feet. Can't send out.
Not only is the strength disconnected at the hips, but also at the knees. The strength is held in the knees, causing knee pain. Moreover, the knees cannot be motionless without opening the hips, and they are forced to stop. It is more stressed and often hurts more.
is not only because the knees cannot be truly immobile, but the hips cannot move other parts of the body (including the central axis). The reason is that the force is not grounded. If the strength is not grounded, the strength will not be rectified. If the strength is not perfect, it will be difficult to resist the opponent's attack, and it is also difficult to attack the opponent. It can be said that the effectiveness of the punch cannot be separated from the hip.
4. How to open the crotch
To open the crotch, several large tendons (tendons) that lock the crotch must be loosened. This is not easy to do, but it is still possible. On the Internet, you can see some people who practice soft skills (cartilage skills), and the hip joints can almost do 360-degree movements like a cardan shaft. Practical boxing does not require such a large range of motion for the hips, but only requires an increase in the range of motion in a specific direction, which is the direction where the knee connects with the pubic area or the tip of the hip on the other side.
The crotch is in the position of the middle section in this group of relations. According to the principle of three-section movement, the two root tips must be pulled in opposite directions, and the middle section must move toward the root tip connection. Take the side horse step mentioned above as an example, hold the front knees still, turn the waist and pull back the dantian, and push the front hips forward and upward. Boxers who have practiced basic skills will know at a glance that this is actually lifting water. Of course, it is impossible for the knee to stay still when the crotch is not open, so you can only do as much as possible.
It is about opening the front crotch, so if you want to open the back crotch, how should you open it? In fact, the method is exactly the same as the front crotch, but the direction is different. Specifically, the tip of the front hip is fixed, the back knee is held outward, and the back hip moves toward the connection of the two, moving forward and downward. The opening of the hip can be regarded as a reverse lifting.
5. Waist and crotch conversion
Finally, talk about waist and crotch conversion.The so-called waist and crotch conversion actually refers to the conversion of body support between the two hips. Waist and crotch conversion has important offensive and defensive significance, so you must pay special attention when slinging. Every action should be clear which leg is the supporting leg and which leg is the exerting leg.
Generally speaking, the front legs are supporting legs. Here, the front and back are determined by the direction of the torso and the direction of force. For example, the second movement of the right forehand circle, turn the waist to the left, and then the left leg changes For the front legs (support legs), the same is true for the fourth movement of six seals and four closures.
The crotch of the supporting leg should be lifted upwards, as close as possible to the opponent, which has two functions: One is to help the opponent's force to leak to the ground through the hind legs to stabilize itself; the other is to wedge the wedge under the opponent's line of force to facilitate prying Move each other. Therefore, the position of the hips is usually high front and low back.
As mentioned earlier, the front crotch should be lifted up, remove the hard bends, and the crotch bends will become rounded. He also said that the back crotch should be opened so that it can be connected up and down. In this case, don't both hips have to be opened? is it possible?
I used to think that the two crotches are always open and close at the same time, and cannot be opened at the same time, but recently I have a different opinion: if you know the method, the two crotches can be opened at the same time.
This method is to wrap the hips. After the hips are wrapped, the position of the pelvis changes from forward to upright, and both hips may be opened at the same time. To wrap your hips, you must first loosen your waist. Once your waist is loosened, your hips can be wrapped. When your hips are wrapped, your crotch will be rounded.
