Liao Nanxing stood up from the chair and walked to the open space of the restaurant, thinking about what Wu Lang said in his mind, he practiced the secret technique of rehearsing the teaching, his body looked like a tiger, with the swing of his back, the internal strength was transmitted to the arm, and he looked a little jerky and restrained, and then his waist and hips shook for a while, and he wanted to transmit the strength to his legs and feet, but he did it several times in a row, but he couldn't be coherent, and then, a little disheartened, he walked to the dining table dejectedly, sat on the chair, and drank a sip of "men's blood".

Wu Lang patted him on the shoulder with a smile and said, "Don't be like this, I'll tell you the method, as long as you work hard, you can do it soon." ”

"Really, then you can say it quickly!" Liao Nanxing raised his head suddenly, looking at Wu Lang expectantly.

Liao Aotian, Mrs. Liao, and the Zuo brothers all laughed in unison.

Wu Lang nodded, looked at Liao Nanxing, and said: "Look, for example, when using a fire hose, if there is a twist or bending, it must be straightened out in order to make the high-pressure fire extinguishing agent pass smoothly. When the internal strength passes, if the joint can not be straightened out in time, the transmission of internal force will be blocked, taking the shoulder joint as an example, the arm is basically folded with the spine, in the actual combat state, even if the trained person will not open a large angle, this state is obviously not conducive to the transmission of internal strength, so it is important to open the shoulder joint in time when the internal strength arrives, which depends on the help of the joint extensor muscles, and whether the joint can be opened in time depends on your usual training level. Therefore, to open up the strength of the road, in addition to the joint opening and closing exercises, but also to train the joint extensor muscles, so that the fascia can be raised in time when the internal strength arrives, and the joint can be opened, otherwise, the internal strength can not pass smoothly, if there is no strength, that is, the strength of the road somewhere is not opened, at this time, it should be considered, whether the joint can not be opened and closed or the fascia can not be opened. ”

Liao Nanxing nodded slightly, silent in thought, and listened carefully to every word Wu Lang said.

Liao Aotian and Mrs. Liao looked at Wu Lang's demeanor of carefully teaching their son, and nodded frequently, their eyes full of relief and gratitude.

Liao Jiayi looked a little drunk, her right elbow was on the dining table, her chin was supported by her palm, her head was tilted, her eyes were confused, and her two dirty feet were still rubbing on his white shoes.

"You see that the design of the soft whip is from thick to thin, the whip body will have a transverse wave movement when the whip handle is shaken, and the fluctuation amplitude is getting bigger and bigger, the faster the speed of the transmission to the finer part, and when it reaches the end, it will reach supersonic speed, and it does not require much effort to hit people with a soft whip, and it makes the enemy elusive. There are three links in whipping, first, straightening out, second, pulling back, and third, throwing forward. The same is true for the horizontal force transmission, but because your arms and legs are not as soft as the whip, so there is no long-term effort, it is impossible to achieve this effect, the combination of horizontal strength and straight strength, is the so-called spiral strength, when the strength of the limbs is opened, the power of the dantian will be transmitted along the legs to the feet, at this time to kick the ground, the feet will feel extremely difficult, this is because the wave will be reflected when encountering obstacles during propagation. The incident wave is also the propulsion wave, and the wave formed by the interaction with the reflected wave is no longer propulsive, and only vibrates up and down the belly of the wave, and the wave node does not move, which is called a standing wave. Standing waves in tsunami occur in front of a steep coastal wall or an upright hydraulic structure. The mechanical wave that goes down along the leg will also form a standing wave when it encounters the reflection of the ground, and the amplitude of the wave at this time is twice that of the downward wave. After Wu Lang finished speaking, he picked up the big bowl, raised his head and drank it all.

On the ground, Liao Jiayi got up from the chair, hurriedly poured the "men's blood" for Wu Lang, took out a cigarette from the cigarette case, lit it in his mouth, and handed it to Wu Lang, with thoughtful service and attentiveness.

"If you smoke less, your lungs are already a little black, which is not good for your health. Wu Lang glanced at her and took the cigarette.

"You can see through my body, wow, this one is even more powerful!" Liao Jiayi's beautiful eyes widened, staring at Ah Lang, looking up and down.

Immediately, Wu Lang turned his head, smoked a cigarette, and stopped looking at her.

On the ground, Liao Jiayi stood up from the chair, patted Wu Lang's shoulder, and said, "Brother Wolf, then you give me a good look, where are there any defects in the body, or what are the deficiencies?"

"It's all good, just smoke less in the future. Wu Lang didn't look at her, bowed his head and drank "men's blood".

"My good sister, can you stop the meeting, I just feel a little bit at this time, you just make trouble, let Alang finish telling me, you toss again, count me begging you!" Liao Nanxing looked at his sister with a bitter face and said.

"Okay, Brother Wolf, you go on, let's have a private chat for a while. After Liao Jiayi finished speaking, she sat next to Wu Lang with a smile, and her two dirty feet continued to rest on his white shoes.

Wu Lang looked at Liao Nanxing and said with a smile: "Since ancient times, there has been a saying that "strength starts from the feet, dominates the waist, is well-versed in the back, is shaped in the fingers, and originates in the spine", whether the strength originates from the feet or the spine? Obviously, this statement is self-contradictory, the strength under the feet mainly stems from the reflection of the earth on the downward mechanical waves, and the power of kicking the ground only plays a role in fueling the waves, and some of our common clever boxers sit on the chair, and they can beat people out without force under their feet, which shows that "strength starts from the feet" It is a misunderstanding, in fact, the folding of snakes, the swimming of fish, the fight of beasts, the fluttering of birds, the movement of all beasts, the strength of all things comes from the backbone, the eagle strikes the sky, the fish soars to the shallow bottom, and the force is certainly not with the feet! The dantian force is reflected to form a standing wave plus the limb force of kicking the ground, and then it is synthesized with the power uploaded by the dantian to act on the opponent's body, and its striking power can be imagined. In the same way, our punches and kicks also reflect when they meet the opponent's body, and when the direction of the blow force is perpendicular to the part of the blow, it also forms a standing wave, so in order to achieve the best striking effect, we must strike vertically. ”

"There is such a complicated truth in this!" Liao Nanxing exclaimed.

Liao Aotian and Mrs. Liao, and the Zuo brothers were also slightly pondering, and then looked at Wu Lang and nodded frequently.

Suddenly, Liao Jiayi looked at Wu Lang and asked, "Then how exactly should I practice?"

Wu Lang nodded at her appreciatively, and said with a smile: "You are too smart, this is divided into vertical strength, horizontal strength, Special exercises, vertical strength can be naturally opened with both feet, slightly wider than the shoulders, both hands hold fists such as Thai, inhale and lead the waist to raise the heel to turn the crotch, the left fist with the left heel, the right fist with the right heel, exhale and shake the whip handle, take the left hook as an example, when the strength is uploaded to the upper arm, the left arm is rotated inward, that is, clockwise, so that the heart of the fist is naturally hooked inward, do not use clumsy force; the right fist is placed in front of the abdomen; down to the feet, the heel is stepped down, the left and right alternate exercises, four or eight breaths can be, remember to relax the body, do not be nervous, practice to the fist or heel, you can. Horizontal strength is the breath is long and even, the movement is loose and slow, the feet are naturally open, slightly wider than the shoulders, the hands are drooping, inhale in the dantian, and then make the golden gate slightly raised, exhale at the same time violently contract the respiratory muscles, forcing the lumbar spine from lordosis to kyphosis, with the shaking of the spine, the strength is first transmitted from the hip joint down to the knee, then the knee is pushed forward; uploaded to the head, the head is leaned forward; after the shoulder joint is transmitted to the elbow, the elbow is propped outward, and the beginning should be less practiced, and then added to each four or eight breaths, more practice for fear of injury. When you practice as slowly as you want, you will be able to experience the coordination and rhythm of various muscles and joints in the process of exerting force. At this time, as long as you lift your breath and exert force, your elbows and knees can be shaken out in an instant. The special exercises of transmission of strength should be practiced according to different techniques, and if you find that the action is not strong, you will practice the strength of which action alone, take the elbow as an example, Thai standing, when the internal strength goes up to the shoulder, the elbow tip is picked up, the left and right sides alternate, and the four or eight calls are a group. Any macroscopic or microscopic physical quantity, the disturbance can form waves when it is transmitted in space, and the premise of producing these waves is that there is an elastic force or quasi-elastic force interaction between the adjacent particles of the medium, and it is with the help of this interaction force that the vibration of a certain point is transmitted to the adjacent particles, so these waves are also called elastic waves. ”

Liao Jiayi looked at Wu Lang with a rare seriousness and seriousness, and said: "How much knowledge do you know, and the internal forces from different perspectives such as medicine, physics, automobiles, machinery, etc., are easy to understand, concise and concise, and clear, I doubt that you are studying Chinese medicine?"

"I'm a high-achieving student who graduated from Haizhou University of Traditional Chinese Medicine ahead of schedule, so I can't fake it. Wu Lang said with a smile.

"Aaron, you go on, ignore my sister. Liao Nanxing said.

Wu Lang nodded slightly, and said: "The dantian jin has come out, the spine has opened, and with a little practice, it can be used for the head, shoulders, and hips." But to continue to pass on, you have to open the shoulder hip, the importance of the shoulder hip, not only the transmission of force, but also an extremely important function, is the amplification of internal strength, although the joints of the human body are diverse, but its basic structure is nothing more than the joint surface, joint capsule and joint cavity. The main factors that determine the flexibility and stability of the joint are the shape of the articular surface, the surface difference of the articular surface, the strength of the ligaments inside and outside the capsule, the involvement of the joint disc, and the strength and contraction amplitude of the muscles around the joint. The tendons mentioned in martial arts are the tendons in the narrow sense, specifically referring to the tendons and ligaments, so the traditional martial arts call the tendons and ligaments the strength of the muscles and ligaments as musculoskeletal strength, and the training of tendons and ligaments is called musculoskeletal training. It is precisely because of the tensile and tensile resistance of ligaments, tendons and muscles that they have a strong and fast recovery force after being stretched, and the articular surface will also produce a certain recovery force after being stressed. It is by harnessing their resilience that our internal strength is amplified. Stronger spring restoring force is also stronger, and due to the peculiarities of the hip joint, it has stronger restoring force than other joints. You see that when archery, the archer opens his bow and aims at the target, pulls the bowstring full, and then gently lets go, and the arrow will use the elastic recovery force of the bow to fly out, which is many times longer than throwing the arrow directly. ”

Liao Nanxing nodded when he heard this, looked at the empty wine bowl in front of Wu Lang, hurriedly got up from the chair, poured him a full bowl of wine, and handed it to him with both hands.

Wu Lang also got up from his seat with a smile, took the big sea bowl handed over by Liao Nanxing with both hands, nodded and smiled, and after clinking glasses with him, the two raised their heads and drank to the sky.

Then, the two sat down, and Wu Lang continued: " For example, put a mud ball on the head of the iron rod, and then hold the other end and shake it, the mud ball will not be thrown out far, if the mud ball is on the head of the thin bamboo pole, just a slight shake, the mud ball can fly far away, this is because when waving the bamboo pole, the far end will try to keep the original state of motion unchanged because of inertia, but the near end is rushed forward due to your force, the elastic bamboo pole is bent and deformed under the action of these two forces, its outer side is stretched, and the inner side is compressed, but because of the elasticity of the bamboo pole, it will quickly return to its original shape to make the bamboo pole straighten in an instant, and finally, the mud pellet will fly out under the action of elastic recovery force, we are using the characteristics of the bamboo pole, skillfully converting the power of the human body into the elastic resilience of bamboo poles. Internal strength can also be amplified in the process of first pulling back or compressing, and then rebounding, which the ancients called "drawing the bow and archery". Drawing the bow is to compress it, deform it, and restore it elastically, but the recovery speed is much faster than the speed of pulling the bow! You see how the brain melon is played, take the middle finger as an example, bend the finger to put the thumb on its nail cover, and then use the contraction of the flexor muscles to pull the extensor muscle and its tendons apart and make the middle finger and the thumb form a confrontation, with the increase of resistance, the thumb slides back and detachs the middle finger, due to the sudden release of the external force, the middle finger instantly recovers to the straight state under the action of elastic recovery force, only listen to the "boom" With a crisp sound, the shell of the brain melon has been hit hard, and the greater the resistance between the two fingers, the heavier the elastic force. ”

As soon as Wu Lang's words fell, Liao Jiayi was on Liao Nanxing's forehead, and she flicked her brain hard.

"Ah, sister, what are you doing, it hurts, you know to bully me one day, you are like this, no one will want you in the future. Liao Nanxing grinned and covered his forehead and shouted.

Liao Jiayi was gloating on the sidelines, giggling non-stop.

Mrs. Liao also glared at her daughter in disgust, got up and walked to her son's side, and looked at his forehead.

Wu Lang shook his head and smiled, and continued: "The characteristics of the bullet, first, is that the short distance, the bullet does not require a lot of space, as long as it is a little distance, it can work. Second, although the strength of the extensor muscles is far less than the strength of the flexors, it is said that it is only one-tenth, but the strength of the elastic is beyond the reach of the flexors in any case. Third, high speed, think about it, in addition to the bullet, what other finger movements will have such a high speed?"

Immediately, everyone lowered their heads and pondered for a moment, and then they all shook their heads and remained silent.

Wu Lang said with a smile: "This is actually the theoretical basis for drawing the bow and archery, taking the horizontal elbow or knee as an example, when the internal strength is transmitted to the shoulder or hip joint, the elbow or knee is not rushing forward, but using inertia to pull back, at this time, the tendons, ligaments and muscles on the side towards the target are stretched, and the muscles on the side of the target should be contracted, so that the stretch amplitude is further increased." Then, with the restoring force of tendons and ligaments, the internal strength is amplified and then hit forward. With the acceleration of the shoulder or hip joint, the speed of the attack is faster and the force is more sufficient, and with such strength, there is no need to say much about the whole strength, because the internal strength is the overall strength. This principle can be used for lateral strikes, such as today's horizontal elbows, whip legs, etc., while the charging method of longitudinal strikes is different. When the internal strength arrives, under the premise that the joint is fully relaxed, the distal end will keep the original motion state unchanged due to inertia, but the proximal end will rush forward due to the urging of the internal force, forming a certain pressure on the joint disc. At this time, the joint cavity is contracted to further increase the pressure of the joint disc, which can be conducive to the elastic recovery force of the joint disc and amplify the internal strength to a certain extent. However, due to the structure of the joint cavity and disc, its range of motion and elasticity are extremely limited, and the amplification of internal strength is not obvious. ”

"Good boy, that's a good point, the two of us did it, but there are some aspects that can't be said, what you said has solved some mysteries in the hearts of my two brothers, thank you!" The Zuo brothers roared and stood up again, both raised the big bowl in their hands, and looked at Wu Lang with gratitude in their eyes.

Wu Lang also hurriedly got up from the chair, picked up the wine bowl with both hands, and signaled to the two of them with a smile, and then the three of them raised their heads together and cleaned the wine in their hands.

"Alang, you continue, you continue, hahaha......" Zuo Qian laughed.

Wu Lang grabbed the cigarette case on the dining table in his hand, took out a cigarette, took a deep breath, and said: "The amplification of vertical strength has to rely on the help of external strength, when the internal strength arrives, the flexor muscles of the joints are moderately recycled to flex them and stretch the extensor tendons, and then use the elastic resilience of the tendons, and the strength of the extensor muscles to quickly open the joint. In general, when attacking outward, the joints on the road are compressed first and then released, and the limbs are bent first and then extended, such as elbows and uppercuts; In this way, the internal force can be amplified with the help of external force, which further enhances the striking power and improves the striking force. The ancients said that when you go out of the hole and enter the hole, you will be close to your body, and you will die if you stretch and stretch your bundle. Among them, the bundle in the word beam is compression and buckling, and the beam is release and stretch. If the arc attack is to loosen the bent steel plate, then the straight line attack is to release the compression of the spring, some ways of playing can have both forces, so, to amplify the internal strength, then in the transmission of force, the middle joint, especially the shoulder and hip joints, must have a first reverse pull, then rebound or first compress and then release the process, which first requires your limbs to be fully relaxed, and then open the shoulders and hips, so that your shoulder and hips can open and close like springs, like steel plates, how to open the shoulders, Crotch, at different stages, the training content of the open shoulder crotch is very different. ”
