Shoes are an indispensable supply of modern human life. The ancient saying goes: A thousand miles begins with a single step. Without shoes, it is almost impossible to imagine. If you mention the science of shoes, people must first think of sports shoes. Of course, in 1960, Ethiopian marathoner Abebe barely won the world championship, but with the retreat of sports technology, the period of barefoot is now gone forever. In ancient competitive sports, sports shoes are boots and equipment. The manufacturers' development of sports shoes is no less than that of martial arts competitions. It can be described as cost-effective and costly. The cost of a pair of running shoes can be as high as tens of thousands of dollars. Superstitious design of sports shoes At the beginning of the soles, different sports and even different venues have different requirements for soles. Therefore, many sole components can be easily replaced to prepare for continuous needs. Liu Xiang, a famous hurdle transport player, had a long-term resolution to change the short nails of running shoes before the competition, and achieved satisfactory achievements. He also said that the spike was his "secret weapon."
As the saying goes, life is in sports. Ordinary people's standing walking is also a kind of exercise. Should there be corresponding health equipment? Since the person is a vertical position, the entire weight is burdened by two legs. When standing and walking, shoes and feet must be combined into an organic whole. So whether the science of the average person's shoes is also in the soles of the shoes, unscientific design is not only detrimental to daily life, but also harmful to health. The classic is a series of foot problems caused by high heels. At the same time, high heels also directly affect the health of the spine. Therefore, doctors are particularly reminded patients with low back pain, cervical spondylosis, we must pay attention to the choice of shoes, avoid wearing high heels. This is a major issue related to human health. Therefore, the study of life shoes is far more important than the study of sports shoes.
The relationship between people and shoes is, for example, the relationship between the building and the foundation. Any one construction will not be careless about the design of the foundation. The Society for Construction has also set up a basic branch of the foundation to conduct in-depth research. For shoe design, it has never been so strict. The obsolescence and stereotyping of traditional viewpoints have seriously hampered the development of shoe research and caused more problems that are detrimental to health. Clinical materials show that "in addition to congenital malformations, many of the foot diseases are acquired acquired podiatric diseases. According to calculations, about a quarter of the world's people are suffering from different degrees of foot disease." The medical community confirmed that all foot Disease has a direct relationship with shoes. And a large amount of data confirms that barefoot is more beneficial to the health of the foot. In other words, from the point of view of the health of the foot, shoes are harmful and useless. Due to the long-term failure to find a true cause and countermeasures, she had no alternative but to call it "wild disease." This is undoubtedly a great sarcasm for highly developed modern science.
Love and hate cross-heels
High-heeled shoes are the love of fashion motherhood. It is as gorgeous and magnificent as artwork. But the feeling of wearing it at first, must be cautious, like walking on thin charcoal, as the song sings: "High heels stepping on a steady pace." With the torture-like suffering, various kinds of lesions follow. In terms of shoes and health issues, the damage to health of high-heeled shoes is the most exemplary and prominent. It is mainly manifested in the following aspects.
Forefoot disease. Hallux valgus, interdigital nerve tumors and other common forefoot diseases are all related to moderate stress. High-heeled shoes move the body's center of gravity forward, and the force on the soles of the feet has multiplied, and in the long run it will certainly cause illness. Once these two kinds of diseases are constructed, walking ability will be greatly affected, even deformed wearing shoes are very difficult. In addition to surgery, there are currently no better measures for resolution.
Flatfoot disease. Deciduous relaxation is an important cause of flat foot disease. It is located on the sole of the foot and acts like a bowstring to maintain the stability of the arch. The higher the heel, the longer the arch of the forearm, the greater the tension (tension) of the diaphragm. If the long-term tension is too large, the aponeurosis relaxes and the arch decreases, causing serious flatfoot. The relationship between the height of the heel and the pulling force on the diaphragm is clearly reflected in the structure of the sole. Many of the shoe's heel areas (which are equivalent to the aponeurosis) have a steel plate called the "hook heart." It is used to reinforce the sole. The higher the height of the heel, the higher the requirement for the strength of the steel hook. Otherwise, the sole will be easily broken. The shoes without the heel must not use the hook. The higher the height of the heel, the more steel soles are needed to strengthen the soles of the soles, and the human aponeurosis is reluctant to reinforce. Is this not terrifying?
Ankle injury. Ankle joint injury commonly known as "bad feet", wearing high heels and feet has become commonplace. As the ordinary people walk and exercise, the ankles tend to produce an inward turning force, and the outer side of the shoe is always the first to wear. The person himself is also constantly adjusting this turning force in order to maintain a balanced, but after putting on high heels, the adjustment ability will be weakened, and it will easily lead to lameness. And the higher the heel, the greater the potential energy to turn inwards, and the severity of the injury increases.
Back pain and cervical spondylosis. An important reason for low back pain and cervical spondylosis is that the curvature of the spine is too large. Because the spine is made up of multiple vertebrae, the contact surfaces of the two vertebrae are almost three-dimensional. When the posture is upright, the vertebrae are in contact between the face and the face, the force is evacuated, and it is not easy to damage; when the spine is bent, the contact surface between the vertebrae becomes smaller, the force tends to concentrate, and even concentrates to one point, and the pressure increases rapidly. Large, it is very easy to damage the vertebrae. High-heeled shoes make the person's center of gravity excessively advance, inevitably cause the pelvis to lean forward, the curvature of the spine increases, and the concentration of the lumbar vertebrae and the cervical spine is easily damaged. The accumulation of this kind of injury will eventually lead to the occurrence of low back pain and cervical spondylosis.
Paradoxical heel shoes
For a long time, heel shoes have always been considered to be the most conducive to health, and there is no adverse effect, and high heels become a shocking pole. In the footwear industry, it is regarded as a disciplined discipline. Designers try to make their products fit the standards and standards in order to sell well. Consumers often choose mid-heeled shoes for health reasons. Those women who are afraid of high-heeled shoes have a special liking for mid-heeled shoes that can also sway. In this way, heel shoes naturally become the mainstream product of footwear.
However, this theory can not help but sometimes make people suspect that heel shoes and high-heeled shoes are added at the back of the sole. Although the height is different, it is difficult to draw a relative boundary. For example, a 3.5-centimeter high heel, some people think that it is high-heeled shoes, some people think that is in the heel, at first there was a "middle high heels" transitional title. Since there is no absolute boundary, how could it have the opposite effect? Is high heels a bad health enemy, and just a little lower heel is a health angel in the ointment? Judging by suspicion, the problem is even greater.
The center of health theory of heel shoes is: It can make the force of the sole of the foot become average. It seems to be very simple to explain: high heels make the force of the soles of the feet larger than the heels, which is naturally unfavorable to health; while flat shoes, the weight of the heel is larger than the soles of the feet and is not suitable. Only the heel shoes make the force of the feet even, so it is the best.
In fact, only by looking at the foot anatomy can be learned that the structure of the foot is obviously not uniform, ad abdomen exercise machine, large and solid calcaneus, muscle ligament strong; and the front foot bones, muscles and ligaments should be weak Much more. From the perspective of human brain mechanics, calcaneal bones are approximately vertically superimposed, structurally stable, and smooth in gravity conduction; while the forefoot bones are almost horizontally aligned and must be supported by the strength of muscles and ligaments when bearing, and are elastic structures. Deformation, not suitable for bearing. In short, no matter from which point of view, the forefoot's weight bearing capacity is far behind that of the hind foot, and it is not reasonable for the front and back foot to bear the same pressure. The symmetry does not mean justice. It will certainly damage the delicate parts, which is also the reason why podiatric disease mostly occurs in the forefoot.
Look at the so-called second strength of the heel, that is, to slow down the vibrations, maintain the spine and the brain, and how to get red blood on the face. The disease caused by vibration, known as the vibration disease, causes the nervous system's efficacy to fall, conditional reflexes to be restrained, nerve endings to be damaged, and shock sensation and pain sensation can be obviously reduced. Expressed as arm numbness, sourness, pain, and ant feeling, the major will also show arm skin ruddy, cyanosis, hand muscle weakness and muscle atrophy, the results are more severe. However, vibration disease is an occupational disease and it is the result of long-term stimulation of human body by high-frequency mechanical vibration. More often found in flexible vehicle drivers, for example, the frequency of vibrations suffered by a dragging machine is as many as 50 times per second, and high speed gears can be hung up to 100 to 200 times. The vibrations and the shocks of human movement are two completely different concepts.
In order to prevent fear of vibratory disease, the fourth (Human Body Vibration Response) subcommittee of the No. 108 (Mechanics and Vibration) Skills Committee of the Domestic Standardization Organization specifically studied the impact of vibration on human health, and finally concluded that “walking and driving are natural The method of exercise, in particular, the work of approaching the muscles, can be considered that the emergent vibration stress should not have a detrimental effect under normal circumstances, in order to lose the indication of the vibration characteristics of the human body in an upright position, when compared to walking or running The human reaction caused by vibration is beneficial.†Since this kind of vibration is beneficial, why should the heel shoes guard against it?
It is boring that the earliest heel device was not designed for walking but riding. When horses are nomads, the heels can keep their feet firmly in the stables, and they can stand up and apply their weapons during the battle. The advantages are obvious. Following the taming of the nomads across the country, shoes with heel gradually spread and were generally accepted. This is for practical needs and is the only function that can be carried on the heel.
From the perspective of the human body, heel shoes and high heels are no different. According to scientific classification, heel shoes and high heels should be called heel shoes. If high-heeled shoes are particularly harmful to the human body, then heeled shoes are moderately harmful, especially to developing adolescents and middle-aged and elderly people who are in decline.
After the issue of heel shoes was clarified, at present, the death of a severely revived foot disease known as "cultural disease" was also solved. The damage to the heel shoes is not as obvious as the high heels, but after all the increase, it will cause illness. Even more worrying is that this effect is still intensifying. In recent years, the list of weight loss products, sports shoes manufacturers have launched new styles of heel shoes, in the heel shoes health theory, more and more people have switched to heel shoes for physical exercise, which is very dangerous. I hope this question can be raised and clarified, which can lead to some emotional reflections.
Heels and high heels are collectively referred to as heel shoes. Absolutely in terms of the role of the human body, there is no real difference between the two.
Natural child flat shoes
Since the higher the heel is, the more harmful, is there no flat heel or barefoot sole that is completely harmless? A large number of medical practices have shown that barefoot is more conducive to the health of the foot than wearing shoes, but the skin is easily damaged. Flat shoes can obviously supplement this deficiency, and they can also maintain the mechanical state of barefoot. This is also the most natural and natural state of mankind, which is consistent with the mechanical structure and movement laws of the human body.
However, in recent years, many articles have been launched against flat shoes. It is believed that wearing heeled flat heels is overburdened and can easily cause heel damage, and flat shoes have poor shock absorption and affect the health of the spine and brain. Like the health theory of the heel shoes, this is also unscientific.
In fact, when standing barefoot and wearing flat shoes, although the force of the heel is larger than the sole of the foot, it fits the mechanics of the foot and does not damage the heel. Later, we have analyzed the theory theoretically. Now let's take a look at the theoretical situation. The foot injury caused by excessive exercise is clinically known as "trouble fracture", also called "foot march." It was named after soldiers who walked on the road. The disease is more common in racing, walking and gymnastics and textile workers, porters. Its main damage is in the forefoot of the sacrum (especially the second and third metatarsals) and its surrounding soft tissue. This also proves in practice that the bearing capacity of the heel is far greater than that of the soles of the feet, because the first thing that is damaged is always the front foot. If you wear heel shoes, the forefoot injury will undoubtedly occur earlier and worse. The heel is much stronger than we think. Most of its damage is caused by intentional injuries or accidents such as falling at high altitudes. At the same time, it is accompanied by multiple fractures such as the spine pelvis and is not a sports injury. People often wear heels, and occasionally wearing flat shoes may cause heel pain, patients who stay in bed more obvious, this is the lack of weight on the heel for a long time, the result of atrophy of the foot fat pad, will quickly dissipate after adaptation.
Look at the disadvantages of shock absorption. Research and discussion of prestige agencies has proven that vibrations caused by the movement of the human body are not harmful to health but are beneficial. When we are engaged in strenuous exercise and heavy labor, the vibration is determined to be much larger than that of our daily life. Isn't everyone wearing flat shoes? If wearing flat shoes really hurts the spine and the brain, how do early humans walking barefoot survive?
Reasonable negative heels
So, is there any kind of shoe that is mechanically beneficial to human health? Based on the previous analysis, we naturally think of high and low shoes. We have long called this type of shoes a negative heel. In fact, negative heels are no longer imaginary, and they have been on the market for several years, but they have always been famous.
There are many types of negative heels and manufacturers. The following three are representative: the United States Earth shoes, Hong Kong's slim fitness shoes and Beijing's physical training shoes. The function of these three types of shoes is basically the same as that of a gentleman's body, which makes the spine upright.
"Earth shoes" stems from the perception of a yoga instructor who invented the local people's body to be particularly upright and fit. During her inspections, she paid special attention to the footprints of the locals left on the beach: the deep depth of the heel. Thus, a kind of shoe with a high back and a low front was manufactured. After wearing the shoe, he felt straight and straight, and he had the clever effect of "Lotus Seat" in yoga training. It is also very quiet when you walk, and it seems to be the general enjoyment of “walking barefoot on the beachâ€. Earth shoes have been extremely widespread in the United States. More than 500 sales terminals are scattered all over the country and exported to many countries and regions. The upsurge of walking and fitness in the western countries is also providing a vast market for Earth shoes.
The founder of "Slim Fitness Shoes" is a senior female executive of a footwear international business company in Hong Kong. She found that the front and rear soles of the soles of the squats were able to stand upright and have a significant weight loss effect. This has also attracted a great deal of interest among scientists. For the purpose of scientific research, Professor Hong Youlian of the Department of Sports Science, The Chinese University of Hong Kong (presently the vice chairman of the International Sports Biomechanics Society) and Dr. Li Jingxian, Scientific Director of the Human Exercises Laboratory, presided over the exercise. Body shoes research and testing. Through photographic records, electromyograms, energy costs, breathing. Has been monitoring, plantar force analysis and other equipment and wrists, carried out six items of target tests. Studies have confirmed that high and low physical fitness shoes in front of the soles of the shoe can make “the trunk is significantly straight, strengthen the back muscles, and assist in correcting standing and walking posturesâ€. "Slimming effect" has also been fully proved, so fitness shoes, also known as "slim fitness shoes." At the same time, it is also intended to discover locally that “when wearing this kind of fitness shoes, the change in human posture will reduce the impact force generated when the foot touches the airâ€, which undoubtedly has a protective effect on the foot.
The trainers of physical training shoes are well known for their theoretical research, conduct profound research from multiple angles, and publish many academic papers. Physical training shoes, as the name implies, are used to vilify form. The posture of ballet dancers is undoubtedly the most perfect. What is special is that their torsos are much more straightforward than normal people. People in the industry call it "unnatural posture", which is an important condition for becoming a ballerina and the highest level of human beauty. Ballet body training requires the feet to open 180" in a "one" shape, and the center of gravity moves back to the heel, and the person will form an unusually tall and straight posture. The principle of the body training shoe is the same, because the sole is high and low. In the same way, when the body weight of the person is forced to move to the heel, the posture immediately becomes tall and straight. In this way, people's standing and walking in daily life all have the meaning of physical training and transform body training into a part of life. The methods have been promoted as teaching materials in the dance industry, and physical training shoes have been favored by body lovers (especially postpartum women), and they have been called “lazy body training methods.†Enemies who have not been exposed to such shoes, If you are interested, you can verify it with two small experiments: keep everyone's body in shape (like standing on a wall), understand if the center of gravity is on the heel, stand barefoot or flat shoes, and put a 2cm thick under the front foot. Book, feel if the posture is taller than usual.
Physical training shoes also have medical implications. We all know that the basic cause of low back pain and cervical spondylosis is the excessive twists and turns of the spine, which is the most basic form of treatment. Healthy body training is a treatment for low back pain and cervical spondylosis. The healing effect of physical training shoes can also be explained with difficulty by using "falling away". Surgeons usually advocate for patients to “pump away†(regressive walk) exercises, actually confirming the good results. As with the principle of physical exercise, the role of the reverse is to shift the person's center of gravity back to the heel. However, there are many preconditions such as road conditions, and it is easy to fall down. It is precisely because of the existence of these hidden dangers that it is difficult to take a long time to exercise and the effect is naturally limited. Physical training shoes solves this problem. It limits the weight of the person's body of weight to the heel for a long period of time. This means that when you walk forward, there is also a rehabilitation function. You can tell how to lose weight fast and healthy. This latest method of low back pain rehabilitation is known in the medical community as "low back pain foot therapy."
Maybe some people will take away or wear shoes with heel health violations. It is really unnecessary to worry about this. Take ballet dancers as an example. Although there are many ballet movements, there are only five foot positions, which are called five positions. Each foot position requires the feet to turn outwards (ie, horizontally). At this point, the body's weight is almost on the heel, and it is more stressful than wearing a negative heel. At the same time, intense activities are required. Even so, the ballerina's heel will not be damaged. In the history of ballet for hundreds of years, there is no record of damage. Therefore, this worry is unnecessary, and the focus of the upright person is on the heel.
Shoes and health are right and wrong
Abstract: Shoes are essential for people's lives. It can not only promote a collective dress chewing, but also with our health and non-friends.
