Human organs are very important to us, each of them. For fitness people, the buttocks are naturally also a very important one. In fact, the human butt is very peculiar, unique in nature, and it is the most important sign of our evolution from apes to humans.
Human ass
The buttocks are the junction of the waist and legs in the human body, in which the hip and sacrum make up the pelvis. Men and women do not have the same hip size. Women have fuller buttocks, compared to men's smaller buttocks.
We say that human ass is unique in nature, why is that? In fact, the human buttocks are made up of the gluteus maximus, subcutaneous fat of the gluteus meso, and a layer of external skin. Compared to other mammals, the most important part of the buttocks in humans is the gluteus medius. Even animals such as chimpanzees, which are closely related to humans, have different hips than humans.
Why is human ass so special? The most important factor may have to do with the way humans move. Humans are mammals that walk entirely on their legs.
Researchers have found fossils of the archaeopteryx species, which is one of the ancestors of humans, and its pelvis is very close to humans. As we said above, the crotch is a part of the pelvis, which in turn is composed of the ilia, pubic bone and ischia, which will gradually merge with the evolution and development of humans.
When the pelvis changes, so does the gluteus maximus, which is close to the middle and develops with the upper thigh bone to support the trunk associated with it. It is precisely because of this function that humans can exercise the gluteal muscles from some sports, which not only changes the iliac bone, but also slows down the resistance, and also makes the crotch more flexible, so that more complex movements can be made.
Some of our daily simple movements, such as standing, rely on it. This is exactly why if we sit for a long time, the crotch will be grated, so that the buttocks will increase fat in order to better protect the hip bone and other parts.
The buttocks are rich in fat and also provide energy for humans. In the process of human evolution, the buttocks, chest, etc. are all places where the human body stores energy. In other apes, it has a similar role, but there are differences after all.
The hip can be counted as one of the most important signs of the evolution of apes into adults, which both freed human hands and at the same time allowed the brain to evolve to distinguish humans from other animals. Even in primitive society courtship, the buttocks are also very important, because people will judge whether a person is healthy or not by the state of the hips.
Other aspects of the buttocks
Actually, when it comes to human asses, there's a lot more to it related to. In modern society, people pay more attention to their own health, so many people choose fitness, first, we can exercise, second, both men and women, everyone also wants to have a good body.
Some fitness people may be very concerned about their hip circumference or waist-hip ratio, in fact, in terms of hip circumference, on average, the gap between men and women is not too big.
In terms of waist-hip ratio, the difference between men and women is very obvious. First of all, the waist-hip ratio is the ratio between waist circumference and hip circumference, in which the average of male waist circumference is greater than that of women, and from the perspective of waist-hip ratio, men are also greater than women's, which shows that women's waists are thinner and their hips are relatively larger.
In modern society, we often see the term "false crotch width", and it is generally mistakenly believed that the iliac crest width is the maximum width of the crotch, and the greater intertrochanteric width is greater than the iliac crest width due to internal rotation of the femur. Such a statement is an erroneous description of the specific location of these three parts.
The iliac crest should be located in the upper part of the pelvis, which is approximately in height to the umbilicus height, while the iliac crest point is the widest point of the iliac crest on both sides and the most protruding point of the iliac crest. So where should the correct position of the large rotor be?
We abduct the thighs and bend the body to the side of the abducted thighs, creating a depression in the skin of the greater trochanter. When lying on its side, the large trochanteric of the femur rotates inward, which can cause false bulges.
What we call "false crotch width" is characterized by the fact that the width between the iliac crests is less than the width of the greater trochanter, and then the width of the greater intertrochanter is less than the maximum width of the hip.
Women have more fat in their thighs than their calves, so they form a fat pad on the outer thigh, which is located on the upper surface of the outer thigh. It fuses with the fat pads at the back of the buttocks and then with the part of the buttocks that extends downwards.
Among them, the widest part of the female pelvic area is composed of fat pads on the outside of the thighs, because women have more fat in their thighs, which will lead to an increase in the width of their hips, so women's legs will also look shorter than men's.
When there is too much fat under the trochanter, the outer thigh will bulge, at this time, the maximum width of the hip is larger than the width of the large intertrochanter; The position of the widest point of the hip is low compared to the lateral trochanteric projection, but this is not due to internal rotation of the femur to form a false crotch width.
In fact, we can also reduce the subtrochanteric fat by some means, so that the maximum width of the hip is reduced to be closer to the greater intertrochanteric width. However, the width of the large intertrochanter in normal people is always greater than the width between the iliac crests.
There is also a condition where the technical term is called hip varus. If this is extremely serious, it will cause the large rotor to protrude and rise, and there will be conditions such as hindered internal rotation activity. In this case, the interiliac crest width is much smaller than the greater intertrochanteric width, and the greater intertrochanteric width is equivalent to the maximum width of the hip.
Under normal circumstances, the height of the external protrusion of the greater trochanter is close to the height of the gluteal peak. However, in this case, the height of the large trochanter is raised again in the original situation, so the widest point of the hip is higher than that of normal women. Therefore, the statements about "false crotch width" showing short legs are completely inconsistent.
So whether it is for the purpose of exercise or otherwise, we must decide how we should exercise after a detailed understanding, after all, the body is the first, with a healthy body, we can do everything we want to do.
Other parts of the human body
We often say that the eyes are the window of the heart, and for us, it is very important to have bright eyes. However, in modern society, because people frequently use their eyes and do not protect their eyes well, it has threatened eye health. Nowadays, there are several common eye problems in mainland China.
The first is eye fatigue, which is already a very common disease in ophthalmology, and its manifestations are not single, but diverse. However, most patients have transient visual loss after a long period of close eye use or eye use, and there may be a series of discomforts in the eyes.
Patients with mild conditions usually have swollen and dry eyes, but patients with more severe conditions will have swollen eyes and severe headaches. Therefore, no matter which of the above conditions, you must seek medical attention in time, if you do not get timely treatment, it will cause vision loss, neurasthenia and other consequences.
Then there is myopia, which is a very common refractive error. There are roughly three reasons for its formation. After entering modern society, this has become an eye disease with a high incidence worldwide, and it has been listed as one of the eye diseases that urgently needs to be solved. And nowadays, myopia has shown a trend of "younger and younger age of onset", and adolescents have become a high incidence of myopia. Therefore, you must use your eyes reasonably and pay more attention to rest.
In addition, there is cataract, according to relevant statistics, there are now 15 million patients blinded by cataracts in the world. According to the analysis of the continental census, about 4-5 million people suffer from cataracts. It is lens opacity caused by various causes. And its formation of a variety of reasons, in addition to such as metabolic or congenital, such as more obvious causes, there are other reasons, in short, the situation is very complex. Among them, our most common senile cataract is related to aging and other conditions.
The third place to be blinded due to eye problems is glaucoma. According to different reasons, it can be divided into three categories: primary, secondary and congenital. It is characterized by optic nerve atrophy and visual field defects. Among them, its production is related to the level of increased intraocular pressure, etc., in addition, diabetes is also its most dangerous factor.
The second leading eye disease is fundus disease. Because of its irreversible characteristics, it is a major difficulty in the prevention and treatment of ophthalmic diseases today. The health of the fundus is closely related to vision. Among them, there are two most common, one is age-related macular degeneration, which is related to long-term chronic photodamage of the macula; The second type of diabetic retinopathy is caused by causes such as elevated blood sugar.
Due to the increase in the time we spend using electronic products for work or entertainment, and many people lack the awareness of rational eye use, eye diseases have become extremely serious today. We need to see this beautiful world with our eyes, so for the sake of good health, we must also use our eyes reasonably and rest more.
summary
Every organ in our body is extremely important to us. In today's society, whether it is too busy with work or other reasons, some people lack the awareness of exercising their bodies, so there are many diseases gradually gathering towards young people.
For example, osteoporosis may sound incredible, but nowadays, there are indeed many people under the age of 50 who suffer from osteoporosis. The main reason for this is low activity and lack of vitamins in the body. So we eat more foods like dairy and then do more aerobic exercise.
Then there is stroke, even young people should pay attention to this disease, if you have high blood pressure, obesity and other conditions, it will increase the risk of stroke. Therefore, in ordinary life, we should pay attention to controlling the salt content of food, and then stay away from cigarettes. Because once the attack occurs, the consequences are very serious.
There is also type 2 diabetes, which is now more and more young people suffering from this disease, and its cause is related to diet and activity, of which obesity is also one of the reasons.
There are many such diseases, in addition to some genetic diseases, most diseases can be prevented, although exercise can not completely prevent the effect, but can improve the body's resistance, so as to be able to resist these diseases.
There are also many obese people who want to lose weight, and reducing the amount of diet is certainly a method, but after all, it is not as reassuring as exercise. Because if you are overweight, it is not good for the body, and weight loss is not only to lose weight, but also to hope that everyone can have a good body. So we can choose to lose weight through exercise.
Only when we have a good body can we do what we want to do and where we want to go. Fitness is not only able to have a good figure, but most importantly have a good body. We often say that the body is capital, and this is true.
