Obviously, this is not a concept. In reality, many people don't notice some details at work, such as bending too hard and doing heavy work. In this way, their bodies will get sick if they don't get exercise for a long time, and there are many people with lumbar disc herniation in their lives.
Take my parents for example. They have worked hard all their lives and made no money, but they are all ill. I have been to the place where they work before, and the working environment is very general and the working hours are too long. I've experienced it myself, and I can't stand the intensity at all. Don't say I can't stand standing for a day. The key point is that what they do is heavy physical labor, and people like me who have never worked can't stand it at all. Although exercise is good for health, who can stand this long-term overwork? And keep a posture for a long time, such exercise actually has no real sports effect;
Everyone has noticed that, like those professional athletes, there are also many problems after retirement, mainly because the intensity of exercise is too great. After all, the champion is not so easy to win.
As we all know, at a certain age, people's health will gradually deteriorate, and diseases such as hypertension, coronary heart disease, diabetes and osteoporosis are coming, which has a great relationship with age. Even if you exercise when you are young, you can't escape the traces of time. Aging is an unchangeable fact.
First of all, we should explain the relationship between labor and health. Labor is not equal to exercise, and exercise is not equal to health, so labor is definitely not equal to health.
There is a joke in the fitness circle that it may not last long for Dajiba to do farm work or move bricks on the construction site. This is a joke, because it is true.
Whether it is weight-bearing training or aerobic exercise, we put pressure on the body and muscles in a planned and targeted way during training. Although we occasionally challenge the limits of our muscles, we can all tolerate challenges within our range. And the next day after training, you will stop training or practice muscles in other parts, giving your body enough time to recover. We also attach great importance to nutritional supplements to ensure that the body has enough energy to recover from protein.
Therefore, the premise of getting healthy in sports is to ensure that you will not be hurt in various ways during and after sports.
But what about labor? Take weeding and loosening soil in the field as an example. In the morning, before the sun rises, you go to the fields with a hoe. The job is simple. All you have to do is lift the hoe and hoe the mud in the field. You don't usually take a break. Busy farming hours are usually very tight. You should hoe the ground and sow the seeds quickly, and so on until noon. Cutting crops at noon is not only a five-character quatrain, but also a true portrayal of farmers' uncles.
At noon, people who are close to home usually go home for dinner, and those who are far away from home may bring some dry food to make do with it. After the break, they will work monotonously and hoe the ground until the evening. We have to continue to repeat these tasks the next day.
The so-called labor is like this. When working, the action is single, and a small number of muscle groups are repeatedly tortured; It lasts for a long time and repeats one action a day like a machine. Without the concept of balanced nutrition, eating dry food is also a meal; It won't give the body enough time to fully recover, and it will continue to work the next day.
In fact, long-term work can really reduce the incidence of cardiovascular diseases, diabetes and other rich diseases. But the corresponding price is physical overwork. The incidence of lumbar disc herniation, lumbar muscle strain, rheumatism and other diseases has also increased greatly, which is not worth the loss in general.
So labor is definitely not equal to health. When there are health problems due to childbirth, you should rest in time and treat as soon as possible. Don't comfort yourself and your family with the excuse that you should be healthy if you work regularly.
I remember at a dinner party, a female leader who is also a Kochi said a rather confusing topic. She said that a leader asked a question that day: life lies in exercise, but the tortoise always shrinks its head and does not move. Rabbits are good at sports. Why don't rabbits live longer than turtles? I think this kind of confusion may not be a family statement. Besides, athletes should be good at sports, but according to relevant articles, it is generally believed that athletes will not live long. Most of the long-lived old people in reality are not athletes or hardworking people. One thing, exercise, labor and general exercise are definitely conducive to promoting human blood circulation and digestive activities, bones and muscles. If the intensity of labor and exercise is too high, people will enter a state of fatigue, which is obviously not good for their health. Excessive movement of limbs will cause imbalance of qi and blood in the body and affect the supply of qi and blood in viscera. In addition, when doing farm work, do not pay attention to the influence of sun, rain and wind on human body. Over time, cold, wet and hot air will gradually invade the human body. If these invasions are not removed in time, it will do great harm to the body, thus leaving the root of the disease. Labor is good, labor creates wealth, and labor also exercises the body. Labor should also pay attention to science. Only scientific labor and scientific exercise can make us stronger and have more wealth. Returning to the topic of sports and turtle rest at the beginning, my personal view is that life lies in sports, and sports rise and move with the sun in time; When the sun goes down, reduce exercise, give priority to rest and conserve internal organs.
Recently, a friend on the Internet asked, "My father, dr. zhang, has been doing farm work all his life. It is said that he often exercises. How did he get sick? " This question actually raises the question of the relationship between exercise and health. Today, Dr. Zhang will tell you about this problem.
Humans realize that exercise is good for health, and the earliest awareness mainly comes from some early European and American studies. At that time, the research was mainly aimed at people in the same working environment, and it was found that the incidence of cardiovascular and cerebrovascular diseases in London, England was lower than that of bus drivers. Compared with telephone operators, the incidence of cardiovascular and cerebrovascular diseases in post offices is relatively low. The main reason for this phenomenon is that the conductor exercises more than the driver, and the postman exercises more than the operator. These studies have solved the human understanding of the relationship between exercise and cardiovascular and cerebrovascular diseases.
Later research found that there are many mechanisms to reduce the incidence of cardiovascular and cerebrovascular diseases through exercise. For example, exercise can reduce triglycerides and low-density lipoprotein, exercise can increase high-density lipoprotein, exercise can improve glucose metabolism, increase insulin sensitivity, exercise can lose weight and so on. These factors can reduce the incidence of cardiovascular and cerebrovascular diseases.
Does it mean that the more exercise, the better, the more exercise, the better? The answer is no, with the gradual deepening of people's understanding of sports, it is found that the incidence of cardiovascular and cerebrovascular diseases has not been further reduced with the increase of exercise. However, sports injuries caused by sports will increase.
In this way, the question comes: how much exercise is the most appropriate?
Generally speaking, the mainstream recommendation at this stage is the suggestion of American sports guide, that is, moderate exercise for 30 minutes every day, five times a week, and 150 minutes a week. High-intensity exercise, it is suggested that 25 minutes a day, three times a week, that is, 75 minutes a week. Having said that, you can answer the questions raised by the opening netizens. Your father has been doing farm work all his life. Why does he still have so many diseases? Because working in the field is a high-intensity exercise, too much farm work may lead to a series of sports injury diseases, such as lumbar disc herniation and arthritis. This is also the reason why many farmers will have many diseases as they grow older.
"My father has been doing farm work all his life and has exercised a lot, but he is sick all over", which is normal! We can understand the subject's feelings for his father, but you may have some misunderstandings about the disease.
First, it is easy to get sick if you exercise less, but it doesn't mean that you won't get sick if you exercise. I wonder if you can understand this logical relationship. Sometimes in the outpatient clinic, there are always some uncles and aunts in their fifties and sixties who complain to me that they are in the front of their circle of friends every day, often taking one or two places, and there are more than 15 thousand without 20 thousand steps. However, how can I get sick! Remember, exercise does not mean that you won't get sick.
Second, doing farm work is not exactly the same as exercising. A friend said that farmers have been doing farm work all their lives, and they should be in good health every day. There is no denying that many people who do farm work are in good health. However, we often meet patients from rural areas. Farmers will also get sick! And doing farm work is really different from exercising! Doing farm work often bends down to pick things up, which is easy to get diseases such as lumbar disc herniation and chronic lumbar muscle strain. So many old farmers will feel uncomfortable all over.
Third, besides exercise, there are many factors that cause diseases. The occurrence and development of diseases are related to many factors, such as genetic inheritance, eating habits, living habits, environmental sanitation and so on. These factors are usually not "fighting alone", but often "gang crimes"! Sometimes patients will ask what causes this disease. Our doctors often answer that the occurrence and development of diseases are the result of the interaction of many factors!
Fourth, the occurrence and development of diseases is a long process, but people often only see the process after clinical manifestations.
Therefore, exercise is often regarded as a way to prevent diseases, that is, pre-clinical prevention. It can't be regarded as a "life-saving straw" for diseases!
This problem has a very serious logical problem. Exercise is not necessarily related to longevity or illness, but only one of the reasons. Besides, you exercise a lot and are sick? It depends on what disease it is. Many diseases have nothing to do with exercise.
If you simply talk about sports and diseases, you will find that the statement that life lies in sports is not 100% accurate. Many professional athletes have left many diseases or sequelae after retirement, and some need lifelong medication or treatment, which may even affect their life span.
Moderate exercise is good for the body, but exercise should master two elements:
First, exercise should be moderate.
Don't exercise excessively and don't sit still for a long time. You should exercise moderately. Your father has been doing farm work all his life. It must be very hard. He may leave some physical diseases, such as chronic muscle strain, joint injury, ligament strain and so on.
Second, exercise should master the correct methods and postures.
When exercising or working, you must master the correct ways and means to minimize the chance of injury. If you don't master the correct method, you will make mistakes in your efforts and easily cause injuries. Even professional athletes, when doing sports, are likely to get hurt, let alone ordinary people.
Moreover, doing farm work is very different from ordinary sports. Doing farm work is inevitable, and long-term work will inevitably leave some problems. Generally speaking, the average life expectancy of farmers is lower than that of urban population.
Labor and fitness are two different things.
Fitness requires the trainer to train in the correct posture, which can be seen from the usual fitness terms, such as straightening back, sinking shoulder straps, contracting shoulder blades and aligning hips, knees and ankles. Fitness is very particular about posture, and everything is to avoid injury. Moreover, bodybuilders usually pay great attention to rest and nutrition supply, so fitness will make the body healthier.
But labor is different. The mode of delivery is single and persistent, which easily leads to muscle and joint strain. In addition, without reasonable rest and nutrition, it will break down from overwork over time.
Life lies in exercise, but you can't overdo it. The human body is like a car. If you drive it frequently and put it in the warehouse, it will break down. However, if it is overloaded, not used according to the operation manual and not maintained regularly, then various problems will also occur.
Therefore, a large amount of exercise is not necessarily good for your health. You can look at those athletes. Basically, their upper bodies were injured and their joints were badly worn. Your father has been doing farm work all his life, which is also heavy manual labor. Farmers are very bitter. They work at sunrise and rest at sunset. Turn your back to the sky and face the loess, bask in the sun, bend over and plant seedlings, carry hundreds of kilograms of grain and step on water to plant seedlings. Working every day, overworking, it is difficult to rest, which is very harmful to muscles and joints.
Environment is also a problem, such as schistosomiasis, which used to have a high infection rate in rural areas in southern China. Many farmers who need to work in rice fields will be infected with this parasite, which will make them weak and cause anemia and other diseases. Then, there is the problem of pollution. In the past few years, the pollution problem was very serious, and many environmental protection policies and facilities were not in place, so the soil and water sources in rural areas were seriously polluted.
In addition, the living conditions in rural areas were relatively poor in the past. Poor nutrition and poor food. Sometimes when I work in the fields, I just grab a few cold meals and eat pickles and bacon. Now it seems to be unhealthy food preserved with high salt. Medical and economic conditions are also poor. A minor illness is delayed, but a serious illness is cured. It is easy to have minor illnesses and serious illnesses, and some fall behind and suffer from this disease for life.
Therefore, a large amount of exercise does not mean that the body must be good, and everything should be moderate.
It is the idea of many people that labor equals exercise. But in fact, labor does not necessarily mean exercise.
For diabetic patients, exercise is one of the "five carriages" to control blood sugar. We will advise patients to exercise regularly, which will help to control blood sugar better. However, some patients often ask some dumbfounding questions. I work, carry water, grow vegetables and do housework every day ... I am busy every day, but why can't I control my blood sugar well? I have no idea that labor is not equal to exercise.
As we all know, farmers are very hard, especially their ancestors, who have come all the way through hardships. Not to mention the labor intensity, it is also accumulated over time, not to mention the harm to the body. In addition, the posture of labor is not scientific at all, such as picking heavy objects, which is very harmful to lumbar vertebrae, intervertebral discs and back muscles. After a long time, many people have left behind the sequelae of low back pain and even hunchback. It is strange that the body is unscientific for many years, and it is not a problem! Therefore, labor and sports are two different things and cannot be equated!
In addition, even if labor can be considered as a part of exercise, exercise is not a "vaccine" and it is impossible to avoid getting sick. Many of those athletes suffer from various diseases. For example, many badminton players and tennis players have joint strain such as shoulders and elbows, many weightlifters have knee joint strain, and many basketball and football players still wear steel plates!
Exercise is also methodical and scientific. We advocate doing what we can, so as not to be tired. Excessive exercise can cause physical fatigue and even muscle damage.
Doing farm work is not exercise, but manual labor. Most manual workers often have improper posture, wrong working rhythm and do not pay attention to rest afterwards.
For many years, the so-called "full illness" is the most straightforward explanation. The ancient Egyptians can sum up the fitness posture of squat and hard pull from their labor, which can explain the importance of posture.
Fitness is to pay attention to posture, rhythm, intensity and recovery. Squat and pull posture is suitable for most work and life. If we can transfer several items involved in fitness to actual work and life, or treat work and life with fitness thinking, we can greatly reduce the probability of injury!
