Getting out of the misunderstanding of labor education practice：＂gamification＂ can’t gain labor interest

　　Labor refers to the activity that people create material wealth and spiritual wealth necessary for their own survival and development through their own hard physical or mental efforts. In the new era, labor education has been picked up again, and schools have gradually begun to jointly carry out labor education practice with society and families. But in reality, labor education is often reduced to a simple task in daily teaching, a simple physical education, skill learning, and even alienated into entertainment, punishment and domestication. This paper holds that the lack of understanding of the connotation of labor and labor education still leads to some misunderstandings in the practice of labor education, such as the "servitude" of cognitive mental work that makes learning and labor oppose each other, the "play" that replaces the real pleasure of labor, and the lack of continuity in labor education, which needs serious reflection based on the connotation of labor education, and has certain practical pertinence, hoping to bring inspiration to readers.

　　1, learning "servitude" put learning and labor in opposition.

　　In recent years, labor education has been promoted to the same position as moral education, intellectual education, physical education and aesthetic education, so some schools have vigorously carried out labor education practice. Some open up schools to build farms and guide students to carry out productive labor practice; Some combine social resources and rely on labor education practice bases to organize students to experience labor. Social practice activities of learning agriculture and learning industry are carried out regularly every year in many places. However, while increasing the opportunities of labor experience, we will find a conventional concept that students’ daily study is not labor. This is really worth reflecting on. Isn’t learning itself labor?

　　In fact, learning itself is also a kind of labor, and learning is cognitive mental labor. Soviet educator Suhomlinski believes that "labor education begins when students sit behind desks and study. Desk is the most complicated machine tool, which makes children, teenagers and teenagers feel that it is shameful to be careless, and laziness and idleness are sad. It is the most difficult thing for students to establish this understanding in education". Learning is a kind of labor that promotes the combination of wisdom and hands’ efforts. In this labor, learning is labor, while knowledge is the result of labor efforts. Under the background of digital labor era, the function of labor gradually turns to the existential function of realizing personal self-worth and obtaining the sense of value and meaning of existence. From this perspective, completing labor outside of learning may not be able to obtain more sense of value and existence than learning process.

　　If learning is labor, why talk about labor education now? Why didn’t the mental work, which occupies the main position in students’ life at present, achieve the purpose of labor education? Why do schools often oppose mental labor and productive labor, and think that too much emphasis on intellectual development leads to insufficient labor experience? This is because the mental work of learning is alienated, and learning has been externalized as "labor".

　　To recognize that learning is externalized as "labor", we need to trace back the essence of learning, a mental labor, and re-examine the current learning process of students. From Marx’s definition of labor, we can see that labor is firstly a process between man and nature. In the process of material exchange with nature, people increasingly realize the common attributes of things and phenomena, and find the regularity and connection between them, while mental labor is expressed in the form of representation, concept and reasoning. Learning this mental work ultimately points to scientific understanding of things, which is also an essential attribute for learning to become mental work. At present, students’ learning has gradually become "externalized labor" pointed out by Marx. Marx said in the Manuscript of Economics and Philosophy in 1844: Labor is an external thing for workers. In labor, he does not affirm himself, but denies himself. Instead of feeling happy, he feels unfortunate. Instead of freely exerting his physical strength and intelligence, he makes himself physically tortured and mentally destroyed. Once the external force stops, he will escape from labor like a plague. This exposition of externalization of labor seems to be just right to describe the study of today’s students. Students’ study is not to scientifically understand reality, but to pursue external material needs. The "tearing books after the college entrance examination" repeatedly exposed by the media reflects the students’ escape from this externally imposed task. Therefore, learning is no longer real labor, and it no longer has the function of liberating physical strength and intelligence.Instead, it becomes "hard labor", so it has little effect on improving students’ labor literacy.

　　2. "Gamification" makes students lose their interest in labor.

　　Corresponding to the fact that learning has become "hard labor", other forms of labor education that are gradually emerging show a trend of "gamification". Some schools carry out interesting and wonderful labor activities to attract students, and some schools integrate labor education into spring outing. On the one hand, this can improve students’ enthusiasm for participating in labor, but on the other hand, we need to pay attention to avoid blurring the difference between labor and games. Labor is the process of externalizing oneself, while game is the process of internalizing reality. The fuzziness of the difference between labor and games is more obvious in the digital age. Digital labor blurs the time-space boundary between entertainment and work, and dispels the traditional antagonistic relationship between play and labor.

　　Labor is a serious process of giving, and the joy of labor lies in creation. This kind of giving also explains the self-externalization of labor. Students devote their physical strength and intelligence to the labor process and gain certain results. The pleasure that students feel in their work is the pleasure of creating things because of self-sacrifice, not fun. There is a difference between labor and games. Games can naturally bring satisfaction to children, but labor itself has no interest in children, so the interest in labor needs to be cultivated and developed consciously. The "gamification" of labor makes many activities look interesting, but there is no labor in essence, and students can’t gain interest in labor. Suhomlinski believes that the interest in labor should be manifested as "they realize that they can act on nature, make plants give fruits, and use tools to process wood or metal into needed shapes". Therefore, in the practice of labor education, we need to judge whether the interest in the labor process comes from giving and creating, or is interfered by other factors such as gamification.

　　The contribution in the process of labor can cultivate positive labor values and make students love the working people and respect the fruits of labor. At the end of the 19th century, a "new" school appeared in France to train people engaged in "advanced knowledge occupations". In this school, students treat manual labor just like games and sports, because they don’t have to live by manual labor in the future. Although this school is located in the countryside, the students are far away from farmers’ lives. Although they are also working, they can’t really understand and study various social relations. Rousseau believes that only by taking part in labor in person and understanding all its complexity and arduousness according to experience can students judge the social significance of a production department in the future. Therefore, if we don’t regard labor as a serious process, we can’t cultivate our feelings for the working people, and we can’t cultivate our appreciation for the obtained survival materials.

　　3. Labor education stays in experience and ignores daily self-service labor.

　　At present, the labor practice of studying industry and agriculture in some areas is vigorously carried out, and an institutionalized labor experience system is gradually formed based on the construction of learning industry and agriculture bases. However, the persistence of these activities is worthy of attention. Most schools spend one week each semester leading students to experience labor, but they only stay in the experience once each semester, and there is a lack of cohesion between the activities, which is easy to make the labor experience become a casual entertainment. What’s more, some schools organize students to pull weeds in wasteland, and students regard pulling weeds as a kind of hard labor. This kind of labor experience of "working without teaching" deepens students’ rejection of manual labor. Therefore, the experience of labor must be complete, so that students can see the results of labor and feel satisfied with the achievements they have made through their own labor. If we just stop at pulling weeds without letting students experience the significance of pulling weeds for the growth of saplings, it will be difficult for this labor experience to play its due role. To lead students to plant wheat seedlings, we should let them see the process of wheat seedlings growing, heading and harvesting, and even let them see the process of wheat grains turning into food. At this time, the sense of pleasure comes not only from obtaining external products, but also from experiencing the sense of value and existence of labor.

　　In fact, daily self-service labor is just the way to implement the principle of continuity of labor education. However, these are often ignored in schools and families. Schools spend time and energy to organize off-campus labor practice, but at noon, catering staff bring students lunch to the classroom, "depriving" students of the opportunity to experience self-service. The relationship between man and self is at the core of the three attributes of man, which also means that students’ self-service labor plays a vital role in students’ all-round development. Self-service labor can be regarded as the beginning of labor education. No matter what kind of productive labor he is engaged in in in the future, self-service will become his obligation and habit, and it is also the habit of cultivating people to observe discipline, meet their personal needs by doing it themselves, and form the habit of respecting others. When students get food effortlessly, it is difficult to ask them to respect food and labor.

　　4. Strategies and suggestions for getting out of the misunderstanding of labor education practice.

　　"If there is labor, there may not be education". Labor needs to satisfy three relational attributes, namely, man and self, man and nature, and man and society. The basic contents of labor are: self-service labor, productive labor and social welfare labor. Labor education is a practical activity based on physical labor and material production labor, exploratory innovation labor and artistic aesthetic labor, which is manifested in independent life in family life, practice and hands-on operation in study, public welfare activities in society and various professional labor. Therefore, the strategy to get out of the misunderstanding of labor education practice is to balance people’s different forms of labor demand through diversification.

　　First of all, set up a cohesive and comprehensive labor education course. Dewey once said in The Waste of Education that all aspects and stages of education lack the necessary connection and cohesion with each other, which leads to conflicts and even negative effects. Similarly, in order to avoid the waste of education caused by labor education staying at the experience level, the labor education curriculum needs to pay attention to the cohesion of labor content and skills, which is reflected in the cohesion of curriculum content and the cohesion of education system. In terms of course content, it is necessary to set up labor courses that echo and connect properly according to the needs and characteristics of students of different classes and grades. In the education system, it is necessary to consolidate the skills and concepts of labor education through the cooperation between family and society. Schools can encourage students to find service jobs at home, take the initiative to participate in housework, and learn some labor skills. In addition, the content of labor curriculum also needs to take into account three basic labor education contents, namely, self-service labor, productive labor and social welfare labor.

　　Secondly, change the concept of labor education of parents and educators, so that parents and educators can establish labor education awareness. The promotion of the cooperative mechanism between labor educators and schools puts forward higher requirements for teachers and parents’ awareness of labor education. For example, some schools will arrange "homework". If teachers and parents can’t pay attention to it, the effect will be greatly reduced. In order to avoid staying in the curriculum, labor education needs to enhance the awareness of teachers and parents. On the one hand, it is necessary to interpret the connotation, function and significance of labor education in combination with the development of the new era. On the other hand, it is necessary to change the concept of labor education through necessary education and training, so that they can voluntarily carry out and cooperate with the development of labor education activities.

　　Finally, actively develop creative forms of labor and promote the combination of physical strength and brain power. Creative labor enables students to use the power of wisdom in physical labor, realize the unity of "internal thinking" and "external doing", and thus experience the happiness of labor. Wang Shaoliang, a scholar, believes that the labor values of contemporary teenagers have changed from "labor glory" to "labor happiness", that is, from "a kind of praise obtained from the outside through labor achievements" to "confirmation and affirmation of an essential force from their own labor achievements". Therefore, the development of school labor activities can not stay in simple physical labor, but needs to develop challenging creative labor that can show students’ physical and mental potential. Suhomlinski’s "creative labor theory" also points out that the content of labor education should be enriched with enough knowledge, abundant wisdom and refined talents.

Break dancing has become an official Olympic event, and the formation of the national team has begun to select talents.

　　　　　　 CCTV News:Together with skateboarding, rock climbing and surfing, break dancing has become an official event of the Olympic Games. A few days ago, when IOC President thomas bach announced this decision, it really caused quite a stir. When it comes to break dancing, friends over 40 must have special feelings. In the 1970s and 1980s, break dancing became popular in China. No matter the streets and alleys, as long as the dynamic music rang, there were young people with explosive heads, bell bottoms and open-fingered leather gloves, while stepping on the spacewalk, cleaning the glass with their bare hands and dancing with each other, showing their youthful vitality. In many variety shows at present, break dancing is even more cool, and the limelight is the same.

　　　　　　 [After all] What kind of dance is "Olympic" break dance?

　　　　　　 Break dancing, English name Breaking, is sometimes translated as "floor dancing" because of its classic movements on the ground. From leading the trend of street culture to becoming an official Olympic event, what kind of dance is break dancing?

one

　　　　　　 Hold the ground with one hand, exert your strength instantly, and your body will fly and spin rapidly. The young man who danced like a tornado and looked wild and free was 20-year-old Shang Xiaoyu. As the only break dancer in China, he played in the 2018 Youth Olympic Games, competing with the world’s top players, and finally broke into the top eight.

　　　　　　 Break dancing originated from American hip-hop culture in the 1960s and 1970s, and it is a kind of generalized hip-hop. Its symbolic action is that dancers support their bodies with their hands and heads to do rapid rotation and tumbling on the ground, which has the elements of sports competition since its birth, and street cheers are the basis for judging the success or failure of fighting dancing. In 1987, the American film "Break Dance" was released in China, and it was all the rage to take a "spacewalk" with a tape recorder on your shoulder or "clean the glass" in the air. However, these movements are not break dancing.

　　　　　　 Su Jie, Secretary-General of China Sports Dance Federation: "The break dance in the movie is the predecessor of breaking now."

　　　　　　 According to experts, the most obvious feature of break dancing is that athletes are no longer satisfied with expressing music with their bodies, but pursue to explore the limits of the human body in rhythm, and Thomas and handstand rotation have become symbolic movements.

　　　　　　 [Question in the end] There are various forms of street dance. Why can break dance "enter the Olympics"?

　　　　　　 As a competition, break dancing made its debut at the Youth Olympic Games in Buenos Aires in 2018, which also played an important role in promoting its official entry into the Olympics. There are many forms of street dance, so why can break dance "enter the Olympics"?

　　　　　　 Su Jie, Secretary-General of China Sports Dance Federation, said: "One of the strong characteristics of break dancing is that it is very competitive. The form of competition generally appears in the form of fighting dance, that is, one-on-one PK, and the criteria for judging are relatively clear, so it can be the official event of the Olympic Games first."

　　　　　　 In China, break dancing has also become the only dance in the street dance competition of the 2nd Youth Games held in 2019, and China break dancing has officially entered the preparation stage for the 2024 Paris Olympic Games.

　　　　　　 Experts believe that dance presentation, music understanding, dance culture interpretation and innovation may be the scoring points of break dancing after entering the Olympics.

　　　　　　 How to form a national break dance team?

　　　　　　 The reporter learned from the China Sports Dance Federation that the formation of the national break dance team for the 2024 Paris Olympic Games has started, and talent selection has begun. At the same time, the preparation and selection plan has also entered the revision stage and is expected to be announced to the public in the first half of 2021. How to form the national team of break dancing? In particular, everyone is very concerned about whether those stars who are good at break dancing will also have the opportunity to enter the national team.

　　　　　　 Su Jie, secretary-general of China Sports Dance Federation, said: "We will decide who can be selected into our large talent pool by comprehensive standards, not whether he is an performing star or a person engaged in a certain profession. We are based on sports performance."

　　　　　　 According to reports, it takes two steps to form a national team of break dancing. First, a talent pool is established by extensively selecting talents in the whole society, and then the national team candidates are finally determined through a competitive selection mechanism.

　　　　　　 Su Jie, Secretary General of China Sports Dance Federation: "Now the selection method has entered the revision stage, and then it will be reported to the relevant departments for review, and finally we will announce it to the whole society. The announcement time is probably before the first half of next year. "

　　　　　　 [After all] Is everyone suitable for break dancing?

　　　　　　 The door of the national break dance team is open to the whole society. Are you also moved? It is estimated that many parents will be busy letting their children practice again. Is it suitable for everyone to break dance? What should we pay attention to when engaging in this sport?

　　　　　　 In the face of zero-based reporters, Shang Xiaoyu only selected a few simple warm-up professors, but the reporters still found it difficult to control.

　　　　　　 Wang Hong, a professor at Beijing Sport University and a member of the "Source News" expert database of the China Association for Science and Technology, said: "Many movements really violate some concepts of traditional sports training, and the risk of injury is great. Some movements of flexibility and explosive force may be harmful to a child who does not grow well, to the development of his bones or to his ligaments, for example, to the lumbar spine. If children and young people want to do this kind of action, you must first practice basic physical fitness and special physical fitness before you can rise to the level of technical training. "

　　　　　　 Shang Xiaoyu, the only player of the China team in the break dance event of the 2018 Youth Olympic Games, said: "Don’t always focus on these rotations and difficult movements. In fact, breaking is more interesting in its dance."

　　　　　　 [After all] Although break dancing is cool, can everyone try it?

　　　　　　 Finally, I would like to remind you that although break dancing is cool, its difficult movements such as tumbling, handstand, head turning and Thomas require very high strength, flexibility and coordination. Don’t try rashly if you don’t have a certain physical quality. Especially parents and friends, all want to build a handsome baby, but break dancing is fierce and difficult, and it is not suitable for children who are too young to learn, so as not to get hurt.

The latest report in the United States shows that the quality of Boeing 737Max aircraft is serious, and 33 of 89 audits failed.

(Observer Network News) According to the disclosure on March 11th, local time in The New York Times, USA, the FAA found that Boeing "has many problems in quality control" after six weeks of audit. Among all 89 audits, Boeing passed 56, 33 failed, accounting for more than 37%, and 97 possible irregularities were found.

The quality problem is serious, and the qualified rate of fuselage audit is less than 50%

According to the inspection report of Federal Aviation Administration (FAA) cited by The New York Times, there are dozens of problems in the manufacturing process of Boeing 737Max aircraft manufacturers and their main suppliers.

After the Mense crash of Alaska Airlines Boeing 737MAX in January, the FAA began to investigate this type of aircraft. The survey results show that 56 of 89 audit subjects passed the audit, 33 failed the audit, and the failure rate exceeded 37%. During the audit, there were 97 suspected violations.

In the investigation of 737Max fuselage contractor Spirit AeroSystems, the report showed that seven audits were unqualified, which was unreasonable by more than 50%. It is mentioned in the report that the personnel of the air safety agency have witnessed the mechanic of Spirit company using the hotel room card to check the plane’s Mense. In addition, the FAA personnel also saw the mechanic of Spirit company smearing soap liquid on the door plug as a "lubricant" during fitting, and then cleaning Mense with a wet cheese cloth.

In an audit of Mense components by Spirit Company, the investigators found five problems, one of which was that "no evidence was provided to prove that the minor design changes of the aircraft had been approved by the FAA". Another audit that Spirit failed involved the installation of Boeing 737Max in Mense. In this audit, investigators expressed their concern about the Spirit technicians who performed this work because the company "failed to clearly understand the knowledge needed to implement this process".

Other audits that Spirit failed include those involving cargo doors and the installation of cockpit windows. In this regard, Spirit spokesman Joe Buccino said that the company is "reviewing all identified non-compliance behaviors to correct them".

In the audit of Boeing, the auditors found that many problems of Boeing were not following the "approved manufacturing processes, procedures or instructions", and other problems involved the quality control of Boeing aircraft.

The FAA also rated Boeing employees’ understanding of the quality control process. In the survey, they interviewed six company engineers and graded their answers, with an overall average score of only 58%.

According to the report, the FAA has deployed as many as 20 investigators in Boeing and about 6 investigators in Spirit.

It is worth noting that Spirit AeroSystems was spun off from Boeing Commercial Aircraft Company in 2005. Boeing said this month that it is in talks to acquire Spirit.

In March, there were four vicious accidents, and Boeing whistleblowers committed suicide.

Recently, Boeing’s security issues have once again attracted attention from all walks of life.

Following the fall of Boeing 737Max 9 Mense in January, several people on board were injured, the engine of Boeing 747-8 cargo plane caught fire over Miami, and the tire of Boeing 757 fell off. Since March, Boeing has had four consecutive vicious accidents. At the beginning of the month, there were three accidents including engine fire, tire falling off and skidding off the runway.

On the 11th local time, a Boeing 787-9 caused a "strong vibration" due to "technical problems" during the flight. At least 50 people were injured in the vibration, and then the plane landed at Auckland airport.

The New Zealand Traffic Accident Investigation Committee said on Tuesday that it was detaining the cockpit voice recorder and flight data recorder (black box) of the Boeing 787-9 plane that injured 50 people on the 11th. The black box will provide more information about the flight trajectory and communication between pilots.

On March 9, local time, the government of South Carolina confirmed that John Barnett, a 62-year-old former employee of Boeing, who publicly questioned the problems in Boeing’s production line, was found dead in the car.

In 2010, he began to work as a quality manager at the Boeing factory in North Charleston, and retired in 2017. In 2019, barnett reported that the overworked employees of his Boeing factory in South Carolina deliberately installed substandard parts on the aircraft on the production line. A few days before his death, the old employee who had worked for Boeing for 32 years was still busy with his lawsuit against Boeing. He was found dead because he failed to provide testimony on the 9th.

Lawyer barnett used "alleged" to describe his client’s statement of "shooting himself".

Put away your competitive heart when running.

Unless you are interested in becoming a professional runner, for most amateur runners, running is not a competition in the arena. You have to figure out what you are running for.

I think some runners blindly follow the trend when they see other people’s achievements, so they can’t resist a competitive heart. All I can think about is the amount of running and pace. In the end, even if I ran out of good grades, I also ran out of injuries. What’s the point?

For amateur runners, the word "stability" is the most important, and jogging is the truth. Be a little timid, it doesn’t matter! Run slowly, run less, and leave if you can’t run. It’s really nothing. It is even more important to achieve the "three noes": no running when you are sick, no running after drinking, and no running after staying up late.What do you think? Let’s talk in the comments section.

These actions hurt your knees more than running, and some people do them every day!

now

Exercise has become a "compulsory course" for many people every day.

And in many sports,

Running is deeply loved by many people.

Recently, a circle friend sent for help and said

There are all kinds of sayings about running on the Internet.

The most popular saying is that running will hurt your knees.

Is this really the case?

Zhao min

Peking University Third Hospital

Deputy chief physician of orthopedics

Does running really hurt your knees?

Improper running posture or excessive load is the most likely to damage the knee joint.

Incorrect running method exceeds the load of knee joint, which will easily lead to "running knee", which is a chronic overwork.

No matter ordinary people or athletes, they may encounter the problem of knee joint injury in sports, but the "running knee" only exists in the situation of knee overuse, which is related to personal sports and physical fitness.

Both sitting without running and high-intensity running can cause joint problems, and the prevalence rate is the lowest among people who run at leisure, so proper running is beneficial to joint health for ordinary people (non-athletes) as a whole.

Unscientific exercise is an important cause of knee injury. If you don’t warm up before running, it will have a huge impact on the meniscus and even cause comminuted fracture of the patella.

Incorrect running posture, too long exercise time, too high frequency and different physical qualities of individuals are all factors that cause knee joint injury.

Therefore, incorrect running methods or excessive use of knees will lead to knee injury, but you can’t stop exercising completely.

Action points:

Warm up for 5 ~ 10 minutes before jogging, and the duration of pure running is 30 ~ 60 minutes every day, so don’t care too much about the distance;

The body leans forward slightly, the arm swings naturally, and the forefoot touches the ground;

Keep the speed "breathing, heartbeat is slightly faster but you can talk normally";

Plastic ground, asphalt road, etc. are selected for the site, and cement ground is not recommended.

These movements hurt your knees the most.

Step 1 sit still for a long time

An internationally authoritative study once pointed out that the incidence of arthritis in fitness runners is 3.5%; For sedentary people, the incidence of arthritis is as high as 10.2%! Long-term sedentary articular cartilage will gradually lose nutrition and "starve to death". Therefore, proper exercise can prolong the life of the knee. But the premise is to master scientific methods and avoid unnecessary damage.

Step 2 climb mountains and stairs

Old people, overweight people and people with knee injuries had better crawl less. Don’t insist on climbing if your knees are uncomfortable.

When going up the mountain (stairs), the wrong posture can easily hurt the knee, and the knee will bear about three times its own weight.

When going down the mountain (stairs), the knee will not only bear the impact of the ground, but also increase the wear of the knee.

Therefore, it is not recommended to climb mountains and buildings as daily exercise.

Tip: There is a knee injury. When going upstairs, the good leg goes first, and when going downstairs, the bad leg goes first.

Step 3 jump rope

The risk of skipping rope to knee joint is mainly related to the venue.

Generally, the concrete floor downstairs in a residential area can’t provide an effective buffer for the impact force when skipping rope falls to the ground, and it is easy to hurt the knee for a long time.

Key points of skipping rope:

Choose plastic floor or cement floor to pave plastic mat;

When jumping, keep your feet close to avoid bending your knees greatly;

The take-off height is 2 ~ 4 cm to ensure that the skipping rope just passes through the soles of the feet;

Shake the rope with wrist strength and keep the big arm close to the trunk.

4. Riding a bike in the wrong posture

If you ride too hard, or take some wrong riding posture habits, it will also have certain health risks to your knees.

Action points:

The height of the seat is adjusted to: when the foot steps on the lowest position, the knee joint slightly bends about 170;

Hold your head high while riding, keeping your knees and toes facing forward;

Keep riding at a constant speed, and don’t suddenly increase the speed by force;

Exert force on the thigh and step on the pedal with the first third of the sole of your foot.

5. I don’t have exercise habits at ordinary times, and I suddenly run away.

For people who don’t have any exercise habits at ordinary times and sit for a long time every day, leg muscle strength is usually insufficient, and sudden long-term walking is easy to cause instability of knee joint position.

Suggestion: Try to avoid striding, don’t stretch your front legs too far, avoid tightening your legs or knees and step forward, so that your body can walk naturally, comfortably and moderately.

Step 6 sit cross-legged

When sitting cross-legged, the knee joint is in a state of flexion. Under the action of gravity, it will bear the sinking force, resulting in uneven stress on the inside and outside. Over time, the knee joint is also prone to deformation.

Suggestion: when you can’t help sitting cross-legged, bend only one leg at a time, try to be natural and comfortable, and don’t force your feet down, which can reduce the damage to your knees to some extent.

Step 7 squat for a long time

When the squatting posture is greater than 90 degrees, the compression of the medial knee joint will become larger, resulting in the wear of the medial patella.

Suggestion: Try to control the toilet time in squatting position within 3 minutes.

These symptoms appear in the knee joint.

May have suggested joint damage.

If you can’t remember your knee joint at all, first of all, it shows that it is healthy. When you start to pay attention to your knee joint, it may indicate that there are some problems with it.

Then there are probably two kinds of problems that often appear in our knee joint:

1. it hurts

This is the most common situation. Suddenly, I feel pain in my knee. The pain varies from light to heavy. Another is its position. If you touch your left knee with your palm, buckle the patella above your knee with the palm of your hand. After buckling it, when your thumb naturally droops, you can touch a gap. This is the gap on the inside of the knee. If this position is painful, you should be careful about meniscus or osteoarthritis. If this position is further up.

Step 2 make a noise

Sometimes there will be some noise in the knee joint, a crisp snap, without pain, which may be some physiological snap, such as synovial hyperplasia. If you have degenerative osteoarthropathy and arthritis, its noise is very characteristic, just like when you hold a handful of snow in winter, the snowball makes a creaking sound. This feeling of holding snow is a very typical manifestation of osteoarthritis, called bone rubbing sound.

You can protect your knees by sitting and lifting your legs.

The first method:

When the leg bends to 90 degrees, the calf and thigh are basically in a vertical state. At this time, you can slowly extend the leg from 90-degree knee flexion to straightness, and pause for 5~10 seconds. You should feel the muscles in front of the thigh, especially the muscles in the inner thigh, exerting force and straining, and then slowly relax it to the knee flexion position. This is the first time.

We can repeat this cycle for 20 ~ 30 times, and this is a group, and we can do 2 ~ 3 groups every day.

Note: If you feel tired the next day, it means that this intensity exercise is appropriate. If you feel relaxed after exercise, you may need to correct your movements or increase your strength and frequency.

The second method:

You can step on something under your feet. At this time, the angle of bending your knees is less than 90 degrees. Slowly straighten it, straighten it to the position of 0 degrees, keep it for 5~10 seconds, and do reciprocating training.

Leg-lifting in sitting position is suitable for both sick patients and healthy people. It is a very basic training, so everyone should develop such a habit, and its application scenario is very wide. You can do such a training whether you are in the office or on a business trip.

Note: If the joint is in the inflammatory stage of redness, swelling, heat and pain, you should rest instead of doing any strength training, even if it is mild, and you should wait until the inflammation is relieved, the symptoms are relieved, or even disappear before starting strength training.

These symptoms appeared in the knee joint.

May have suggested joint damage.

If you can’t remember your knee joint at all, first of all, it shows that it is healthy. When you start to pay attention to your knee joint, it may indicate that there are some problems with it.

Then there are probably two kinds of problems that often appear in our knee joint:

1. it hurts

This is the most common situation. Suddenly, I feel that my knee begins to hurt. The pain varies from light to heavy, and the other is its position. If you touch your left knee with your palm, use the palm of your hand to buckle the patella above your knee. After buckling it, when the thumb naturally droops, you can touch a gap. This is the gap inside the knee joint. If this position hurts, you really have to be careful. For example, there will be some problems like meniscus or osteoarthritis. If this position is higher or lower than the knee joint, it may come from the ligament, so we judge it according to the painful part.

Step 2 make a noise

You can protect your knees by sitting and lifting your legs.

The first method:

When the leg bends to 90 degrees, the calf and thigh are basically in a vertical state. At this time, you can slowly extend the leg from the 90-degree knee bend to the straight, and pause for 5~10 seconds. You should feel the muscles in front of the thigh, especially the muscles in the inner thigh, exerting force and tightening, and then slowly relax it to the knee bend position. This is a time.

We can repeat this cycle for 20 ~ 30 times, and this is a group, and we can do 2 ~ 3 groups every day.

Note: If you feel tired the next day, it means that this intensity exercise is appropriate. If you feel relaxed after exercise, you may need to correct your actions or increase your strength and frequency.

The second method:

You can step on a whole box of cans under your feet. At this time, the angle of bending your knees is less than 90 degrees. Slowly straighten it to the position of 0 degrees, keep it for 5~10 seconds, and do reciprocating training.

Six things to prolong the service life of the knee

Knee joint should be used sparingly, and only by protecting it can its service life be prolonged;

Step 1 control your weight

Patients with knee arthritis caused by overweight account for a large proportion of the sick population. Losing weight can greatly reduce the burden on weight-bearing joints and reduce wear and tear.

2. Exercise with restraint

The healthiest exercise program for joints is: 30 minutes of moderate-intensity physical exercise every day, no less than 5 days a week.

Warm up before exercise, exercise and stretch properly. If you do strenuous exercise, warm-up time should not be less than 10 minutes.

When swimming, the body is basically parallel to the water surface, and the knee joint is basically free of load, so it is best for the knee joint. Freestyle and backstroke are more recommended to protect the knee joint.

3. Pay attention to joint warmth

Avoid cold and damp knees, and wear knee pads if necessary.

Step 4 supplement calcium

Especially women over 40. When osteoporosis occurs, joints are prone to illness.

5. Shoes should be suitable

Whether walking or other sports, you should choose a pair of suitable shoes. Sports shoes with elasticity, slightly thicker soles and slightly thicker heels are the best for joints.

6. Avoid continuously exerting force on joints.

Try to reduce squatting as much as possible. If you need to squat frequently, you’d better sit in a low position, such as sitting on a small bench. When sitting and standing for a long time, you should always change your posture to prevent your knee from being fixed in one posture and being strained.

Note: Don’t exercise easily when your knee hurts. If there is injury or pain in the knee, you should see a doctor in time and standardize the treatment. Consult a doctor and make a suitable recovery exercise plan according to your own situation and illness.

Knee pad tips

1. Improper running posture or excessive load is the most likely to damage the knee joint.

2. These actions hurt your knees the most: sedentary, skipping rope, climbing mountains and stairs in the wrong posture, riding a bicycle in the wrong posture, having no exercise habits at ordinary times, suddenly running away, sitting cross-legged and squatting for a long time.

3. These symptoms of knee joint may have indicated joint damage:

Pain: the gap inside the knee joint hurts, and there may be problems with meniscus or osteoarthritis;

Sound: Osteoarthrosis and arthritis will cause bone rubbing sound.

4. Sitting leg lifting is a basic training suitable for both sick patients and healthy people.

5. Extend the service life of the knee: control the weight, exercise with restraint, pay attention to joint warmth, supplement calcium, fit shoes, and avoid exerting force on joints continuously.

Mango TV Transformation, ＂Under the Sun＂ catch me if you can, both the editor and the director are excellent!

According to the past habits, most of the dramas broadcast by Mango TV can’t escape the youth idols and sweet pets, but the opening year of 2021 is really a big surprise. The New Year’s drama chosen by Mango TV is actually Under the Sunshine produced by Bona, a big play in catch me if you can, knowing that the villain is there, but for various reasons, he can’t be brought to justice immediately. You must also make a pretence with him and deal with dozens of criminal investigation dramas!

From the first two episodes, "Under the Sun" shows a sense of suspense and tension that is not lost to this year’s hot and foggy theater. After being hijacked by gangsters halfway, the female university teacher escaped calmly and tactfully, and found that the murderer at that time changed her identity and reappeared in her life seven months later. The old policeman, who has been suspicious of the case and carefully pursued it, was victimized by the gangster’s design step by step, but he secretly left a chess piece and ambushed the murderer. The killers with high IQ and high face value play with their prey in their hands like cats, as if they don’t mind that their minions also have deadly abilities!

Not only is the story tightly woven and full of unexpected suspense, but it is also excellent in actor performance. First of all, I have to talk about Mr. Wang Jinsong. Although he has been off the production line in the third episode, he has set a benchmark for all the actors in these two episodes. Moreover, Chen Jinyan, the old policeman he played this time, is completely different from the role he interpreted before. Besides the justice of the police, he also has a special human touch, especially for Xiaowu, played by Liu Kai, who used his own dead church as a street punk to mix responsibility and justice, which also made the story have a longer-term development.

Another surprise is Peng Guanying. I have always paid close attention to this actor, not only because of his outstanding appearance and good acting skills, but also because he can often give people a reasonable role and some unexpected feelings. For example, in The Longest Day In Chang’an, the hypocritical son, a few scenes can be impressive. This time, he played the roles of Feng Xiaosheng and Shen Shijie respectively. When he first appeared, several side shots were full of ferocity. After that, the chic and arrogance of staying at the group headquarters was still a true performance. When I arrived, I played with Ke Yingshi’s abnormal eyes, which can be regarded as the most creepy scenes at the end of 2020. However, in the face of martial arts, people have to believe that people are complex and fickle animals. Such polarized emotions and performances make Peng Guanying play incisively and vividly in a short series. I believe that after the broadcast of Under the Sun, he will soon become one of the most frightening characters on the screen after An Jiahe!

On the other hand, "Under the Sun" has not forgotten the theme of guiding people to be good in film and television works while making great suspense and puzzles of human nature. From the beginning to the end, there were old policeman Chen Jinyan, victim Ke Ying and bystander Xiaowu who spared no effort to work for justice and vowed to wipe out criminal gangs and murderers. Even in the face of life and death threats and various threats from family members and relatives, they never gave up their persistence, but became more determined and more skillful in fighting criminals and crimes.

2021 is coming soon. At this time, watch "Under the Sun" on Mango TV, feel catch me if you can, who is frightening and inspiring, and understand what "justice may be late, but it will never be late!"

Swimming an hour to eliminate 1000 calories？ Why are you getting fatter and fatter？

　　Many people say that swimming is one of the best exercises to lose weight. Swimming for one hour can eliminate 1000 calories, which is almost the sum of the calories a person needs in a day.

　　Does this mean that as long as you swim for an hour, the calories you eat in a day will disappear? Can it really consume that much? Then why do some people get fatter after swimming?

　　How many calories can swimming consume?

　　In fact, swimming consumes 1000 calories per hour, which is not accurate and comprehensive. The amount of heat consumed per hour varies greatly with different intensities of swimming.

　　According to the data of "Nutrition and Dietary Guidelines for China Residents (2016)", a 66 kg male, with an average freestyle/backstroke of 30 minutes, consumes 264 kilocalories; Breaststroke for 30 minutes consumes 330 kilocalories; Butterfly swimming consumes the most calories, which is 363 kilocalories.

　　In contrast, a 56 kg woman spends an average of 30 minutes in freestyle/backstroke, consuming 224.1 kilocalories; Breaststroke for 30 minutes consumes 279.9 kilocalories; The maximum calorie consumption of butterfly stroke is 308.1 kilocalories.

　　Although you don’t exercise for an hour and consume 1000 calories, it is undeniable that swimming does burn fat. In contrast, a 66 kg man jogs for 30 minutes on average and consumes 231 kilocalories. A 56 kg woman jogs for 30 minutes on average, and consumes 195.9 kilocalories. In addition, another advantage of swimming is that there is no damage to the knees.

　　Why did you get fat after swimming?

　　But why do some people get fatter and fatter after swimming? First of all, it has much to do with how much you eat. Dr. Wu Xi, an associate professor in the Department of Endocrinology and Metabolic Diseases, Huashan Hospital affiliated to Fudan University, pointed out that losing weight actually creates a calorie gap and consumes a lot of calories, but it is impossible to lose weight by taking more. People usually feel hungry after swimming and want to eat food with high fat content. Some people feel that they consume so many calories, and when they get home, they can eat some high-calorie foods with peace of mind, not only will they not lose weight, but they will also get fatter and fatter. Sometimes, after swimming for an hour, a bottle of coke will offset it.

　　You should still eat some foods with high fiber and low calorie before and after swimming, including bananas and tomatoes. It is not good to eat when you are hungry, which is easy to cause overeating.

　　Dr. Wu Xi pointed out that exercise to lose weight should be a long-term and persistent lifestyle, and weight loss should also be a gentle process. As long as you persist in sports with enough intensity for more than half an hour every day and keep your heart rate at 120-150 times per minute, you will eventually see results.

　　Of course, there is another possibility. If you find that you gain weight after an exercise, it may be caused by drinking more water after exercise. If you gain weight after a period of exercise, it may be that the proportion of muscle has increased and the proportion of fat has decreased. Because of the high density of muscles, muscles with the same volume are much heavier than fat, so despite the weight recovery, the weight loss effect has actually been achieved, and the body will look more compact.

　　"Of course, in addition to aerobic training, resistance exercise is also very important for improving basic metabolism and body shaping; Muscle training first, then aerobic exercise such as swimming and running can also prevent joint injury. Every week, 1-2 times, 30-45 minutes of resistance exercise, or HIIT exercise program (high-intensity interval training), which can effectively maintain and increase muscles. " Dr. Wu Wei said.

　　We should pay attention to these problems when swimming safely.

　　Summer is the season of rapid growth of various pathogenic microorganisms and high incidence of various ocular surface diseases, and the average infection rate is twice as high as that in winter, especially in public swimming pools. If the disinfection measures are not strict, it will easily lead to the spread of pinkeye (infectious conjunctivitis). So how to prevent it? Can I swim during my period? The reporter interviewed relevant experts.

　　Dr. Hong Jiaxu, an attending ophthalmologist at the Eye, Otolaryngology Hospital affiliated to Fudan University and a postdoctoral fellow at Harvard Medical School, suggested that you should choose a regular swimming place to ensure the water quality and wear goggles before entering the water. Regular swimming pools will sterilize the water source, but once one or two patients with pink eye enter the swimming pool, they may still infect other people.

　　Pink eye disease is mainly transmitted through contact, such as towels, face plates, eye drops, coins, keyboards, door handles, faucets and so on. After touching things with germs, rubbing your eyes with dirty hands is more likely to infect bacteria. Therefore, the management of swimming pools should also strengthen supervision, prevent patients with pink eye from swimming, and strengthen the sterilization of water sources. In addition, patients with pink eye should also be conscious, swimming may aggravate their condition, so they should not go swimming in public swimming pools again. In addition, everyone should also pay attention to personal hygiene, wash their hands frequently, and don’t cross-use daily necessities such as towels.

　　Huang Weihong, deputy director of obstetrics and gynecology department of Shanghai Zhongshan Hospital, pointed out that some women think that they can get into the water safely by using tampons or moon cups during menstruation, but this method is not desirable. Women’s vagina is connected with the outside world, which provides the possibility for bacterial infection. Moreover, the cervix of the uterus is relatively dilated during menstruation, and the blood flowing out of the uterus during menstruation itself is a good culture medium for the reproduction of germs. After the tampon is soaked in water, germs can easily enter the body, causing reproductive system infection.

　　"Of course, if you enjoy the environment very much when traveling, and women are at the end of their menstrual period, if you really want to go into the water, it is not bad to use tampons or menstrual cups, but swimming during menstruation for a long time will increase the chance of infection, which is definitely not recommended."

　　Dr. Huang Weihong said, "Female swimming during menstruation is prone to reproductive system infection or menstrual disorder, and it will not be cured for a long time."

　　Dr. Huang Weihong warned that if you swim in unsanitary water, dirty water can enter the vagina, and germs can take the opportunity to cause various diseases. Although the water in the swimming pool is disinfected circularly, it is impossible to be sterile, and there is no guarantee if it is not disinfected thoroughly in some places. There are many swimmers with tinea corporis, tinea pedis, trachoma, fungal vaginitis or trichomonal vaginitis, and even patients with gonorrhea and condyloma acuminatum. They bring pathogens into the pool water and easily infect healthy swimmers.
