Running is a very effective exercise to lose weight, and it is the first choice for the majority of dieters. However, due to the lack of relevant sports knowledge, many people will encounter many problems when they lose weight by running.

For example, I think that the more I run, the more fat I consume, so I am desperate to run wildly, and I can’t wait to run tens of thousands of kilometers in one day to consume all the body fat.

The more you run, the more fat you consume. To some extent, this view is correct. But the problem is that the human body has its limits. A body with an excessive body fat rate cannot run forever. Even if you think you can keep running, your body is gradually collapsing.

Every time you run, there is actually a limit value. When you are about to reach the limit, your body will show some signals as a warning. If you run faster, when you reach the limit, your running speed will drop uncontrollably. No matter how fast you want to run, you can’t take a bigger step. This is because there is little muscle glycogen left in your body, and the proportion of fat consumption has reached the maximum, but the energy provided by fat consumption is actually not much, which is not enough to support your running faster. This is a very important signal that your body can’t run much longer.

If the brain is still trying to run at this time, it can only decompose the protein in the muscle to provide energy as a supplement, which is very harmful to the muscle tissue and the root cause of running off the muscle. While consuming protein’s function, the brain will secrete endorphins, which is a natural analgesic and can relieve the pain of reaching the limit. At this time, you will suddenly change from a painful running state to a light-footed one. This is actually a second warning, but many people mistakenly think that running is getting better and better, so they will run more and expand the harm caused by excessive running.

After the muscle mass caused by long-term excessive running decreases, the basal metabolic rate of the body will also decrease, and the speed of fat loss will slow down. This is really "going too far".

In addition, excessive running in desperate pursuit of running distance will also lead to terrible consequences such as joint wear, muscle strain and even acute renal failure.

The process of losing weight is very long, and there is no shortcut at all. If you run moderately and develop running habits slowly, the body fat rate will gradually decrease unconsciously.

I am a person who can hardly exercise. For me, standing is the most intense exercise.

Although I have long known that exercise has countless benefits, I have always wanted to take the first step, but when I see people around me who are struggling to exercise,Spend an hour or two sweating in the gym every day., who all want to back down?

However, watching a documentary recently actually made me take the first step of exercise, because it let me know that exercise is not a hard job at all!

The documentary also said: those who work hard in the gym for an hour or two are simply thankless. As long as you master the method,Just 2 minutes a week., you can achieve excellent fitness results!

The host of this documentary is?Professor michael mosley, a medical journalist(Dr Michael Mosley), he has always been a lazy man, and in the matter of exercise, he wants to?Spend the least effort?Get the biggest return.

Medical journalist Dr Michael Mosley.

In order to realize his dream, the whole BBC team is in full swing, accompanying him to visit sports experts in various fields and looking for?Super high efficiency?The exercise method. This process was filmed as the documentary The Truth About Getting Fit.

Anyone who wants to exercise but doesn’t want to work hard must not miss this documentary!

At the beginning of the documentary, Michael will?overturn?A popular saying: "You can stay young and healthy by walking 10,000 steps every day".

The idea of 10,000 steps first came from a marketing campaign more than 50 years ago. A Japanese company invented the "10,000-step pedometer", and while sponsoring the Tokyo Olympics, it relied on a sentence.10 thousand steps a day"The advertising words are deeply rooted in people’s hearts.

But do you have to walk 10 thousand steps to be effective?

In order to find out the truth, Michael consulted Professor Rob Copland of Harlem University in Sheffield, and he will arrange a controlled experiment to verify this theory.

Note: In order to make the public understand the BBC documentary,

Experimental methods with small samples and not rigorous enough are often adopted, but they still have certain reference.

He divided six people into two groups to take part in the experiment:

The first group (Gillian, Dave, Dai Lun): Walk 10,000 steps every day, unlimited speed, about 8 kilometers.

Group 2 (Nathan, Gary, Judy): 10 minutes three times a day,doubleAbout 3000 steps, about 2.4 kilometers.

In the experiment, both groups wore activity monitors, which could track their activities throughout the day and monitor their heart rates. Professor Copeland said that the increase in heart rate caused by exercise can?Strengthen heart and lung function, is an important indicator to measure the effect of sports.

After the experiment began, the members of the first group worked hard to achieve the goal of 10 thousand steps, because 10 thousand steps were too difficult to complete!

Of the three people, only Dave and Dai Lun managed to finish the task. Gillian washed the bowl and deliberately walked back and forth several times, but only walked more than 5000 steps in one day.

In contrast, the members of the second group are much more relaxed.

They met for a brisk walk, and 10 minutes passed quickly. Unconsciously, they easily completed the indicators.

On the one hand, it is difficult to move forward, and on the other hand, it is easy to reach the standard. What is the effect of their exercise?

Professor Copeland published?Surprising?Experimental results of:

Although the first group is more tired, the exercise effect of the second group is better.?better!

He explained that this is because the brisk walking adopted by the second group belongs to moderate to intense physical exercise, and the intensity is increased by 30% compared with the usual walking.

Comparatively speaking, although the walking time of the second group is shorter, the intensity of cardiopulmonary exercise is greater, so the effect is better than that of the first group.

Michael’s first discovery saved him 7000 steps every day.

But lazy, he is not satisfied with this! Last time he found out?More labor-saving?Movement, this time he turned to.?More time-saving?The exercise method.

He went to visit.?High intensity intermittent exercise(HIIT) expert Niels worrall.

Experts from worrall arranged for six white-collar workers to participate in a five-week exercise program.

Before the exercise, the six people first took an aerobic fitness test.

Aerobic fitness refers to human intake, transportation and utilization.?oxygen?The ability. People with good aerobic fitness will run for 1000 meters without breathing. On the contrary, people with poor aerobic fitness will be panting after climbing several stairs.

After testing aerobic fitness, Niels worrall asked these white-collar workers to do it on a spinning bike every week?3 groups of 40 seconds?HIIT training.

In other words, every week they only need?Exercise for 2 minutes. After five weeks, these people only exercised in total.?10 minutes.

However, five weeks later, when six white-collar workers took the physical fitness test again, their?Aerobic fitness?An average increase of 11%!

Worrall explained,

This is because HIIT can stimulate deep muscles.

Deep muscles are hidden around the bones of the body, which plays a role in coordinating the body and supporting the bones and joints. Ordinary exercise is difficult to involve, and HIIT can activate them.

In addition, HIIT can rapidly consume muscle glycogen.

Muscle glycogen is the sugar stored in muscle. When people exercise vigorously, the body will break down the sugar in muscle and provide energy for the body.

Worrall asked a white-collar worker to do three groups of HIIT for 2 minutes, and compared his muscle glycogen levels before and after exercise.

The results showed that his muscle glycogen level decreased.?24%?As much as, if you use other sports methods, you may have to?45 minutes?In order to achieve the same effect.

Finally, HIIT can also exercise the heart and lungs and improve the whole cardiovascular system.

HIIT is good, but it is not convenient for everyone to go to the gym to ride a spinning bike. In order to let everyone enjoy the benefits of HIIT, Michael specially invited Beth Philips from Nottingham University to design a set of HIIT training without any auxiliary tools.

This training takes a total of 5 minutes, namely:1-minute arm jump, 1-minute squat, 1-minute run, 1-minute arm jump, 1-minute squat..

You can also easily complete this set of movements at home, and the exercise effect is comparable to HIIT of spinning bike.

Besides HIIT,Strength training?It is also a very popular exercise method in recent years.

In order to find out?Have the best effect?The way of strength training, Michael came to Glasgow University, where sports researchers Stuart Gray and Nai Stefanacci are working.?Test weightlifting and light liftingWhich effect is better.

The experiment they designed was completed by five women. Before the experiment began, all the people took a strength test, and the researchers will record what they can lift.?maximum weight.

During the experiment, the participants lifted the dumbbells with one hand and the light dumbbells with the other, and both hands should be lifted until they have no strength. The hand that lifts light things takes longer to reach the fatigue point than the other hand. Their legs also had a heavy and light exercise.

For six weeks, they conducted two groups of training every week. After the training, they accepted the strength test again, and the results showed that:

There is no difference between lifting weights and light weights at all, and the muscle strength of both hands and legs is almost the same.

Their hands muscles have been strengthened by 18%-19%, and their legs muscles have been strengthened by 25%, and there is no difference because of the different weights on both sides.

After learning this result, five participants said that they would rather lift weights because of the short time.

Therefore, it is simple to save time by lifting weights.

Unlike strength training, running is the most popular sport because it doesn’t need any instruments and equipment and is very convenient to perform.

In order to explore the truth of running, Michael came to St. Mary’s University in London and asked John Brewer, an exerciser, about it.?run?The problem.

We always think that running will damage the knee joint, but is this true?

Brewer said,Running will not only hurt the knee joint, but also benefit it..

This is because the regular pressure generated by running can bring more oxygen and nutrients into articular cartilage.Conducive to cartilage repair and growth.

Michael, the host, found it unbelievable, so Brewer asked him to do an experiment to compare knee pressure.

In the experiment, Michael put a sensor on his knee, then walked a certain distance at the designated position, and then he ran the same distance.

Then, the computer will analyze the pressure on the knee when walking and running.

As can be seen from the above picture, although the pressure on the knees is greater when running than when walking,But it takes less time to cause stress.. Generally speaking, the time for running to produce stress is only half of that for walking, because people have longer strides and shorter contact time between their feet and the ground.

The blue bar represents the stress time caused by walking.

The red column represents the stress time caused by running.

In the above experiment, the total pressure on Michael’s knees when he runs is smaller than when he walks.

Brewer said that these pressures are completely within the acceptable range of the human body, because the human body structure can fully load walking and running. Imagine if our ancestors couldn’t run, how could they survive the competition of nature?

Whether it is to avoid or chase prey, people need to use the skill of running, which has been used to this day.

Nevertheless, if you run in the wrong way, such as running too fast, running for too long, running on uneven or slippery ground, you may cause injuries.

After visiting a number of sports experts, Michael has mastered four major exercise truths:

1. Walking 10,000 steps slowly every day is better than walking 3,000 steps quickly.

2. HIIT for 2 minutes per week can effectively improve aerobic fitness.

3, it takes a short time to lift the dumbbell to fatigue, which can effectively strengthen the muscles.

4. Running won’t hurt your knees.

Michael’s next stop is to visit a physiologist, Professor Sirsa Osullevin. He wants to know why some people love running so much.

Professor O ‘Sullivan said that people will produce endogenous pheromones when running. This kind of substance spontaneously produced by the human body is very similar in structure to the alcohol in * *, which will excite.?Positive mood, increase appetite, bring pleasure..

Besides running, other exercises can also produce endogenous hormones, which explains why some people feel uncomfortable without exercise for a day. Because exercise can really make people happy. Professor O ‘Sullivan believes that "endogenous pheromone" is one set up by the body?Incentive mechanism to encourage exercise.

In order to let Michael witness the power of running, Professor O ‘Sullivan arranged for three runners to jog.

After running, the endogenous pheromone in participants’ bodies increased by 30% compared with that before running!

Professor O ‘Sullivan explained that the endogenous pheromone produced during this exercise is within a safe range and can make people excited to the right degree.

After reading "The Truth of Exercise", I was eager to try, and immediately did a 5-minute HIIT exercise, and sure enough, I immediately felt High.

It turns out that,Exercise can also be a simple and happy thing!Friend, you might as well try it!

　　(Health Times reporter Jing Xuetao) "You are my little apple, and I can’t love you too much …" A song "Little Apple" by China’s men’s group Chopsticks Brothers is popular all over China, and its catchy lyrics are also deeply rooted in people’s hearts. "Little Apple" also vividly summarizes the definition of healthy beauty in China. So how can we become an "apple woman" with rosy complexion and skin like jelly? The reporter went to the dermatology department of Wangjing Hospital of Chinese Academy of Traditional Chinese Medicine and inquired about several beautiful secrets with Director Shu Youlian.

　　Dry, just drinking water is not enough

　　Spring is very dry. In order to alleviate the feeling of dryness, people "naturally" think that drinking more water can replenish water. Director Shu Youlian said that this is a wrong concept. People drink water to replenish water consumption and promote metabolism. Drinking too much water for a long time or drinking a lot of water for a short time, the human body must use urine and sweat to discharge excess water, causing a burden on the kidneys.

　　To relieve dryness, we should give priority to food supplement and eat more seasonal fruits and vegetables. Fruits and vegetables belong to yin-nourishing foods, which have the functions of nourishing body fluid, moistening dryness, clearing heat and relaxing bowels. Fruits and vegetables contain a lot of water, which can clear heat and purge fire, moisten intestines and clear lung, not only supplement body fluids and vitamins, but also improve the adverse effects of dryness on human body.

　　Wash your face with cold water.

　　Many people advocate washing your face with cold water. They think that on the one hand, stimulating facial skin with cold water can improve the adaptability of human body to cold, and then enhance immunity, which is good for health. On the other hand, washing your face with cold water can shrink pores and tighten skin. Director Shu Youlian believes that washing your face with warm water is the basis of skin care. The skin on the face is delicate and should be taken good care of, not stimulated. Using warm water when washing your face can make your skin open pores, discharge stolen goods, and secrete oil to lock moisture, thus forming a protective layer of your skin. In addition, the shrinking process of pores is very fast, almost at the same time, so there is no need to wash your face alternately with hot and cold water in order to converge pores, and alternating hot and cold can easily lead to the phenomenon of red blood on your face, which may be aggravated for people with sensitive skin.

　　Combine inside and outside to create hair.

　　In spring, many people’s hair will also appear dry and dull. "Hair is like a crop. If you treat it well, it will treat you well," Director Shu Youlian said with a smile. "If you want to have a beautiful hair, you have to combine the inside and the outside."

　　From the inside, first of all, we should eat on time, balance nutrition, ensure the time and quality of sleep, relax and have a good mental state. Secondly, in terms of diet, we should pay attention to iron supplementation. Iron is an essential trace element in the human body, but now people are generally deficient in iron. Malnutrition and iron deficiency anemia caused by long-term iron deficiency will lead to dry and split hair, loss of luster and even large-scale hair loss. In this regard, you can choose to stir-fry in an iron pan or eat iron-containing soy sauce to supplement iron.

　　From the outside, in the usual shampoo and hair care, we should try to choose big brands with quality assurance and use less shampoo with oil control effect. After washing your hair, you should squeeze the water out with a dry towel by gentle pressure before using the hair dryer, so as to shorten the use time of the hair dryer as much as possible, and the distance between the hair dryers is better, preferably 15cm-17cm.

　　Take a bath, don’t wash too clean.

　　There is a layer of basal cells deep in human epidermis, which differentiate into keratinocytes day and night. These keratinocytes protect the whole body, gradually move to the surface and die during metabolism, and the outermost aged keratinocytes will naturally fall off in pieces. Daily bathing can wash away the skin scale mixed with the stratum corneum and skin sweat, which has a certain protective effect on the skin.

　　There are some people who love cleanliness, take a bath too often, and they are worried that they will not be clean. They often wash their bodies with rubbing towels and exfoliating bath lotion. Director Shu Youlian said that there is a layer of oil on the surface of human skin, which can protect and moisturize the skin. The frequency of showering is too high, especially the frequent use of bath towel or shower gel will inevitably destroy the oil layer, leading to dry skin, itching and other symptoms, and easy to make the skin age early.

　　Cctv news The system of "Special Commissioner for Science and Technology" (hereinafter referred to as "Special Commissioner for Science and Technology") originated in Nanping, Fujian, aiming at assisting the development of advantageous industries and the construction of agricultural science and technology parks through the transformation of scientific and technological achievements, and helping rural revitalization. However, the problem that science and technology commissioners often encounter in the process of serving tea farmers and tea enterprises is the problem of funds.

　　According to the introduction of the local financial supervision bureau of Fujian Province, the relevant financial institutions in Fujian have innovated the "tea industry finance+specialized" model, provided comprehensive financial services in the areas of "financing and intelligence, industrial support, knowledge popularization and ecological construction", and promoted the tea industry to become a dominant industry in Fujian together with the "Fucha. com" platform.

Lin Jie, president of Nanping Central Sub-branch of the People’s Bank of China, went to tea enterprises for guidance and set up a "workstation for financial technology commissioners".

　　The Nanping Central Sub-branch of the People’s Bank of China strengthened the cooperation between government, banks and enterprises, and guided financial institutions to launch various models such as "tea finance+Kurt loan" and "technology+finance+tea industry" to organically integrate the policy of benefiting farmers with financial products. At the same time, it instructed financial institutions to set up a "workstation for financial science and technology commissioners", and provided support to 634 tea enterprises and farmers in industrial support and precise poverty alleviation.

　　Bank of China Nanping Branch designed and launched the "Cote Loan" liquidity product, and Nanping Finance Bureau invested 2 million yuan to establish a credit enhancement fund pool as the government risk compensation for the credit enhancement fund loans of enterprises led, founded and served by Nanping Science and Technology Commissioner. When the credit enhancement project loans suffered losses, the loan losses were supplemented by 50% of the credit enhancement part. The bank also plays the role of precise drip irrigation of tea finance, promotes the coordinated development of tea industry, tea culture and tea technology, and makes tea economy a magic weapon for rural revitalization and a benchmark for green development.

　　Nanping Branch of Postal Savings Bank signed a strategic cooperation agreement with Nanping Science and Technology Bureau, set up a service team of financial science and technology commissioners, and jointly launched the "Kurt Loan", which mainly provided credit financial support for enterprises founded, led or served by science and technology commissioners; Open up green approval channels and give preferential interest rates. With the guidance of the science and technology task force and the blessing of financial resources, the capital needs of tea enterprises for production, processing and technology upgrading have been effectively met.

　　In Zhenghe County, Fujian Province, it was not easy to evaluate the value of local tea due to the variety of tea and the influence of tea production technology and tea producing area, which also made tea enterprises encounter difficulties in financing. Nowadays, through the combination of tea financial services and the special system, the problem of value evaluation that plagues local tea financial services has been effectively solved.

　　With the assistance of the special workstation, the county broke the financing bottleneck of tea warehouse receipt pledge due to value evaluation, quality certification and other issues. At present, more than 8,000 boxes of white tea have entered the high-standard intelligent management, with a total value of more than 30 million yuan, and it is estimated that more than 18 million yuan can be raised.

　　After the "Fuxing" was put into storage, the first process was cleaning. The picture shows the staff taking a bath for the Fuxing. Photo by Sun Guangzhe

　　On June 26th, 2017, Fuxing, the EMU train with the highest speed in China, was officially put into operation, which opened the new speed of China high-speed railway. On the eve of the Spring Festival, the reporter from Zhongxin. com came to the operation office of Jinan East EMU in Shandong to visit the "nightlife" of Fuxing after work.

　　"Good traction rod, good air duct and good axle … …” In the maintenance depot, Wang Xiao, the foreman of the special maintenance team of Jinan East EMU, is leading more than 10 colleagues to do a "physical examination" for a train of Fuxing, which just got off work.

　　The picture shows the EMU warehousing. Holding professional lighting and video equipment, the staff crouched on both sides of the car for a series of procedures such as watching, smelling and listening. Sha Jianlong photo

　　The "Fuxing" that is being "physically examined" has 16 carriages, which are parked on the trench track about 2 meters deep. The maintenance personnel are located in the front, sides, roof, under and inside the car for operations.

　　Wendy Wang told reporters that "Fuxing" must pass the tread diagnosis and pantograph detection before entering the maintenance depot. Just like CT, infrared detection equipment conducts all-round detection on the tread of the wheelset and the high-voltage power receiving equipment at the top of the train, and transmits the monitoring data to the professional computer for "expert consultation".

　　"After warehousing, the first process is cleaning." Wendy Wang said that after the power failure and bow lowering of the EMU, the special car wash liquid for the EMU was sprayed from the water outlet, and the professional "SPA masseur" beside the track was "Fuxing" and "taking a bath". Under normal circumstances, EMUs should be disinfected and cleaned by outdoor automatic washing machine before entering the warehouse. However, due to the cold weather in winter, the cleaning work must be carried out indoors by professionals to prevent the EMU from catching a cold.

　　After cleaning, professional "doctors" will start a "full physical examination" of the EMU. According to the technical regulations and technological requirements, Harmony and Fuxing should enter the motor depot every 4,400 kilometers or 48 hours and every 6,000 kilometers or 48 hours for first-class operation and maintenance.

　　"To ensure that ‘ Fuxing ’ The motor train runs at a high speed and smoothly, and every bolt and every part of the train must be accurate. " Xu Qingji, the "post-90s" ground mechanic of Jinan East EMU Operation Institute, is a member of the maintenance team, having repaired CRH2, 5, 380A, B and other vehicles. He told reporters that if problems are found during maintenance, they need to call superiors through real-time intercom equipment for diagnosis and maintenance.

　　"Fuxing" is an independent research and development emu with independent intellectual property rights in combination with China’s application needs, which is more perfect and superior than the emu models that it overhauled before. Xu Qingji said that it unified the operation interfaces, passenger pages and operation modes of different OEMs, and also completely unified all interfaces and parts, established a brand-new China high-speed train standard system, and realized mutual standby, reconnection, rescue and hot standby of trains.

　　In addition to the overhaul of the running gear, traction, braking, pantograph and in-vehicle facilities of Fuxing, its "brain" — — The maintenance of "ATP" system is particularly important. According to Wang Weina, chief of the ATP analysis work area of Jinan East EMU, the ATP system on board the high-speed rail is equivalent to a "black box", which is not only a monitoring system, but also records the running status of the high-speed rail in real time and transmits it to the monitor. It is also a traffic control system, which can command the safe operation of vehicles according to the track information ahead.

　　Wang Weina said that when overhauling, professionals should clean up the dirt on the transponder of vehicle-mounted equipment to ensure that the transponder responsible for receiving and sending information is always in good working condition. "After ensuring that all equipment and facilities are kept in normal condition, the train can be put into operation."

　　"Although the work is hard, I am very proud whenever I see a train of EMUs running normally after team maintenance." During the period of Spring Festival travel rush, the professional "doctors" of Fuxing will still stick to their posts and "escort" people’s travel. (End)
