In the 52nd minute, the Syrian team seized Zhang Linpeng’s mistake and made a counter-attack. Soma made a cross in front of the goal, and Samia, who was outflanked, scored an empty goal, but the goal was invalid because he was offside.

In the 59th minute, Kruma made a world wave with a long-range shot, and the national football team fell behind 0-1.

After the last 1-1 draw by Malaysia, the national football team once again fell into the whirlpool of public opinion.

The boos of the fans after the game, the shouts of "money back" at the scene, and the pictures of Zheng Zhi glaring at the fans all spread on social networks …

However, the national football team still shows no signs of rebounding. In the warm-up match against Syria on the evening of 12th, the national football team lost 0-1 at home, and will usher in the preliminaries in November with a record of one draw and one loss, and welcome the South Korean team and Thailand team.

What is even more embarrassing is that only 12,367 fans came to the Phoenix Mountain Stadium in Chengdu this game, only half of the last game …

Li Lei made a cross from the left and passed it directly to the opponent’s head coach Cooper …

Confidence in jankovic and Lei Wu

The result of the national football team’s last match against Malaysia was not satisfactory. The 1-1 draw did not meet the expectations of the fans, which also attracted some criticism from the outside world. Did coach jankovic feel the pressure?

However, jankovic said that he is more concerned about the technical and tactical level. "There are two opportunities at the last moment. Even if we grasp the victory, we can’t avoid the problem. These things are what I should be busy with."

"For me, the pressure is that I haven’t played for three years. Now I enjoy it. There will be no pressure in the football industry." Jankovic said.

Li Shuai was seriously injured in the last game, and his teammates held his jersey and entered the stadium.

In the first match against Malaysia, three players, Lin Liangming, Li Shuai and Gao Zhunyi, were injured, so jankovic made some adjustments to the starting players, and the tactical system was 3-4-1-2 at the beginning of the second half of the last game.

The goalkeepers are Yan Junling, three central defenders Zhang Linpeng, Jiang Guangtai and Wang Shenchao, wingers Sun Guowen and Li Lei, double-waist Li Ke partners Xin Xu, Xie Pengfei plays the front waist, and double forwards are Lei Wu and Daniel F. Akerson.

Lei Wu is in the game.

Before the game, Lei Wu was also asked about his role as a veteran in the team.

"Understanding what the fans expect of me, my position as a striker may be to score goals. In fact, the head coach stressed to us from the first day that defense is not the responsibility of the defensive players, and everyone needs to work hard. This is also the overall idea brought to us by the head coach. "

Lei Wu admits that all players in the national team now cherish the opportunity to play. "I hope I can lead young players, set a better example and play my role on the road to the World Cup. Not only on the court, but also in life, so that everyone can unite. "

The victim of the national football team

There is no shortage of stories in the last five confrontations between the national football team and Syria.

In the top 12 of the 2018 preliminaries, Gao Hongbo’s team lost to South Korea 2-3 away and drew Iran 0-0 at home. At this time, the outside world had great expectations for the national football team to beat Syria. As a result, it lost to the opponent 0-1 in Xi’ an. This game directly led to Gao Hongbo’s subsequent class …

The second leg of the match between the two sides was held in Malacca, Malaysia, and the national football team had to win in order to take the initiative in qualifying-Wu Xi’s post-insertion and Gao Lin’s penalty once helped the national football team to overtake the score 2-1, but in the last minute of injury time, Syrian central defender Saleh used a free kick to tie, and finally the national football team was 2 points away from the third place in the group.

Zhang Linpeng fought with his opponent.

Then in October, 2018, in Nanjing, the national football team played a warm-up match with Syria. Four days ago, the national football team held a 0-0 draw in Suzhou and India. As a result, the Syrian team was very embarrassed. Gao Lin’s long-range shot had no angle and strength, but the Syrian goalkeeper let the ball roll into the goal from his own hand, and finally the national football team won 2-0.

Coincidentally, in the 2022 preliminaries, the two sides met again in the top 40 stage.

The national football fans at the scene.

The first leg of the match was held in Dubai, and in the second half, Zhang Linpeng knocked Herribin’s cross into his own goal, and the national football team lost 1-2. Lippi angrily chose to resign after the game, and this press conference became one of the "black shots" in the history of China football.

In the second round match in Sharjah, the national football team won 3-1 and successfully qualified for the top 12.

Xin Xu tackles in the game.

How to play the preliminaries in this state?

In the World Cup Final 36, Syria is in a group with Japan and North Korea, so the Syrian team Cooper attaches great importance to the warm-up match against China-including goalkeeper Alama, attacking midfielder Mavas, high center Omar and other players who have played against the national football team many times in the past years.

Cooper said, "For me, the previous game experience with China is very valuable, and we also need to prepare for the preliminaries. What needs to be noted now is that the head coach and players in China have changed, which is very important information."

After the Syrian player scored, he made a celebration of Cristiano Ronaldo.

Judging from the content of this game, the Syrian team is actually not at its best, and the threat to the national football team is not as good as that of Malaysia in the last game.

However, they still controlled the game in the second half. A world wave broke the goal of the national football team and a goal was cancelled because of offside.

The attack of the national football team is still not improving, accompanied by many mistakes in the backcourt and Li Lei’s cross from the left, which was directly passed to the opponent’s head coach Cooper …

In this state, how should the national football team face the preliminaries in November? How to face South Korea and Thailand? All that remains is the unknown …

27-year-old Lily (pseudonym) was found to have an ovarian teratoma about 6 cm in size when she was examined in the hospital at the beginning of the year. At that time, the doctor advised her to have an operation as soon as possible.

But for some concerns, Lily has been procrastinating. And just see the beauty salon near the company for publicity, saidEssential oil massage can maintain ovaries and help reduce cysts.So Lily decided to try.

Until June, Lily had severe abdominal pain, accompanied by nausea and vomiting, and her family quickly sent her to the emergency department. When looking for the source of pain, the doctor found a slightly larger mass in Lily’s right accessory area. Considering the torsion of ovarian cyst, he quickly arranged surgery for Wenwen.

On further examination, Lily’s ovarian cyst is indeedA twist of 720 degrees occurred.Fortunately, it was found in time and the operation was a success.

The doctor told Lily that she had a teratoma herself.While massage increases local abdominal pressure.Local posture changes, without the risk of cyst torsion and rupture.

Ovary also has a life span. According to normal physiological laws, ovarian function is at its peak at the age of 25-35. When women are over 35, ovarian function will gradually decline.

Among them, menopause is a sign of premature ovarian failure in women. According to statistics, Chinese womenThe average age of natural menopause is about 49 years old.However, due to living habits, mental stress and other reasons, most modern women have an early menopause trend.

Ovary has two major functions,One is reproductive function.It can store eggs and ovulate to prepare for life;The second is responsible for regulating endocrine function.Let women have Q-elastic skin and a concave-convex figure.

However, in recent years, studies have found that premature ovarian failure in women is more and more common. Premature ovarian failure is also called early-onset ovarian insufficiency. Before the age of 40, due to ovarian function decline,Persistent amenorrhea occursA group of diseases with high gonadotropin and low estrogen status.

At present, there are three recognized diagnostic criteria for premature ovarian failure: ① age < 40 years old; ② Amenorrhea time ≥6 months; ③ twice (more than one month apart) blood FSH (follicle stimulating hormone) > 40mIU/ml.

Once premature ovarian failure occurs, there is no room for recovery.Only through early detection and early control can the recession be delayed..

For women, premature ovarian failure not only means getting old in advance and lacking hormones for a long time, but also mayCauses osteoporosis, cardiovascular disease, Alzheimer’s disease and increases the risk of cancer.Wait a minute.

Premature ovarian failure will bring health threats to women. What causes will affect ovarian function?

One is pathological factors.About 10% of premature ovarian failure is related to chromosome abnormality, and some of it is caused by autoimmune disorder, as well as viral infection, such as HIV, cytomegalovirus, tuberculosis, malaria, etc., which will all affect the ovaries.

The second is iatrogenic factors.In the process of ovarian surgery, radiotherapy and chemotherapy, the whole body organs are more or less damaged.

The third is bad living habits., such as frequencyNumerous abortions, often staying up late, smoking, drinking, and losing weight unscientific.Etc., will have a negative impact on the ovaries.

What are the manifestations of premature ovarian failure?

• Menstrual disorder;
• Symptoms of estrogen deficiency, such as hot flashes, night sweats, upset, decreased libido, vaginal dryness, etc.
• Emotional instability, such as emotional excitement, depression, irritability, insomnia, etc.;
• Fertility declines.

Many people question whether ovarian decline has an impact on sexual life.

In fact, the maintenance of ovarian function mainly depends onHypothalamus-pituitary-ovary axisAt present, there is no evidence that the decrease of sexual life is related to follicles or ovulation.

In order to prevent premature ovarian failure, many people may go back to some beauty salons or massage shops to do "ovarian maintenance". Is it really effective?

You know, the ovary is located in the bilateral iliac fossa area below the navel, in the deep position of the lower abdomen.From the outside of the stomach, it is simply impossible to touch..

Most of the essential oil can only act on the skin surface, even if it penetrates into the skin and enters the blood circulation of the whole body, it has little effect on the ovaries. At present, there is no diagnosis and treatment guide to recommend the use of massage to improve ovarian function.

In addition, it is not recommended to take drugs orally to prevent it. If these drugs really work, they are probably added with hormones.If hormone is used under the condition of unknown composition and dosage, it will cause disorders such as breast and uterus.It is easy to induce the disease, even worsen the disease, and increase the risk of tumors such as uterus and ovary.

If you are diagnosed with premature ovarian failure, don’t be too anxious. In a short time, hormone supplementation can alleviate the symptoms of low estrogen. If there is a need for fertility, you can discuss with your doctor the plan to promote ovulation and combine assisted reproductive technology to complete pregnancy.

We should also take relevant precautions in daily life, such as quitting smoking and drinking, paying attention to a balanced diet, releasing stress, maintaining an optimistic mood and keeping internal hormones in a steady state. When you notice signs of premature ovarian failure, don’t delay because of face. Early detection and early treatment are the best ways to delay the decline.

Physical activity preparation questionnaire

Before you plan to exercise, please read carefully and answer the following six questions according to your actual situation for your safety.

whether or not

□□ Did the doctor tell you that you have a heart disease or can only participate in physical activities recommended by the doctor?

□□□ Have you ever felt chest pain or severe breathlessness when you are engaged in physical activities or sports?

□□ Since last month, have you ever felt chest pain or severe breathlessness when you have not participated in physical activity or exercise?

□□ In the past 6 months, have you ever fallen down or lost consciousness because of dizziness when you were engaged in physical activities or sports?

□□□ Do you have any bone or joint pain or dysfunction aggravated by physical activity or exercise?

□□ Did the doctor tell you that your blood pressure is over 180／110mmHg?

If you answer "Yes" to any of the above questions, please stop taking part in this fitness exercise and pay attention to: (1) consult a doctor before taking part in the fitness program and explain which question in the questionnaire is answered "Yes"; (2) Take part in fitness activities step by step, gradually adapt, the intensity of exercise should not be too large, and the time should not be too long; (3) You can restart the fitness mode that has been proved to be safe; (4) You can also participate in activities recommended by doctors or activities allowed by doctors; (5) timely use of necessary medication.

If you answer "No" to all the above questions, you can continue to exercise, but please pay attention to the following: (1) Take part in a large amount of exercise or exercise intensity gradually to avoid excessive fatigue; (2) Take part in further health evaluation, and work out the best fitness program accordingly.

Note:This questionnaire was established by the research group of Professor Wang Zhengzhen of Beijing Sport University with reference to relevant materials. It is suitable for people aged 15-69, and people over 69 should consult their doctors before doing fitness activities.

In recent years, with the in-depth implementation of national fitness, people’s participation has been continuously improved, and "more exercise and less illness" has increasingly become a social consensus.

What are the benefits of regular exercise to human health? What are the important principles of the scientific movement? How can we avoid sports risks? Our reporter interviewed Zhang Yimin, a professor at Beijing Sport University and director of the Key Laboratory of Sports and Physical Health, and asked him to answer questions.

Late-night exercise is extreme

Scientific movement is a good doctor. "Scientific exercise can not only effectively improve heart and lung function, promote human metabolism, strengthen muscle and ligament strength, but also make people happy physically and mentally, enhance their ability to resist stress and promote their physical and mental health." Zhang Yimin said that "integration of physical education and medicine" is an important way to implement the Healthy China Action, which plays a positive role in improving and promoting people’s health.

Is there a best time to exercise in a day? "In fact, when exercise has little effect on the fitness effect. From the factors that affect the fitness effect, the key is that the exercise load should match the individual’s physical health." Zhang Yimin introduced that the time period of people’s exercise is mainly influenced by the schedule. "Take me as an example, I am busy with teaching and preparing lessons during the day and have no time to exercise, so 18: 00-20: 00 after work will be the best time for me to exercise."

In recent years, some gyms in first-tier cities have launched 24-hour gyms to cater to the "special work and rest time" of office workers. According to the fitness statistics released by Leke in July last year, in Beijing, the proportion of fitness people from 22: 00 pm to 8: 00 am the next day is 12.8%. In the whole country, the proportion of members who exercise during this period is close to 10%.

Do sweaty exercise in the middle of the night when you should be sleeping. Is this exercise a plus or a minus for your health? "I think it is to reduce points. Late-night exercise is a bit extreme, which may disrupt the biological rhythm." Zhang Yimin reminded that it is more appropriate for office workers to squeeze out 30 minutes to 1 hour for exercise before dinner after work. If you occasionally work late in special circumstances, such as getting off work at 10 o’clock in the evening, and you really want to exercise, it is recommended to take a light activity for 30 minutes and sweat. "You know, rest is also an important way to eliminate fatigue, and exercise is systematic and long-term. If you don’t exercise one day, you can continue to exercise later. It is unnecessary and discouraged to exercise late at night."

Now it is the spring season, and many people who have been "cats" for a winter have begun to go outdoors and exercise their muscles. "In fact, any season is suitable for exercise, but beware of extreme weather." Zhang Yimin stressed that don’t exercise in cold, hot, high humidity, strong wind, pollution and radiation environment; The temperature difference between spring and autumn is large, and the temperature is low in the morning and evening. Pay attention to the influence of temperature and wind when exercising; Exercise in summer should guard against heatstroke; If there are special circumstances such as smog and sudden drop in temperature in winter, it is not recommended to do outdoor sports.

Don’t forget to stretch after exercise.

"Generally speaking, moving is definitely better than not moving." In Zhang Yimin’s view, scientific movement needs to follow the basic principles of safety, overall accuracy, step by step, perseverance and so on, and in terms of exercise mode, exercise intensity, exercise frequency, exercise duration and so on, it should be adapted to local conditions according to people and time.

Security principle. "It is very important to do warm-up activities before exercise and stretching exercises after exercise, but the latter is often ignored by many people." Zhang Yimin pointed out that during exercise, human muscles constantly contract and exert their strength, and their elasticity decreases. If they don’t stretch for a long time after exercise, these problems may be brought about: local inflammatory factors and metabolic wastes can’t be discharged, which leads to increased fatigue and slower recovery; The next training with fatigue will increase the risk of injury and induce sports injuries such as "running knee".

"If the muscles in the hind leg feel hard, and the knee joint is already tired or faintly uncomfortable, it may be caused by strain caused by not stretching after exercise." Zhang Yimin introduced that studies have confirmed that stretching after exercise helps to relax muscles and improve muscle elasticity, which is one of the "magic weapons" to reduce sports injuries. Stretching practice time should be at least 10 minutes, or about 1/3 of the duration of exercise.

Principle of comprehensiveness. Different types of exercise will bring different fitness effects, and the exercise methods are better, preferably including aerobic exercise, strength training and flexibility training. Aerobic exercise can make people’s heart and lung function better, and it also directly affects the activity ability of the whole body organs; Strength training helps to improve muscle strength and avoid problems in daily activities such as walking, running and jumping caused by insufficient strength; Flexibility training is stretching exercise, which can improve the stretching ability of muscles and effectively prevent sports injuries.

Principle of accuracy. As long as the fitness action standard and exercise load are reasonable, sports injuries can basically be avoided. The "fake" action of posing, not exerting force and nonstandard "wrong" action are the main causes of sports injury accidents. For example, "sit-ups with your head in your arms" is a typical non-standard movement, which may lead to sports injuries. If your hands are lightly placed behind your head or on your ears or chest, you should mainly use your abdomen to pull your trunk, instead of using your hands and head, which is not harmful, but also can exercise your core muscles well.

The principle of gradual progress. The frequency of exercise varies from person to person. Generally speaking, you should exercise at least three times a week, and it is best to gradually increase it to five times a week to ensure the fitness effect. No matter what your physical fitness level is, you should do what you can when exercising, and you can’t ignore the signals sent by your body. If you have dizziness, dizziness, chest pain, nausea, shortness of breath, palpitation, vomiting and other symptoms during exercise, you should stop exercising immediately and seek medical advice in time. If you have persistent and obvious fatigue after exercise, you should appropriately reduce the exercise time or times. When you feel in good physical condition, you can also exercise for a while.

The principle of perseverance. To achieve good fitness results, it is essential to participate in sports persistently. It is suggested that according to one’s physical health and sports ability, an achievable exercise goal should be established and a feasible exercise plan should be made. Work and rest should be combined in life to avoid giving up the exercise plan because of being too busy or too tired; We should understand sports from the height of "exercise is a part of life" and stick to it for a long time.

Avoiding sports risks in advance

Zhang Yimin pointed out that for most people, physical exercise is safe. However, special groups such as the elderly, children, pregnant women, menstruating women, those with heavy weight, and those who have been under exercise for a long time need to pay special attention to avoid risks before exercise.

People who don’t usually exercise regularly, especially the elderly, must start with low intensity (about 50% or slightly less of the maximum heart rate), short time (about 10 minutes) and long interval (exercise for 2-3 days a week), and then gradually improve the intensity after 3-6 months of adaptation; Children are highly excited during exercise, but they are easy to get tired. It is best not to let children do a single exercise for too long. For pregnant women and menstrual women, high-intensity exercise is not recommended, but moderate exercise within the body’s tolerance, such as walking; Heavy people are not suitable for running, in case they hurt their knees.

"Inappropriate physical exercise, such as exercise in bad environment, untimely exercise, exercise beyond physical endurance, exercise of people with congenital or acquired cardiovascular diseases, etc., may cause and aggravate pathological changes in the cardiovascular system, and cardiovascular accidents may occur. In severe cases, sudden death may occur." Zhang Yimin introduced that the main symptoms of cardiovascular accidents include chest tightness, chest pain, heartburn discomfort, syncope, abnormal dyspnea, etc. Common diseases include coronary heart disease, myocardial infarction, myocarditis, congenital cardiovascular abnormalities, etc.

"Generally speaking, if there is no problem with cardiovascular health, the risk of cardiac arrest or myocardial infarction caused by moderate-intensity physical activity is low. Most of those who died suddenly during exercise have been diagnosed or have hidden cardiovascular diseases. " Zhang Yimin pointed out that although the incidence of vascular accidents in sports centers is not high, it is harmful. In order to avoid the occurrence of vascular accidents in sports centers, we should properly understand the relevant health knowledge, consciously make full preparations and pay attention to self-protection in cold or hot and humid environments before doing fitness exercises. Follow the basic principles of different people and step by step, adjust mental state and control exercise intensity, so as to achieve the best fitness effect.
