The basic technical essentials of badminton batting

The basic technical essentials of badminton batting

The badminton batting technique is ultimately reflected in the speed of the ball, the change, the ability to control and change the arc of the ball, the accuracy of the landing point, and the speed of the ball at the same hitting point, the point of the arc, the arc.Such changes.

  The basic technical essentials of badminton batting can be divided into gripping – hitting point – action coordination – control of the face – action consistency and so on.

  Grip: I have already introduced the correct grip posture and various changes.

A good grip method is correct and flexible, which is the basis of the hitting technique.

Do not hold the grip too tightly so that the wrist can fully exert force and control the size and direction of the hitting power.

  Batting point: The height to be hit by the hitting point, so the hitting is done when hitting the ball, instead of waiting until the ball has already approached the body.

The moment of hitting the ball should be the moment of the swing speed. The hitting force should not be too early or too late, and the strength of the force and the hitting strength.

  The mistakes made by good players are based on the pursuit of quick hitting, often premature or prematurely swinging, so that they can not exert the maximum strength at the moment of hitting the ball.

The solution is to calm down, relax your body and wrists, and have a good judgment on the ball before hitting the ball.

  Coordination of movements: The coordination of movements is the key to exerting strength. Coordinated movements can mobilize the strength of various parts of the body and concentrate on exerting strength.

Coordinated movements also come from a relaxed body, which can lead to stiff movements, movements that are too large or distorted, and thus insufficient force.

  Consistency of movement: When the master hits the ball, he can change a variety of ball and landing points, so that the opponent can’t judge before the ball is out. This is the consistency of the action.

  The consistency of motion requires that the backcourt action should be exactly the same when pulling the ball, killing the ball and hanging the ball. It is only different at the moment of hitting the ball.

The action in front of the net is the same. Grab the high point of hitting the ball, and the action of smashing, fluttering, pushing, and hooking can be completed.

The consistency of the action is the basis of the fake action.

Menstrual period, these weight loss methods can never be used

Menstrual period, these weight loss methods can never be used

Among the outpatients with “menstrual irregularities”, it was found that most of the young girls, a female patient controlled their weight through a specific diet, usually with high-pressure soup, aloe vera, melon, lettuce and other foods, the menstrual crampsDuring the period, the grapefruit diet was more effective.

  As a result, the patient found that the amount of menstruation was immediately reduced a lot, and the blood color was darkened. The situation in the second month was similar, and even the abdominal pain was uncomfortable, and the whole person was lost.

Before using this method to lose weight, most of these girls did not have a history of dysmenorrhea, and the cost was unpredictable.

  When menstrual cramps, in addition to full rest, but also pay attention to nutrition, cold food such as ice, cold drinks, grapefruit, grapefruit, pear, watermelon, coconut, orange, tomato, mung bean, lotus root, cucumber, bitter gourd, loofah, melon,Chinese cabbage, white radish, etc., must be avoided or eaten as little as possible.

Usually, after the combination of traditional Chinese medicine conditioning and food screening, the abdominal pain of these patients is improved.

  In addition to the specific diet weight loss method, short-term fasting method, slimming medicine slimming method, now popular is the Chinese side to lose weight.

The consequences are menstrual disorders, disrupting hormone secretion, and some people even lose weight.

The Asian Wall Street Journal recently reported that “not to be as thin as a muscle” seems to be the special psychology of the oriental women. In addition to the slimming method other than sports, there are people who try to “before and after”.

  This phenomenon was observed in outpatients.

In fact, eating less and moving is currently the only way to control weight, and shortcuts often tend to lose weight.

The regimen during the period is not difficult. For example, Western women like to take the opportunity to eat some chocolate. The Chinese long-standing longan red jujube soup, red bean soup, ginger and brown sugar are all good choices.

Older diabetes is more afraid of low blood sugar

Older diabetes is more afraid of low blood sugar

Older diabetes is more afraid of low blood sugar. Diabetes is a metabolic disease characterized by elevated blood sugar, but in its treatment, hypoglycemia is a problem worthy of attention.

The occurrence of hypoglycemia is often associated with excessive medication or timely meals after taking hypoglycemic agents, as well as a sudden increase in exercise or a reduction in food intake.

In addition, the elderly, liver and kidney dysfunction is likely to cause drug accumulation, is also an important factor.

When grasping the typical symptoms of hypoglycemia, most of the patients will have such symptoms of sympathetic abnormal excitement, such as worrying irritability, strange behavior, obesity, palpitation, pale, sweating and so on.

When these symptoms appear, the patient’s attention is generally noticed. By eating, eating sweets, sweet drinks or sweet fruits, and intravenous infusion of glucose, the hypoglycemia response changes quickly and the symptoms quickly disappear.

However, some elderly patients suffer from poor physiology, complications, poor endocrine regulation and autonomic secretion, and have poor response to hypoglycemia, resulting in early symptoms of hypoglycemia or symptoms of hypoglycemia.Not typical enough to be ignored or misdiagnosed.

Once the end of the millennium 2.


At 8mmol / L, it may cause hypoglycemia and coma.

According to statistics, in cases of hypoglycemia and coma, the number of elderly people over 65 years old is more than 65%, reflecting that elderly patients are the main indicator of hypoglycemia and coma, so sufficient evidence should be given.

Observance Precautions The early manifestations of diabetes hypoglycemia are mostly disturbance of consciousness, abnormal behavior, visual impairment and decreased body temperature, and then can be converted to stupor, lethargy or coma, which means the central nervous system is damaged.

On average, central nervous system damage in the early stages of hypoglycemia coma is reversible, with no sequelae after healing.

However, if the delay extends to long-term development, it becomes irreversible damage, causing disability and even life-threatening.

Relevant information indicates that if the hypoglycemia response lasts longer than 6?
12 hours, or coma more than 3?
After 6 hours, it may cause irreversible damage to brain cells.

It can be seen that elderly patients with diabetes are acutely alert to hypoglycemia and coma, and actively prevent hypoglycemia. The following precautions are taken: 1 Strengthen self-monitoring of blood glucose, and generally measure blood glucose daily?
2 times, but when the blood sugar is too much, it is best to test the blood sugar one time before the three meals and before going to bed after getting up in the morning.

2 appropriately relax the blood sugar control goals of elderly patients, such as glycosylated hemoglobin.

5% relaxed to 7.

Within 0%, the fasting blood glucose is within 7mmol / L, and the blood glucose is within 9mmol / L after 1 hour.

3 Avoid using gliclazide, which is too strong and too fast, and use long-acting glimepiride and glipizide with caution. Try to use mild, moderate-acting gliclazide.

It is best to use it in combination with metformin to exert synergy and reduce the incidence of hypoglycemia.

If insulin is given, it is best to add a long-acting preparation.

4 to achieve the law of life, eat on time, take oral hypoglycemic agents or insulin injections must be eaten in time.

5 The amount of exercise should be relatively constant, do not arbitrarily expand the amount of exercise, and carry candy with you for use as a spare when going out.

6 strictly follow the doctor’s advice, do not increase the dosage.

Check the dose before each dose to prevent overdosing.

7 Recurrence of hypoglycemia symptoms, should immediately restart the juice, sugary drinks, and then eat 1?
2 slices of bread or biscuits.

If the symptoms still do not relieve or have symptoms of central nervous system disorders, you should go to the hospital for treatment, and do not delay, in case of serious hypoglycemia and coma.


Dark circles don’t disappear for a long time or health problems

Dark circles don’t disappear for a long time or health problems

Dark circles do not disappear for a long time or health problems. Old Chinese medicine doctors remind different dark circles of different colors.

  First, the cyan dark circles cause blue skin around the eyes due to poor blood circulation, which is the most common type of dark circles; blue and black eye circles usually occur in the age of 20, and people with abnormal work and rest are particularly difficult to avoid because of their microvascularBlood blood pressure is slow, blood volume increases and oxygen consumption increases, and hypoxic hemoglobin increases. From the outside, the skin appears dark blue.

  Due to microvessels around the eyes, lack of sleep, eye fatigue, stress, anemia and other factors can cause congestion and edema around the eyes.

  Second, the black dark circles cause shadows on the eyes due to edema of the eyes and sagging of the bags under the eyes. They are loose-type dark circles. The three types of people are most prone to loose dark circles: a, thin skin, fine lines around the eyes, loose skin; b, the eyes are large, the facial features are deep; c, people who are prone to edema.

  Third, brown dark circles of the eyes, pigmentation dark circles caused by pigmentation or skin dryness.

The cause of dark circles in tea is closely related to the increase of age. Long-term sun exposure causes pigmentation in the eye area, and over time, it will form dark circles that cannot be swayed.

  In addition, the slow metabolism of melanin caused by blood retention, as well as excessive skin dryness, can also lead to the formation of brown dark circles.

  Fourth, repel the dark conditioning of the daily conditioning side 1, to maintain excess sleep and correct supine sleeping position, better than a variety of care methods.

  2, correct bad eating habits, do not overly salty food and irritating food, do not smoke too much, drink.

  3, timely treatment of chronic diseases, strengthen nutrition, appropriate supplementation of vitamins C, A, E.

  4, acupoint massage black eye is caused by poor blood circulation, acupressure massage helps to open the blood; apply eye massage cream or eye nutrition cream on the skin around the eyes.

  Use the ring finger to press the 瞳孔子髎 (at the end of the eye), the back of the ball (1/3 of the lower eyelid), four white (1/3 inside the lower eyelid), the eye (the inner corner of the inner corner), the fish waist (Eyebrows in the middle), Yingxiang (outside of the nose), each point is blocked after 3-5 seconds of relaxation, and 10 times in a row.

  Use the middle finger and the ring finger (the middle finger is placed on the upper eyelid, the ring finger is placed on the lower eyelid) and gently massage from the inner iliac crest for 10 consecutive times.

Use the index finger, middle finger, ring fingertips to flick the eye, 3 to 5 laps.

  5, mild heat compresses the hot compress to help promote blood circulation, immersed in warm water with a soft cotton towel, wring it out and spread it on the upper eyelid, repeat 2-3 times; the water temperature should not be too hot, because the eyelid skin is very thin, tooThe skin of the skin is loose and wrinkled.

  6, thoroughly remove makeup If you often make up, be sure to use eye-specific liquid lotion to remove eye makeup, especially eyeliner and eyelash parts, do not let cosmetic pigments penetrate into the eyelids, otherwise the eyes look like a black circleIn general, eye-specific cosmetics should be used, and facial cosmetics should not be used.


Blind weight loss vigilance 5 big mistakes

Blind weight loss vigilance 5 big mistakes

Misunderstanding 1: Weight loss = beauty can be determined: weight loss is not equal to beauty.

  It is a pity that there are many girls who have a very poor understanding of their understanding. They think that there is nothing wrong with their body. This is called beauty.

If this is the case, I advise these girls to live in Ethiopia for three months, and they will be able to achieve results. They will not have to go on a diet at home, and they will be dizzy but have no way to get the ideal body.

  If you have biological knowledge, you should understand that all the human body’s scores and this distribution ratio are natural wonders.

Aunt also has an irreplaceable role.

Moreover, with the uncle’s pad, the skin will look smoother and more elastic.

This is why the skinny bones look so pitiful.

In this way, for girls, the place that can embody the charm of women requires a large number of aunts without exception.

Otherwise, no one will admit that a piece of wood that will move is good-looking.

  Therefore, my point is that weight loss should not be reduced to hate all the embarrassment.

  Misunderstanding 2: Needless to say, pure dieting, modern people are very clear that dieting can not exercise the role of weight loss, it will be counterproductive.

  Because the body’s need for food is neuromodulated, it is achieved through basal metabolism.

If the absorption excess is reduced too much, the basal metabolism will be less protective and the energy consumed will be reduced, but it will be useless.

  Moreover, when there is not enough food in the stomach, or the density of the contents changes too much, the stomach will have corresponding reflex activity.

At least part of it, otherwise sputum, or nausea, first of all, the stomach is in a sub-health state, and then naturally it will be ill.

Dieting will have other abnormalities, sometimes bulimia, some anorexia, and thus more serious, absolutely not feasible.

  Misunderstanding 3: Although the high-dose exercise and heavy-duty intensity exercise also has the word “sports”, it is not a good way to lose weight.

  Exercise weight loss has its requirements: small intensity, continuous, can still breathe freely after exercise, talk and laugh, and fatigue will recover quickly.

Some people are eager to lose weight, and once they want to run for a few seconds at a speed of 100 meters, they are lucky without shock.

Slight burning takes time. High-dose exercise does not provide good conditions for light consumption. It only causes thickening of the muscles, excessive heart load, and constant discomfort.

For the general population without exercise prescriptions, it is very likely to hurt themselves, not worth the candle.

  Misunderstanding 4: Weight-loss drugs There are currently no more than one thousand kinds of weight-loss drugs on the market, but there are no ones.

  Weight loss drugs are nothing more than the following: 1.

Appetite-entropy: malnutrition, stomach damage, rebound and possible overeating;

Fiber incorporation produces satiety – discrete: long-term use, the effect has not been confirmed;

Prevent adult intake – anisotropy: It’s hard to say that even the internal body’s nutrient absorption will affect, and what else can’t be done.

  Moreover, weight-loss drugs abuse the buyer’s wallet without exception, causing a “fatal threat.”

If this doesn’t work, you can imagine how much the buyer is suffocating.

Most importantly, I haven’t heard of it yet.

  Misunderstanding 5: Quickly lose weight to check the food conversion table and energy consumption table, you can know that fast weight loss is a fantasy, no possibility, or can be hungry for a week, both fast weight loss and rapid coma.

  Losing weight is really a long-term task in hard areas. The most effective way for this task is to relax your mind, step by step, work and rest, exercise and diet, and use auxiliary sports nutrition. I can’t think of anything else.A good way.
