1. Does the myopia swimming mirror hurt your eyes?

Generally speaking, if it is a qualified myopia goggles, it usually does not hurt the eyes.Because the effect of myopia wearing myopia goggles is basically the same with the time when wearing myopia, as long as you can see the water surface when swimming, you usually do not have a bad impact on swimming enthusiasts.If myopia goggles are poor or the number of myopia goggles does not meet its actual degree, it usually causes certain damage to our eyes.

2. How to choose myopia swimming moster

(1) Clear and broad visual experience

1. Selection

If the degree of the wrong myopia swimming moster, dizziness and vague vision will appear, but the degree of goggles that should be selected is not the actual degree of myopia. Because the refractive index of water is higher than that of air, the degree must be compared to the frame glasses worn by the usual frame glasses wearing it.Low.But how much should I choose?The standard provided by ophthalmology experts is:

The degree of Swimming goggles is equal to the number of myopia plus half of the number of astigmatism, and then minus 50 degrees to 100 degrees.For example, if your myopia is 400 degrees and astigmatism is 0 degrees, then the myopia goggles suitable for you are 300 degrees to 350 degrees.In addition, if the degree of myopia is not consistent, the one with a lower degree is prevailing.

2. Look at the performance of preventing fog

The myopia goggles with good anti -fog properties have strong water vapor absorption capacity. Its anti -fog coating contains hydrophilic chemical components, can absorb more water vapor, and use high -tech to prevent anti -fog layers from preventing anti -fog layers from preventing anti -fog layers.Fall off.

3. Look at the field of vision

Generally, the visual field of large size Swimming goggles is wider, but when choosing, it is necessary to consider the degree of fit with the face. This is the second criterion for choosing the goggles: it is comfortable to wear.

(2) Comfortable comfort that is just right

How to judge this myopia goggles for a long time is really appropriate?There is a small trick when trying to wear. Without a mirror strap, the swimming mirror is attached to the face. If you feel a slight adsorption, it means that the Swimming goggles and faces are good.Whether it is perfectly fit, is the length of the nasal bridge just right?

Coupled with the mirror tape to try, determine whether the tightness of the mirror band makes people comfortable, whether the softness of the loop of the eye socket is just right. If it is too hard, it will cause the pain of the eye Bone.The risk of increased intraocular pressure.

(3) Safe and harmless material

The Skin of the eye is very delicate. The mirror zone and the pads are the most frequent parts of the eye Skin, so the material must be safe and harmless.Most of the professional Swimming goggles of well -known brands attach great importance to this point. It uses safe, environmentally friendly, non -toxic high -grade silicone. In order to allow people to leave the face without leaf marks on the face, it also uses liquid silicone.Essence

Basic swimming Training

1. Water training

First do watering exercises. In the shallow water area, bend over and immerse your head into the water, count silently, and see how long you can hold on.After repeated practice for a period of time, you will no longer be afraid of soaking your head, and the time of holding your breath will gradually extend.You can also do simple walking activities in the shallow water area to slowly adapt to water activities.

2. Drift

One role of learning is to practice balance.Human head is very heavy. As soon as the head is water, the load of the body is even greater. In addition, if you raise your head, your body will naturally sink.

In the shallow water area, stand back against the wall of the pond, bend over, extend your arms forward, buried your head into the water, and then lift a leg to the back of the pool wall, so that the body is flattened forward.Be sure to bury your head into the water so that your body can be flattened.

Try to relax as much as possible, don't be nervous, and gradually realize that water can float your body.After losing speed, the legs will gradually sink, and then slowly stand up.This gradually overcome tension and cultivate hydrophilicity.

3. Pour water in the arm and legs of the legs

After repeated practice several times, I have confidence and feelings about drifting.After the floating sense and balance are established, you can increase the advancement of breaststroke -arms water and legs.For beginners, these actions are very simple, and you don't need to focus too much on this.After you can swim, the quality of movement gradually improves.

swimming physical training method

1. 90 minutes of training time

2. The frequency 2 times a week

3. Division of training methods

4. Specific arrangements for training:

(1) Aerobic training at 30 minutes at a time, the strength is 65-75%of the maximum heart rate, and the method is swimming.

(2) 35 minutes of power training, the action is selected as follows:

Desktop support: 4 minutes, target muscle: abdominal muscle.

swimming: 2 minutes, target muscles: erected spine muscle.

Landscape rolling abdomen: 2 minutes, target muscles: rectus abdominis.

Push the chest in the device: 2 minutes, the target muscle: pectoral muscle, triceps, and bougainvillea.

Pulling forward: 2 minutes, target muscles: latissimus dorsi, biceps.

Sitting on your legs: 2 minutes, target muscles: quadriceps, gluteal muscles, and rope muscles.

Sitting the legs with legs: 2 minutes, target muscle: dopycassus in the thigh.

Note: Each group is 1 minute.

(3) Ten minutes of joint relaxation and fascia relaxation, relax the shoulder joints (one minute on one side), relax the spine (30 times), and relax the hip of the hip (30 seconds on one side), the foam shaft relaxes the loticThe tibial beam (1 minute on one side), the foam axis relaxes the back and waist fascia (1 minute each).

swimming power training method

1. Basic strength

Basic power is the power basis we need to maintain the basic swimming technology. Everything behind the power basis cannot be talked about. There are many basic power training methods. There are many aspects.Or increase the strength with elastic rope.You can also enhance the strength of the lower limbs through Running, frog jump, and other strengths.The upper limb training can be treated up by the bodies, dumbbells, and so on.

2. Special force training

Special force training is mainly for some specific actions during swimming to exercise your muscle strength, carry -weight leg practice, straight -arm rowing exercises, and Russian turntable exercises.The explosive power is the combination of speed and strength when swimming. It is indispensable. Therefore, the training methods I recommend here are as follows. Put the jump, set up a long jump, and throw the ball on the back of the wall.

3. Pirellium training

Endurance training can be intermittent training with the intensity of the game to improve the ability of the body to adapt to the metabolism and the ability to provide energy to improve physical endurance.It is more obvious than the second, so the second training method is more selected.

4. Core muscle group training

For example, push -ups, tablet support, etc. can be used to exercise your core power.

5. Flexible training

Flexible exercises are the same as various stretching exercises in fitness, which can be used as stretching of various muscle joints in the body.If you have conditions to participate in yoga exercises, it is even more perfect.

6. Coordination training

Coordinated training is essential in swimming, but swimming itself is a way to exercise well. Coordinated exercises during swimming training can be jumped with single -legged rope, crawling training, and hand -lipsticking in swimming in swimming.Cooperate with exercises to conduct coordinated training in swimming.

How to carry out swimming training plans

1. Correct mentality and prepare for long -term "Fighting".

2. watch a large number of videos and conduct expression thinking training methods to clearly know what is wrong movement and what is the correct movement.

3. Correct decomposition can lay the correct cooperation tour.

4. Moving your brain, thinking hard, and learning to swim with your brain.

5. Persist in recording the training diary and make progress on the paper.

6. If you have the conditions to ask the coach, listen to the coach's explanation and guidance carefully, and carefully look at the coach's demonstration.When you do nt practice self -study alone, you need to take a lot of selfies and analyze themselves.

swimming training technique

Warm -up skills before swimming

1. Press the legs on the front

This action will greatly help our knees. We generally need to do at least 20 groups of action.

2. Break -up action

This action is to better warm up our waist. Generally, we need to do 10 like this action.

3. Pulling heel

This can stretch our leg ligament muscles. This is also very important, because if the ligament does not warm up, we will not be able to eat it after we get into the water.

4. Warm upper limbs

We need two hands to stretch at the back. This is also the key. When stretching backwards, we need to pay attention to breathing. Generally, we need to do more than 10 groups.

5. Side presses

Minding legs is also very important. When measuring the legs, we need to pay attention not to press too hard. Generally, a group requires more than 10.

6. Warm upwards

First, the left leg or right leg, and then the other group, push in order, generally need to do 20 groups, and then we can swim in water.

1. Multi -deep breathing before formal holding the breath. Each time people breathe, they did not exhale all the air in the lungs in the last time. The oxygen in this part of the air has been used, which is not fresh.He took a deep breath many times before you stuck, completely excluded this part of the gas in vitro, and the inhaled gas that was inhaled again when he was deeply inhaled was completely fresh air.In addition, you can fully expand your lungs in many deep breathing, so that you can inhale more air than usual.

2. After inhaling all the air into the lungs and start to hold your breath, exhale from the lungs from the lungs and leave some gas in the oral cavity.repeatedly.This is to maximize the utilization of oxygen in the air for alveoli to fully contact the air inhaled in the lungs.

3. After the start of the breath, keep the body as quiet as possible. Do not have extra movements, because any movement needs to consume the energy of the human body, which will increase the oxygen demand.

4. By the last stage of holding your breath, when you feel that you reach the limit, don't exhale all the gas of the lungs at once. You can control your slow exhalation as much as possible. This process can let you hold your breath for 10 seconds.

Inflatable skills in water

1. Keep your breath in the water

Squat the side of the hand, the companion, or the coach's hand, so that the head did not enter the water to practice the breath, and stood up after several times, so that it did not need to protect the practice by themselves.The longer the breath time, the better.If the head feels uncomfortable, the exercise should be terminated to avoid damage.

2, exhale in the water

Squat the wall or companion's hand, put your head into the water, and then vomit with your mouth (nose) slowly. It is best to exhale with your nose alone.Stand up slowly after a period of time.The older the breath time is, the better.

3. Rhythm breathing

There are regular, rhythmic breathing, which is basically similar to the water in the water in front: exhale with mouth (nose) in the water. In addition to paying attention to the rhythm, you can cooperate with the movement of both hands.

Breathing practice method

Stand in the water, support the shore/pool wall with both hands, take a deep breath with your mouth, then squat to immerse your head into the water, hold your breath slightly, slowly exhale out with your mouth and nose, and gradually stand up and raise your head.When the water surface, quickly exhale the remaining gas.Then use your mouth to inhale quickly and deeply on the water, repeat multiple times to achieve proficiency.

The number of practitioners in each group should gradually increase, from more than a dozen to dozens of times. The group can stop slightly between the group and the group. After the breathing is basically uniform, do the second group of exercises.Every time you get out of the water, do not turn the water on your face. After all, you can't wipe your face every time when you swim.

Stepping on water

1. "Dog Plane" stepping on water

"Dog planing" means keeping your arms swinging in front of you, and at the same time, your legs are stepping on the water under the water underwater.

Advantages: You can do it without too many "formal skills".

Disadvantages: Very energy -consuming, which means that you can't use this method for a long time in water.

2. "shallow water" method

The so -called "shallow water" means that when you kick back and forth, your arms are expanded to maintain balance.When stepping on the water in this way, pay attention to keep your toes down. At the same time, one leg is kicked forward and the other legs should be kicked backwards, so as to form continuous front and back swinging.

Advantages: arms are liberated, allowing you to do other things when stepping on the water;

Disadvantages: Because you use your legs to float yourself on the water, it will make people very laborious.

3. "Frog" kick

When you kick your legs, you must keep your thighs, lift your feet to both sides, and then put them down.This method is also known as "narrow -thorium".At the beginning, the legs are vertically closer, then the calves are extinguished to the sides of the body, and the starting movements are quickly recovered, which is the "frog" action essential.

Advantages: Compared with "Dog planing" and "shallow water", "frog" does not need to be so tired;

Disadvantages: This method of kicking will allow you to float up and down in the water and cannot float on the surface relatively static.

4.

As the name implies, "paddling" is to move your arms as a paddle.When doing this action, open your arms completely, place them on both sides of the body, and immerse them under the water at the same time.The palm of the hand is inward, and at the same time, the palm is gathered in front of the body. When the palm is about to touch, quickly turn the palm of the palm out, and at the same time move your arms outward to the starting position.Try to finish a round with both hands.

Advantages: free your legs, so that you can combine the paddling movements of other feet at the same time, such as the "shallow water" method.

Disadvantages: You must immerse all parts except your head to the surface.

5. "Return" method

This method is also known as the "eggbeater" method. It requires you to draw circles in one foot in the water when you are in the water, and the other foot is drawn in the direction of the counterclockwise direction.This method is difficult to master, but it can greatly save energy.

Advantages: If you can fully master this method, you can save a lot of physical strength.

Disadvantages: It is very difficult to fully master this method, and a lot of exercises need to be performed during the learning process.

6. "Small helicopter" method

Using the same movements when floating, lying on the back of the back, lying back on the water, and immediately began to draw the circle with both hands, and the legs stepped up and down at the same time.

Advantages: Simple movements, children easy to understand.

Disadvantages: Continuously drawing in your hands will make people feel tired.

Floating technique in water

1. Use your hands and feet

Make sure your body and limbs are vertically upward from the water surface.If you hit your body horizontally and start kicking and paddling with your feet in the water, it is already a swimming movement, and no longer stepping on the water.

2. The head faces up, breathe normally

Keep your head above the water and try to breathe slowly and regularly.Slowing your breathing is to allow you to relax calmly and store your physical strength to step on the water longer.

3. The arm swing in the horizontal direction

If you move your arms up and down, it will drive your body to float up and down, because your arms are connected to your body.The correct method is to move the arm in the horizontal direction, move together with five fingers, draw forward the palms forward, and the palm of the palm backward, so that your upper body will keep up and not sink.

4. Draw your legs or kick your legs back and forth

If you choose your legs to draw a circle underwater, you should not be stiff or stiff at your toes or feet; if you choose to kick your legs back and forth, your toes must be kept down, and the movement of kicking back and forth cannot be interrupted.

5. Lie on the water on the back of the back, and at the same time gently scratch your arms and feet

If you want to rest for a while, you can lie on your back and lie down on the water, but your limbs still need to be continuously padded, but you don't have to scratch and work hard as you step as much as vertically.

6. You can use any floating equipment

A wood, a short paddle, and even a rubber boat, as long as it can float on the water, you can use it.You rely on consuming your physical strength, not external forces, and the less time you don't sink, the longer you can float on the water.

precautions for swimming training

1. Overcoming shy psychology, not afraid of people jokes.

2. Properly strengthen physical flexibility exercise.

3. In addition to paying attention to imitation movements, we should also understand its principles.

4. Soak more water during the learning stage to make the body float from sinking.

5. study difficulties when you drink water often.

Relax after swimming training

After swimming, you need to relax the muscles of the back of the thigh, the inside of the thigh, the calf, the back, and the shoulder

1. Stretch the back muscles of the thigh

Sit on the ground, straighten your legs in front of the body, bend the other leg, the outside of the whole leg is close to the ground, and the straightened legs form a triangle with straight back.Grasp the toes that stretch your legs for 20 minutes. When you touch your toes, you are not allowed to have elastic movements (it doesn't matter if you can't touch the toes).

2. Stretch the inner muscles of the thigh

(1) Sit, the soles of your feet are close to each other, hold your knees outward and as close to the ground as possible. Grab your hands with your ankles with both hands, keep this posture, count 10, relax, and then repeat 3 times.

(2) Sit, straighten your feet in front of the body, keep your back and knees straight, flex forward from the crotch, grab the ankles of your legs from the inside of the legs, keep this posture, feel the inner side of the thighTightened, relaxed, and then repeated.

3. Stretch the calf (back) muscle

Sin down, support the body with both arms and one leg (straightened, toes on the ground), and the other leg is flexed to relax in front of the body.The muscles are tightened, kept tension, count 10, relax, repeat 3 times, and then change another leg for 3 times.

4. Stretching thigh muscles

Lie on your back, raise a leg, grab your thighs and approach the end of the knee, pull it to the chest, keep the other leg straightened and close to the ground, the head cannot leave the ground, keep the posture, count 10, repeat 3 times, and change the legs.

5. Stretching shoulder muscles

(1) Use one hand to grab the elbow of the opposite arm from the outside and back, pull it to the opposite side of the arms, keep the number of postures 10, repeat 3 times, and then stretch the shoulders on the other side.

(2) Holding each other with both hands on the top of the head, the palm of the palm is facing up, the arms are upward, stretching backwards, and keeping it for 15 seconds.

(3) Straighten one arm up, then bend the forearm back to the back of the head, relax, grab the elbow from behind the head with the opposite hand, slowly pull it to the opposite side, and keep it for 15 seconds.

What is the principle of anti -fog swimming moster

The temperature of the water around the goggles is low, and the local temperature of the people in the domestic people is relatively high. The air in the Swimming goggles is easy to condense on the inner wall of the Swimming goggles to form a tiny water (fog) drip.These small fogs reflect the light to make people's eyes blur.Therefore, the swimming mirror anti -fog is to prevent this fog that can not exist steadily.Now the general method is to modify the surface of the Swimming goggles into super -proof water, so that once the little fog is condensed on the surface of the swimming mirror, it will quickly spread to form a water film. Once the water film is formed, the fog will condense on the water film.(Ball) shape to achieve the effect of anti -fog.

How to choose anti -fog mirror

First of all, the softness and fit of the silicone rings are the most important. You must choose a comfortable silicone ring so that you will not leke your eyes when swimming, and you must be enough to fit the face, so that you will not leak in.

Secondly, it is a lens. The material of the lens of the swimming moster is also very particular. It is best to use the material with anti -strike characteristics. In this way, the lens will not be used for a long time, and the underwater vision is still clear.At the same time, it is best to be light, and the effect of anti -water resistance is better.

As for the choice of the back mirror, of course, it is necessary to adjust. It is suitable for the head shape of different people, and the softness is also very important.

The size of the frame directly determines the size of the field of vision.The big frame has a large field of view, but the mirror of the small frame looks more handsome.

Organic anti -fog mirror classification

1. Anti -fog lens

Stop the fog layer by coating micropores.It can be treated with holes in the mirror surface and glass. Anti -fog coating is generally rich in conductive information A to and silicon oxide.Form a super -proof water anti -static antibacterial agent with inferior anti -dirt, anti -fog, and anti -static effects.

2. Electric heating anti -fog lens

The mirror humidity is increased by electricity.There is no fog.In addition, the mist evaporates quickly.There are other types of anti -fog mirrors on the market.

3. Nano composite anti -fog lens

The nano -glass anti -fog mirror film is combined with physical and chemical phase with the glass.Because water cannot form water droplets on the appearance of the base material, the disposed of glass appearance has hydrophilic function.Instead, a uniform water film is formed to achieve the anti -fog effect.

Classification of inorganic anti -fog mirror

1. PVC-resistance wire anti-fog film

The material is: polyvinyl chloride resistance wire.Features of this membrane: Lead salt stabilizers will be added during production, which are toxic, love heat and soft, hard -to -power, crispy, and easy to get aging.A little break, the entire anti -fog film was scrapped.Advantages: good ductility and electrical insulation performance, convenient materials, cheap prices.The overall service life of this membrane is 4-5 years.

2. pet-resistance wire anti-fog film

The material is: polyester resistor wire.The characteristics of this membrane are: pet membrane surface is Smooth, non -toxic and environmentally friendly, heat -resistant, wear -resistant, corrosion -resistant, anti -aging.The overall service life of this membrane is 8-10 years.

3. pet-carbon fiber anti-fog film

The material is: polyester carbon fiber.The characteristics of this membrane are: cumbersome production process, long construction period, high cost.High toughness, tensile resistance, long service life (more than 20 years), surface -shaped heating body, high temperature resistance, and carried oxidation.Multi -line parallel, even if a certain point breaks, does not affect the anti -fog performance of the entire membrane, the temperature can be appropriately adjusted within a certain range, it is not easy to deform and break, and can be reused.Because of the stability performance and high service life of this film, the renovation of high -end hotels is generally selected for this kind of anti -fog film.However, this carbon fiber -proof fog film, because the selection and processing of materials are complicated, the price of carbon fiber -proof foggy film is relatively high.

[Selection of the degree number of short -sighted swimming mirror] How to choose the classification of myopia swimming moster in myopia swimming mirror

How to choose myopia swimming mirror degree

The quality of the swimming glasses is about physical health, and it is more important to myopia goggles.At present, the myopia goggles on the market basically use plastic steel reinforcement treatment and polycarbonate, silicone and other types, and increase the function of waterproof mist and ultraviolet -resistant rays.

The lens of myopia swimming moster is divided into two types: surface microscopy and absolute flat mirror.There is no difference between the style of the surface Microscope and the ordinary swimming glasses. This kind of lens must be affected by a certain refraction underwater. As a result, consumers should pay attention to the operation of a difference.The absolute plane mirror surface is slightly lower than that of the general swimming mirror surface. The advantage of this swimming moster is that there is no different effect in the water due to the refraction.

The choice of these two types of myopia goggles is also different.For example, there is a sable cardia -myopia goggles that belong to the absolute plane mirror. When purchasing, you can directly choose according to your eyes.At present, most of the myopia goggles are mainly surface microscopy. When choosing, consumers should generally consider purchasing 50-100 degrees according to their actual degree.For example, if your myopia is 500 degrees, you should choose a 400 -degree or 450 -degree lens when choosing a swimming moster.

Classification of myopia swimming moster

The first is myopia swimming glasses fixed by the swimmer's myopia.This lens of this myopia swimming moster is exactly the same as ordinary glasses. After the swimmers, including the degree of the swimmers, including astigmatism processing the lens, it is installed in a silicone sealing box.degree.

The second is a separate myopia swimming moster. The principle is to process the frame and the lens separately and assembled, so that the left and right eyes can be different, but it does not include astigmatism. When purchasingThe left and right eyes are selected to be close to the left and right eye swimming components, and then assembled.The market retail price is about 200.

The third is a simpler and more complete integrated myopic swimming glasses, that is, the left and right eye numbers and the frame of the frame are formed. The advantage is that the price is cheap. The disadvantage is that the left and right eye numbers can only be the same, and the workmanship is relatively ordinary.If a friend with a large degree of daily degree is large, it will not be able to adapt to it.

precautions

The degree from 200 degrees to 1000 degrees (a unit per 50 degrees, you choose low). If there is astigmatism, it is recommended to convert the astigmatism number to myopia for selection.The choice of Contact lenses is a principle.

cleaning and maintenance of swimming moster

1. After swimming, wash the swimming mirror with water, and then put it in the swimming mirror box.The advantage of this is to avoid some unexpected damage to the Swimming goggles.

2. When cleaning the goggles, be sure not to use organic solutions, such as alcohol, these organic solutions will cause corrosion of the lens, and the anti -fog effect of the Swimming goggles will be greatly reduced or even disappear.

3. When there is oil on the surface of the swimming moster, choose the neutral when selecting the cleaner, clean it with the fingertips, then rinse it with water, and then prevent it in a cool place.

4. Do not expose the Swimming goggles in the sun, or put it in high -temperature environments such as car trunk and radiator.Because the anti -fog agent of the swimmingoscopy will be damaged due to high temperature or ultraviolet rays, shortening the anti -fog life.

5. The raw materials of the eye masks, nasal bridges, headbands and other accessories of the Swimming goggles are fine glue or plastic. To avoid aging, high temperature environment should also be avoided.

6. When wiping the swimming lens lens, do not use anything to wipe directly to avoid destroying the anti -fog film layer.When the anti -fog effect of the swimming moster is not very good, you can use the swimming mirror anti -fog agent appropriately.

7. In the case of wet goggles, it is best not to put the swimwear, towels and other items together to avoid causing coloring. In addition, do not pull the eye mask casually after use. If there is no need, do not disassemble the parts.

8. Before using the Swimming goggles, the swimming moster can be used with water with water and the anti -fog function can be fully played.

9. It is best not to touch the lens with your fingers, so as not to leave your fingers, or let the oil polluting the lens on your hand.Because the contact with the eyes in the swimming mirror is partially a closed space, wearing it for a long time can easily lead to hypoxia.Therefore, it is recommended to take the swimming lens for a while each time it is used to allow the eyes to replenish fresh air in time.

What are the precautions for swimming moster use

1. Pay attention to check whether the mirror is transparent and whether there is scratches.

2. Check whether the pad (rubber) of the goggles seal.

3. Pay attention to the width of the bridge of the swimming mirror.The width of some Swimming goggles can be adjusted, while others are not possible, so be sure to try it to see if it is appropriate.

4. The quality of the Swimming goggles.If the elasticity and firmness of the band is not good, it is easy to damage, so pay attention to the quality of the band when choosing.The higher the price, the better. If you want to buy the cost better, you can choose a athletes for athletes. It has very good cost performance.
