1. Can golf shoes usually wear?

golf sneakers are usually not available.

The role of golf shoes is to play a role in waterproof and non -slip at the end of the game. If you wear it flat, the texture of the sole will be worn, and then playing will not play a protective role.Of course, if you don't plan to wear it in the end, there is nothing wrong with it.

The shape, material, structure and accessories of golf shoes are different from ordinary shoes.In particular, the sole nails ensure that the golfer stands steadily and feels down -to -earth, which helps walking and non -slip on an uneven road.When choosing golf shoes, pay special attention to whether the screws embedded in the leather under the upper and the bottom of the bottom should be strong. If this screw is damaged, the entire pair of shoes will be scrapped.The starting point of the choice of golf shoes is to fit the feet. Don't be too large or too small. The feet should not be squeezed in the shoes.

Second, the difference between golf shoes and normal sports shoes

golf is a sport that requires quality. You can find that almost everything related to golf has a dedicated equipment. What are the characteristics of golf shoes?Today we will introduce you to the necessity of wearing high -ball shoes.The most important point that is different from other shoes is the soles of the sole. Its existence can ensure "stability", which is also a vital point when playing.

1. Wide -shoe soles to keep balance

As long as you observe a little, you will find that the soles of golf are wider than other shoe.This is because you must keep your standing posture when playing the ball. A good sense of balance can give you a greater opportunity to play a perfect blow.

2. Small shoe nails, promote stability

The standard stable standing position is the key to playing golf, so stable devices are designed among the special sneakers.For uneven and humid stadiums, there is no more stable role than nails.

3, softer, more flexible

Perhaps comfort is the most basic requirement for any pair of shoes.High shoes are no exception. In order to adapt to uneven stadiums and slopes, soft and light high shoes are even more irreplaceable.

4. You can breathe before you are comfortable

If you make 18 holes in normally, then it is equivalent to traveling throughout the stadium, at least 4 miles.The good breathability and waterproof function of the sneakers can help you maintain the best state at all times and play the best level.

5. Very high -end, very fashionable

golf sneakers have a strong sense of design, from color matching to the overall shape.You can choose to make your taste more outstanding than Yinlefen's products.

1. When did the Swimming ring invented?

In the past, some people thought that the lifeblonga was introduced into China from Europe and the United States. In fact, the lifeburn circle was created and invented by our Chinese.

As early as two or three thousand years ago, my country had a "life -saving circle", which was the dry gourd.At that time, the clever Chinese people found that holding the dry gourd melon can float the body on the water and drown the gourd melon to become the most primitive life -saving equipment.Later, most of the vessels sailing at sea brought gourds to prevent unexpected.It can be seen that the ancient people of my country used the dry gourd to cross the river. This is the most primitive lifebuilding circle.

In the song Dynasty, the production method of the lifeburn was a step forward. Some people began to use soft wood, reeds, etc. to be prepared into a ring object, so that people can drill in and make the ring supporting people.The gourd melon is much more convenient, and it has become a veritable life -saving "circle".Han Shizhong, who was anti -Golden, who was anti -golden hero Yue Fei at the same time, sent Wang Quan to Jinshan to fight against the enemy. Before leaving, Han Shizhong ordered him not to use the boat to cross the river, so as not to be found by the enemy.So Wang Quan sent a circular floating ring made of cork to each soldier, allowing them to restrain the floating ring on the waist and cross the river.The soldiers quietly crossed the river under the leadership of the royal power.At that time, the floating ring used by the royal power was the predecessor of the modern lifebing circle.From the time to modern times, with the application of new technologies and new materials, various life -saving equipment appeared: lifeboats, life jackets, and uniform.But the traditional equipment of the lifebuilding circle is still retained by people, and it is still the easiest life -saving Tool.

2. What materials are the swimming rings made

The material of the inflatable Swimming ring is relatively single. Most of them are made of ordinary PVC materials. Most of the domestic PVC materials are the main in China. The 6P environmental PVC is better.

3. What material is the best material in the life circle

At present, the main forms of domestic Lifeline products include polystyrene packaging cloth life rings, polyurethane polyethylene composite lifebladder, and knot -type polyethylene lifebirth circle.

1. Polyetstics packaged cloth life ring

The polystyrene cloth life ring is mostly used in the inland rivers. The rim core material of the life ring is made of polystyrene material.Generally, the production process is to wrap glass fiber cloth in the rotary core material, and apply 3 layers of phenolic resin to form a sealed glass steel shell, and then wrap and apply several layers of paint.

2. Polyethylene compound lifebuilding circle

Polyethylene composite lifebrows are used as high -density polyethylene materials as shells. The internal rechargement of polyurethane foam materials is a new type of lifebuilding in China.At present, more than 100,000 annual output has reached more than 100.The composite life ring solves the problems of oil -resistant oil tolerance of polystyrene bales, in high temperature environments and long -term radiation in ultraviolet radiation, which is prone to aging, paint layer peeling, and complex manufacturing process.This type of lifebuilding has the advantages of solid color, Smooth surface, anti -aging, large mechanical strength, and corrosion resistance, but production costs are higher than that of polyethylene Bags.

3. Knotchye polyethylene foam life ring

The polyethylene lifebuilding circle is also known as the citrine polyethylene foam lifebuilding circle. It is made of low -density polyethylene foam. It is a new technology product. At present, only a few companies in China can produce.The circle of its products is only made of a single material of polyethylene. The circle body is full of elasticity. The surface is bright and beautiful on the surface. The strength, buoyancy, oil resistance and erosion resistance are not comparable.At present, the domestic product has high technology and high costs. The products produced only supply military or exports.

1. What is the principle of color change Cycling glasses

Trimous glasses can change the color of the lens according to the strength of the external light, thereby protecting the eyes from strong light stimulation. Therefore, many friends choose to wear colorful glasses when riding, but many friends do not know the principle of color change Cycling glasses.The working principle is simple:

1. When making color -changing Cycling glasses, the light color material is added to the glass raw material. The lens contains silver (silver chloride, silver bromide) microcrystalline.Electronics, the electrons are captured by silver ions and reacts: colorless silver is decomposed into opaque silver atoms and transparent halogen atoms. The silver atom absorb light to reduce the light transmission rate of the lens, so the color of the glasses changes.

2. Because the halogen in the color changing lens is not lost, the reversible reaction can occur. After the activation of the light disappears, the silver and the halogen are reused to restore the lens to the original transparent colorless or light -colored state.

riding is often outdoors and needs to be stimulated by the sun. Therefore, it is better to wear a pair of discolored Cycling glasses. However, some friends are worried that the color changing Cycling glasses will be harmful to the eyes.Intersection

2. Is riding colorful glasses harmful to the eyes?

The light transmission rate of color -changing Cycling glasses is relatively low. Although it can absorb most of the ultraviolet, infrared rays, and various harmful glare, due to the halogen chemical components contained in the lens, the light transmission rate of the lens is relatively poor. If it is used for a long time, it is used for a long time.It may cause visual fatigue and not suitable for long -term cycling.However, with the advancement of manufacturing technology, the discoloration rate and fading rate of color -changing lenses have greatly improved, and high -quality color -changing Cycling glasses almost have no harm.

In addition, it should be noted that there are some inferior color -changing Cycling glasses unevenly discolored, either slow color change, fast fading, or fast discoloration and slow fading, and some even do not change color at all. This Riding glasses can not be worn for a long time.For effective eye protection, you should pay attention to buying two lenses when you buy.

The difference between the double -layer Tent and a single Tent

1. Different manufacturing process

Single -layer Tent production process is relatively simple.

The double -layer Tent adds a layer of breathable internal account on the basis of the design of a single -layer Tent.waterproof and windproof, breathable internal accounts; the heat emitted by the human body will be condensed on the inner wall of the external account through the inner account, and then follows the inner wall of the external account to slide to the gap between the outer Tent and the inner account.sleeping bag.

2. Different volume operations

Single -layer tents are lightweight, small in size, small area, and easy to build.

The double -layer Tent is large, and there is a lot of space to occupy it. It covers a large area and is tedious.

3. Different use environment

Single -layer tents are mainly used for summer Camping activities such as Park leisure and beach leisure. Generally, it is not outdoors overnight, and the price is relatively cheap.

Double tents are generally used for Outdoor wild camps overnight. Because of the light weight, it is also used for snow mountain climbing, but it is necessary to use high -tech Functional fabrics and auxiliary materials, which are more expensive.

4. How to choose

Because in a cool season, the heat excluded by the human body will be condensed in the inner wall of the Tent under the influence of the air outside the Tent.Internal accounts are connected, and the heat emitted by the human body can pass through the inner accounts, and the water droplets that are condensed in the outer Tent can be flowing on the ground.Therefore, the general environmental temperature is more suitable for using a single -layer Tent when it is 5 C. When the ambient temperature is lower than 5 C, because the inner wall of the Tent will be cooked, it is best to use a double -layer Tent or a three -layer Tent.

The advantages of double -layer tents

Everyone knows the place where the Tent provides people when it is camped. Everyone knows that the temperature at night will be reduced, so the first Tent can keep it warm.Because of the temperature difference between day and night, the humidity at night will be very heavy, and the Tent should prevent moisture from being soaked.Especially in the mountains and forests, the fog is particularly heavy in the morning and evening, and the water vapor outside the Tent is severely condensed. If the fabric cannot be waterproof, small water droplets will be leaked in the Tent, and the environment is cold and wet, which cannot provide people with good rest places.

Because of the two requirements for tents above, single -layer tents cannot adapt to Camping.Although the single -layer Tent is also made of thick and waterproof Oxford cloth, there is only one layer. It cannot be kept warm and waterproof. It can not be adapted to rain.The double -layer tents are different. Its design is divided into two layers of external accounts and internal accounts. There is a space separated between the two layers.The external accounts block the wind and rain, and keep the internal account warm and dry. Whether it is raining or snowing, it can give travelers a peaceful place.In addition, the external accounts and internal accounts of the double Tent can be used separately. When the sun is large during the day, it can be opened alone, which becomes a gazehop.

How to put it in a double -layer Tent

1. Before building a Tent, you must first choose the right camp. Generally, you choose to stay away from the river.

2. First take out the Tent's foreign account and internal account when setting up. You can first set up an internal account, or you can set up the foreign account and then get into the internal account.Put one of them on the ground according to your own habits.

3. After the inner account is paved, remove the nail Bags, poles and other accessories.First handle the Tent pole, connect the Tent rods one by one, and the connection should be tightly tightened to make two long rods of equal length.

4. The pipelines of the Tent bolt on the internal account will pass the two long rods through the relative two pipes.Two long rods should be worn at the same time. The long rod will be arched up because of the Tent structure, and the Tent will be opened as a result.This process requires at least two people. It will be more convenient to operate by four people.When wearing a pipeline, wear the corner of the Tent to the bottom corner, do not wear a loop.The Tent supports the two ends of the long rod to the ring at the bottom of the corner, and the entire inner account will be fixed.

5. After the internal account is done, you can hang the foreign account. The method is to open the external account and cover it on the inner account.The windproof rope is designed on the external account. After pulling the rope straight, it is fixed with the windproof hook. One can strengthen the stability of the Tent, and the wind will not overturn the Tent.The two layers of tents are more powerful and warm and humidifying.

1. Basic Running basic skills training

1, Return to run

The distance to restore Running is relatively short, Running with the easiest pace.It can be used as a warm -up or relaxation.Restoring will not affect the performance of the main training tasks after you. Its role is to make you accumulate a little bit of Running.And in intermittent training, after you sprint and run, you have to take a recovery.The key to restoring Running is slow and comfortable, and will not let the previous fatigue affect your later training.

2Foundation

The distance of the foundation runs medium, just run in general pace.Basic Running is not to increase difficulty, but to allow you to increase the number of daily exercise, it can effectively stimulate your aerobic ability.It is your most proportion of your weekly training.

3run long distance

Long -distance Running is also a foundation, but it is because the distance is longer and the fatigue of medium or above.The purpose of long -distance Running is to increase your endurance and realize the distance or duration required for this effect, depending on your current level of endurance.Increasing the confidence of the endurance project competition, your endurance will not become an obstacle to the end.In long distances, you can also play some tricks.

4, Graduate Running

It is to gradually speed up the pace. You will jog from the beginning, and then reach your marathon. In the final stage, you may use you10Krun the game.The difficulty of Running is moderate, it is more difficult than the foundation, but it is easier than the threshold and intermittent Running. Its strength is moderate, and the recovery time after training is also short.

5Speed intermittent

fartlekIn Swedish, it means "Speedplay"It is composed of the basic Running and the interval of different times or distance. Compared with the intermittent Running threshold Running as a high -level training,fartlekMore is a adjustment in the training cycle.In the early stage of training, it can promote your Running economy and improve your ability to resist fatigue; in the later stage of training, it can allow you to increase the speed.In the training of the venue,fartlekIt can also be used as a good supplement to traditional intermittently.

6, run uphill uphill

Repeated Running uphill is composed of multiple uphill Running.Improve aerobic capacity, high -intensity anti -fatigue ability, pain tolerance, and the power of Running muscle groups.The terrain slope that can be used for uphill Running is generally4%arrive6%between.Generally, you need to arrange it after full warm -up.It can be said that it is the most unprecedented training method. Although it can be practiced and long -term, you have to find a suitable slope to run.

7, run the threshold

A kind of training that keeps you in the heart rate interval of lactic acid threshold. Trained runners can generally persist for an hour under this pace, and the weaker runner can insist on this pace.20minute.The purpose is to improve your long -term pace and extend the fast pace to bear time.

8Intermittent Running

Mot your short -distance fast Running plus jog recovery or in place recovery.Compared to letting you run your best, you will be exhausted. The intermittent Running method allows you to run more fast Running in a training.Intermittent Running is usually divided into short and long interval, and they are all performed in the venue.

Second, long -distance Running physical training method

1Increasing the power of the upper arm can be practiced through simple push -ups.Do not need to be too fast when you do push -ups, and pay attention to the width of your arms to strengthen the strength of the back, shoulders, and arms. All these parts will play an important role in the final stage of the long -distance Running.Don't do too much at once, just start doing it4Time5The second time, then the number of times gradually increases with the increase of strength.The advantage of doing push -ups is to provide resistance with your own weight.3No need to invest in any facilities.

2, Plan and regularly sit up.This exercise will exercise the back, waist, and abdominal muscles.Incorporating the upper body power into your daily Running, the simple method is to do it like a organic movement after Running every day.Do it at the beginning10Sitting up, sitting up,5Push -ups and20The second arms flexion and stretch, increased after two weeks12Sitting up, sitting up,6Push -ups andtwenty fourA flexion and extension.

3. How to carry out long -distance Running training plans

1run a few days a few days a week.

2, Use some low -intensity training per week to replace1Day or2God's Running.For example, aerobic and sweating training on power bicycles.

32. Incorporate some walking activities into your training

4The game should be a little less.

5When you are preparing to maintain physical fitness without the task of the game, you should try to reduce the amount of exercise, maintain your results and insist on reducing the amount of training.

6In -depth organizational massage in a planned manner.

Fourth, long -distance Running training skills

1Double muscle training

If we want to improve the level of Running, then muscle training is essential. The muscles are equivalent to the engine in exercise. The engine is not good. We are not Running in the long run!

First of all, we can run uphill or resistance. These two training can greatly increase muscle endurance and explosive power!In fact, we should also start with our muscles, use high legs, and squat to strengthen our muscles!

2Nutrition allows muscles to restore

If we just do not pay attention to diet, then our Running progress is also very slow!The body will be damaged during the exercise process, and sufficient nutrition can repair the body, which can ensure that our body is getting stronger and stronger!

If you do nt eat it, your physical fitness will decrease, the whole body will be exhausted, and the whole person will be mentally sluggish. If you want to improve quickly, then we must learn to supplement sufficient nutrition!

3, Composite training

When we run, we should choose more and diverse training methods!If we can only jog at every day, then the bottleneck of our Running is difficult to break, and we weaker and weaker, the more we are Running, the more and the slower.

After Running slowly, we can spend five minutes for sprint Running training, sprint100rice rest,100rice sprint100Mi rests a hundred meters, and you can practice five to six times back and forth!This is very helpful to improve the speed and performance of long -distance Running.

5. precautions for long -distance Running training

1Of course, long -distance Running is to pay attention to water, so long -distance Running should pay attention to replenishing enough water, so as to ensure that you do not dewater when you run.

2, Leg exercise, if you run for a long time, pay attention to the exercise of the knee and ankle joint. Because of long -term Running, the knee and ankle joints are relatively large, so properly relax when doing exercise.

3, Cardiopulmonary function, if you do not run often, then cardiopulmonary function is not very good. At this time, you have to connect cardiopulmonary function, such as the form of Duoduo up and down stairs.

4, Pirellium training, long -distance Running, you must conduct good endurance training. You can extend your length you want to run, such as3kilometer,5kilometer,8This extended training such as kilometers can achieve the goal well.

5, Nutrition match, when you exercise a lot, the nutrition in the body will accelerate the loss. At this time, pay attention to the balanced diet.If you don't lose weight, you can eat more meat properly. If you want to lose weight, eat more protein.

62. Supplement of salt. When the long -distance Running passes, the salt section of the body is more serious. At this time, drinking some salt water can replenish salt and replenish energy.

7The lifting movement, whether it is long -distance Running or ending.The stretching and relaxation exercise must not be less, which can reduce the pain caused by long -distance Running.

6. Relax after long -distance Running training

1Relax of muscle groups on the back of the calf

The calf rear muscle group (than the fisheyle muscle, the gastrocnemiosus) relaxes, the foam shaft is placed on the calf13The position of Zusanli, the hand can45You can also support it ahead.Get rolled to the position of the knee nest and came back to the top side of the ankle.

2, Relax of muscle groups on the back of the thigh

From the top of the knee, the four -headed muscle of the stock, rolling to the lower edge of the buttocks.Adjusting the position of the support hand can increase the amplitude.Note all the power to add to the leg you relaxed.

3, Relaxation of the tibia of the calf

Kneel on the foam axis and roll to the upper side of the ankle joint. Note that it is easy to put the strength on the tibia.

4, Relax of the quadriceps of thigh stock

Because the load required for the quadriceps of the thigh stock is very heavy, everyone knows that it is such a large muscle group on the upper side of the knee, so in the process of Running, especially in the process of Running the mountain, the quadriceps muscle must be done.Many, let's take a look at a lot of excellent runners. The volume and volume and lines of thigh stocks are very large.

5, Relax

The iliac tibial beam is the deep fascia around the thighStidal part of the outer side of the wide fascia.The outer edge of the iconic part,,It is divided into two layers,,Wrap wide fascia tension,,And closely combined with it should not be separatedThen, thenThe vertical fiber in the lower part is significantly thickened and flat -shaped,,The rear reed of the gluteal muscle tendon continuesThen, thenThe lower end of the tibial tibia is attached to the outer tibia, fibula head and knee capsule.Clinically, the iliac tibial beam is often used as a repair and reconstruction material for the repairs and reconstruction of the body wall defect, weak parts or knee cross -ligament damage.

6Relax of upper and lower back

If you are uncomfortable on the top, the lower back feels uncomfortable, for example, many people have the posture of pot and waist when they are Running. After a long distance, the whole shoulder is unwell, or many Desks work more.The neck and spine are helpful.
