1. How much is the price of gliding umbrella

Global umbrella is a very exciting sport. Many friends who want to learn gliding umbrella are more concerned about the price of gliding umbrellas. So how much does a set of gliding umbrellas cost?

A basic glide umbrella equipment includes a large number of umbrella heads, Bags, auxiliary umbrellas, helmets, and intercom. If the supporting facilities are complete, you also need to buy umbrella Bags, flight boots, flight computers, etc.A set of 30,000 to 50,000 yuan.

Generally speaking, the price of gliding umbrellas is mainly related to the level and brand. The prices of the same level and different brands of umbrellas will not be too large.At different Levels of umbrellas, as the umbrella wing level increases, the price of the umbrella wing will increase.(The above price source network is for reference only)

2. Why the price of gliding umbrella is so expensive

The price of gliding umbrellas is relatively expensive. Many friends think that the structure of the gliding umbrella is simple, the material is not complicated, and the price should not be so expensive. In fact, the sliding umbrella is expensive for a reason.

The gliding umbrella is a niche movement. From R & D, design, production, test flight, and distribution, it is designed to multiple Links. The cost is relatively high; in addition, there are almost no gliding umbrella brands in China, and 80%of the gliding umbrella brand is earlier in Europe.Coupled with freight, tariffs, etc., the price of gliding umbrellas is added.

To sum up, the gliding umbrella is more expensive, but now many clubs provide umbrella tools during the course study, and can be used in the later period.Buy gliding umbrella.

3. How do beginners choose a gliding umbrella that suits them

Beginners choose gliding umbrellas, usually mainly look at the word of mouth, the amount of preservation, and color matching. According to the recommendation of the coach or friends, it is also skillful to choose a gliding umbrella. You can choose from the following aspects:

1. Plane area

That is, the plane area after the wing surface is flat. The larger the plane area, the larger the pilot's weight range. When choosing, you must choose the umbrella head size that matches his weight.It is generally recommended that new students can choose to be close to the umbrella flying weight in the middle limit to increase flight stability.

2. Plane wing show

That is, the longest distance from the wing tip to the other wing tip. The relationship between the length and the plane area of the plane wing exhibition and the plane area largely determines the safety and flying performance of the umbrella. The larger the string ratio, the higher the flight performance, and the ratio of the string ratio.The smaller, the higher the safety performance; the novice of the gliding umbrella enters the primary flight. Before you have not fully mastered the flight skills and accumulate the flying experience, it is recommended to choose a relatively small umbrella more than a string to build a flight confidence.

3. Projection area

After the umbrella head is completely inflated, the shadow area of the umbrella head obtained directly from the light is theoretically. In theory, the larger the ratio of the projection area and the plane area under a certain situation of the plane area, the greater the lift.

4. Projector exhibition

After the umbrella head is completely inflated and open, the straight line distance between the wing tip is, the smaller the ratio of the projection wing exhibition and the plane wingspan, the greater the arch.The small umbrella is high. Among different umbrellas, if the plane string is the same, the larger than the values of the project festival, the better the flight performance theoretically.

5. Guidance

The conventional umbrella head has two layers of upper and lower layers, and a hollow structure is formed in the middle. It is called the gas chamber. The wing ribs vertically on the umbrella surface in the gas chamber are divided into many small gas chamber. In the same area, the gas room, the gas room,The more, the better the umbrella.Therefore, at the same price, the more gas rooms, the better.

6. Umbrella head weight

Light gliding umbrellas generally use lighter materials, and contain superb design skills, which means easier flight, faster wings recovery performance, better flight performance, and standard umbrellas using standard materials.Within the scope of the head, you should give priority to the lighter umbrella head.

7. Certification level

The EN standards of the EU Standardized Commissioner are generally used as certification procedures and umbrella-level evaluation. The gliding umbrella certification is the EN-926 instruction, the bag is certified by the EN-1651 instruction, and the life umbrella certification is the EN-12491 instruction.The helmet protection certification is the EN-966 instruction, pay attention to the certification level.

1. Where can I generally sell fingerprints?

The finger cover is a sports gear used to protect the fingers, also known as the nursing finger. It is mainly used by basketball players. It is one of the essential sports equipment for basketball players.Buy the finger, where can I sell it?

As a sports gear, if you want to buy fingerprints, you can buy it at a sports store. Some large shopping mall supermarkets can also be bought sometimes, usually with basketball.If you are inconvenient to buy offline, you can also choose to buy online. Now it is also convenient to buy a nursing index on online e -commerce platforms.

2. How much is a finger?

When playing basketball, pay attention to protecting your fingers. A lot of friends who pay attention to wear fingers will wear fingers. Professional basketball players wear nursing fingers usually two are connected together.The factors have different influences. A pair of cheap is about 5-10 yuan, and the expensive ones are from 450 yuan to hundreds of yuan.

Note:The above information source network is for reference only.More finger protection reference & gt; & gt;

3. How to choose a good protective cover

The nursing finger is a basketball protective that protects the fingers without sprains. Good finger can give fingers better protection. So how to choose a nursing nursing?

1. When choosing a nursing finger, it mainly depends on the two aspects of the finger protection model and fabric. Generally, you must choose the finger protection suitable for your finger model. In terms of fabrics, it is generally recommended to choose a pure cotton or nylon knitted fabric.should.

2. After all, the finger is worn on the hand to protect the fingers, so try to buy it by yourself when you buy it. This can wear your hand to try it. It feels comfortable, the strength and tightness are appropriate. It does not affect the finger activity.

How about rubber foam shoes?

The rubber foam base is a paved fabric made of naturally or artificial rubber -made rubber -closing or open -hole foaming materials.Half a century ago, people used this material for a large amount of such materials for sneakers, sports shoes, tourist shoes, liberated shoes, casual shoes, etc.

The bottom of the shoe made of rubber foam is light and wear -resistant, good tearing resistance, aging resistance, corrosion resistance, and insulation.20 The low temperature of the degree will not occur. The performance of the rubber foam sole is much better than the foam plastic outsole, and the production process is simple.Use foaming materials as the sole to reduce the weight of the shoes, increase the elasticity of the sole, make it more abrasion and more comfortable to wear.

Is rubber foaming sole wear -resistant and non -slip?

The advantage of foam rubber soles is that the weight is light and soft, and the built -in foam base also has a warm function.The non -slip performance is mainly related to the pattern of the material and the sole. For example, people call itThe bottom of the "beef tendon" is poor on the snow and ice.The non -slip performance is better on the mud.The tooth -shaped bottom drainability is better. The non -slip performance on the wetland is good ,, The suction cup pattern bottom is good at ice and snow.

Comparison of rubber base, foam base and rubber foam base

The proportion of rubber bottoms is generally high (that is, unit density) is a sulfide process, but non -slip and wear -resistant is the first choice for shoe materials (except for novel composite materials). It is suitable for Outdoor shoes, running shoes, basketball shoes, etc.

The foam base is a foam process. The mainstream of the current industry is used EVA Foam, which will be lighter than other materials, but the cost is that other material properties do not have rubber bottoms. Generally, it is matched with rubber.

The rubber foam base is based on the rubber base and the foam base. It is a rubber foam function (we know, if the rubber is 1 Compare 1 If, rubber foam is generally 1 Compare 1.1 It can be done). The advantage is that it has both the high -wear resistance characteristics of the rubber and the lightness of the foam base than the traditional rubber.It is also obvious that processing operations are difficult.Generally, you can replace the rubber bottom with foaming EVA The bottom is matched with the bottom.

In simple terms, Rubber bubble bottom Good.Because the soles must first consider comfort, foaming can be successfully improved to improve the shock resistance and vibration reduction performance of the sole.

Without foaming, because of its good return of elasticity, the comfort of rubber is stronger than that of ordinary plastic, and the abrasion resistance is also stronger, but the periponum resistance is weaker.Both plastic and rubber can be foamed, and because of the continuous development of plastic technology, the boundary between rubber and plastic is not so obvious.In terms of process costs and comprehensive performance, important members of the plastic family--- Thermoplastic elastic body is increasingly low to replace rubber.

Definition of control knives

The control knife, according to the "Devil Dawn tools," refers to the dagger, triangular knife, spring knife (jumping knife) and other similar single -edged, double -edged, and triangular tip knives.According to the provisions of Article 2 to 7 of the Ministry of Public security's "Interim Provisions on the Implementation of some tools", there are legal procedures for controlling the scope of the wisdom and production, purchase and sales of the control of the tools.

2. Factory and workshops that manufacture control knives, must be reviewed and approved by the competent authorities at or above the county and the county and municipal public security bureaus, and issued the "Special knife Production License", which is allowed to produce;Specifications, models, uses, quantities) must be sent to the county and municipal public security bureaus to record.

3. shops that distribute the above -mentioned control knives must be reviewed and approved by the county and cities.The registration system must be established and prepared for the public security bureau for inspection.

4. Units and individuals who purchase control knives apply to the county, the Municipal Public security Bureau (Public security Branch) of the local county and the Municipal Public security Bureau (Public security Branch) to buy the "Special knife Purchasing Certificate" to purchase;The letter is ordered to order from the designated unit; the triangular scraper is purchased from the store approved by the unit to the store.

5. Tibetan knives, waist knives, boots, etc. used by ethnic minorities, are only allowed to be sold in national autonomy.

Standards for controlling tools

1. Anyone who meets one of the following standards can be identified as a control knife:

1. Dagger: with a single blade, double -edged or multi -blade tip knife with a knife handle, blade, and blood grooves.

2. Three -edge scraper: The Tool processing with three blades with three blades.

Was the kitchen knife counting the control knife

It can be said that the kitchen knife is both a control Tool and not a control Tool. This is because the kitchen knife is a general concept.There are various types and styles of kitchen knives. Some are regulated according to the standards, while some are not.The criteria they apply are:

The angle of the knife tip is less than 60 degrees, and the knife body is more than 150 mm.

The angle of the knife tip is greater than 60 degrees, and the knife body is more than 220 mm.

In other words, the most common Square kitchen knife in us must not belong to the control knife, and it generally exceeds the length (such as the large watermelon knife) even if the control knife is controlled.

Summary: Strictly speaking, most people have control knives, and the larger kitchen knife is a control knife.Do not carry it frequently to avoid carrying it in public.

1. The role of compressing socks

1. The earliest compression socks used in the field of treatment

Compressed socks (medical) were used in patients with chronic intravenous incomplete patients as early as decades ago. By above the bottom, from the bottom to the top, the vein blood flow was improved from large to small gradient pressure, reducing lower limb swelling and thrombosis.So what is the principle?

As we all know, the heart promotes the blood flow of the whole body. When the blood flows through the arteries and capillary, the power has been obviously attenuated, and the lower limb vein blood flows back to the heart to overcome gravity.Will venous blood flow back? Hey, the human body is amazing, and the existence of double valve valves in venous blood vessels usually exists. When from bottom to top flow, the valve is attached to the wall of the blood vessels and will not cause obstacles. Once standing standing, once standingOr when the venous pressure increases by other reasons, the two valves will be opened to prevent the venous blood from flowing.

However, if you stand for a long time or sit for too long, the blood veins of the calf are stagnant, and you will feel swollen and numb.Patients with chronic intravenous dysfunction usually have symptoms such as lower limb blood flow and valve dysfunction. It is common to be venous. At this time, a pressure from bottom to top can promote the return of venous blood.A positive pressure helps to improve the function of the valve, which is the function of compressing socks.Therefore, the most important role of compressed socks in medical treatment is to promote venous return and prevent deep venous thrombosis.

Medical compressing socks have confirmed that patients have been confirmed. So, is it possible to increase runners' sports performance, improve Running performance, and promote recovery like major manufacturers promoted.

2. Can compressing socks improve the results?

In theoretical analysis, wearing compressed socks (sports) during the Running process, the entire calf muscles are wrapped in stress pressure of the socks, which will help vein blood to return to the heart faster, and at the same time increase the blood flow rate of the calf vein.The acceleration of venous blood flow means that the more blood ejected at each time the heart is, the passiveness of the athletes keeps in a high -intensity state, and it looks logical.

However, experimental data does not support this statement. In some studies, the marathon runners are usually selected, and the experimental distance is usually controlled within 15km.After the experiment, a considerable part of these marathon runners did not feel deep fatigue like when they were not wearing compressed socks. Therefore, the debate about whether compressing socks increased the Running results.

Researchers at Newcastle University found that compressing socks did increase the blood flow of lower limbs and reduce heart rate during high -intensity endurance exercise. However, this study also found that even if this, compressing socks did not allow the subjects to improve their Running results.Other studies have also found that compressing socks have not increased the results of 10 kilometers.There may be two reasons for the result of such contradictions: compressing socks can indeed improve the ability of exercise, but it can be ignored by increasing the size. The second reason is that the compressed sock itself has a certain weight (about 85 grams). This weight offsets the weight.The exercise benefits brought by compressed socks are basically close to the weight of lightweight running shoes.

Another Malaysian experiment of compressed socks, let's look at the results of the experiment: Researchers divide 34 experienced marathon athletes into two groups, one group wearing compressed socks, and the other group wearing normal socks to run throughout the marathon.Their Running speed, jumping height, and calves are not significantly different.

3. Can compressing socks relieve muscle soreness?

Judging from the aforementioned results, whether compressed socks can improve exercise capabilities, so does compression socks alleviate muscle fatigue?Taking the full marathon as an example, each runner must run at least 30,000 steps to run the whole process. In the process, the impact of the ground on the ground will cause the musclesAn important reason for fatigue.The compressed effect of compressing socks reduces the calf muscles to reduce the depression during the Running process, and can reduce the degree of muscle fatigue to a certain extent. At the same time, this external surround pressure also reduces the wearer's feeling of pain.More Smooth and natural.

Researchers at Massey University found that compressed socks can reduce delay muscle soreness that occur after fast Running (so -called delayed muscle soreness refers to muscle soreness that occurs 24 to 48 hours after Running).After 10 kilometers after the dramatic discovery, 93%of the runners who did not wear compressed socks, 93%of them had delayed muscle soreness, and only 14%of runners wearing compressed socks had the same soreness.

4. Can compressing socks promote recovery after Running?

Putting on compressed socks after exercise, theoretically analysis can help the metabolic waste cleared in time by promoting blood circulation, which is also conducive to muscle regeneration and repair.Studies have stated that athletes have extended 6%for athletes to wear compressed socks 48h after wearing compressed socks 48h than compressed socks.Researchers at EXETER University first let volunteers practice continuous vertical jump in order to allow volunteers to produce obvious muscle fatigue and delayed muscle soreness, and then let the volunteers on the first day, the second day, the third day, and the third day and the third day and the third day.On the fourth day, 3 kinds of leg strength exercises were performed to observe whether the exercise performance decreased during the exercise of leg strength and delayed muscle soreness. It was found that after wearing compressed socks for 24 hours, the exercise performance of the leg strength exercise was phased.It is improved than not wearing compressed socks, and muscle sourness can also be reduced.

However, some studies have found that wearing compressed socks cannot alleviate delay muscle soreness caused by marathon games.

Therefore, in general, compressing socks are not as magical as improving Running results, but it may have a certain effect on reducing muscle soreness and promoting fatigue recovery.Of course, according to the editor, the recovery methods such as warm -up and stretching massage after Running and the stretching massage after Running can also be generally achieved similar effects.Therefore, if compressing socks can improve personal PB during use or have effective effects on relieving fatigue, then use it during Running.It doesn't matter if you feel that compressing socks are too tight, uncomfortable to wear.

5. Summary

After evidence, overall shows that compressing socks are not enough to improve Running ability and Running performance, but compressing socks may have a certain effect of alleviating muscle soreness and promoting recovery, but the effect is not unanimously affirmed.

two,Can compressing socks lose weight?

After putting on a compressed socks, it seems that the calf is indeed thinner. This is because the human tissue is elastic. After being compressed by external forces, the natural volume becomes smaller, but does this mean that the calf will become thinner?Of course not.Because human tissue is elastic, when the compressed socks are taken off, the calf will still become the original shape.It is impossible to change the calf shape for a long time by relying on a little external compression force. To make the calf thinner, there is only one way to consume the fat of the calf through exercise.If you can wear a compressed socks, you can wear a Compressed jacket, thin arms, thin belly, thin thighs, and thin thighs. This is obviously impossible. Wearing compressing socks makes the calf look thinner and really make the calves change.slimming is completely different. Compressing socks do not have the mechanism of thinning the calf.

Therefore, many people wear compressed socks and feel that the calves are beautiful, but this does not mean that the calf can really lose weight after putting on the reducing socks. If it really becomes thinner, it is also the effect of exercise, not the effect of compressing socks.
