1. What are the cooperation of Underwater propeller and what to use

If you are interested in diving in shipwreck, the Underwater propeller will definitely help you, because the shipwreck is usually very large, it is difficult to see that it is difficult to see.But it's not to say that with it, it will be almighty. Let's take a look togetherUnderwater propellerUse what to cooperate!

Underwater pusher is generally used with oxygen cylinders.

Submarine sea travel must wear oxygen cylinders. The oxygen cylinders of the submerged sea will not be pinched to the seawater. The oxygen cylinder will have a pipeline that transports oxygen. The oxygen is directly sent into the mouth through the pipeline.Oxygen cylinder is a high -pressure container for storage and transportation of oxygen. Generally, the alloy structure is made of steel heat and suppression, and cylindrical.

2. What are the precautions for using Underwater pusher use

I have briefly understood the Underwater pusher and what cooperation is better. Then let's take a look at the precautions of the Underwater pusher!

1. Charging the battery, and it is only installed in the Underwater pusher before use.

2. Make sure that the ventilation holes are tight.

3. Put the propeller into the water, and the handle, the external rectification and the exhaust port will be filled with water.

4. When you are ready to start, please set the total switch to the position of "opening".

5. Press two at the same time and twist the propeller.(There will be a short reaction time before the propeller rotation)

6. The loose button can turn off the propeller.

7. Every time you take the product out of the water, the total switch is tone to the position of "Guan".

8. When using a pusher, in order to achieve the fastest speed, the correct posture is very important.

Note: In order to ensure that you can return safely, please do not snorkel to a place too deep.

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.

1. What are the classification of sneakers?

1. basketball shoes

Due to the vertical jump of basketball and the movement of left and right movements, basketball shoes are usually strong in large structures, outstanding cushioning performance, and enhance the athletes' endurance and elasticity.The water wave pattern of the sole can provide the friction of stopping, starting, and turning; the reversing system combined with the natural reversal of the front and rear feet, improves stability and control, and responds more sensitive and fast when it is rapidly turning.The sole uses human -shaped "miracle rubber", which will not leave a mark on the wooden floor of the basketball hall.The rear and flat, the large forefoot with deep bending grooves greatly enhances contact with the ground.basketball shoes are mostly synthetic or leather, making it stronger, and most of them are designed with medium and high -top -high -top design to protect the ankle.

2. tennis shoes

tennis is a movement that requires fast movement in both feet, and the probability of movement in the forefoot is particularly high. Therefore, the design of tennis shoes will focus on the fixed effects on both sides of the feet and the degree of wear resistance at the bottom of the front foot.Generally, the sole is relatively wide and flat, and has a sense of stability.The upper is used by the combination of leather or leather and nylon mesh, which can make the shoes more holding, shock absorption and buffer.The sole is also generally non -slip water ripples, which improves the speed and effectiveness of horizontal motion.

3. football shoes

There are rubber shoe nails on the soles, and the upper is made of kangaroos or synthetic Skin.Kangaroo Skin is like the second Skin of athletes, making it feel good for the ball, light and durable.Adidas also uses Predator Falcon technology to enhance the control, directionality and accuracy of contact with the ball. While the sole trap is to reduce the grip performance of the sneakers while reducing the nails to the ground pressure.

Second, different sneakers type selection

1. Classic (Classic)

This type of sneakers are particularly versatile. Whether you go to work or out of the street, you can control any dressing.A pair of black or white classic shoes can be blended with your costumes well, and can be worn all year round, and it will never be outdated because of the classics.

2. Comfortable

Classics may not be the most important. For those who wear sneakers all day, comfort is actually the most important choice.When it comes to comfort, everyone may think of Boost. As the most popular cushioning black technology design, everyone has always been considered as the most comfortable sneaker series in history.

3. wear -resistant (wearProof)

Wear -resistant sneakers are usually cheap, very durable and wear -resistant, and never worry about scratching or wear.No matter what kind of torture, this type of sneakers can bear it.You will still love them like when I open the box hundreds of times, because they are really resistant.

1. How heavy is a set of camping equipment

For Camping enthusiasts, the weight of camping equipment is a problem that needs to be considered carefully, especially friends without cars, camping equipment must be placed in the Camping Backpack, which will undoubtedly increase your burden.How heavy is the equipment?

Generally speaking, the number of camping equipment is different, and the weight is naturally different. Lightweight camping equipment includes the necessary basic equipment such as tents, Sleeping bags, moisture-proof pads, clothes and shoes.A 50-liter Camping Backpack can meet the demand; if there are more camping equipment to be carried, you need to use a larger Camping Backpack. Usually 50-60 liters Camping Backpack load of 10-20 kg, more than 60 liters of Camping Backpack load 20 weight 20-30 kg.

In terms of the weight selection of camping equipment, you mainly consider your own weight. Generally, if you want to carry more and heavier camping equipment, it is recommended to drive to the Camping site; if it is your own Backpack, it is advisable to be lightweight.

2. How to lightweight camping equipment

If you go out with a Camping Backpack, if the camping equipment is too heavy, it is undoubtedly finding a hardship for yourself, so you need to try to lightly improve the camping equipment as much as possible.

1. Small Backpack replace the big Backpack

The larger the space in the Camping Backpack, the more you want to carry more things with you. Having a smaller Backpack will force you to have a better choice for what you bring. This is a good start.If you only Camping for 1-2 days, the Backpack of 40-50 liters on the back is enough.

2. Use a small bottle to carry shampoos, sunscreen, toothpaste, etc.

You can't use a whole bottle of shampoo, sunscreen, toothpaste or hand -toilet in a Hiking, then don't bring a complete packaging. Various types of bottle are suitable for installation according to the amount.

3. Use the cricket stove instead of a full set of cooking systems

The basic components of the Outdoor gas stove are fuel tanks and burners. With a pocket stove, you only need to screw the burning head directly to your fuel tank, and then put the pot on it to cook, not only simple and light.

4. Use small aluminum pot instead of stainless steel pot

Stainless steel cooking utensils are strong, affordable and durable, but very heavy. Lightweight small aluminum pots can effectively reduce the weight of camping equipment, and it is easy to clean, but the durability is slightly worse.

5. Use the water filter

Water is one of the heaviest parts in the Backpack. If there is a water source in the Camping place, you can not carry water or only carry a small amount of water; if the Camping or Camping site is not provided, it is recommended to use water filters to reduce the amount of drinking water.A simple and efficient water filter, the weight is very light, which can reduce a lot of Backpack weight.

6. Plastic and resin water bottle instead of metal kettle

In the same volume, the weight of a soft and squeezing water bottle is even much lighter than the weight of a hard plastic kettle, let alone a metal kettle.And when you don't need it, they can roll up and occupy smaller space.

7. Small folding knife instead of multifunctional tools

The functions of multi -functional tools include screw knives, pliers, threading clamps, and awl. Although it is easy to use, it is much heavier than small folding tools such as Swiss Army knife. Maybe your Camping rarely uses some of the multi -functional tools.tools, therefore, folding knives like Swiss Army knife according to the actual situation and the environment are often enough to deal with.

8. Close foam cushion instead of inflatable sleeping cushion

The weight of the closed -hole foam pad is light, and it can also be easily folded into different shapes. You do nt have to worry about piercing or carrying a patch bag. When your Backpack is too heavy, you can consider replacing your inflatable sleeping pad to foam pads.

9. Put the pillow with a bag for spare clothes

The Camping will carry some spare clothes and stuff them into a small bag to be used as pillows, so that there is no need to bring an additional pillow.

In general, the so -called lightweight of camping equipment is to find a balance between Camping comfort and walking comfort. One important principle is to find a variety of uses of camping equipment you have carried, not to carry more specific onesEquipment designed for certain needs.

1. Which of the aluminum alloy and steel pipe of the Outdoor trolley is strong

Small Outdoor carts are a practical, convenient and multifunctional Tool, which provides great convenience for your Camping life.If you want to enjoy a comfortable and pleasant Camping life, then you must choose a high -quality Outdoor cart!So the question comes. Which of the aluminum alloy and steel pipes of the Outdoor trolley is strong?

The sturdy of the steel pipe of the Outdoor trolley is strong.

1. Steel is a collective name for the iron carbon alloy from 0.02%and 2.11%of the percentage of carbon content.The chemical composition of steel can change greatly, which contains a small amount of elements such as manganese, phosphorus, silicon, sulfur and other elements, and carbon -containing steels with less than 1.7%of the carbon steel.

2. Aluminum alloy is alloy with aluminum as a base, which is one of the light metal materials.The product characteristics add a certain amount of alloys with aluminum as the base, which is one of the light metal materials.

Second, which is the best Outdoor trailer aluminum alloy and steel pipe

Steel pipes and aluminum alloys have their own advantages. Which material choose depends on personal needs and scenes.

1. strength:The steel pipe has a strong structure and higher strength. It is suitable for heavy Outdoor trains, and aluminum alloy is more suitable for making light Outdoor trains.

2. maintenance cost:Aluminum alloy Outdoor trolleys need less maintenance because aluminum is not easy to rust or suffers from other damage.

3. Performance:The aluminum alloy body is lighter and has better acceleration performance and lower fuel consumption.

4. price:Under the same size and intensity, aluminum alloy body is usually more expensive than the steel pipe body.

Therefore, according to your needs and budgets, you can choose appropriate materials to choose Outdoor carts.
