1. What are the differences between Paddle board and surfing board

For those who are full of enthusiasm for the ocean, as long as the surfing board or standing Paddle board stands on the places closest to the beauty of the ocean, the surfing board and Paddle board are water sports, so what is the difference between them?

1. Different force

Sup Paddle boards and surfing boards can surf, but the most obvious difference between the two is to stand by the Paddle board or SUP to move the paddle.Shoot to ride waves or turn.

2. Different appearance

The size of the standing Paddle board and the surfboard is very different.The SUP board is much greater, and it is generally more than 6 or more at home in China. It is usually heavier and thicker.The size of the surfing plate is usually ranging from 5 to 9 feet and lighter.The reason for the difference is the use of Surfboards.When the SUP board slides at sea, it is usually stable in order to better maintain the water.The surfing board means ride with waves or along the waves, which requires greater mobility and flexibility.

3. Different volume

Standing Paddle boards usually have a larger volume than Surfboards.The larger volume usually means thicker (sometimes), longer (almost always) and wider (almost always). The advantage of having a larger volume is that it can be easier to catch waves.

4. Different mobility

SUP Paddle board surfers and surfers can ride the same waves, but generally because the SUP Paddle board is larger than the surfboard, the response and mobility will be poor.

5. Different conditions for development

The surfing movement must be carried out without waves.And even if the paddle surfing is completely without waves, it can be accelerated with the help of paddles to take into account long distances and surfing.In the inland rivers and lakes, and even the indoor swimming pool can be carried out.Under normal circumstances, surfing boards are mainly surfing at sea, and Paddle boards are mainly played in quiet water lakes.

6. Different gameplay

The surfing plate is mainly surfing. In addition to surfing, Paddle boards also derived that Paddle board yoga, paddle campaign, Paddle board racing, and paddle fishing.

Second, which is difficult for Paddle boards and surfing boards

The difficulty of surfing board is generally greater than the Paddle board.

Generally speaking, the Paddle board is more generous than the surfboard, so it is easier to master the balance, and there is a paddle in the hands of the operator.Difficult surfing technology, so even rookie players can get started immediately.

The surfing movement is usually more particular about the professionalism of the player, and it must be performed without waves, so the difficulty and the entry threshold are higher than the Paddle board.

Third, can the Paddle board be used as a surfboard?

Can.

The Paddle board itself can also surfes. Compared with ordinary surfing plates, the Paddle board is longer and wider, relatively heavy, and can be better stable in the water.However, the mobility and flexibility of the Paddle board will be worse than the surfboard. The surfing needs to ride waves or turn according to the shift of the center of gravity. Therefore, professional surfing is better.

1. What are the types of Diving equipment?

Diving equipment can be divided into two categories: lightwear and heavy equipment, including some other accessories.

1. Light equipment

Lightweight equipment mainly includes diving mirrors, respiratory Tube and feet. These are basic equipment during snorkeling, also known as "diving three treasures".The diving mirror is made of pressure -resistant tempered glass, which has the function of balanced ear pressure and preventing water from entering the nasal cavity.The respiratory Tube allows divers to breathe during the water surface or swimming, saving the air in the gas cylinder.The feet provide the driving force for underwater progress.

Light -fitting is suitable for surface or shallow water diving activities, which is simple to operate, which is convenient for beginners and amateur enthusiasts.Its design focuses on comfort, ease of use and durability.

2. Heavy equipment

The reinstallation includes the respiratory regulator, the buoyantic adjustment (BCD/BCJ), the diving instrument, the gas cylinder, etc.The respiratory regulator regulates high -pressure gas to be a suitable pressure for divers to breathe.The buoyantic adjustator helps the divers maintain a neutral buoyancy underwater to facilitate movement and operation.Diving instruments integrate a variety of functions, such as depth, northern needle, and residual pressureometer to provide comprehensive underwater data.The gas cylinder stores high -pressure air or mixed gases for divers to breathe.

Heavy equipment is suitable for deep water and professional diving activities. It has high technical content and provides a variety of safety and convenient functions.Its design focuses on high performance, high reliability and high security.

3. Other accessories

Other accessories include diving masks, diving knives, diving flashlights, diving gloves, diving boots, etc.The diving mask provides comprehensive protection, suitable for various diving environments.The diving knife is used to relieve underwater disorders.Dive flashlights and diving gloves to protect the hands and eyes of divers.Diving boots protect the feet of divers and prevent injuries.

Other attachments provide additional protection and functions according to specific needs.Its design focuses on versatility, protection and convenience.

Second, different Levels of divers to buy Diving equipment list

1. Junior diver: jellyfish and sunscreen

First of all, jellyfish clothes are necessary.It can not only protect your Skin, but also make you more comfortable underwater.sunscreen is also essential, especially for junior divers who don't have much sunscreen experience.Remember to apply sunscreen 30 minutes before the water, so as to better protect the Skin.

2. Intermediate divers: bite, head, gloves, Ding Ding stick

In the intermediate stage, there are more equipment choices.Bite your mouth and hood is a good helper for underwater communication, especially when you need to communicate with underwater partners.gloves and Ding Ding rods are to prevent accidental damage, such as encountering corals or marine life.These equipment can not only protect your body, but also increase the fun of diving.

3. Senior diver: face mirror, foot, wet clothes, computer tables, flashlights

At the advanced stage, the choice of face mirrors and feet is even more important.Noodle mirror is your "eye" underwater, and it is very important to choose one that suits you.The foot of the foot directly affects your swimming efficiency, and a pair of good footsteps can make you more freely underwater.Wet clothes are also essential, especially for those who like to dive for a long time.The computer meter and flashlight are to meet the needs of night diving and complex diving.

4. Rescue diver: BCD and breathing regulator

At the stage of rescue divers, the choice of equipment is more professional.BCD (buoyancy regulator) and breathing regulator are the core of water and lung equipment. With your own regulator, you can make you more at ease during diving.

5. Diving coach: first aid package and facial mirror

As a coach, emergency packages are necessary. This is to cope with emergencies and ensure the safety of themselves and students.In addition, coaches need to prepare multiple facial mirrors and computer tables to meet the needs of students.

3. A must -have equipment for free diving

Freedom diving three -piece set: facial mirror, respiratory Tube, foot.

1. Facial mirror:It is divided into two types according to the volume volume. The volume suitable for free diving is small, and the shell of the facial mirrors suitable for water and lung diving is harder. Plastic lens facial mirrors are easily scratched by submarine impurities.

2. Respiratory Tube:It is used to provide oxygen during diving, length and comfort are the key to choice.

3. Foot:Materials are divided into three types: plastic, glass fiber and carbon fiber. Beginners can choose plastic or glass fiber material, and carbon fiber material is suitable for senior players.

4. Other equipment

(1) Nasal clamping: help clamp the nose to facilitate qi.

(2) GOPRO: A must -have Tool for underwater dynamic photography.

(3) Wet clothes: warm in water, it is recommended to choose 3mm thickness.

(4) Foot box: easy to carry, suitable for different potential points.

The correct way to wear the bloated life jacket

1. Put your head into the life jacket.

2. Tie the straps on the left and right sides.

3. Pull the tension on the left and right sides, the inflatable valve is opened, and the life jacket is inflated within a few seconds.

The inflation function of the qi -blee -type life jacket

1. Manual inflatable: Pull the pull rope on the inflatable device before or after falling or after falling or after falling or after the water, so that the tie rod is not less than 90 degrees, the thorns are pierced to pierce the gas cylinder film, the high -pressure CO2 gas is poured into the airbag, and the buoyant is generated after the gas swells.

2. Automatic inflation: After the water is dropped into the water, the life jacket is immersed in the water to soften the water sensitive element in the automatic device, loses blocking the needle, and the spring stretch pushes the piercing needle to pierce the gas cylinder sealing film CO2 gas to fill the airbag and generate buoyancy.

3. Blowing the mouth is a one -way valve type, and the one -way valve is automatically closed after blowing.

What are the types of qi -style life jackets?

Blay -type life jackets are divided into three types according to the appearance style:

1. Vest -style qi qi and life jackets are commonly known as horses -type qi qi life jackets.

2. scarf -style qi and life jackets are tied to the neck like a scarf.

3. Belt Bloating life jacket, also known as qi -type Belt life ring, water seat Belt.

There are two specifications of all styles of qi and life jackets, one manual type and one automatic type.Suitable for fire, maritime police, water police, armed police, border defense, maritime affairs, fishery administration and other units to engage in water rescue activities.

The performance indicators of qi -blee -type life jackets

1. Automatically inflatable within 5 seconds of water, generate more than 15 kg of buoyancy.The 24 -hour buoyancy loss is less than 5%, and the performance of the main accessories and materials meets national standards.

2. The airbags are made of imported polyether TPU materials, which have excellent aging resistance and hydrolysis characteristics.

3. The dry side of the water is greater than 120mm, and the backward angle is 20-50 degrees.

4. The product is standard for search whistle and reflective stickers.

What are the fabrics of qi -qi -type life -saving clothing

Bid-type life jackets use TPU fabrics, TPUs (Thermoplastic Polyurethanes), and thermal plastic polymethlate, which is a linear embedded cluster composed of low polymer polymirol soft segments and diisocyanate-expansion hard segments.The TPU can be made of saliva, film blowing, pressure delay, or coating, which has the excellent characteristics of good elasticity, strong toughness, abrasion resistance, good cold resistance, and environmental protection and non -toxic.TPU fabric has the following characteristics:

1. Hardness planning wide

After changing the ratio of the components of the TPU composite fabric, the Tent cloth can get products of different hardness, and follow the hardness of the hardness. Its product still adheres to excellent elasticity and abrasion resistance.

2. High mechanical strength

The carrying capacity, impact resistance and shock absorption function of TPU composite fabric products are excellent.

3. Extremely cold -resistant

The glass state changing temperature of the TPU composite fabric is relatively low, and the canvas factory still adheres to excellent elasticity, softness and other physical functions at minus 35 degrees.

4. Good processing function

TPU composite fabrics can be processed with common thermoplastic materials, such as injection molding, extrusion, pressure extension, and so on.At the same time, the TPU composite fabric/cloth processing with certain polymer materials can obtain a polymer alloy with complementary functions.

5, oil resistance, water resistance, mold resistance.

6. Good recycled utilization.

There are two methods of TPU composite fabric. One is called and then sticked: first make it into a TPU film, then fit the glue with the fabric, and the other is called online composite: apply the glue on the fabric may not be glued.The fabric is made into a TPU composite fabric or clipped mesh.

The difference between organic matter and inorganic objects

1. Different definitions

Organic objects are carbon -containing compounds (carbon dioxide, carbon dioxide, carbonate, carbonate, carbonate, bicarbonate, metal carbides, cyanideExcept for oxides such as chemicals, thiocyanides) or general names of hydrocarbons and derivatives.

Inorganic compounds usually refer to compounds without carbon elements, but a few compounds containing carbon -containing elements, such as carbon dioxide, carbonate, carbon monoxide, carbonate, etc., are not organized, so such substances are also inorganic.

2. Elements are different

There are few elements of organic matter, such as C, H, 0, N, P, S, X (halogen: F, (CL, BR, I), etc.

Inorganic objects are mainly water and some inorganic ions, such as sodium ions, potassium ions, calcium ions, magnesium ions, chloride ions, sulfate ions, etc.

3. Different properties

Except for a few organic compounds, they can usually burn.Compared with inorganic objects, their thermal stability is poor, and the electrolyte is easy to decompose.The melting point of organic matter is low, generally does not exceed 400 C.Most organic matter is insoluble in water.The reaction between organic matter is slow, and methods such as catalysts often need to be added.Moreover, the reaction of organic matter is more complicated, and the inorganic objects are mostly easy to dissolve in water. The chemical reactions are simple, difficult to melt, and heat resistance.

4. Different types

There are many types of organic compounds and huge numbers (more than 30 million species are known, and they are still increasing at a rate of millions per year).

How to judge organic matter and inorganic objects

1. Chemical composition

Organic substances usually contain carbon (C) elements, and combine compounds with elements such as hydrogen (H), oxygen (O), nitrogen (n), sulfur (S), and phosphorus (P).Carbon is connected into a chain, ring or complex three -dimensional structure in organic matter in organic matter.

Inorgana may not contain carbon or carbon, but its properties and structures are closer to the inorganic system, such as carbonate, carbon monoxide, carbon dioxide, etc. These are inorganic compounds.

2. Molecular structure and composition

The molecular structure of organic matter is generally more complicated, with a large molecular weight, and carbon atoms often constitute the osteogy structure.

The molecular structure of inorganic objects is relatively simple, and the molecular weight can be large or small. In most cases, the carbon does not serve as a skeleton component.

5. Physical properties

Organic substances often have low melting points and boiling points, easy to volatilize, difficulty in soluble in water and easily soluble in organic solvents.

The melting point and boiling point of inorganic objects are high, and they are not easy to volatilize. They are usually easily soluble in water or exist in water in the form of ion.

6. Reactive and biological activity

Organic substances usually have more complex chemical response, and the response speed is relatively slow. A variety of types of reactions such as replacement, bonus, elimination, etc., and many organic matter has biological activity and can be absorbed by the organism.

The reactivity of inorganic objects is relatively stable and the response speed is fast. It mainly manifested as acid -base reactions, oxidation reactions, etc. Most inorganic objects do not have biological activity.The vast majority of inorganic objects in nature can be included in the four categories: oxide, acid, alkali and salt.

What are the organic mattertype

1As well asAccording to the type of chemical bond: organic matter can be divided into co -price bond organic matter and non -covalent keys.

2,It is composed of elements: organic matter can be divided into carbon organic matter, nitrogen organic matter, phosphorus organic matter, sulfur organic matter, oxygen organic matter, chlorine organic matter, etc.Essence

3,According to the molecular structure: organic matter can be divided into alkane, olefin, aromatic compounds, aldehydes and ketones, amide, alcohols, esters, acids, carboxylic acids, nitrate, sulfonate, etc.Essence

4,According to activity: organic matter can be divided into active organic matter and non -active organic matter.

5.According to molecular weight: organic matter can be divided into polymer organic matter and low molecular organic matter.

1. Basic sprint training training

1, Spinal strength (analyzing the functional disorders of the body)

2, Model mode training: physical posture, legs and knee -knee stretching movements (hip opening), arm movement (the shoulder joints must be flexible, the more the arm swinging amplitude, and the larger the amplitude of the lower limb movement)

3, Training in large core areas (the principles of pelvis, thorax, hip joints and the entire spine, cylinder principle)

4, Power Training (General PowerSpecial force)

2. Training method training method

1, Frog jump: Be careful to jump continuously without staying in the middle.Try to jump as far as possible, but don't rush to achieve success. Generally30arrive50About rice, enhance the practice of thighs and basic forces.

2, Jumping steps or stairs: You can jump with one foot, feet, and jump continuously. It is best to wear a leg protection when jumping. Be careful to scratch your calf (enhance the explosiveness of the thighs and the speed of the calf).

3Steak: The spare time can use this simple movement to enhance the toughness and strength of the ankle joint.

4, Live high -lifting and high legs: Find a barbell or other load -bearing things (you can buy a secondary sandbag to tie your legs, the weight is suitable for you), quickly high -lifting, increase the comprehensive ability of the thighs.

5, run back: Find the wall or double bar, hold your hands, your body and the ground become45--60At the angle, quickly exchange your legs. Pay attention to the support of the legs and move your legs as much as possible.

6Running: run with leg tied sandbags.Garway Running: one time Running600rice or800rice.The straight road is at full speed, jogging or walking.

3. How to carry out sprint training plans

1When Running at the beginning, it is not easy to train too much. It takes a step -by -step, the strength is restored, and the muscle adaptation training stage takes about a week.

2Before exercise, you must take jogging warm -up to prevent exercise from injury.Cross -legged steps should be quickly and improve the muscle strength of the calves (this is the key to Running fast). It is done in five groups daily.

3, Highly lift your legs and send cross -exercise exercises. The steps must be large, increase the amplitude of the swing, the Running posture must be standard, and the spring rope is pulled forward to improve the waist and abdomen power.

4After 20 meters of frog jet, accelerate the Running, increase muscle explosive power, chase between athletes, and improve training fun.I believe that these methods will adhere to one month, and your grades will make progress rapidly.

Fourth, sprint training skills

1, Starting stage

The focus of the human body should be higher and at the front of the support point, which is conducive to acceleration.

The characteristics and structure of the action are as follows

FootThe foot distance (the distance from the back of the toe to the front foot is personalized)

Ankle jointEx to the greatest extent, appointment45Spend

Knee angle90120Spend

Hip heightPest by person

Starting movement: The power of the lower limbs and the upper limbs is sufficient, and the shoulder joint muscles are developed.When the Running is accelerated, the back of the back is straight, the arm and the shoulder joint are very flexible, the angle between the legs is very large, the hip joint is fully opened, and the ankle joint is fully stretched.

2, Accelerate stage

Accelerate goals: Maintain a balanced body posture to consume less energy and achieve maximum speed as soon as possible.

Accelerated Running action characteristics:

Physical posture (leaning forward45-55Spend)

Placing legs (hip and formation90Degree, the knee joint is smaller than90Degree, tight ankle joint)

Arms movement (elbow joint90110Spend)

Participate muscles: hip and knee joints participating in exercise (quadriceps and gluteal muscles), ankle joint and toe strength (gastrocity muscle and anterior tibia)

Explosive starting training is required to produce strength through the common effects of the hip, knee, and ankle, because the rapid starting technical requires the hip and knee tissue to have great elasticity.Good hip power helps athletes to separate their legs when the knee is raised. When contacting the ground, the elastic power reduces the power of the knee and hips, while reducing the time for contact with the ground.Starting ability training can help athletes provide the maximum acceleration ability.Starting training includes starting exercises in various poses, short -distance acceleration exercises, and sprint assistance technology exercises.

3, Transitional stage

The transition to the upright body posture and maintaining the speed of the acceleration stage, the transitional stage still needs to increase the power of the ground. The speed has been accumulating.2040The speed of the rice interval has been increasing.

Objectives to be achieved: By improving the movement economy of Running, reducing the rotation movement of the body during the Running process (the feet kick back and outside the outside, swing back and outer sides of the abdomen), maximize the rapid Telescope of muscle and nerves.The reaction ability makes the body reach the maximum speed.

4The absolute speed stage

The body leaning forward is not to run faster, but to maintain speed.The acceleration stage emphasizes the kicking action, and the maximum speed stage emphasizes"Cutting on the ground" action

Physical posture: Keep your body upright posture (shoulder to your hip, your hip to ankle is out of the ankle)

5. precautions for sprint training

1Do a good job of preparing activities before exercise.Track and field movement can easily cause muscle, joints, and ligament damage, especially the chance of injury to the lower limbs.The only way to prevent is preparation activities before the game.The more fully the preparation activities, the less easily injured.On the basis of jogging, the shoulder joint, elbow joint, back waist muscles, legs, knee, ankle joints and other parts are activated to strengthen the strength of muscle and ligaments, improve the sensitivity and coordination of the body, and prevent injuries.Essence

2, Before exercise or game, students should pay attention to maintaining good sleep and physical savings. Before the game, they should control too much diet and drinking water, let alone drink.

3After exercise or competition, you should do a good job of relaxing activities to restore physical and muscle strength as soon as possible.The method is to relax and beat each part of the body, massage each other, and massage each other.

4When the whole body is hot, take off the coat. After Running, you should put on the coat immediately to prevent the wind from the wind.The shoes and socks worn during long -distance Running should be soft and feet.

6. Relax after sprint 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.
