Is the risk coefficient of parachuting high?

Relatively speaking, parachute is far from everyone's imagination.Especially the two -person parachuting that ordinary people can experience, the safety factor is relatively high.From the data alone, the rate of parachuting death was about one hundred thousand.And most of the accidents occur in single -person skydiving players holding photos.A double skydiving experience and safety coefficient depends on the professional level and equipment of the parachute base where you go.

From the perspective of big data around the world, parachute is a relatively high safety exercise. The safety factor is about the same as you go to the amusement park to play roller coasters!If it is not safe, it will not gradually evolve commercialization if it is not safe.The parachute contains a three -layer emergency protection mechanism. The first layer is the main umbrella, the second layer is a spare umbrella, and the third layer is an automatic umbrella.

Will there be a sense of weight jump?

In fact, during the entire skydiving process, there are two places a sense of centrifugation (weight loss) will be particularly strong:

1The process of rising planes

Most of the time when the plane rises (the aircraft rises (the aircraft rises (the aircraft is rising (the aircraft is rising (most of the time is stable (10-15Around minutes), it will always keep a certain amplitude flying up, but occasionally adjusts the angle according to height and wind direction.For example, the amplitude of the tilted upward becomes larger, turning left or right, etc. When the moment the change is changed, it will feel a centrifugal force.

The feeling of centrifugation is very short, just as the bus brakes is as short as possible, and the one comes quickly. You just feel the centrifugal power. The fear of the fear has not had time to surge.Leave3Second, the stimulant before jumping is beautiful.

2, Before jumping out of the cabin5Second:

This is better to understand that people change from a relatively static state to a state of a fast fall (200kilometer/ /Hour, that is, per second50Mi), "Acceleration" is still very strong, especially with psychological changes. The feeling of centrifugation is more strong.Your heart will be close to your back, you will involuntarily hold your breath, because you will feel better.

wait5After the second, you will completely get away from that feeling (relatively uniform speed), but at that time you will be a little nostalgic. The bloodline is sprayed. Don't be too cool!

5000How long does it take for the rice parachute to land?

5000Mi is the most common height of military skydiving and special forces. It is also the height that some very popular and extreme athletes like to try.From this high skydiving, the landing time is usually in6About minutes.However, the specific time still depends on factors such as airflow, weight, wind speed, and parachute area.During the parachuting process, the skydiver needs to adjust the landing speed and direction in a timely manner according to his own experience and weather conditions to land smoothly.

One, what is Fish drift

Fish drift is a Tool for the message reaction of the fish biting hook during fishing, also known as floating drift. People can not only judge the situation of fish eating through Fish drift, so as to determine the timing of the pole.The fish is biting the hook, so the Fish drift is an important part of the harvest of fishing.

Second, what is the Fish drifting?

Fishermen know the importance of Fish drift. It is called "the eyes of the fisherman". Generally, the role of Fish drift is mainly five points:

1. The information of the fish swallowing fish bait

The Fish drift response is very sensitive. When the fish touch and swallow the bait hook, the position of the bait hook will change. This change can be passed to the Fish drift through the fish line immediately.

2. Display the location of the bait

In the wide waters, the fish is clearly on the water, which can accurately display the location of the fishing point.

3. Make the bait hook in different water layers

By adjusting the weight between Fish drift and lead pendant, the bait hook can stay at different depth water layers to Fish Fish that lives in different water layers.

4. Show the depth of water

During the bottom fishing, the length of the Fish drifting to the bait hook is water depth.

5. Show the type of bite fish

Different fish feeding habits are different, and the actions that reflect the Fish drift are different. According to the different reactions of the fish, it can be roughly determined what the fish bite.For example: the sides of catfish, carp, catfish, etc. are flat and approximately ellipse. When the fish is close to the plane or horizontal state of the bottom of the river, because the bottom of the bottom is raised into an oval shape, the fish mouth and the bait of sinking to the bottom of the river cannot be swallowed.bait hook.Therefore, catfish, carp, catfish, etc. When looking for food at the bottom of the river, you must dive and swallow.When the fish tried to tentative bait hooks, due to the continuous closed tension of the fish mouth, the Fish drift showed a small motion of the swing.When the fish swallowed the bait hook, the fish body was restored to the horizontal state from the half -end state.

3. What do you think of the Fish drift of the fish during fishing

During fishing, the drifting phase of the fish is a movement shown in the floating drift during fishing. Due to the differences in fishing, fish love, water love, season, etc., the floating phase is also ever -changing. Commonly there are generally the following:

1. Drift

Drilling means that the floating float suddenly floats, exposing the body or lying directly on the water.This rafting often indicates that catfish bite hooks.There are also three types of rafting.When the first two kinds of drift news appeared, the fish hook was in the mouth of the fish. Generally, there was a fish with a rod. When the drift appeared, it might be that the fish's back of the fish poured up the float, or it may be halfway.

2. Black drift

Black drifting means that the float is completely sinking into the water. This kind of drift does not necessarily have fish.If it is first or then sinking, it is usually carp hooking; if the float sinks quickly, it is likely that the small fish is nest; if it is sinking and then rising, it often means that the fish has spit out the fish hook.If it appears first and then go, there is a high probability that there is a big fish hook.

3. Drift

Drifting is also called Diao.Everyone should pay attention to distinguishing the drifting of its and pendant fishing. Most of the drifts of pendant fishing are not fish.If you lift it first and then lift it, most of the catfish bite the hook; if you order it first, it is likely that the carp is biting the hook; if the broken point continues, it is usually a hungry big fish to eat bait.

4, drift

There is a division of fast walking and slow walking. Usually, it is about to show that there is a fish Fighting for food, and slow walking is often bite with big fish.The emergence of drifting is usually related to grass, carp, green and other.If you jump while walking while walking, it is usually a big green fish bite the hook; if you walk while walking, it is mostly a small fish grabbing bait; if it is hopping, most of the fish already bite, and immediately lift the pole.

5. Shake

Shaking drift is also called swinging, which is specifically manifested as the left and right swing of the drifting tip.If you walk while walking and even lift, it means that the hook bait has been entered.If you do nt rise or fall, do nt order or go, mostly pass by the big fish; if you shake the side and rise, you will fall, and then keep it.

6. Flying

Flying drifting refers to drifting very fast.If the fishing is flying, it means that there is a fish to fight for food, and the fish will leave.

1. How to clean the climbing suit

Mountaineering clothes are made of clothes made of special fabrics. They are mainly worn during mountaineering. If the climbing clothes are soiled, it may block the waterproof and breathable film and accelerate the aging of the mountaineering clothing. Therefore, it is necessary to clean it regularly.The cleaning method of mountaineering clothing can be divided into two types: machine washing and hand washing:

1. Machine washing method

Soak the climbing mountaineering for five minutes before the machine washing, then take the appropriate neutral detergent. Use a soft brush to focus on the dirty places. Rinse it, put it in the washing machine and a small amount of neutral detergent, adjust the washing machine to the chemical fiber mode washing the chemical fiber mode to washAfter washing, do not dehydrate with a dried machine, just remove it and hang it in the ventilated place to dry.

2. Hand washing method

First use warm water below 40 C, soak the climbing suit, and then directly dip the appropriate amount of washing agent with a sponge or cotton cloth to wipe the surface layer of the mountaineering suit, simply rub it, and use a brush to the stains.String some to dry in the ventilation place.

Generally speaking, if it is not particularly dirty, you don't need to clean the whole mountaineering suit and clean the staining parts.

2. What should be paid attention to when cleaning the climbing suit

Mountaineering clothes are not like cleaning like ordinary sportswear. Pay attention to methods and skills when cleaning. So how to wash mountaineering clothes?The precautions for cleaning the climbing suit are:

1. Washing method

Do not wash it with water directly when cleaning. The front part and the waterproof cloth can be used to stick some water with waste toothbrushes or dry towels to clean. Pay attention to the brushing too hard, especially the inner part.

2. Wash the fleece part alone

Do not wash the fleece part of the mountaineering clothing with the climbing suit. It should be removed with soap or laundry powder to avoid directly cleaning and leaving unsightly stains.

3. cleaning skills in the lining part

The inner lining part of the climbing clothing should be carefully cleaned. You can touch some soap or washing powder to gently wash it. You must clean the dirt. You can wash it a few more times in a dirty place.

4. How to dry the climbing suit

It is more troublesome to dry after cleaning the mountaineering clothing, because the washing machine can not be dehydrated, and it is difficult to screw dry it if you twist it. Generally, you can use a hanger or other things to support the mountaineering clothing after cleaning.Let the sun be dried to dry. Be careful not to blow it with a hair dryer or sun. Although it can be dried faster, the damage of the fabric material is relatively large.

The role of sports shoulder guard

Sporty shouldersThe main role is to support and protect the shoulders and reduce the damage or disease caused by the shoulder.At the same time, sports shoulders can also play a role in preventing cold and warmth.

However, the most important thing for sports shoulder guards is not to use during exercise, but later protection and protection after our shoulder injury.We are most often divided into three Levels of sports shoulders: the first -level shoulder -shoulder shoulder guards are mainly developed and developed for some sprains of shoulder sprains.The second -level protective shoulder guards are mainly targeted at diseases such as ligament loose and pain.Three -level protection is generally equipped with strong support items such as aluminum strips, which are mainly worn for shoulder injuries.

Movement dislocation and prevention

1.

The elbow joint is dislocated, and it should be kept quiet, do not move, and do not rub the injured parts.First of all, in order to avoid injuries again, you should sit down or lie down to check whether there are other wounds to keep warm and prevent shock. Usually the sitting position is most comfortable.The fixed dislocation site is the best way to reduce pain.

2. Want and ask

The wounded was sitting, and the assistant held his upper arm as a confrontation traction.The therapist holds the wrist of the wounder with one hand, continuously traction towards the original deformity direction.Joint reset.However, if rescuers are not very familiar with bones and cannot judge whether the joint dislocation is combined with fractures, do not easily implement the reset of elbow joint dislocation.

3. Do you need to go to the emergency department

When the elbow is dislocated, it should be taken to the Hospital immediately.At the same time, you can bend the elbow into right corners, hold the forearm and elbow with a triangle scarf, and hang it on the neck.If there is no rescue before, the wounded is judging by the joints according to the injury of the elbow joint. Do not force the injured limb straight at the semi -extended position to avoid causing greater damage.You can use a normal arm to unbutton the buckle, use the placket to hold the injured forearm from the bottom up, tied to the neckline, so that the injured elbow joint is fixed on the chest, and then went to the Hospital for treatment.

4. Team doctor suggestion

After dislocative joints, it takes a certain period of time to recover after reset. During this time, try not to be frequent or moved by the injury to the earth's activity.Inappropriately premature and frequent joint activities will cause obstacles to the joint capsule and ligament repair process, cause the joint capsule to relax, and become the habitual dislocation of the joint, which is even more troublesome.

Method of preventing dislocation

For exercise damage, prevention is more important than treatment. The following editors provide several methods to prevent dislocation:

1. Be careful before the activity to prepare activities, such as doing some surround and stretching activities so that all joint parts can be sufficient activities.

2. Before the activity, check whether the sports equipment is firm and whether the venue is flat.

3. Protection should be taken during activity, especially to strengthen the protection of injured parts.

4. Do your best, do some sports activities that are suitable for your physical strength, and never do dangerous movements that cannot be done.

5. To avoid the direct collision of violence as much as possible, do not jump directly on the hard land (cement field).

sports The manufacturing of protective gear is mostly chemical products of different materials such as nylon, rubber, polyester fiber, etc., which have the advantages of stretching, toughness, comfortable touch, good breathability, etc., and combined with elastic metal strips as support and auxiliary magic buckles as support and auxiliary magic bucklesPressure and fixing, improve the stability of joints and muscles, keep it in a suitable stress range, and protect the joints and muscles during the movement of the movement.

How to choose a sports gear?

A good sports protective gear must have the following characteristics:

Warm and breathable:These two seemingly conflict characteristics are revealing the importance of dialectics. You have me and you have you.The warmth is to keep the body's calories in non -exercise state without being easily lost, so that the parts that need to be protected are not easy to be injured and can better recover.At the same time, it is necessary to ensure breathability, because exercise must sweat, good breathability, allows sweat to quickly discharge, so that the wrapped parts can be dry and comfortable.

A good protective gear is like the second layer of Skin of the human body. It not only has a good sweaty effect, but also maintains the water of the body's surface at the same time.It allows you to have a very good state in exercise, and it can be more comfortable in recovery.

Compression and support:Good protective gear has a very professional design, which is in line with the curved arc design of the protection site, three -dimensional tailoring, with the scalability and magic stickers of the protective gear.It also ensures that the wearable part has very good flexibility.Add the elastic metal springs to some special protection gear that require special protection, strengthen support, and help the protection site in the process of frequent exercise to maintain the stability and impact absorption function of the joints.The possibility of slowing down due to improper stress or overer fatigue.

The overall comfortable covering and good support performance, providing the part that was once injured to get better protection, and effectively avoid the occurrence of second -degree damage.

Protection and recovery:This is also the most important purpose of protective gear. The pressure transformation of the protective gear to pressure muscles can reduce pain, promote metabolism, enhance exercise function, enhance the stability of joints, and have a good correction effect on the injured parts to prevent injuries again.The soft fabric uses a unique weaving method, which has unique ductility and excellent air permeability, which can produce medical effects, comfortable to wear, accelerate swelling and congestion absorption, improve exercise function, and can quickly excrete moisture. ThisIt is very important for recovery.
