1. What does the tone of Luya Fish rod mean

The Luya pole is often marked with the tone as the hand pole.The tone of Luya pole, said in the English word "ACTION", the bending point of the fish stress pole body in the fishing rod is getting closer and closer to the front.The commonly used words "Slow" said that using the centrality as the boundary line of fast and slow tone. Generally, the fast -moving fishing rod is conducive to the operation of road bait and precise throwing.The pressure is smaller.

2. How to choose Luya pole tone

The tunability of Luya Fishing rods mainly includes SS tuning (ultra -slow tone), S tone (slow tone), MR adjustment (medium slow tone), R tone (medium), medium speed (MF), F adjustment (fast fast)), FF adjustment (fast adjustment), XF tone (super fast adjustment), etc.

The super fast pole, the pole is slightly bent at the closest to the pole, and the slow pole is closest to the handle.

The faster the tone, the more clean the fish pole.However, the catfish process is easier to decide and run fish, and the sticky fish has poor ability.

The slower the tone, the stabbing fish will be more procrastinating, but the fish will be more sticky during the catfish process, it is not easy to run the fish, and the pressure on the fish wire is smaller.

Make fish in the middle and upper layers of fish, such as raising your mouth, try to choose a pole within the middle, the bottom of the fish, and try to choose a fast -tone pole.

If you play with Texas, Hanging, and leading soft bait fishing groups, you must choose a fast -tone pole.If you play some hard bait, you can choose a pole with a slow tone.

When flowing or obstacles, try to choose a fast -tone pole, such as thunderbolt, you can quickly pull the fish away from the fishing point.

Basic swimming Training

1. Water training

First do watering exercises. In the shallow water area, bend over and immerse your head into the water, count silently, and see how long you can hold on.After repeated practice for a period of time, you will no longer be afraid of soaking your head, and the time of holding your breath will gradually extend.You can also do simple walking activities in the shallow water area to slowly adapt to water activities.

2. Drift

One role of learning is to practice balance.Human head is very heavy. As soon as the head is water, the load of the body is even greater. In addition, if you raise your head, your body will naturally sink.

In the shallow water area, stand back against the wall of the pond, bend over, extend your arms forward, buried your head into the water, and then lift a leg to the back of the pool wall, so that the body is flattened forward.Be sure to bury your head into the water so that your body can be flattened.

Try to relax as much as possible, don't be nervous, and gradually realize that water can float your body.After losing speed, the legs will gradually sink, and then slowly stand up.This gradually overcome tension and cultivate hydrophilicity.

3. Pour water in the arm and legs of the legs

After repeated practice several times, I have confidence and feelings about drifting.After the floating sense and balance are established, you can increase the advancement of breaststroke -arms water and legs.For beginners, these actions are very simple, and you don't need to focus too much on this.After you can swim, the quality of movement gradually improves.

swimming power training method

1. Basic strength

Basic power is the power basis we need to maintain the basic swimming technology. Everything behind the power basis cannot be talked about. There are many basic power training methods. There are many aspects.Or increase the strength with elastic rope.You can also enhance the strength of the lower limbs through Running, frog jump, and other strengths.The upper limb training can be treated up by the bodies, dumbbells, and so on.

2. Special force training

Special force training is mainly for some specific actions during swimming to exercise your muscle strength, carry -weight leg practice, straight -arm rowing exercises, and Russian turntable exercises.The explosive power is the combination of speed and strength when swimming. It is indispensable. Therefore, the training methods I recommend here are as follows. Put the jump, set up a long jump, and throw the ball on the back of the wall.

3. Pirellium training

Endurance training can be intermittent training with the intensity of the game to improve the ability of the body to adapt to the metabolism and the ability to provide energy to improve physical endurance.It is more obvious than the second, so the second training method is more selected.

swimming training technique

Warm -up skills before swimming

1. Press the legs on the front

This action will greatly help our knees. We generally need to do at least 20 groups of action.

2. Break -up action

This action is to better warm up our waist. Generally, we need to do 10 like this action.

3. Pulling heel

This can stretch our leg ligament muscles. This is also very important, because if the ligament does not warm up, we will not be able to eat it after we get into the water.

4. Warm upper limbs

We need two hands to stretch at the back. This is also the key. When stretching backwards, we need to pay attention to breathing. Generally, we need to do more than 10 groups.

5. Side presses

Minding legs is also very important. When measuring the legs, we need to pay attention not to press too hard. Generally, a group requires more than 10.

6. Warm upwards

First, the left leg or right leg, and then the other group, push in order, generally need to do 20 groups, and then we can swim in water.

1. Multi -deep breathing before formal holding the breath. Each time people breathe, they did not exhale all the air in the lungs in the last time. The oxygen in this part of the air has been used, which is not fresh.He took a deep breath many times before you stuck, completely excluded this part of the gas in vitro, and the inhaled gas that was inhaled again when he was deeply inhaled was completely fresh air.In addition, you can fully expand your lungs in many deep breathing, so that you can inhale more air than usual.

2. After inhaling all the air into the lungs and start to hold your breath, exhale from the lungs from the lungs and leave some gas in the oral cavity.repeatedly.This is to maximize the utilization of oxygen in the air for alveoli to fully contact the air inhaled in the lungs.

3. After the start of the breath, keep the body as quiet as possible. Do not have extra movements, because any movement needs to consume the energy of the human body, which will increase the oxygen demand.

4. By the last stage of holding your breath, when you feel that you reach the limit, don't exhale all the gas of the lungs at once. You can control your slow exhalation as much as possible. This process can let you hold your breath for 10 seconds.

Inflatable skills in water

1. Keep your breath in the water

Squat the side of the hand, the companion, or the coach's hand, so that the head did not enter the water to practice the breath, and stood up after several times, so that it did not need to protect the practice by themselves.The longer the breath time, the better.If the head feels uncomfortable, the exercise should be terminated to avoid damage.

2, exhale in the water

Squat the wall or companion's hand, put your head into the water, and then vomit with your mouth (nose) slowly. It is best to exhale with your nose alone.Stand up slowly after a period of time.The older the breath time is, the better.

3. Rhythm breathing

There are regular, rhythmic breathing, which is basically similar to the water in the water in front: exhale with mouth (nose) in the water. In addition to paying attention to the rhythm, you can cooperate with the movement of both hands.

Breathing practice method

Stand in the water, support the shore/pool wall with both hands, take a deep breath with your mouth, then squat to immerse your head into the water, hold your breath slightly, slowly exhale out with your mouth and nose, and gradually stand up and raise your head.When the water surface, quickly exhale the remaining gas.Then use your mouth to inhale quickly and deeply on the water, repeat multiple times to achieve proficiency.

The number of practitioners in each group should gradually increase, from more than a dozen to dozens of times. The group can stop slightly between the group and the group. After the breathing is basically uniform, do the second group of exercises.Every time you get out of the water, do not turn the water on your face. After all, you can't wipe your face every time when you swim.

Stepping on water

1. "Dog Plane" stepping on water

"Dog planing" means keeping your arms swinging in front of you, and at the same time, your legs are stepping on the water under the water underwater.

Advantages: You can do it without too many "formal skills".

Disadvantages: Very energy -consuming, which means that you can't use this method for a long time in water.

2. "shallow water" method

The so -called "shallow water" means that when you kick back and forth, your arms are expanded to maintain balance.When stepping on the water in this way, pay attention to keep your toes down. At the same time, one leg is kicked forward and the other legs should be kicked backwards, so as to form continuous front and back swinging.

Advantages: arms are liberated, allowing you to do other things when stepping on the water;

Disadvantages: Because you use your legs to float yourself on the water, it will make people very laborious.

3. "Frog" kick

When you kick your legs, you must keep your thighs, lift your feet to both sides, and then put them down.This method is also known as "narrow -thorium".At the beginning, the legs are vertically closer, then the calves are extinguished to the sides of the body, and the starting movements are quickly recovered, which is the "frog" action essential.

Advantages: Compared with "Dog planing" and "shallow water", "frog" does not need to be so tired;

Disadvantages: This method of kicking will allow you to float up and down in the water and cannot float on the surface relatively static.

4.

As the name implies, "paddling" is to move your arms as a paddle.When doing this action, open your arms completely, place them on both sides of the body, and immerse them under the water at the same time.The palm of the hand is inward, and at the same time, the palm is gathered in front of the body. When the palm is about to touch, quickly turn the palm of the palm out, and at the same time move your arms outward to the starting position.Try to finish a round with both hands.

Advantages: free your legs, so that you can combine the paddling movements of other feet at the same time, such as the "shallow water" method.

Disadvantages: You must immerse all parts except your head to the surface.

5. "Return" method

This method is also known as the "eggbeater" method. It requires you to draw circles in one foot in the water when you are in the water, and the other foot is drawn in the direction of the counterclockwise direction.This method is difficult to master, but it can greatly save energy.

Advantages: If you can fully master this method, you can save a lot of physical strength.

Disadvantages: It is very difficult to fully master this method, and a lot of exercises need to be performed during the learning process.

6. "Small helicopter" method

Using the same movements when floating, lying on the back of the back, lying back on the water, and immediately began to draw the circle with both hands, and the legs stepped up and down at the same time.

Advantages: Simple movements, children easy to understand.

Disadvantages: Continuously drawing in your hands will make people feel tired.

Floating technique in water

1. Use your hands and feet

Make sure your body and limbs are vertically upward from the water surface.If you hit your body horizontally and start kicking and paddling with your feet in the water, it is already a swimming movement, and no longer stepping on the water.

2. The head faces up, breathe normally

Keep your head above the water and try to breathe slowly and regularly.Slowing your breathing is to allow you to relax calmly and store your physical strength to step on the water longer.

3. The arm swing in the horizontal direction

If you move your arms up and down, it will drive your body to float up and down, because your arms are connected to your body.The correct method is to move the arm in the horizontal direction, move together with five fingers, draw forward the palms forward, and the palm of the palm backward, so that your upper body will keep up and not sink.

4. Draw your legs or kick your legs back and forth

If you choose your legs to draw a circle underwater, you should not be stiff or stiff at your toes or feet; if you choose to kick your legs back and forth, your toes must be kept down, and the movement of kicking back and forth cannot be interrupted.

5. Lie on the water on the back of the back, and at the same time gently scratch your arms and feet

If you want to rest for a while, you can lie on your back and lie down on the water, but your limbs still need to be continuously padded, but you don't have to scratch and work hard as you step as much as vertically.

6. You can use any floating equipment

A wood, a short paddle, and even a rubber boat, as long as it can float on the water, you can use it.You rely on consuming your physical strength, not external forces, and the less time you don't sink, the longer you can float on the water.

precautions for swimming training

1. Overcoming shy psychology, not afraid of people jokes.

2. Properly strengthen physical flexibility exercise.

3. In addition to paying attention to imitation movements, we should also understand its principles.
