How to choose and maintain table tennis bat, we all know that table tennis is a very noble thing for us and a symbolic ball game in China. So many friends like table tennis, so here's how to choose and maintain table tennis bats.
How to choose and maintain table tennis bat 1 table tennis bat selection
There are many styles and ways of table tennis, and players will choose the appropriate table tennis bat according to their own styles. This is conducive to their own play.
The preferred grip method is generally divided into two types: straight shot and horizontal shot. When table tennis came into being, Europeans imitated the grip of tennis racket and basically adopted the horizontal racket. Later, table tennis developed to Asia, resulting in a direct grip racket.
It is said that the difference between horizontal and direct shooting is determined by the different eating habits of Europeans and Asians. European tableware is mostly knives and forks, which are used to being held horizontally. Asians use chopsticks more often and are used to holding them directly. This statement is not unreasonable, but the choice of racket is closely related to factors such as playing style and physical condition.
European players are generally tall and burly, with a wide range of physical exercises, and COSCO Taiwan Province has obvious advantages. In this case, the choice of horizontal play is more conducive to attack.
Asian players, represented by China people, are generally short in stature and have a small platform protection area, and COSCO Taiwan Province Mobile is not as big as European players. However, Asians are quick-witted and quick-witted, especially when dealing with Taiwan Province's balls. Choosing backhand can give full play to their advantages, such as variety and flexible wrist movements.
Of course, this is only in terms of the basic characteristics of Eurasian people, which may not be applicable to everyone.
What kind of rubber?
Positive glue sponge bat
Positive glue is rubber with rubber particles facing upwards and the same height and diameter. This is the most traditional racket for China athletes.
All previous world champions have chosen rubber sponge rackets for competitions. Compared with other kinds of rackets, rubber sponge rackets are characterized by better elasticity and faster hitting speed.
Therefore, it is suitable for players who are close to Taiwan and fast-break. It is not easy to eat all kinds of spins, and it is precisely because of the low viscosity that it is not easy to make strong spins. Therefore, although the glue racket can't pull out the powerful loop ball, it can use the rotating ball and forehand volley of the processing table.
If you think your wrist is flexible, but your arms and waist are not strong enough, you'd better choose a rubber racket that wins with speed.
Raw rubber sponge bat
Raw rubber is rubber with upward particles and a diameter greater than the height. It is characterized by the ball sinking and weak rotation, which is suitable for players near the table.
Because raw rubber can reduce rotation, it is especially easy to control the ball. Especially when backhand plays short ball in the table, it is handy to take the initiative in a short time by using backhand raw rubber and save physical strength at the same time. However, a group of female players in South Korea are unique, playing raw rubber with their hands straight, getting started quickly and preemptively, which is a great threat.
Anti-sticking sponge bat
Anti-sticking is a kind of rubber, which sticks down and has a sticky smooth surface facing up. This is the most common racket now. Almost 65,438+0,000% of European players use this rubber, and nearly 80% of Asian players use it.
The spinning power of the anti-glue ball is very strong, so players who mainly play with spinning (such as curling and chopping) must be familiar with this skill. The contestants are all anti-glue. Of course, reverse glue is easy to spin, easy to eat and difficult to master.
Defensive sponge bat
Generally speaking, the defensive technique is mainly chopping, and it also belongs to rotating play. Therefore, the backhand is full of flowers.
Positive backhand, cutting the ball between turning and not turning, changes with the rotation strength of the incoming ball, which often makes the opponent's judgment wrong.
Long rubber for backhand, which is rubber with upward particles and diameter less than height. The rotation changes greatly. The more the opponent pulls the ball, the more the ball is cut back, and the ball sinks, so it is not easy for the opponent to use it.
Dumbbell fitness can not only consume excessive calories and lose weight, but also strengthen the body and train muscles. But many fitness people only know the benefits of lifting dumbbells, but they don't know what the correct dumbbell exercise method is. Introduce the method of lifting dumbbells and tell everyone that different dumbbell lifting postures have different effects on the whole body muscle exercise.
Basic methods of lifting dumbbells
Everyone knows that exercise helps to lose weight. Most people choose aerobic exercise such as jogging, walking and dancing. American fitness experts believe that the best way for women to lose weight is to lift weights.
Some experts believe that lifting dumbbells is also a way to lift weights, and if female friends can carry out dumbbell lifting training at least three times a week and lift dumbbells for 20 minutes every day, they can help maintain the speed of metabolism, thus achieving the goal of really losing weight. Here are some ways to lose weight by lifting dumbbells.
Hold the bell and bend your elbow.
Stand with your feet shoulder width apart, hold dumbbells in your hands, put them in front of your thighs, and put your fists outward. The upper body is upright, the shoulders are still, and the elbows are alternately bent for 20 to 40 times. During the exercise, don't flash back and forth at the waist, and the upper arm should be slightly attached to both sides of the chest.
Lie on your back and bow your head
Stand with your feet shoulder width apart, hold the dumbbell up, and put your fist back. Elbows are alternately bent to the back of the neck for 20 to 40 times. When you bend your elbow behind your neck, your abdomen can't protrude forward.
Body side winding ring
Stand with your feet slightly wider than your shoulders, hold dumbbells and put them outside your chest, with your palms slightly upward and your elbows slightly bent. The arms are wound from inside to outside or from outside to inside simultaneously or alternately for 20 ~ 40 times. The upper body must not rotate with it during practice.
Precursor and afterbody
Stand with your feet slightly wider than your shoulders, hold dumbbells, put them behind your neck, and move your elbows forward slightly. Continue to do forward and backward bends for 20 ~ 40 times. When practicing, keep your legs straight. When bending, hold your chest out and slightly expand your abdomen.
Left and right lateral bodies
Stand with your feet shoulder width apart, hold dumbbells, put them on the outside of your thighs, and rush your eyes forward. Continue to bend your body alternately from left to right for 40 to 70 times. When bending to the left, raise your right arm and bend your elbow, and extend your left arm as far as possible to your left calf. When practicing, keep your legs straight and don't lean forward.
pay attention to
When training dumbbells, you should do what you can. Choose dumbbells with appropriate weight when practicing. Don't push too hard, so as not to hurt your body. You don't have to do all the above methods, you can do two or three of them. The amount of exercise, exercise frequency and time can be gradually increased and mastered flexibly.
Dumbbells can exercise the whole body muscles.
Small dumbbells can exercise most of your muscles. The fitness instructor said: Compared with barbell exercises, dumbbell exercises need more balance and coordination. Moreover, dumbbells don't need to spend a lot of money to buy large pieces of fitness equipment to occupy a lot of space, and they don't need to go to the gym every day. Small dumbbells can exercise most of your muscles.
Exercise your shoulders
All kinds of dumbbell exercises can exercise shoulder muscles. For example, use dumbbells to do side lifting, front horizontal lifting, bending birds, and develop the middle bundle, gallbladder bundle and back bundle of shoulder deltoid muscle. To develop trapezius muscles, you can shrug your shoulders with dumbbells or practice in circles.
Exercise your lower back
Dumbbells are easier than barbells, which can reduce the excessive pressure on the spine, and you can also practice biceps femoris by pulling hard on your legs.
Offenders often use defensive sponges to make up for backhand. They use defensive sponges, which are similar to anti-sticking and non-sticking. The hitting power is weakened and the sinking is erratic, which makes it difficult for the opponent to judge according to the routine, especially when reading the ball in an arc, so it is called "anti-arc glue".
For beginners, you usually take the racket of your favorite athlete as a model for beginners, and make corresponding changes with the development of your own technology and your own characteristics. This is a common way to choose a racket.
Many table tennis fans have a personalized table tennis bat tailored for themselves. In the table tennis match, your table tennis bat can be regarded as a comrade-in-arms. So, how to prolong the service life of your "comrades-in-arms"? Let's talk about how to maintain the table tennis bat.
Table tennis racket maintenance
1. During use, in addition to keeping the bottom plate in a dry place to prevent heavy pressure and damage, special attention should be paid to the collision between the ball board and the table top and the ground during playing. For example, when a plurality of balls are fed, a spare board can be used.
Chopper players should keep a certain distance from the ground when practicing, and should avoid the invasion of bad habits such as deliberately throwing the racket, hitting the table with the racket and hitting the baffle.
2. The main factors that affect the properties of sponge are thickness, hardness, elasticity, pore size and pore number. Because sponge is an expanding body, it should not be excessively pulled and stressed during use. When playing in a low temperature place, you should pay attention to proper heat preservation, because the bottom temperature will affect the elasticity of the sponge.
People who use a single piece of rubber sheet and sponge sheet should use a fire-roasting electric perm head to iron the rubber sheet when replacing the rubber sheet, so that the glue between the rubber sheet and sponge can be fully dissolved and the sponge can be prevented from being damaged when replacing the rubber sheet. Glue can make the sponge foam and increase its elasticity, but when sticking to the bottom plate, use non-toxic special glue, which can protect both the sponge and the bottom plate.
3. There are many kinds of rubber covers in table tennis tools, but they can be roughly divided into two kinds, one is reverse stickers and the other is positive stickers.
Reverse stickers include reverse glue and arc-proof glue, while front stickers include positive glue, raw glue and long glue. Because of the different rubber content, the reverse rubber has large friction, strong surface adsorption and adhesion, and the contact point between rubber and ball is not easy to slide, which is beneficial to increase the rotation of ball.
In order to give full play to this characteristic, the most important thing when using reverse glue is to keep the rubber clean. Don't rub the eraser with greasy hands. After playing the ball every time, you can rinse the rubber with clear water and paste a layer of plastic film. If there is dirt that is difficult to remove with clean water, it can also be cleaned with detergents such as soap and dried before use.
The front rubber is low in rubber content, high in tooth hardness, low in friction, small in area and easy to slide because the rubber is in contact with the ball. Based on this feature, special attention should be paid to keeping the rubber dry when using positive glue.
Why do rackets need to be wet and dry?
1. One of the reasons why the service life of the racket is shortened and the performance is degraded is that the board is affected by humidity. Moreover, this kind of influence is wet air bath from the day when the racket was born; In the process of gluing, there is a corrosive agent of glue; It exists in the process of playing, and the sweat is tightly immersed; During the idle process, it may be accidentally touched by rain, drinks or other liquids.
In short, the racket will be tested and tortured by nature and man-made from the day it is freshly baked. In this process, if the performance of the racket decreases and the weight increases due to long-term moisture (like people suffering from rheumatism, it is very necessary to dehumidify the racket scientifically).
The electric hair dryer can only play the role of instantaneous air drying, but its high-temperature drying method will cause the laminated adhesive to crack easily, thus damaging the racket. Moreover, because the wet wood in the racket can't be dried in time, it will be moldy and rotten after a long time. Thereby reducing the performance of the racket, reducing the hitting force and making the sound dull.
2. When you don't play for a long time, use dehumidification box to dehumidify and dry the racket. Through the slow but powerful dehumidification function of silica gel, the whole racket is completely dried, achieving the dry, light, crisp and transparent sound effect when the racket was just born before leaving the factory.
More beautiful than when I bought it. Achieving this effect for a long time can at least effectively prolong the service life of the racket. Especially for your favorite racket, you should cherish it.
Matters needing attention in maintenance
1, don't be close to high temperature, to avoid that the sponge and rubber heated by table tennis bat are easy to age and reduce their viscosity and elasticity, commonly known as "death". The board is also easy to deform after being heated, which affects the accuracy of hitting the ball.
2. Avoid contact between sponge and rubber. Rubber products will be deformed and deteriorated once they come into contact with gasoline, so special attention should be paid to it.
3. Prevent abnormal external forces from rubbing, bumping and squeezing to hit the ball with correct actions, and the racket will not bump against the table. When the racket is not in use, it is best to put it in a special racket case, and at the same time put a flat plate made of wood or plastic in the racket case to minimize the influence of external force on the racket.
4. Keep the racket surface clean. Once there is dirt on the rubber surface, the viscosity will be greatly reduced. At this point, you can gently wipe the glue racket with a clean cloth and water. Wipe the ball with a soft cloth after the anti-adhesive racket has finished playing. Be sure to avoid scratching the rubber surface, and finally stick a layer of nylon paper or a thin soft plastic sheet on the surface.
5. Every time the racket is used up, it's best to clean it with cleaning agent and stick a film on it.
Table tennis bat handle
The grip of table tennis is basically divided into two types: direct grip and horizontal grip. Different grip methods have different advantages and disadvantages, resulting in different styles of play.
Direct-shot fast attack grip
1, beat the hand with the second knuckle of the index finger and the first finger of the thumb before shooting. The distance between thumb and forefinger should be moderate.
2. After the beat, the other three fingers naturally bend, and the first knuckle of the middle finger is attached to the back of the beat.
Loop ball grip
1. Before shooting, put your thumb close to the left side of the handle, and buckle the handle with your forefinger to form a small ring to hold the handle tightly.
2. After shooting, the other three fingers naturally straighten, and the first knuckle of the middle finger leans against the middle of the back of the racket.
Straight-shot chop grip
1, bend your thumb close to the left side of the racket handle before the racket, and press the racket hard.
2. After hitting the ball, the other four fingers naturally separate and hold the back of the ball.
3. When forehand chopping the ball, the forearm rotates to make the racket lean back. When backhand chopping, the four fingers shake the racket up flexibly after the racket, so that the handle is down.
tennis grip
1, middle finger, ring finger and little finger naturally hold the handle.
2. The thumb is lightly attached to the middle finger on the front of the racket, and the index finger is naturally straightened and placed obliquely on the back of the racket.
3. When holding lightly, the tiger's mouth is slightly attached to the racket, and when holding deeply, the tiger's mouth is close to the racket.
Summary: Table tennis is the national sport of China, so as a China person, we should all know something about it. In many teenagers' spare time activities, some table tennis competitions will be held. Basically, everyone has their own ping-pong bat. The selection and maintenance of table tennis bat and the correct grip method are introduced above. I hope I can help you exercise better.
How to choose and maintain table tennis bat 2. Maintenance of table tennis bat
1. During use, in addition to keeping the bottom plate in a dry place to prevent heavy pressure and damage, special attention should be paid to the collision between the ball board and the table and the ground during playing. For example, when feeding more balls, you can use the spare board, and the chopper should keep a certain distance from the ground when practicing. More importantly, they should avoid deliberately throwing their rackets, hitting the table and hitting the baffle with their rackets because of losing.
2. The main factors that affect the properties of sponge are thickness, hardness, elasticity, pore size and pore number. Because sponge is an expanding body, it should not be excessively pulled and stressed during use. When playing in a low temperature place, you should pay attention to proper heat preservation, because the bottom temperature will affect the elasticity of the sponge.

If there is dirt that is difficult to remove with clean water, it can also be cleaned with detergents such as soap and dried before use.
4. The front and rear rubber sleeves have low rubber content, high tooth hardness, small friction and small area, and the rubber sleeves are easy to slide when contacting the ball. Based on this feature, special attention should be paid to keeping the rubber dry when using positive glue. If you play in a wet place, you can wipe the rubber with a desiccant to reduce the humidity on the rubber surface. Generally speaking, the bottom cover of rubber sheet is relatively thin. When sticking with a sponge, don't apply too much glue on the rubber at a time to prevent the rubber from being "rolled" and causing unnecessary losses.
The rules of table tennis bat stipulate that
(1) The size, shape and weight of the racket are not limited. But the bottom plate should be flat and hard. The floor thickness should be at least 85% of natural wood. Strengthen the adhesion of the bottom plate, use fiber materials such as carbon fiber, glass fiber or compressed paper as far as possible, and the adhesion of each layer shall not exceed 7.5% or 0.35 mm of the total thickness of the bottom plate.
(2) The racket face used for hitting the ball should be coated with a layer of "ordinary particle glue" with outward particles, and the thickness of the glue should not exceed 2mm or covered with "sponge glue" with inward or outward particles, and the thickness of the glue should not exceed 4mm. The "ordinary particle glue" is a layer of natural rubber or synthetic rubber without foam, and its particles must be distributed on the whole surface, with an average density of not less than 10 and not more than 50 particles per square centimeter. "Sponge rubber" means that a layer of foam rubber is covered with a layer of ordinary granular rubber, and the thickness of ordinary granular rubber is not more than 2mm.
Many people like running for fitness, which is not only convenient but also effective. However, running in an incorrect posture can easily hurt us. Only by using the correct running posture and knowing how to warm up before running can we run and keep fit better. It is also important to adjust your breathing while running. Learning to breathe can relieve the pressure of running on the body.
Do you have seven incorrect running poses?
1, striding makes the muscles in a state of low stretching efficiency, causing the feet to land in front of the knees, thus generating braking effect. You will feel as if the ground is heavy, and your feet touch the ground in front of your knees.
2, the action of wasting physical strength, too much up and down exercise wastes physical strength. The biggest reason is that the knee lift is too high or the stride is too small. You will feel as if you are running in the same place instead of running forward, so you may have problems with tight calves or injuries. Crossing the swing arm in front of the trunk to hinder the forward movement is another example of wasting physical strength.
3. Excessive pressure inside the arch will bring extra pressure to the muscles supporting the arch, and then pull the muscles attached to the medial tibia. So the knees are pronated and become nervous. The gluteal muscles are in an inefficient state due to knee pronation, which causes tension in the gluteal flexors and back and pelvic inclination.
4. Sit on your hips. This posture is that the pelvis leans forward and the hips retract, which will reduce the strength of the hamstring and gluteal muscles. This is usually caused by weak key muscles, poor pelvic adjustment and tense hip flexors, but fatigue during running can also lead to this posture. This may lead to many back and hip diseases.
5, the soles of the feet are too everted, the soles of the feet are not too pronated, but the pronation is not enough, staying at the outer edge. This weakens the ability of the sole to absorb the impact force and increases the risk of stress fracture.
6. The driving force of hip joint is insufficient, and relying too much on quadriceps femoris (anterior thigh muscle) and gluteus flexor muscle instead of hamstring (posterior thigh muscle) and buttocks will reduce the stride distance and weaken the stride strength. Try to swing back and forth.
7, hip sinking, this is the improper method of landing on the ground, which may lead to diseases on the back and outside of the legs.
Learning to adjust breathing and running is better.
Take a deep breath before running
Before running, breathe in enough air through your nose, then hold your breath for 5 seconds and then spit it out slowly, so that breathing can make your body enter the best state of exercise.
Breathe rhythmically while running.
It is difficult to master the breathing rhythm during running, and many friends who often run can't master it well, but if you can master it well, you can coordinate the relationship between exercise and breathing well. Many long-distance running world champions use this method to exercise, such as running three steps to inhale or exhale; If you run fast, you can run two steps at a time and one step at a time. However, if this breathing rhythm makes you feel difficult to breathe, you can take a step every time you inhale or exhale.
Jogging can inhale for 5 seconds and exhale for 5 seconds. When running, the shoulders, wrists, hands and chin are all in a state of tension, and the process of exhaling is a relaxing process, so shaking hands, shoulders and mouth can relieve the pressure on the body when exhaling.
(3) The covering should cover the whole racket face, but not beyond its edge.
(4) The bottom plate, any interlayer, covering layer and adhesive layer in the bottom plate shall be a whole with uniform thickness.
(5) Both sides of the racket, whether covered or not, must be dull, with one side bright red and the other black.
(6) Due to accidental damage, wear or fading, the integrity and color consistency of the racket face are slightly different. As long as the performance of the racket face has not changed significantly, it can be used.
(7) Athletes should put their rackets on the match table at halftime, except with the special permission of the referee.
(8) The spherical plate cover can be bonded with pressure-sensitive adhesive tape or other adhesives approved by ITTF.
The benefits of playing table tennis often.
1, insisting on playing table tennis can arouse our emotions, exercise can keep us happy, and playing table tennis can be a good vent if we encounter unhappy things. Of course, playing table tennis can still make friends with the ball, which will make us make many good friends.
Some friends don't know that playing table tennis is good for our eyes. In fact, insisting on playing table tennis is very good for our eyes. This is because table tennis is faster, so our eyes should keep up with it in time, which can not only relieve eye fatigue, but also protect our eyesight and prevent myopia.
3. In all sports, the speed of table tennis is relatively fast, so when playing table tennis, we should make a judgment in the shortest time, and make an accurate judgment on the change of the ball and the route of the ball. In fact, this has greatly improved our thinking and sensitivity.
4. Many times playing table tennis consumes our physical strength, which is of course very helpful to increase our appetite and promote our gastrointestinal peristalsis.
Playing table tennis is a very pleasant thing. This sport is very suitable for children, and many middle-aged and elderly people also like to play table tennis. In fact, to play table tennis, we not only need to keep an eye on six ways and use our brains, but also need our quick response and quick pace to play more flexibly. It is also very helpful to our coordination and makes us full of vitality.
Conclusion: The above details about the maintenance of table tennis bat and the rules and regulations of table tennis bat. I hope you can learn more about this knowledge about table tennis. My main purpose is to hope that everyone can have a clear understanding of table tennis, like it and stick to it.
