Tennis rackets are designed to withstand active use on the court, absorb sunlight, water droplets and cope with a tennis ball that hits the racket at high speed. Strings are the most important part of a racket, and if you take care of them, it will positively affect the quality of your game and the durability of the racket. Depending on your playing style and how often you use the racket, it is important that you re-tension the strings on the racket at least twice a year. From this article, you can learn how to prepare a racket for hauling strings and apply the right hauling technique.
Why do racket strings move?
Choosing between hard and soft stretch, build on your ability to consistently deliver powerful blows. A soft stretch in combination with a small force on impact gives a trampoline effect, the speed of the ball during departure will be higher. Also, with a soft degree of tension on the string surface, the game spot slightly increases. In turn, this allows you to control the ball, which was not received at the center of the racket.
Often beginners notice the displacement of strings on their rackets and are perplexed: Why are racket strings shifted so often? If this happens literally from the first feed, the answer is one - the wrong choice of tension.
Determine the ideal tensile force
So, you became the owner of a balanced and high-quality racket, understand how to choose strings for a tennis racket. Now it’s time to determine at what effort the strings need to be pulled. Carefully inspect your new work tool. Manufacturers usually place recommendations on the inside of the neck of the racket. It is worth noting that manufacturers when creating their products organize tests, involving real players in them. This helps them determine the range of stiffness.
In the recommendations, you will find a range in which you have to find the ideal number of kilograms for a tension machine. The logical option is to first try the value from the middle of the range. If it does not fit, then move in the direction of decrease or increase. With such a strategy, the process does not take much time. For example, if you have 23-27 kg in front of you, try to set the force to 25 kg first. After checking the racquet on the court, you will more accurately understand how to stretch the strings of the racquet - weaker, stronger, or leave it as it is.
Different rackets - different tension
Depending on the racket, your feelings during the game will change, because each of them has different gaming characteristics. Remember that even when you have found the optimum stiffness on one racket for yourself, blindly installing it on another will be a serious mistake. The manufacturer's recommendations are highly likely to differ, and, therefore, the stiffness that is familiar to you on one racket will feel completely different.
If after buying a new racket you feel discomfort and disappointment after playing, try different variations of string tension. You will be pleasantly surprised by the changes in the characteristics of the racket even after minor adjustments to the string tension stiffness.
Banner depending on the type of strings
With strings made from different materials, exactly the same story as with rackets. The optimal tension of nylon strings does not guarantee the same characteristics with Kevlar or, for example, natural strings. The properties of the materials used to create the strings differ from each other at times. Kevlar needs to be pulled 20% less than nylon and nylon 10% stronger than polyester.
First you should choose a special machine for hauling
Many sports clubs and specialty shops offer various string tensioners. The hauling service can cost from 25 to 50 dollars per unit, and the machine itself - from 200 to several thousand dollars (depends on its quality indicators).
If you often play tennis, you can save some on the strings and buy a tapping machine for this money. One of the most popular modifications - Gamma X-2 - is installed on the surface of the table and fixed in two places. For players who decide to independently draw veins, this option will be more preferable in terms of quality and cost.
If you are fond of tennis only occasionally, investing in a machine for personal use will be irrational. It is much more profitable to use a one-time paid service or to borrow a device from friends.
About 10 cm of a new core are cut from the coil. A total of 11 m strings may be needed to tension the strings on a regular racket. You need to cut it off with a small margin so that you do not have to throw it away later if there is insufficient length.
When pulling the veins for the first time, remember which length was required - this will help with the next constriction. Start with the longest string to determine the optimal length.
Securing a racket in a hauling device
The method of fastening will depend on which machine is used. Having installed a racket in the device - its neck and head need to be strengthened in a vice and tightly clamped. After studying the instructions, you should adjust the degree of tension of the cores.
A fixing system with 6 fixing points will allow you to distribute the tension as evenly as possible. When using any type of machine, make sure that all the clamps on the racket are firmly fixed. In order not to bend the rim of the racket, but not to weaken at the time of the game, the strings should be moderately tight.
When the preparatory steps are completed, it is time to proceed directly to the tension.
Choice of a method of hauling strings
There are two tension systems: the same strand can be used for vertical and horizontal positioning, and you can use two different ones. Experts believe that one-string hauling can improve playing ability and significantly extend the life of a racket, but a two-string stretch will be more correct and, accordingly, most acceptable.
It should be noted that the tension should start from the end of the racket with a gradual movement to the handle. This is explained by the fact that the racket can bend, because the place at the handle is weaker than at the head. Therefore, the process should begin from above, moving down. It will be not so simple to do this with one residential building, and sometimes it is impossible.
Hauling the main string
The main core is parallel to the longitudinal axis. At the end of the racket there are holes through which it is necessary to stretch the string towards the handle and then back to the end.
The end of the core must be fixed on the handle and move the rod to a horizontal position. In this case, it may be necessary to change the length of the string. Next, you will need to fix the rod and tighten the core.
The second clamp fixes another core, the first one is uncoupled. Threaded with further clamping until all openings are engaged. Thus, the vein hauling technique is based on the principle: the next string is fixed, and the previous one is released.
Having stretched the final line of vertically arranged strings, the main one is tied and then there follows a broach of wires located transversely. The string extends through the slots (as a rule, the lateral ones are larger) towards the back of the rim and fixed. It is necessary to tighten the core in moderation (without kinks of the racket and weakness of tension). This should continue until all the strings are set.
If the hauling technique involves the use of two strings, the transverse vein is tied at the head to the main string. Then it is pulled through a hole located at the edge of the rim.
It should be ensured that the strings placed across do not rub much on the main ones.
Determination of the desired string tension
On racquets often indicate the parameters of the recommended voltage. The indicator ranges from 23 to 32 kg. In this range, players can independently adjust the tension of the strings to adjust the active spot of the racket, thereby forming the playing ability that is most suitable for their serving style.
To the best of their ability, the tight tension of the cores will help to better control the ball, increasing contact with it and improving the accuracy of serving. With an individual style involving a strike with great force, it is recommended to stretch the wires a little weaker. Try different options for the voltage of the cores - this will help determine the most optimal tension that suits your playing style and racket.
Nylon cores are the most popular, having the most affordable cost, high impact elasticity and sufficient flexibility.
Synthetic and Kevlar strings are perfect for players who have a power strike that can tear ordinary wires. Maximum strength provides the necessary degree of ball control and the ability to take hits of sufficient strength.
Natural strings are prone to brittleness, but are highly popular among professional tennis adherents due to their plasticity and good contact with the ball.
As functional additions, safety and shock-absorbing parts for strings can be used. Small polymer plates placed at the intersection of the cores can extend the life of a tennis racket, protecting the strings from abrasion. Lovers of top feed with a twisted ball add convenience built-in dampers among the cores that weaken the strings and increase the torque of the ball. Additional details are recommended to be tested in practice. Perhaps this will significantly improve the quality of the game.
String hauling regularity
It is recommended that you change strings as many times a year as many games you play in one week. If one of the cores suddenly breaks, this may indicate that it is time to haul the entire racket. Timely replacement of strings eliminates the possibility of unexpected breaks. For players who have a hit of increased strength, the strands on racquets should be changed much more often than those who prefer regular serve.
The functional capabilities of a racket depend on the conditions under which a racket is stored. An effective game can be provided only by a racket that has proper care - storage in a cool, dry place and timely string change.
To extend the life of tennis cores, it is recommended to use fuses - small plates that are installed to reduce friction at the intersection of strings.
To replace the strings you will need such materials:
Follow these recommendations, and you can easily cope with the replacement of strings on a tennis racket yourself.
