Some tennis players and specialists are wary of poly tennis strings. There are articles and opinions that poly strings are injurious to junior arms, and strings’ manufacturers advise lower tensions. It is always more useful to get independence expert’s opinion on this topic.
When it comes to tension, the general rule is to string elastic materials like nylon or natural gut around 50-60lbs, which we’ll use as our base recommended tension. If using a stiffer string material like polyester, we’d recommend stringing looser to avoid arm injuries.
Whenever a tennis racquet is strung, be it at the factory to be sold as a pre-strung frame or by your local stringer, a specific tension is applied to both the cross and main strings. This tension measures weight being applied to the string as it’s pulled through the racket by the stringing machine and expressed in either kilograms or pounds.
20-27 kg / 45-60 lb. You may also find some of the tennis strings you purchase offer a recommended tension range. For example, Babolat’s RPM Blast recommends 48 – 66 lbs or 22 – 30 kg, a rough guide for understanding where they have determined the string performs its best.
Low String Tension . A low string tension would be anywhere from around 40-50lbs. There are exceptions, of course; some players even going below 40lbs! That end of the spectrum is pretty much trampoline territory and we’ll get on to that later! But let’s lay out some facts first. Stringing your racket at a low tension will give you: MORE Power
At an early stage of competition, it is often better to stretch your racquet "reasonably", between 23 and 27kg to maintain control and, most importantly, avoid injuries. "Extreme" tension, below 23kg or above 27kg, is often difficult to master and requires some dexterity. And can, moreover, quickly tire your arm.
String Tension. The string tension can be as equally as important as the string itself. Most junior tennis rackets recommend a string tension of between 45lbs and 55lbs. As a rule, a lower string tension will generate superior power. While a higher tension will demonstrate more control, but also more vibrations and strain on the arm.
A: Depends on your playstyle and the type of string you have. Higher tensions will often result in more control, while lower tensions will result in more power. Exception is polyester strings which should always be strung 10-20% lower than your normal tension preference. Thanks Vincent for talking with me today.
