A sore elbow after a long match can make string tension seem like the obvious culprit. It may be part of the problem, but there is no single “safe” number: string type, racquet, technique, playing volume and existing injuries all matter. A good setup can make impact feel more comfortable, but tension alone cannot prevent an injury.
What tension can—and can’t—do
String tension is the force used to pull the strings tight during stringing. Within a racquet’s recommended range, lower tension generally lets the string bed deflect more at impact, which many players experience as a softer, livelier response. Higher tension usually feels firmer and more controlled. Those are useful playing differences, not a guarantee of what any player’s arm will feel.
Comfort also depends on the strings themselves. A stiff polyester string can feel demanding even at a relatively low tension, while a more elastic multifilament may feel forgiving at a higher one. Racquet stiffness, weight, balance, grip size and string condition add further variables. That is why simply dropping tension by ten pounds is not a reliable treatment for tennis elbow.
There is a trade-off, too. A very loose setup may feel comfortable but launch the ball higher or make control harder for some players. If that leads to late contact or extra effort to keep the ball in, the change may not help your arm overall. Look for a setup that feels comfortable and lets you swing freely.
How to make a sensible tension adjustment
- Check your racquet’s tension range. Use the manufacturer’s recommendation as a guardrail, and ask your stringer how their machine and practice affect the result. A number on one machine may not produce exactly the same feel on another.
- Identify the string before changing the number. If you use a stiff polyester and have arm discomfort, trying a softer string—or a hybrid with a softer cross string—may be more useful than making a large tension change.
- Change one thing at a time. Start with a modest adjustment, such as lowering tension by two or three pounds, or changing string type while keeping tension similar. Keep the racquet and setup consistent enough to judge the difference.
- Test it in ordinary hitting first. Note comfort, ball launch, control and whether you are swinging freely. Give the setup a few sessions if it feels manageable, but do not play through worsening pain just to complete a trial.
- Record the details. Write down the string model, gauge, tension, date and how it felt. Strings lose tension and change with use, so a comparison is more useful when you know what was installed.
There is no universal tension prescription for an injury. As a cautious starting point—not a medical recommendation—many recreational players using multifilament strings might test somewhere around 48–54 pounds, provided that is within their racquet’s range. Players using polyester often try lower tensions, but polyester can still feel firm; switching to a softer string may be the more relevant experiment. Follow the racquet maker’s limits and ask an experienced stringer to help tailor the setup.
Comfort-oriented strings worth considering
These are distinct options to discuss with a stringer, not injury treatments. Suggested tensions are only starting points for a trial, assuming they fit your racquet’s range and your preferred response.
| String | Type | Why consider it | Trade-off | Possible trial approach |
|---|---|---|---|---|
| Wilson NXT | Multifilament | A comfortable, accessible alternative for players moving away from full polyester. | Usually costs more than basic synthetic gut and may fray or lose feel sooner for heavy hitters. | Start near your usual tension, or a few pounds below if the string bed feels too firm. |
| Head Velocity MLT | Multifilament | A versatile option with a comparatively controlled response for a multifilament. | Still won’t match polyester’s durability for frequent, hard-hitting string breakers. | Try a small drop from your current tension rather than making a dramatic change. |
| Tecnifibre X-One Biphase | Premium multifilament | Known for a lively, cushioned feel that may suit players prioritizing comfort and power. | Can be expensive, and the added liveliness may take adjustment if you normally use a firm setup. | Begin around your normal multifilament tension; assess control before lowering further. |
| Yonex Rexis Comfort | Multifilament | A comfort-focused option for players who want a softer alternative to polyester. | Like other softer strings, it may be less durable for frequent topspin hitters. | Ask the stringer to keep tension close to your familiar setup for a clean comparison. |
| Wilson Sensation | Multifilament | A more budget-conscious route to a softer string bed than full polyester. | May not hold its playing characteristics as long as premium alternatives for some players. | Use a modest adjustment and judge both comfort and launch angle over several sessions. |
These strings differ in feel, price and durability, and none will suit everyone. Gauge matters as well: a thinner string can feel livelier but may break sooner. If you are unsure, ask your stringer to install one racquet with the new setup while leaving another unchanged. That gives you a practical comparison without relying on memory.
When tension is not the main issue
If discomfort continues, consider the whole setup and workload. A racquet that is too light or poorly matched to your swing can feel unstable at impact; a grip that is too small or too large can also affect how you hold the handle. Fresh balls, a different hitting surface, a sudden jump in playing hours, or repeated late contact may contribute to irritation. A coach or qualified stringer can help assess equipment and technique, but neither a softer string nor a tension adjustment diagnoses an injury.
Do not use equipment changes to mask pain that is worsening, affecting daily activities or lingering after play. Stop or reduce the activity that aggravates it and seek advice from a healthcare professional, especially if symptoms persist or return each time you play. If a clinician gives you specific guidance, follow that over a generic string recommendation.
Frequently Asked Questions
Does lower tension prevent tennis elbow?
Not reliably. Lower tension can make a string bed feel more comfortable to some players, but it does not guarantee injury prevention. String type, racquet, stroke mechanics and playing load also matter.
Should I switch from polyester if my arm hurts?
It may be worth testing a softer multifilament or a hybrid, particularly if you use full polyester and do not need its durability. If you are in pain, however, changing strings is not a substitute for reducing aggravating play or seeking medical advice.
How much should I lower my tension?
Try a small change—often two or three pounds—rather than making a large jump. Stay within the racquet maker’s recommended range, and change only one variable at a time so you can judge the effect.
Can I keep playing if a softer setup feels better?
A more comfortable feel is useful feedback, but it does not prove that an injury has healed or that the setup is preventing one. Increase playing time cautiously, and stop if pain worsens or persists.
Final Thoughts
For a more comfortable tennis setup, consider string type before chasing a particular tension number. Make modest, trackable changes, stay within your racquet’s limits and judge comfort alongside control and effort. If arm pain persists, treat it as a health issue—not just a stringing problem.
