Quick Answer: Tennis elbow in recreational players is usually a load problem, not a technique problem. The three highest-yield checks are grip size (too small forces you to squeeze harder), string tension and string type (stiff polyester at high tension transmits far more shock), and total weekly playing volume including the sudden jumps that happen in league season. Fixing your backhand is the most commonly given advice and rarely the fastest fix.

You get told it’s your backhand. So you spend six weeks rebuilding a stroke that was fine, and the elbow still hurts on the third game of every match.

The elbow is responding to accumulated load on the tendons that extend your wrist. Technique is one input into that load. It is usually not the largest one, and it is almost never the one you can change fastest.

This is general information, not medical advice. Persistent or worsening elbow pain is worth having assessed by a physiotherapist or sports medicine doctor.

What is actually happening in tennis elbow?

The name is misleading in two directions at once, and understanding the tissue explains why the usual advice misses.

Lateral epicondylitis - tennis elbow - involves the tendons that attach your wrist extensor muscles to the outside of the elbow. The main one is extensor carpi radialis brevis. Every time you grip hard, those muscles fire, and every time you absorb an off-centre impact, the tendon takes the shock.

The -itis suffix is now considered inaccurate. Research over the past two decades has consistently found that the tissue in chronic cases shows degenerative change rather than active inflammation - disorganised collagen, increased ground substance, and new blood vessel growth. The term tendinopathy is more accurate, and it matters because it changes what treatment makes sense. Anti-inflammatory approaches address a process that largely is not there in the chronic phase.

Why that changes the plan: if the problem were inflammation, rest and ice would resolve it. Because it is degenerative and load-related, the tendon needs graded loading to remodel - complete rest often produces short-term relief followed by immediate recurrence when you return.

The other misleading part of the name: studies of the condition consistently find that the majority of people diagnosed with tennis elbow do not play tennis. It is common in trades, in office workers with high mouse and keyboard load, and in anyone who does repetitive gripping. Which tells you something important - the tendon does not distinguish between a racquet, a screwdriver and a kettlebell. It only counts total load.

The practical implication for a tennis player: your tennis load is one column in a spreadsheet that also includes your job, your gym work, your gardening and your phone use. If the total exceeds what the tendon has adapted to, symptoms appear - and the sport gets blamed because that is when you notice it.

One more piece of context worth having. Tennis elbow is most common between roughly 35 and 55, and it typically develops in the dominant arm. That age range is not a coincidence - tendon tissue becomes somewhat less tolerant of rapid load increases over time, while recreational playing volume often increases in the same years as schedules free up. The mismatch is the mechanism.

Why does grip size matter more than your backhand?

Because grip size directly determines how hard your forearm has to work on every single ball, and it is a change you can make this week.

A grip that is too small forces you to squeeze harder to stop the racquet twisting on off-centre contact. More squeeze means more sustained contraction in exactly the muscles whose tendons are already irritated. A grip that is fractionally too large is generally better tolerated than one that is too small, which is useful to know because it tells you which direction to err.

The standard measurement: hold the racquet in a forehand grip and check the gap between your fingertips and the base of your thumb. You should be able to fit roughly the width of your index finger into that gap. No gap means the grip is too small. A gap wider than a finger means it is too large.

Why this drifts without you noticing: overgrips build up. Adding an overgrip increases effective grip size by roughly one-sixteenth of an inch, and people who replace overgrips without removing the old one can be a full size or more away from where they started. Conversely, a grip that has compressed with age and sweat effectively shrinks.

The seasonal version of this problem: in humid late summer conditions, players sweat more into the grip and often squeeze harder to compensate for slip. The grip has not changed size, but the required grip force has increased - which is why some players notice elbow symptoms appearing specifically in August and September.

Practical fixes, in order of speed:

• Measure your grip properly rather than assuming the size you bought years ago is still right
• Replace worn overgrips regularly instead of layering, and strip back to the base grip when it gets thick
• Try a tackier overgrip in humidity so you are not compensating with force
• Consider going up one size if you are between sizes and have symptoms

Compared to a technique rebuild, this takes ten minutes and costs the price of a grip. It is the first thing to check and the last thing most players are told about.

How much does string setup change elbow load?

Substantially - and this is the second-highest-yield change available.

Stiff strings transmit more shock to the arm. Polyester and co-polyester strings are considerably stiffer than multifilament or natural gut, and they have become the default for many players because they offer control and spin potential and resist breaking. For a recreational player with elbow symptoms, they are frequently the wrong choice.

Tension compounds it. A higher tension means less string bed deflection, which means more of the impact energy goes into the frame and arm. Dropping tension increases dwell time and softens the impact.

A reasonable experiment for someone with symptoms:

• Move from full polyester to a multifilament, or to a hybrid with multifilament in the mains
• Drop tension by around 4-6 pounds from your usual setting
• Play three sessions before judging - the first session will feel different in ways that are not all about the elbow

Strings also lose tension as they age, which sounds like it would help but does not. Dead polyester goes stiff and loses its resilience, so an old poly job can be worse than a fresh one despite reading lower on a tension meter. Restringing more often, or moving off poly entirely, addresses this.

Frame factors matter too, though they are a bigger purchase. Heavier, more head-light frames with higher swingweight generally transmit less shock to the arm than very light frames, because more of the impact is absorbed by the racquet’s own mass rather than by you. Very light frames marketed as easy to swing can be harder on the elbow, which is counterintuitive enough that most players never consider it.

Balls are a small but real factor. Old, waterlogged or pressureless balls are heavier at impact. Playing a whole summer on the same tired can of balls adds load you did not sign up for.

Ordering these by cost and impact: strings and tension first, grip size alongside it, frame last. The strings are a forty-dollar experiment that changes the shock profile of every ball you hit.

What role does the sudden jump in playing volume play?

It is often the actual trigger, and it is the one nobody logs.

Tendons adapt to load slowly. They respond well to gradual increases and poorly to sudden ones. The classic pattern in recreational tennis is a player going from once a week to three times a week when league season starts, or adding a weekend clinic, or taking a tennis holiday.

The jump does not have to be large in absolute terms - going from one session to three is a 200% increase, regardless of whether that is one hour or three. The tendon responds to the relative change.

Symptoms lag the cause. Tendon pain typically appears days to weeks after the load increase, which is why players usually attribute it to whatever they were doing when it started hurting rather than to the schedule change three weeks earlier. This lag is the single biggest reason the cause gets misidentified.

What to actually track:

• Sessions per week, and any change in the last month
• Hours per session - a two-hour social hit is more load than a one-hour lesson
• Intensity - competitive match play involves more full-effort swings than a rally session
• Surface changes - moving from clay to hard court increases impact
• Non-tennis load - gym pulling work, gardening, DIY, a new job with more typing

The last one is routinely missed. A player who adds heavy deadlifts, rows or kettlebell work is loading the same wrist extensors that grip the racquet. So is anyone who has just spent a weekend painting.

A useful rule of thumb: if you want to increase playing volume, do it in increments of roughly 10-15% per week rather than doubling. It feels slow. It is considerably faster than six weeks off.

What to do if you are already symptomatic: you do not necessarily need to stop. Reducing volume to a level that produces mild symptoms which settle within 24 hours is generally a workable threshold, while you address grip, strings and start loading work. Pain that lingers into the next day means you have gone too far.

What loading exercises actually help - and how long do they take?

This is the part with the strongest evidence and the least patience applied to it.

Eccentric and heavy slow resistance loading of the wrist extensors has the best support in the research literature for lateral elbow tendinopathy. The principle is the same across tendinopathies: controlled, progressive load stimulates the tendon to remodel.

The basic movement: with your forearm supported on a table and palm facing down, hold a light weight and lower the wrist slowly over about three seconds, then use the other hand to help it back up. The slow lowering phase is the active ingredient.

Starting parameters that appear repeatedly in protocols: three sets of around 15 repetitions, once daily, starting with a very light weight - genuinely light, often 0.5-1kg. Progress the weight when the current one becomes easy, typically weekly.

A second useful exercise is supination and pronation work with a light hammer or weighted bar held at the end, rotating the forearm slowly through range. This addresses a rotational component that pure wrist extension work misses.

On discomfort during the exercise: most protocols accept mild discomfort during loading, on the basis that pain-free loading is often insufficient stimulus. Sharp pain, or pain that persists and worsens the next day, means the load is too high.

Timelines are the part people are not told. Meaningful improvement in tendinopathy typically takes 8-12 weeks of consistent loading, and full resolution can take longer. Someone doing the exercises for ten days and concluding they do not work has not tested them.

Grip strength work is worth adding once basic extensor loading is tolerated, because grip endurance reduces how hard you have to squeeze relative to your maximum.

On braces and straps: counterforce braces worn below the elbow can reduce symptoms during play for some people by changing where force is transmitted. They are a symptom management tool, not a treatment - useful for getting through a match while the loading programme does the actual work.

On injections: corticosteroid injections have consistently shown good short-term relief and worse long-term outcomes than exercise-based approaches in the research. That is a genuinely important finding, and it is worth discussing the timeframe with a doctor rather than optimising only for this month.

Myth vs Fact: Tennis Elbow

Six claims worth sorting out.

Myth: You need to rest completely until it stops hurting. Fact: Complete rest reduces symptoms and does not remodel the tendon. Symptoms typically return on resumption because the tissue capacity has not changed - and may return faster, because the tendon has deconditioned. Relative rest plus progressive loading is the better-supported approach.

Myth: It is caused by bad backhand technique. Fact: Technique contributes, particularly a leading-elbow backhand with a late contact point. But grip size, string setup and volume changes are more commonly the primary drivers in recreational players, and they are all faster to change than a stroke.

Myth: It is inflammation, so anti-inflammatories will fix it. Fact: Chronic cases show degenerative rather than inflammatory change. Anti-inflammatories may help pain in the short term and do not address the underlying tissue state.

Myth: A lighter racquet will be easier on your arm. Fact: Often the opposite. Very light frames transmit more shock because less impact energy is absorbed by the racquet’s mass. Heavier, head-light frames with reasonable swingweight are generally more arm-friendly.

Myth: Only tennis players get it. Fact: Most people diagnosed with lateral epicondylitis do not play tennis. Trades, gardening, DIY and heavy computer use all produce it.

Myth: If it has lasted months, it will not get better. Fact: Chronic cases respond to loading programmes, though the timeline is longer - often three to six months rather than eight weeks. Duration of symptoms predicts a slower response, not a failed one.

FAQ: Tennis Elbow Questions, Answered

Can I keep playing while it heals?

Usually yes, at reduced volume. A workable threshold is playing at a level that produces only mild symptoms which settle within 24 hours. If the elbow is worse the next morning, that session was too much. Complete cessation is rarely necessary and often counterproductive.

How do I know if it is tennis elbow or golfer’s elbow?

Tennis elbow hurts on the outside of the elbow and is aggravated by wrist extension - lifting a kettle, shaking hands, backhand. Golfer’s elbow hurts on the inside and is aggravated by wrist flexion and gripping. They can coexist, and the loading principles are similar with the direction reversed.

Should I get a cortisone injection?

Worth discussing with a doctor, with one key piece of information in hand: research consistently shows good short-term relief and worse outcomes at 6-12 months compared to exercise-based treatment. If you need to get through a specific event, that trade-off might be acceptable. As a first-line solution it generally is not.

Does a counterforce brace actually work?

Many people find it reduces symptoms during play by altering force transmission through the tendon. It manages symptoms rather than treating the cause, so it works best worn during play while a loading programme runs alongside it.

Why did it appear when my technique has not changed?

Because something else did - playing volume, string job, grip wear, a new gym programme, or a job change. Tendon symptoms lag the cause by days to weeks, so look back three to four weeks rather than at what you were doing when it first hurt.

How long until it is properly gone?

With consistent loading, expect meaningful improvement around 8-12 weeks and full resolution potentially longer, particularly if symptoms have been present for months. The most common reason a programme fails is stopping at week three.

TL;DR:

• Tennis elbow is a load problem in the wrist extensor tendons, not primarily a technique problem
• Check grip size first - too small forces harder squeezing, and overgrip build-up drifts it without you noticing
• Stiff polyester at high tension transmits far more shock; a multifilament and 4-6 pounds lower tension is a cheap experiment
• Sudden jumps in playing volume are the usual trigger, and symptoms lag the cause by weeks
• Progressive eccentric loading has the best evidence, and takes 8-12 weeks - not ten days
• Complete rest relieves symptoms without changing tendon capacity, so it recurs on return

Before you rebuild a backhand that was probably fine, measure your grip and look at what changed in your schedule a month ago.
