Padel Overgrip and Arm Health: The Injury Prevention Nobody Talks About
Worn overgrip causes compensatory gripping that accumulates into lateral epicondylitis. It takes 3 minutes to fix. Here's the complete guide.
21%more forearm activation from under-sized grip
By Ilhaam Buckas, Founder, Smash.Overgrip replacement is padel's most cost-effective injury prevention measure: research shows that an undersized grip increases forearm muscle activation by up to 21%, directly contributing to lateral epicondylitis (tennis elbow). Replacing an overgrip every 6–8 hours of play costs under $1 and maintains optimal cushioning — yet most recreational players replace theirs less than twice a year.
What you'll learn
- Under-sized grips increase forearm muscle activation by up to 21% — measured, not estimated
- Worn overgrip becomes slick, forcing a compensatory death-grip that accumulates directly into lateral epicondylitis
- Factory grips are too thin for most players — add 1–2 overgrips from new
- Replace overgrip every 3–5 hours of play — not monthly, not when it looks bad, every 3–5 hours

How Grip Condition Causes Arm Injury
The mechanism is straightforward but underappreciated. When a grip surface becomes slick — through wear, sweat absorption, or flattening of the grip texture — the hand cannot maintain a secure hold without actively squeezing the handle. This is not a conscious decision; it is an automatic, reflexive response to the sensation of the racket potentially slipping.
Squeeze force in the hand activates the forearm flexors and extensors simultaneously — the muscles that attach at the lateral epicondyle. At normal grip friction, the hand uses only the force required for the shot. At reduced grip friction, the hand maintains baseline squeeze throughout the rally, adding continuous low-grade load to the forearm on top of the impact load from each shot. Over a 90-minute session, this accumulates. Over weeks of sessions on a worn grip, it produces chronic inflammation at the lateral epicondyle.
Research measuring forearm muscle activation with undersized versus correctly sized grips has found up to 21% greater activation in the forearm extensors with undersized handles. This is not marginal — it represents a significant increase in tissue load from a variable that costs less than £2 and 3 minutes to fix.
Why Factory Grips Fail Most Players
Your factory grip is probably wrong
Padel rackets ship with a factory grip that is sized for a 'standard' hand — a specification that represents a compromise across a wide range of hand sizes, and that errs on the thin side for two reasons: thin grips are cheaper to produce, and players with smaller hands cannot add material to a grip that is already too thick, but players with larger hands can easily add overgrips.
The result is that a majority of adult male padel players receive a racket with a grip that is too thin for their hand, and a significant proportion of adult female players are also affected. Playing on a too-thin grip from the first session means loading the forearm more than necessary from the beginning.
The fix is simple: add 1–2 overgrips over the factory grip from day one. This adds 0.5–1mm of diameter per overgrip and introduces fresh, high-friction surface texture. The cost is negligible, the installation takes 3 minutes, and the difference in forearm load is immediate. Many players report that arm discomfort they had attributed to overtraining resolves within weeks of correcting their grip size.
How to Find Your Correct Grip Size
The thumb-finger gap method
The most reliable field method for assessing grip size is the thumb-finger gap test. Grip the racket in your normal forehand position. Look at the gap between the tips of your fingers and the base of your thumb.
If your fingertips are digging into your palm with no visible gap, the grip is too thin — add at least one overgrip.
If you can see a gap of approximately 5–8mm between fingertips and the base of the thumb, the size is approximately correct.
If the gap is wider than 10mm, the grip may be too thick — though this is far less common than the reverse.
For players who are unsure, starting with two overgrips over the factory grip and assessing the thumb-finger gap is a practical approach. Remove one overgrip if the gap becomes too wide. The correct size should feel secure without requiring active squeeze — the grip should feel like it stays in your hand without effort.
Choosing the Right Overgrip
Padel overgrips split into three categories: dry, tacky, and absorbent. Each has a different feel and suited application.
Dry overgrips have a slightly rough, high-friction texture that provides consistent grip in both dry and light-sweat conditions. They are the most common choice for players who sweat moderately and want consistent control. Wilson Pro Overgrip and Babolat VS Tour are typical examples.
Tacky overgrips have a sticky surface that provides very secure grip but degrades faster as the tackiness picks up surface contamination. They suit players who prefer a grip that almost adheres to the hand and who are willing to replace grips frequently.
Absorbent overgrips are designed for high-sweat players — they manage moisture actively, staying grippy longer in humid conditions. If your primary problem is slipping in hot or humid conditions, absorbent overgrip is the right solution.
For most players in temperate climates, a standard dry overgrip replaced frequently is the most reliable choice. The brand matters less than the replacement frequency — a fresh Wilson Pro Overgrip outperforms a month-old Babolat VS Tour every time.
Replacement Frequency: The Single Most Important Habit
This is the part of overgrip maintenance that almost no player does correctly. Most recreational players replace their overgrip when it looks visibly bad — grey, shredded, slippery. By that point, the grip has been functionally worn out for weeks and the forearm has been paying the price.
The correct replacement interval is every 3–5 hours of active play. This sounds frequent — and at first, the grip will look fine when you change it. That is the point. You are replacing it before the friction drops to the level that triggers compensatory gripping, not after.
For a player who plays three sessions of 90 minutes per week, 3–5 hours of play means changing the overgrip every 1–2 sessions. At a cost of approximately £1–2 per overgrip, this is one of the cheapest injury prevention interventions available in any sport.
Buying overgrips in bulk (10-packs are standard and cost £8–15) removes the friction of the replacement habit — having grips available means you do not defer the change because you need to go to the shop first. Keep a packet in your kit bag and change at the start of every other session as a default habit.
Key terms defined
- Lateral epicondylitis
- Padel's most common overuse injury, also called tennis elbow; caused by repeated forearm muscle loading from grip tension, improper technique, or equipment mismatch.
- Overgrip
- A thin cotton or polyurethane wrap applied over the stock grip to increase diameter, cushioning, and sweat absorption; replacement is the first step when arm discomfort appears.
- Grip diameter
- The circumference of the racket handle; correct sizing keeps the ring finger just touching the palm — too narrow forces a compensatory grip that strains the forearm.
- Death grip
- Unconscious over-tightening of the grip when the handle feels slick or undersized; the primary biomechanical cause of overuse arm injuries in padel.
Our Verdict
Overgrip Verdict
Replace your overgrip every 3–5 hours of play. Add 1–2 overgrips from factory. Check the thumb-finger gap at your current grip size and add layers until the gap is 5–8mm. A worn, flat overgrip is a direct and preventable cause of lateral epicondylitis in padel players — and it costs £2 and 3 minutes to fix. If your elbow hurts, check your grip before anything else.
Change overgrip every 3–5 hours of play. Start with 1–2 overgrips over factory grip. Use the thumb-finger gap method to confirm sizing.Get SmashIQ to analyse your racket technique

How often should I replace my padel overgrip?
Every 3–5 hours of play. This is more frequent than most players manage, but it is the interval at which friction drops enough to trigger compensatory gripping. At £1–2 per overgrip, buying in bulk and changing every 1–2 sessions is one of the cheapest injury prevention habits in padel.
Does grip size really affect tennis elbow?
Yes — research shows undersized grips increase forearm extensor activation by up to 21%. Over a season of play, this accumulated extra load is a direct contributor to lateral epicondylitis. Correcting grip size is often the first intervention that produces meaningful relief.
How many overgrips should I add to the factory grip?
Usually 1–2. Factory grips are sized on the thin side for manufacturing and logistics reasons. Start by adding 2 overgrips and use the thumb-finger gap method to check: you want a 5–8mm gap between fingertip and the base of the thumb in your normal forehand grip.
What type of overgrip is best for padel?
For most players in temperate climates, a standard dry overgrip (Wilson Pro Overgrip, Babolat VS Tour, or equivalent) replaced frequently is the best choice. High-sweat players benefit from absorbent overgrip. The brand matters less than replacement frequency.
