Padel Groin Strain
Adductor muscle injuries from lateral split-steps, wide lunges, and rapid direction changes. Grades 1-3, acute care, 3-phase rehab, and Copenhagen plank prevention.
Fewer groin injuries with a Copenhagen plank protocol (Danish study)
Grade 2 recovery — the most common padel presentation
Adductor longus — the most frequently strained adductor in sport
In short: a padel groin strain is an adductor muscle injury caused by the sport’s extreme lateral demands. Grade 1 heals in 1-2 weeks. Grade 2 takes 4-6 weeks. Grade 3 needs a surgical assessment. The Copenhagen plank is the single best evidence-based exercise to prevent it from happening again.
The Adductor Muscles: What Gets Strained and Why
Five muscles work together to pull your leg inward. In padel, all five are under extreme eccentric load.
The Five Adductor Muscles
The most commonly strained adductor. Originates at the pubic crest and symphysis, runs obliquely down to the medial femur. It is the first to load during a wide split-step and the first to give way under excessive stretch.
The largest and deepest adductor. Bridges the inner thigh from the pubic ramus to the medial epicondyle of the femur. Less commonly torn in isolation, but central to explosive push-off strength.
The shortest adductor. Sits between longus and magnus and primarily assists hip flexion alongside adduction. Rarely strained alone but is frequently irritated when longus is injured.
A long, thin muscle running from the pubis to just below the medial knee. It also flexes the knee, meaning a gracilis strain can cause inner knee pain that mimics ligament injury.
The most anterior adductor. Assists both hip adduction and flexion. Pectineus strains often present as deep groin pain felt more at the front of the hip crease than the inner thigh.
Why Padel Specifically Causes Groin Strains
Three movement patterns concentrate enormous force through the adductors
1. The Lateral Split-Step
The split-step lands with both feet wide. In that moment of landing, the adductors are working eccentrically — contracting while being stretched — to absorb impact and control the stance. If the foot plants wider than expected, or if the push-off is explosive without adequate preparation, that eccentric demand spikes beyond what the muscle can handle. This is the single most common mechanism for adductor longus strain in padel.
2. Rapid Direction Changes
Changing direction in padel happens within one to two steps. The trailing leg must absorb the deceleration force while the leading leg drives the new direction. Both actions load the adductors simultaneously. In a three-hour match with hundreds of direction changes, cumulative fatigue is the hidden injury trigger — the muscle does not fail at peak freshness, it fails after the 400th sprint of the evening.
3. Wide Defensive Lunges
Reaching for a ball at the wall or in the back corner demands a lunge well outside the normal base of support. In that wide position, the adductors are stretched toward end-range. Add the rotational force of a forehand or backhand at the same moment and you have the perfect storm for a muscle tear. This pattern is especially common when players are fatigued late in a match.
Groin Strain Grades 1, 2 and 3
The grade tells you how much tissue is damaged and how long you will be off the court
| Grade | Tissue Damage | Symptoms | Recovery |
|---|---|---|---|
| Grade 1 | Mild — less than 5% of fibres torn | Mild tightness in the groin. You can walk normally. Tender on palpation. No visible bruising. | 1-2 weeks |
| Grade 2 | Partial tear — 5-95% of fibres disrupted | Antalgic gait (limping). Weak adduction against resistance. Possible bruising along the inner thigh after 24-48 hours. | 4-6 weeks |
| Grade 3 | Complete rupture — full thickness tear | Severe acute pain. Unable to adduct against any resistance. Significant bruising tracking toward the knee. Requires surgical assessment. | 3-6 months (surgical or conservative) |
Hip flexor strain: Pain on resisted hip flexion (lifting the knee), not adduction. The hip flexor (iliopsoas) sits anterior to the adductors. Test: squeeze your knees together against resistance — if it hurts, that is adductor. Lift your knee against resistance — if that hurts more, that is hip flexor.
Sports hernia / Athletic pubalgia: Pubic symphysis pain that worsens with exertion, coughing, or sneezing. No acute onset mechanism. Pain is felt at the midline rather than the inner thigh. Requires imaging and specialist referral — physiotherapy alone is insufficient.
Acute Treatment: The First 72 Hours
What you do in the first three days determines how fast the next six weeks go
Hours 0-72: Immediate Management
Continuing to play on a grade 2 or 3 strain risks converting a partial tear into a complete rupture. No match is worth six months off court.
Wrap ice in a cloth — never direct skin contact. Ice reduces acute bleeding into the tissue and controls pain. Continue for the first 48-72 hours.
A compression bandage or compression shorts reduce swelling. Relative rest means no lateral movement, sprinting, or kicking. Walking flat on level ground is fine for grade 1 and most grade 2 strains.
Gentle isometric holds begin the healing signal without stressing the tear. Sit with knees bent, place a ball or folded towel between your knees, and squeeze gently for 5 seconds. If pain-free, this is your first rehabilitation exercise.
If you cannot walk without limping 24 hours after injury, or if bruising tracks down the inner thigh, see a physiotherapist or sports doctor within 48 hours. Ultrasound can confirm grade and rule out avulsion fracture.
3-Phase Rehabilitation Plan
Isometric to isotonic to sport-specific — the progression that protects against re-injury
Goal: Reduce pain, control swelling, begin the healing signal through gentle isometric muscle activation.
Isometric adduction squeeze: Seated, knees bent to 90 degrees, ball or towel between knees. Squeeze for 5 seconds, relax. 3 x 10 reps, 2-3 times daily. Pain must stay below 3/10.
Standing isometric holds: Stand beside a wall. Press the inside of the injured leg against the wall with gentle force. Hold 5-10 seconds. If pain-free, progress ramp of force over days 3-5.
Avoid: Stretching the groin (counter-intuitive but correct — early passive stretching disrupts healing fibre alignment). No running, cutting, or wide stance movements.
Goal: Restore full range of motion, rebuild adductor strength through concentric and eccentric loading.
Side-lying hip adduction: Lying on the uninvured side, lower leg straight. Lift the lower leg off the floor through adduction. 3 x 15 reps. Add ankle weight progressively (0.5 kg increments).
Standing cable or band adduction: Attach resistance band at ankle height. Stand side-on. Pull the injured leg across midline against resistance. Slow eccentric return over 3-4 seconds. 3 x 12 reps.
Sumo squats: Wide stance, toes turned out 30-45 degrees. Controlled descent. Adductors work eccentrically on the way down. Begin bodyweight, add load when pain-free through full range.
Copenhagen plank progressions (short lever): Place the lower leg on a bench with the ankle supported. Body in side-plank position. Hold for 10-20 seconds. Builds adductor endurance in a loaded lateral position.
Goal: Replicate the exact movement patterns of padel at progressive intensity. Do not return to match play until all criteria are met.
Lateral shuffle drills: Low-intensity lateral shuffles at half-court width. Progress to full width over 2-3 sessions. Introduce change of direction once lateral running is pain-free.
Split-step practice: Practice the padel split-step pattern on court without hitting. Focus on landing width and controlled deceleration. Start narrow, progress to match-width over one week.
Copenhagen plank (long lever): Ankle on bench, full body side-plank. Hold 20-40 seconds. This is the benchmark exercise for return-to-sport adductor readiness.
Progressive on-court rallies: Feeding-only sessions first, then cooperative rallies, then competitive points. Match play last.
You know the feeling — a tweak in the groin, a moment of doubt mid-rally, and then the choice: do you keep playing or stop? Most players don’t realise that pushing through a grade 2 strain can double the recovery time. What actually works is stopping immediately, starting pain-free isometrics within 24 hours, and following the phase progression without shortcuts.
Prevention: Adductor Strengthening and Copenhagen Planks
The strongest evidence base in sports medicine for groin injury prevention
The Copenhagen Plank: How to Do It Correctly
- Lie on your side. Place the lower knee on a bench at knee height.
- Forearm on floor directly under shoulder. Body in side-plank.
- Lift hips so the body forms a straight diagonal line.
- Hold 10-20 seconds. Lower with control.
- 3 sets each side. 2 minutes rest between sets.
- Lie on your side. Place the lower ankle (not knee) on a bench.
- Same side-plank position as above.
- Greater leverage means higher adductor force.
- Target: 3 x 30 seconds each side before return to play.
- For prevention: 2 x 20 seconds each side, 2-3 times per week.
The Weekly Prevention Protocol
Add these to your pre-match or gym routine. Three sessions per week is the dose used in the Danish research.

Frequently Asked Questions
How do I know if my groin strain is grade 1, 2 or 3?
Grade 1: mild tightness, you can walk normally, tender when pressed. Grade 2: partial tear, you limp, weak adduction against resistance, bruising may appear after 24-48 hours. Grade 3: severe acute pain, you cannot adduct at all, significant bruising. If you are not sure, see a physiotherapist — ultrasound confirms the grade and rules out avulsion fracture at the pubic attachment.
Can I keep playing padel with a groin strain?
Not with a grade 2 or 3. Playing through a partial tear risks converting it into a complete rupture, turning a 4-6 week injury into a 3-6 month one. A mild grade 1 may tolerate carefully modified play, but lateral movement and explosive split-steps should be avoided until pain resolves.
How long does a padel groin strain take to heal?
Grade 1 strains heal in 1-2 weeks with good management. Grade 2 strains typically take 4-6 weeks. Grade 3 ruptures can take 3-6 months and may require surgical assessment. These timelines assume you follow a proper rehabilitation protocol — returning too early based on pain resolution alone significantly increases re-injury risk.
What is the Copenhagen plank and why is it used for groin injury prevention?
The Copenhagen plank is a side-plank variation where the lower leg rests on a bench, forcing the adductors to work isometrically against the lever of the full body weight. A Danish study demonstrated a 31% reduction in groin injuries among elite athletes who completed a Copenhagen plank protocol versus controls. It directly trains adductor strength in the same loaded lateral position the muscles must handle during a padel split-step.
Is it safe to stretch the groin after a strain?
Not in the first 3-5 days. Early passive stretching of a strained muscle disrupts the healing fibre alignment and slows recovery. Pain-free isometric exercises (squeezing, not stretching) are the correct early intervention. Gentle range-of-motion work can begin once acute pain has settled, typically from day 5-7 for grade 1 and week 2-3 for grade 2.
How is a groin strain different from a sports hernia?
A groin strain has an acute onset mechanism (a wide movement, a sudden pull) and produces inner thigh pain that is worse with hip adduction against resistance. A sports hernia (athletic pubalgia) involves pubic symphysis or inguinal pain that builds gradually with exertion and is reproduced by coughing, sneezing, or sit-ups. Sports hernia rarely has an acute onset and does not respond to standard adductor rehabilitation alone. If your pain is at the midline and there was no acute incident, seek specialist assessment.
When can I return to padel after a groin strain?
Return to play when: you are pain-free during all lateral movements including explosive split-steps; adduction strength equals the uninvolved side on manual testing; you can complete 3 x 30 seconds of the Copenhagen plank (long lever) without discomfort; you have completed sport-specific drills at full intensity without symptoms. Do not base return on a calendar. Base it on meeting these criteria.
