The groin is one of those injuries that athletes often try to play through — and almost always regret. It starts as a twinge during a sharp change of direction, a stretch too far for a low drive, or a sudden sprint off the crease. You rest it for a few days, it feels okay, you go back too early, and suddenly what was a minor strain has become a persistent problem that dogs you for an entire season.

Adductor injuries are among the most common soft tissue injuries in field and court sports, and they're particularly prevalent in cricketers, footballers, and AFL players across the Inner West and Sydney more broadly. At SportsFit Health & Rehab — with clinics in Five Dock and Gladesville — we see a steady stream of groin injuries through the winter football season and the cricket summer alike.

This guide breaks down what's actually happening when you strain your groin, how to tell how serious it is, and what a proper rehab program looks like.

What is an adductor injury?

The adductors are a group of five muscles that run along the inside of your thigh, connecting your pelvis to your femur (thigh bone). Their primary job is to bring your legs together — adduction — but they're also heavily involved in controlling the pelvis during running, cutting, and kicking, and in absorbing load when you're changing direction or striding out.

When people say they've "done their groin," they've usually strained one or more of these muscles, most commonly at or near where the muscle attaches to the pubic bone. The key muscles involved:

Adductor longus

The most commonly injured adductor by a significant margin. Sits in the middle of the inner thigh and has a relatively narrow, high-tension attachment at the pubic bone — which is exactly where most acute tears occur. If someone's had a groin strain, there's a good chance this is the culprit.

Adductor brevis

Shorter and deeper than the longus, sitting underneath it. Less commonly injured in isolation but can be involved in more significant groin injuries. Harder to isolate clinically, which is why imaging can be useful for complex presentations.

Adductor magnus

The largest and most powerful of the group. Injuries here tend to happen further down the thigh toward the knee rather than at the groin. Less common than longus tears but can be more disabling when they do occur.

Gracilis and pectineus

The remaining two muscles of the group. Gracilis is long and thin, running all the way to the knee. Pectineus sits at the very top of the inner thigh near the hip. Both can be involved in groin injuries, particularly in complex or high-grade presentations.

It's also worth flagging that "groin pain" doesn't always mean adductor strain. The groin is anatomically complex — the hip joint, pubic symphysis, inguinal canal, iliopsoas, and hip flexors all share the same region. Conditions like hip labral tears, osteitis pubis, sports hernia (athletic pubalgia), and referred pain from the lumbar spine can all present similarly. Getting the diagnosis right from the start matters enormously for getting the right treatment.

Grading the injury

Like most muscle injuries, adductor strains are graded on a scale of one to three based on the extent of tissue damage. The grade shapes how aggressively you can load the muscle in early rehab and gives a rough guide to recovery timelines.

Grade 1 — Mild strain — minor fibre disruption

Localised tenderness at the adductor origin or along the muscle belly, mild discomfort with resisted adduction, but relatively preserved function. Many athletes can continue to train with modification. Return to full sport typically 1–3 weeks with appropriate management. The danger zone — athletes frequently under-manage these and tip them into grade 2.

Grade 2 — Partial tear — moderate fibre disruption

Clear pain at or near the pubic attachment, pain and weakness on resisted adduction, often with bruising tracking down the inner thigh over 24–48 hours. Walking may be uncomfortable; running and kicking are not possible. This is the most common presentation we manage at our Five Dock and Gladesville clinics. Return to full sport 4–8 weeks depending on severity and sport demands.

Grade 3 — Complete rupture — full-thickness tear

Fortunately uncommon for the adductors in isolation. Severe pain, significant swelling and bruising, and an inability to adduct against resistance without significant pain. A palpable gap may be present. Requires imaging to confirm and specialist assessment to discuss management — some complete proximal avulsions (at the bone attachment) may warrant surgical review. Recovery 3–6+ months.

A note on chronic groin pain: Not all adductor injuries present acutely. Osteitis pubis — a chronic inflammatory condition of the pubic symphysis — develops gradually in athletes with high rotational and adductor load demands (cricket, AFL, football). It presents as central or bilateral groin pain that's worse with activity and slow to respond to standard strain management. It requires a different treatment approach entirely, and we assess for it routinely in any groin presentation that doesn't respond as expected.

How does it happen?

Adductor injuries typically occur when the muscle is asked to generate high force while being stretched — an eccentric load. The tissue can't absorb the demand and fibres tear, usually at the proximal attachment near the pubic bone where the mechanical stress is highest.

Common mechanisms we see in our Inner West and Sydney patient population:

Rapid change of direction

Planting the foot and cutting hard to the opposite side places the adductors under sudden, high eccentric load. Common in football, AFL, and rugby — any sport that involves unpredictable lateral movement. The injury often happens when fatigue is a factor, late in a match or training session.

Kicking and striking

The follow-through phase of a kick or sweep shot requires the adductors to decelerate the swinging leg. In cricket, the low sweep and slog sweep are classic mechanisms — the leg abducts widely and the adductors have to control that range under load. In football, a mis-kicked ball or striking off balance creates similar risk.

Explosive acceleration from standing

Sprinting from a standing start — particularly between wickets in cricket, or from a set position in football — places high demand on the adductors as they contribute to initial push-off. The injury often occurs in the first few strides before the athlete is fully warmed into full-speed running.

Sliding or lunging movements

Fielding in cricket involves sudden full-stretch dives and lunges that take the hip into maximal abduction quickly. The adductors, caught in a lengthened position under load, can't always cope — particularly early in a long fielding session or on a cold morning at the oval.

Cumulative overload

Not all adductor injuries have a single "moment." High training loads, repeated bilateral kicking, or dense match schedules can gradually overload the adductor complex until an acute event tips it over the edge. The acute injury is often the culmination of weeks of subclinical load accumulation.

Risk factors worth knowing about: previous groin injury (the most powerful predictor of future injury), insufficient adductor strength relative to abductor strength, reduced hip range of motion, and a sharp spike in training load. We screen for all of these in athletes we work with through our Premier Grade cricket and AFL club partnerships.

Symptoms and what to look for

Groin strains have a fairly recognisable presentation, though the severity varies considerably.

At the time of injury:

• Sudden sharp pain in the groin or inner thigh — sometimes a "pop" or "snap" sensation

• Immediate cessation of activity in moderate to severe cases

• Pain reproduced by bringing the legs together against resistance (resisted adduction)

• In milder cases, a twinge or pull that the athlete initially tries to play through

In the hours and days after:

• Tenderness to touch at the pubic bone attachment or along the inner thigh

• Bruising tracking down the inner thigh (24–72 hours after injury)

• Pain walking, especially with wide steps or climbing stairs

• Stiffness and tightness in the groin, particularly first thing in the morning

• Pain with coughing or sneezing in higher-grade injuries (pubic bone involvement)

Signs that need urgent or specialist assessment:

• Significant swelling, bruising, or a palpable defect at the groin — possible complete rupture

• Groin pain with fever, testicular pain, or abdominal symptoms — rule out other causes

• Bilateral groin pain or pain at the pubic symphysis itself — assess for osteitis pubis

• Groin pain in a young athlete with hip stiffness and limited internal rotation — hip joint pathology must be excluded

• Pain that doesn't improve at all in the first 2–3 days with basic management

One thing that catches people out: groin injuries can mask or coexist with hip labral pathology, particularly in athletes with high rotational demands. If a groin strain isn't tracking the way it should through rehab, a deeper look at the hip is always on our assessment checklist.

How we assess it at SportsFit

The groin is one of the more complex regions to assess well — there are a lot of structures that can refer pain into the same area, and getting the diagnosis right determines everything that follows.

When you come into Five Dock or Gladesville, our initial assessment covers:

• Palpation of the adductor origin and muscle belly — identifying which muscle is involved and where the peak tenderness is located (at the pubic bone, the musculotendinous junction, or the belly). This guides both diagnosis and prognosis.

• Resisted adduction testing — in multiple positions (hip flexed, hip neutral) to differentiate adductor longus from other muscles, and to assess strength and pain response

• Hip range of motion — particularly internal and external rotation. Loss of hip IR is a red flag for intra-articular hip pathology that may be contributing

• Squeeze test — a validated test for adductor-related groin pain that gives us a reliable pain score to track through rehab

• Pubic symphysis assessment — direct palpation and stress testing to assess for osteitis pubis or pubic instability

• Load assessment — single leg squat, running patterns, and sport-specific movements to understand what the athlete can and can't do

For athletes with unclear presentations, significant injury, or a groin that hasn't responded to treatment elsewhere, we'll refer for diagnostic ultrasound. MRI is reserved for complex cases where pubic bone stress injury, labral pathology, or surgical decision-making is being considered.

We also take a thorough training load history. In our experience, most recurrent or slow-to-resolve groin injuries have a load management problem at the root of them — whether that's a schedule that's too dense, a return-to-sport that was rushed, or inadequate strength maintenance during a busy playing season.

Treatment: what proper adductor rehab looks like

Adductor injuries have a frustrating reputation for lingering — but in most cases, that reputation is earned through poor early management and premature return to sport rather than anything inherent about the injury itself. Done properly, even significant grade 2 tears can be rehabilitated efficiently.

Stage 1: Early management (days 0–5)

The first priority is settling the acute inflammatory response without going to the opposite extreme of complete immobilisation.

• Ice and compression in the first 48 hours

• Pain-free walking — complete bed rest is not indicated and can slow recovery

• Avoid aggressive stretching of the adductors in the first 48–72 hours — this is counterproductive during acute tissue healing

• Isometric adductor exercises (pressing the legs together against a pillow or ball) can begin very early — often within 24–48 hours — at pain-free load. Isometrics are one of the most effective tools we have for managing acute muscle pain and maintaining neuromuscular activation

• Activity modification rather than complete rest — upper body training, unaffected limb work, and pain-free cardiovascular alternatives

Stage 2: Progressive loading and strength (weeks 1–3)

Once the acute pain has settled and isometric work is pain-free, we introduce dynamic loading.

• Isotonic adductor exercises — side-lying adduction, Copenhagen adduction progressions (one of the best-evidenced adductor strengthening exercises available)

• Hip flexor and core integration work — because the adductors don't work in isolation; they work as part of a system involving the hip flexors, abdominals, and pelvic floor

• Bilateral lower limb loading — leg press, Romanian deadlift, split squat — that avoids direct adductor stress but maintains overall leg strength

• Manual therapy — soft tissue work to manage scar tissue, reduce local sensitivity, and restore tissue extensibility

• Pool running or low-impact cardiovascular work to maintain fitness

For cricketers — particularly bowlers and batters with heavy lower-body demands — we cross-reference treatment with our cricket physio approach to make sure the rehab is genuinely sport-specific and accounts for the unique demands of cricket movement patterns. The adductor load in a front-foot cover drive is very different to a lateral shuffle in football, and the program should reflect that.

Stage 3: Return to running and agility (weeks 3–6)

Before any return to running, we want to see:

• Pain-free resisted adduction at full effort

• Squeeze test score at or near zero

• Symmetrical adductor strength between sides

• Pain-free single leg squat

If those boxes are ticked, we build back into running via a structured walk-jog protocol, watching closely for any groin response. Straight-line running is introduced before lateral movement, which is introduced before full-speed cutting and kicking.

This is also where we address the hip mobility and pelvic control factors that may have contributed to the injury in the first place. Getting the athlete's adductor strength back is the floor — keeping them healthy long-term requires a more complete picture.

Stage 4: Sport-specific return to play

The final stage is the one most people rush and then regret. The demands of cricket, football, and AFL are high — explosive change of direction, maximal kicking, repeated sprinting over 80–120 minute sessions. The adductors need to be tested at those demands before the athlete is signed off.

For our cricket patients, this means progressive return to batting (starting with defensive straight drives before sweep shots and pulls), incremental bowling return for pace bowlers, and fielding-specific work including diving and sprinting from standing. For footballers and AFL players, full-speed cutting, contested marking, and game-intensity workloads are the benchmark.

We won't clear an athlete for full training just because they feel fine jogging. Feeling fine jogging and being genuinely ready for sport are very different things.

Recovery timelines: what to realistically expect

• Grade 1 — Return to light activity: 2–5 days; Return to full sport: 1–3 weeks

• Grade 2 — Return to light activity: 1–2 weeks; Return to full sport: 4–8 weeks

• Grade 3 — Return to light activity: 3–6 weeks; Return to full sport: 3–6+ months

Adductor injuries that involve the proximal tendon (near the pubic bone attachment) rather than the muscle belly itself tend to take longer — the tendon has a poorer blood supply and is slower to remodel. Presentations with osteitis pubis as a comorbidity add further complexity and are typically managed over a 3–6 month horizon even in relatively mild cases.

Recurrence is the biggest risk. An adductor that's been strained once has scar tissue that's stiffer and less mechanically compliant than the original muscle. This makes it more susceptible to re-injury if the return-to-sport criteria aren't genuinely met before going back.

Preventing the next groin strain

The evidence on adductor injury prevention is actually quite strong, which is unusual in sports medicine. Here's what works:

• Copenhagen adduction exercises. The most well-researched intervention for adductor injury prevention. Running a structured Copenhagen program through your pre-season and in-season can dramatically reduce groin injury risk. They're hard — that's why athletes avoid them — but the evidence behind them is solid.

• Maintain adductor-to-abductor strength ratio. Ideally you want your adductor strength at roughly 80% or above of your abductor strength. Athletes with significant imbalance are at higher risk.

• Warm-up properly before lateral and explosive work. A cold adductor asked to decelerate a maximal kick is an injury waiting to happen. Dynamic warm-up that includes lateral movement and progressive adductor loading matters — especially for early morning oval sessions in winter.

• Manage training load intelligently. Most groin injuries happen during load spikes — pre-season ramp, returning from holidays, or squeezing too many training sessions into a short block. Build gradually.

• Don't ignore the grade 1s. This is the most actionable thing on this list. Every persistent, chronic groin problem we see started as a minor twinge that was played through without adequate rest and rehabilitation. Address it early.
