Pulled Hamstring? The Physio Guide to Getting Back Faster
Hamstring Strain: What Grade Is It and How Do You Get Back to Sport?
One second you are sprinting for the ball, the next you are hobbling off the pitch clutching the back of your leg. Hamstring strains are the single most common injury in running and kicking sports and the highest re injury rate of any sports injury. Here is exactly what grade you might have, what the honest recovery timeline looks like, and how our physio team at PHYZFIT Bexley North and Marrickville gets you back to sport.
Short Answer
Hamstring strains are graded 1 to 3 based on how many muscle fibres are torn. Grade 1 (mild) settles in 1 to 3 weeks. Grade 2 (moderate partial tear) takes 3 to 6 weeks. Grade 3 (complete tear or tendon avulsion) can take 3 to 6 months and may need surgical review. Physio led progressive loading, not stretching, is the gold standard rehab and dramatically reduces re injury risk, which sits at up to 30 percent within a year without proper rehab.
Below we walk you through the three grades, why hamstrings tear so often, what actually works in rehab, and when it is safe to return to sport.
What is the hamstring and why does it tear?
Your hamstrings are a group of three muscles on the back of your thigh: biceps femoris, semitendinosus and semimembranosus. They start at the sitting bone (ischial tuberosity) and cross both the hip and knee joints, which means they bend the knee, extend the hip, and slow the leg down as it swings forward when you run.
Because they cross two joints and take huge eccentric loads (lengthening while contracting) during sprinting, they are highly injury prone. Most hamstring strains happen in the late swing phase of sprinting, when the leg is decelerating just before the foot hits the ground.
Hamstring strains are the most common injury in AFL, soccer, rugby, sprinting and touch football. They also have the highest re injury rate of any sports injury, with roughly 1 in 3 hamstring strains recurring within 12 months if rehab is rushed or incomplete.
What grade is my hamstring strain?
Mild strain
A few muscle fibres torn or overstretched. Mild pain and tightness. Full strength and range mostly preserved. Often felt as "grabbing" or "pulling" during activity but you can usually keep playing.
Timeline: 1 to 3 weeks return to sport
Moderate partial tear
A larger portion of muscle fibres torn. Sharp pain at time of injury, often with a "popping" sensation. Noticeable weakness and range loss. Bruising often appears within 24 to 48 hours. Cannot continue playing.
Timeline: 3 to 6 weeks return to sport
Complete tear or avulsion
Complete rupture of a hamstring muscle, or a tear off the sitting bone (tendon avulsion). Severe pain, visible bruising, obvious weakness, sometimes a palpable gap. Unable to weight bear normally.
Timeline: 3 to 6 months, sometimes surgical review needed
Where in the muscle the tear happens also matters. Injuries near the muscle-tendon junction (mid muscle) recover faster than injuries close to the sitting bone (proximal), which are slower and more prone to recurring.
Why do hamstring strains keep coming back?
Because most people return to sport too early or without addressing the underlying reasons the muscle tore in the first place. The most common contributors:
- Poor eccentric hamstring strength. Sprinting requires massive eccentric loads. Weak hamstrings cannot control the deceleration and tear.
- Previous hamstring injury. The single biggest risk factor for a hamstring injury is a previous hamstring injury.
- Skipping the return to sprinting phase. A hamstring that has not been sprinted on has not been proven safe to sprint on.
- Fatigue. Most strains happen in the second half of games or towards the end of training when neuromuscular fatigue is highest.
- Age. Risk climbs from age 25 onward.
- Poor pelvic and lumbar control. Weak glutes and poor pelvic tilt control shift the load onto the hamstrings.
- Overstretching too early. Aggressive stretching in the first weeks after a strain can disrupt healing.

The evidence based hamstring rehab plan
Our physio team (Julian De Rosa, Ari Moushis and Sam Nunan) uses a staged loading protocol based on the best current evidence for hamstring rehab, including the Askling L-protocol and progressive eccentric loading. Julian is head physio for NPL football club Fraser Park FC and rehabs hamstring strains in soccer players every week.
Stage 1: Protection and pain settling (Days 1 to 5)
- Relative rest (offload but do not immobilise)
- Compression, ice for first 48 hours, elevation
- Gentle pain free walking
- Early isometric hamstring contractions in a shortened position
Stage 2: Progressive loading (Week 1 to 3)
- Isometric to isotonic hamstring loading
- Glute bridges and single leg glute bridges
- Slow eccentric hamstring lowers (Nordic curl progressions)
- Askling protocol lengthening exercises (extender, diver, glider)
- Pelvic control and core work
Stage 3: Running progression (Week 2 to 6)
- Start with jogging at 60 percent effort
- Build to 80 percent, then 90 percent, then full sprint
- Introduce change of direction work
- Sport specific drills (kicking, tackling, marking)
Stage 4: Return to play (Week 3 to 6 for grade 1, longer for grade 2)
- Full training completed pain free
- All return to sport criteria met (see below)
- Maintenance eccentric hamstring program continued for at least 12 weeks post return
Return to sport criteria — the checklist
Before we clear you to return to competitive play, we want to see all of these boxes ticked. Rushing back before this is done is the number one reason hamstrings tear again.
- No pain on hamstring provocation testing (askling H test)
- Full eccentric strength within 10 percent of the uninjured side
- Sprinting at 95 to 100 percent pain free
- Full change of direction work pain free
- Two full training sessions completed with no soreness afterward
- No apprehension or hesitation when accelerating or decelerating
- Sport specific drills (kicking, tackling, marking, jumping) completed pain free
What can I do at home right now?
- First 48 hours: compression (bandage or compression tights), ice for 15 minutes every 2 to 3 hours, elevate the leg when resting
- Walk within comfort. Do not fully immobilise or bed rest
- Avoid stretching in the first 5 to 7 days. Aggressive stretching disrupts early healing
- Early isometric contractions. Sitting on a chair, gently press your heel into the floor for 5 seconds. 10 reps, 3 times a day, as long as it is pain free
- Book a physio assessment early. The first 2 weeks set the recovery trajectory. Guessing the grade often means rehabbing at the wrong intensity
⚠ Seek urgent review if
- You heard or felt a pop and cannot weight bear at all
- There is significant bruising extending down to the calf or up into the buttock
- Pain at the sitting bone (ischial tuberosity) with a palpable gap (possible proximal avulsion needing surgical review, ideally within 2 to 4 weeks)
- Numbness, tingling or spreading leg pain (possible nerve involvement)
How long until I can play again?
- Grade 1: 1 to 3 weeks
- Grade 2: 3 to 6 weeks
- Grade 3: 3 to 6 months
- Proximal avulsion needing surgery: 6 to 9 months
These are averages. Older athletes, previous injury, poor early management and rushing back all extend timelines. Julian and our team have rehabbed dozens of Fraser Park FC hamstring injuries and we know how to balance getting you back fast with not sending you back too early.
We support athletes across Bexley, Kingsgrove, Beverly Hills, Bardwell Park, Earlwood, Rockdale, Kogarah and Hurstville from Bexley North, and Marrickville, Newtown, Enmore, Dulwich Hill and Petersham from Marrickville.
Frequently asked questions about hamstring strains
Not in the first 5 to 7 days. Early aggressive stretching disrupts the healing tissue and often prolongs recovery. Gentle lengthening exercises come in during Stage 2, but loading (strengthening) is what actually rebuilds the tissue.
Usually not for grade 1 or 2. MRI is considered if there is severe pain, inability to walk, suspected avulsion at the sitting bone, or when confirming grade for professional or high level athletes.
Yes. Multiple studies show a properly progressed Nordic hamstring program reduces hamstring injury risk by around 50 percent in team sport athletes. It is one of the highest evidence prevention exercises in all of sport.
Yes and you should. Single leg strength work on the uninjured side has a cross over effect and helps preserve strength on the injured side. Cardio (bike, swim, upper body ergo) also stays important.
Almost always because rehab stopped too early or never included a proper return to sprinting phase. A hamstring that has not been sprinted on has not been proven safe to sprint on.
Yes. Medicare covers 5 sessions per year under a Chronic Disease Management plan. Private health Extras rebates through HICAPS on the day. Workers Compensation, CTP and NDIS (plan managed and self managed only) are all accepted.
