Hamstring Strains: Why Seeing a Sports Doctor Early Matters

July 2026

By Essendon Sports Medicine Team

If you've ever watched an AFL player suddenly pull up during a sprint and grab the back of their thigh, you've seen one of sport's most frustrating injuries in action.

One moment they're chasing down an opponent. The next, they're limping from the ground, their game over before it really began.

It's a scene that repeats itself every football season—and not just in the AFL. Across local football, soccer, athletics, rugby and weekend sport, hamstring strains are among the most common injuries we see. During the business end of the footy season, when training intensity increases and fatigue begins to accumulate, hamstring injuries become even more frequent.

Unfortunately, many people assume it's "just a pulled hamstring" and try to manage it themselves. A few days of rest, some stretching and a gradual return to running might seem like enough. But this approach often leads to a recurring cycle of reinjury.

The reality is that not all hamstring strains are the same. The location, severity and cause of the injury all influence recovery time and your risk of doing it again.

That's why seeing a sports doctor early is one of the smartest decisions you can make. An accurate diagnosis allows you to receive the right treatment from the beginning, helping you return to work, training and competition as safely—and as quickly—as possible.

What You’ll Learn in This Blog:

• Why hamstring strains are so common in AFL, soccer and other running sports—and why getting the right diagnosis early matters.
• How sports doctors assess hamstring injuries, when imaging may be needed, and what treatment options can help you recover safely.
• What evidence-based rehabilitation and return-to-sport strategies can reduce your risk of reinjury and get you back to performing at your best.

What is a hamstring strain?

The hamstrings are a group of three muscles located at the back of the thigh:

• Biceps femoris

• Semitendinosus

• Semimembranosus

Together, they bend the knee, extend the hip and play a critical role during running, sprinting, jumping and kicking.

A hamstring strain occurs when one or more of these muscles—or their tendons—is overloaded beyond its capacity, resulting in microscopic or larger tears within the tissue.

Most injuries occur during:

• Sprinting at high speed

• Accelerating

• Decelerating

• Sudden changes of direction

• Kicking

• Lunging or overstretching

These movements place enormous force through the hamstrings, particularly when they are lengthening while trying to slow the leg down.

Why are hamstring strains so common in AFL and soccer?

Few sports demand more from the hamstrings than Australian Rules Football and soccer.

Players repeatedly perform explosive accelerations, maximal sprinting, kicking, tackling and rapid changes of direction throughout a match. Fatigue later in games further increases the load on the muscles.

In elite AFL, hamstring strains consistently rank among the most common injuries and remain one of the leading causes of missed matches each season.

Importantly, they're not just an elite athlete problem.

Weekend footballers, masters athletes, runners and anyone returning to exercise after time away are all susceptible.

What does a hamstring strain feel like?

Symptoms vary depending on the severity of the injury, but commonly include:

• Sudden pain in the back of the thigh

• A sharp "grab" or tearing sensation

• Difficulty continuing to run

• Pain when walking

• Tenderness over the injured area

• Swelling or bruising over the following days

• Weakness when bending the knee

• Pain during sprinting or kicking

Some people can continue playing after a mild strain, while others are unable to bear weight immediately.

The severity of symptoms doesn't always reflect the seriousness of the injury, which is why assessment is important.

Not all hamstring injuries are equal

One of the biggest misconceptions is that every hamstring strain heals in the same way.

Sports doctors assess several important factors, including:

• Which hamstring muscle is involved

• Whether the muscle or tendon is injured

• The location of the tear

• The size of the injury

• Whether surrounding structures are involved

• Your sporting goals and training demands

These details significantly influence recovery and the likelihood of recurrence.

Grade 1

A small number of muscle fibres are injured.

Typical features include:

• Mild pain

• Minimal strength loss

• Little or no bruising

• Walking usually remains possible

Recovery often takes several weeks with appropriate management.

Grade 2

A moderate tear involving more muscle fibres.

Symptoms often include:

• Noticeable pain

• Reduced strength

• Difficulty running

• Bruising and swelling

These injuries generally require a structured rehabilitation program before returning to sport.

Grade 3

A complete rupture of the muscle or tendon.

This may involve:

• Sudden severe pain

• Significant weakness

• Extensive bruising

• Difficulty walking

Some complete tears, particularly tendon avulsions, may require surgical assessment.

Why seeing a sports doctor early matters

One of the biggest mistakes athletes make is waiting several weeks before seeking assessment.

Early review by a sports doctor can make a significant difference to both recovery and return-to-play decisions.

A sports doctor can:

• Confirm the diagnosis

• Exclude more serious injuries

• Assess injury severity

• Determine whether imaging is needed

• Identify factors that contributed to the injury

• Develop an evidence-based treatment plan

• Coordinate rehabilitation with your physiotherapist and other healthcare providers

• Guide a safe return to training and competition

Rather than guessing when it's safe to play again, you'll have a clear plan based on your individual injury.

Do you need an MRI?

Not always.

Many hamstring strains can be accurately diagnosed through a detailed history and physical examination.

However, imaging may be recommended if:

• The diagnosis is unclear

• A more significant tear is suspected

• Symptoms are unusually severe

• There is concern for tendon involvement

• Surgical management may be required

• Recovery is not progressing as expected

When appropriate, your sports doctor can organise imaging and interpret the findings in the context of your symptoms and sporting goals.

It's important to remember that MRI findings don't automatically determine when you're ready to return to sport. Clinical assessment, strength, function and confidence are equally important.

Why do hamstring strains keep coming back?

Hamstring injuries have one of the highest recurrence rates in sport.

Research has shown that reinjury commonly occurs within the first few weeks after returning to competition.

This usually isn't because the original injury "didn't heal." More often, athletes return before they have fully restored:

• Strength

• Sprint capacity

• High-speed running tolerance

• Muscle endurance

• Power

• Confidence

Simply being pain-free isn't enough.

Returning too early dramatically increases the likelihood of another strain.

What does treatment involve?

Treatment depends on the severity of the injury, your sport and your goals.

Management commonly includes:

Early management

Initially, treatment focuses on:

• Protecting the injured tissue

• Managing pain

• Maintaining gentle movement

• Avoiding unnecessary loss of strength

Complete rest is rarely the best solution.

Instead, carefully progressing activity under medical guidance helps support recovery.

Rehabilitation

Once the diagnosis has been established, physiotherapy becomes an essential part of recovery.

A structured rehabilitation program typically includes:

• Progressive strengthening

• Hamstring loading

• Hip and pelvic control exercises

• Core strengthening

• Running progression

• Sprint retraining

• Sport-specific drills

• Return-to-play testing

Rehabilitation isn't simply about eliminating pain—it's about restoring the ability to tolerate the demands of your sport.

Return to sport

One of the most valuable roles of a sports doctor is helping determine when it's genuinely safe to return.

This decision considers:

• Strength testing

• Functional performance

• Sprint exposure

• Ongoing symptoms

• Confidence

• Sport-specific demands

• Risk of recurrence

Returning a week too early can sometimes mean missing another two months.

Can hamstring strains be prevented?

While no injury can be completely prevented, many hamstring strains are avoidable.

Effective prevention strategies include:

Build hamstring strength

Strong hamstrings tolerate higher running loads.

Progressive strengthening—including eccentric exercises where appropriate—has been shown to reduce injury risk.

Prepare for sprinting

Many injuries occur because athletes haven't regularly exposed themselves to high-speed running during training.

A gradual increase in sprinting volume helps prepare the muscles for match conditions.

Manage training loads

Sudden spikes in running volume or intensity increase injury risk.

A consistent, progressive training program is generally safer than alternating between inactivity and very hard sessions.

Address previous injuries

A previous hamstring strain remains one of the strongest predictors of another injury.

A sports doctor can help identify ongoing deficits that may not be obvious during everyday activity.

Don't ignore fatigue

Late-season football places enormous demands on the body.

Adequate recovery, sleep, nutrition and sensible training loads all contribute to injury prevention.

When should you see a sports doctor?

You should arrange an assessment if you experience:

• A sudden sharp pain while sprinting or kicking

• Difficulty walking after the injury

• Significant bruising or swelling

• Recurrent hamstring injuries

• Pain that isn't improving after several days

• Ongoing pain when running

• Difficulty returning to training

• Concerns about when it's safe to play again

The earlier the assessment, the sooner an accurate diagnosis and management plan can be established.

The bottom line

Hamstring strains are one of the most common injuries in AFL, soccer and many other running sports. While they may seem straightforward, they vary considerably in severity and are well known for recurring if they're not managed appropriately.

Early assessment by a sports doctor helps identify exactly what has been injured, determine whether imaging is needed and develop a personalised treatment plan. From there, a structured rehabilitation program—including physiotherapy where appropriate—can progressively restore strength, speed and confidence before returning to competition.

If you've strained your hamstring, don't rely on guesswork or wait until it becomes a recurring problem. Getting assessed early gives you the best chance of recovering well and reducing your risk of missing more of the season than necessary.
