Hamstring Tear (or Strain): What You Don't Know About It

-

Introduction

Imagine you are watching your favourite athlete–maybe Usain Bolt–sprinting towards the finish line in a 4 x 100m relay. Suddenly he slows down, starts limping on his left leg, and pain clouds his face. Despite his determination, he can't push through and has to stop. 


But this wasn’t just a dramatic scene from your imagination…


It was a real moment from 2016. A heartbreaking one for Bolt, his team, and fans around the world—caused by a hamstring tear. Surprisingly, this isn’t just a “professional athlete” problem. It’s one of the most common injuries among athletes and active individuals alike. Surprised? Let’s dive into what a hamstring tear really is—and why it might be more common than you think.


Understanding the basics of a hamstring

What happens when something tears? It means it’s been overstretched or pushed beyond its limit—like when you pull a rubber band too far and it snaps. Now, unlike a rubber band that can’t heal itself, the good news is: your hamstrings can.


So, what exactly is a hamstring—and where can you find it?

Simple. Locate your thigh (your lap), then place your hand at the back of your thigh. That region is home to your hamstrings: a group of three muscles working together.


What do these muscles actually do?

Time to get a bit science-y. Your thighs are made up of two main muscle groups:

  • The quadriceps (4 muscles) at the front, and

  • The hamstrings (3 muscles) at the back.

These two groups are kind of like opposites—they balance each other out. If your quads help you extend your knee and run forward, your hamstrings help you bend your knee and stabilize movement.

Let’s make this practical.

  • Try a squat right now—seriously, give it a shot.

  • When you lower your body, your quads are doing the heavy lifting.

  • When you rise back up, your hamstrings are firing to bring you upright.

Now try placing your hands on your thighs while doing the squat—you’ll actually feel those muscles at work. Cool, right?


What happens during a Hamstring Tear? 

Can you recall a moment when you took a sudden, wide stride—maybe while running or trying to catch a bus—and suddenly felt a sharp pain at the back of your thigh? That sharp jolt could mean your hamstrings were stretched beyond their limit and tore. Essentially, there’s a small (or sometimes large) cut in the muscle fibers. Once this happens, the leg can no longer move as efficiently. Running becomes difficult—if not impossible—because the muscle has lost its natural recoil. That snap you felt? That’s the tear. It stops you mid-motion. That’s exactly what happened to Usain Bolt.


Hamstring tears are classified into three grades based on severity:

  • Grade 1: Mild strain—some tightness, but you can still walk.

  • Grade 2: Partial tear—pain, swelling, bruising, and difficulty moving.

  • Grade 3: Complete tear—severe pain, swelling, and inability to use the leg properly.


Why Does It Happen?

There are several reasons why a hamstring tear might occur:

  • Skipping warm-ups: Cold muscles tear easier.

  • Muscle imbalance: Strong quadriceps overpowering weak hamstrings.

  • Fatigue or past injury: Tired or previously injured muscles are more vulnerable.

  • Sudden explosive moves: Sprinting, jumping, quick turns.

  • Tightness & poor mobility: Less flexibility = higher risk.


What to Do When (or If) It Happens

As we mentioned earlier, this can happen to anyone—not just athletes. So, it’s important to know what to do if it happens to you or someone around you. First step? Stop, rest, and apply ice. Don’t push through the pain.


We’re dropping a full DIY recovery guide this Thursday—step-by-step tips to manage and recover from a tear. Stay tuned!


Final Note

Understanding your body—how it moves, and why injuries like a hamstring tear occur—gives you power. Whether you’re sprinting like Bolt or simply going about your daily activities, a little awareness goes a long way. In our upcoming DIY guide, we’ll show you how to bounce back safely—and maybe even stronger.

Truth be told, there has been an ongoing debate for centuries—which is better for pain and injury recovery: cold therapy or hot therapy? And today, it’s time to demystify it once and for all! Although we began last week with " The Arthritis and Its Physiotherapist "—and yes, we’ll continue exploring that topic—understanding this battle and knowing who the real winner is will help you manage your body better. So, sit back, relax, and let’s finally uncover the truth! Let’s Get Creative for a Moment… Take a nostalgic walk back to childhood. Who remembers those moments when, as kids, we fell, hit our heads, or bumped our knees—only to end up with a swollen lump on our foreheads? (Take a smile if you were one of the ‘forehead bumpers’!) What happened next? Your mother or guardian rushed in, cradled you in their lap, and out came that small, red-labeled hot balm bottle—whether it was Robb, Aboliki, or another strong-smelling ointment. Or she could even dab that place with something...

Exercise is supposed to be the ultimate stress reliever, right? The thing that makes you feel invincible, like you can take on the world. For fitness enthusiasts, it’s pure joy—a dose of happy hormones and the thrill of progress. But for the rest of us mere mortals? Exercise can sometimes leave us feeling like we’ve been hit by a truck. Why? Because you wake up the next day and—surprise!—you’re sore all over. Your arms feel like noodles, your legs are protesting every movement, and even lifting your morning coffee feels like a workout. Sound familiar? Welcome to the not-so-glamorous world of Delayed Onset Muscle Soreness (DOMS). Delayed Onset Muscle Soreness: The Silent Saboteur of New Year Resolutions Just like the name says, Delayed Onset Muscle Soreness (DOMS) is that delayed soreness that creeps in after rest—usually after putting your muscles through more work than they’re used to. It doesn’t hit right away. No, DOMS is sneakier than that. It waits a day or two before announcing i...

Many people do not know this… Being born into a family - as a twin or an individual does not mean you would have the same experiences.  Imagine a John Doe family - with a father, a mother, and three children. The three children create their own families and have their kids, and then the family tree continues. Yet with all the generations, there is a history of low back pain - perhaps from a particular age or across a gender. What's going through your mind? It's probably a family thing, right? We would agree with you, but we dare to tell you that research has proven that while it could be a genetic factor (such as disc degeneration) or an instability of their spine that predisposes them to low back pain - there might also be other reasons. For more information on the other causes of low back pain - kindly wait for subsequent posts. There is also the probability that while the low back pain in The Doe family is genetic, some individuals would never experi...
