Why Achilles Tendon Ruptures Are Increasing in Weekend Warriors - And How to Avoid One
“I Was Just Playing Social Sport…”
This is how the story usually starts.
Someone’s out playing rugby, netball, or going for a run. Nothing unusual. They go to push off, maybe to sprint or change direction, and suddenly:
“It felt like someone kicked me in the back of the leg.”
They turn around… and no one’s there.
That’s an Achilles tendon rupture.
And here’s the part most people don’t expect—it’s not usually happening to professional athletes. It’s happening to everyday people. People with jobs, families, and just enough time to stay active when they can.
The weekend warrior.
Achilles Injuries Are Becoming More Common
Over the past few decades, there has been a steady increase in Achilles tendon ruptures. Data illustrates this fact and the cost to ACC and the NZ health system is increasing as a result.
The pattern is clear. The people most affected aren’t elite athletes—they’re people in their 30s, 40s, and 50s who are doing their best to stay fit and active.
You might recognise yourself in that.
You train when you can. You try to stay consistent. But life gets busy, and sometimes your training becomes a bit stop-start. Then when you do get the chance to play or exercise, you go all in.
And that’s where the problem can start.
It’s Not Effort — It’s Preparation
Most Achilles injuries don’t happen because someone did something reckless. They happen because the tendon wasn’t quite ready for the load it was asked to handle.
When you run, jump, or change direction, your Achilles is dealing with forces that can be six to eight times your body weight. That’s a huge demand.
If your strength and conditioning haven’t kept pace with that demand, something has to absorb the stress. And often, it’s the tendon that takes the hit.
Why This Shows Up More in Your 30s and 40s
Your body is still very capable as you get older, but it does change.
Tendons don’t quite behave the same way they did in your 20s. They lose a bit of their elasticity, and they don’t recover as quickly. They still respond really well to training—but they need the right type of loading, done consistently.
The challenge is that many people are still trying to perform at a high level without adjusting how they prepare for it.
So you end up asking your body to do a lot… without giving it the foundation it needs.
“My Calves Are Just Tight…”
This is something we hear almost every day.
People come in saying their calves feel tight, and they’ve been stretching them, trying to loosen things up.
But often, that tightness isn’t a flexibility issue.
It’s your body telling you something else.
It can be a sign that your tendon isn’t tolerating load well, or that your calf muscles aren’t as strong as they need to be. It might even be an early warning that the system is under stress.
Stretching alone won’t solve that.
What your Achilles really needs is capacity—the ability to handle the loads you’re putting through it.
The Good News — This Is Preventable
Achilles ruptures can feel like they come out of nowhere. But when we assess people properly, there are almost always signs that were there beforehand.
We see patterns like reduced strength and increased stiffness, differences between one side and the other, and a reduced ability to handle fast or explosive movements.
The important thing is that these aren’t random findings. They’re measurable. And once you can measure them, you can improve them.
How We Test Your Achilles at Recovery Room
This is where we take a slightly different approach.
Rather than guessing or relying on how something “feels,” we actually measure how your Achilles and calf complex are performing.
We start by looking at your calf strength. This gives us a baseline of how much load your system can handle. But we don’t just look at strength in isolation—we look at how that strength compares to your body weight and whether both sides are working equally.
From there, we look at how your tendon behaves under more dynamic conditions. Your Achilles isn’t just a passive structure—it acts like a spring. It needs to store and release energy efficiently when you move.
Using force plate testing, we can get a really clear picture of how well your tendon is doing this. We can see how it responds to speed, load, and impact, and whether it’s actually prepared for the demands of your sport or activity.
For most people, this is the first time they’ve ever had this level of insight.
So How Do You Know If You’re At Risk?
This is the question most people ask.
And the reality is, it’s not always obvious until you take a closer look.
That’s exactly why we created our Achilles Injury Risk Checklist.
It’s a simple way to step back and assess your situation. It looks at your activity levels, how consistent your training is, what your body has been telling you, and some basic indicators of strength and performance.
