A hamstring strain is one of the most common — and most frustratingly recurrent — injuries in active adults. Here’s what the evidence says about why hamstrings re-injure, and how physiotherapy in Victoria BC rebuilds them so they hold.
Hamstring Strain: The Injury That Loves an Encore
A hamstring strain can happen in an instant. You were sprinting for a ball at a soccer game at Braefoot, pushing the pace on the Galloping Goose, or chasing a personal best on the track — and then it happened. A sharp grab at the back of your thigh, a stumble, and the sudden certainty that something has gone wrong. A hamstring strain announces itself clearly.
What’s less obvious is why, for so many people, it comes back. You rest, the pain fades, you return to sport — and weeks or months later, the same thigh grabs again. This recurring pattern is one of the most important things to understand about hamstring strain injuries, and it’s why a proper rehab plan matters so much.
At Pursuit Physiotherapy on Hillside Ave, we see hamstring strains in sprinters and soccer players, trail runners and weekend athletes, and active adults who ramped up their training a little faster than their bodies were ready for. The good news: with the right progressive plan, hamstrings recover well — and the re-injury cycle can be broken.
RESEARCH STAT: A prospective randomised trial in elite sprinters and jumpers found that a rehabilitation programme emphasising lengthening (eccentric) exercises returned athletes to sport in a median of 28 days, compared with 51 days for a conventional protocol — with fewer re-injuries.

What a Hamstring Strain Actually Is
Your hamstrings are a group of three muscles running down the back of your thigh, from your sitting bones to below the knee. They do two big jobs: they bend your knee, and — crucially — they decelerate your leg as it swings forward when you run. That decelerating role is where most strains happen.
During fast running, the hamstring is stretched and forcefully contracting at the same time, right at the end of the swing phase before your foot hits the ground. This is an eccentric contraction — the muscle producing force while lengthening — and it’s the moment of peak vulnerability. When the demand exceeds what the muscle can tolerate, fibres tear. That’s a strain.
Strains range from mild (a few fibres, a bit of tightness and discomfort) to severe (a significant tear with marked weakness and bruising). Most are in between.
Typical features include:
– A sudden sharp pain at the back of the thigh during a sprint, kick, or lunge
– Tenderness and sometimes bruising along the back of the thigh
– Pain and weakness when bending the knee against resistance or stretching the hamstring
– A feeling of the leg “giving” or not being trusted at speed
The location and severity guide the plan, which is one reason an accurate assessment early on is worth its weight.
Why Hamstrings Re-Injure So Often
Here’s the uncomfortable truth about hamstring strains: the biggest risk factor for tearing your hamstring is having torn it before. Re-injury rates are stubbornly high, and the reason is usually that the original injury was rehabbed to the point of feeling fine, but not to the point of being fully capable again.
When a hamstring heals, three things can be left behind if rehab stops too early: the muscle can remain weaker than its partner on the other leg, it can lose eccentric strength specifically (the exact quality it needs to decelerate the leg safely), and the healed tissue can end up shorter and less able to tolerate length. Pain resolving is not the same as capacity returning. This is why “it feels okay now” is a trap — and why we measure rather than guess.
The fix is to rebuild the specific quality the hamstring lost: strength at length. That’s the through-line of the strongest evidence, both for preventing first-time strains and for rehabbing them so they hold.
RESEARCH STAT: A systematic review and meta-analysis of 8,459 athletes found that including the Nordic hamstring exercise in injury-prevention programmes halved the rate of hamstring injuries — a 51% reduction in overall injury risk.
Source: van Dyk, Behan & Whiteley, British Journal of Sports Medicine, 2019;53:1362–1370. (Landmark meta-analysis — slightly older than five years; see caveat note.)
It’s worth being honest that the science here is active and debated. A 2021 methodological reappraisal argued that some earlier prevention estimates may have overstated the effect, concluding the evidence was less definitive than headline numbers suggest. The practical takeaway hasn’t changed much: building eccentric hamstring strength is one of the best-supported things you can do — but it’s one part of a complete plan, not a magic bullet.

Active vs. Passive Treatment: Where Pursuit Stands
After a hamstring strain, the temptation is to rest completely and wait for it to heal, perhaps with some passive treatment along the way. Both instincts sell your recovery short.
Passive treatments — machines and modalities applied while you rest — don’t rebuild the eccentric strength and length tolerance a hamstring needs to sprint safely again. You won’t find ultrasound, TENS, IFC, or laser at Pursuit. That’s a deliberate, evidence-based decision, not a gap in our services. Prolonged complete rest is just as much of a problem: it lets the muscle heal short and weak, setting up the re-injury cycle.
PURSUIT PHILOSOPHY: Quality care over quick fixes. A hamstring doesn’t recover because you waited long enough or because a machine was pointed at it. It recovers because you rebuilt its ability to produce force at length — progressively, and under a plan that’s measured, not guessed.
Active care for a hamstring strain at Pursuit starts with a short, sensible period of load management — protecting the tissue without shutting it down — and moves as soon as it’s tolerated into gentle lengthening work, then progressive eccentric loading, then running mechanics and speed. The evidence favours starting the right kind of loading earlier rather than later, staged carefully. Hands-on work supports that plan; it doesn’t replace it.

How Physio, Chiropractic, and RMT Work Together on Hamstring Recovery
At Pursuit, physiotherapy and registered massage therapy (RMT) work together through a shared active-care model. A hamstring strain is a great example of why a coordinated approach matters — because recovery isn’t just about reducing pain; it’s about rebuilding the strength, control, and capacity needed to return to sport safely.
Your physiotherapist leads the rehab plan: confirming the diagnosis and grading the hamstring strain, prescribing and progressing lengthening and eccentric-strength exercises, measuring hamstring strength side-to-side, and staging your return to running and sprinting with objective checkpoints so you don’t return before the tissue is genuinely ready.
Your chiropractor supports recovery by addressing movement restrictions, joint mechanics, and areas that may influence how your body absorbs and produces force during sport. Chiropractic care can complement your rehabilitation plan by helping optimize mobility and movement quality while your hamstring rebuilds capacity.
Your RMT prepares the ground. Skilled soft-tissue work can help ease protective muscle guarding around a healing hamstring, improve comfort, and create a better window for completing your strengthening program. It doesn’t replace the rebuilding process — but it can help you move through rehab more effectively.
THE INTEGRATION PRINCIPLE: Your RMT helps reduce protective tension, your chiropractor supports movement quality, and your physiotherapist rebuilds strength and capacity. Together, this coordinated approach helps you recover from a hamstring strain, return to full speed, and reduce the risk of the same injury coming back.
The Pursuit Approach to Hamstring Strains
Every athlete who comes to Pursuit with a hamstring strain gets one-on-one time with a clinician — no assembly-line care, no generic sheet of stretches. Here’s what that looks like:
– Define your goal. Returning to recreational soccer is a different target than chasing a sprint PB. We start with your “why.”
– Measure what matters. We assess hamstring strength — including eccentric strength — and compare side to side, so we can see the actual gap rather than trusting how the leg feels.
– Personalized pain relief. Manual therapy, dry needling/IMS where appropriate, and smart early load management to settle the tissue.
– Tailored programming. A progressive lengthening and eccentric-strength program (the Nordic hamstring exercise and lengthening-focused work are central), advanced toward running mechanics and speed.
– Retest metrics. We re-measure strength and function before each progression — especially before you return to sprinting.
– Fitness for life. We use our on-site gym to take you past “healed” and into genuinely robust, so the re-injury cycle is broken for good.
The aim isn’t just a pain-free thigh. It’s a hamstring you can trust at full speed.
Realistic Expectations for Hamstring Strain Recovery
Here’s the honest part. Hamstring recovery timelines vary a lot with the severity and location of the strain, and recovery is rarely perfectly linear. A mild strain may settle in a couple of weeks; a more significant tear can take considerably longer, and rushing back is exactly how the re-injury cycle starts. The evidence is clear that returning based on how the leg feels — rather than on measured capacity — is a mistake.
We won’t promise you a specific return date or session count; anyone who does is guessing. What we do guarantee is a thorough assessment, honest communication, an evidence-based and individualized plan, and a coordinated team. Crucially, we’ll help you return when your hamstring is genuinely ready — not just when the pain has faded.
Ready to Rebuild a Hamstring You Can Trust?
If you’ve strained a hamstring — or you’re stuck in the cycle of straining the same one again and again — the way out is a plan that rebuilds strength at length and returns you to speed on measured evidence, not guesswork.
