Tim Trevail - Jiu-Jitsu Rehab Specialist Tim is a musculoskeletal injury expert & educator with a special interest in jiu jitsu and combat sports. IG: More info at TimTrevail.com

Tim consults out Complete Physio, Exercise & Performance in Richmond, and online globally to jiu jitsu athletes of all levels. This page is designed to help you connect with me, find out more about the clinical services available, and other sports and exercise medicine resources I share to help people make sense of their pain and injuries.

​Academically, I hold an undergraduate honours degree in Sports Therapy from the UK, a Post-graduate Diploma in Learning and Teaching, a Masters Degree in Sports and Exercise Medicine, and am currently undertaking doctoral studies investigating the links between physical activity and persistent pain. I believe in being guided by the evidence and have a focus on active management (rehabilitation exercise) to ensure long term outcomes that align with the values and goals of the people I work with. I enjoy treating all sporting types, but I particularly enjoy working with jiu-jitsu and other contact sports athletes.

Should kids lift weights?

This question still creates anxiety for a lot of parents.

Most parents think lifting weights will stunt their child's growth. The research tells a different story.

The evidence is clear: youth resistance training is safe and beneficial when it is properly supervised and progressed appropriately.

What increases injury risk is not strength training itself.
It’s poor supervision, poorly controlled environments, and adult expectations applied to children.

For young grapplers, the goal is not to build elite 10-year-olds.

The goal is to build resilient, confident 20-year-olds.

If a child can follow instruction, respect safety rules, and participate in organised sport, they are often ready for structured strength training.

Share it with a parent or coach who still has questions about youth lifting.

Let’s raise the standard for long-term athlete development in grappling.

Save this if you work with young athletes. Tag a parent or coach who needs to see it. 👇

That ache in your shoulder that's "fine, just a bit sore"?

That knee that needs a longer warm-up but feels okay once you get going?

That elbow that's cranky on Mondays but loosens up by Wednesday?

Most grapplers train with something. So do niggles matter?

A season-long study in semi-professional athletes found that non-time-loss complaints—things that don't stop you training—increased the risk of a serious injury by 3–7× within the following week. Around 1 in 4 athletes reported weekly complaints, and 68% of time-loss injuries were preceded by symptoms.

That does not mean every ache is a disaster.
It means niggles are information.

Niggles often represent a temporary load-capacity mismatch. When you train hard and push your limits technically, you operate close to your tolerance. In grappling, where joints are loaded unpredictably and repeatedly, symptoms rarely get good rest.

The goal is not to panic. And it is not to ignore it.
It is to respond actively.

Track it. Adjust volume or intensity. Avoid load spikes. Modify positions that aggravate it. Add targeted strength work off the mats. Build tolerance progressively. Communicate with training partners.

Capacity is built, not rested into existence.

Niggles matter—not because they demand fear, but because they offer a window to build resilience before missed time forces the decision for you.

Most grapplers can point to the roll that started their pain.

The awkward scramble.
The late tap.
The hard round when you were already fatigued.

But the spark is only part of the story.

In high-contact sports like grappling, sparks are common. What determines whether something settles in a few days or lingers for months is often the health of the system it landed in.

Sleep.
Recovery.
Strength and tissue capacity.
Training load.
Background stress.

When your system is already under strain, small injuries feel bigger and last longer. Baseline inflammation and nervous system sensitivity increase. Tolerance drops.

That does not mean you are broken.
It means context matters.

Healthy ecosystems still get injured. They just tend to recover faster and flare less often.

So before obsessing over the exact movement that “caused” your injury, zoom out.

Where did the spark land?

In a dry, overloaded system?
Or in one resilient enough to contain it?

Rehab is not just about fixing pain.
It is about building a system that is harder to ignite — and faster to recover.

📢 New publication

This paper reports on the end product of an industry-funded project exploring how co-design with students can strengthen the usability, effectiveness and value of digital learning tools in health education.

A big thank you to Dr Amber Moore for her leadership in driving this project through to publication. It’s been nice to collaborate on work that bridges educational innovation and real-world clinical training.

Most preventable injuries come from how we train, not bad luck or “fragile” bodies.

There are many complicated theories about how injuries occur, but in my experience, they’re usually the result of load mismanagement, poor recovery, and avoidable training behaviours over time.

If we’re serious about reducing injury risk, the priorities are fairly consistent:
• managing training loads over time
• building physical capacity with sensible S&C
• respecting recovery
• and, critically, gym culture and training habits

Strength and conditioning matters.
Recovery matters.
But culture often matters more than we like to admit.

How intensity is managed.
How submissions are applied.
Whether control is valued over ego.
Whether tapping early is normalised.

Those things reduce more injuries than any warm-up or injury-prevention training program ever will.

What does your gym take active steps to reduce preventable training injuries?

Great way to start the year 🎙️

Thanks to Alpa Sonigra for having me on her new podcast, The BalanceTalk Show. A thoughtful conversation and a beautifully run recording.

We covered a range of topics including:
• Why pain is often more about tolerance and nervous system sensitivity than tissue damage
• How modern lifestyles contribute to the prevalence of tendon pain and why it is so common in adults
• The role of strength training in long-term physical health
• How sedentary patterns, load spikes, and deconditioning shape pain and injury
• Translating research into practical, everyday advice

A great opportunity to share some of my thinking on movement, pain, and prevention to kick off the year.

Alpa has some excellent guests lined up and this is definitely one to watch.

[I'll share details when it's released.]

Most preventable injuries are not tissue or rehab failures. They are culture failures.

Lack of positional awareness.
Not tapping early.
Ego-driven intensity.

These are behavioural issues, not tissue problems.

Training around injury only works when there is trust in the room. Trust to communicate limitations. Trust to respect positional constraints. Trust to prioritise technical development over winning the round.

When that trust is missing, the safer option is often to spend more time away from live rounds building physical qualities, capacity, and confidence before returning to the mats.

Good culture allows athletes to:
• Modify intensity without stigma
• Communicate clearly with training partners
• Maintain training continuity during injury
• Self-monitor load and early warning signs

Injury prevention is not something you do after rehab ends.

It is the continuation of the same principles that allowed you to return safely.

Strong culture keeps people training.

Effective martial arts require an understanding of anatomy, joint mechanics, and tissue tolerance.

The same knowledge that explains injury also explains adaptation, recovery, and performance.

Jiu-jitsu and science are complementary. That is why many cerebral athletes rise to the top of the sport, and why many health professionals are drawn to it.

Studying how the body breaks gives insight into how we can better tolerate training and spend more time doing the sport we love.

Grateful to Dr Austin Vo for the opportunity to observe ACL reconstruction last week.

It was particularly interesting to see his approach to preserving as much of the native bone tunnels as possible when using a hamstring graft. In this case, 's strength training background meant the semitendinosus alone provided adequate graft size, without the need to harvest the gracilis.

A partial meniscectomy was also performed due to a clear bucket-handle tear, which aligned with the mechanical locking symptoms Kortney had experienced prior to the surgery. While this necessitates some early rehabilitation considerations to protect the healing meniscal tissue, it is not expected to cause ongoing issues.

The surgery was a success and she is now progressing through rehabilitation, with the longer-term goal of returning to jiu-jitsu training and competition.

A valuable reminder of how intra-operative decisions directly shape the rehabilitation process that follows.
