Rethinking Recovery Through Biomechanics with Dr. James Brouner

What does it take to truly understand recovery? For Dr. James Brouner, Senior Lecturer and Course Director of Sport Science at Kingston University, the answer goes far beyond the classroom. With over a decade teaching biomechanics and movement analysis and years of ultramarathon racing under his belt, Brouner brings a perspective that is equal parts science and lived experience.

Sometimes, a career in sport begins with a setback. For him, it started with an injury that changed everything.

As he reflects, “I have always enjoyed participating in sport… Unfortunately, I had a large injury playing rugby at age 13, a triple fracture to my femur." That moment didn’t pull him away from sport; it redirected him.

During recovery, his interest shifted toward understanding the body, healing, and performance. What began as curiosity about physiotherapy evolved into a deeper fascination with sports science and eventually, biomechanics.

He explains how that focus took shape: “Biomechanics became a focal point due to its direct link to understanding movement and the impact of load… and because it had the best equipment to play with; such as 3D motion capture and isokinetic dynamometry. ”

That same curiosity continues to drive his work today: exploring how movement works, how technique develops, and how performance can be improved both in sport and beyond. 

Making Science Useful: Turning Data into Movement

Biomechanics, by nature, can feel complex. Numbers, force outputs, motion tracking, and mathematical analysis can easily become overwhelming or abstract, especially for students encountering these concepts for the first time.

But Brouner’s approach is grounded in practicality. As he puts it, Ensuring that the data is translated into a digestible language is the approach I find most useful.”

For him, the key lies in taking complex themes and relating them directly to movement. By doing this, the information becomes more tangible and offers a greater understanding for students, performers, and coaches alike. He also emphasizes the importance of delivering key data through examples and processes that enhance the embodied experience, helping learners not only understand the science, but also connect with it in a practical and meaningful way.

Rather than focusing purely on analysis, his approach aims to make biomechanics something people can feel, apply, and use within real movement and performance environments.

What Fatigue Really Does to the Body

Fatigue is often described as tiredness, but from a biomechanical perspective, it's something more precise. It changes how the body moves, and this can vary depending on the athlete and the sport. 

As fatigue sets in during endurance activity, Brouner explains, "We see changes associated with a reduced output from slower movements and less power generation." The body still wants to perform, but the muscles can no longer maintain the same force development. That gap is where problems begin

But it doesn't stop there. He adds, "Fatigue can change technique and therefore movement patterns… placing additional stress on tissues." In other words, it's not just that you're tired. Your body starts moving differently and less efficiently.

There's also a neurological side to this. Fatigue can slow the body's ability to initiate muscular action, which reduces how quickly it can react to stress. A simple example: a fatigued runner is more likely to roll an ankle because the corrective response to an unstable surface comes too late.

Recovery Isn’t Passive. It’s Active.

There’s a common assumption that recovery simply means rest. Sit down, stop moving, and wait it out.

But Brouner challenges that idea directly. "Rest is an important part of recovery, but research supports a more active and engaged approach to recovery to expedite tissue recovery and adaptation." 

Recovery, in his view, is "a huge area with lots of systems at play to ensure someone is ready to perform/train again within a set timeframe." And it starts earlier than most people think. "Nutrition can start from a pre-covery perspective with a sound diet and nutritional strategies, such as antioxidant supplementation, supporting the body to have the tools to recover." He's equally clear on what follows training: "Ensuring you have the necessary nutrients to support recovery is critical alongside the post training diet."

On the mechanical side, he notes that recovery strategies "aid to enhance blood flow in key areas to aid with the removal of waste products and support the delivery of key metabolites to tissues." In practice, this looks like movement. "Simple methods such as walking in recovery will support enhanced blood flow," alongside "compression, manual or passive via pneumatic devices, and sport massage." He adds that "the multifaceted approach to recovery needs to consider nutrition and fluid intake too."

Ultimately, "recovery strategies are there to allow athletes to maximize their ability to retrain/perform" and it is, as he puts it, "a really important (and sometimes overlooked) area of an athlete's training plan."
And crucially, adaptation, the actual improvement, happens between sessions, not during them.

Life as an Ultramarathoner: Stress, Distance, and Discipline

That training philosophy didn't come from a textbook. 

His entry into ultra-distance running wasn’t planned. As he recalls, “In 2012 the Olympics were in London and me and some friends decided to do something to celebrate… we stumbled upon a 100-mile race along the River Thames in London to Oxford. I have been running ultramarathons ever since.”

What started as a one-off challenge quickly became a long-term pursuit. Today, he gravitates toward extreme distances, sharing, “I like very long distance races, 100–150 miles, but am currently training for a 200-mile race later in 2026.”

His training reflects that scale. “I aim to train five-six days per week… building up to the larger races, I aim to run 100-miles per week.” That volume is not just about distance, but structure; “a combination of shorter faster sessions and long race pace sessions.”

There’s also a deliberate element of training under fatigue. He explains, “For the long events it is also important to train when fatigued… I try to do one double-day per week consisting of a 20-mile run in the morning and a second 20-mile run in the afternoon.”

At this level, the feet take sustained stress. While surface-level issues like blisters are common, Brouner highlights a deeper priority: “The larger recovery point is gaining mobility back into the foot and ankle… with the repetitive load on the feet they naturally swell and this can restrict movement. Gaining mobility back enhances movement and therefore recovery.”

For him, recovery isn’t just about reducing pain, it’s about restoring function.

Where Recovery Meets Footwear

For Brouner, footwear plays a specific role, not during performance, but in the phase that follows it.

From a biomechanical perspective, he explains, “Recovery footwear needs to support movement and allow the foot to gain function… absorb some of the impact of ground contact and allow the foot space.”

That distinction matters. Performance shoes tend to wrap the foot to allow the translation of force to the floor. Recovery footwear, in contrast, needs to absorb some of the impact from ground contact and allow the foot space to move more naturally again. 

This thinking is what initially drew him to Ance. As he puts it, “Ance peaked my attention due to the multimodal approach to aid recovery in a single shoe.”

He points to how different elements work together rather than in isolation: “The combination of the wide toe-box, compressive strap to support arch development and the icing to reduce pain together make the shoe unique.”

What stands out most is adaptability. “An athlete can choose the combination of these mechanisms that work for them… quick, easy to use and accessible systems.”

In practice, that translates into notice-able changes post-training. “I find the wide toe-box allows my feet to be comfortable and allows movement to be drawn back into my feet. I also love the feel of the 360 arch support to both allow a compressive component to my feet and also support the natural position of the arch, further enhancing foot movement. I find the shoes aid in recovery by allowing me to move more naturally quicker post run.”

It’s not about adding more structure, it’s about giving the foot the right environment to recover.

Recovery, But Still Moving

One idea comes up repeatedly in Brouner’s thinking: recovery shouldn’t mean complete stillness.

He challenges the traditional mindset directly, saying, “The ‘recovery is rest’ ethos needs to be shifted, Ance offers a way to remain active whilst supporting recovery”

Research, and his own experience, point toward a more active approach. Light movement supports circulation, helps clear metabolic waste, and restores mobility faster than complete inactivity.

He explains earlier that even simple actions, like walking can “support enhanced blood flow aiding tissue recovery.” When combined with strategies like compression or massage, recovery becomes something you actively support, not passively wait for.

Tools that enable this kind of recovery, especially those that allow movement without additional strain, become important. In his own routine, recovery-focused footwear plays that role, helping him transition from fatigue back into natural movement more efficiently.

The Bigger Picture: What Most People Miss

When asked what athletes or dancers consistently overlook, Brouner’s answer is clear and grounded in both science and experience.

“Build functional recovery into your training.”

It’s not something separate from training, it’s part of it.

He expands on this idea, noting that adaptation happens between sessions. Without proper recovery, the body doesn’t fully absorb the work being done.

“Adaptation occurs between sessions, make space for it and support your recovery and adaptation through targeted recovery strategies across mechanical, nutritional and psychological processes.”

This is where many people fall short. They focus on effort, intensity, and volume, but overlook the systems that allow the body to come back stronger.

In reality, long-term progress isn’t just about how hard you train. It’s about how well you recover and how consistently you support that process.

Conclusion

Dr. James Brouner’s work sits at the intersection of science and lived experience. He studies movement, but he also tests it, mile after mile, race after race.

And across both worlds, one idea remains consistent: recovery is not a break from training. It’s what makes training work.

Whether you’re running, dancing, or simply staying active, the way you recover shapes how you move next.
