Are asymmetries something we should actually be fixing… or just better understanding? Chris Bishop is an Associate Professor of Strength and Conditioning and one of the leading researchers in interlimb asymmetry, bringing years of work across performance, rehab, and applied sport science.

In this conversation, Chris breaks down one of the most misunderstood topics in sports performance. From how asymmetries are calculated to whether they even matter, this episode challenges common practices in screening, rehab, and training decisions. He explores why asymmetry data is often noisy, how context changes everything, and why chasing symmetry alone may not lead to better performance or reduced injury risk.

What if you could bring lab level physiology into every training session?

Arnar Larusson is the founder of Tymewear and is working to make breathing data accessible outside the lab, giving athletes real time insight into how their body is actually responding to training.

Coming from a background in mechanical engineering and prosthetics, Arnar saw the gap between what we can measure in controlled environments and what athletes can access in the real world.

This conversation explores how ventilation and breathing patterns reveal intensity, efficiency, and stress in ways that heart rate and power alone cannot.

From identifying ventilatory thresholds to understanding fatigue and durability, this episode looks at how breathing data could reshape how we train and measure performance.

What does it take to build a career across the highest levels of sport and keep evolving along the way?

Jon Bartlett has worked across football AFL the NBA and Olympic cycling building a career shaped by curiosity adaptability and a constant drive to learn.

Rather than staying in one system Jon chose to explore different sports and environments to understand how high performance actually works in practice
From hands on roles with athletes to leading global development systems and now working in performance technology his journey shows how transferable thinking leadership and problem solving can be across completely different contexts.

This episode dives into what he learned at each stage how his role evolved over time and why stepping outside your comfort zone is often the biggest catalyst for growth.

We all “love” 😍 STRENGTH & gym training 🏋🏻 to a certain degree - but that does not mean that you CANNOT develop SPEED & STRENGTH without it!

Dr Darren Burgess want you to understand that WHOLE sport CULTURES ⚽ 🏀 🏈 have been developed over decades without having very much strength or speed specific training AT ALL. Many footballers in Europe for example barely do any gym work. Obviously that does not mean it is useless, but it is important to understand that apparently you can get good at the sport WITHOUT it.

In the 72nd episode of The Training Science Podcast, Martin and Darren discuss how:

🏛️ various sports “cultures” can be a downside or upside if you are a multidisciplinary professional;

🏋️ player specific loads are important, but you need to remember ALL the other types of load a player (and staff too!) experience - it is a whole wellbeing model;

🕛 chronic load for adaption, rehab or simply helping players to improve needs to be balanced and maintained for certain durations, but without “peaks” and “valleys”.

What if you could predict your race before you even start?

In this episode, Ryan Cooper shares the story behind one of endurance sport’s most influential tools, Best Bike Split. With a background in electrical engineering and aerospace, Ryan saw early on that the same physics used in aviation could be applied to cycling and triathlon performance.

We dive into how power meters and modeling unlocked a new way to race, why normalized power became a game changer for long course athletes, and how smart pacing can make or break your entire performance.

From early prototypes during the Tour de France to real world validation at world championship races, this episode is a behind the scenes look at how data, physics, and practical application came together to change the way athletes approach race day.

What if your biggest performance limiter isn’t your fitness, but your nervous system?

In this episode, Lawrence van Lingen shares a radically different lens on endurance performance, one that shifts the focus from traditional training metrics to fascia, breath, and vagal tone. Drawing from years of work with elite athletes like Andi Böcherer and Jan Frodeno, Lawrence explains how movement efficiency, recovery, and performance breakthroughs often come from restoring internal balance rather than pushing harder.

We explore why breathing mechanics and nervous system health are foundational to performance, how simple practices like walking and crawling-like movements can create massive changes, and why many athletes struggle not from lack of effort but from an inability to absorb training.

This conversation challenges conventional thinking and offers a new way to approach performance, recovery, and long term health.

What actually drives performance in professional cycling, and how much of it is science versus experience?

In this episode, Dr David Bailey joins us to unpack over two decades of work across Olympic sport and WorldTour cycling. From talent identification and training philosophy to nutrition, heat, altitude, and the evolving role of data, David shares what really matters when building high performance athletes.

We dive into the concept of marginal gains and why most people misunderstand it, how teams prioritize what actually moves the needle, and why talent and training still outweigh everything else. The conversation also explores real world applications of AI, individualized nutrition strategies, and the complex mix of physiology, psychology, and race strategy that ultimately decides who wins.

What can heart rate variability actually tell us about training, recovery, and long term health, and where do most people still get it wrong?

In this episode, Dr Greg Grosicki joins us to unpack the science and practical value of HRV, from what it really measures to why context matters so much when interpreting it. We explore how exercise intensity, sleep, alcohol, sickness, hydration, and metabolic health can all shape HRV, and why a single daily score often tells only part of the story.

We also dive into Greg’s new work on HRV CV, a promising way to understand the stability of recovery over time, and discuss how wearables at scale are changing the kinds of questions sports science can answer.
