This week, Richard Graves is joined by Professor John Sorochan from the University of Tennessee and Alan Thomson, USA Sales Director at SIS Pitches, to explore the science behind the playing surfaces used at the highest levels of sport.

From natural grass and artificial turf to the growing use of hybrid pitches, John and Alan explain what actually happens when an athlete interacts with a playing surface – and why the relationship between the player, their footwear and the surface itself matters.

John takes us inside the testing process, explaining how researchers measure factors such as surface hardness, traction, stability and consistency, and how those measurements help inform decisions around player performance and safety.

The conversation also explores the rapid development of hybrid surfaces. Alan explains how introducing a small percentage of synthetic fibre into natural grass can reinforce the pitch, reduce surface damage and help maintain more consistent playing conditions across demanding schedules.

The pair also discuss one of the biggest challenges in modern sport: creating elite-level natural playing surfaces inside stadiums that are increasingly expected to host football, American football, concerts and other major events throughout the year.

Drawing on their work around the 2026 FIFA World Cup, they reveal how surfaces were developed to perform consistently across hugely different environments – from the heat and humidity of Miami to altitude in Mexico and cooler conditions in Canada.

They also look at the debate around artificial turf in the NFL, what research can tell us about hybrid alternatives, and where playing-surface technology could go next.

In this episode you will learn

• Why player safety depends on the interaction between the athlete, footwear and playing surface
• What researchers actually measure when testing elite sports pitches
• How surface hardness, traction and stability can influence player movement
• The difference between natural grass, artificial turf and hybrid playing surfaces
• Why hybrid pitches are still predominantly natural grass despite their synthetic reinforcement
• How hybrid systems can create greater stability and consistency as a pitch begins to wear
• How playing surfaces were developed for very different climates during the 2026 FIFA World Cup
• Why achieving consistent ball and player interaction across different stadiums is so important
• How multi-use stadiums are changing the demands placed on grounds teams and playing surfaces
• Why shallow hybrid stitching has opened up new possibilities for temporary and replaceable surfaces
• What elite sport can learn from the ongoing debate around artificial turf and player safety
• How research, technology and experienced pitch managers work together to produce elite surfaces

If you’ve ever wondered how a club without the financial muscle of Europe’s giants consistently outperforms bigger teams, beating Nottingham Forest away, winning at Celtic, and challenging at the top of the Danish Superliga, this conversation tells you exactly how they do it.

Niklas is a rare blend of passion, creativity and evidence-based practice. His presentation at a recent Catapult event had the entire room hooked, and this episode delivers the same energy. From dismantling traditional GPS limitations to redefining how football teams train for micro-actions, set pieces, and physical dominance, Niklas pulls back the curtain on the processes driving Midtjylland’s success.

This episode goes deep into the real-world application of sports science, the balance between data and intuition, and why sometimes the most powerful competitive advantage is simply learning to “solve problems without money.”

Things You Will Learn

• Why FC Midtjylland’s entire model is built on “solving problems without money” and how data gives them a competitive edge.
• How Niklas and his team dominate set pieces using Trackman technology and detailed ball-flight analytics.
• Why GPS alone is blind to football’s most important movements, and how inertial data captures the micro-actions that matter.
• How to use accelerometers, gyroscopes and magnetometers to measure real football movement quality.
• The truth about injury “prediction,” why we still don’t know athletes’ limits, and why subjective data is often your most valuable input.
• How to balance analytics with player feelings, coaching intuition, and the “eyeball test.”
• Why communication, not technology, is the biggest challenge when coaching staffs change.
• Practical ways to design training exercises that actually transfer to match actions (including why traditional rondos may be overrated).
• How to create buy-in across departments in fast-moving environments with shifting coaching teams.
• Why the best decisions come from leading with data first, then layering coaching opinions on top.
