339: Can a Playing Surface Change How an Athlete Moves?

Science for Sport — Mon, 28 Sep 2026 06:00:00 +0100

How much does the surface beneath an athlete’s feet really affect performance and injury risk?

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

About Professor John Sorochan and Alan Thomson

Professor John Sorochan is Distinguished Professor of Turfgrass Science and Management at the University of Tennessee and one of the leading researchers in sports turf and athletic-field safety.
His career in turfgrass science stretches back more than 30 years, including working as a student on the 1994 FIFA World Cup. Today, his research examines the relationship between playing surfaces, player biomechanics, turf performance and safety.
John has worked with organisations across elite sport including the NFL, Major League Baseball and professional football, and has played a leading role in research designed to deliver safe and consistent pitches for the 2026 FIFA World Cup.

Alan Thomson is USA Sales Director at SIS Pitches and has spent his career working with elite sports surfaces.
After beginning his career in golf-course management in Scotland, Alan moved into the construction, renovation and maintenance of football pitches before joining SIS Pitches. He now works across the United States helping venues implement hybrid playing-surface technology across sports including football, American football, baseball and lacrosse.
His recent work has included major stadium projects across North America and the installation and development of hybrid surfaces used during the 2026 FIFA World Cup.

321: Preparing for the World Cup: Physical Performance Under Extreme Pressure

Science for Sport — Mon, 25 May 2026 06:00:00 +0100

The 2026 Men’s World Cup will place unprecedented demands on international teams: 48 nations, 104 matches and a tournament staged across Canada, Mexico and the United States, with teams required to manage heat, humidity, altitude, travel and limited recovery time.

In this episode of the Science for Sport Podcast, Richard Graves is joined by Dr Ben Rosenblatt, Founder of 292 Performance and former Lead Men’s Physical Performance Coach at The Football Association.

Ben draws on his experience preparing the England men’s football team for two World Cups and a European Championship, alongside his work with Olympic athletes, GB Hockey and elite performers across a range of sports.

The conversation explores what it really takes to prepare athletes for tournament football at the highest level. Ben discusses why physical preparation cannot begin when players arrive in camp, how small doses of training can create meaningful change during a tournament, and why “available” is very different from “ready to compete” when returning players from injury.

He also explains the physical and psychological challenges of competing in extreme environments, from heat and altitude to fatigue and pressure, and shares how the best performance teams use data, observation, communication and athlete understanding together to make better decisions.

For practitioners working in elite sport, this episode offers a detailed insight into preparing players not simply to take part in major tournaments, but to perform when the demands are at their highest.

In this episode you will learn

Why effective tournament preparation starts months before the first game.
How England used micro-dosed strength training during the 2018 World Cup to improve players’ power and hamstring strength.
Why athletes must continually adapt and “reinvent” themselves to sustain performance at the highest level.
How Ben used daily monitoring with GB Hockey to prepare players for the demands of eight matches in 13 days at the Rio Olympics.
Why data should be considered alongside observation, athlete feedback, staff conversations and practitioner judgement.
The difference between returning a player to availability and preparing them to compete in the decisive stages of a major tournament.
How performance teams can prepare players for heat, humidity, altitude and travel during the 2026 World Cup.
Why recovery, nutrition, strength training and sprint exposure must be individualised rather than delivered as a single team-wide solution.
How clarity, trust and pressure training help athletes execute when the stakes are highest.
What the best high-performance environments look and feel like behind the scenes.
