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.

Few people are better placed to chart the evolution of sports science in professional football than Simon Grayson. Across a career spanning five decades, Simon has experienced the game as both a player and manager, from an era of bacon sandwiches before training and beers on the team bus, through to the GPS data, individualised programmes and specialist performance departments that are now part of everyday professional football. This week, Richard Graves sits down with Simon to discuss how that transformation has changed the way players train, recover and prepare for matches, and how his own approach to management has evolved alongside it. Simon explains what he wants from sports science practitioners as a manager, why information has to be relevant rather than simply available, and why data should always be understood within the context of what actually happened on the pitch. They also explore one of the challenges facing modern performance teams: finding the right balance between objective data and a coach's experience. Simon discusses why high-speed running is one of the metrics he pays particular attention to, how physical data can influence team selection during congested schedules, and why he has never wanted his training sessions to be dictated entirely by the numbers. Drawing on his experiences in English football and coaching overseas, Simon also explains how climate, culture and the physical capabilities of players can force coaches to adapt their methods. And despite everything that has changed, he believes one part of coaching remains as important as ever: getting the best out of people. In this episode you will learn How sports science in professional football has changed since Simon began playing in the 1980s What a manager actually wants from sports science and performance staff Why more data doesn't necessarily mean better information Why Simon pays particular attention to high-speed running How physical data can influence selection during congested fixture schedules Why training load data needs to be interpreted within the context of the game How managers balance sports science recommendations with coaching experience What modern recovery looks like compared with previous generations How Simon adapted his training methods when coaching in different climates and cultures Why man-management and relationships remain fundamental regardless of advances in technology About Simon Grayson Simon Grayson has spent more than four decades in professional football as a player, coach and manager. After beginning his career at Leeds United, he went on to play for clubs including Leicester City, Aston Villa, Blackburn Rovers and Blackpool. His playing career included promotion to the Premier League with Leicester and victory in the 1997 League Cup. As a manager, Simon has led clubs including Blackpool, Leeds United, Huddersfield Town, Preston North End, Sunderland and Bradford City, with promotion-winning campaigns at several clubs. His career has also taken him overseas, giving him experience of working with players and performance teams in different footballing cultures and environments. More recently, Simon has worked in international football and advisory roles, while also launching the Simon Grayson Football Academy in Leeds.

Are elite athletes training harder than the demands of their sport require? This week, Richard Graves is joined by performance coach Colin Byrne, who spent seven years working with Conor McGregor as part of his training and corner team. Colin believes many athletes, particularly in combat sports, still confuse doing more work with preparing effectively. He explains why conditioning should reflect the actual structure of competition, how fatigue affects technical execution and why the ability to recover between intense efforts can decide contests. The conversation explores Colin’s work with McGregor following his first defeat to Nate Diaz. He describes how introducing greater structure, separating skill development from conditioning and helping McGregor understand his own intensity transformed the preparation for their rematch just 14 weeks later. Colin also introduces his “one-round principle”, challenges the value of routinely exceeding competition distances in training and explains what combat sports can learn from cycling’s measurement-led approach to performance. In this episode you will learn Why many combat athletes train too much without training specifically enough How fatigue affects decision-making and technical execution What Colin changed after Conor McGregor’s first fight with Nate Diaz Why skill training and conditioning may need to be separated How heart rate and power data can help athletes understand pacing Why recovery between high-intensity efforts matters so much How the “one-round principle” changes the structure of fight preparation Why training beyond the demands of competition is not always productive What coaches can learn from cycling’s approach to measurement How amateur athletes can make better use of limited training time About Colin Byrne Colin Byrne is a performance coach, martial artist and founder of the Shinobi Academy in Portugal. A former professional cyclist and European silver medallist in Brazilian jiu-jitsu, he holds black belts in both Brazilian jiu-jitsu and ninjutsu. Colin spent seven years travelling and working with Conor McGregor, helping to structure his conditioning following the first Nate Diaz fight and supporting him as a trainer and cornerman. His approach combines practical coaching experience, measurable performance data and a detailed understanding of the demands placed on combat athletes.

Elite teams have access to more performance data than ever. The real competitive advantage, however, comes from knowing which questions to ask, how to interpret the answers and when to act. This week, Richard Graves is joined by Jamie Hepner, Director of Applied Sport Science – Football Performance at Catapult. Drawing on almost 12 years of working with leading NFL and college football programmes, Jamie explains how applied sports science has progressed from simply monitoring athletes to actively shaping training and practice. The conversation explores how performance teams can combine wearable data, video and practitioner judgement to manage player availability without leaving athletes underprepared. Jamie discusses why training load cannot be viewed in isolation, how deviations at individual and positional-group level require different responses, and why feeling tired after a demanding training block is not necessarily a negative outcome. Jamie also explains how technology such as Vector 8 is connecting physical performance data with the tactical context of practice. This allows practitioners to examine the demands of particular plays, automate player participation and prescribe the type and number of repetitions an athlete may need during the week. This is a practical discussion about moving beyond interesting information and using data to make decisions that improve preparation, availability and performance. In this episode you will learn What applied sports science looks like within NFL and college football Why the quality of the question determines the value of the data How player tracking and video can provide greater context around physical demands Why minimising training load does not necessarily reduce injury risk How performance teams balance player availability with adequate preparation How wearable data can help prescribe practice rather than simply review it Why individual and positional-group deviations require different responses How subjective athlete feedback and objective performance data work together Why fatigue and soreness can sometimes be an intended training response How practitioners can turn performance information into decisions coaches can use Why the next stage of athlete monitoring is likely to focus on context rather than data volume About Jamie Hepner Jamie is Director of Applied Sport Science – Football Performance at Catapult He works with leading American football programmes to help practitioners and coaches apply athlete-monitoring data to training, preparation and player-availability decisions. During almost 12 years at Catapult, Jamie has helped the company respond to the evolving performance needs of NFL and college football teams. Originally from Australia, Jamie relocated to the United States when he joined Catapult during the company’s early expansion into American sport. His previous experience includes athlete management with AFL Victoria and strength and conditioning coaching.

What does it take to build a genuinely integrated high-performance programme? This week, Richard Graves is joined by Dr Trevor Short, Senior Associate Athletics Director for Health, Wellness and Performance at Utah State University. Trevor explains how Utah State is bringing sports science, sports medicine, strength and conditioning, nutrition and mental wellness together around three shared objectives: athlete availability, performance development and readiness to compete. The conversation explores why alignment must come before data, how monitoring should respond to the questions coaches are actually asking, and why collecting more information does not automatically lead to better decisions. Trevor also discusses the challenge of balancing performance development with athlete availability, adapting thresholds to the demands of the season and communicating the same evidence differently to coaches and senior leaders. This is a practical discussion about designing high-performance systems in which every intervention has a purpose, departments work beyond their traditional silos and the athlete remains at the centre of decision-making. In this episode you will learn Why athlete availability, performance and readiness can be competing objectives How Utah State is integrating its performance, medical, nutrition and mental wellness teams Why alignment with coaches should come before collecting data How to build monitoring systems around meaningful performance questions Why readiness flags must be interpreted within the context of the season How multidisciplinary teams can make better decisions for individual athletes Why the same information should be communicated differently to coaches and administrators How standard operating procedures can make performance systems more consistent and measurable Why leadership, culture and trust matter as much as technology How integrated athlete support can increase a team’s chances of winning About Trevor Short Dr Trevor Short is Senior Associate Athletics Director for Health, Wellness and Performance at Utah State University, where he oversees sports medicine, strength and conditioning, sports nutrition, mental wellness and sports performance. Before joining Utah State, Trevor worked as a performance and sports scientist at the University of Hawai‘i, supporting sports science provision across its intercollegiate programmes. His career has also included strength and conditioning, applied research, university teaching, private-sector performance coaching and operational leadership. Trevor holds a PhD in Kinesiology and is a Certified Performance and Sport Scientist and Certified Strength and Conditioning Specialist through the NSCA. His work focuses on integrated high-performance systems, athlete monitoring and the use of evidence to improve athlete availability, readiness and performance.

This week, Richard Graves is joined by Dr Alicia Naser, behavioural scientist and founder of The Naser Institute for Behavioral Sports Psychology. Dr Naser works with professional athletes and organisations across hockey, tennis, baseball, basketball and golf, helping them understand the relationship between behaviour, physiology and performance under pressure. In this episode, she explains why mental performance should not sit separately from physical preparation, and how fatigue, heart rate, self-talk and emotion can all influence an athlete’s ability to execute when it matters. The conversation explores the practical value of becoming more aware of internal responses during competition. From using frustration constructively rather than trying to suppress it, to striking the right balance with wearable data, Dr Naser offers a behavioural-science lens on high-performance sport that will be useful for practitioners, coaches and athletes alike. In this episode you will learn Why mental health and mental performance are related, but not the same thing How physical fatigue can affect clarity, decision-making and execution The relationship between heart rate, anxiety and an athlete’s self-talk Why emotional awareness can itself be a useful performance intervention How frustration can be used to create focus and competitive intent Where breathing strategies fit within performance under pressure How to use wearable data without becoming overly dependent on it Why mental and physical preparation should be integrated across a performance programme How practitioners can use pre- and post-intervention data to build organisational buy-in A simple journalling exercise athletes and coaches can use to identify performance barriers About Dr Alicia Naser Dr Alicia Naser, PhD, BCBA-D, is a behavioural scientist, Board Certified Behavior Analyst and founder of The Naser Institute for Behavioral Sports Psychology.

This week, Richard Graves is joined by Dave Emsley, physiotherapist and movement specialist at The Body Mechanics, for a practical conversation on why successful rehabilitation needs to look beyond the site of pain. Dave explains how the body adapts around injury, why a scan or strength test is only one part of the picture, and what practitioners can learn by observing how an athlete actually moves. From hamstring tears and persistent knee pain to golf swings, fast bowling and return-to-play decisions, this episode explores the relationship between biomechanics, motor patterns and long-term performance. The discussion also unpacks “adaptive potential”: the body’s remarkable ability to find a way to keep performing when something is not working as it should. But that capacity is not unlimited. For practitioners, the challenge is recognising when an athlete’s compensations are taking them closer to the gutter and helping them restore better options before another area of the system breaks down. In this episode you will learn Why pain should be treated as information, rather than simply the problem to remove How movement compensations can shift load elsewhere in the kinetic chain Where scans, strength testing and force-plate data fit within a complete assessment Why data should help confirm a clinical decision, rather than make it in isolation The difference between quantitative testing and the qualitative assessment of movement What “adaptive potential” means for injury risk, performance and longevity Why athletes with the same diagnosis may need very different rehabilitation plans When technical changes are worth making—and when practitioners should protect an athlete’s existing strengths Why return-to-play should account for the athlete’s actual performance demands, not just symptom resolution How practitioners can use movement quality to guide more individualised rehabilitation About Dave Emsley Dave Emsley is a physiotherapist and movement specialist at The Body Mechanics. With a background in sports science and physiotherapy, he works with athletes across a range of sports, including golf and football, and consults with Premier League footballers. His work focuses on biomechanical assessment, movement patterns, rehabilitation and helping people return to performance with a better understanding of how their body moves.

Tennis players need far more than clean technique and a strong forehand. They need to be fast, powerful, durable and able to recover well enough to perform across an unpredictable, year-round competitive schedule. This week, Richard Graves is joined by Joshua Dragone, Head of Athletic Development at Dukes Meadows Tennis Academy, to explore what effective physical development looks like in tennis. Joshua explains why tennis S&C demands a different approach: players may be travelling, competing, dealing with limited gym access or adjusting plans after every match. He shares how he identifies the key physical qualities to target, creates structure without becoming rigid, and helps young players build the recovery, hydration and fuelling habits that support long-term development. The conversation also looks at maturation, the influence of social media on junior training, and why parents, tennis coaches and athletic development coaches need to be aligned around the individual athlete. In this episode you will learn Why tennis requires athletes to develop speed, power, change of direction, robustness and energy-system capacity at the same time. How to plan physical preparation around an unpredictable tournament schedule. How to identify the one or two physical priorities that matter most for an individual player. Why growth and maturation should shape expectations and programming in junior tennis. How to use training windows effectively when players are travelling and competing. The role of sleep, hydration and fuelling in availability, recovery and performance. Why junior tennis players are often under-fuelled — and how practitioners and parents can help. How consistent warm-up and recovery routines reduce friction on competition days. How to respond constructively when players want to copy professional athletes’ social-media training. Why alignment between player, parent, tennis coach and S&C coach is essential. About Joshua Dragone Joshua Dragone is the Head of Athletic Development at Dukes Meadows Tennis Academy in West London. He joined the academy in 2021 as a Senior Athletic Development Coach and moved into his current role in 2022.

How much of an athlete’s performance is shaped by the materials they wear and use? This week, Richard Graves is joined by Dr Sarah Karmel, Chief Science Officer at RHEON Labs, to explore how dynamic materials are changing the way sport thinks about protection, comfort and performance. Sarah explains the science behind RHEON’s non-Newtonian polymer technology: materials that remain soft and flexible at rest, but stiffen to manage energy when exposed to force. From NFL helmet components designed to address both linear and rotational impacts, to sports bras that provide support without unnecessary compression, this is material science with practical implications for athletes. The conversation also looks at vibration damping in tennis and padel rackets, the role of apparel in supporting movement, and why the next step in sports equipment may be creating products that adapt to the athlete, rather than asking the athlete to adapt to the product. In this episode you will learn How dynamic polymers respond differently at rest and under force. Why managing both linear and rotational impacts matters in athlete protection. Why repetitive lower-energy impacts are receiving greater attention in contact sport. How sports bra design can influence comfort, movement and the running experience for female athletes. How dynamic materials can reduce vibration in rackets without removing the feel athletes need. The potential role of responsive compression apparel in muscle support and tendon loading. Why energy management is the common thread linking helmets, apparel and sporting equipment. How material innovation could make sports equipment more individualised and athlete-centred. About Dr Sarah Karmel Dr Sarah Karmel is Chief Science Officer at RHEON Labs, where she leads the development of advanced elastomeric materials for sport, protection and performance applications.

Richard Graves welcomes Dr Matthew Ibrahim back to the Science for Sport podcast to discuss how sports science, strength and conditioning, athlete monitoring and wellness can be brought together within one integrated performance model. Matthew explains how he is applying this approach in his new role as Assistant Athletic Director of Health, Performance and Wellness at Malden Catholic. Rather than collecting data simply because the technology is available, his focus is on asking better questions, identifying the measures that genuinely inform decisions and presenting information in a way that athletes, coaches, parents and support staff can understand. The conversation explores the difference between returning an athlete to play and returning them to performance. Matthew discusses how force plates, isometric strength testing, sprint timing, velocity-based training and subjective wellness measures can contribute to a criteria-based process, while emphasising that every test must have a clear purpose. Matthew also introduces his new Science for Sport course, Frontal Plane Fundamentals: Lower Body Training. He explains why lateral strength and movement are often underdeveloped, the importance of the adductors in athletic performance and how simple lateral squat and lunge progressions can be incorporated into a training programme. In this episode you will learn How to connect sports science, strength and conditioning, education and wellness within one performance model Why collecting more data does not necessarily produce better decisions How to identify the performance tests and monitoring measures that matter most The difference between return to play and criteria-based return to performance How practitioners can prepare athletes for sudden increases in training and competition load Why frontal-plane strength is important for running, cutting, skating and changing direction How lateral squats and lunges can develop the adductors and improve athletic movement Why relationships, trust and communication are essential when building athlete buy-in About Matthew Ibrahim Dr Matthew Ibrahim is the Assistant Athletic Director of Health, Performance and Wellness at Malden Catholic in Massachusetts. He has more than 15 years of experience across strength and conditioning, human performance, education and sports rehabilitation.

His work centres on making performance science understandable and useful, helping athletes develop the physical skills, confidence and habits needed to perform in sport and beyond.

Speed in American football is about far more than running a fast 40-yard dash. It is the ability to create space, close space, accelerate, decelerate, change direction and repeatedly produce high-speed actions under the demands of the game. This week, Richard Graves is joined by Matt Gebert, Strength and Conditioning Coach at Ole Miss Football, to explore how speed is developed within an elite college football programme. Matt explains how Ole Miss structures speed training across the week, from acceleration and change of direction to maximum velocity, curved sprinting and conditioning. He also breaks down how the physical demands change between position groups and why offensive linemen, linebackers, running backs, wide receivers and defensive backs require different training priorities. The conversation explores the five key qualities Matt uses to assess speed development and how tools including Catapult GPS and the 1080 Sprint can help coaches understand an athlete’s strengths, weaknesses and potential performance limiters. However, collecting more data does not automatically lead to better decisions. Matt explains why sports science technology must be accurate, efficient and actionable, particularly when working with a squad of around 120 athletes within strict time restrictions. Richard and Matt also discuss the balance between pushing athletes hard and protecting player availability, the value of wellness monitoring, the importance of sleep and why technology should help practitioners ask better questions rather than replace coaching judgement. Matt also reflects on how his coaching philosophy has changed during more than a decade in college football, including moving away from one-size-fits-all programming and learning to coach athletes differently, both physically and psychologically. In this episode you will learn Why speed in team sport is ultimately about creating and closing space How Ole Miss structures acceleration, maximum velocity, change of direction and conditioning work Why different football positions require different speed and strength qualities The five physical qualities Matt assesses within speed development How Catapult GPS and the 1080 Sprint are used to profile athletes Why maximum velocity is particularly important for wide receivers and defensive backs How to identify and improve an athlete’s performance limiters The difference between using sports technology and practising sports science The three questions Matt asks before introducing new technology How external and internal training loads can inform programme decisions Why wellness questionnaires can start important conversations with athletes The relationship between training load, recovery and player availability Why sleep may be the most overlooked performance metric How Matt’s approach to individualising training and communication has evolved Why acceleration should be a priority for young athletes in almost every sport About Matt Gebert Matt Gebert is a Strength and Conditioning Coach with Ole Miss Football, where he leads speed development work within the programme’s performance team. Matt has worked in college football for approximately 13 years and is currently completing a PhD focused on speed development.

In this episode of the Science for Sport Podcast, Richard Graves welcomes back Dr Warren Bradley, Co-Founder and Head of Elite Performance at Hytro, to explore how blood flow restriction is being used at the highest level of sport. With the biggest World Cup in history placing huge demands on players, staff, travel logistics, recovery windows and match preparation, Warren explains where BFR now fits inside elite performance environments. This conversation goes beyond the basic idea of BFR as a recovery tool. Warren breaks down how it can be used to support circulation, tissue preparation, injury risk reduction, return-to-play, long-haul travel strategies and squad-wide recovery workflows. He also discusses the challenge every practitioner will recognise: how to balance research, data, individualisation and real-world practicality when time is limited and performance outcomes matter. For coaches, sports scientists, physios and performance staff working in elite sport, this episode gives a clear look at how BFR is being applied in tournament football and why the next stage of recovery science may be less about collecting more data, and more about using meaningful interventions consistently. In this episode you will learn What blood flow restriction is and why its application has changed in elite sport How BFR can be used for recovery, tissue priming, warm-ups and travel support Why long-haul travel creates a major performance challenge during tournament football How teams are adapting BFR protocols to fit real-world environments, including pools, the sea, flights and pitch-based warm-ups Where BFR can help bridge the gap between low-grade injury and return-to-pla Why Warren believes circulation is becoming a major focus in modern recovery science How elite teams balance scientific precision with practical use across a full squad Why highly specific numbers can sometimes become a barrier to implementation How BFR protocols can be individualised without overcomplicating delivery What Warren would study if he had unlimited access to World Cup players, wearables and performance data About Dr Warren Bradley Dr Warren Bradley is Co-Founder and Head of Elite Performance at Hytro, a company specialising in wearable blood flow restriction technology for performance, recovery and rehabilitation.

Richard Graves welcomes Dr James Morehen back to the Science for Sport podcast for a practical conversation on what it really takes to work in elite performance nutrition. James reflects on his journey from Liverpool John Moores University to rugby league, England football, Premiership rugby, international rugby, and his current work with England Rugby. But this episode is less about the polished version of elite sport, and more about the details that actually make performance environments work. From gaining experience as a student, to building a trusted network, to solving problems on tour before they affect the athletes, James gives a clear view of the craft behind applied performance nutrition. He explains why degrees matter, but why they are only part of the picture, and why students and early-career practitioners need to get into clubs, support research, present to athletes, make mistakes, and learn from them. James also shares examples from inside elite sport, including heat strategies, travel logistics, hydration planning, making weight for combat athletes, and the hidden operational details that can decide whether a practitioner is adding real value or simply reacting under pressure. This is a valuable episode for sports nutritionists, sports scientists, S&C coaches, performance directors, students, and anyone interested in the reality of working behind the scenes in high-performance sport. In this episode you will learn Why academic knowledge is essential, but not enough on its own How students can build meaningful experience while still at university Why volunteering, research participation, and applied placements can separate candidates in a crowded field What James looks for when interviewing or mentoring young practitioners How to build a professional network that genuinely improves your practice Why elite sport often comes down to simple details done exceptionally well How practitioners use networks to check, challenge, and improve strategies What travel, heat, hydration, and logistics look like inside international rugby Why mentorship matters at every stage of a practitioner’s career How James is now helping clubs and practitioners develop better nutrition systems About Dr James Morehen Dr James Morehen is a performance nutritionist working at the highest level of elite sport.

This week on the Science for Sport Podcast, Richard Graves welcomes back Steve Jennings for part two of one of the most fascinating stories in sports nutrition. Earlier this year, Steve joined us to tell the story of how creatine first entered the world of elite sport ahead of the Barcelona 1992 Olympic Games. In this follow-up conversation, Richard and Steve look at where creatine goes next. For decades, creatine has been viewed primarily as a strength, power and high-intensity performance supplement. But Steve believes the next phase of creatine will move far beyond the gym, the track and the changing room. In this episode, Steve discusses the emerging research around creatine, cognition, fatigue, brain function, sleep deprivation, concussion, ageing, women’s health, shift work and everyday human performance. He also explains why education is now critical, particularly for youth athletes, parents, schools and practitioners who need to understand creatine in the right context. The conversation also explores the future of creatine as an ingredient technology, with Steve outlining how new forms of creatine could be used in functional foods, gummies, drinks and other products designed for wider health and performance benefits. This is a conversation about sport, science, innovation and the changing role of creatine in human performance. In this episode you will learn How creatine moved from elite sport into mainstream performance nutrition Why Steve believes the biggest future breakthroughs may come outside traditional sports performance The potential role of creatine in cognition, fatigue, brain function and sleep deprivation Why education is so important when discussing creatine with youth athletes and parents How practitioners can better frame creatine use in the right context Why Steve believes three grams per day can be enough for many users How creatine needs may change across the lifespan Why creatine is becoming a major topic in women’s health, ageing and longevity The challenges of creating liquid-stable and food-based creatine products How ingredient technology could shape the next generation of creatine products About Steve Jennings Steve Jennings is one of the most influential figures in the history of sports nutrition. A former professional racing cyclist, Steve founded Maxim Sports Nutrition in the early 1990s and played a key role in introducing creatine supplementation to elite sport ahead of the Barcelona 1992 Olympic Games. Over the last three decades, Steve has built, launched and developed nutrition brands across performance sport, active lifestyle and human health. Today, through Jenerise, he is focused on the next chapter of creatine: helping expand its role beyond traditional strength and power performance into cognition, vitality, healthspan and everyday human performance. Steve brings a rare combination of lived sporting experience, commercial innovation and deep understanding of how science can be translated into practical, real-world use.

This week, Richard Graves is joined by Anna Cruse, Assistant Athletics Director for Applied Health and Performance Science and Director of Football Performance Science at the University of Utah. Anna’s route into sports science began as an international-level rower. Her interest in training, performance and data eventually took her from competing for the United States to helping develop the systems that support athletes across 19 sports at Utah. In this episode, Anna explains how Utah has moved from manual data exports and generalised reporting to faster, integrated workflows that deliver relevant information to coaches and practitioners. She discusses why collecting more data is not always the answer, the importance of educating decision-makers and how greater context can prevent practitioners from drawing the wrong conclusions from a metric. The conversation also explores individual athlete baselines, the limitations of fixed asymmetry thresholds and the need to make data specific to the athlete, position and sport. Anna also shares her perspective on artificial intelligence, including where it can improve performance workflows and why it should never replace qualified human judgement. In this episode you will learn How Anna moved from international rowing into applied sports science Why Utah only collects data it can use to support athletes or performance How the university delivers performance information across 19 different sports Why coaches and support staff must understand the context behind every metric How Utah has developed more sport-, position- and athlete-specific reporting Why fixed thresholds can be misleading when assessing asymmetry How integrated performance teams can make better use of limited resources Where AI can support practitioners without replacing their expertise Why athlete welfare must remain central to every performance decision How strong systems create more time for meaningful analysis About Anna Cruse Anna Cruse is Assistant Athletics Director for Applied Health and Performance Science and Director of Football Performance Science at the University of Utah. A former elite lightweight rower, Anna represented the United States at the World Rowing Under-23 Championships before moving into coaching, performance science and data analytics. Her career has included experience with the Philadelphia Union, Penn State and exercise intelligence company Svexa. At Utah, Anna helps lead the systems used to collect, interpret and communicate performance information across the university’s athletic programme. Her work focuses on turning data into useful decisions while ensuring that technology and analysis remain grounded in good science and the needs of the individual athlete.
