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.
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.
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.
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. She holds a PhD in Chemistry from the Technion – Israel Institute of Technology, and previously held the Blavatnik Fellowship at the University of Cambridge.

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.
In this episode you will learn
About Matthew Ibrahim
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.
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. His work covers linear speed, multidirectional movement, acceleration, maximum velocity, deceleration, curved sprinting and conditioning for team-sport athletes.
Alongside his coaching and research, Matt regularly shares practical information about speed development and the use of sports science within high-performance environments. He is also preparing a forthcoming book focused on speed development for team-sport athletes.

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.
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.
