Show Notes
This week on the Science for Sport podcast, Richard Graves welcomes Matt Parr back to the show for a deeper look at the work that really drives performance in elite sport.
Matt is the Head of Athletic Performance at Leicester Tigers, a former professional rugby player, and the founder of High Performance Puzzle. Having worked across both rugby union and rugby league, including Leicester Tigers and Catalan Dragons, Matt brings a rare combination of playing experience, coaching insight, leadership responsibility, and high-performance strategy.
In this episode, Richard and Matt explore the “invisible work” that sits behind successful performance environments. Not the gym programme. Not the GPS report. Not the testing data. But the conversations, decisions, relationships, standards, and judgement calls that determine whether the physical work actually lands.
They discuss why data needs context, how performance teams can align with coaches under pressure, what good decision-making looks like when information is incomplete, and why trust remains one of the most important currencies in elite sport.
For sports science, S&C, medical, coaching, and performance staff working in elite environments, this episode is a valuable reminder that high performance is not built by data alone. It is built through people, relationships, standards, and the ability to make good decisions when the pressure is on.
In this episode you will learn
Why the work that drives performance often sits outside the formal programme, session plan, or data report
How conversations between coaches, medical staff, S&C, sports science, and players provide vital context
What good alignment looks like in a high-performance environment
How to manage differing opinions between technical and performance departments
Why frameworks are essential when emotions and pressure start to influence decision-making
How to make better decisions when you do not have the complete picture
Why trust between the head coach, medical team, and performance staff is critical
How to use data without becoming over-reliant on it
Why standards often slip in small ways before they show up in performance outcomes
How relationships can make or break the effectiveness of even the best performance systems
Why gut feel still matters, provided it is shaped by experience and reflection
How elite practitioners can reflect more effectively on their own decisions and behaviours
Why discipline is a habit, not just a personal trait
What Matt has learned from working across rugby union and rugby league
Why the best players want honest feedback when standards start to slip
About Matt Parr
Matt Parr is Head of Athletic Performance at Leicester Tigers and founder of High Performance Puzzle.
Before moving into strength and conditioning, Matt spent around 14 to 15 years as a professional rugby player, representing clubs including Sale Sharks, Saracens, London Irish, and Leicester Tigers. His transition into performance coaching began at Leicester Tigers, where he initially combined a player-coach role with S&C responsibilities before moving fully into the performance department.
Matt has since built extensive experience across both rugby union and rugby league. After progressing through the performance setup at Leicester Tigers, he joined Catalan Dragons as Head of Performance, before returning to Leicester as Head of Athletic Performance.
Alongside his role in professional rugby, Matt has launched High Performance Puzzle, a consultancy focused on high-performance strategy, systems, leadership, and integration.
