336: How the NFL’s Best Practitioners Use Performance Data

Science for Sport — Mon, 07 Sep 2026 06:00:00 +0100

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

335: The Three Outcomes That Define High Performance

Science for Sport — Mon, 31 Aug 2026 06:00:00 +0100

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

334: How Elite Athletes Respond Under Pressure

Science for Sport — Mon, 24 Aug 2026 06:00:00 +0100

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

328: Blood Flow Restriction at the World Cup

Science for Sport — Mon, 13 Jul 2026 06:00:00 +0100

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

320: The Challenges of Modern Collegiate Sport

Science for Sport — Mon, 18 May 2026 06:00:00 +0100

This week on the Science for Sport Podcast, Richard Graves is joined by Heather Farmer, Assistant Athletics Director, Sports Science at the University of Nevada, Las Vegas.

Heather has been part of the UNLV athletics staff since 2016, first joining as Assistant Director of Strength and Conditioning before moving into sport science and later being promoted to Assistant Athletics Director for Sports Science in 2024.

In this episode, Heather shares how UNLV has built a sport science model from the ground up, why data should inform rather than dictate decisions, and how practitioners can create real buy-in across coaches, athletes, strength and conditioning, sports medicine, nutrition and psychology.

The conversation explores the realities of working in collegiate sport, from the impact of the transfer portal to the challenge of supporting athletes when timeframes are shorter and rosters are constantly changing. Heather also discusses the importance of female athlete data, the risks of over-relying on wearable technology, and why return-to-play decisions must go beyond timelines and basic fitness markers.

Throughout the episode, Heather brings the conversation back to one core principle: sport science is still about people. Data matters, technology matters, and AI may help practitioners work more efficiently, but the human side of performance remains central to everything.

In this episode you will learn

How Heather transitioned from collegiate soccer player to strength and conditioning coach, and then into sport science
Why UNLV built its sport science model around being “human first”
How to use data as an input rather than treating it as the final answer
Why coach buy-in is easier when practitioners build trust and show value over time
The challenges of applying male-dominated performance data to female athletes
How the transfer portal has changed long-term athlete development in collegiate sport
Why wearable technology can support performance but also create “analysis paralysis”
How UNLV approaches return to play using performance outputs, not just timelines
Why AI can support information gathering and efficiency, but cannot replace human judgement
The importance of speaking the language of other disciplines in a high-performance team

About Heather Farmer
Heather Farmer is the Assistant Athletics Director, Sports Science at UNLV. She has been with UNLV since 2016, initially working in strength and conditioning before moving into sport science leadership. Her work focuses on integrating data-informed approaches across the high-performance team while keeping the individual athlete at the centre of the process.

314: Player Load, Practice Periodisation, and the Art of Keeping It Simple with Jackson Polk

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

Richard Graves is joined by Jackson Polk, Director of Sports Science at the University of Southern California (USC), for a conversation that covers the full spectrum of what it actually means to do this job well, from wrangling a thousand Catapult metrics down to the handful that matter, to the perhaps surprising conclusion that conversation might be your most powerful tool.
Jackson's path into sports science isn't the conventional one. He started as a student videographer with Oklahoma football, found himself drawn to the patterns hiding in data, and taught himself enough statistics and analytics to make coaches stop and listen. That curiosity eventually took him from Norman, Oklahoma, to Los Angeles, where he's spent the past four years building USC football's sports science programme from the ground up.
What makes this episode stand out is Jackson's willingness to be honest about uncertainty, about AI, about his own mistakes, and about the limits of any single metric or method. He's equally at home referencing Principal Component Analysis and the TV show Veep, and that breadth of thinking is what makes him worth listening to. Whether you work in elite sport, study sports science, or just want to understand what goes into keeping a college football roster performing at its best, there's plenty here to take away.

In This Episode You Will Learn

Why reducing Catapult's thousand-plus metrics down to a focused few, Player Load, sprint volume, and repeat sprint exposures, actually produces better decisions than trying to monitor everything
How Jackson uses principal component analysis to build confidence in the data he's presenting to coaches and athletes
The "iceberg" model of athlete monitoring: what data can tell you, and what only a direct conversation will uncover
Why practice periodisation and load management have been one of USC's biggest organisational wins, and how PlayerLoad underpins that planning
How force plates (via VALD/ForceDecks) and velocity-based training tools like Perch complement GPS data to reveal readiness on any given day
The case for teaching college athletes sound recovery habits early, so they're not spending their rookie contracts figuring out what works
How Jackson thinks about AI in sports science: where it's useful, where to be cautious, and why it's only as good as the data it's trained on
Why communication, not technology, is the cornerstone of an effective sports science operation, and how to make data digestible for coaches under pressure
The value of building a culture where experimentation and failure are treated as learning, not liability
Lessons from Thinking in Bets by Annie Duke on separating process from outcome, applied directly to sports science decision-making

About Jackson Polk
Jackson Polk is the Director of Sports Science for USC Trojans football, a role he was elevated to in 2024 after serving as Assistant Director from 2022–23. He joined the USC support staff in March 2022, bringing with him an unconventional background that blends mathematics, data science, and a deep passion for American football.
His journey began at the University of Oklahoma, where he spent four seasons as a student videographer before becoming a volunteer performance analyst. While at OU, he co-founded the Oklahoma Sports and Data Analytics Club, which went on to win the Pro Football Focus Analytics Blitz contest. He completed his bachelor's degree in mathematics at Oklahoma in 2021 and subsequently pursued a master's in data science and analytics.
At USC, Jackson has been responsible for building the football programme's sports science infrastructure, integrating GPS monitoring, force plate testing, and load management into daily practice planning. He holds an MBA alongside his analytical credentials, and his work sits at the intersection of data science and high-performance sport.
