330: Frontal Plane Fundamentals with Dr Matthew Ibrahim

Science for Sport — Mon, 27 Jul 2026 06:00:00 +0100

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.

329: The Five Qualities of Speed Development

Science for Sport — Mon, 20 Jul 2026 06:00:00 +0100

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. 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.

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.
