In this episode of the AFL Hub Performance Podcast, host Jack McLean interviews Alec, Head of Sports Science for the Adelaide Crows. The discussion dives deep into Tracking Athlete Performance Insights, with Alec sharing career tips for new biomechanists and exposing the hidden pitfalls of simplifying athlete data. Whether you’re working with elite teams or starting out, you’ll gain a fresh perspective on Tracking Athlete Performance Insights, learning why planning your next move is critical, how to democratize data without dumbing it down, and what tech tools are truly non-negotiable in a high-performance setting.
We also explore innovative tools like SpeedSig and how IMU-based stride analysis can uncover what traditional metrics miss. Whether you’re just starting out or looking to future-proof your high-performance program, this episode delivers insight straight from the field.
Tracking Athlete Performance Insights
Starting Smart: The Power of Preparation
Before launching into a new sports science or performance role, it’s critical to ensure all expectations are confirmed in writing. Alec Buttfield, a leading sports scientist, emphasized that while verbal support may seem promising, only written agreements provide clarity and security. Furthermore, he advises preparing for your next move before the current project ends. Transitioning smoothly requires foresight and a proactive mindset.
Core Metrics in Sports Science
Buttfield highlights the importance of key GPS metrics such as total time, total distance, high-speed running, and sprint distance. These figures are not just numbers—they are closely tied to both performance and injury prevention. Consequently, tracking them consistently allows coaches and athletes to make more informed decisions and improve game-day readiness.
Embracing Data Complexity
New sports scientists often oversimplify data. However, Buttfield stresses that the complexity of human performance must be respected. Reducing metrics too far may eliminate valuable nuances. Instead, building tools that capture the full training cycle—not just isolated snapshots—ensures a more holistic view of performance and athlete development.
SpeedSig: A Game-Changer
One standout tool mentioned is SpeedSig, which uses inertial measurement units (IMUs) to track running mechanics such as stride characteristics, ground contact time, and braking forces. Placed on the lower back, these sensors offer deeper insights into both movement efficiency and potential injury risk, especially during high-intensity efforts.
