But the real story goes beyond the helmets. How does a thin proprietary film inside each helmet capture and translate impact data? What insights can coaches extract from nearly a million recorded impacts across 13,000 secondary school athletes? And most intriguingly - could this massive data collection effort fundamentally change how we approach technique development and injury prevention in contact sports?

Join us as we dissect the technology with Riddell's Brian Kopp and explore the programme's implementation with the Broncos Foundation's Allie Engelken. We'll examine:
The science behind impact sensing technology
How real-time analytics are revolutionising coaching methodology
The potential implications for evidence-based practice in youth sports
Whether you're a sports scientist, strength coach, or performance specialist, this episode offers unprecedented insights into the future of data-driven player development.
This isn't just about American football - it's about understanding how technology can bridge the gap between elite and grassroots sports science.
