In this episode of VALDCAST, our host Ryan sits down with biomechanist and Griffith University researcher, Tyler Collings, to break down one of the most common and most misunderstood topics in sports technology: validity and reliability.

Tyler explains what these terms actually mean in practice, why they’re often confused and how human variability, testing protocols and “gold standards” influence the data practitioners rely on every day. The conversation unpacks common misconceptions in validation research, how to interpret reliability and validity papers and what practitioners should really be looking for when assessing performance and rehab technology.

They also dive into Tyler’s work validating field-based tools like force plates and strength testing devices, the importance of transparency in research and how laboratory findings translate into real-world performance and rehab settings.
