Drake Berberet: Force Plates for Performance

Drake Berberet: Force Plates for Performance

August 15, 2022

On this episode we are joined by Drake Berberet. Drake is the Director of Sports Science at Hawkin Dynamics, a company that specializes in force plate technology. Drake also has experience as a strength coach in the collegiate and private sector that he uses to better understand what is tested with force plates.

Drake breaks down for us one of the most popular force plate tests, the countermovement jump and discusses its application to both the performance side of sports and return to play. We dive into the metrics that force plates measure and how to determine what an efficient jump looks like. We also discusses other topics such as injury mitigation, impulse, and go into specific examples of how patterns on force plates relate to athletic performance.
