In this episode, Coach Ryan Patrick sits down with Dr. Sam Liu, biomechanist, researcher, and movement specialist with the Miami Marlins organization, to break down the true physics behind jumping, dunking, and speed.

They dive into what most coaches misunderstand about impulse, force, and timing — and how understanding the mechanical objective of movement changes everything. From countermovement jumps to approach takeoffs, Sam translates complex biomechanics into simple, actionable concepts every coach and athlete can apply.

If you’ve ever looked at a force plate trace or a highlight dunk and wondered what’s really happening there, this episode is for you.

Key Takeaways

✅ What great jumpers do with force

✅ Mechanical objectives simplify coaching by focusing on outcomes, not aesthetics.

✅ The biggest limiter to jump height 

✅ Force plates are tools → interpretation > data.

✅ The principles that make a better jumper also make a better pitcher or sprinter.
