Rotational Power Testing, Eccentric Velocity, and Swing Performance | Ben Shear, Between 2 Sprints

Ben Shear has been using the 1080 Quantum for over 10 years, and the framework he's built around it is one of the more original applications in the space

His core idea: the Quantum functions as a rotary force plate. By orienting the athlete at specific angles relative to the cable, he can profile the eccentric, isometric, and concentric phases of a rotational movement the same way a force plate profiles a jump, and use the shape of that curve to direct training

The conversation covers how that testing protocol was developed, what it reveals about an athlete's rotary profile, and how Ben uses ground reaction force data from 3D golf force plates alongside the Quantum to connect movement capacity to loading strategy. The result is a system that can identify whether an athlete needs eccentric braking, rate of force development, or isometric stability in the transverse plane, and then prescribe accordingly

Topics covered:

-Why eccentric velocity matters more than eccentric load for injury prevention

-Using the Quantum as a rotary force plate: setup, orientation, and what the force curve reveals

-Counter-movement versus concentric-only rotation as a diagnostic tool

-Resistors and releasers: how Ben classifies athletes by their elasticity profile

-Connecting 3D ground reaction force data to cable orientation and loading strategy

-How horizontal, rotary, and vertical force production each map to a different training setup on the Quantum

-Using the Quantum as a report card: retesting to confirm whether the quality you trained actually changed

Ben's approach requires actually thinking about what the machine is measuring and why the setup matters. For coaches working in golf, baseball, tennis, or any rotary sport, this is a useful framework for getting more out of the data you already have
